I feel good? Anhedonia might not mean "without pleasure" for people treated for opioid use disorder.
Anhedonia is usually defined as partial or total loss of the capacity for pleasure. People with anhedonia in the context of major depressive disorder may have an unexpected capacity for event-related mood brightening, observable when mood is assessed dynamically (with smartphone-based ecological momentary assessment [EMA]) rather than only statically via questionnaire. We used EMA to monitor mood and pleasant events for 4 weeks in 54 people being treated with opioid agonist medication for opioid-use disorder (OUD), which is also associated with anhedonia, said to manifest especially as loss of pleasure from nondrug reward. ⋯ As hypothesized, instances of nondrug pleasure were as frequent in OUD patients as in controls-and were not rated much less pleasurable (d = .18, 95% CI [-.03, .35]). Event-related mood brightening occurred in both abstinent and nonabstinent OUD patients (ds = .18 to .37, CIs [-.01, .57]) and controls (ds = .04 to .60, CIs [-.17, .79]), brightening before each event began earlier for controls than OUD patients, but faded similarly postevent across groups. Our findings add to the evidence that anhedonia does not rule out reactive mood brightening, which, for people with OUD being treated on opioid agonist medication, can be elicited by nondrug activities.

Extensive research has examined attention bias to threat in the context of anxiety in adults, but little is understood about this association in young children, and there is a dearth of longitudinal research examining whether attention bias to threat predicts anxiety over time in childhood. In the current study, a sample of 180 children participated in a longitudinal study, first as preschoolers and again as they transitioned to formal schooling. At baseline, children aged 3-4 years completed a free-viewing eye-tracking task with angry-neutral and happy-neutral face pairs and an assessment of behavioral inhibition (BI). ⋯ However, BI interacted with dwell bias for angry faces to predict trajectories of anxiety over the transition to school. An unexpected interaction between BI and dwell bias for happy faces was also found, with dwell for happy faces associated with lower anxiety for children higher in BI. The findings are consistent with recent developmental models of the BI-anxiety relationship and indicate that attention bias modification may not be suitable for young children, for whom attention bias to threat may be normative.

Reports an error in "Dimensions of deprivation and threat, psychopathology, and potential mediators: A multi-year longitudinal analysis" by Adam Bryant Miller, Margaret A. Sheridan, Jamie L. Hanson, Katie A. ⋯ Consistent with predictions, deprivation was associated with risk for externalizing problems via effects on verbal abilities at age 14. Threat was associated longitudinally with both internalizing and externalizing problems, but these effects were not mediated by verbal abilities. Results suggest that unique developmental mechanisms link different forms of adversity with psychopathology. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Prior research demonstrates a link between exposure to childhood adversity and psychopathology later in development. However, work on mechanisms linking adversity to psychopathology fails to account for specificity in these pathways across different types of adversity. Here, we test a conceptual model that distinguishes deprivation and threat as distinct forms of childhood adversity with different pathways to psychopathology. ⋯ Consistent with predictions, deprivation was associated with risk for externalizing problems via effects on verbal abilities at age 14. Threat was associated longitudinally with both internalizing and externalizing problems, but these effects were not mediated by verbal abilities. Results suggest that unique developmental mechanisms link different forms of adversity with psychopathology. (PsycINFO Database Record

Sex differences in the etiology of youth antisocial behavior are an intuitively appealing hypothesis given the consistently higher prevalence of antisocial behavior in boys versus girls. Although a few early studies supported this possibility, reporting stronger genetic influences in females and stronger environmental influences in males, subsequent meta-analyses found that antisocial behavior was equally heritable in males and females. Critically however, none of the meta-analyses evaluated whether sex differences in etiology might be enhanced in particular subpopulations or contexts. ⋯ Critically, these findings were confirmed when we reanalyzed meta-analytic data from Burt (2009a) separately by informant. Such findings suggest that, at least in school contexts, the etiology of antisocial behavior does indeed vary across sex. Implications are discussed. (PsycINFO Database Record
