Intrapersonal and Interpersonal Factors Influencing Adolescents' Decisions About Having Sex: A Test of Sufficiency of the Theory of Planned Behavior1

This study tested the theory of planned behavior's (TPB) expectation that attitudes, social norms, and self‐efficacy would mediate other variables' effects on intention for having sex and probability of having sex. Longitudinal data were collected from 790 high‐school‐aged adolescents. In an intrapersonal variable model, sensation seeking, alcohol use, hard work, smoking, and moral beliefs had mediated effects, but the last 2 also had direct effects (on intention and behavior, respectively). In an interpersonal model, school attachment had mediated effects, pressure to have sex had a direct effect on behavior, and parent communication and number of sexually active friends had both. Intrapersonal variable effects were better described by the TPB than those of interpersonal variables. Targeting distal psychosocial factors may enhance intervention efficacy.     

A Review of Functional Analysis Methods Conducted in Public School Classroom Settings

The use of functional behavior assessments (FBAs) to address problem behavior in classroom settings has increased as a result of education legislation and long-standing evidence supporting function-based interventions. Although functional analysis remains the standard for identifying behavior–environment functional relations, this component is rarely included in FBAs in practice. To address this research-to-practice gap, we searched the FBA literature to identify studies including functional analyses (FAs) conducted in students’ usual classrooms and implemented by school personnel in public school settings. FAs were defined broadly as assessments involving systematic manipulation of one or more antecedent or consequent variable to evaluate environmental influences on student problem behavior. We identified 39 studies including FAs for 88 participants. All studies were coded with regard to FA approaches and procedures as well as student, classroom, and implementer characteristics. In addition, we evaluated the extent to which FA methods in the study sample aligned with previous recommendations to address practical barriers to implementation. Results revealed a range of FA approaches that varied according to student and classroom characteristics, as well as several strategies to address implementation barriers that have been under-utilized in classroom-based FAs to date.     

The Mediating Roles of Adolescent Disclosure and Parental Knowledge in the Association Between Parental Warmth and Delinquency Among Korean Adolescents

The purpose of this study was to examine the association between parental warmth and adolescent delinquency, the potential mediating roles of adolescent disclosure and parental knowledge, and gender differences in such association among Korean adolescents. We hypothesized that (1) parental warmth would be significantly and negatively associated with delinquency, (2) adolescent disclosure and parental knowledge would mediate the association between parental warmth and adolescent delinquency, and (3) the association between parental warmth and adolescent delinquency mediated through adolescent disclosure and parental knowledge would be stronger for adolescent girls than boys. Using a sample of 3125 Korean adolescents from nationally representative and longitudinal data (Korea Youth Panel Survey), results from path analyses demonstrated that findings were consistent with US samples, suggesting a negative association between parental warmth and adolescent delinquency. Further, when Korean adolescents perceived parents to be warmer, they were more likely to disclose personal information to their parents. In turn, higher levels of disclosure were associated with higher levels of parental knowledge about their adolescent children’s activities. Finally, tests of gender differences suggested that parental warmth was more closely associated with adolescent disclosure among girls than boys. Results supported a process model through which parents may shape adolescent children’s delinquency.     

Mindful awareness of feelings increases neural performance monitoring

Mindfulness has been associated with enhanced performance monitoring; however, little is known about the processes driving this apparent neurocognitive benefit. Here, we tested whether focusing present-moment awareness toward the nonjudgmental experience of emotion facilitates rapid neural responses to negative performance outcomes (i.e., mistakes). In particular, we compared whether directing present-moment awareness toward emotions or thoughts would enhance the neurophysiological correlates of performance monitoring: the error-related negativity (ERN) and the error positivity (Pe). Participants were randomly assigned to either a thought-focused or an emotion-focused group, and first they completed a preinduction go/no-go task. Subsequently, the groups followed inductions that promoted mindful attention toward either thoughts or emotions, before completing a final postinduction go/no-go session. The results indicated that emotion-focused participants demonstrated higher neural sensitivity to errors in the time course of the ERN, whereas focusing on thoughts had no effect on performance monitoring. In contrast, neither induction procedure altered the amplitude of the later Pe component. Although our manipulations also induced changes in behavior, the ERN effects remained significant after controlling for performance. Thus, our results suggest that mindfulness meditation boosts early neural performance monitoring (ERN amplitude), specifically through meditation’s influence on affective processing.     

Predicting Treatment Outcomes From Internet-Based Cognitive Behavior Therapy for Obsessive–Compulsive Disorder

Internet-based cognitive-behavioral therapy (ICBT) with therapist support shows promise as a treatment for obsessive-compulsive disorder (OCD). Yet, not all patients respond to ICBT. It is therefore important to identify predictors of ICBT outcomes to determine who is likely to benefit. Relative to the large literature on predictors of outcomes for in-person CBT for OCD, very few studies have investigated ICBT predictors. Therefore, we analyzed predictors of outcome in an open trial (n = 30) of ICBT for OCD using the OCD-NET platform, which consists of 10 online modules delivered with therapist support. The Yale-Brown Obsessive-Compulsive Scale (YBOCS) was administered by independent raters as the primary outcome measure at baseline and posttreatment. In this sample, greater baseline OCD severity and OCD-related avoidance behaviors were associated with higher end-state OCD symptoms (i.e., poorer outcome). Patients with a past history of face-to-face CBT for OCD also had worse outcomes. Although these results require replication, these factors may identify individuals at risk for poor ICBT outcomes.     

Intelligence: new findings and theoretical developments

We review new findings and new theoretical developments in the field of intelligence. New findings include the following: (a) Heritability of IQ varies significantly by social class. (b) Almost no genetic polymorphisms have been discovered that are consistently associated with variation in IQ in the normal range. (c) Much has been learned about the biological underpinnings of intelligence. (d) "Crystallized" and "fluid" IQ are quite different aspects of intelligence at both the behavioral and biological levels. (e) The importance of the environment for IQ is established by the 12-point to 18-point increase in IQ when children are adopted from working-class to middle-class homes. (f) Even when improvements in IQ produced by the most effective early childhood interventions fail to persist, there can be very marked effects on academic achievement and life outcomes. (g) In most developed countries studied, gains on IQ tests have continued, and they are beginning in the developing world. (h) Sex differences in aspects of intelligence are due partly to identifiable biological factors and partly to socialization factors. (i) The IQ gap between Blacks and Whites has been reduced by 0.33 SD in recent years. We report theorizing concerning (a) the relationship between working memory and intelligence, (b) the apparent contradiction between strong heritability effects on IQ and strong secular effects on IQ, (c) whether a general intelligence factor could arise from initially largely independent cognitive skills, (d) the relation between self-regulation and cognitive skills, and (e) the effects of stress on intelligence.     

Individual development and evolution: experiential canalization of self-regulation

In this article, we contrast evolutionary and psychobiological models of individual development to address the idea that individual development occurring in prototypically risky and unsupportive environments can be understood as adaptation. We question traditional evolutionary explanations of individual development, calling on the principle of probabilistic epigenesis to suggest that individual development resulting from the combined activity of genes and environments is best understood to precede rather than follow from evolutionary change. Specifically, we focus on the ways in which experience shapes the development of stress response physiology, with implications for individual development and intergenerational transmission of reactive, as opposed to reflective, phenotypes. In doing so, we describe results from several analyses conducted with a longitudinal data set of 1,292 children and their primary caregivers followed from birth. Our results indicate that the effects of poverty on stress response physiology and on the development of the self-regulation of behavior represent instances of the experiential canalization of development with implications for understanding the genesis and "adaptiveness" of risk behavior.
