Do childhood experiences influence associations between posttraumatic stress disorder symptoms and positive autobiographical memories among military veteran students? An exploratory study

ABSTRACT Background Evidence links posttraumatic stress disorder (PTSD) symptoms and features of positive autobiographical memories (accessibility, vividness, coherence, sharing, emotional intensity, distancing). There is a knowledge gap on how adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) may influence these relationships. Objectives The current study explored whether the number ACEs or BCEs moderated associations between PTSD symptom severity and features of positive autobiographical memories. Design and Methods The sample included 124 student military veterans who had experienced a trauma (M age = 33.90; 77.4% male; 75.0% White). Results Path analyses showed more PTSD symptom severity was significantly associated with less positive autobiographical memory vividness (β = −0.26, p = .019, R2 = 0.06). Further, the number of ACEs moderated the relationship between PTSD symptom severity and positive autobiographical memory accessibility (β = −0.25, p = .023, R2 = 0.10) and vividness (β = −0.20, p = .024, R2 = 0.10). Among individuals with more ACEs (1 SD above the mean) compared to those with fewer ACEs (1 SD below the mean), less accessibility and vividness of positive autobiographical memories was associated with greater PTSD symptom severity. The number of BCEs was not a significant moderator. Conclusions Positive memory-based interventions may be particularly useful to address PTSD symptoms among military veterans with a history of childhood adversity.

Impact of air pollution and climate change on mental health outcomes: an umbrella review of global evidence.

The impact of air pollution and climate change on mental health has recently raised strong concerns. However, a comprehensive overview analyzing the existing evidence while addressing relevant biases is lacking. This umbrella review systematically searched the PubMed/Medline, Scopus and PsycINFO databases (up to June 26, 2023) for any systematic review with meta-analysis investigating the association of air pollution or climate change with mental health outcomes. We used the R metaumbrella package to calculate and stratify the credibility of the evidence according to criteria (i.e., convincing, highly suggestive, suggestive, or weak) that address several biases, complemented by sensitivity analyses. We included 32 systematic reviews with meta-analysis that examined 284 individual studies and 237 associations of exposures to air pollution or climate change hazards and mental health outcomes. Most associations (n=195, 82.3%) involved air pollution, while the rest (n=42, 17.7%) regarded climate change hazards (mostly focusing on temperature: n=35, 14.8%). Mental health outcomes in most associations (n=185, 78.1%) involved mental disorders, followed by suicidal behavior (n=29, 12.4%), access to mental health care services (n=9, 3.7%), mental disorders-related symptomatology (n=8, 3.3%), and multiple categories together (n=6, 2.5%). Twelve associations (5.0%) achieved convincing (class I) or highly suggestive (class II) evidence. Regarding exposures to air pollution, there was convincing (class I) evidence for the association between long-term exposure to solvents and a higher incidence of dementia or cognitive impairment (odds ratio, OR=1.139), and highly suggestive (class II) evidence for the association between long-term exposure to some pollutants and higher risk for cognitive disorders (higher incidence of dementia with high vs. low levels of carbon monoxide, CO: OR=1.587; higher incidence of vascular dementia per 1 μg/m3 increase of nitrogen oxides, NOx: hazard ratio, HR=1.004). There was also highly suggestive (class II) evidence for the association between exposure to airborne particulate matter with diameter ≤10μm (PM10) during the second trimester of pregnancy and the incidence of post-partum depression (OR=1.023 per 1 μg/m3 increase); and for the association between short-term exposure to sulfur dioxide (SO2) and schizophrenia relapse (risk ratio, RR=1.005 and 1.004 per 1 μg/m3 increase, respectively 5 and 7 days after exposure). Regarding climate change hazards, there was highly suggestive (class II) evidence for the association between short-term exposure to increased temperature and suicide- or mental disorders-related mortality (RR=1.024), suicidal behavior (RR=1.012), and hospital access (i.e., hospitalization or emergency department visits) due to suicidal behavior or mental disorders (RR=1.011) or mental disorders only (RR=1.009) (RR values per 1°C increase). There was also highly suggestive (class II) evidence for the association between short-term exposure to increased apparent temperature (i.e., the temperature equivalent perceived by humans) and suicidal behavior (RR=1.01 per 1°C increase). Finally, there was highly suggestive (class II) evidence for the association between the temporal proximity of cyclone exposure and severity of symptoms of post-traumatic stress disorder (r=0.275). Although most of the above associations were small in magnitude, they extend to the entire world population, and are therefore likely to have a substantial impact. This umbrella review classifies and quantifies for the first time the global negative impacts that air pollution and climate change can exert on mental health, identifying evidence-based targets that can inform future research and population health actions.

High Prevalence of Psychological Comorbidities and Functional Neurological Symptoms in Women With Urinary Retention.

Chronic idiopathic urinary retention (CIUR) in young women is poorly understood and a probable etiology is established only in around 40%, most commonly a primary disorder of external urethral sphincter relaxation, sometimes referred to as Fowler's syndrome. A high prevalence of psychological and functional comorbidities is reported, however these have been poorly characterized. Women consecutively referred for the assessment and management of CIUR were evaluated cross-sectionally for 13 psychological/behavioral domains using a structured clinical interview: depression, anxiety, post-traumatic stress disorder (PTSD), other psychiatric history, functional neurological disorder, other functional syndromes, childhood and adult trauma, personality disorder, and self-harm (ever/current). A total of 91 women (mean age [SD]: 34 [11] years) were evaluated. Women with Fowler's syndrome (n = 69) were younger (mean age [SD]: 32 [9] vs 40 [13] years) than women without Fowler's syndrome and reported shorter mean duration of urinary symptoms (mean [SD]: 5 [6] vs 10 [9]). A high prevalence of psychiatric and psychological comorbidities was reported (97%) including current depression (77%), current anxiety (78%), and PTSD (32%). A high prevalence of functional neurological disorder (56%) and other functional symptoms (65%) was also reported. Self-harm was reported in (14%) and personality disorder in 16%. Childhood trauma was reported in 35% of women. Young women with CIUR report a high burden of psychiatric disorders, affective symptoms, trauma, PTSD, self-harm, and functional neurological disorder, particularly in those with Fowler's syndrome. These factors can undermine the engagement with health care professionals and affect management and should therefore be addressed during the urological assessment.

'Autism is the Arena and OCD is the Lion': Autistic adults' experiences of co-occurring obsessive-compulsive disorder and repetitive restricted behaviours and interests.

Repetitive behaviours and interests are a hallmark feature of autism. It is very common for autistic people to experience mental health difficulties, such as obsessive-compulsive disorder. Previous research has investigated similarities and differences between obsessive-compulsive disorder symptoms and repetitive behaviours in autism through questionnaires and observation studies. This is the first study to interview autistic adults about their personal experiences of differentiating between obsessive-compulsive disorder symptoms and repetitive behaviours related to autism. We interviewed 15 autistic adults who experience obsessive-compulsive disorder symptoms. We recorded these interviews and carefully analysed these to find themes. We found some differences between repetitive behaviours and obsessive-compulsive disorder. Participants said repetitive behaviours are part of who they are and what they want to be doing, whereas obsessive-compulsive disorder symptoms conflicted with how they view themselves. Obsessive-compulsive disorder was said to cause negative emotions, while participants said they experience lots of different emotions when doing repetitive behaviours. A similarity participants reported was trying to stop themselves from doing obsessive-compulsive disorder symptoms and repetitive behaviours that other people can see. There was also overlap between obsessive-compulsive disorder and repetitive behaviours. Participants talked about experiences when obsessive-compulsive disorder would take over routines and make them feel more intense and negative. Also, participants' special interests were sometimes connected to the obsessions they experienced. We conclude that clinicians can use these findings to support conversations with autistic clients in differentiating between repetitive behaviours and obsessive-compulsive disorder symptoms. We also think that further research investigating how obsessive-compulsive disorder symptoms might be hidden by autistic and typically developing people is needed.

The effect of social anxiety on threat acquisition and extinction: a systematic review and meta-analysis.

Although exposure-based therapy has been found to be effective at alleviating symptoms of social anxiety disorder, it often does not lead to full remission, and relapse after treatment is common. Exposure therapy is based on theoretical principles of extinction of conditioned fear responses. However, there are inconsistencies in findings across experiments that have investigated the effect of social anxiety on threat conditioning and extinction processes. This systematic review and meta-analysis aimed to examine whether elevated levels of social anxiety are associated with abnormalities in threat conditioning and extinction processes. A second aim was to examine the sensitivity of various study designs and characteristics to detect social anxiety-related differences in threat conditioning and extinction. A systematic search was conducted, which identified twenty-three experiments for inclusion in the review. The findings did not demonstrate compelling evidence that high levels of social anxiety are associated with atypical threat conditioning or extinction. Further, when systematically examining the data, there was no convincing support that the use of a particular psychophysiological measure, subjective rating, or experimental parameter yields more consistent associations between social anxiety and conditioning processes during threat acquisition or extinction. Meta-analyses demonstrated that during threat extinction, the use of anxiety ratings as a dependent variable, socially relevant unconditioned stimuli, and a higher reinforcement schedule produced more detectable effects of social anxiety on compromised extinction processes compared to any other dependent variable (subjective or physiological) or experimental parameter. Overall, the results of this study suggest that social anxiety is not reliably related to deficits in conditioning and extinction processes in the context of laboratory-based Pavlovian conditioning paradigms.

Alcohol milestones and internalizing, externalizing, and executive function: longitudinal and polygenic score associations.

Although the link between alcohol involvement and behavioral phenotypes (e.g. impulsivity, negative affect, executive function [EF]) is well-established, the directionality of these associations, specificity to stages of alcohol involvement, and extent of shared genetic liability remain unclear. We estimate longitudinal associations between transitions among alcohol milestones, behavioral phenotypes, and indices of genetic risk. Data came from the Collaborative Study on the Genetics of Alcoholism (n = 3681; ages 11-36). Alcohol transitions (first: drink, intoxication, alcohol use disorder [AUD] symptom, AUD diagnosis), internalizing, and externalizing phenotypes came from the Semi-Structured Assessment for the Genetics of Alcoholism. EF was measured with the Tower of London and Visual Span Tasks. Polygenic scores (PGS) were computed for alcohol-related and behavioral phenotypes. Cox models estimated associations among PGS, behavior, and alcohol milestones. Externalizing phenotypes (e.g. conduct disorder symptoms) were associated with future initiation and drinking problems (hazard ratio (HR)⩾1.16). Internalizing (e.g. social anxiety) was associated with hazards for progression from first drink to severe AUD (HR⩾1.55). Initiation and AUD were associated with increased hazards for later depressive symptoms and suicidal ideation (HR⩾1.38), and initiation was associated with increased hazards for future conduct symptoms (HR = 1.60). EF was not associated with alcohol transitions. Drinks per week PGS was linked with increased hazards for alcohol transitions (HR⩾1.06). Problematic alcohol use PGS increased hazards for suicidal ideation (HR = 1.20). Behavioral markers of addiction vulnerability precede and follow alcohol transitions, highlighting dynamic, bidirectional relationships between behavior and emerging addiction.

Impact of Orthodontic-Surgical Treatments on the Signs and Symptoms of Temporomandibular Disorders: A Systematic Review.

Some patients exhibit temporomandibular joint or muscular disorders of the masticatory system before, during, or after orthognathic surgery (OS). These are collectively referred to as temporomandibular disorders (TMDs). This systematic literature review aimed to determine the relationship between orthodontic-surgical treatment and TMDs. An electronic search of the PubMed database, supplemented by a manual search, was performed; the search included any studies published between 2021 (date of the last search in a systematic review of the literature on the subject) and June 2023 that evaluate the prevalence of TMDs during orthodontic-surgical treatment. The diagnosis of TMDs had to be established using the diagnostic algorithm "diagnostic criteria for temporomandibular disorders (DC/TMDs)", and the diagnosis of disc displacement had to be confirmed using magnetic resonance imaging (MRI). The data were extracted and statistically analyzed. Of the 100 results, seven eligible articles were included, representing a total of 529 cases undergoing orthodontic-surgical treatment. A reduction in joint noises (64.8%), arthralgia (57 to 77%), and myalgia (73 to 100%) was found after orthodontic-surgical treatment despite the fact that a minority of patients exhibited these signs and symptoms even though they were asymptomatic before treatment. The effects of OS on disc position were objectively unpredictable. After surgery, the presence of headaches decreased without significance and the risk of their occurrence was very low (1%). The studies converged toward a reduction in the amplitudes of mouth opening and lateral/protrusion movements. Finally, after the treatment, mandibular function was improved. Under the conditions of this study, OS seems to have a positive impact on the signs and symptoms of TMDs; however, it is not possible to predict the consequential effects on the position of the TMJ disc, whether it is initially in a normal position or displaced.

A Network Analysis of Symptoms of Post-Traumatic Stress Disorder and Facets of Mindfulness

Post-traumatic Stress Disorder (PTSD) is a mental health concern impacting a large proportion of the population. There is a growing interest in mindfulness-based treatments for PTSD. However, some individuals with PTSD do not respond to treatment. Identifying factors that may provide a more precise treatment approach has the potential to enhance response. Network analysis is a data-driven methodology that has been used to suggest specific targets for treatment. To date, there has not been a network analysis examining the interrelation between PTSD symptoms and trait mindfulness. The current study is an exploratory analysis of N = 214 adults from a non-clinical sample who endorsed a Criterion A traumatic event and completed the PTSD Checklist for DSM-5 and the Five Facet Mindfulness Questionnaire. Both undirected and directed networks were generated to identify links between PTSD symptom clusters and the facets of mindfulness. Both networks highlighted the connection between the PTSD symptom cluster Alterations in Arousal and Reactivity and the Awareness facet of mindfulness; and the PTSD symptom cluster Negative Alterations in Cognitions and Mood with the Non-judging facet of mindfulness. Taken together, these findings provide further evidence that greater mindfulness is generally associated with lower PTSD symptoms. Importantly, the findings highlight Non-judgement and Awareness as facets that might warrant further investigation in the context of mindfulness-based treatment efforts for PTSD.

Construct and Criterion Validation of Social Phobia Inventory Indonesian Version

Social anxiety disorder or SAD is a condition of abnormal anxiety experienced by individuals when they are facing a social situation. People with SAD usually tend to avoid social situations because they are afraid or anxious of getting a negative evaluation from other people. The negative impact for people with SAD is important for the need for measuring instruments that can detect the symptoms. The lack of SAD measurement tools in Indonesia is the reason why this validation study (SPIN) is important. The Social Phobia Inventory or SPIN is a self-report measurement tool for SAD symptoms and has good both in reliability and validity in several countries. This study aims to prove the validity and reliability of SPIN in Indonesia with 118 participants. The participants include people with SAD and healthy people. The result of this study that they are a convergent validity between SPIN and Social Cognition Questionnaire (SCQ), discriminant validity between SPIN and Patient Health Questionnaire (PHQ) that evaluate eating disorder and alcohol abuse symptoms, and also SPIN have 66% of sensitivity and 100% of specificity using Liebowitz Social Anxiety Scale (LSAS). This study can be used by professionals to assist in determining an objective diagnosis in individuals with symptoms of SAD using SPIN since SPIN is one of the gold standard to measure social anxiety symptoms.

Eating Disorder Treatment Access in the United States: Perceived Inequities Among Treatment Seekers.

Although eating disorders are associated with high rates of psychological and physical impairments and mortality, only about 20% of individuals with eating disorders receive treatment. No study has comprehensively assessed treatment access for those with these disorders in the United States. The authors examined access to eating disorder treatments and how it might vary among some populations. Seekers of treatment for eating disorders (N=1,995) completed an online assessment of clinical demographic and anthropometric characteristics, barriers to eating disorder treatment access, and eating disorder symptomatology. Analyses were conducted to identify treatment access barriers, compare barriers to treatment access across demographic groups, and investigate relationships between barriers to treatment access and eating disorder symptoms. Financial barriers (e.g., lack of insurance coverage) were the most frequently reported barrier to treatment access. Participants with historically underrepresented identities and with a diagnosis of other specified feeding or eating disorder (OSFED) reported more barriers related to financial challenges, geographic location, eating disorder identification, sociocultural factors, and treatment quality compared with those with historically represented identities (e.g., White and cisgender persons). Higher frequencies of reported barriers to treatment access were associated with more severe eating disorder symptoms and poorer illness trajectories. Financial barriers were the most significant impediment to accessing treatment among individuals seeking eating disorder treatment. Barriers to treatment access disproportionally affected underrepresented groups and those with an OSFED diagnosis.

Brain, behavior, cognition, and physical health in first-onset adolescent anorexia nervosa: The BRAVE Study design and cohort profile

Background Anorexia nervosa is a severe psychiatric disorder with a heterogeneous course with one of the highest rates of morbidity and mortality of all psychiatric disorders. Little is known about factors that predict both course and treatment outcomes of this disorder. The BRAVE Study is a longitudinal first-onset anorexia nervosa cohort study focusing on four topics of interest in girls only: (1) behavior, (2) neurobiology, (3) cognitive functions, and (4) physical health. Objective The goal of this paper is to introduce the BRAVE Study. The primary aim of the BRAVE Study is to identify predictors of treatment response in a large sample of 12-to-22-year-old females with first-onset typical or atypical anorexia nervosa. The second aim is to longitudinally investigate the association between clinically significant changes in eating disorder symptoms with the underlying behavioral, neurobiological, cognitive and physical health changes. The results of this study will allow us to develop more precise treatment strategies in order to provide more optimal treatment. Methods and analysis The BRAVE Study implements a longitudinal case-control design. Study recruitment was designed within a collaborative network of 16 Dutch mental health organizations, each with expertise in the diagnosis and treatment of patients with anorexia nervosa. After obtaining informed consent, assessments were performed at baseline and one-year follow-up. Patients with anorexia nervosa received treatment as usual. The primary outcome measures at one year are restoration of weight and a reduction of eating disorder symptomatology. Predictive measures include neurobiological, cognitive, behavioral and physical health measures. Sample description In the BRAVE Study 79 girls with anorexia nervosa and 75 typically developing girls were included between May 2017 and October 2021. This period of time partially overlapped with the COVID-19 pandemic. 72% of the girls with anorexia nervosa and 88% of the typically developing girls also completed measurements at follow-up. The mean time between data collections points was 13 months. The groups were comparable in education level of their mothers, neurodevelopmental disorders, and ethnical background. The girls with anorexia nervosa were slightly younger than the typically developing girls. Conclusion The BRAVE Study aligns with one of the most important study priorities in the field of anorexia nervosa by examining (i) predictors of treatment response and (ii) investigating how symptoms with eating disorder symptoms track with changes in neurobiological, cognitive, behavorial and physical health functioning. Moreover, the study is innovative by its longitunal case control design, relatively large study sample and broad selection of measures.

Panic Disorder Versus Thyroid Medication Overuse: A Case Report

Introduction: Panic disorder is defined as the occurrence of spontaneous panic attacks that are not triggered by any specific stimulus. The symptoms of panic disorder include panic episodes that occur frequently and unexpectedly, as well as anxiety about the possibility of experiencing further panic attacks, the repercussions of panic attacks, or a change in behavior as a result of panic attacks. This study presented the diagnosis and treatment of panic disorder comorbid with thyroid medication overuse. Case presentation: A 36-year-old female patient presented to the emergency room with a primary concern and symptoms consistent with panic disorder, including experiencing a sense of losing control or impending death, chest pain, difficulty breathing, rapid heartbeat, excessive perspiration, trembling, and dizziness. The patient experienced significant periods of anxiety between episodes, preoccupied with the anticipation of the next occurrence. Each episode had a duration of roughly 15 minutes. The patient refutes any history of alcohol or drug misuse, and her sole medical condition is hypothyroidism. Subsequently, we perform a comprehensive analysis of the thyroid profile and make a referral to an internal medicine specialist for collaborative treatment. We treated the patient with a combination of a selective serotonin reuptake inhibitor (SSRI) fluoxetine 20 mg/day and a course of cognitive-behavioral therapy. Conclusion: Repeated episodes of intense panic attacks, accompanied by feelings of anxiety and observable alterations in behavior, distinguish panic disorder as a medical illness. The treatment involves the use of selective serotonin reuptake inhibitors, antidepressants, and cognitive behavioral therapy.

International Trauma Questionnaire and Posttraumatic Cognitions Inventory-9: validity evidence and measurement invariance of their Brazilian versions

BackgroundThe International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.ObjectiveThis study examined the validity, reliability, and measurement invariance of the Brazilian versions of the ITQ and the PTCI-9 for trauma type, gender, race, age group, education level, and geographical region.MethodsA total of 2,111 people (67.74% women) participated in an online survey. The scale models were tested via confirmatory factor analyses and measurement invariance through multigroup analyses. Pearson’s correlation analyses were used to examine the relationships between PTSD, CPTSD, posttraumatic cognitions, and depressive symptoms.ResultsExcept for the affective dysregulation factor, the reliabilities of the ITQ and PTCI-9 dimensions were adequate. Models with six correlated dimensions for the ITQ and three correlated dimensions for the PTCI-9 showed adequate fit to the data. The ITQ and PTCI-9 exhibited scalar invariance for gender, race, age group, education level, and geographical region. The ITQ also demonstrated full invariance for trauma type. The factors of both instruments were related to each other and to depressive symptoms, with higher effect sizes for posttraumatic cognitions and complex posttraumatic stress disorder symptoms.ConclusionWe recommend using the Brazilian versions of the ITQ and PTCI-9, which are crucial tools for assessing and treating trauma-related disorders.

Efficacy of a transdiagnostic internet-based program for adolescents with emotional disorders: A randomized controlled trial

ObjectiveThe Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) is a well-established transdiagnostic cognitive-behavioral therapy (T-CBT) intervention. The aim of the present study was to examine the efficacy of the program Learn to Manage your Emotions [Aprende a Manejar tus Emociones] (AMtE), a self-applied transdiagnostic internet-delivered program based on the Spanish version of the UP-A. This is the first transdiagnostic internet-based program designed for the treatment of emotional disorders in adolescents. MethodA sample of Spanish adolescents with a primary diagnosis of an anxiety and/or depressive disorder (n = 58; age range = 12–18 years; 78.3% girls; 90% Caucasian) were randomly allocated to receive AMtE (n = 28) or the UP-A via videocall (n = 30). Pre-treatment, post-treatment and 3-month follow-up data were collected using self-reports and clinician-rated measures of anxiety, depression, positive and negative affect, anxiety sensitivity and emotional avoidance. ResultsBased on generalized estimating equations (GEE) models, both intervention programs were effective in significantly reducing self-reported anxiety and depressive disorder symptoms and clinician-rated severity of anxiety and depression, as well as self-reported transdiagnostic outcome variables. ConclusionsData provide empirical support for the efficacy of AMtE as a transdiagnostic online CBT treatment for anxiety and depressive disorders in adolescents. No marked nor consistent differences were observed between the UP-A and AMtE, highlighting the potential usefulness of the online self-administered AMtE program.

Social communication and restricted, repetitive behavior as assessed with a diagnostic tool for autism (ADOS-2) in women with anorexia nervosa.

In anorexia nervosa (AN), the traits of autism spectrum disorder (ASD) are associated with poor outcomes. However, the subtle nature of these characteristics remains poorly understood. We investigated the in-depth patterns of ASD traits using Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) in women with AN. Of 28 women with ICD-10 AN, 16 (age 19-30 years) participated in the ADOS-2, a video-recorded, semistructured diagnostic assessment for social communication and interaction and restricted, repetitive behaviors and interests related to ASD. None of the participants had previously been diagnosed with ASD. Other measurements included the Eating Disorder Examination Questionnaire and the Wechsler Abbreviated Scale of Intelligence-IV. Five individuals (18% of all, 31% of those assessed) scored above the cutoff for autism in ADOS-2. They had challenges in social communication and interaction, manifesting as sustained difficulties in social relationships and deficits in conversation skills. Few described being frequently misunderstood by others, including in the eating disorder treatment settings. Three individuals showed prominent restricted and repetitive behaviors such as ritual seeking, eating-related routines, sensory sensitivity related to food texture and selective eating, and intense interest in specific topics. The mean duration of AN in women above the cutoff was twice as long compared with those below (12.3 vs. 6.2 years). The ASD-related characteristics and behavior appear to contribute to the manifestation and duration of AN in a subgroup of women. Among these women, the traits of ASD appear to be mixed with eating disorder symptoms, which should be taken into account in the treatment.

Persistent increased severity of cannabis use disorder symptoms in adolescents compared to adults: a one-year longitudinal study.

Adolescence is a developmental period characterised by increased vulnerability to cannabis use disorder (CUD). However, previous investigations of this vulnerability have relied on cross-sectional comparisons and lack a detailed assessment of cannabis quantity, a potentially important confounding factor. Here, we aimed to investigate the one-year course of CUD in adolescents compared to adults who currently use cannabis, adjusting for a comprehensive measure of cannabis quantity. Data are from a one-year observational longitudinal study (CannTeen) of adolescents and adults who currently used cannabis regularly with five waves of assessment at 3-monthly intervals, based in London, UK. Participants were n = 70 adults (26-29, 45.7% female), who did not regularly use cannabis when they were under age 18, and n = 76 adolescents (16-17, 50.0% female). The exposure was adolescent (compared to adult) frequent cannabis use. The primary outcome was CUD symptoms measured using the cannabis use disorder identification test revised (CUDIT-R) at five time points. Models were adjusted for cannabis quantity using mean weekly standard THC units (one unit = 5mg THC). Other covariates included gender, and whether each session occurred before or during the COVID-19 pandemic. In models adjusted for pre-registered covariates, adolescents scored 3.7 points higher on the CUDIT-R compared to the adult group across the 5 assessment waves (3.66 95% CIs 1.99, 5.34). There was also evidence of a linear reduction in symptoms over time in both groups (-0.47, 95%CIs -0.67, -0.27). Adolescents had persistently increased CUD symptoms compared to adults across the 12-month period. This association was robust after adjusting for the quantity of cannabis consumed and other covariates.

Implementation of the Recovery Model and Its Outcomes in Patients with Severe Mental Disorder.

The recovery model assumes that the patient can experience personal growth even while maintaining symptoms of a mental disorder. In order to achieve this recovery, the practices of professionals must also change. However, in our setting, there are limited data on the implementation of practices based on the recovery model and their effect on personal recovery. To describe the association between professionals' practices and patients' personal recovery. An observational and cross-sectional study in which the Recovery Self-Assessment (RSA) was used to assess the degree of implementation of the different practices and the Recovery Assessment Scale (RAS) was used to assess the personal recovery of 307 patients with severe mental disorders. Patients attended by professionals who followed the recovery model obtained a greater personal recovery (p < 0.001, d = 1.10). The dimension associated with greater recovery was that of working toward life goals. The least implemented dimensions had to do with offering treatment options and patient participation in decision-making. This study was conducted in accordance with STROBE (STrengthening the Reporting of OBservational studies in Epidemiology). Although this is a cross-sectional study that does not allow us to establish causal relationships, it shows that the model with which mental health professionals work is associated with patients' chances of recovery. We therefore consider that it is important to foster the implementation of practices based on the recovery model within mental health care.

Attention-deficit/hyperactivity disorder: clinical phenotypes, polymorphism of life-course manifestations, and therapeutic strategies

Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral disorder that manifests in childhood and persists into adulthood. The prevalence of ADHD (USA/worldwide) in children and adolescents is 9.5/5.29 %, in adults — 4.4/2.5 %. The disorder has strong genetic correlations with numerous mental disorders and neurological diseases, in particular with post-traumatic stress disorder, addiction to cannabis, cocaine, recurrent and bipolar affective disorders, behavioral disorders, which is the biological basis of its clinical polymorbidity. Symptoms of ADHD overlap with other clinical manifestations of neurodevelopmental disorders (symptoms of autistic spectrum disorders, speech disorders, movement disorders, dyslexia, cognitive impairment), forming a polymorphic spectrum of pervasive developmental variants. Psychostimulants have been the standard of ADHD treatment for over 50 years. In 2002, atomoxetine became the first nonstimulant medication approved by the Food and Drug Administration for the treatment of ADHD, first in children and later in adult patients. Stimulant and nonstimulant medications have been shown to be effective in different phenotypes of ADHD (comorbidity with other mental and neurological disorders). In case of comorbidity of ADHD with anxiety, tics, atomoxetine has an advantage over stimulants and, together with alpha-2-adrenergic receptor agonists, can be recommended as the first drug. The presence of comorbid anxiety disorder or recurrent depression does not impact the efficacy and side effects of atomoxetine. Thus, atomoxetine is an effective drug and not only improves the symptoms of ADHD, but also plays a certain role in the treatment of patients with comorbid depression and anxiety.

Associations between trauma exposure and irritability within the family unit: a network approach.

Pediatric irritability is a pervasive psychiatric symptom, yet its etiology remains elusive. While trauma exposure may contribute to the development of irritability, empirical research is limited. This study examined the prevalence of irritability among trauma-exposed children, identified factors that differentiate trauma-exposed children with and without irritability, and employed a network analysis to uncover associations between irritability and trauma exposure in the family unit. Sample included 676 children (56.3% male, mean age = 9.67 ± 3.7 years) and their parents referred by the Connecticut Department of Children and Families to Fathers for Change - a psychotherapy intervention designed to reduce intimate partner violence (IPV) and child maltreatment. Child's trauma exposure, post-traumatic stress disorder (PTSD) symptoms, and irritability were assessed pre-intervention using self- and caregiver-report. Parents self-reported their childhood and adulthood trauma exposures, PTSD symptoms, irritability, psychopathology, and IPV. Across caregiver- and child-reports, 16%-17% of children exhibited irritability. Irritable children experienced greater trauma exposure, interpersonal violence, emotional abuse, and PTSD severity. They had caregivers, particularly mothers, with greater trauma histories, IPV, and psychopathology. Network analysis revealed 10 nodes directly correlated to child's irritability including child's PTSD severity, parental IPV (specifically psychological violence), and parental psychopathology. Results provide initial empirical evidence that pediatric irritability is linked to trauma exposure, suggesting trauma histories be considered in the diagnosis and treatment of irritability. Interventions addressing caregiver trauma, IPV, and psychopathology may ameliorate pediatric irritability. Future studies could benefit from adopting network approaches with longitudinal or time series data to elucidate causality and points of intervention.

Association between pathological narcissism and emotion regulation: The role of self-mentalizing?

Pathological narcissism (PN) is a common psychopathological issue leading to maladaptive strategies to cope with self-esteem threats, including self-enhancement and exploitation (grandiose strategies) or internalized shame, depression, and social withdrawal (vulnerable strategies). Mentalizing is a key process for regulating self and other representations and their associated emotions. Patients with PN further struggle with emotion dysregulation (ED), which during development is intertwined with the growing capacity to mentalize. We seek to contribute to emerging empirical data documenting the associations between PN and ED and between PN and mentalizing, and to provide information on the nature of their mutual relationships. In the present study, we assessed PN, ED, and three mentalizing dimensions (mentalizing self, other, and motivation to mentalize) in 183 patients consulting in our outpatient unit specialized in ED. We found that narcissistic vulnerability was negatively associated with self-mentalizing and positively associated with overall ED, both even after adjustment for borderline and attention deficit hyperactivity disorder (ADHD) symptoms. However, the association with ED was not maintained after further adjustment for self-mentalizing or overall-mentalizing, which suggests that mentalizing may play a mediating role in this relationship. On the other hand, narcissistic grandiosity was positively associated with other-mentalizing and ED and negatively associated with self-mentalizing in bivariate analyses, but these last two associations were not maintained after adjustment for comorbid borderline and/or ADHD symptomatology. This study provides new information on the link between PN and ED and on key mentalizing dimensions meaningfully relating to PN, notably through a potential role of self-mentalizing processes between PN and ED.
