Testing a Model of Universal Prevention Effects on Adolescent Relationships and Marijuana Use as Pathways to Young Adult Outcomes

There are several interrelated knowledge gaps in the literature on skills-building interventions for middle schoolers designed to prevent initiation of substance use, all of which concern the limited study of the adolescent pathways of those intervention effects on distal young adult outcomes. Among the most important yet understudied pathways of influence on long-term effects are positive youth relationship outcomes of middle-school interventions. Other influential pathways for long-term effects are reductions in adolescent substance misuse, particularly marijuana use, considering the long-term consequences of early marijuana initiation. To address these knowledge gaps, data from a randomized controlled trial were used to test a longitudinal, developmental model positing pathways of intervention effects on age 21 illicit drug use and positive relationship affect, via earlier effects on adolescent relationships and marijuana use. Sixth-graders and their families enrolled in 22 Iowa schools were randomly assigned to the Iowa Strengthening Families Program or a control group (N?=?446). The average age of students at baseline was 11.3 years (10–13 year age range); 48% were male and 98% were Caucasian, reflective of the demographics in the participating rural Midwest communities. Measures included middle-school relationships (parents, peers, school), high school marijuana use, plus age 21 illicit drug use and relationship affect (parents, work, school), 10 years past intervention implementation. As expected, intervention effects on young adult variables were indirect, through effects on adolescent outcomes, with higher-risk participants showing greater intervention impact. The findings suggest preventive interventions with young adolescents have potential to demonstrate effects into young adulthood.

     

Adolescent Stressors,Coping Strategies,and Psychological Health Studied in the Family Context

The present study examined adolescents' stressors, coping, and psychological health in the family context in 42 adolescents, ranging in age from 11 to 18. Perceptions of intergenerational stressors and coping strategies were examined for congruence by comparing adolescents' self-reports to parents' reports on their adolescents. Adolescents' reports on their parents were also compared to parents' reports on themselves. This study also specified family environment dynamics in relation to the study variables. Hypotheses that more congruent adolescent and parent perceptions about each other's stressors and coping were related to more cohesive family environments and more adaptive copings were generally supported. Family environment variables and congruent coping were related to psychological health symptoms as well. The findings contribute to current knowledge about the study variables examined in the context of the family.     

Adolescents' perceptions of the nature of their communication with parents

This study examines the effects of the age and sex of adolescent and the sex of parent upon adolescents' perceptions of the nature of their communication with each parent. Two hundred and ninety-six adolescents aged 13–17 years completed a communication schedule, rating 14 content areas along six process dimensions: frequency of conversation, initiator, levels of recognition of adolescents' opinion, self-disclosure, domination, and levels of satisfaction. Multivariate analyses of variance were conducted separately for each process dimension. Frequency ratings revealed that adolescent females of all ages reported talking more often with mothers than did adolescent males. Adolescent males, however, believed they talked more often than did females with fathers about interests, sexual issues, and general problems. Mothers were seen to initiate more conversations than fathers on a wide range of topics. Mothers were also perceived as more likely to recognize and accept the adolescents' opinions. Adolescent females believed they disclosed more to mothers than fathers, but males believed they disclosed equally to both parents. Males disclosed more to fathers than did females about their sexual or other problems, while females disclosed more often overall to their mothers than did males. Adolescent males were equally satisfied with their discussions with both parents, but females were more satisfied about conversations with mothers rather than fathers. In sum, the results suggest that mothers' more frequent initiation of discussions with their younger adolescents and their greater recognition of their opinions lead to older adolescents interacting more with mothers than fathers.Ph.D. in Social Psychology, University of Queensland.

Who's the Boss? Patterns of Perceived Control in Adolescents' Friendships

This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).     

Peer vs. parental influence in substance use among hispanic and Anglo children and adolescents

The relative influence of peer and parental influence on youths' use of alcohol and other drugs is explored among 446 Anglo and Hispanic youths, ages 9–17. Current users and abstainers are similar in age and gender. Among both groups, parental influence is more profound than that of peers. However, substance users, compared to abstainers, are more influenced by peers. Level of marijuana use by youths' friends is the most reliable predictor of drug use. Youths having viable relationships with parents are less involved with drugs and less influenced by drug-oriented peers.Funded by a grant (A-003-2) from the California Department of Alcohol and Drug Programs, R.

Protective Families in High- and Low-risk Environments: Implications for Adolescent Substance Use

This study used data from a sample of 6th to 12th grade students (N = 48,641, 51% female), nested in 192 schools, to determine if the influence of family-based protective factors varied across different school contexts. Hierarchical logistic regression models were used to examine the effects of individual-level family protective factors, relative to school-level aggregates of the same factors, on recent (past 30 days) use of cigarettes, alcohol, and marijuana. Cross-level interactions indicated that the effect of the student’s level of family protection, relative to other students in their school, differed depending on the aggregated school level of family protection. The results suggested that the benefit of belonging to a well-functioning family was more influential for students attending schools characterized by higher-than-average aggregated levels of protection compared to students attending schools of lower-than-average protection. Thus, family-level factors offered less protection for students in relatively high-risk school contexts. These results were consistent with a protective–reactive interaction and suggest that a thorough understanding of adolescent substance use must consider the complex interplay among adolescents, their families, and their social environments.     

Substance use by hispanic and white non-hispanic pregnant adolescents: A preliminary survey

White non-Hispanic and Hispanic adolescents aged 17 years and under n= 81) who delivered in San Jose, California area hospitals during a 6-week period were interviewed within 24 hours concerning their use of cigarettes, marijuana, and alcohol during pregnancy, and a number of background, social support, and psychosocial factors. Before 12–16 weeks of pregnancy, each of the substances studied was used by over 50% of this population, with 53% smoking cigarettes, 51% smoking marijuana, and 58% consuming beer or wine. Most substance use ceased after 12–16 weeks of pregnancy. There were no significant differences between ethnic groups in substance use. Multiple regression analyses showed that cigarette smoking decreased when social support was provided by the adolescent's partner and it was higher if parents smoked and/or used alcohol p<.001. Parental substance use, combined with lack of social support, was also associated significantly with marijuana use p<.001, explaining 30% of the variance. Use of birth control prior to pregnancy was related to beer and wine consumption p<.05, explaining 16% of the variance. Active inclusion of members of the adolescent's support network in pregnancy care, and initiative by educators and clinicians in discussing substance use, may accelerate its cessation. Ethnicityrelated behavior change strategies may be of little relevance to adolescent substance use during pregnancy.This study was funded by grant no.

Adolescent attachment to parents and friends in relation to aspects of self-esteem

This study explored the relative influence of adolescents' perceptions of their attachment relationships with their mothers, fathers, and friends on three measures of self-esteem. The sample consisted of 493 New Zealand adolescents ranging from 13 to 19 years of age. Two dimensions of the attachment relationship were assessed: the utilization of emotional support and proximity, and the quality of affect. The major findings were as follows: utilization of emotional support and proximity from mothers, fathers, and friends was minimally related to overall self-esteem, coping abilities, and social competence. The quality of affect toward mothers and fathers was significantly related only to social competence. These findings suggest that adolescent self-esteem is more strongly associated with the quality of affect toward parents and friends than with the utilization of these target figures for support or proximity. The notion that parents and friends may contribute to different facets of self-esteem is discussed.This research is based on the first author's doctoral dissertation at the University of Auckland.Received Ph.D. from the University of Auckland, Auckland, New Zealand.

Are Family Meals as Good for Youth as We Think They Are? A Review of the Literature on Family Meals as They Pertain to Adolescent Risk Prevention

Regular family meals have been shown to reduce adolescents’ engagement in various risk behaviors. In this article, we comprehensively examine the literature to review the association between family meals and eight adolescent risk outcomes: alcohol, tobacco, marijuana and other drugs; aggressive and/or violent behaviors; poor school performance; sexual behavior; mental health problems; and disordered eating patterns. The majority of the studies reviewed found associations in the relationship between family meals and adolescents’ risk profiles. More specifically, studies reporting significant associations found that adolescents who frequently ate meals with their family and/or parents were less likely to engage in risk behaviors when compared to peers who never or rarely ate meals with their families. Additionally, the influence of family meal frequency on youth risk outcomes appears to be dependent on gender, with family meals being a protective factor for females and males differently, depending on the outcome examined. However, the studies available about family meals and adolescent risk only examined the effect of family meal frequency, and not other components of family meals that contribute to the protective effect, and, thus, hinder the understanding of the mechanisms unique to family meals’ protective characteristics. Regardless of these limitations, the studies examined indicate that family meals may be protective and, therefore, have practical implications for parents, clinicians, and organizations looking to reduce adolescent risk behaviors. However, further examination is needed to better understand the mechanisms that contribute to the protective effect afforded by family meal frequency on adolescents.     

Attachment,individuation, and risk of suicide in late adolescence

Security of attachment and level of individuation from parents and peers was examined among 126 undergraduates, 42 with a history of suicidality, 42 who were currently depressed with no history of suicidality, and 42 normal controls. Suicidality was defined as history of serious suicidal ideation or suicide attempt. As predicted, students with a history of suicidality exhibited both the lowest security of attachment as well as the least degree of individuation in their current relationships with parents. In contrast, they were similar to depressed and control students on security of peer attachment and level of individuation from peers. Students with a history of suicidality rated their parents and mother as emotionally absent in childhood to a significantly higher degree than depressed and normal controls. This effect was independent of depression but not from gender. History of suicidality is more strongly associated with family instability than with parental divorce. Absence of parents as emotionally available attachment figures at a time when such availability is critical heightens adolescents' vulnerability to suicide.This research is based on the author's doctoral dissertation in clinical psychology, Boston University. The author was previously Clinical Fellow in Psychology, Beth Israel Hospital, Harvard Medical School.Major interests include attachment, suicidality, and adolescent family relationships.     

Differentiating Peer Contexts and Risk for Adolescent Substance Use

The peer context is perhaps the most salient, robust predictor of an adolescent's substance use. However, in previous studies, the peer context is often poorly defined. The current study examined 3 models to understand how substance use within best friendships, peer cliques, and social crowds predicts adolescents' substance involvement. A sample of 377 high school juniors and seniors completed surveys assessing substance use and peer relationships. Results suggest that each of these 3 dimensions of the peer context uniquely predict adolescent substance use. Moreover, these peer contexts interacted in the prediction of adolescents' substance use such that adolescents who were more highly embedded in substance-using peer contexts showed greater risk for substance use whereas adolescents with substance-using best friends showed a reduced risk for substance use if they had other close friends who were less involved with substances.     

The Longitudinal Relationships Between Rural Adolescents’ Prosocial Behaviors and Young Adult Substance Use

While many adolescents and young adults experiment with substances (e.g., alcohol, cigarette smoking, marijuana), recent research suggests that rural youth and young adults may be more at risk for substance use than their urban counterparts. This study was designed to examine the longitudinal relationships between rural adolescents’ prosocial behaviors and substance use in young adulthood. Furthermore, we examined the potential mediating effects of adolescent substance use, academic investment, and delinquency. Rural youth (N = 531; 263 girls) were surveyed in grades 10–12 (Time 1; M age = 16.17; SD = .91) and again in early adulthood (Time 2). Measures of prosocial behaviors, substance use, academic investment, and deviant activities were assessed at Time 1. At Time 2, measures of marijuana use, cigarette smoking, and getting drunk were administered. Overall, the findings showed that rural adolescents who frequently exhibit prosocial behaviors are less likely to engage in substance use in young adulthood than those who exhibit relatively low levels of prosocial behaviors. These findings indicate that prosocial behaviors may have positive health consequences, establishing behavioral trajectories that lead to lower levels of risky health behaviors in adulthood in rural populations.     

Comparison of adolescents' perceptions and behaviors in single- and two-parent families

This study investigated the self-concepts, school achievement, occupational aspirations, vocational maturity, and perceptions of parents of children from two-parent and single-parent homes. The sample contained 559 children, 19% from single-parent homes. A multivariateF indicated children from two-parent homes had significantly higher school grades and occupational aspirations. There were also significant differences in children's perceptions of relationships with fathers, but not with mothers. It was argued that family structure has an impact on adolescents' perceptions and behaviors.Received his Ph.D. from the State University of New York at Buffalo.

Parental criticism and young adolescent self-disclosure: A cross-cultural study

Criticism by mothers and fathers, as well as young adolescents' perceptions of parental criticism and their self-disclosure to parents, was assessed for a sample of 80 families. Of these, 40 were resident in Australia (20 Anglo-Australian and 20 Greek-Australian) and 40 were resident in Greece (20 professional and 20 working-class). There were no differences between the groups in amount of criticism by parents nor in adolescents' perceptions of criticism. Greek- and Anglo-Australian adolescents disclosed significantly less to parents than did the Greek adolescents. For Greek-Australian adolescents there was an inverse relationship between self-disclosure on a number of topics and perceived levels of parental criticism. The results were interpreted in terms of cultural differences between the groups and adaptive behaviors of the Greek-Australian adolescents.This research was supported by a University of Melbourne grant to the first author.Received Ph.D. from University of Melbourne.

Parent–Child Relations and Adolescent Self-Image Following Divorce: A 10 Year Study

This Australian study explored the links between self-image, family structure (divorced or intact), parent–child relations, and gender at 3 intervals over 10 years during adolescence (mean ages 14.7 at Time 1, 17.9 at Time 2) to early adulthood (mean age 24.9 at Time 3). The sample comprised 37 families at the point of divorce when interviewed in 1981–82, and 41 intact families of similar age, gender, and socioeconomic background. Initial measures of self-image (Offer Self-Image Questionnaire: OSIQ) and parent–child relations (Parent Bonding Inventory: PBI) were repeated in 1985 and 1990–91. ANOVAs showed that divorced fathers were perceived as significantly less caring than those from intact families at each interval. There were no family group differences on the control scale, nor on either scale for mothers. Correlations between PBI scales and OSIQ were significant for the sample as a whole, but were stronger for those from intact than divorced families. ANOVAs showed that when mothers' and fathers' parenting styles were seen as highly caring and also not over controlling (i.e., optimal), adolescent self-image was significantly better, irrespective of gender or family structure. Examination of the joint influence of both parents showed that at Times 1 and 2 adolescent self-image was significantly better when one or both parents, compared with neither, were optimal. At Time 3, this comparison was significant only when both parents were optimal. Self-image was related to whether or not a custodial parent was seen as optimal but not to the gender of the child or custodial parent.     

A cross-cultural comparison of sociopsychological factors in alcohol use among adolescents in Israel,France, and the United States

The correlates of alcohol use by adolescents are compared in three cultures with different prevalences of alcohol use: France, with high prevalence; Israel, with low prevalence; and the United States, in the middle. In all three countries, significant others, parents and peers, are more powerful predictors of alcohol use than are the adolescent's personal attributes, such as attitudes, behaviors, and demographic characteristics. Cross-cultural differences appear in the relative importance of parents and peers and in the structure of influence of parents and peers as role models. Parents are more important role models in Israel than in the other two cultures, while peers are more important in the United States than in France or in Israel.This research was partially supported by Research Grants DA01902, DA00064, and Research Scientist Grant K05-DA00081 from the National Institute on Drug Abuse, and by the Center for SocioCultural Research on Drug Use, Columbia University.Received Ph.D. from Stanford University.

Longitudinal Bi-directional Relationships Between Sleep and Youth Substance Use

Despite the known deficits in sleep that occur during adolescence and the high prevalence of substance use behaviors among this group, relatively little research has explored how sleep and substance use may be causally related. The purpose of this study was to explore the longitudinal bi-directional relationships between sleep duration, sleep patterns and youth substance use behaviors. Participants included 704 mostly white (86.4?%) youth, 51?% female, with a baseline mean age of 14.7?years. Self-reported substance use behaviors included past month alcohol, cigarette, and marijuana use. Sleep measures included sleep duration on weekends and weekdays, total sleep, weekend oversleep, and weekend sleep delay. Cross-lagged structural equation models, accounting for clustering at the school level, were run to determine the longitudinal association between sleep and substance use adjusting for socio-demographic characteristics, pubertal status, body mass index z-score, and depressive symptoms. Cigarette use and weekend sleep were bi-directionally related as were marijuana use and total sleep. No other bi-directional associations were identified. However, alcohol use predicted shorter weekend oversleep and marijuana use predicted increased weekend sleep and weekend oversleep. Sleep patterns and duration also predicted adolescents' cigarette, alcohol, and marijuana use. Sleep, both patterns and duration, and substance use among youth are intertwined. Future research is needed to explore these bi-directional relationships, as well as other important contextual factors that may moderate these associations.     

Psychosocial differences between occasional and regular adolescent users of Marijuana and Heroin

Data on marijuana and heroin use were obtained from 969 adolescents in Hong Kong, part of them being offenders. Very high drug use prevalence rates were found, which is due to the unique population studied. All but two of the heroin users were incarcerated youth. Drug use frequencies were highly associated with psychosocial variables such as sensation seeking, peer drug use, family drug use, susceptibility to peer pressure, perceived control to gain access to drugs, intention to try other substances, and perceived adverse consequences of drug use. Interactions were found indicating, for example, that regularly marijuana using girls and occasionally heroin using girls were characterized by higher levels of sensation seeking and susceptibility to peer pressure than their male counterparts. Polysubstance use was generally related to high levels of psychosocial vulnerability factors. The exclusive use of marijuana was associated with high susceptibility to peer pressure and with perceived control to gain access to drugs. The findings reflect a complex interplay of psychosocial variables with substance use in adolescents that, however, cannot be generalized beyond this particular sample in Hong Kong.Received Ph.D. in Clinical Psychology from the University of North Texas.

Coping styles of learning disabled adolescents and their parents

The study compares coping styles of 50 learning disabled and nonlearning dis-abled adolescents and their parents. Analyses indicate that learning disabled adolescents show less ability to appraise a source of stress and seek information in the various domains with which they are expected to cope. Also, they reveal a higher level of pessimism about problems in academic-related domains. Coping patterns of parents of learning disabled adolescents do not show clear differences from parents of nonlearning disabled. Yet mothers of learning disabled adolescents tend more to seek and accept help. Learning disabled adolescents' coping is clearly related to coping or more specifically to difficulties in coping of their parents. Results are discussed in the context of the special difficulties of the learning disabled during adolescence and the role their parents play during this developmental stage.Received Ph.
