Symposium on reciprocal influences in international psychology.

"The question of reciprocal influences was considered in terms of the number and distribution of psychologists throughout the world… . It was quickly conceded that, at present, influences in international psychology are not reciprocal and, perhaps, cannot be for some time to come. This problem is complicated not only by the sheer preponderance and resources of American psychology, but also by a general tendency to ignore attainments abroad, unless conveniently published in readily available English-language journals." Psychology "is an international science, to which psychologists everywhere can and do contribute… . We share a common enterprise with common goals and aspirations."

Prosocial behavior from early to middle childhood: Genetic and environmental influences on stability and change.

Prosocial behavior is important for the functioning of society. This study investigates the extent to which environment shared by family members, nonshared environment, and genetics account for children's prosocial behavior. The prosocial behavior of twins (9,424 pairs) was rated by their parents at the ages of 2, 3, 4, and 7 and by their teachers at age 7. For parent ratings, shared environmental effects decreased from .47 on average at age 2 to .03 at age 7, and genetic effects increased from .32 on average to .61. The finding of weak shared environmental effects and large heritability at age 7 was largely confirmed through the use of teacher ratings. Using longitudinal genetic analyses, the authors conclude that genetic effects account for both change and continuity in prosocial behavior and nonshared environment contributes mainly to change.

Sibling conflict in middle childhood predicts children's adjustment in early adolescence.

Associations between sibling conflict in middle childhood and psychological adjustment in early adolescence were studied in a sample of 80 boys and 56 girls. Parents and children provided self-report data about family relationships and children's adjustment. Parents' hostility to children was assessed from videotaped interactions. Results showed that sibling conflict at Time 1 predicted increases in children's anxiety, depressed mood, and delinquent behavior 2 years later. Moreover, earlier sibling conflict at Time 1 accounted for unique variance in young adolescents' Time 2 anxiety, depressed mood, and delinquent behavior above and beyond the variance explained by earlier maternal hostility and marital conflict. Children's adjustment at Time 1 did not predict sibling conflict at Time 2. Results highlight the unique significance of the earlier sibling relationship for young adolescents' psychological adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reciprocal influences between parents' marital problems and adolescent internalizing and externalizing behavior.

The present study examines reciprocal associations between marital functioning and adolescent maladjustment using cross-lagged autoregressive models. The research involved 451 early adolescents and their families and used a prospective, longitudinal research design with multi-informant methods. Results indicate that parental conflicts over child rearing predicted adolescent depressive symptoms and delinquency. In turn, these adolescent problems exacerbated parental conflicts over child rearing. Furthermore, conflict over child rearing served as the nexus through which more generalized marital dissatisfaction and adolescent adjustment problems were reciprocally interrelated. This research replicates earlier observations that marital problems intensify adolescent maladjustment and extends the literature by demonstrating that adolescent problems also predict marital conflict and ultimately marital dissatisfaction. In sum, the present study demonstrates that marital dissatisfaction, conflict over child rearing, and early adolescent adjustment difficulties are interwoven in a dynamic family system marked by reciprocity along these dimensions.

Impact of close family members on older adults' early response to depression treatment.

This study of 130 depressed older adults and their spouses or adult children examined the impact of caregiver burden specific to patients' depressive symptoms on patients' response to antidepressant treatment. Primary care patients completed medical, psychiatric, and neuropsychological assessments prior to treatment, and interviews were conducted with their identified family member. As hypothesized, caregivers' depression-specific burden predicted greater depression severity for the patient at the 6th week of treatment after accounting for patients' pretreatment characteristics, caregivers' depressive symptoms, and caregivers' relationship satisfaction. Future research may identify family attitudes and behaviors that stem from burden and compromise older adults' ability to recover from depression.

The self-system during childhood and adolescence: Development, influences, and implications.

Research on the development of the self-system is briefly reviewed, with a special focus on major themes and issues related to childhood and adolescence. Important tasks and characteristics of the self-system that emerge during infancy, toddlerhood, childhood, and adolescence are described, helping to illustrate the numerous factors that influence changing perceptions of the self. Relationships between the self-system and social agents also are described, showing the influence of schooling and parental involvement on the development of the self. Examples from the authors' research on the relationships between gender and the development of self-beliefs are reviewed. They include examples of atypical development throughout the article, and conclude with a discussion regarding the implications of developmental research for clinical practice.

Developmental structure of genetic influences on antisocial behavior across childhood and adolescence.

It is necessary to determine if causal influences on developing antisocial behavior change with age to guide both research and theory on its origins. The extent to which the same genetic factors influence antisocial behavior across 4–17 years of age was estimated using 2,482 sibling pairs of varying genetic relatedness. Assessments of antisocial behavior by mothers (4–9 years), mothers and youth (10–13 years), and youth (14–17 years) reflected the changing validity of informants across development. Genetic influences on antisocial behavior at 14–17 years were entirely shared with those on antisocial behavior at 10–13 years according to both informants. Genetic influences on antisocial behavior at 14–17 years were distinct from those at 4–9 years, however. These age differences in genetic influences cannot be fully distinguished from informant differences across age, but the present findings indicate that youth reported to be persistently antisocial during childhood and adolescence are influenced by one set of genetic factors influencing parent-report conduct problems in childhood and a second set of genetic influences on youth-reported delinquency that come into play around the time of the pubertal transition.

Anger expression and adaptation to childhood sexual abuse: The role of disclosure.

Previous research on anger and childhood sexual abuse (CSA) is largely cross-sectional and retrospective. In this study, we prospectively examined the consequences of expressing anger among sexually abused women in contexts of either voluntarily disclosing or not disclosing a previous abuse episode (n = 94). All CSA survivors in the study had documented histories of CSA. These participants and a matched, nonabused sample were asked to describe their most distressing experience while being videotaped to allow coding of anger expression. Approximately two thirds of the CSA survivors voluntarily disclosed a previous abuse experience. Participants completed measures of internalizing symptoms and externalizing symptoms at the time of disclosure and again two years later. The expression of anger was associated with better long-term adjustment (decreased internalizing and externalizing symptoms), but only among CSA survivors who had expressed anger while not disclosing an abuse experience. For CSA survivors who disclosed an abuse experience and for nonabused women, anger expression was unrelated to long-term outcome. These findings suggest that the benefits of anger expression for CSA survivors may be context specific. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Environmental risk factors and children's achievement from middle childhood to early adolescence.

This study examined the long-term effects of low family income and stressful life events on math and reading achievement test percentile scores for 1,253 children. Four birth cohorts were followed for 2-4 years so that achievement across Grades 2 through 7 could be examined. Two types of analytic models, the multiplicative risk factor model and the cumulative risk model, were used. The moderating effects of ethnicity and gender were also explored. The results suggest that low income and minority ethnic status are significant risk factors for children's achievement. No systematic evidence was found for a large impact of life events on reading achievement, and the effects of such events on math achievement appear to be best understood as part of the larger context of multiple risk factors during childhood. The findings suggest a differential impact of risk factors on math achievement compared with reading achievement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social influences in motivated drinking among college students.

This study tested whether drinking motives mediate the relation between personality and alcohol use and whether these predictors affected drinking in these individuals' friends. College students and their friends participated in the study as dyads (n=43 dyads, 86 participants). Each person completed surveys and a 28-day experience sampling protocol. Structural equation analyses found that (a) social motives mediated the relation between extraversion and alcohol outcomes, (b) coping motives mediated the relation between neuroticism and alcohol outcomes, and (c) enhancement motives mediated the relation between extraversion and alcohol outcomes. Moreover, young adults' alcohol use, but not their problem use, was influenced by their own drinking motives as well as the drinking motives of their best friends.

Reciprocal relations between adolescent substance use and delinquency: A longitudinal latent variable analysis.

Reciprocal relations between self-reported substance use and delinquency were examined through the analysis of 4-wave panel data collected from 1,218 high school students. A longitudinal, latent-variable framework was used to investigate interrelationships between changing patterns of generalized involvement in these 2 problem behaviors, while simultaneously accounting for specificity in drug use (e.g., marijuana use) and delinquency (e.g., theft). Analyses revealed that a model of bidirectional effects between polysubstance use and general delinquency was plausible for boys but not for girls. For boys, the effect of delinquency on substance use was small but consistent over time, whereas the effect of substance use on delinquency was larger but restricted to the earlier waves of the study. Implications for the question of whether or not substance use and delinquency have causal connections are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-efficacy and performance in mathematics: Reciprocal determinism in 33 nations.

Reciprocal determinism is a central premise of Bandura's (1986) social cognitive theory. Studies of the relationship between self-beliefs and performance tend to draw on this or related theories and usually endorse the notion of reciprocal determinism at a substantive–theoretical level. However, attempts to model this postulated mutual influence of self-beliefs and performance are few and are focused on the relationship between self-concept and performance. The reciprocal determinism of self-efficacy and performance seems to be without direct empirical support, probably because the longitudinal, repeated-measures data often considered necessary for this purpose are not available. It is possible, though, to model reciprocal effects with cross-sectional data. In the analyses reported in this article, the authors achieved this using a structural equation model in which the mutual influence of self-efficacy and performance in mathematics is represented as a feedback loop. This model was estimated in each of 33 nations on the basis of data on the mathematics self-efficacy and mathematics achievement of 15-year-olds. The model was a good fit to the data in 30 nations and was supportive of reciprocal determinism in 24 of these, suggesting a fundamental psychological process that transcends national and cultural boundaries.

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior.

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior were examined in a large community sample of 6,383 adult male, female, and opposite-sex twins. Retrospective reports of childhood conduct disorder (prior to 18 years of age) were obtained when participants were approximately 30 years old, and lifetime reports of adult antisocial behavior (antisocial behavior after 17 years of age) were obtained 8 years later. Results revealed that either the genetic or the shared environmental factors influencing childhood conduct disorder differed for males and females (i.e., a qualitative sex difference), but by adulthood, these sex-specific influences on antisocial behavior were no longer apparent. Further, genetic and environmental influences accounted for proportionally the same amount of variance in antisocial behavior for males and females in childhood and adulthood (i.e., there were no quantitative sex differences). Additionally, the stability of antisocial behavior from childhood to adulthood was slightly greater for males than females. Though familial factors accounted for more of the stability of antisocial behavior for males than females, genetic factors accounted for the majority of the covariation between childhood conduct disorder and adult antisocial behavior for both sexes. The genetic influences on adult antisocial behavior overlapped completely with the genetic influences on childhood conduct disorder for both males and females. Implications for future twin and molecular genetic studies are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Individual and familial influences on the onset of sexual intercourse among urban African American adolescents.

A sample of 198 African American families, living in urban poverty, participated in a longitudinal study of adolescent sexual development beginning when children were in the 4th or 5th grade. Self-reports of family conflict and pubertal development and videotaped family interaction data were collected at 2 time points approximately 2 years apart. Youths reported on sexual debut at each time point. More boys than girls reached sexual debut early. Greater levels of family conflict predicted early sexual debut. Observational data indicated more developed preadolescents with greater family conflict and less positive affect were least likely to delay debut. Changes in pubertal development and observed family conflict were associated with early debut. Possible mediating mechanisms and implications for preventive interventions are discussed.

Behavioral inhibition: Stability and associations with adaptation from childhood to early adulthood.

The stability of individual differences in behavioral inhibition and their association with peer relations, emotional distress, and life-course timing were examined in a longitudinal study of 205 individuals from childhood (ages 8–12) to early adulthood (ages 17–24). Behavioral inhibition was conceptualized as stranger wariness and measured through ratings made by interviewers following individual interview or testing sessions. Individual differences in behavioral inhibition were consistent from childhood to early adulthood (r?=?.57). In early adulthood, higher behavioral inhibition was associated with a less positive, less active social life for both sexes and, for men, with greater emotional distress and negative emotionality. For both genders, participants who were inhibited as children were less likely to have moved away from their family of origin by the early adulthood assessment.

"Do as I say, not as I do": Family influences on children's safety and risk behaviors.

Objective: Although there is considerable speculation that family-based socialization processes influence children's safety and risk behaviors, few studies have addressed this important issue. The present study compared the impact of parent practices and teaching about safety on children's current behaviors and their intended future behaviors when they reach adulthood. Design and Measures: Children 7 to 12 years of age were interviewed and asked to report on their parents' practices and teachings (discussions, expectations for children's behavior) regarding five common safety behaviors. As well, the children reported on their own current practices and how they intended to behave when an adult. When appropriate, they provided explanations about why their parents engage in fewer safety behaviors than they required of their children. Results: Children's current behavior was best predicted by parental teaching, however, how children planned to behave when they were adults was best predicted by parents' practices. Children attributed less frequent safety behaviors by their parents than themselves to general attributes of adults and their parent having special skills that made the safety practices less necessary than was true for children. Conclusion: These results highlight family influences on children's adoption of safety and risk practices and support the notion of intergenerational transmission of risk behaviors.

Examination of the mediational influences of peer norms, environmental influences, and parent communications on heavy drinking in athletes and nonathletes.

The present study used perspectives from the general literature on college alcohol consumption to examine mediational influences of peer, environmental, and parental variables on heavy drinking for student athlete and nonathlete samples. Eight hundred thirty-five freshmen who differed in organized sports involvement were compared on heavy drinking outcomes, peer norms, environmental influences, and parental communication. College athletes reported significantly more heavy drinking experiences than nonathletes. Peer norms, environmental influences, and parental communication were all significant mediators of the athlete-heavy drinking relationship. Athletes reported a higher perception of peer drinking, peer approval of drinking, higher alcohol availability, and direct drink offers, which, in turn, were related to higher rates of heavy drinking. Parental communication mediated the athlete-heavy drinking relationship differently, depending on the specific topic of conversation. Discussion surrounding the importance of incorporating a variety of interventions aimed at reducing collegiate athlete drinking on the basis of the peer, environmental, and parental influences observed in the present analyses are presented. Limitations and directions for future research are also noted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Temporal associations of cigarette smoking with social influences, academic performance, and delinquency: A four-wave longitudinal study from ages 13-23.

This study examined the temporal associations of cigarette smoking with prosmoking social influences, academic performance, and delinquency in a cohort of 6,527 adolescents surveyed at ages 13, 16, 18, and 23 years. Prosmoking peer and family influences were risk factors for future smoking throughout adolescence, with family influences perhaps also operating indirectly through the adolescent's exposure to prosmoking peers. There were reciprocal associations of youth smoking with parental approval, peer smoking, and poor grades (but not delinquency), with youth smoking emerging as a stronger antecedent than consequence of these psychosocial factors. Few gender differences in these associations were observed. Implications of these findings for efforts to prevent youth smoking are discussed.

Genetic and environmental influences on interpersonal cognitions and associations with depressive symptoms in 8-year-old twins.

Less is known about depression in children than in adults. This study integrates fields by combining cognitive and interpersonal research investigating childhood depression symptoms through the use of a genetic framework. Three research questions are addressed. First, what are the associations among interpersonal cognitions, anxiety, and depression? Second, what are the relative magnitudes of genetic and environmental influences on interpersonal cognitions? Third, to what extent do genetic and environmental influences explain associations between interpersonal cognitions and depression? Three hundred pairs of 8-year-old twins reported on symptoms of depression and anxiety by completing the Children's Depression Inventory and the Screen for Childhood Anxiety-Related Emotional Disorders. The authors examined interpersonal cognitions with the Children's Expectation of Social Behaviors and the Perceptions of Peers and Self Questionnaires. Interpersonal cognitions were more strongly correlated with depression (mean r = .35) than with anxiety (mean r = .13). Genetic influence on interpersonal cognitions was small (M = 3%), and associations between interpersonal cognitions and depression were mainly explained by environmental influences. These latter findings may result from interpersonal cognitions in young children, reflecting life experiences as opposed to trait-like cognitive biases.

Environmental and genetic influences on prereading skills in Australia, Scandinavia, and the United States.

Individual differences in measures of prereading skills and in questionnaire measures of 4-5-year-old twins' print environments in Australia, Scandinavia, and the United States were explored with a behavioral-genetic design. Modest phenotypic correlations were found between environmental measures and the twins' print knowledge, general verbal ability, and phoneme awareness. Lower print knowledge in Scandinavian twins was related to country differences in preschool print environment. Latent-trait behavioral-genetic analyses indicated very strong shared-environment influences on individual differences in Print Knowledge. Genetic influence was also significant. Several other prereading skills varied in their environmental and genetic influence, including a significant contrast between Phonological Awareness and Print Knowledge. Rapid Naming also revealed very strong genetic influence, as did Verbal Memory. Stronger shared-environment influences were found for Vocabulary and Grammar/Morphology. Genetic and environmental correlations among latent traits for General Verbal Ability, Phonological Awareness, and Print Knowledge were high, but there were also significant independent genetic and environmental contributions to each skill. Practical implications include the need for substantial and sustained instructional support for children hampered by genetic constraints on early literacy development.
