Adolescent girls' interpersonal vulnerability to depressive symptoms: a longitudinal examination of reassurance-seeking and peer relationships

A transactional, interpersonal framework involving adolescents' reassurance-seeking and peer experiences may be useful for understanding the emergence of gender differences in depression prevalence during the adolescent transition. Sociometric nominations of peer acceptance/rejection and ratings of friendship quality provided by adolescents and their friends were used to measure peer experiences among 6th-8th-grade adolescents (N=520) over 3 annual time points. After controlling for age and pubertal development, significant but small prospective effects offered mixed support for hypotheses: (a) depressive symptoms and negative peer relations predicted increasing levels of girls' reassurance-seeking; (b) initial levels of reassurance-seeking and depressive symptoms predicted deteriorating friendship quality among girls and low friendship stability, respectively; and (c) reassurance-seeking combined with poor peer experiences predicted increases in girls' depressive symptoms.     

Family Systems and Ecological Perspectives on the Impact of Deployment on Military Families

The scope of sustained military operations in Iraq and Afghanistan has placed great demands on the Armed Forces of the United States, and accordingly, military families have been faced with deployments in more rapid succession than ever before. When military parents fulfill occupational duties during wartime, military children and families face multiple challenges, including extended separations, disruptions in family routines, and potentially compromised parenting related to traumatic exposure and subsequent mental health problems. Such challenges can begin to exert a significant toll on the well-being of both individuals and relationships (e.g., marital, parent–child) within military families. In order to respond more effectively to the needs of military families, it is essential that mental health clinicians and researchers have a better understanding of the challenges faced by military families throughout the entire deployment experience and the ways in which these challenges may have a cumulative impact over multiple deployments. Moreover, the mental health field must become better prepared to support service members and families across a rapidly evolving landscape of military operations around the world, including those who are making the transition from active duty to Veteran status and navigating a return to civilian life and those families in which parents will continue to actively serve and deploy in combat zones. In this article, we utilize family systems and ecological perspectives to advance our understanding of how military families negotiate repeated deployment experiences and how such experiences impact the well-being and adjustment of families at the individual, dyadic, and whole family level.     

Relational Security Moderates the Effect of Serotonin Transporter Gene Polymorphism (5-HTTLPR) on Stress Generation and Depression among Adolescents

Previous research demonstrates that carriers of the short allele of the serotonin transporter gene (5-HTTLPR) show both greater susceptibility to depression in response to stressful life events and higher rates of generation of stressful events in response to depression. The current study examines relational security (i.e., self-reported beliefs about attachment security) as a moderator of these effects, building on emerging research suggesting that the short allele acts as a marker of sensitivity to the social environment. Participants were 354 Caucasian adolescents oversampled for maternal depression (137 male, 217 female), assessed at ages 15 and 20. Results indicated that the short allele predicted increased stress generation at age 20 among those with low age 15 security but decreased stress generation among those with high security, and revealed a three-way interaction between age 15 depression, age 15 security, and genotype, where depression predicted stress generation only among short allele carriers with low security. Further, among boys only, security interacted with genotype to predict longitudinal changes in depression diagnosis, with the s-allele predicting relative increases in probability of depression among boys with low security but decreases among boys with high security. Results support the notion of the short allele as a marker of social reactivity, and suggest that attachment security may buffer against the genetic vulnerability introduced by the short allele, in line with predictions of the differential susceptibility theory.     

Noninvasive Prenatal Testing/Noninvasive Prenatal Diagnosis: the Position of the National Society of Genetic Counselors

The 1997 discovery of free fetal DNA in maternal plasma launched clinical researchers’ efforts to establish a reliable method for non-invasive prenatal testing for fetal genetic conditions. Various methods, including, but not limited to, massively parallel sequencing (MPS) and selective analysis of cell-free fetal DNA in maternal plasma, have recently been developed as highly sensitive and specific noninvasive screening tools for common fetal chromosome aneuploidies. Incorporating these new noninvasive technologies into clinical practice will impact the current prenatal screening paradigm for fetal aneuploidy, in which genetic counseling plays an integral role. The National Society of Genetic Counselors (NSGC) currently supports Noninvasive Prenatal Testing/Noninvasive Prenatal Diagnosis (NIPT/NIPD) as an option for patients whose pregnancies are considered to be at an increased risk for certain chromosome abnormalities. NSGC urges that NIPT/NIPD only be offered in the context of informed consent, education, and counseling by a qualified provider, such as a certified genetic counselor. Patients whose NIPT/NIPD results are abnormal, or who have other factors suggestive of a chromosome abnormality, should receive genetic counseling and be given the option of standard confirmatory diagnostic testing.     

Perceived physical and social causality in animated motions: spontaneous reports and ratings

Michotte argued that we perceive cause-and-effect, without contributions from reasoning or learning, even in displays of two-dimensional moving shapes. Two studies extend this line of work from perception of mechanical to social causality. We compared verbal reports with structured ratings of causality to gain a better understanding of the extent to which perceptual causality occurs spontaneously or depends on instruction or context. A total of 120 adult observers (72 in the main experiment, 48 in an initial experiment) saw 12 (or 8) different computer animations of shape A moving up to B, which in turn moved away. Animations factorially varied the temporal and spatial relations of the shapes, and whether they moved rigidly or in a non-rigid, animal-like manner. Impressions of social as well as physical causality appeared in both free reports and ratings. Perception of physical causality was stronger than perception of social causality, particularly in free reports. No differences of this nature appear in infants and children, so the asymmetry may reflect learnt knowledge. Physical causality was relatively unspecific initially, but discrimination of causal and delayed control events improved with exposure to multiple events. Experience seems to affect the causal illusion even over a short timeframe; the idea of 'one-trial causality' may be somewhat misleading. Regardless of such effects on the absolute level of responses, the different measures showed similar patterns of variation with the spatio-temporal configuration and type of motion. The good fit of ratings and reports validates much recent work in this area.     

Face distinctiveness and delayed testing: differential effects on performance and confidence

The author investigated the effect of delayed testing on participants' memory for distinctive and typical faces. Participants viewed distinctive and typical faces and were then tested for recognition immediately or after a delay of 3, 6, or 12 weeks. Consistent with prior research, analysis of measure of sensitivity (d') showed that participants performed better on distinctive rather than typical faces, and memory performance declined with longer retention intervals between study and testing. Furthermore, the superior performance on distinctive faces had vanished by the 12-week test. Contrary to d' data, however, an analysis of confidence scores indicated that participants were still significantly more confident on trials depicting distinctive faces, even with a 12-week delay between study and recognition testing.     

Predictors of Attributional Style Change in Children

A number of studies have supported the hypothesis that negative attributional styles may confer vulnerability to the development of depression. The goal of this study was to explore factors that may contribute to the development of negative attributional styles in children. As hypothesized, elevated levels of depressive symptoms and hopelessness at the initial assessment predicted negative changes in children's attributional styles over the 6-month follow-up period. In addition, elevated levels of verbal victimization occurring between the 2 assessments, as well as that occurring in the 6 months preceding the initial assessment, prospectively predicted negative changes in children's attributional styles over the follow-up. Further, initial depressive symptoms and verbal victimization during the follow-up continued to significantly predict attributional style change even when the overlap among the predictors was statistically controlled. Contrary to the hypotheses, however, neither parent-reported levels of overall negative life events nor parents' attributions for their children's events predicted changes in children's attributional styles.     

The belief in a just world and immanent justice reasoning in adults

Deciding that negative experiences are punishment for prior misdeeds, even when plausible causal links are missing, is immanent justice (IJ) reasoning (Piaget, 1932/1965). Three studies examined a just world theory analysis of IJ reasoning in adults (Lerner, 1980). Studies 1 and 2 varied the valence of a target person's behavior prior to them experiencing an unrelated negative (car accident, Study 1) or positive (lottery win, Study 2) outcome. Participants viewed the outcomes as the result of prior behavior most when they fit deservingness expectations (good person won the lottery, bad person injured in automobile accident), suggesting that just world concerns influenced IJ reasoning. The lottery-winning finding (Study 2) also extends IJ reasoning to positive experiences. A third study found that a manipulation of just world threat in one context (prolonged or ended suffering of an HIV victim) influenced IJ responses in a subsequent unrelated context (automobile accident scenario).
