Race/ethnicity, sex, and age differences in pediatric SCAT-5 concussion symptoms

Objective To examine sociodemographic differences in concussion symptom reporting, among young children by race/ethnicity, sex, and age at initial presentation to guide potential interventions for children from different backgrounds. Method Participants were elementary-age children (ages 5 to 12 years; n = 392) who sustained a concussion within 30 days of specialty concussion clinic visit. Independent variables were self-defined race/ethnic group, participants’ sex, and age. Dependent variables were number and severity of 22 post-concussion symptoms as measured by the Sport Concussion Assessment Tool5® (SCAT-5) Symptom Evaluation. Results Analyses of variance (ANOVAs) showed no differences in reporting of symptoms across race/ethnic or age groups. There was no interaction between race/ethnic, sex and age groups. Females in this sample reported a greater number and severity of concussion symptoms than males. Conclusions Concussion symptom endorsement on the SCAT-5 Symptom Evaluation did not appear to be affected by race/ethnicity or age. However, consistent with existing literature, females reported higher endorsement of concussion symptoms than males and therefore may merit special consideration in evaluation of symptoms. Future research should examine the intersection of other sociodemographic variables with race/ethnicity and should consider the influence of respondent (child vs. parent) in studies of this age cohort.

Negative Emotion (dys)regulation Predicts Distorted Time Perception: Preliminary Experimental Evidence and Implications for Psychopathology.

Accurate time perception is crucial to daily life but vulnerable to interference, particularly through negative affect, which dilates individuals' sense of time passing. Regulation strategies like rumination, and disorders like borderline personality disorder (BPD), are linked to time distortion, yet their interrelationships remain untested. We investigated whether rumination and BPD symptoms increase time dilation in negative affective states to understand the clinical implications of time distortion. In an online pilot study, we tested whether negative affect (NA) predicts subjective time perception and explored how rumination, BPD symptoms, and their interaction predicted time perception using a between-subjects online experimental mood induction. Adult participants (Ncombined = 760) were recruited from Prolific Academic and a large, Midwestern U.S. university. State NA and increased BPD features predicted increased time dilation. The role of trait-level rumination was nuanced, with individuals low in BPD symptoms and elevated trait rumination exhibiting reduced time dilation in response to NA. Conversely, those with elevated rumination and BPD symptoms reported increased time dilation in the neutral condition. Findings offer foundational evidence of NA and rumination's roles in time dilation for individuals across levels of BPD symptom endorsement. Subsequent replication and extension could flesh out these relationships and inform psychotherapeutic treatment targets.

A - 92 Association of the Grit Scale with Cognitive/Emotional Symptom Endorsement in Older Former College Athletes

Abstract Objective The Grit Scale is a validated measure of trait-level perseverance, often linked with resilience, and has been associated with better cognition and psychological well-being in older adults. As the ability to respond positively to setbacks is essential for a successful athlete, investigation of the Grit Scale in former athletes may prove beneficial for further understanding the effect of resilience and its relation to brain health and psychological well-being. Method Former college athletes (N = 678, 45.9% female) aged 50–87 (m = 61.44) from the College Level Aging Athlete Study (CLEAATS) completed the Grit Scale, Patient Health Questionnaire (PHQ-8), Generalized Anxiety Disorder Scale (GAD-7), Cognitive Function Instrument (CFI), and the Telephone Interview for Cognitive Status-Modified (TICS-m). Pearson’s partial correlations (r) were used to determine the relationship between scores on these measures, controlling for age and education. Results Pearson partial correlations between Grit Scale scores and scores from the other measures were modest but statistically significant: PHQ-8 (r = −0.342, p < 0.001), GAD-7 (r = −0.259, p < 0.001), CFI (r = −0.316, p < 0.001), and TICS-m (r = 0.101, p = 0.008). Conclusions Comparison of the Grit Scale with PHQ-8, GAD-7, CFI, and TICS-m indicated that greater trait-level perseverance correlated with better cognitive and emotional functioning in former college athletes. Results emphasize the need to further evaluate perseverance/resilience and its value for understanding brain health and psychological well-being in athletes and former athletes.

B - 13 Effects of Individual and Community-Level Adverse Childhood Experiences and Current Psychopathology among Monolingual Spanish-Speaking Adult Neuropsychology Referrals

Abstract Objective The link between adverse childhood experiences (ACEs) and higher rates of psychopathology in adulthood has been well-established, though far less analogue research has examined this relationship among Latinx patients. This study assessed the relationship between ACEs and symptoms of anxiety, depression, and perceived stress among monolingual Spanish-speaking neuropsychology referrals. Method Data were culled from 27 adult neuropsychology referrals (mean age = 61.70; mean education = 8.59) neuropsychological referrals administered the ACE Questionnaire, Beck Depression Inventory (BDI-II), Geriatric Depression Scale (GDS), Beck Anxiety Inventory (BAI), and Perceived Stress Scale (PSS). Linear regression analyses examined the effect of exposure to individual (e.g., emotional, physical, sexual abuse, neglect, domestic violence) and community-level ACEs on depression, anxiety, and perceived stress symptom endorsement. Results Endorsement of more individual ACEs predicted higher levels of anxiety (R2 = 0.281; p = 0.009) and depression (R2 = 0.127; p = 0.075) symptoms, but not perceived stress levels (R2 = 0.037; p = 0.365. By contrast, endorsement of more community-level ACEs marginally predicted higher anxiety symptoms (R2 = 0.124; p = 0.071), but not depression symptoms (R2 = 0.020; p = 0.568) or perceived stress levels (R2 = 0.045; p = 0.319). Conclusions Experiencing more individual-level ACEs predicted greater anxiety and, to a lesser extent, depressive symptoms, whereas community-level ACEs did not predict similar levels of endorsement of active psychopathology among monolingual Spanish-speaking adults referred for neuropsychological evaluation. Findings emphasize the need of neuropsychologists to consider routinely assessing patient’s childhood trauma history and current psychopathology symptoms during evaluation to improve diagnostic accuracy and recommendations for Latinx patients.

A - 35 Effects of Childhood Trauma Exposure on Psychological Symptom Endorsement among Adult ADHD Referrals

Abstract Objective Adults with attention-deficit/hyperactivity disorder (ADHD) are more likely to have childhood trauma exposure. Trauma exposure evaluations are not always standard practice for adult ADHD evaluations, but personality inventories like the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) are more commonly used to differentiate neurodevelopmental symptoms from psychiatric disorders. This study assessed the impact of childhood trauma exposure on MMPI-2-RF profiles among adults referred for ADHD evaluation. Method Cross-sectional data from 222 patients referred for neuropsychological evaluation for attention concerns and administered the Adverse Childhood Experiences (ACE) Checklist and MMPI-2RF were examined. Patients were racially diverse with a Mage 29.15 (SD = 7.63) and Meducation 16.15 years (SD = 2.13). Patients were divided into low (0–3 ACEs) and high (>3 ACEs) ACE groups. ACEs groups’ MMPI-2RF Restructured Clinical (RC) scale scores were compared via multivariate analyses of variance (MANOVAs) for the overall sample and subsample of those who ultimately received an ADHD diagnosis. Results The sample had 52% low ACEs/48% high ACEs, and 65% ADHD diagnosis/35% non-ADHD diagnosis. Overall, there was a significant multivariate effect (Wilks Λ =0.812; F(9,212) = 5.45, p < 0.001; np2 = 0.188); those with high ACE scores had significantly higher RC1, RC4, RC6, RC7, and RC8 scores. Significant MANOVA effects remained when the sample with subdivided. Across ADHD and non-ADHD subgroups, significantly higher RC4 and RC6 scores were consistent. Conclusions Exposure to childhood trauma had a significant impact on the MMPI-2-RF profile of adults being evaluated for ADHD. Screening for trauma exposure should be incorporated into standard neuropsychological batteries to inform the interpretation of personality inventories used to differentiate psychopathology.

B - 30 Influence of Military Blast Exposure on Subjective Post-Concussion Symptom Reporting

Abstract Objective Repeated subconcussive blast exposure associated with explosive breaching, mortars, and shoulder-fired artillery weapons is commonly seen in the military/veteran population and has been found to contribute to adverse neurological outcomes; however, the extent is not fully understood. The aim of this study was to assess the effects of blast exposure during military or other training exercises on neurobehavioral symptom endorsement. Method Cross-sectional data from 48 nonclinical post-deployment Operation Enduring Freedom/Operation Iraqi Freedom veterans prospectively-recruited for a study examining posttraumatic stress and cognitive correlates at an urban VA Medical Center were examined (M age = 36.02; SD = 6.12; M years of education = 14.94; SD = 1.84). The sample was 96% male, 41% White, 39% Black, 4% Asian, and 16% Other. The Neurobehavioral Symptom Inventory (NSI) was used to assess self-reported vestibular, somatosensory, cognitive, and affective post-concussion symptoms, and the Boston Assessment of Traumatic Brain Injury-Lifetime semi-structured clinical interview assessed military-related blast exposure. Results There was a significant difference in neurobehavioral symptoms based on blast exposure, F(4,43) = 3.49, p = 0.015; Wilk’s Λ = 0.755, partial η2 = 0.25. Follow-up analyses showed that veterans with history of blast exposure endorsed significantly higher levels of somatosensory (F(1,47) = 7.69, p = 0.008, η2 = 0.143); affective (F(1,47) = 12.66, p < 0.001, η2 = 0.216); cognitive (F(1,47) = 5.97, p = 0.018, η2 = 0.115); and vestibular (F(1,47) = 7.21, p = 0.010, η2 = 0.136) post-concussive symptoms on the NSI compared to those without history of military blast exposure. Conclusion Veterans with blast exposure during military service reported significantly greater levels of post-concussion symptoms. This demonstrates the need to assess history of blast exposure, implement prevention measures through safeguards and decreased exposure when possible, and establish treatment modalities to improve outcomes.

Improving posttraumatic stress disorder assessment in young children: comparing measures and identifying clinically-relevant symptoms in children ages six and under

Young children exposed to trauma are vulnerable to developing posttraumatic stress disorder (PTSD). Although experts agree on the importance of tailoring PTSD assessments to be developmentally-appropriate for young children, there is little research on which assessment methods best identify clinically significant symptomatology in this difficult-to-assess population. Two competing models for assessing PTSD have been proposed by the DSM-5 and ICD-11. This study compared a DSM-5 measure to an ICD-11 measure in young children (ages 1–6) exposed to a natural disaster. The measures identified similar rates of PTSD in children; however, diagnostic agreement between the measures was low (31–36%). Both PTSD measures were associated with actual and perceived life threat, functional impairment, and comorbid psychopathology. PTSD symptom and cluster endorsement rates were also binned by age and compared to functional impairment to identify commonly-reported and highly impairing symptoms in trauma-exposed young children, as potential candidates for inclusion in future revisions of diagnostic criteria. Across age ranges, increased clinginess post-trauma was the most commonly reported symptom and was associated with functional impairment. Arousal symptoms (startle, hypervigilance) and Re-experiencing symptoms (nightmares) also emerged as relevant for young children. Findings may contribute to efforts to improve assessment for PTSD in young children.

Assessing self-reported prolonged grief disorder with "clinical checks": A proof of principle study.

Psychological assessment is commonly conducted using either self-report measures or clinical interviews; the former are quick and easy to administer, and the latter are more time-consuming and require training. Self-report measures have been criticized for producing higher estimates of symptom and disorder presence relative to clinical interviews, with the assumption being that self-report measures are prone to Type 1 error. Here, we introduce the use of "clinical checks" within an existing self-report measure. These are brief supplementary questions intended to clarify and confirm initial responses, similar to what occurs in a clinical interview. Clinical checks were developed for the items of the International Grief Questionnaire (IGQ), a self-report measure of ICD-11 prolonged grief disorder (PGD). Data were collected as part of a community survey of mental health in Ukraine. Individual symptom endorsements for the IGQ significantly decreased with the use of clinical checks, and the percentage of the sample that met the ICD-11 diagnostic requirements for PGD fell from 13.6% to 10.2%, representing a 24.8% reduction in cases. The value and potential broader application of clinical checks are discussed.

Ethno-racial differences in depressive symptom endorsement: Evaluation of brief forms of the Geriatric Depression Scale in older adults.

Depression among older adults is a pressing public health concern, necessitating accurate assessment tools. The Geriatric Depression Scale (GDS) offers a brief and efficient means of screening depressive symptoms, yet its performance across ethno-racial groups remains understudied. This study aimed to compare the ability of various brief forms of the GDS to detect depressive symptoms and to assess potential ethno-racial differences in symptom endorsement among White, Black/African-American, and American Indian/Alaska Native older adults. Data were obtained from the Wisconsin Alzheimer's Disease Research Center (ADRC) clinical cohort, comprising 555 cognitively healthy individuals at risk for dementia. We used participants' baseline data for this cross-sectional analysis. Depressive symptoms were assessed using multiple brief forms of the GDS, derived from a systematic review and meta-analysis. We examined internal consistency and correlations with global Clinical Dementia Rating (CDR) scores. We conducted Kruskal-Wallis tests and post hoc pairwise comparisons to assess ethno-racial group differences in symptom endorsement. Descriptive statistics revealed a predominance of female and White participants, with notable representation from Black and American Indian/Alaska Native groups. All GDS versions demonstrated moderate to high internal consistency. Significant positive correlations were observed between GDS scores and global CDR scores. Ethno-racial group differences in depressive symptom endorsement were evident, with Black participants consistently reporting higher levels of symptoms across most GDS versions. However, American Indian/Alaska Native participants endorsed significantly fewer symptoms than Black participants in one GDS version. The study highlights the importance of considering ethno-racial differences in depressive symptomatology when assessing older adults. While the GDS demonstrates overall reliability, variations in symptom endorsement across different ethno-racial groups underscore the need for culturally sensitive assessment tools and interventions. Future research should further explore these group differences and develop tailored approaches to depression screening and treatment in diverse older adult populations.

Using item response theory to identify key symptoms of insomnia in a sample of university students with probable eating disorders

PurposeResearchers have theorized that interactions between appetitive and circadian disruptions result in increased eating disorder (ED) symptoms and insomnia. However, it is unclear how specific insomnia symptoms present among people with EDs and if the latent structure of insomnia in this population is similar to that of people with insomnia disorder.MethodsWe conducted a secondary analysis of data collected on ED and insomnia symptoms using a subset of students (N = 547; 79.52% female) with probable EDs at a large Midwestern American university. Item response theory (IRT) for polytomous items was performed to identify item difficulty, discrimination, and information parameters for the Insomnia Severity Index (ISI). IRT parameters were compared to those established in a 2011 study of people diagnosed with insomnia disorder by Morin and colleagues.ResultsClinically significant insomnia symptoms were common among students with ED pathology and symptom endorsement for each ISI item ranged from 40.77 to 86.65%. ISI items assessing insomnia-related impairment and distress showed better discriminative capacities and had higher item information than items assessing sleep behavior alterations (i.e., difficulties falling asleep, difficulties maintaining sleep, waking too early). Item discrimination was largely similar among the ED sample compared to previous IRT analyses in an insomnia disorder sample.ConclusionInsomnia symptoms are common among university students with probable EDs and similar to those reported by people with insomnia disorder. When considering insomnia assessment, items assessing sleep behaviors alone are likely inadequate to provide information about insomnia severity among people with EDs.Level VEvidence obtained from a cross-sectional descriptive study.

Predictors of National Institute on Alcohol Abuse and Alcoholism (NIAAA) Alcohol Recovery among Individuals in Alcohol Treatment: Implications for Social Work.

The National Institute on Alcohol Abuse and Alcoholism's (NIAAA) definition of alcohol use disorder (AUD) recovery stipulates two criteria: remission from DSM-5 AUD and cessation of heavy drinking. Importantly, these criteria allow for consideration of nonabstinent alcohol treatment outcomes. However, researchers have yet to assess potential predictors of the NIAAA recovery outcome. The current study examined associations between mental health and coping predictors of NIAAA recovery status in an AUD treatment sample. At baseline (BL) and end-of-treatment (EOT) research interviews in a clinical trial, participants (N = 118) completed questionnaires assessing alcohol dependence, mental health, and confidence levels in reducing heavy drinking, as well as alcohol use and DSM-5 AUD symptom endorsement. Logistic regression models tested the associations between chosen predictors and the odds of achieving NIAAA recovery. Twenty-four percent of individuals (n = 28) met both criteria for NIAAA recovery at EOT. Higher levels of BL state anxiety and anxiety sensitivity predicted lower odds of achieving NIAAA recovery, while greater confidence to reduce heavy drinking predicted increased odds of NIAAA recovery. Social workers are encouraged to continue assessing and addressing mental health in AUD treatment to help individuals with alcohol problems achieve their AUD recovery goals.

Unraveling PTSD: Symptom cluster change during and 1 year after veterans' residential PTSD treatment.

Although treatment of posttraumatic stress disorder (PTSD) is effective in reducing symptom severity, remission rates are low. One potential underlying reason for treatment ineffectiveness is differential response of specific PTSD symptom clusters. Using data from a national Veterans Affairs (VA) residential PTSD treatment cohort, we conducted a longitudinal study to examine changes in Diagnostic and Statistical Manual of Mental Disorders, fifth edition PTSD symptom clusters from admission to 1-year follow-up. PTSD symptom data were analyzed from a national cohort of veterans who completed VA PTSD residential treatment between October 2019 and September 2020 (n = 1,648; 13% women; median age 44.2 years). Endorsement (%) and severity (M[SD]) of PTSD clusters and individual symptoms were compared at admission, discharge, 4-month and 1-year follow-ups. Large magnitude reductions in all four PTSD symptom clusters were observed from admission to discharge and both follow-ups; however, endorsement of all symptom clusters remained high. Intrusions (Cluster B) were the most highly endorsed at discharge and follow-up, whereas avoidance symptoms (Cluster C) were the least highly endorsed. Differential patterns of change were observed among the 20 individual PTSD symptoms; for example, flashbacks decreased during treatment, but increased to near admission levels by 1-year postdischarge. Results suggest that intrusive symptoms may be more resistant to residential treatment for PTSD and contribute to lower likelihood of treatment success. Future work is needed to examine differential treatment response for PTSD clusters, to inform the improvement of current and creation of novel treatment interventions, and to better address intrusive symptoms to maximize PTSD treatment gains.

A - 57 Relationship between Exercise Participation and Cognitive/Emotional Symptom Endorsement in Older Former College Athletes

Abstract Purpose Exercise participation has been associated with improved physical health, cognition, and psychological well-being as well as reduced risk for chronic illness and mortality. The effects of exercise participation in former athletes are less understood; this study investigated the relationship between current exercise participation and cognitive/emotional symptoms in former college athletes. Method Former college athletes aged 50–87 (N = 597, 44.2% female) completed the College Level Aging Athlete Study (CLEAATS) survey including the Patient Health Questionnaire (PHQ-8), Generalized Anxiety Disorder (GAD-7), Cognitive Function Instrument (CFI), Telephone Interview for Cognitive Status-Modified (TICS-m), and self-reported weekly exercise involvement, classified as aerobic exercise (e.g., jogging/cycling), anaerobic exercise (e.g., weightlifting), and “other wellness activities”(e.g., yoga/meditation). Four multiple linear regression models investigated whether current exercise participation predicted mood and cognition, adjusting for demographic factors. Results Overall models for PHQ-8 [F(6,590) = 8.87, p < 0.001], GAD-7 [F(6,590) = 4.87, p < 0.001], CFI [F(6,590) = 3.45, p = 0.002], and TICS-m [F(6,590) = 15.99, p < 0.001] were significant. Individually, aerobic exercise was a significant predictor of PHQ-8 (b = −0.35, p < 0.001), GAD-7 (b = −0.18, p = 0.007), CFI (b = −0.12, p = 0.021), and TICS-m (b = 0.18, p = 0.022) scores, such that more exercise predicted lower emotional/cognitive difficulties. Engagement in “other wellness activities”was significantly associated with higher TICS-m (b = 0.18, p = 0.024) scores. Anaerobic exercise was not a significant predictor in any model. Conclusions Consistent with research in other populations, participation in aerobic exercise predicted better cognitive/emotional functioning in former college athletes. Involvement in other forms of exercise did not consistently predict greater functioning, though “other wellness activities”was associated with better objective cognition. Results emphasize the importance of recommending aerobic exercise for former athletes.

Associations Between PTSD Features and Firearm Ownership and Storage: Results From the PRImary Care Screening Methods (PRISM) Study.

Veterans and active duty service members are significantly more likely to die by suicide using firearms compared to the general population. Not-secure firearm storage (e.g., keeping guns loaded/in an unlocked location) is associated with greater risk for suicide and a third of veteran firearm owners store at least 1 personal firearm unsecured. Veterans and active duty service members are also significantly more likely to be diagnosed with posttraumatic stress disorder (PTSD) than the general population. Symptoms of PTSD are divided into 4 criteria: reexperiencing, avoidance, negative affect, and hyperarousal. Research has suggested that endorsement of hyperarousal symptoms is positively associated with unsecure firearm storage and that avoidance symptoms might be negatively associated with unsecure storage practices. The present study examined the relationship between self-reported firearm ownership and storage practices among each item from the Primary Care PTSD Screening for DSM-IV-TR (PC-PTSD-IV) to explore associations between PTSD features and firearm ownership and storage. Participants were recruited from primary care clinics across 5 military installations in the United States as part of a larger study (Mage = 45.4, SD = 16.9). Among participants (n = 2,685), most of our sample identified as male (51.3%) and white (67.3%) with 61.6% currently serving in the military, 16.8% retirees, and 21.6% family members. PTSD symptoms were assessed using the PC-PTSD-IV and a quarter met the clinical threshold for PTSD. Binomial and multinomial logistic regression analyses were used. Among completed responses, 989 (38.1%) people reported owning guns; among gun owners, 386 (39.0%) reported that they were loaded, and 352 (35.6%) reported they were loaded and unlocked. Endorsement of specific items on the PC-PTSD-IV, including those specific to hyperarousal and avoidance, was not significantly associated with storing firearms loaded and/or in nonsecure locations when controlling for military service. Non-responses to items around firearm storage practices were significantly associated with those individuals meeting the clinical threshold for PTSD according to the PC-PTSD-IV and participants currently serving had higher odds of storing at least 1 personal firearm loaded and both loaded and unlocked. Results from our study highlight similarities and departures from the previous literature on the connection between PTSD and non-secure firearm storage practices. Further research may examine (1) the relation between PTSD symptoms and firearm storage between active duty service members, retirees, and family members and (2) whether non-response to items regarding firearm ownership is systematic.

Sociodemographic correlates of parent and youth-reported eating disorder symptoms in the Adolescent Brain Cognitive Development Study.

Eating Disorders (EDs) often start in adolescence, though ED-related concerns in diverse youth samples remain understudied. We leveraged data from the Adolescent Brain Cognitive Development (ABCD) Study to identify the prevalence of parent- and youth-reported ED symptoms and their sociodemographic characteristics. Data were drawn from baseline (ages 9-11 years, n=11,868) and 2-year follow-up (ages 11-14 years; n=10,908) from the ABCD Study. A tetrachoric factor analysis summarized clusters of ED symptoms, which were compared between parent and youth reports and across sociodemographic variables. Three factors emerged reflecting "weight distress", "weight control", and "binge eating" (prevalence range: 1.5-7.3%). Symptoms loaded onto similar factors between reporters. Rates of symptom endorsement were similar between sexes, with disproportionately higher endorsement rates for youth who self-identified as sexual minority, Hispanic, Black, or Mixed race participants, and those from a disadvantaged socioeconomic background, compared to the reference ABCD sample. Youth and parent reports at 2-year showed ~12% overlap. ED-related concerns among historically understudied racial and sexual minority groups call for greater attention to the detection and treatment of these symptoms in these groups. Applying a transdiagnostic approach to ED symptoms can inform effective detection and intervention efforts.

Latent Profiles of Co-occurring Sexual Problems and Posttraumatic Stress Symptoms Among Young Women Exposed to Sexual Violence.

Sexual dysfunctions (SDs) have been noted to occur following exposure to sexual violence although how these conditions covary with other mental health conditions, particularly posttraumatic stress disorder symptoms (PTSS), is relatively understudied. The current study examined patterns of co-occurring SDs and PTSS in a sample of 328 college-aged, female-identified survivors of adolescent/early adulthood sexual assault (ASA). Latent profile analysis was used to examine patterns of symptom endorsement of various types of SDs and PTSS at the symptom cluster level. Four profiles were identified: asymptomatic (41.2% of sample), sexually distressed + intrusions (24.7%), co-occurring (21%), and PTSS (13.1%). Profiles were compared to one another on various characteristics of sexual assault and social reactions from others following assault disclosure. Results indicated that those in the co-occurring symptom and PTSS profiles reported more severe ASA and more unsupportive social responses relative to the sexually distressed + intrusions and asymptomatic profiles. The asymptomatic profile was significantly less likely to have experienced rape relative to the other three profiles and was less likely to report instances where a close other treated them in a negative manner following assault disclosure. Results are discussed in light of mental health needs for young women who have experienced ASA, with implications discussed for future research and clinical services for university students.

Developmental changes in the endorsement of psychotic-like experiences from middle childhood through young adulthood

BackgroundChildren tend to endorse psychotic-like experiences (PLEs) at higher rates than adults, although little is known about how specific symptom endorsement changes across the span of development. Here we take an observational approach to examine trends in PLE endorsement by age in two non-clinical samples: one of school-aged children and another of late adolescents and early adults. MethodsProdromal Questionnaire-Brief (child and adult versions) responses were investigated in individuals ages 9–13 (n = 11865) and 16–24 (n = 3209) from the Adolescent Brain and Cognitive Development Study (ABCD) and the Multisite Assessment of Psychosis-risk Study (MAP), respectively. Item-level endorsement and distressing item frequencies were examined by age throughout both cohorts. ResultsUnusual perceptual experiences were generally endorsed more heavily in childhood, while other PLEs were endorsed in adolescents and adults up to 4.8 times more frequently than in children. Additionally, certain experiences were endorsed by as many as 73 percent of the older sample. ConclusionsConsiderations for the measurement of PLEs in childhood and adolescence are underscored. Findings from these two samples provide a window into the course of these PLEs and may serve as a scaffold for future research investigating normative versus risk-related experiences during development.

Measurement Properties of the Activities-Specific Balance Confidence Scale in Adults From the General Population With Concussion: A Report From the Toronto Concussion Study

ObjectiveThe aim of this study was to establish the internal consistency and construct validity of the Activities-specific Balance Confidence (ABC) Scale and ABC-6 in adults from the general population with concussion. DesignProspective analysis. SettingOutpatient concussion care clinic. ParticipantsAdults from the general population with concussion referred to a concussion care clinic within 7 days of injury (N=511). InterventionsNot applicable. Main Outcome MeasuresBalance confidence was assessed with the Activities-specific Balance Confidence (ABC) Scale and the ABC-6. Concussion symptoms were characterized using the Sport Concussion Assessment Tool version 5 (SCAT5) symptom checklist. Instrumented measures of balance and gait included center of pressure velocity and double support time, respectively. Balance was also assessed using the mBESS. ResultsThe ABC and ABC-6 were strongly correlated (ρ=0.980, P<.001). Cronbach α for ABC and ABC-6 was 0.966 and 0.940, respectively. Factor analysis verified the existence of 2 components of the ABC, 1 including all items of the ABC-6 as well as 3 additional items. ABC and ABC-6 were moderately significantly correlated with SCAT5 symptom number, severity, and symptom domain (ρ=−0.350 to −0.604). However, correlations between ABC and ABC-6 with instrumented measures of balance and gait were not statistically significant, except for double support time during dual-task gait with ABC-6 (ρ=−0.218). ConclusionsIn community-dwelling adults with concussion, the ABC and ABC-6 have good internal consistency. Convergent validity is stronger for symptom endorsement measures within SCAT5 domains, which has a similar construct (subjectivity) to balance confidence. Both the ABC and ABC-6 are valid measures of balance self-efficacy in adults from the general population with concussion. The ABC-6 may be a useful tool for characterizing the effect of concussion on perceptions of the ability to perform functional tasks that challenge balance and mobility.

Listening to Black Pregnant and Postpartum People: Using Technology to Enhance Equity in Screening and Treatment of Perinatal Mental Health and Substance Use Disorders.

Perinatal mood and anxiety disorders (PMADs), perinatal substance use disorders (PSUDs), and intimate partner violence (IPV) are leading causes of pregnancy-related deaths in the United States. Screening and referral for PMADs, PSUDs and IPV is recommended, however, racial disparities are prominent: Black pregnant and postpartum people (PPP) are less likely to be screened and attend treatment compared to White PPP. We conducted qualitative interviews to better understand the experience of Black PPP who used a text/phone-based screening and referral program for PMADs/PSUDs and IPV-Listening to Women and Pregnant and Postpartum People (LTWP). We previously demonstrated that LTWP led to a significant reduction in racial disparities compared to in-person screening and referral, and through the current study, sought to identify facilitators of PMAD/PSUD symptom endorsement and treatment attendance. Semi-structured interviews were conducted with 68 Black PPP who were or had been pregnant within the last 24 months, and who either had or did not have a PMAD or PSUD. Participants were enrolled in LTWP and provided feedback on their experience. Using a grounded theory approach, four themes emerged: usability, comfort, necessity, and recommendations. Ease of use, brevity, convenience, and comfort in discussing mental health and substance use via text were highlighted. Need for a program like LTWP in Black communities was discussed, given the reduction in perceived judgement and access to trusted information and resources for PMADs/PSUDs, which may lessen stigma. These qualitative findings illuminate how technology-based adaptations to behavioral health screening and referral can reduce perceived negative judgment and facilitate identification and referral to treatment, thereby more adequately meeting needs of Black PPP.

Identifying Depression Subtypes and Investigating their Consistency and Transitions in a 1-Year Cohort Analysis

Introduction Major Depressive Disorder (MDD) is a complex mental health condition characterized by a wide spectrum of symptoms. According to the Diagnostic Statistical Manual 5 (DSM-5) criteria, patients can present with up to 1,497 different symptom combinations, yet all receive the same MDD diagnosis. This diversity in symptom presentation poses a significant challenge to understanding the disorder in the wider population. Subtyping offers a way to unpick this phenotypic diversity and enable improved characterization of the disorder. According to reviews, MDD subtyping work to date has lacked consistency in results due to inadequate statistics, non-transparent reporting, or inappropriate sample choice. By addressing these limitations, the current study aims to extend past phenotypic subtyping studies in MDD.Objectives(1) To investigate phenotypic subtypes at baseline in a sample of people with MDD;(2) To determine if subtypes are consistent between baseline 6- and 12-month follow-ups; and(3) To examine how participants move between subtypes over time.Methods This was a secondary analysis of a one-year longitudinal observational cohort study. We collected data from individuals with a history of recurrent MDD in the United Kingdom, the Netherlands and Spain (N=619). The presence or absence of symptoms was tracked at three-month intervals through the Inventory of Depressive Symptomatology: Self-Report (IDS-SR) assessment. We used latent class and three-step latent transition analysis to identify subtypes at baseline, determined their consistency at 6- and 12-month follow-ups, and examined participants’ transitions over time.ResultsWe identified a 4-class solution based on model fit and interpretability, including (Class 1) severe with appetite increase, (Class 2), severe with appetite decrease, (Class 3) moderate, and (Class 4) low severity. The classes mainly differed in terms of severity (the varying likelihood of symptom endorsement) and, for the two more severe classes, the type of neurovegetative symptoms reported (Figure 1). The four classes were stable over time (measurement invariant) and participants tended to remain in the same class over baseline and follow-up (Figure 2).Image:Image 2:Conclusions We identified four stable subtypes of depression, with individuals most likely to remain in their same class over 1-year follow-up. This suggests a chronic nature of depression, with (for example) individuals in severe classes more likely to remain in the same class throughout follow-up. Despite the vast heterogeneous symptom combinations possible in MDD, our results emphasize differences across severity rather than symptom type. This raises questions about the meaningfulness of these subtypes beyond established measures of depression severity. Implications of these findings and recommendations for future research are made.Disclosure of Interest C.
