This study examined the relationship between the domains of environmental factors, family illegal drug use, parental child-rearing practices, maternal and adolescent personality attributes, and adolescent illegal drug use. A nonclinical sample of 2,837 Colombian youths and their mothers were interviewed about intrapersonal, interpersonal, and environmental factors in their lives. Results indicated that certain environmental factors (e.g., violence, drug availability, and machismo), family drug use, a distant parent-child relationship, and unconventional behavior are risk factors for adolescent illegal drug use. As hypothesized, results showed that the adverse effects of family illegal drug use on adolescent drug use can be buffered by protective parental child-rearing practices and environmental factors, leading to less adolescent illegal drug use. Prevention and treatment efforts should incorporate protective environmental, familial, and intrapersonal components in order to reduce adolescent illegal drug use.

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.

Young adult drug use stemming from childhood aggression, the parent-child mutual attachment relationship, and the effect of unconventionality were studied. Youngsters and their mothers were interviewed when the former were early adolescents, late adolescents, and young adults. Additional data were collected from the mothers when their youngsters were children. The analysis was conducted on youngsters who had complete data at all 4 points in time. The findings were in accord with the family interactional model; that is, the parent-child mutual attachment relationship affects unconventionality in the youngster, which, in turn, affects young adult drug use. The results indicate that the parent-child mutual attachment relationship does so through (a) the stability of the attachment relationship from childhood to young adulthood, (b) the stability of unconventional personality and behavioral attributes from early adolescence to young adulthood, and (c) the stability of drug use from early adolescence to young adulthood. The findings imply that (a) early intervention with respect to aggression, (b) interventions that focus on strengthening the parent-child bond and conventional behavior, and (c) interventions aimed at early drug use should be most effective in reducing young adult drug use.

To examine the interrelationship of acculturation, family, personality, ecology, and peer domains measured in adolescence as they impact drug use 5 years later and to assess the role of family variables as buffers against personality risks.Youths completed questionnaires in classrooms at T1 and were individually interviewed at T2 (mean age = 20 years). Data were analyzed separately for African-Americans and Puerto Ricans using correlations, hierarchical multiple regressions, and two-way interactions.Most results were similar for both ethnic groups. Eighty percent of the T1 variables significantly related to T2 stage of drug use. A mediational model of the path to drug use was supported. Acculturative influences were associated with family relations, which in turn were related to personality attributes. A reciprocal relationship emerged between the personality and peer domains in their impact on drug use. Family variables primarily enhanced the effect of protective personality traits on drug use.Stability of drug use alone cannot explain the relationship between the earlier domains and later drug use. Specific adolescent risks have long-lasting effects. The personality domain has a direct effect on later drug use despite a benign picture in the acculturation, family, and peer domains.

The goals of this longitudinal, prospective study were to 1) examine coping strategies of HIV-positive (HIV+) and HIV-negative (HIV-) injecting drug users; 2) study the relationship of earlier social support to later coping in HIV+ men; and 3) examine the effects of earlier coping strategies on later psychosocial function. The authors studied 287 men given a structured questionnaire at two points in time. HIV+ subjects scored higher than HIV- subjects on measures of AIDS-related adaptive coping (social support) and AIDS-related maladaptive coping (aggression), but not on general coping. General coping was not specifically AIDS-related, but was correlated positively with adaptive coping and negatively with maladaptive coping. These results suggest that earlier general coping is related to the later avoidance of maladaptive coping, and they have specific implications for teaching preventive strategies. AIDS-related adaptive or maladaptive coping techniques may be used simultaneously, and coping behavior may change over time. Earlier social support is related positively to aspects of later coping in HIV+ men.

How parental personality and drug use and the parent-child relationship are related to a toddler's anger and negativity was investigated. The sample consisted of 62 female and 53 male 2-year-old children and their parents. The results supported a mediational model. The father's drug use and parental personality attributes were linked to the child's anger and negativity indirectly, through the parent-child relationship. The findings indicated that maternal personality and child-rearing practices had a greater effect on the child than the paternal characteristics or the father-child relationship did. The results also suggested that the effect of one parent on the child was altered by the relationship the child had with the other parent. Implications for prevention and treatment are discussed.

Using a family interactional theoretical framework giving primacy to the mutual attachment between parent and child, we examined the interrelationship of acculturation, ecological factors, family, personality, peers, and drug context domains with drug use in an inner city sample. We also assessed the extent to which family protective factors mitigated against risks for drug use from most of the other domains. The sample consisted of 695 African-American and 637 Puerto Rican 7th-10th graders who answered the questionnaire while listening to it on personal tape players in their classrooms. The results of hierarchical regression analyses sufficiently supported the hypothesized sequence of interrelationships in both ethnic groups to substantiate our developmental model of drug use. We also found protective buffers common to both ethnic groups and buffers specific to each group. The implications of the results for targets and timing of intervention in the path to drug use are discussed.

Childhood and adolescent intrapersonal and interpersonal influences on older adolescents' drug use were examined with an interactional approach. Data were obtained when subjects were 5-10, 13-18, and 15-20 years old. Latent-variable confirmatory factor analysis was used to determine the fit of the variables to the latent constructs. Next, a structural model was hypothesized and tested to assess the influences of childhood and earlier adolescent factors on later adolescent drug use. Childhood aggression and parental sociopathy affected drug use in late adolescence. Unconventionality during early and middle adolescence had an important and pervasive impact on all aspects of middle and late adolescent functioning. Finally, both intrapersonal and interpersonal factors from childhood and early adolescence affected self-drug use during middle and late adolescence.

The interrelationship of neighborhood, school, peer, and family factors and adolescent drug involvement was investigated. Data were collected separately from 518 adolescents and their mothers when the children were between 9 and 18 years of age and again two years later. Neighborhood and school effects were not directly related to adolescent drug use. Neighborhood effects were mediated through the domains of school, peer, and family; school effects were mediated through the peer domain. Family and peer variables had a direct impact on adolescent drug involvement. Risk factors in the adolescents' peer environment can be ameliorated by protective factors in their school environment. Implications for the prevention of drug use are discussed.

This study examines the interactive effects of background factors and personality/attitudinal and perceived environmental dimensions on adolescent drug behavior. Data were collected during home interviews using a structured interview schedule. The sample consisted of 403 British West Indian black, American black, and white adolescents, ranging in age from 13 to 17. Results suggested that two processes, nonconformity to conventional middle class values at both the personality/attitudinal and institutional level, and modeling of familial and peer drug use account in large part for adolescent drug behavior. The majority of correlates of adolescent drug behavior were similar in different sex, age, and ethnic groups.

This study examined prenatal, perinatal, and early childhood risk factors in relation to the etiology of adolescent involvement in cigarettes, alcohol, marijuana, and other illicit drugs. Over a span of 10 years, data were collected on 638 mainly White mother-child pairs at three points in time: at T1, when the children were 1 to 10 years old; at T2, when they were 9 to 18, and again at T3, when they were 11 to 20. Results showed that the early risks of an unwanted pregnancy and major illness were linked to all of the drug categories except "other illicit drugs." Aspects of mutual attachment in the mother-adolescent relationship were negatively correlated with adolescent drug use. Data on the interrelationship of the domains (i.e., sets of variables) of early risk factors and mother-adolescent relations supported an independent model with respect to cigarette and marijuana involvement, a finding in keeping with results showing that early risk did not significantly affect mother-adolescent relations. However, mother-adolescent protective factors were able to mitigate the impact of early risk factors on adolescent drug involvement.
