An Initial Investigation of the Joint Classification of Hypomania- and Neurodevelopmental Disorder-Relevant Dimensions Within the Hierarchical Taxonomy of Psychopathology.

We examined hierarchical structural models of psychopathology in samples of (a) adults recruited online and screened based on psychopathology history (N = 429) and (b) undergraduates (N = 529) to inform classification of neurodevelopmental disorder (NDD)- and hypomania-relevant dimensions within the Hierarchical Taxonomy of Psychopathology (HiTOP). Results differed across samples in some ways, but converged to indicate that some NDD- and hypomania-relevant dimensions aligned closely with different HiTOP spectra. For example, some hypomania-relevant dimensions (e.g., affective lability) overlapped strongly with the internalizing spectrum, whereas others (e.g., self-perceived charisma) were reverse-indicators of detachment. Examination of cross-sectional and prospective correlates for emergent factors also was informative in some ways. This included NDD-relevant and disinhibited externalizing dimensions associating robustly with treatment seeking history and recent experiences of distress. These results provide initial insights into classifying NDD- and hypomania-relevant dimensions within the HiTOP and indicate a need for future research in this area.

Can dialectical behavior therapy skills group treat social anxiety disorder? A brief integrative review.

The purposes of this brief integrative review are to identify and critically evaluate recent work in the area of Dialectical Behavior Therapy-Skills Group (DBT-SG) for Social Anxiety Disorder (SAD) with suicidal ideation (SI) and to suggest further how DBT-based skills may be applied to cognitive maintenance factors of SAD. Accordingly, we first evaluate the relevance of DBT in treating SI in other disorders. Second, we evaluate the relationship between SI and SAD, providing considerations for the complexity of comorbid disorders and presentations. Finally, we extend this knowledge to discuss considerations for the use of DBT-SG skills to target specific etiological and maintenance elements of SAD, with a focus on four themes (interpersonal effectiveness, mindfulness, emotion regulation, and distress tolerance). Overall, we conclude that DBT-SG may prove beneficial in reducing SI and symptoms in SAD that impact social and emotional functioning.

A multisample demonstration of using the prolific platform for repeated assessment and psychometric substance use research.

The Prolific platform offers a potentially useful and efficient crowdsourcing option for repeated assessment substance use research, including for psychometric research requiring large samples. We present both (a) a series of practical recommendations for using Prolific and (b) data from multiple samples demonstrating Prolific's potential for efficiently collected repeated measures data. First, we present data from a 5-day daily diary protocol. We recruited a large sample (N = 321 at Day 1) screened for a history of self-identified mental health issues and weekly alcohol use. Participant adherence was good (82%) even without in-person contact. Alcohol use patterns conformed to theoretical expectations: Participants were more likely to drink on Fridays and Saturdays than other days, men drank more than women, and higher Alcohol Use Disorders Identification Test (AUDIT; Saunders et al., 1993) scores were associated with an increased likelihood of use and more overall drinking on a given day. Second, we present data from 429 Prolific participants screened for a history of mental health issues who completed assessments 2 weeks apart with strong retention (N = 377; 88%). We compare these data with the data from undergraduates (N = 529) to demonstrate Prolific's utility for conducting psychometrically oriented substance use research. Internal consistency estimates for measures from the Prolific data matched or exceeded those from the undergraduate data. Furthermore, measure scores showed strong temporal stability, and factor structures (e.g., AUDIT item-level structures) conformed to theoretical expectations. Collectively, these findings indicate that Prolific can be used successfully for repeated measures data collection. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
