Multilevel covariance structure analysis of sibling substance use and intrafamily conflict

Conventional covariance structure analysis, such as factor analysis, is often applied to data that are obtained in a hierarchical fashion, such as siblings observed within families. A more appropriate specification is demonstrated which explicitly models the within-level and between-level covariance matrices of sibling substance use and intrafamily conflict. Participants were 267 target adolescents (mean age=13.11 years) and 318 siblings (mean age=15.03 years). The level of homogeneity within sibling clusters, and heterogeneity among families, was sufficient to conduct a multilevel covariance structure analysis (MCA). Parental and family-level variables consisting of marital status, socioeconomic status, marital discord, parent use, and modeling of substances were used to explain heterogeneity among families. Marital discord predicted intrafamily conflict, and parent marital status and modeling of substances predicted sibling substance use. Advantages and uses of hierarchical designs and conventional covariance structure software for multilevel data are discussed.     

The Double Bind of Siblings in Adolescent Substance Abuse Treatment

Siblings have been found to be perhaps the greatest source of social risk for adolescent substance abuse, particularly when the relationship is close. But, close sibling relationships are also linked to an array of important developmental and lifelong protective benefits. Sibling closeness simultaneously poses considerable risks and benefits. These conflicting findings suggest opposite treatment directions, or a “double bind” for practice. That sibling closeness risks contagion suggests treatment that aims to decrease sibling closeness. On the other hand, the many lifelong and protective benefits of close sibling relationships suggests increasing sibling closeness when possible. Family-based treatment is recommended for adolescent substance abuse, but offers little explicit direction for involving siblings in general, and none for this double bind. This paper untangles and translates the extant literature into preliminary practice guidelines; the Sibling Substance Abuse Treatment Matrix. Important variations related to gender, and age-spacing are considered. Implications for future research and practice are discussed.     

Perpetration of sibling aggression and sibling relationship quality in emerging adulthood

This study examined how emerging adults' perpetration of aggression toward a sibling closest in age was longitudinally associated with their sibling relationship quality. Emerging adults (N = 143; M_age = 19.62; 70% female) completed surveys online or by mail at two time points, 4 years apart. Of emerging adults, 25% perpetrated aggression against their closest‐in‐age sibling. Perpetration of sibling aggression was predictive 4 years later of less sibling warmth, involvement, and emotional help. None of the interactions with gender and sibling gender was significant. This study's findings demonstrate the importance of examining the consequences of perpetration of aggressive behavior toward a sibling for sibling relationship quality in emerging adulthood.     

Older sibling correlates of younger sibling drug use in the context of parent-child relations

The purpose of this study was to examine older brother correlates of younger brother drug use in the context of parental influences and younger brother personality. The sample consisted of 278 White male college students and their oldest brothers, who volunteered to answer self-administered questionnaires. Results indicated that 3 domains of influence each had an independent impact on younger brother drug use: (a) parent-younger brother relationships and parent drug use, (b) older brother-younger brother relationships and older brother drug use, and (c) younger brother personality. Modeling of nondrug use and a strong attachment relationship in the parent-younger brother and sibling dyads, as well as younger sibling traits of conventionality, had strong links to low younger brother drug use. Our findings highlight the importance of modeling and mutual parent-child attachment relationships as well as sibling relationships as they relate to the possible etiology of drug use.     

Effects of task difficulty on sibling teaching in middle childhood

Teaching styles were investigated in 28 middle‐class sibling dyads (older sibling M age = 8.2 yrs; younger sibling M age =5.11 yrs) using two sets of block design tasks (five easy; five hard). Older siblings employed a greater number of strategies (i.e. physical demonstrations, scaffolding, corrective feedback) in the hard than in the easy tasks, thus demonstrating the ability to adjust teaching strategies according to task difficulty. Teachers also employed more frequent strategies when learners were younger indicating that they may be sensitive to developmental differences. In the hard tasks, learners responded positively to teacher guidance, but were also more likely to reject the teacher's help, perhaps demonstrating responsibility for their own learning. Findings are discussed in light of current social‐cognitive approaches highlighting the important roles of both teacher and learner during episodes of sibling teaching in middle childhood.

Affect and peer context interactively impact adolescent substance use

Risk factors, such as emotional distress and peer substance involvement, are often tested as competing influences on adolescent substance use. However, the current study examined how affect (both positive and negative) and peers (both in terms of relationship quality and substance involvement) are interactive influences on adolescent substance use. A sample of 398 high school juniors and seniors completed surveys assessing each of these domains. Results of hierarchical regression analyses showed strong associations between an adolescent's and his or her best friend's substance use. Complex interactions supported the study hypothesis in that relations between affect and adolescent substance use were context dependent, with some peer contexts enhancing risk for substance use and others dampening this risk. Implications of these findings for interventions and preventions concerning adolescent substance use are discussed.     

Direct and indirect transmission of relationship functioning across generations

Relationship functioning is assumed to propagate across subsequent generations, but most studies have lacked appropriate methodologies to test this assumption prospectively. In a randomly selected sample of youth (N = 821) followed prospectively for over 25 years across multiple generations, we examined the association of romantic engagement (i.e., emotional involvement and closeness) between parents with offspring romantic relationship quality. We tested two developmental pathways linking parents' romantic engagement with offspring adult romantic relationship quality, the first operating via parenting practices, and the second operating via adolescent depression. Parents' romantic engagement predicted offspring romantic relationship quality a mean of 17 years later, net age and socioeconomic status. Results supported a developmental pathway from parents' romantic engagement at offspring mean age 14, to parenting at offspring mean age 16, to offspring socioemotional functioning at mean age 22, and offspring romantic relationship quality at mean age 33. However, the influence of parents' romantic engagement on offsprings' adult romantic relationship quality does not appear to operate via a pathway of adolescent depression. Implications for prevention are discussed.     

The influence of social environment and social image on adolescent smoking.

This purpose of this article is to explore differences by gender and school grade in patterns of association among social influences and tobacco use. Data from the 1999 (N = 15,038) and 2000 (N = 35,828) National Youth Tobacco Survey (American Legacy Foundation, 1999, 2000), a nationally representative, repeated cross-sectional survey, were used in the analysis. The authors compared effects on adolescent smoking. Direct paths from social environment to current smoking increased from middle school to high school. Indirect paths with social image mediating this relationship revealed a smaller increase. The pattern was constant across subsamples. Social image of smokers mediated the influence of social environment on adolescent smoking. Social image had a greater effect on smoking among middle school boys and high school girls.     

A Multivariate Associative Finite Growth Mixture Modeling Approach Examining Adolescent Alcohol and Marijuana Use

Theoretical and empirical substance use development research suggests that adolescent populations are not homogenous and can often be separated into subpopulations characterized by qualitatively different patterns of substance use development. This paper demonstrates the application of a multivariate associative finite latent growth mixture modelling approach to examine heterogeneity in patterns of adolescent alcohol and marijuana use and the influence of age, gender, parent, and peer substance use. Substance use problem outcomes were also examined. Participants were male and female adolescents (N = 1,044) ranging in age from 11 to 17 years at the first assessment (Mean age = 14.47; SD = 1.95). Individuals were 45% female and 82% Caucasian. Using growth mixture methodology, a 7-class model captured distinct simultaneous alcohol and marijuana use patterns over a 3-year period. Findings highlight the importance of examining subgroups of adolescent substance use, rather than focusing only on single samples.     

Familial influences on television viewing and aggression: A sibling study

Familial influences on aggressive behavior and TV viewing were investigated in a survey of adolescent siblings. Same-sex siblings resembled one another in aggression (brothers, r = 0.59; sisters, r = 0.52) and in their exposure to violent TV programs; opposite-sex siblings were dissimilar. Within individuals, the frequency of watching crime and action programs correlated nonsignificantly with aggression. Two other variables, however, were associated with aggression: identification with aggression and aggression consequences. These relationships also held up between families (BF, covariance of sibling' averages) and within families (WF, covariance of sibling' differences). The latter WF relationship indicated that one sibling was typically the more extreme on both aggression and its correlate than a brother or sister. These results were interpreted in light of behavioral genetic data that suggest substantial genetic influences, few common environmental influences, and large within-family environmental influences on personality development.     

Adolescent Substance Use: Preliminary Examinations of School and Neighborhood Context

In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are organized to provide educational services to students who share similar educational abilities and behavioral repertoires. The resulting segregation of students into these settings may result in different school norms for substance use. Similarly, neighborhood resources, including models for substance use and drug sales involvement, may play an important role in adolescent substance use. We briefly review literature examining contextual influences on adolescent substance use, and present results from two preliminary studies examining the contribution of school and neighborhood context to adolescent substance use. In the first investigation, we examine the impact of familial, peer, and school contexts on adolescent substance use. Respondents were 283 students (ages 13 to 18) from regular and special education classrooms in six schools. Although peer and parental contexts were important predictors of substance use, school norms for drug use accounted for variance in adolescent use beyond that explained by peer and parental norms. Data from a second study of 114 adolescents (mean age = 15) examines neighborhood contributions to adolescent substance use. In this sample, neighborhood indices did not contribute to our understanding of adolescent substance use. Implications for prevention are presented.     

Gender differences in the development of relationships during late adolescence

Until recently, inadequate measures of affiliation need and relationship closeness hindered investigations into the social development of adolescents. For example, assumptions about gender differences (Douvan & Adelson, 1966; Gilligan, 1982) and age-related changes (Dunphy, 1972; Erikson, 1968; Newman & Newman, 1976) in affiliation need and relationship closeness have remained virtually untested. To better understand adolescent social behavior and test these assumptions, recently developed measures of affiliation need and interpersonal closeness were used to examine seventy-four 18- to 20-year-olds. In support of Erikson's theory, need for social comparison declined with age for both sexes. However, in support of Gilligan's theory, not only were females more attached to their partners, but these gender differences were most pronounced for the 18-year-olds. Finally, Dunphy's (1972) assumption that adolescents' need for stimulation peaks around age 18 or 19 and then declines, and Newman and Newman's (1976) position that need for emotional support declines in later adolescence, held true--but only for females.     

Parental and sibling effects in adolescent outcomes

This study examined the differential effects of parenting and sibling influences (and the interaction between the two) in predicting adolescents' problem behaviors. The reliability and validity of the Sibling Relationship Questionnaire was also assessed. Subjects were 99 intact families from the San Francisco Bay area, all of whom contained both parents and at least one target child between 10 and 18 years of age still living in the home. Analysis indicated that sibling behavior was a significant predictor of deviant behavior, as measured by the Child Behavior Checklist, even when parenting effects were statistically controlled. Parenting effects had a separate effect on adolescents' positive behaviors. The analysis of the Sibling Relationship Questionnaire indicated adequate test-retest and internal consistency reliability, and construct validity. Findings are discussed in terms of the larger literature on socialization on the different ways that siblings and parents influence adolescent outcomes.     

Longitudinal direct and indirect pathways linking older sibling competence to the development of younger sibling competence

A 4-wave longitudinal model tested direct and indirect links between older sibling (OS; M = 11.7 years) and younger sibling (YS; M = 9.2 years) competence in 152 rural African American families. Data were collected at 1-year intervals. At each wave, different teachers assessed OS competence, YS competence, and YS self-regulation. Mothers reported their own psychological functioning; mothers and YSs reported parenting practices toward the YS. OS competence was stable across time and was linked with positive changes in mothers' psychological functioning from Wave 1 to Wave 2. Mothers' Wave 2 psychological functioning was associated with involved-supportive parenting of the YS at Wave 3. OS Wave 2 competence and Wave 3 parenting were indirectly linked with Wave 4 YS competence, through Wave 3 YS self-regulation. Structural equation modeling controlled for Wave 1 YS competence; thus, the model accounted for change in YS competence across 3 years.     

School Substance Use Norms and Racial Composition Moderate Parental and Peer Influences on Adolescent Substance Use

Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid‐western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school‐level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School‐level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school‐level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use.     

Marital closeness,autonomy, mastery,and depressive symptoms in a U.S. Internet sample

This Internet survey tests a theory that meeting needs through marital closeness (naming spouse confidant and emotional support; perceiving oneself to be named both by the spouse; and sexual satisfaction), autonomy, and mastery protects against depressive symptoms. The U.S. sample includes 1,163 relatively wealthy and educated married respondents aged 19–84 years. The regression model, controlling for sociodemographic factors, social integration, self‐rated health, and gender interactions, explained more than half the variability in respondents’ depressive symptoms. Regardless of age, wives who were closer to their husbands were less depressed than those who were less close. Older husbands were less depressed than younger ones. Marital closeness was protective for husbands at all ages with its absence particularly problematic at younger ages.     

Israeli kindergarten children's gender constancy for others' counter‐stereotypic toy play and appearance: the role of sibling gender and relative age

To test divergent theoretical predictions as to the impact of having a younger or older, same‐sex sibling or opposite‐sex sibling on other gender constancy, Israeli kindergarten children in two‐child families responded to a gender constancy task in which a male and female picture target engaged in counter‐stereotypic toy play and adopted counter‐stereotypic appearance. Children were also asked whether the target child could change sex at will and to explain the difference between boys and girls. Relative age of sibling, both independently and in interaction with participant sex, was associated with greater gender constancy in the face of counter‐stereotypic toy play. Relative age of sibling and sibling sex was independently associated with greater gender constancy in the face of counter‐stereotypic appearance. In both cases, children with a younger sibling evidenced greater gender constancy. Boys, especially ones with a male sibling, referred most explicitly to target's birth sex in accounting for his or her being unable to change sex at will. Genital and anatomical differences between boys and girls were cited more often by children who referred explicitly to target's birth sex and had a younger sibling. The results were discussed in the context of theories of gender development and the socialization of gender within the family. Copyright © 2008 John Wiley & Sons, Ltd.     

Situational affect and temperament: Implications for sibling caregiving

The caregiving behaviour of 60 preschool‐age children (M=50 months) toward their 16‐month‐old younger siblings was observed during a brief separation from their parents. Sibling caregiving was more strongly associated with parent ratings of both the older siblings' and toddlers' temperament than with the younger siblings' distress exhibited during the separation. The older siblings' social fear was positively related to providing care, whereas their temperamental activity level was negatively related to caregiving. Younger siblings' temperamental anger and soothability were positively associated with receiving care from an older sibling. Relations with temperament were independent of both children's distress levels during the separation, and in several instances, dispositional affective measures (i.e. temperament) made stronger contributions to the prediction of sibling caregiving than did situational distress.

The Role of the Family in Promoting Responsible Substance Use in Adolescence

The aim of this study was to examine the role of family dimensions in tobacco, alcohol, and cannabis use among adolescents. Furthermore, we investigated how demographic variables (adolescents’ gender and age) influence substance use and moderate the relationship between family dimensions and substance use. The sample consisted of 14,825 adolescents aged 13–14, 15–16, and 17–18 who participated in the 2006 edition of the Health Behaviour in School-aged Children (HBSC) study in Spain. The HBSC-2006 questionnaire included demographic variables (gender and age), substance use variables (tobacco, alcohol, and cannabis use), and family dimensions (parental affection, parental promotion of autonomy, family activities, adolescent disclosure, parental solicitation, and parental knowledge). The results indicated that adolescent disclosure, family activities, and parental knowledge had a significant effect on substance use. Specifically, maternal variables were shown to be slightly more relevant than paternal variables. Additionally, substance use was higher in older adolescents than in younger adolescents, and boys smoked less than girls. The discussion focused on how family dimensions promoted responsible substance use in adolescence.     

Adolescents in Residential Treatment: Caregiver and Peer Predictors of Risk Behavior and Academic Performance

The purpose of this research was to better understand the substance use and sexual risk taking behavior among high-risk adolescent populations placed in residential treatment facilities, including those in the foster care and juvenile justice systems. The primary predictors considered in this study included caregiver support, caregiver closeness, other adult support, adolescent self-disclosure/communication with caregiver, caregiver expectations about sexual behavior, and peer influence regards to drugs/alcohol and sexual behavior. Participants included 120 adolescent females in grades 7 to 12 (median grade?=?10; mean age 15.7 years), primarily African American (57.2 %) and White (29 %), in a residential treatment setting in a large urban area in the Midwest. Caregiver support and self-disclosure/communication with caregivers predicted condom use at most recent intercourse, but variables related to substance use were most consistently predictive of sexuality variables including onset and frequency of behavior. None of these support variables significantly predicted onset and frequency of substance use. Caregiver support was the contributing variable in predicting academic achievement.
