Altered emotion dynamics may represent a transdiagnostic risk factor for mood psychopathology. The present study examined whether altered emotion dynamics were associated with bipolar and depressive psychopathology concurrently and at a three-year follow-up. ⋯ The present study provided a unique demonstration that altered emotion dynamics differentially predicted bipolar and depressive psychopathology concurrently and prospectively. Emotion dynamics are important to both digital phenotyping and mobile-based interventions as emotional instability offers a measurable risk factor that is identifiable prior to illness onset.

Military sexual trauma (MST), and assault as opposed to harassment-only MST in particular, is associated with lower sexual function among female service members/veterans (SM/Vs). Recent research revealed that higher posttraumatic stress disorder (PTSD) symptom clusters of anhedonia and dysphoric arousal mediated the association of assault MST and sexual function. Such clusters represent the depressive symptoms of PTSD, and theories of sexual function suggest that depression worsens sexual function. The impact of depression on the association of MST and sexual function has yet to be tested. ⋯ Even after accounting for established covariates and mediators of assault MST and sexual function, depression accounted for a significant amount of variance in this association. Treatment of poor sexual function must address depressive symptoms. As medications for depression can exacerbate sexual issues, psychotherapy may be the most effective treatment strategy.

White matter abnormalities have been implicated in mental disorders including major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SZ); however, the shared and distinct white matter integrity across mental disorders is still unclear. ⋯ Our findings suggest that abnormally reduced white matter integrity in the interhemispheric and thalamocortical circuit could be consistently involved in the pathogenesis of MDD, BD and SZ.

Emotional support is highly protective against poor mental health. Though several measures of emotional support exist, none specifically addresses social media (SM) as a source of emotional support. Therefore, the objectives of this study were to determine if SM-based emotional support is an extension of or distinct construct from face-to-face (FTF) emotional support and to assess the independent associations between each domain of emotional support and depression risk among U.S. young adults. ⋯ While FTF emotional support was associated with slightly lower odds of depression, SM-based emotional support was associated with slightly greater odds of depression. It may be valuable for clinicians treating individuals with depression to ask about sources of emotional support.

The interpersonal theory of suicide posits that perceived burdensomeness, thwarted belongingness, and acquired capability together interact to increase risk for lethal self-injury. Despite the prominence of this theoretical model, few studies have directly tested the three-way interaction central to the theory, with mixed findings reported in studies to date. The objective of this study was to test the theorized three-way interaction in relation to suicidal behaviors in a large sample of college students. ⋯ This study adds to a small but growing body of research testing the three-way interaction among perceived burdensomeness, thwarted belongingness, and capability for suicide in relation to suicidal behaviors. Longitudinal studies using measures that distinguish between suicidal ideation and suicide attempt within the ideation-to-action framework are needed.
