Behavioral and environmental correlates of infant abuse in group- living pigtail macaques

The present study investigated the context of occurrence of infant abuse and the behavior of abusive mothers and their infants in pigtail macaques (Macaca nemestrina). Subjects were 8 abusive mothers with their infants and 8 control mother-infant pairs living in 3 captive social groups. The most common forms of abuse were infant crushing and dragging and the most common context of occurrence was social stress. Severe and mild abuse differed in the frequency but not in the type of abuse patterns. Abusive mothers had controlling parenting styles relative to nonabusive mothers, and abused infants played at a later age and less frequently than controls. This study replicates previous findings on the parenting styles of abusive macaque mothers and provides new evidence on the context of occurrence of abuse and its consequences for infant health and social development.     

Intergenerational Transmission of Trauma-Related Distress: Maternal Betrayal Trauma,Parenting Attitudes,and Behaviors

The purpose of this study was to elucidate mechanisms involved in the intergenerational transmission of trauma-related distress. This study investigated whether betrayal trauma (BT; abuse by a person close to the victim) and specific parenting attitudes and behaviors among mothers with child abuse histories predicted internalizing and externalizing symptoms in their children. Mothers and children (ages 7–11) were recruited for a project on parenting and stress (N = 72). Maternal betrayal trauma predicted both internalizing (β = 0.33, p < .01) and externalizing symptoms (β = 0.25, p < .05) even when controlling for mothers’ trauma-related symptoms. Negative attitudes toward limit setting predicted externalizing symptoms (β = ?0.33, p < .05). Poorer communication (β = ?0.39, p < .05) but higher parenting satisfaction (β = 0.38, p < .01) predicted internalizing symptoms. These findings demonstrate the importance of assessing maternal trauma and parenting characteristics as part of interventions with symptomatic children.     

Individual,relationship, and context factors associated with parent support and pressure in organized youth sport

ObjectivesWe examined the association of multiple process, person, and context factors (Bronfenbrenner, 2005) with parents’ involvement (support and pressure) in sport. Specifically, we examined (a) the concordance among self, partner, and child reports of fathers and mothers for key study variables, and (b) prediction of parent support and pressure in youth sport by warmth and conflict in the parent–child relationship, parent positive and negative affect, and mastery and ego dimensions of the coach-created motivational climate.DesignCross-sectional survey.MethodSelf-reports of study variables were collected from athletes (ages 11–13 years) and parents from participating families (final N = 201). Multitrait-multimethod analysis was used to address the first study aim and multivariate multiple regression analysis for the second aim.ResultsValues for concordance among reporters were largely significant and in hypothesized directions, yet were of modest magnitude and suggested low reporter agreement (Cohen's κ range = −.07–.35). Multivariate relationships were significant and were of low to moderate magnitude (R_d range = .04–.22). Canonical loadings showed that warmth, positive affect, and mastery climate positively associate with support, whereas conflict, negative affect, and ego climate positively associate with pressure from fathers and mothers. Conflict and positive affect positively associated with support and pressure in some functions, suggesting complexity in interpretations of parent involvement.ConclusionFindings support the adaptive role of parent-child warmth, positive parent affect, and coach-created mastery motivational climate in youth sport; however, low concordance of reporter perceptions must be considered when pursuing family-related questions in sport.     

MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用：素质-压力假说与不同易感性假说的检验

抑郁的遗传与环境交互作用(G×E)机制已成为富有挑战性的前沿课题之一。然而,既有G×E研究大多关注遗传基因与不利环境的交互作用,相对忽视了积极环境的影响。本研究以1025名青少年为被试,运用问卷法与 DNA分型技术,采用间隔3年的追踪设计(T1小学六年级—T2初中三年级),考察 MAOA基因rs6323多态性与母亲支持性教养对青少年抑郁的交互作用以及性别在其中的调节作用,并同时采用新兴的探索性与验证性方法检验G×E交互作用的素质–压力假说与不同易感性假说。结果显示, MAOA基因rs6323多态性与母亲支持性教养行为交互作用于女青少年的抑郁,母亲支持性教养显著负向预测 GG 基因型女青少年的抑郁,但对 TT基因型女青少年抑郁的预测作用并不显著,该交互作用符合不同易感性假说。MAOA基因 rs6323多态性与母亲支持性教养对男青少年的抑郁无显著交互作用。本研究发现推进了抑郁遗传机制的研究,并为不同易感性假说提供新的研究证据。     

Effects of self-generated versus experimenter-provided cues on the representation of future events

Most experimental studies of prospection focused on episodic forms of future events prompted by means of verbal cues. However, there is evidence suggesting that future events differ considerably according to whether they are produced in response to external, experimenter-provided verbal cues or they are self-generated. In the present study, we compared the quality, the phenomenal characteristics, the temporal distribution, and the content of imagined events prompted by experimenter-provided cues (i.e., cue-words and short verbal sentences) or elicited by means of verbal cues that were self-generated in an autobiographical fluency task. The results showed that future events prompted by means of self-generated cues contained fewer event-specific details than future events prompted by experimenter-provided cues. However, future events elicited by means of self-generated and by experimenter-provided cues did not differ with respect to their phenomenal characteristics. The temporal distribution and the thematic content of future representations were also affected by the type of cue used to elicit prospection. These results offer a holistic view of the properties of future thinking and suggest that the content and the characteristics of envisioned future events may be affected by the method used to elicit prospection.     

The Relationship Between Parenting Style and Children's Adjustment: The Parents' Perspective

We examined the relationship between authoritative and authoritarian parenting styles and socio-emotional adjustment in elementary school children as reported from the parents' perspective. Mothers of first through fifth graders provided information about parenting style as well as children's competencies and problem behaviors. Teachers provided ratings of children's adjustment for a subset of the participants. Results indicated that authoritative parenting was associated negatively with parent- and teacher-rated maladaptive behavior, and positively with indicators of healthy adjustment. Correlations between authoritarian parenting and adjustment were either small or non-significant. Regression analyses indicated that authoritative parenting was more predictive of children's competence than maladaptation (22% versus 10% of variance). The effects of parenting style on adjustment were not moderated by demographic variables, such as the child's gender, grade level, ethnicity, and family income.     

Moderating Effects of Mothers' Attribution on the Relationships Between Their Affect and Parenting Behaviors and Children's Aggressive Behaviors

We examined Bugental's (1987) transactional model in the context of the relationships between aggressive children and their mothers. Based on Bugental's model, it was hypothesized that mothers who possessed the attributional style of low self-control and high child-control over hypothetical child care failure were more likely to manifest negative affect and negative parenting behaviors toward their child, only when their child is aggressive. Children's aggressive behavior was assessed via mothers' and teachers' ratings. Sixty-six children and their mothers served as subjects. Our results provided support for mothers' negative affect when using teachers' rating of children's aggressive behaviors only. Possible explanations for the differential results obtained using mothers' and teachers' ratings of children's aggressive behaviors were discussed.     

The Role of Parents and Peers in Early Adolescent Substance Use: An Examination of Mediating and Moderating Effects

We examined several models representing the relations among parenting practices, family structure, peer pressure, and drug use in a sample of 443 seventh graders. The setting was an urban school system serving a high percentage of African American students from low-income families. Analyses using structural equation modeling supported a mediation model in which both peer pressure and parenting practices had direct effects on drug use, with peer pressure mediating the influence of parenting. Within this model, family structure had a significant direct effect on parenting, however, contrary to hypotheses, children from two-parent families were more likely to report that they received adequate parenting than were children from single-parent extended families. Several gender differences were also found. Peer pressure was more highly related to drug use for girls than for boys, and the relation between parenting and peer pressure was stronger for boys. Examination of a model that included moderator effects revealed that the relation between peer pressure and drug use increased as a function of poor parenting. Results of our study underscore the importance of drug prevention efforts focused on parenting practices.
