Quality of life in pediatric patients with obsessive-compulsive disorder during and 3years after stepped-care treatment.

The present study aimed to investigate the long-term quality of life (QoL) in a large sample of pediatric obsessive-compulsive disorder (OCD) patients. The study included 220 pediatric OCD patients from the Nordic Long-term OCD Treatment Study (NordLOTS) who were evaluated at seven time points before, during, and after stepped-care treatment over a 3-year follow-up period. Data from three symptom severity trajectory classes formed the basis of the QoL evaluation: acute (n = 127, N = 147), slow (n = 46, N = 63), and limited responders (n = 47, N = 59). Patients' QoL was assessed using parent and child ratings of the revised Questionnaire for Measuring Health-related Quality of Life in Children and Adolescents (KINDL-R). QoL was analyzed by trajectory class using a random mixed effects model. The association between pre-treatment factors and long-term QoL was investigated across classes in a multivariate model. Three years after treatment, the acute responder class had reached QoL levels from a general population, whereas the limited responder class had not. The slow responder class reached norm levels for the child-rated QoL only. Higher levels of co-occurring externalizing symptoms before treatment were associated with lower parent-rated QoL during follow-up, while adolescence and higher levels of co-occurring internalizing symptoms were associated with lower child-rated QoL during follow-up. For some patients, residual OCD symptoms in the years after treatment, even at levels below assumed clinical significance, are associated with compromised QoL. Co-occurring symptoms could be part of the explanation. Assessing QoL after OCD treatment, beyond the clinician-rated symptom severity, could detect patients in need of further treatment and/or assessment.

Translating evidence-based psychological interventions for older adults with depression and anxiety into public and private mental health settings using a stepped care framework: Study protocol

BackgroundWith expected increases in the number of older adults worldwide, the delivery of stepped psychological care for depression and anxiety in older populations may improve both treatment and allocative efficiency for individual patients and the health system. DesignA multisite pragmatic randomised controlled trial evaluating the clinical and cost-effectiveness of a stepped care model of care for treating depression and anxiety among older adults compared to treatment as usual (TAU) will be conducted. Eligible participants (n = 666) with clinically interfering anxiety and/or depression symptoms will be recruited from and treated within six Australian mental health services. The intervention group will complete a low intensity cognitive behavioural therapy (CBT) program: Internet-delivered or using a work-at-home book with brief therapist calls (STEP 1). Following STEP 1 a higher intensity face-to-face CBT (STEP 2) will then be offered if needed. Intention-to-treat analyses will be used to examine changes in primary outcomes (e.g. clinician-rated symptom severity changes) and secondary outcomes (e.g. self-reported symptoms severity, health related quality of life and service utilisation costs). An economic evaluation will be conducted using a cost-utility analysis to derive the incremental cost-effectiveness ratio for the stepped care intervention. DiscussionThis study will demonstrate the relative clinical and economic benefits of stepped care model of psychological care for older adults experiencing anxiety and/or depression compared to TAU. The evaluation of the intervention within existing mental health services means that results will have significant implications for the translation of evidence-based interventions in older adult services across urban and rural settings.

Yale Global Tic Severity Scale (YGTSS): Psychometric Quality of the Gold Standard for Tic Assessment Based on the Large-Scale EMTICS Study.

The Yale Global Tic Severity Scale (YGTSS) is a clinician-rated instrument considered as the gold standard for assessing tics in patients with Tourette's Syndrome and other tic disorders. Previous psychometric investigations of the YGTSS exhibit different limitations such as small sample sizes and insufficient methods. To overcome these shortcomings, we used a subsample of the large-scale “European Multicentre Tics in Children Study” (EMTICS) including 706 children and adolescents with a chronic tic disorder and investigated convergent, discriminant and factorial validity, as well as internal consistency of the YGTSS. Our results confirm acceptable convergent and good to very good discriminant validity, respectively, indicated by a sufficiently high correlation of the YGTSS total tic score with the Clinical Global Impression Scale for tics (rs = 0.65) and only low to medium correlations with clinical severity ratings of attention deficit/hyperactivity symptoms (rs = 0.24), obsessive–compulsive symptoms (rs = 27) as well as internalizing symptoms (rs = 0.27). Internal consistency was found to be acceptable (Ω = 0.58 for YGTSS total tic score). A confirmatory factor analysis supports the concept of the two factors “motor tics” and “phonic tics,” but still demonstrated just a marginal model fit (root mean square error of approximation = 0.09 [0.08; 0.10], comparative fit index = 0.90, and Tucker Lewis index = 0.87). A subsequent analysis of local misspecifications revealed correlated measurement errors, suggesting opportunities for improvement regarding the item wording. In conclusion, our results indicate acceptable psychometric quality of the YGTSS. However, taking the wide use and importance of the YGTSS into account, our results suggest the need for further investigations and improvements of the YGTSS. In addition, our results show limitations of the global severity score as a sum score indicating that the separate use of the total tic score and the impairment rating is more beneficial.

A Two-to-Five Year Follow-Up of a Pediatric Acute-Onset Neuropsychiatric Syndrome Cohort

Little is known about the long-term prognosis of children with pediatric acute-onset neuropsychiatric syndrome (PANS). Out of the 46 eligible patients from the Karolinska PANS cohort, 34 consented to participate in a follow-up (median 3.3 years). Participants underwent a thorough clinical evaluation and were classified according to their clinical course. Resulting groups were compared on clinical characteristics and laboratory test results. We observed significant reductions in clinician-rated PANS symptom severity and improved general function. Two patients were classified as remitted, 20 as relapsing–remitting, and 12 as having a chronic-static/progressive course. The latter group had an earlier onset, greater impairment and received more pharmacological and psychological treatments. Although remission was rare, the majority of children with PANS were significantly improved over the follow-up period but a non-negligible minority of patients displayed a chronic-static/progressive course and required additional treatments. The proposed definitions of flare and clinical course may be useful in future clinical trials.

Homework Compliance and Quality in Cognitive Behavioral Therapies for Anxiety Disorders and Obsessive-Compulsive Disorder

Homework assignments are an integral part of cognitive behavioral therapy, providing patients with opportunities to practice skills between sessions. Generally, greater homework compliance is associated with better treatment outcomes. However, fewer studies have examined the effect of homework quality on treatment outcomes. This study examined homework compliance and quality as predictors of outcome and attrition across five CBT protocols. A sample of 179 individuals with principal diagnoses of generalized anxiety disorder, panic disorder, social anxiety disorder, or obsessive-compulsive disorder were randomized to receive a transdiagnostic CBT protocol (the Unified Protocol) or a single-diagnosis CBT protocol corresponding to their principal diagnosis. The Unified Protocol had a lower homework burden than the majority of the single-diagnosis protocols, which varied in degree of assigned homework. Despite this, there were no differences in average homework compliance or quality across principal diagnosis, treatment condition, or their interaction. Homework quality was significantly related to all symptom outcomes (self-reported and clinician-rated anxiety and depressive symptoms, clinician-rated clinical severity). Homework compliance was significantly related to clinician-rated anxiety symptom outcomes. Additionally, greater homework quality and compliance were both significantly associated with increased odds of completing treatment, suggesting homework variables can be useful and easily obtainable predictors of treatment retention.

Smartphone-Based Self-Reports of Depressive Symptoms Using the Remote Monitoring Application in Psychiatry (ReMAP): Interformat Validation Study.

BackgroundSmartphone-based symptom monitoring has gained increased attention in psychiatric research as a cost-efficient tool for prospective and ecologically valid assessments based on participants’ self-reports. However, a meaningful interpretation of smartphone-based assessments requires knowledge about their psychometric properties, especially their validity.ObjectiveThe goal of this study is to systematically investigate the validity of smartphone-administered assessments of self-reported affective symptoms using the Remote Monitoring Application in Psychiatry (ReMAP).MethodsThe ReMAP app was distributed to 173 adult participants of ongoing, longitudinal psychiatric phenotyping studies, including healthy control participants, as well as patients with affective disorders and anxiety disorders; the mean age of the sample was 30.14 years (SD 11.92). The Beck Depression Inventory (BDI) and single-item mood and sleep information were assessed via the ReMAP app and validated with non–smartphone-based BDI scores and clinician-rated depression severity using the Hamilton Depression Rating Scale (HDRS).ResultsWe found overall high comparability between smartphone-based and non–smartphone-based BDI scores (intraclass correlation coefficient=0.921; P<.001). Smartphone-based BDI scores further correlated with non–smartphone-based HDRS ratings of depression severity in a subsample (r=0.783; P<.001; n=51). Higher agreement between smartphone-based and non–smartphone-based assessments was found among affective disorder patients as compared to healthy controls and anxiety disorder patients. Highly comparable agreement between delivery formats was found across age and gender groups. Similarly, smartphone-based single-item self-ratings of mood correlated with BDI sum scores (r=–0.538; P<.001; n=168), while smartphone-based single-item sleep duration correlated with the sleep item of the BDI (r=–0.310; P<.001; n=166).ConclusionsThese findings demonstrate that smartphone-based monitoring of depressive symptoms via the ReMAP app provides valid assessments of depressive symptomatology and, therefore, represents a useful tool for prospective digital phenotyping in affective disorder patients in clinical and research applications.

Effect of Prolonged Exposure, intensified Prolonged Exposure and STAIR+Prolonged Exposure in patients with PTSD related to childhood abuse: a randomized controlled trial

ABSTRACT Background: It is unclear whether the evidence-based treatments for PTSD are as effective in patients with CA-PTSD. Objective: We aimed to investigate the effectiveness of three variants of prolonged exposure therapy. Method: We recruited adults with CA-PTSD. Participants were randomly assigned to Prolonged Exposure (PE; 16 sessions in 16 weeks), intensified Prolonged Exposure (iPE; 12 sessions in 4 weeks followed by 2 booster sessions) or a phase-based treatment, in which 8 sessions of PE were preceded by 8 sessions of Skills Training in Affective and Interpersonal Regulation (STAIR+PE; 16 sessions in 16 weeks). Assessments took place in week 0 (baseline), week 4, week 8, week 16 (post-treatment) and at a 6-and 12-month follow-up. The primary outcome was clinician-rated PTSD symptom severity. Results: We randomly assigned 149 patients to PE (48), iPE (51) or STAIR+PE (50). All treatments resulted in large improvements in clinician assessed and self-reported PTSD symptoms from baseline to 1-year follow-up (Cohen’s d > 1.6), with no significant differences among treatments. iPE led to faster initial symptom reduction than PE for self-report PTSD symptoms (t 135 = −2.85, p = .005, d = .49) but not clinician-assessed symptoms (t135 = −1.65, p = .10) and faster initial symptom reduction than STAIR+PE for self-reported (t 135 = −4.11, p < .001, d = .71) and clinician-assessed symptoms (t 135 = −2.77, p = .006, Cohen’s d = .48) STAIR+PE did not result in significantly more improvement from baseline to 1-year follow-up on the secondary outcome emotion regulation, interpersonal problems and self-esteem compared to PE and iPE. Dropout rates did not differ significantly between conditions. Conclusions: Variants of exposure therapy are tolerated well and lead to large improvements in patients with CA-PTSD. Intensifying treatment may lead to faster improvement but not to overall better outcomes.

Pre-Loss Group Therapy for Family Caregivers of Persons With Dementia: Translation Into Practice

We developed Pre-Loss Group Therapy (PLGT) for dementia caregivers at risk for Complicated Grief (CG). PLGT is a manualized ten-session multi-modal group therapy that includes elements of cognitive behavior therapy, motivational interviewing, exposure therapy, memory revisiting, meaning-making, and self-care. We implemented and evaluated three PLGT cohorts in three long-term care facilities with family caregivers at-risk for CG whose care recipient had a life expectancy of 6 months or less and resided in a long-term care facility (NT = 24). Evaluation of participant preparedness for the death of the persons with dementia (PWD), self-care and grief outcomes showed significant improvement across multiple domains between pre and post-group, notably a statistically significant decrease in grief as measured by the Inventory of Complicated Grief score from baseline (M = 25.67, SE=1.80) to post-group (M = 14.41, SE=1.65) t(21)= 6.280, p<0.001. Clinician-rated grief severity declined (N=22, β = –0.472, SE = 0.018, p < 0.001) per week and grief improvement increased (N=22, β = 0.259, SE = 0.023, p < 0.001) per week, as assessed on the Clinician Global Impressions Scale. We subsequently trained two LCSWs to conduct PLGT, and both clinical outcomes and treatment fidelity and skills measures achieved performance levels of master clinician-trainers. Family caregivers at risk for CG may benefit from group therapy targeting preparedness and pre-loss grief experience, as we provide with PLGT. Manualized PLGT is suitable for implementation by LCSWs in the settings of hospice and long-term care.

Effectiveness of a Guided Internet- and Mobile-Based Intervention for Patients with Chronic Back Pain and Depression (WARD-BP): A Multicenter, Pragmatic Randomized Controlled Trial

Introduction: There is neither strong evidence on effective treatments for patients with chronic back pain (CBP) and depressive disorder nor sufficiently available mental health care offers. Objective: The aim is to assess the effectiveness of internet- and mobile-based interventions (IMI) as a scalable approach for treating depression in a routine care setting. Methods: This is an observer-masked, multicenter, pragmatic randomized controlled trial with a randomization ratio of 1:1.Patients with CBP and diagnosed depressive disorder (mild to moderate severity) were recruited from 82 orthopedic rehabilitation clinics across Germany. The intervention group (IG) received a guided depression IMI tailored to CBP next to treatment-as-usual (TAU; including medication), while the control group (CG) received TAU. The primary outcome was observer-masked clinician-rated Hamilton depression severity (9-week follow-up). The secondary outcomes were: further depression outcomes, pain-related outcomes, health-related quality of life, and work capacity. Biostatistician blinded analyses using regression models were conducted by intention-to-treat and per protocol analysis. Results: Between October 2015 and July 2017, we randomly assigned 210 participants (IG, n = 105; CG, n = 105), mostly with only a mild pain intensity but substantial pain disability. No statistically significant difference in depression severity between IG and CG was observed at the 9-week follow-up (β = –0.19, 95% CI –0.43 to 0.05). Explorative secondary depression (4/9) and pain-related (4/6) outcomes were in part significant (p < 0.05). Health-related quality of life was significantly higher in the IG. No differences were found in work capacity. Conclusion: The results indicate that an IMI for patients with CBP and depression in a routine care setting has limited impact on depression. Benefits in pain and health-related outcomes suggest that an IMI might still be a useful measure to improve routine care.

Transdiagnostic Cognitive Behavioural Therapy for Individuals with Anxiety Disorders: An Open Trial

AbstractObjective:To evaluate the effect of a transdiagnostic cognitive behavioural therapy (tCBT) protocol in an individual delivery format, adapted from a protocol that has been extensively evaluated in a group delivery format.Method:tCBT was provided to a cohort (N = 18) of adults with a range of anxiety disorders (55.6% male; M age = 40.6, SD = 17.6), at a speciality anxiety disorder research clinic. A within-subjects repeated measures design was employed. Pre-to-post-treatment diagnostic assessments were analysed through repeated measures analysis of variance, and session-by-session self-reported measures of anxiety, depression, and quality of life were modelled through mixed-effect regression modelling (MRM) to maximise the sample of treatment initiators.Results:Significant and large reductions for clinician-rated primary diagnosis severity (Hedges g = 1.63), and overall clinical global impressions (g = 1.43) were observed, and self-reported anxiety and depression symptoms showed significant reductions over the course of treatment with medium-to-large effect sizes (g = 0.66 and 0.74, respectively). Significant improvement to quality of life was also observed with medium effect size (g = 0.53).Conclusions:There is now preliminary support for the use of an adaptation of an established group-based tCBT protocol for use with individuals. Implications and recommendations for future investigations are provided.

A comprehensive scheme for the objective upper body assessments of subjects with cerebellar ataxia

BackgroundCerebellar ataxia refers to the disturbance in movement resulting from cerebellar dysfunction. It manifests as inaccurate movements with delayed onset and overshoot, especially when movements are repetitive or rhythmic. Identification of ataxia is integral to the diagnosis and assessment of severity, and is important in monitoring progression and improvement. Ataxia is identified and assessed by clinicians observing subjects perform standardised movement tasks that emphasise ataxic movements. Our aim in this paper was to use data recorded from motion sensors worn while subjects performed these tasks, in order to make an objective assessment of ataxia that accurately modelled the clinical assessment.MethodsInertial measurement units and a Kinect© system were used to record motion data while control and ataxic subjects performed four instrumented version of upper extremities tests, i.e. finger chase test (FCT), finger tapping test (FTT), finger to nose test (FNT) and dysdiadochokinesia test (DDKT). Kinematic features were extracted from this data and correlated with clinical ratings of severity of ataxia using the Scale for the Assessment and Rating of Ataxia (SARA). These features were refined using Feed Backward feature Elimination (the best performing method of four). Using several different learning models, including Linear Discrimination, Quadratic Discrimination Analysis, Support Vector Machine and K-Nearest Neighbour these extracted features were used to accurately discriminate between ataxics and control subjects. Leave-One-Out cross validation estimated the generalised performance of the diagnostic model as well as the severity predicting regression model.ResultsThe selected model accurately (96.4%) predicted the clinical scores for ataxia and correlated well with clinical scores of the severity of ataxia (rho = 0.8, p < 0.001). The severity estimation was also considered in a 4-level scale to provide a rating that is familiar to the current clinically-used rating of upper limb impairments. The combination of FCT and FTT performed as well as all four test combined in predicting the presence and severity of ataxia.ConclusionIndividual bedside tests can be emulated using features derived from sensors worn while bedside tests of cerebellar ataxia were being performed. Each test emphasises different aspects of stability, timing, accuracy and rhythmicity of movements. Using the current models it is possible to model the clinician in identifying ataxia and assessing severity but also to identify those test which provide the optimum set of data.Trial registration Human Research and Ethics Committee, Royal Victorian Eye and Ear Hospital, East Melbourne, Australia (HREC Reference Number: 11/994H/16).

Transcutaneous Afferent Patterned Stimulation Therapy Reduces Hand Tremor for One Hour in Essential Tremor Patients.

Essential tremor (ET) patients often experience hand tremor that impairs daily activities. Non-invasive electrical stimulation of median and radial nerves in the wrist using a recently developed therapy called transcutaneous afferent patterned stimulation (TAPS) has been shown to provide symptomatic tremor relief in ET patients and improve patients’ ability to perform functional tasks, but the duration of tremor reduction is unknown. In this single-arm, open-label study, fifteen ET patients performed four hand tremor-specific tasks (postural hold, spiral drawing, finger-to-nose reach, and pouring) from the Fahn-Tolosa-Marin Clinical Rating Scale (FTM-CRS) prior to, during, and 0, 30, and 60 min following TAPS. At each time point, tremor severity was visually rated according to the FTM-CRS and simultaneously measured by wrist-worn accelerometers. The duration of tremor reduction was assessed using (1) improvement in the mean FTM-CRS score across all four tasks relative to baseline, and (2) reduction in accelerometer-measured tremor power relative to baseline for each task. Patients were labeled as having at least 60 min of therapeutic benefit from TAPS with respect to each specified metric if all three (i.e., 0, 30, and 60 min) post-therapy measurements were better than that metric’s baseline value. The mean FTM-CRS scores improved for at least 60 min beyond the end of TAPS for 80% (12 of 15, p = 4.6e–9) of patients. Similarly, for each assessed task, tremor power improved for at least 60 min beyond the end of TAPS for over 70% of patients. The postural hold task had the largest reduction in tremor power (median 5.9-fold peak reduction in tremor power) and had at least 60 min of improvement relative to baseline beyond the end of TAPS therapy for 73% (11 of 15, p = 9.8e–8) of patients. Clinical ratings of tremor severity were correlated to simultaneously recorded accelerometer-measured tremor power (r = 0.33–0.76 across the four tasks), suggesting tremor power is a valid, objective tremor assessment metric that can be used to track tremor symptoms outside the clinic. These results suggest TAPS can provide reductions in upper limb tremor symptoms for at least 1 h post-therapy in some patients, which may improve patients’ ability to perform tasks of daily living.

Association of serum allopregnanolone with restricted and repetitive behaviors in adult males with autism

Autism spectrum disorder (ASD) has been associated with imbalance between excitatory and inhibitory (E/I) neurotransmission systems, as well as with neuroinflammation. Sitting at the crossroads between E/I imbalance and neuroinflammation is a class of endogenous hormones known as neurosteroids. Current literature points to dysregulated steroid metabolism and atypical neurosteroid levels in ASD as early as in utero. However, due to the complexity of neurosteroid metabolomics, including possible sex differences, the impact of neurosteroids on ASD symptomatology remains unclear. In this study, we assessed neurosteroid levels and ASD symptom severity of 21 males with ASD and 20 full-scale-IQ-matched typically developing (TD) males, all aged 18–39. Using liquid chromatography-tandem mass spectrometry, concentrations of allopregnanolone, cortisol, dehydroepiandrosterone, progesterone, and testosterone were measured in saliva and serum. With the exception of cortisol’s, all neurosteroids’ concentrations were found to have ASD vs. TD group differences in distribution, where one group was normally distributed and the other non-normally distributed. Serum allopregnanolone levels in males with ASD were found to negatively correlate with clinician-rated measures of restricted and repetitive behavior measures (ADOS-2 RRB and ADI-R RRSB domain scores). Additionally, lower serum allopregnanolone levels were found to predict more negative camouflaging scores, which represent greater differences in self- and clinician-rated symptom severity, of both ASD symptomatology overall and repetitive behaviors in particular. Taken together, our findings demonstrate that in adult males with ASD, decreased serum allopregnanolone levels are associated with more severe restricted and repetitive behaviors and with less insight into the severity of these behaviors.

New method for quantification of severity of isolated scaphocephaly linked to intracranial volume

PurposeThe aim is to implement Utrecht Cranial Shape Quantificator (UCSQ) for quantification of severity of scaphocephaly and compare UCSQ with the most used quantification method, cranial index (CI). Additionally, severity is linked to intracranial volume (ICV).MethodsSinusoid curves of 21 pre-operative children (age < 2 years) with isolated scaphocephaly were created. Variables of UCSQ (width of skull and maximum occiput and forehead) were combined to determine severity. CI was calculated. Three raters performed visual scoring for clinical severity (rating of 6 items; total score of 12 represents most severe form). Pearson’s correlation test was used for correlation between UCSQ and visual score and between both CIs. ICV was calculated using OsiriX. ICV was compared to normative values and correlated to severity.ResultsMean UCSQ was 22.00 (2.00–42.00). Mean traditional CI was 66.01 (57.36–78.58), and mean visual score was 9.1 (7–12). Correlations between both traditional CI and CI of UCSQ and overall visual scores were moderate and high (r = − 0.59; p = 0.005 vs. r = − 0.81; p < 0.000). Mean ICV was 910 mL (671–1303), and ICV varied from decreased to increased compared to normative values. Negligible correlation was found between ICV and UCSQ (r = 0.26; p > 0.05) and between ICV and CI and visual score (r = − 0.30; p > 0.05 and r = 0.17; p > 0.05, respectively).ConclusionOur current advice is to use traditional CI in clinical practice; it is easy to use and minimally invasive. However, UCSQ is more precise and objective and captures whole skull shape. Therefore, UCSQ is preferable for research. Additionally, more severe scaphocephaly does not result in more deviant skull volumes.

Imagery-enhanced v. verbally-based group cognitive behavior therapy for social anxiety disorder: a randomized clinical trial.

Cognitive behavior therapy (CBT) is effective for most patients with a social anxiety disorder (SAD) but a substantial proportion fails to remit. Experimental and clinical research suggests that enhancing CBT using imagery-based techniques could improve outcomes. It was hypothesized that imagery-enhanced CBT (IE-CBT) would be superior to verbally-based CBT (VB-CBT) on pre-registered outcomes. A randomized controlled trial of IE-CBT v. VB-CBT for social anxiety was completed in a community mental health clinic setting. Participants were randomized to IE (n = 53) or VB (n = 54) CBT, with 1-month (primary end point) and 6-month follow-up assessments. Participants completed 12, 2-hour, weekly sessions of IE-CBT or VB-CBT plus 1-month follow-up. Intention to treat analyses showed very large within-treatment effect sizes on the social interaction anxiety at all time points (ds = 2.09-2.62), with no between-treatment differences on this outcome or clinician-rated severity [1-month OR = 1.45 (0.45, 4.62), p = 0.53; 6-month OR = 1.31 (0.42, 4.08), p = 0.65], SAD remission (1-month: IE = 61.04%, VB = 55.09%, p = 0.59); 6-month: IE = 58.73%, VB = 61.89%, p = 0.77), or secondary outcomes. Three adverse events were noted (substance abuse, n = 1 in IE-CBT; temporary increase in suicide risk, n = 1 in each condition, with one being withdrawn at 1-month follow-up). Group IE-CBT and VB-CBT were safe and there were no significant differences in outcomes. Both treatments were associated with very large within-group effect sizes and the majority of patients remitted following treatment.

The Unified Protocol compared with diagnosis-specific protocols for anxiety disorders: 12-month follow-up from a randomized clinical trial

ObjectiveTo examine whether the Unified Protocol (UP) remains equivalent to single-disorder protocols (SDPs) in the treatment of anxiety disorders at 12-month follow-up. MethodWe report results from the 12-month follow-up of a recent randomized equivalence trial [1]. Data are from 179 participants (55.31% female sex, 83.24% White, average age 30.66) who met criteria for a principal anxiety disorder and were randomized to either the UP or SDP conditions. Consistent with the parent trial, the primary outcome was principal diagnosis clinician severity rating (CSR) from the Anxiety Disorder Interview Schedule (ADIS). Secondary outcomes included anxiety, depression, and impairment. Missing data were accommodated using multiple imputation (10,000 imputed data sets) under a missing at random assumption. Equivalence between the UP and SDPs was tested using slope difference scores from latent growth models and 95% confidence interval of between-condition effect sizes. ResultsThe results indicated that the UP and SDP conditions remained equivalent with regard to principal diagnosis clinician severity rating at 12-month follow-up. In addition, there were no significant differences between conditions on secondary outcomes at 12-month follow-up. ConclusionsThe UP continues to yield outcomes comparable to SDPs at 12-month follow-up, and therefore provides a single intervention that can be used to treat the most commonly occurring psychiatric disorders with durable effects.

Effects of glucocorticoid and noradrenergic activity on implicit and explicit facial emotion recognition in healthy men

Autism spectrum disorder (ASD) has been associated with imbalance between excitatory and inhibitory (E/I) neurotransmission systems, as well as with neuroinflammation.

Symptom trajectories of early responders and remitters among youth with OCD

ObjectivesThis study examined the phenomenology and predictors of early response and remission among youth with obsessive-compulsive disorder (OCD) receiving cognitive-behavioral therapy (CBT). MethodsOne hundred and thirty-nine youth with a current primary diagnosis of OCD participated in this study. Participants received 10 sessions of CBT augmented by either placebo or d-cycloserine (DCS) as part of a randomized double-blind multi-site clinical trial. Early response and remission status were determined by clinician-rated global symptom improvement (CGI-I) and severity (CGI-S), respectively. ResultsAt the mid-treatment assessment, 45.3% of youth were early responders, and 28.1% were early remitters. At post-treatment assessment, 79.1% of youth were responders and 67.6% were remitters. Early response predicted a higher likelihood of post-treatment response and remission; early remission significantly predicted a higher likelihood of post-treatment remission. Bivariate logistic regressions showed that early response was predicted by lower baseline clinician-rated global severity (CGI-S) and lower depression severity; however, only depression severity remained a significant predictor in the multivariable logistic regression model. Furthermore, bivariate logistic regressions showed that early remission was predicted by lower baseline clinician-rated global severity (CGI-S), lower depression severity, and lower obsessive-compulsive symptom severity (CY-BOCS); however, only global severity remained a significant predictor in the multivariable logistic regression model. ConclusionsLower OCD and depression symptom severity predicted a greater likelihood of early treatment response and remission to CBT. Findings suggest that low OCD and depression symptom severity could serve as baseline characteristics to identify potential candidates for lower-intensity initial interventions in a stepped care approach. The modest predictive value of the variables examined suggests that additional factors could add to prediction of treatment response and remission.

The role of affect lability on tic severity and impairment in youth with Tourette's disorder

A common challenge for individuals with Tourette's Disorder and Persistent Tic Disorders (collectively referred to as TD) is emotion regulation, which underlies multiple co-occurring conditions and may contribute to both tic and non-tic related impairment. This study investigated the relationships between tic severity, impairment, and affect lability—a core component of emotion regulation.Participants were 75 youth with tic disorders and their caregivers, who completed an assessment to characterize tic severity, psychiatric comorbidities, functional impairment, family accommodation due to tics, and affect lability. Hierarchical regression models examined the contributions of affect lability on tic impairment, non-tic related impairment, and family accommodation.Youth with TD experienced greater levels of non-tic impairment relative to tic impairment across functional domains (d = 0.38 - .74). Regressions revealed that greater affect lability predicted both greater tic impairment and greater non-tic related impairment, even after controlling for clinician-rated tic severity. Exploratory analyses found that both affect lability and tic-related impairment uniquely contributed to family accommodation of tics, even after accounting for tic severity.While affect lability has received minimal attention in TD, it contributes to both tic and non-tic impairment among youth with TD. Strategies that enhance emotion regulation may have the potential to alleviate non-tic related impairment and improve family functioning for youth with TD.

Convergence between clinician‐rated and patient‐reported PTSD symptoms in a specialized outpatient service: The moderator role of gender

Posttraumatic stress disorder (PTSD) includes different symptoms: re-experiencing, avoidance of reminders and numbing, and hyperarousal. Although questionnaires are widely used, clinician-administered interviews provide a more comprehensive exploration of symptoms. Few studies examined the convergence between clinician-rated and patient-reported general severity and symptoms, with mixed findings. We explored the association between clinician-rated and patient-reported general severity and symptoms and the moderator role of gender in PTSD patients referred to a specialized outpatient service. The Clinician-Administered PTSD Scale and Davidson Trauma Scale were administered to 56 patients. Patients classified by clinicians as with higher avoidance/numbing symptoms and women classified with higher hyperarousal symptoms reported higher general severity. The assessment of the patients reporting high severity should focus on hyperarousal, particularly for women.
