To investigate change in personality disorder (PD) traits between early adolescence and early adulthood among individuals in the community.PD traits were assessed in 1983 (mean age = 14), 1985-86 (mean age = 16) and 1992 (mean age = 22) in a representative community sample of 816 youths.Overall, PD traits declined 28% during both adolescence and early adulthood. PD traits were moderately stable during the first 2-year interval, and were as stable as they have been reported to be among adults over similar intervals. PD trait stability declined slightly as the inter-assessment interval increased. Adolescents with PDs tended to have elevated PD traits during early adulthood.PD traits tend to decline steadily in prevalence during adolescence and early adulthood. However, adolescents with PDs often have elevated PD traits as young adults, and the stability of PD traits appears to be similar during adolescence and early adulthood.

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.

The authors examined the influences of domains of psychosocial risk and protective factors on male-partner condom use in a cobort of 209 female HIV-positive (HIV+) and HIV-negative (HIV-) injection drug users (IDUs) by use of a cross-sectional, retrospective design. Information collected from a structured questionnaire included data on psychosocial risk and protective factors in the personality, family, and peer domains; HIV status; and condom use. Among HIV+ IDUs, personality risk factors (e.g., unconventionality), family (e.g., low maternal identification), and peer factors were related to less male-partner condom use. Resources and condom availability were associated with greater male condom use with both HIV+ and HIV- IDUs. The psychosocial domains affected male condom use with both HIV+ and HIV- female IDU patients via two different mediational models. The findings suggest the need to use specific psychosocial interventions for risky sexual behavior among HIV+ and HIV- female IDUs.

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 authors studied the influences of domains of psychosocial risk factors on needle-sharing with familiar people and with strangers in a cohort of female injecting drug users (IDUs). Subjects were 119 female IDUs, 46% of whom were HIV+. Subjects were given individually administered questionnaire interviews: Using Pearson correlation coefficients and multiple hierarchical regression analyses, the authors found that personality, family, and peer attributes related to needle-sharing in women were similar to those found in men, with certain exceptions. The role of the family, particularly the Significant Other, was more important and proximal in its effect on needle-sharing behavior in women than in men. There was a main effect as well as a mediating effect of family in women, buffering risk factors leading to needle-sharing.

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.

We studied the psychosocial risk factors associated with Black, Hispanic, and White (N = 257) male intravenous drug abusers' needle-sharing behavior with familiar individuals and with strangers. Approximately half the subjects were HIV+. The findings supported a mediational model in that risk factors in the family domain were associated with peer and personality risk factors conducive to needle sharing that, in turn, were related to needle-sharing behavior.

This study was designed to examine the paternal determinants of male adolescent marijuana use in the context of the mother-son and parental relationships. In addition, parental factors affecting experimental vs regular use of marijuana were examined. Two hundred forty-six male college students and their fathers were administered written questionnaires. Results indicated that the father's personality attributes and socialization techniques are associated with the son's use of marijuana despite control on the mother-son relationship. Fathers of marijuana users score higher on measures of psychopathology and unconventionality, and are less likely to have established close relationships with their sons. In addition, marijuana users more than nonusers have unaffectionate mothers and parents with less harmonious marital relations. Also of importance were interactions within the family system. The significance of these second-order effects highlights the importance of examining the father-son relation in the context of mother-son and parental interactions.
