Differential susceptibility and the early development of aggression: interactive effects of respiratory sinus arrhythmia and environmental quality

The purpose of the current study was to predict the development of aggressive behavior from young children's respiratory sinus arrhythmia (RSA) and environmental quality. In a longitudinal sample of 213 children, baseline RSA, RSA suppression in response to a film of crying babies, and a composite measure of environmental quality (incorporating socioeconomic status and marital adjustment) were measured, and parent-reported aggression was assessed from 18 to 54 months of age. Predictions based on biological sensitivity-to-context/differential susceptibility and diathesis-stress models, as well as potential moderation by child sex, were examined. The interaction of baseline RSA with environmental quality predicted the development (slope) and 54-month intercept of mothers' reports of aggression. For girls only, the interaction between baseline RSA and environmental quality predicted the 18-month intercept of fathers' reports. In general, significant negative relations between RSA and aggression were found primarily at high levels of environmental quality. In addition, we found a significant Sex × RSA interaction predicting the slope and 54-month intercept of fathers' reports of aggression, such that RSA was negatively related to aggression for boys but not for girls. Contrary to predictions, no significant main effects or interactions were found for RSA suppression. The results provide mixed but not full support for differential susceptibility theory and provide little support for the diathesis-stress model.     

Development and psychometric evaluation of the Personal Growth Initiative Scale-II

The original Personal Growth Initiative Scale (PGIS; Robitschek, 1998) was unidimensional, despite theory identifying multiple components (e.g., cognition and behavior) of personal growth initiative (PGI). The present research developed a multidimensional measure of the complex process of PGI, while retaining the brief and psychometrically sound properties of the original scale. Study 1 focused on scale development, including theoretical derivation of items, assessing factor structure, reducing number of items, and refining the scale length using samples of college students. Study 2 consisted of confirmatory factor analysis with 3 independent samples of college students and community members. Lastly, Study 3 assessed test-retest reliability over 1-, 2-, 4-, and 6-week periods and tests of concurrent and discriminant validity using samples of college students. The final measure, the Personal Growth Initiative Scale-II (PGIS-II), includes 4 subscales: Readiness for Change, Planfulness, Using Resources, and Intentional Behavior. These studies provide exploratory and confirmatory evidence for the 4-factor structure, strong internal consistency for the subscales and overall score across samples, acceptable temporal stability at all assessed intervals, and concurrent and discriminant validity of the PGIS-II. Future directions for research and clinical practice are discussed.     

Abused Conservative Christian Wives: Treatment Considerations for Practitioners

Through narrative, the authors explore the faith‐based challenges of a physically and emotionally abused Conservative Christian wife to illustrate her ideological assessment of agency in a violent marriage and her concerns about the religious consequences of escape. To offset religious teachings that obstruct the safety and self‐assertion of abused Conservative Christian wives, the authors offer practitioners practical, idiomatic recommendations through which clients can reassess the limitations of common religious schemas, including conceptions of wifely submission, marital permanence, infinite forgiveness, and pious suffering. The religious community's responses to abused wives, particularly those of the clergy, are also discussed.     

Family emotion expressivity,emotion regulation,and the link to psychopathology: Examination across race

Research has established links between parental emotion socialization behaviours and youth emotional and psychological outcomes; however, no study has simultaneously compared these relations for White, Black, and Asian individuals. In this study, emerging adults identifying as White (n= 61), Black (n= 51), or Asian (n= 56) retrospectively reported on parents’ emotion socialization behaviours during childhood, existing emotion regulation (ER) skills, and current psychopathology symptoms. Asian participants reported fewer positive displays of emotions in their families during childhood than White and Black participants. Despite this difference, low expression of positive emotions in families during childhood did not relate to negative outcomes for Asian participants but was linked for White and Black participants. Overall, Asian participants reported more difficulties with ER than Black or White participants, and relations between ER difficulties and psychopathology varied by racial group. The findings emphasize the need to consider race when conducting research on emotion functioning with families and highlight emotion dysregulation as a potential treatment target for White, Black, and Asian individuals.     

Survival skills and ethics training for graduate students: A graduate student perspective

Graduate students in the sciences must develop practical skills geared toward scientific survival and success. This is particularly true now, given the paucity of research funds and jobs. Along with more elementary skills, research ethics should be an integral part of students’ scientific training. Survival skills include research skills, communication skills, general efficiency, and preparation for post-graduate work. Ethics training covers guidelines for use of animal and human subjects, data treatment, disclosure, credit issues, conflicts of interest, and response to misconduct. The objective of this paper is to describe, from a graduate student’s perspective, the need for survival and ethics training in graduate programs and to raise both faculty and student awareness of the possibilities for explicit instruction of these skills. Many survival skills and ethical practices will be learned without explicit direction and some are already part of standard training; but, this is not the case for all students or for all skills, so specific instruction is a necessity. Research faculty can use their own experience to help students to develop the proficiencies they will need to succeed.     

Experience of pregnancy and delivery as predictors of postpartum depression

This research examined experiences of pregnancy and delivery as predictors of three subscales identified within the Edinburgh Postnatal Depression Scale (nonspecific depression, anhedonia, and anxiety). Mothers of babies under 1 year (N = 415) completed the Edinburgh Postnatal Depression Scale (EPDS) and gave information as to number of pregnancies, number of children, and their ratings of the difficulty of the course of pregnancy and delivery. Number of pregnancies and number of children did not predict scores on any of these subscales. Difficulty in the course of pregnancy was a significant positive predictor of nonspecific depression, and difficulty of delivery was a significant positive predictor of anxiety. Neither of these variables significantly predicted anhedonia. These results provide evidence of the heterogeneity of postpartum depression, indicating that risk factors differentially influence subscales of the EPDS.     

From "in the air" to "under the skin": cortisol responses to social identity threat

The authors examined women's neuroendocrine stress responses associated with sexism. They predicted that, when being evaluated by a man, women who chronically perceive more sexism would experience more stress unless the situation contained overt cues that sexism would not occur. The authors measured stress as the end product of the primary stress system linked to social evaluative threat-the hypothalamic-pituitary-adrenal cortical axis. In Study 1, female participants were rejected by a male confederate in favor of another male for sexist reasons or in favor of another female for merit-based reasons. In Study 2, female participants interacted with a male confederate who they learned held sexist attitudes or whose attitudes were unknown. Participants with higher chronic perceptions of sexism had higher cortisol, unless the situation contained cues that sexism was not possible. These results illustrate the powerful interactive effects of chronic perceptions of sexism and situational cues on women's stress reactivity.     

The role of graded category structure in imaginative thought

Participants generated lists of exemplars from the categories of animals, tools, and fruit, and their lists were used to determine the relative accessibility of individual exemplars. Measures of accessibility included output dominance (the number of participants who listed an exemplar), rank (how early instances were listed), and two scores that reflect their combination-output precedence and dominance/rank. Other participants drew and described novel exemplars of those categories that might exist on an imaginary planet and reported on the factors that influenced their creations. References to Earth animals, tools, or fruit were used to determine imagination frequency (the number of participants who mentioned relying on particular Earth exemplars). Items high in accessibility were also high in imagination frequency, implying that those items that come to mind most readily are the ones most likely to serve as starting points for the development of novel ideas. This result held even when task constraints weighed against the use of such items (Experiment 2) and when participants were encouraged to be as creative as possible (Experiment 4), suggesting that it is difficult to avoid the influence of highly accessible category exemplars. Other measures of category structure, including the rated typicality, familiarity, and frequency of exemplars, did not predict imagination frequency as well. The results are discussed in terms of expanding concept boundaries and the inadvertent application of knowledge that is readily accessible.
