Validity of Adolescent and Parent Reports on the Six-Item ADHD Self-Report Scale (ASRS-6) in Clinical Assessments of Adolescent Social Anxiety

Adolescents experiencing social anxiety often experience co-occurring attention-deficit/hyperactivity disorder (ADHD) symptoms. Yet, assessing for social anxiety poses challenges given the already time-consuming task of distinguishing social anxiety from other commonly co-occurring internalizing conditions (e.g., generalized anxiety, major depression). Assessors need short screening devices to identify socially anxious adolescents in need of intensive ADHD assessments. A six-item version of the ADHD Self-Report Scale (ASRS-6) was originally developed to identify adults who likely meet diagnostic criteria for ADHD, but its psychometric properties have yet to be examined among adolescents. We tested the psychometric properties of the ASRS-6 when administered in clinical assessments for adolescent social anxiety. Eighty-nine 14–15 year old adolescents and their parents (67.4% female; 62.1% African American; 30 Clinic-Referred; 59 Community Control) completed the ASRS-6, measures of adolescent social anxiety and depressive symptoms, and parent-adolescent conflict. Adolescent self-reported and parent-reported ASRS-6 positively related with scores from established measures of social anxiety, depressive symptoms, and parent-adolescent conflict. Further, adolescent self-reported (but not parent-reported) ASRS-6 scores significantly discriminated adolescents on referral status. Adolescent self-reported (but not parent-reported) ASRS-6 scores incrementally predicted social anxiety over-and-above depressive symptoms, which commonly co-occur with social anxiety. Conversely, parent-reported (but not adolescent self-reported) ASRS-6 scores incrementally predicted parent-adolescent conflict over-and-above depressive symptoms, which commonly co-occur with conflict. When assessing adolescent ADHD symptoms, adolescents’ and parents’ reports meaningfully vary in their links to validity indicators. As such, among adolescents assessed for social anxiety, clinical assessments of adolescent ADHD symptoms should include both parent reports and adolescent self-reports.     

Serotonin transporter 5-HTTLPR genotype is associated with intrusion and avoidance symptoms of DSM-5 posttraumatic stress disorder (PTSD) in Chinese earthquake survivors

Background and Objectives: Prior studies have found that the serotonin transporter gene-linked polymorphic region (5-HTTLPR) interacts with trauma exposure to increase general risk for Posttraumatic Stress Disorder (PTSD). However, there is little knowledge about the effects of the interaction on distinct symptom clusters of PTSD. This study aimed to investigate the relation between the interaction of 5-HTTLPR and earthquake-related exposures and a contemporary phenotypic model of DSM-5 PTSD symptoms in a traumatised adult sample from China.

Design: A cross-sectional design with gene-environment interaction (G?×?E) approach was adopted. Methods: Participants were 1131 survivors who experienced 2008 Wenchuan earthquake. PTSD symptoms were assessed with the PTSD Checklist for DSM-5 (PCL-5). The 5-HTTLPR polymorphism was genotyped with capillary electrophoresis (CE) in ABI 3730xl genetic Analyzer.

Results: Although there was no significant interaction between 5-HTTLPR and traumatic exposure on total PTSD symptoms, respondents with the LL genotype of 5-HTTLPR who were highly exposed to the earthquake experienced lower intrusion and avoidance symptoms than those with the S-allele carriers.

Conclusions: The findings suggest that the 5-HTTLPR may have an important impact on the development of PTSD and add to the extant knowledge on understanding and treating of posttraumatic psychopathology.     

Hybrid value foraging: How the value of targets shapes human foraging behavior

In hybrid foraging, observers search visual displays for multiple instances of multiple target types. In previous hybrid foraging experiments, although there were multiple types of target, all instances of all targets had the same value. Under such conditions, behavior was well described by the marginal value theorem (MVT). Foragers left the current “patch” for the next patch when the instantaneous rate of collection dropped below their average rate of collection. An observer’s specific target selections were shaped by previous target selections. Observers were biased toward picking another instance of the same target. In the present work, observers forage for instances of four target types whose value and prevalence can vary. If value is kept constant and prevalence manipulated, participants consistently show a preference for the most common targets. Patch-leaving behavior follows MVT. When value is manipulated, observers favor more valuable targets, though individual foraging strategies become more diverse, with some observers favoring the most valuable target types very strongly, sometimes moving to the next patch without collecting any of the less valuable targets.

     

Changes in Problematic Anger,Shame, and Disgust in Anxious and Depressed Adults Undergoing Treatment for Emotion Dysregulation

Emotion dysregulation, the pervasive difficulty managing negative emotions, is a core problem across mood and anxiety disorders. Anger, shame, and disgust are particularly problematic emotions, impacting both disorder severity and treatment outcome. We previously found that a 16-week dialectical behavior therapy skills training group (DBT-ST) was superior to an activities-based support group (ASG) in decreasing emotion dysregulation in 44 adults with high emotion dysregulation who met diagnostic criteria for an anxiety or depressive disorder. We presently examine these participants’ changes in anger, shame, disgust, and distress using self-reports collected over 6 months during and after treatment. Hierarchical linear modeling analyses show that DBT-ST was superior to ASG in decreasing anger suppression (d = 0.93) and distress (d = 1.04). Both conditions significantly reduced shame, disgust propensity, and disgust sensitivity, but neither was superior for these outcomes. The treatments did not significantly reduce anger expression. Mediation analyses suggest that condition indirectly influenced 4-month anger suppression, shame, and distress through its effect on 2-month emotion dysregulation. These findings suggest that DBT-ST is efficacious for certain problematic emotions and distress in depressed and anxious adults and that common factors may account for some, but not all, of its benefits.     

Sex differences in jealousy: the (lack of) influence of researcher theoretical perspective

The sex difference in jealousy is an effect that has generated significant controversy in the academic literature (resulting in two meta-analyses that reached different conclusions on the presence or absence of the effect). In this study, we had a team of researchers from different theoretical perspectives use identical protocols to test whether the sex difference in jealousy would occur across many different samples (while testing whether mate value would moderate the effect). In our samples, we found the sex difference in jealousy to occur using both forced choice and continuous measures, this effect appeared in several different settings, and, we found that mate value moderated participant responses. The results are discussed in light of the controversy surrounding the presence of the effect.     

Persistence and relapse of reinforced behavioral variability

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component of a multiple schedule. In the other component, food was delivered at the same rate, but without the lag variability requirement (i.e., yoked). Following extinction, levels of behavioral variability returned to baseline for both components after response‐independent food delivery (i.e., reinstatement). In Experiment 3, one group of pigeons responded on a lag variability schedule, and the other group responded on a lag repetition schedule. For both groups, levels of behavioral variability increased when alternative reinforcement was suspended (i.e., resurgence). In each experiment, we observed some evidence for extinction‐induced response variability and for variability as an operant dimension of behavior.     

Peer Victimization and Suicidal Thoughts and Behaviors in Depressed Adolescents

Suicide is a leading cause of death among youth worldwide, and depressed adolescents are at a significantly elevated risk to report suicidal ideation, planning, and attempts. Peer victimization is a robust predictor of adolescent suicidal thoughts and behaviors (STBs), but little research has focused on why bullying leads to suicidal thoughts and behaviors. To address this empirical gap, we recruited 340 (246 female) depressed adolescents ages 13–19 (M = 15.59, SD = 1.41) within 48 h of admission for acute psychiatric treatment. At the initial assessment, participants were administered clinical interviews characterizing psychopathology, nonsuicidal self-injury, and STBs (ideation, plans, and attempts). Further, they completed questionnaires assessing 3 forms of victimization (overt, relational, and reputational), recent risky behavior engagement, and psychiatric symptom severity. Controlling for internalizing symptoms and age, overt and reputational bullying were associated with more frequent past month suicide attempts, but not suicide ideation. Past month risky behavior engagement, but not NSSI, mediated the relation between victimization and attempts. However, sex differences revealed that this effect only held for males whereas bullying was directly associated with suicide attempts among females. In contrast, overt and relational bullying were non-linearly associated with suicide plans, and these relations were not mediated by risky behaviors or NSSI. Results highlight the complex network of factors that lead victimized adolescents to engage in STBs and may inform targeted suicide prevention and intervention programs.     

Workplace discrimination: A meta‐analytic extension,critique, and future research agenda

Despite a large and growing literature on workplace discrimination, there has been a myopic focus on the direct relationships between discrimination and a common set of outcomes. The aim of this meta‐analytic review was both to challenge and advance current understanding of workplace discrimination and its associations with outcomes by identifying the pathways through which discrimination affects outcomes, examining boundary conditions to explain when discrimination is most harmful for employees, and exploring a potential third variable explanation for discrimination–outcome relationships. Mediation tests indicated that workplace discrimination is associated with employee outcomes through both job stress and justice. Moderator analyses showed that discrimination appears to be most detrimental when it is observed rather than personally experienced, interpersonal rather than formal, and measured broadly rather than specifically. We also found that discrimination–outcome relationships differ across work and nonwork contexts and as a function of the social identity targeted by discrimination. Discrimination generally explained meaningful incremental variance in outcomes after controlling for the effects of negative affectivity, but the relationships between discrimination and health were substantially decreased. We conclude by offering a constructive critique of the empirical discrimination literature and by detailing an agenda for future research.

Collectivizing Rescue Obligations in Bioethics

Bioethicists invoke a duty to rescue in a wide range of cases. Indeed, arguably, there exists an entire medical paradigm whereby vast numbers of medical encounters are treated as rescue cases. The intuitive power of the rescue paradigm is considerable, but much of this power stems from the problematic way that rescue cases are conceptualized—namely, as random, unanticipated, unavoidable, interpersonal events for which context is irrelevant and beneficence is the paramount value. In this article, I critique the basic assumptions of the rescue paradigm, reframe the ethical landscape in which rescue obligations are understood, and defend the necessity and value of a wider social and institutional view. Along the way, I move back and forth between ethical theory and a concrete case where the duty to rescue has been problematically applied: the purported duty to regularly return incidental findings and individual research results in genomic and genetic research.
