Description
The main objective of this study was to use a genetically-informative design to examine the putative influences of maternal perceived prenatal stress, obstetrical complications, and gestational age on infant dysregulation, competence, and developmental maturity. Specifically, whether or not prenatal and obstetrical environmental conditions modified the heritability of infant outcomes was examined. A total of 291 mothers were interviewed when their twin infants were 12 months of age. Pregnancy and twin birth medical records were obtained to code obstetrical data. Utilizing behavioral genetic models, results indicated maternal perceived prenatal stress moderated genetic and environmental influences on developmental maturity whereas obstetrical complications moderated shared environmental influences on infant competence and nonshared environmental influences on developmental maturity. Gestational age moderated the heritability and nonshared environment of infant dysregulation, shared and nonshared environmental influences on competence, and nonshared environmental influences on developmental maturity. Taken together, prenatal and obstetric conditions were important nonlinear influences on infant outcomes. An evolutionary perspective may provide a framework for these findings, such that the prenatal environment programs the fetus to be adaptive to current environmental contexts. Specifically, prenatal stress governs gene expression through epigenetic processes. Findings highlight the utility of a genetically informative design for elucidating the role of prenatal and obstetric conditions in the etiology of infant developmental outcomes.

Description
Cognitive reappraisal, or redefining the meaning of a stressful circumstance, is useful in regulating emotional responses to acute stressors and may be mobilized to up- or down- regulate the stressors’ emotional salience. A conceptually-related but more targeted emotion regulation strategy to that offered by cognitive reappraisal, termed positive cognitive shift, was examined in the current study. Positive cognitive shift (“PCS”) is defined as a point of cognitive transformation during a chronic, stressful situation that alters the meaning and emotional salience of the situation for the individual. Key aspects of the PCS that differentiate it from the broader reappraisal construct are that it 1) is relevant to responses to chronic (versus acute) aversive events, 2) is deployed when there is a mismatch between coping and stressors, and 3) involves insight together with redefinition in meaning of the situation generating stress. The current study used qualitative and quantitative analyses to 1) examine whether PCS is an observable, reliable, and valid experience in response to a stressful event that occurred in the past year, and 2) test whether PCS moderates the relations between the number of past-year stressful life circumstances and subsequent emotional well-being and functional health. A community sample of 175 middle-aged individuals were interviewed regarded a past chronic stressor and completed questionnaires regarding number of past year stressors and health outcomes. Theory-based coding of interviews was conducted to derive reliable scores for PCS, and findings indicated that PCS was evident in 37.7 % of participant responses. Furthermore, PCS scores were related positively to openness, personal growth from one’s most difficult lifetime event, and affect intensity-calm, in line with predictions. Also in line with prediction, PCS moderated the relations between number of past-year life events and health outcomes, such that the deleterious relations between past year stressful events and cognitive functioning, wellbeing, positive affect, and negative affect were weaker among individuals higher versus lower in PCS. Of note, PCS moderation effects diminished as the number of stressful events increased.

Description
The relationship of attachment style to both the selection and efficacy of emotion management strategies in adult dyadic contexts is not well elucidated. In non-romantic contexts, the interplay between emotion management and individual attachment style may provide a better understanding of how affect can be mitigated in daily life. The present study investigated these interactions by studying 56 pairs of college age women who were close friends. Participants were asked to have a conversation about a current source of concern/distress to one partner, while seated in the laboratory. After the conversation, participants were asked to report their subjective experience of several emotions during the conversation, such as ‘sadness,’ ‘joy,’ and ‘fear.’ Participants were also asked to complete a questionnaire assessing adult attachment style, specifically attachment anxiety and avoidance. Behavior during the conversation was coded for co-rumination and co-cognitive reappraisal by the “listener.” Listener attachment insecurity showed a trending association with increased use of co-detached reappraisal, for both avoidance (p=0.14) and anxiety (p=0.14). Listener attachment insecurity also predicted lower use of co-rumination, for both anxiety (p=0.10) and avoidance (p=0.02). Speaker attachment insecurity moderated the relationship between co-detached reappraisal and speaker emotion. Greater co-detached reappraisal predicted higher reports of non-fear negative and positive emotions, but only for high-avoidance speakers. Greater co-detached reappraisal also predicted greater non-fear negative emotions among speakers high, but not low, on attachment anxiety. Greater listener use of co-positive reappraisal was associated with higher reports of speaker fear; this effect was not moderated by speaker attachment style. These findings are discussed in relation to theoretical conceptions of attachment style, and in terms of the impact of context on emotion.

Description
The purpose of our study was to evaluate whether viewing videos of dogs had an effect on the stress response of college students. While there is strong support in the literature for demonstrating the beneficial effect of human-canine interactions on human stress indicators, there is very little to no literature on whether or not this phenomenon translates across a digital medium. We hypothesized that when exposed to a video of golden retriever puppies after a stress-inducing task, an individual would experience an increase in blood pressure recovery rate and a decline in perceived stress. In order to study this, we put together several surveys to test our participants' perceived stress, and we measured blood pressure several times in order to obtain a physiological measure of stress. Additionally, in order to produce a guaranteed stress response in our participants, we gave them 2 minutes to prepare a 4 minute video-recorded speech that they were not made aware of prior to entering the testing facility. After the speech task, the experimental group quietly viewed a pleasant 4 minute video containing imagery of dogs, while the control group sat silently for the same duration of time. During this time, the control group was asked to mentally review their performance and to focus intently on the feelings they experienced while giving their speech. Through these measures we found a significant recovery rate in systolic blood pressure and a trending difference between groups for the decline in negative affect. The data demonstrated that the experimental group had blood pressure levels that were significantly closer to their baseline levels when compared to the control group, whose blood pressure did not decline at the same rate. Additionally, the experimental group experienced a higher level of change in negative affect when asked to self-report their level of stress before the speech task and after the conditional recovery period. Interestingly, these findings can be applied to recent literature suggesting that systolic blood pressure is the most important factor of cardiac health to consider when assessing an individual for risk of heart disease or cardiac arrest. While the sample size of this study was small, the significant reduction in systolic blood pressure within the experimental group could indicate the possible efficacy of utilizing digital media containing imagery of canines as a form of therapy for systolically-hypertensive individuals as a means of managing their condition.

Description
Prior research has identified that clinicians in the treatment of eating disorders often do not adhere closely to empirically-supported treatments (EST), and are particularly likely to modify Cognitive-Behavioral therapy (CBT). Several reasons for this phenomenon, dubbed "clinician drift", have been identified, including level of clinician training, education, and type of patient care. In addition to the phenomenon of clinician drift, there has been a growing controversy within the field of clinical psychology about the compatibility of ESTs and multiculturalism. Some argue that the standardization inherent to EST resists the concept of cultural adaptability; while others have countered that cultural adaptability is essential in order for empirically supported treatments to remain relevant, ethical, and effective. In order to shed more light on this issue, this study examined how clinicians tend to drift from CBT in the treatment of Latinos suffering from eating disorders, in order to accommodate Latino culture and elements of eating behavior specific to Latino populations. We both attempted to replicate prior findings regarding predictors of clinician drift, as well as build upon the little existing research into the "culturally-motivated clinician drift." It was discovered that no therapist characteristics or client characteristics were predictive of drift. However, the majority of the sample still adapted or abandoned at least part of the CBT treatment. Their responses regarding the weaknesses of CBT for their Spanish-speaking clients can provide insight into how the treatment can be modified for more diverse clients.

Description
Longitudinal data from European-American (EA) and Mexican-American (MA) families (n = 179 mothers, fathers, and youth; 41% MA) was used to test a bio-psycho-cultural model of the effect of non-responsive parenting on externalizing problems in young adult offspring through the effect on the stress response system. Parenting behavior (acceptance, rejection, harsh discipline) was assessed when children were in late childhood (12-13 years), cortisol samples were collected during late adolescence (18-19 years), and externalizing problems were measured in young adulthood (21-22 years). Latent profile analyses were used to examine patterns of parenting behavior in EA and MA families. A path analysis framework was used to examine how non-responsive parenting interacted with acceptance to predict adolescent stress response and subsequent externalizing problems in EA and MA young adults. Results showed different patterns of parenting behavior in EA versus MA families, with MA families demonstrating a profile of high acceptance and high non-responsiveness at higher rates than EA families. In MA families, youth adherence to the traditional cultural value of familismo related to more positive perceptions of parenting behavior. Across ethnic groups, parent rejection only predicted higher externalizing problems in young adults when acceptance was high. The effect of parent harsh discipline on offspring stress response differed by ethnicity. In MA families, harsh discipline predicted dysregulated stress response in youth when acceptance was low. In EA families, harsh discipline did not relate to youth stress response. Overall, results increase the understanding of normative and adaptive parenting behaviors in MA families. Findings inform the development of culturally-competent parenting-focused interventions that can better prevent dysregulated stress response and externalizing behavior problems in ethnically diverse youth.

Description
Research suggests that early family relationships have critical influences on later physical and psychological health, but most studies have focused on the influence of mothers ignoring the unique impacts of fathers. One mechanism by which families may transmit risk is by repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis in the short-term that leads to adult neurobiological dysregulaton, evident in hyper- or hypo-cortisol levels. Using 218 father-child dyads from the Parent and Youth Study (PAYS), the current study investigated whether father involvement in adolescence predicted youth cortisol AUCg and reactivity to a stress task in young adulthood, and whether this relation was mediated by youth perceptions of mattering to their fathers in adolescence. Results revealed that higher father-reported father involvement predicted lower cortisol AUCg in youth when mattering was included in the model, although father involvement was not a statistically significant predictor of AUCg or cortisol reactivity when mattering was not included. Additionally, children who reported higher father involvement also reported higher feelings of mattering, but this association was only statistically significant for girls and European American youth. Youth feelings of mattering did not predict their cortisol reactivity or AUCg in young adulthood. Results suggest that future research should include fathers when investigating the effects of family relationships on youth psychophysiological development.

Description
The theory of biological sensitivity to context (BSC; Boyce & Ellis, 2005) posits that specific biological characteristics, such as vagal tone, may confer risk for physical and mental health outcomes for some children but promote health for others. High levels of resting respiratory sinus arrhythmia (RSA), an index of vagal tone, may confer susceptibility to the effects of the caregiving environment on child development. Consistent with BSC, I expected that, relative to infants with lower RSA, infants with higher RSA would demonstrate fewer behavior problems if their mothers reported fewer postpartum depressive symptoms, but more behavior problems if their mothers reported more postpartum depressive symptoms. I also evaluated whether observed child social engagement with their mothers mediated children's biological sensitivity to the effects of postpartum depressive symptoms on behavior problems in early childhood. I evaluated a mediated moderation model among a sample of 322 low-income Mexican American mother-infant dyads. As expected, the RSA x maternal depressive symptoms interaction, controlling for covariates, was a significant predictor of internalizing, externalizing and total behavior problems, and high vagal tone conferred susceptibility for externalizing behavior problems. Contrary to my hypothesis, children with low RSA may be more susceptible to the effects of maternal postpartum depressive symptoms on children's internalizing and total behavior problems, and child social engagement did not account for these effects. Among infants in economically disadvantaged families, lower RSA and fewer maternal depressive symptoms may promote resilience, and more research is needed to understand behavioral mediators of biological sensitivity.

Description
The current study examined effects of representations of relationships with parents on young adults’ representations of romantic relationships and self-esteem, with particular attention paid to the role of fathers, instability of representations, and bidirectional effects. Data were obtained from two waves (Waves 4 and 5) of a five-wave study. At wave 4, 287 young adults (mean age = 20) participated, and at Wave 5, 276 young adults (mean age = 22) participated. One-time interviews (Behavioral Systems Questionnaires; BSQ) were conducted to measure the level of representations of relationships with parents. Nightly diary checklists (7 nights at Wave 4, and 5 nights at Wave 5) were used to measure the level and instability of representations of romantic relationships (BSQ) and self-esteem (Rosenberg Self Esteem Scale). Two styles of representations, including secure versus dismissing (e.g., relying on parents or romantic partners when distressed versus not relying on them) and preoccupied (e.g., worrying about rejection and excessive dependency) were measured for relationships with parents and romantic partners. The results showed evidence for unique roles of fathers, instability of representations, and bidirectional effects. Relationships with fathers affected young adults’ self-esteem. More nightly fluctuations in security with romantic partners predicted higher levels of security with romantic partners, but only in the context of more secure relationships. More nightly fluctuations in self-esteem predicted more dismissive representations of fathers. Bidirectional effects involved young adults’ representations of both romantic relationships and self-esteem, and their representations of relationships with parents. The relation between instability of representations of romantic relationships and later security in romantic relationships might represent learning about romantic relationships. The relation between instability of self-esteem and later dismissive styles with fathers (e.g., not relying on fathers when distressed) at this age might be an indication of learning to become autonomous from fathers. Finally, I also hypothesize that during emerging adulthood, fathers tend to encourage children to solve their stress or problems by themselves, while mothers tend to still provide help when children are distressed. These suggested hypotheses should be examined in future research.

Description
Dysregulated cortisol has been linked to a variety of adverse physical and psychological consequences. Stressors in the childhood family environment can influence cortisol activity throughout development. For example, research has shown that both infants and children of depressed mothers exhibit altered levels of cortisol compared to infants and children of non-depressed mothers. It is unclear, however, whether exposure to maternal depression in childhood and adolescence is related to cortisol activity at later stages of development. The current study examined the longitudinal relation between maternal depressive symptoms during late childhood (9-12 years old) and adolescence (15-19 years old) and cortisol activity in offspring in young adulthood (24- 28 years old) in a sample of 40 young adults and their mothers. Maternal depressive symptoms were prospectively assessed at four time points across the 15 year study. Cortisol samples were collected from young adult offspring at the final time point. Findings revealed that higher levels of maternal depressive symptoms during late childhood were associated with lower total cortisol output in young adulthood. Results suggest that attenuated cortisol levels, which put these young adults at risk for a variety of stress-related physical and psychological illnesses, may be a long-term consequence of exposure to maternal depression,. Depressive symptoms in mothers during their child's adolescence, however, did not relate to cortisol output. These findings suggest a sensitive period in late childhood during which the development of HPA activity may be susceptible to the environmental stressor of maternal depression.
