This paper puts forward an explanation for the frequent co-occurrence of attachment and behavior problems in children and the implications of this for interventions; presents preliminary evidence that some behaviorally based parenting programs reduce child behavior problems through two separate, but mutually reinforcing, processes-improved attachment relationships and increased parental use of behavior management techniques; and suggests next steps for the field to improve outcomes for those children who, without interventions that addresses both relationship building and behavior management, are at risk of significant long-term difficulties.

Sexual minority (SM) individuals appear to be at greater risk for obsessive-compulsive disorder (OCD). Despite this, little is known about OCD presentation and treatment outcomes among SM individuals. Although some research has suggested that SM individuals may be more likely to endorse intrusive thoughts related to violence/sex/religion compared to heterosexual individuals, extant literature has neglected to examine potential differences across different SM groups, a notable limitation given the apparent differences in the types of minority stress that each group experiences and the unique health disparities affecting each group.

Although obsessive-compulsive disorder (OCD) is associated with clinically significant distress, many OCD patients do not seek treatment. Studies show that Black Americans with OCD are even less likely to obtain treatment due to differences in access. This study explored demographic and symptom outcomes associated with mental health service use for obsessions and compulsions among a nationally representative sample of African American adults (n = 3,570).

The leaf economics spectrum (LES) characterizes a tradeoff between building a leaf for durability versus for energy capture and gas exchange, with allocation to leaf dry mass per projected surface area (LMA) being a key trait underlying this tradeoff. However, regardless of the biomass supporting the leaf, high rates of gas exchange are typically accomplished by small, densely packed stomata on the leaf surface, which is enabled by smaller genome sizes. Here, we investigate how variation in genome size-cell size allometry interacts with variation in biomass allocation (i.

Background: Improving adherence to pre-exposure prophylaxis (PrEP) via digital health interventions (DHIs) for young sexual and gender minority men who have sex with men (YSGMMSM) is promising for reducing the HIV burden. Measuring and achieving effective engagement (sufficient to solicit PrEP adherence) in YSGMMSM is challenging.

Objective: This study is a secondary analysis of the primary efficacy randomized controlled trial (RCT) of Prepared, Protected, Empowered (P3), a digital PrEP adherence intervention that used causal mediation to quantify whether and to what extent intrapersonal behavioral, mental health, and sociodemographic measures were related to effective engagement for PrEP adherence in YSGMMSM.
