The issue of delinquency among truant youths is insufficiently documented in the literature. There is a need to elucidate this issue, and assess the efficacy of interventions to reduce this problem behavior. The present National Institute on Drug Abuse (NIDA)-funded study addressed this gap by examining the impact of a Brief Intervention (BI), originally designed to address youth substance use, on their delinquent behavior over an 18-month follow-up period (for self-reported delinquency) and a 24-month follow-up period (for official record delinquency). A number of significant BI intervention effects with sizable effect sizes were found, as well as a number of marginally significant BI effects. In particular, significant reductions in arrest charges at 24-month follow-up for youths receiving BI services compared to controls were among the key findings of this study. Service delivery implications and directions for future analyses are discussed.

Truant youths are likely to engage in a number of problem behaviors, including sexual risky behaviors. As part of a National Institute on Drug Abuse (NIDA)-funded, prospective intervention project, a sample of truant youths' sexual risk behavior was tracked over five time points. Analyses of the data was informed by four objectives: (a) determine if a growth model parameterization was consistent with the youths' sexual risk behavior, (b) assess the impact of a brief intervention (BI) targeting substance use on their sexual risk behavior over time, (c) identify any sexual risk behavior subgroups, and (d) identify any differential, longitudinal effects of the BI on the youths' sexual risk behavior. Results indicated the youths' sexual risk behavior reflected a linear growth model; no intervention effects were found on their sexual risk behavior over time; distinct sexual risk behavior subgroups were found; and no patterned intervention effects were found in regard to the sexual risk behavior subgroups. At the same time, there is a very serious need to provide effective sexual risk reduction intervention services to truant youths.

School truancy among teenagers remains a serious national problem, as evidenced by its significant association with school performance, psychological, and behavioral problems. Truancy is also positively associated with substance abuse. This study presents 18-month outcome data from a National Institute on Drug Abuse (NIDA)-funded controlled trial that examined the efficacy of a brief intervention (BI) to reduce marijuana use among truant youths. Adolescents and their parents were randomly assigned to receive either a two-session youth-only session (BI-Y), two-session youth and additional parent session (BI-YP), or standard truancy services (STS). Analyses of an auto-regressive lag model examined marijuana use at three months, six months, 12 months, and 18 months post-intervention. Results indicated adolescents receiving BI services, especially BI-Y services, showed significant reductions in marijuana use, at 18-month follow-up. BI-YP youths showed a greater increase in marijuana use than BI-Y youths. Reasons for this unexpected finding are discussed. Implications of the results for future research and service delivery also are discussed.

Few studies investigating the validity of marijuana use have used samples of truant youths. In the current study, self-reports of marijuana use are compared with urine test results for marijuana to identify marijuana underreporting among adolescents participating in a longitudinal brief intervention for drug-involved truant youths. It was hypothesized that marijuana underreporting would be associated with alcohol underreporting and engaging in sexual risk behaviors. The results indicated marijuana underreporting was significantly associated with self-denial of alcohol use, but not associated with sexual risk behavior. Also, there was an age effect in marijuana use underreporting such that younger truant youths were more likely to underreport marijuana use, compared to older truant youths. Implications for policy and future research are discussed.

Substance use and sexual risk behaviors are common among adolescents, but research has focused attention on alcohol use. Much less is known about the relationship of marijuana use and sexual risk behavior among high-risk, especially truant, youths. We report interim findings from a NIDA-funded experimental, brief intervention (BI) study involving truant youths and their parents/guardians. Longitudinal data were analyzed to study (1) the relationships between the youths' marijuana use and sexual risk behavior and (2) the effects of a substance use BI on their marijuana use and sexual risk behavior. A growth model analysis for parallel processes was conducted to study relationships between marijuana use and sexual risk behavior, and to assess the overall BI effect on linear and quadratic trends in subgroups of youth differing in their sexual risk behavior and marijuana use. Implications of the results for future research and service delivery are considered.

Truant youths frequently experience family problems, emotional/psychological issues, substance misuse, and delinquency. They are likely engaging in alcohol use and sexual risk behavior at a higher rate than the general youth population. Early intervention services would benefit them, their families, and society. We present interim findings from an ongoing, National Institute on Drug Abuse-funded, experimental, brief intervention (BI) study involving truant youths and their parent/guardians. Baseline, 3-, 6-, and 12-month follow-up data were analyzed to determine whether alcohol use and sexual risk behaviors were longitudinally related, to examine the effects of the BI on alcohol use and sexual risk behaviors, to identify subgroups of youths involved in alcohol use and sexual risk behaviors, and to assess the impact of the BI on these subgroups. Results indicated alcohol use and sexual risk were longitudinally related. Limited treatment effects were observed for alcohol use. Implications for future research and service delivery are considered.

The relationship between substance use, mental health disorders, and delinquency among youth is well documented. What has received far less attention from researchers is the relationship between these issues among truant youth, in spite of studies that document truants are a population at risk for negative outcomes. This study bridges this gap by (a) examining psychosocial functioning and delinquency among truants and (b) assessing the efficacy of a brief intervention (BI) in reducing delinquent behavior over time. To meet these objectives, data were collected from 183 truant youth enrolled in an ongoing National Institute on Drug Abuse (NIDA)--funded BI project. Informed by a developmental damage perspective, a structural equation model was formulated and estimated. Interim results provide overall support for the model and suggest that the BI may be a promising, innovative intervention for truant youth. Service delivery implications and directions for future analyses are discussed. (Contains 5 tables, 1 figure, and 1 note.)

Intervention Project. Results identified two classes of youths: Class 1(n=9) - youths with low levels of delinquency, mental health and substance abuse issues; and Class 2(n=37) - youths with high levels of these problems. Comparison of these two classes on their urine analysis test results and parent/guardian reports of traumatic events found significant (p less than 0.05) differences between them that were consistent with their problem group classification. Our results have important implications for research and practice. (Contains 1 note and 5 tables.)

Truant youths represent a critical group needing problem-oriented research and involvement in effective services. The limited number of studies on the psychosocial functioning of truant youths have focused on one or a few problem areas, rather than examining comorbid problem behaviors. The present study addresses the need to examine the interrelationships of multiple domains of psychosocial functioning, including substance involvement, mental health, and delinquency, among truant youths. Exploratory structural equation modeling on baseline data collected on 219 truant youths identified two major factors reflecting psychosocial functioning and found that the factor structure was similar across major sociodemographic subgroups. Further analyses supported the validity of the factor structure. The research and service delivery implications of the findings are discussed. (Contains 3 tables and 1 figure.)
