Using data from the PCL-5 administered daily for 9 days, we (a) conducted item analysis of the PCL-5 using the graded response model to examine item characteristics (thresholds and discrimination parameters) and (b) examined differential item functioning (DIF) to evaluate whether the PCL-5 measured the PTSD latent trait identically across daily surveys (i.e., longitudinal measurement invariance). Methodologically, 256 trauma-exposed university students (<em>M</em>age = 21.01 ± 4.24; 85.8 % women; 41.0 % probable PTSD) completed the 20-item PCL-5 for 9 consecutive days. Across days, results indicated lower but acceptable discrimination for PCL-5 items 8 (traumatic amnesia), 16 (reckless or self-destructive behaviors), and 17 (hypervigilance). Further, 14 % of participants exhibited person misfit at least once across the 9 days. DIF analysis indicated that Item 2 (nightmares) exhibited DIF across days indicating potential bias; however, the effect sizes for DIF were negligible. In conclusion, the results broadly provide psychometric support for using the 20-item PCL-5 in intensive longitudinal studies. Future replication of study results across diverse and clinical populations could help to further strengthen these findings.</div></div>","PeriodicalId":48390,"journal":{"name":"Journal of Anxiety Disorders","volume":"116 ","pages":"Article 103079"},"PeriodicalIF":4.5,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite a growing body of research, comprehensive reviews on its presentation and assessment are limited and dated. This scoping review maps, synthesises and explores existing literature on the assessment measures and symptomatology of emetophobia. Its purpose is to inform future clinical practices by identifying reliable assessment instruments and facilitating more accurate diagnosis, treatment planning, and research comparisons. Five online databases (PubMed, SCOPUS, PsycINFO, Google Scholar, PsyArXiy) were searched using terms related to emetophobia. In total, 483 unique articles were located of which 38 were eligible for inclusion (35 described symptomatology; 3 described assessment measures). Among studies exploring symptoms, 17 were single case studies, 11 were cross-sectional surveys and 7 were other designs (e.g., case series, retrospective studies). Findings indicate that emetophobia is a multifaceted condition consisting of physical, psychological and behavioural symptoms. Avoidance behaviours are the most frequently reported symptom, described in 91 % of included literature. There is little research exploring the differences in child and adult symptom presentation which may result in misdiagnosis if an adult-centric criteria is applied. Two self-report questionnaires have been created and their psychometric properties assessed but, given numerous studies relied on longer, unvalidated assessment measures, these two measures appear to need further development. This review establishes that emetophobia is a complex and debilitating condition impacting multiple domains of life. Its findings will inform future research into the development and evaluation of tailored interventions targeting the specific presentation of emetophobia.</div></div>","PeriodicalId":48390,"journal":{"name":"Journal of Anxiety Disorders","volume":"116 ","pages":"Article 103076"},"PeriodicalIF":4.5,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decisions around pursuing reward in the presence of threat or avoiding threat at the cost of obtaining greater reward presents an approach-avoidance conflict (AAC). Although AAC is expected to be biased among trauma-exposed adults, especially those with posttraumatic stress disorder (PTSD), there have only been two prior behavioral investigations of AAC among adults with PTSD or experiencing PTSD symptoms. While greater levels of physical activity (PA) contribute to enhanced cognitive performance during reward-based decision-making tasks, it remains unknown whether greater PA also offers a protective effect or rather dampens the potential for greater AAC and sacrifice of reward in the presence of threat. The current study administered a trauma-related AAC behavioral task to trauma-exposed adults with varying PTSD symptom severity (N = 93), to examine potential interactive relationships between PTSD symptom severity, PA, and AAC decision-making under threat. The task involved a total of 150 trials and was divided into two phases: congruent (the option with the highest probability of a positive point outcome was also the option that was least likely to result in the presentation of a trauma-related image), and conflict (the option with the highest probability of a positive point outcome was also the option that was most likely to result in the presentation of a threat-related image). Results from linear mixed effects models revealed that PA moderated the relationship between PTSD symptom severity and AAC, as we observed a positive relationship between PTSD symptom severity and AAC for lower PA volume (i.e., greater conflict), and a more negative relationship between PTSD symptom severity and AAC as PA volume increased (i.e., less conflict). These results suggest that greater PA may promote a greater propensity to engage in goal-directed behavior and seek reward in the presence of threat in those with greater PTSD symptom severity.</div></div>","PeriodicalId":48390,"journal":{"name":"Journal of Anxiety Disorders","volume":"116 ","pages":"Article 103075"},"PeriodicalIF":4.5,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the Clinical Global Impression (CGI) scales and diagnostic interviews as benchmark measures, several thresholds for the 6-item PARS were estimated using data from 904 youth with anxiety disorders, of which 36 % had an autism diagnosis.

Scores of 0–10 after treatment accurately defined full and partial remission, and scores of 0–5 defined full remission.
