Young adult gambling behaviors and their relationship with the persistence of ADHD.

Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD. This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults (n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent ADHD.

Pathways of youth gambling problem severity.

Prospective studies are needed to advance knowledge of the developmental features of gambling involvement and associated problems. Developmental pathways of youth gambling problem severity (no problem gambling, at-risk gambling, and problem gambling) are described on the basis of a 3-wave data set that spans midadolescence to young adulthood (N=305). The most prevalent group was the resistors (no problem gambling at all data points); 60% of study participants were in this group. New incidence cases (no problem gambling followed by at-risk or problem gambling) and desistors (at-risk or problem gambling followed by no problem gambling) were found among 21% and 13% of participants, respectively. Only 4% of cases were persistors, that is, at-risk or problem gambling at all 3 data waves. Findings are discussed in light of extant research on adolescent gambling that heretofore has not benefited from a developmental pathway perspective.

A prospective study of youth gambling behaviors.

Little is known about the course and outcomes of adolescent gambling. This prospective study describes findings from a 3-wave (Time 1 [T1], Time 2 [T2], and Time 3 [T3]) assessment of gambling behaviors among youth (N = 305). Stable rates of any gambling and regular gambling (weekly or daily) were observed across T1, T2, and T3. The rate of at-risk gambling significantly increased at T3 (young adulthood), whereas the rate of problem gambling remained stable over time. Several adolescent risk factors were associated with either T3 at-risk or problem gambling, many of which are risk factors for adolescent substance abuse. Findings suggest that important to the origins of young adult gambling problems are risk factors associated with the problem behavior syndrome of adolescence.

Measuring adolescent drug abuse and psychosocial factors in four ethnic groups of drug-abusing boys.

There is an absence of empirical work on the measurement of adolescent drug abuse among non-White ethnic youths. The field would benefit from psychometrically sound measures for ethnic groups. The psychometric properties of a multi-scale assessment tool for adolescent drug abuse, the Personal Experience Inventory (PEI), have been examined largely in White samples. The current study reports reliability and validity data for the PEI across four samples of boys (White, African American, Native American, and Hispanic). The results provide general psychometric support for the non-White groups. The use and limitations of the PEI in different ethnic/racial groups are discussed.

Internalizing and externalizing behaviors and their association with the treatment of adolescents with substance use disorder.

Whereas the treatment outcome research literature for adolescent alcohol and other drug abuse has shown recent advances (R. J. Williams, S. Y. Chang, & Addiction Centre Adolescent Research Group, 2000), significant knowledge gaps remain. A. E. Kazdin (2001) recently observed that one of the key questions for the field is to identify if client characteristics meaningfully mediate or moderate treatment outcome. There is support from the adolescent clinical literature that internalizing and externalizing personality subtypes are related to the onset and course of youth substance use disorders (D. B. Clark & O. G. Bukstein, 1998). The study extends this literature by examining the association of drug use behaviors outcome and subtyped adolescents (internalizers and externalizers; n = 141) who sought treatment at a 12-Step program. The analysis also includes a community-based control group (n = 94). Specifically, we examined the association of subtype and treatment retention and short-term (Year 1) and long-term (Year 4 and Year 5.5) drug involvement outcomes. Externalizers consistently showed poorer outcomes, including poorer treatment retention and greater drug use and drug disorder symptoms at each follow-up point. The treatment implications of the study are discussed.

Interplay of psychosocial factors and the long-term course of adolescents with a substance use disorder.

This paper examines the association of psychosocial factors and long-term drug use behaviors (year-5.5) among adolescents with a substance dependence disorder. One group received treatment with a 12-Step approach (n = 159) and one group was on a waiting list (n = 62). Four psychosocial factors (deviant behavior, peer drug environment, psychological disturbance and family estrangement), as measured by a standardized self-report questionnaire, were examined as predictors across three time points (year-1, year-4 and year-5.5). Improved outcome across time was significantly associated with decreases in deviant behavior, peer drug environment and family estrangement. However, psychological disturbance was not associated with outcome. Also, we did not find an effect on outcome as a function of age, gender and race. Youth that received treatment, as opposed to the waiting list youth, generally revealed a more favorable outcome across time. Treatment implications of the study findings are discussed.
