Psychometric evaluation of the marijuana and stimulant effect expectancy questionnaires for adolescents.

Alcohol expectancies are important in the mediation and prediction of alcohol use. Expectancies for the effects of other drugs, although less well delineated, appear equally important. Therefore, development and validation of expectancy measures for drugs other than alcohol is necessary for evaluating the importance of these constructs. We examined the factor structure, reliability, and validity of the Marijuana Effect Expectancy Questionnaire (MEEQ) and the Stimulant Effect Expectancy Questionnaire (SEEQ) in clinical and community samples of adolescents as they moved into young adulthood (N=279). Confirmatory factor analyses (CFAs) supported the a priori factors, and we found good reliability for most individual scales. Temporal stability and convergent and discriminant validity of drug effect expectancies were supported in this sample of adolescents and young adults. Drug effect expectancies were associated with drug preference and drug use patterns over 2 years. Use of these measures may aid our understanding of the etiology and course of marijuana and stimulant involvement during adolescence and young adulthood.

Prevalence of psychiatric disorders in youths across five sectors of care.

OBJECTIVE: To examine the prevalence of psychiatric disorders among youths from the following five public sectors of care: alcohol and drug services (AD), child welfare (CW), juvenile justice (JJ), mental health (MH), and public school services for youths with serious emotional disturbance (SED) in San Diego, California. METHOD: The Diagnostic Interview Schedule for Children was administered between October 1997 and January 1999 for 1,618 randomly selected youths aged 6-18 years who were active in at least one of the five sectors. RESULTS: Fifty-four percent of the participants met criteria for at least one study disorder. Attention-deficit/hyperactivity disorder (ADHD) and disruptive behavior disorders (50%) were much more common than anxiety (10%) or mood (7%) disorders. Youths who were active in the MH and SED sectors were more likely than those not in these sectors to meet criteria for a disorder; youths in the CW sector were least likely. CONCLUSIONS: Rates of psychiatric disorders, specifically ADHD and disruptive behavior disorders, are extremely high for youths in public sectors of care. Rates are generally higher in sectors designed to serve youths with psychiatric needs, but the prevalence of disorders was also high in sectors not specifically designed for this need (e.g., CW and JJ).

Prevalence of adolescent substance use disorders across five sectors of care.

OBJECTIVE: To examine the prevalence of substance use disorders (SUDs) among adolescents who received services in one or more of the following public sectors of care: alcohol and drug (AD), juvenile justice (JJ), mental health (MH), public school-based services for youths with serious emotional disturbance (SED), and child welfare (CW), in relation to age, gender, and service sector affiliation. METHODS: Participants included 1,036 adolescents aged 13 to 18 years, randomly sampled from all youths who were active in at least one of the above five sectors of care (N = 12,662) in San Diego County California. SUDs were assessed through structured diagnostic interviews conducted from October 1997 through January 1999. RESULTS: SUDs were found for youths in all sectors of care, with lifetime rates of 82.6% in AD, 62.1% in JJ, 40.8% in MH, 23.6% in SED, and 19.2% in CW. Rates of SUDs were significantly higher among older youths and males. Sector differences held even when accounting for the effects of age and gender. CONCLUSIONS: SUDs are highly prevalent among youths receiving care in the AD service sector as well as other sectors, particularly JJ and MH. These findings have implications for assessment, treatment, and service coordination for youths with SUDs in diverse sectors of public care.

Adolescent substance use and sexual risk-taking behavior.

PURPOSE: To examine the relationship of adolescent substance use and dependence to sexual risk-taking behavior in late adolescence and young adulthood. METHODS: We prospectively examined self-reported sexual behaviors and substance involvement questionnaires in a sample of youth in substance abuse treatment programs and a comparison sample of sociodemographically similar community youths without histories of substance use disorders recruited from media ads. Assessments of sexual behaviors and substance involvement (78% white, 51% female) were collected at 2, 4, and 6 years after initial assessments, as they transitioned from middle adolescence to young adulthood (from age 15.5 to age 21.5 years, on average). The two samples were compared using Chi-square, analysis of variance, and multivariate analysis of variance approaches. Continuous indicators of high-risk sexual behaviors and substance involvement were analyzed with multiple regression. RESULTS: Earlier age of onset to sexual activity, more sexual partners, less consistent use of condoms, more sexually transmitted diseases (STDs), and greater prevalence of human immunodeficiency virus testing were reported by youth in the clinical treatment sample relative to sociodemographically comparable nonabusing community youth. High rates of STDs were found among females, and more substance-abusing females reported pregnancies than community females. Substance involvement continued to be associated with high-risk sexual behavior throughout the transition into young adulthood. CONCLUSIONS: Youth identified with substance problems are more likely to engage in risky sexual behaviors during adolescence and to continue risky sexual behaviors to the extent that substance problems persist. Risk reduction education should be included with adolescent substance abuse treatment.

Assessment of intimate partner violence among high-risk postpartum mothers: concordance of clinical measures.

Intimate partner violence (IPV) may be a more common problem than some conditions for which pregnant women are routinely screened and evaluated. Screening for IPV necessitates competence in assessment using reliable and valid instruments. The present study examines the concordance in the prevalence of abuse reported by 436 high-risk postpartum mothers using (1) a single item hospital screen, (2) trained paraprofessional interviewer-interview format, and (3) the Conflict Tactics Scale (CTS), a standardized research instrument. The hospital screen identified 4% of the sample as scared, threatened or hurt, the Family Stress Checklist (FSC) identified 16.9% of the fathers as having severe potential for violence, and the CTS identified 18.6% of the sample as victims of physical abuse at the hands of the baby's father. There was minimal overlap between the ratings of severe potential for violence and the occurrence of violence as assessed by the CTS. Study findings illustrate the inadequacy of current procedures for detecting IPV with high-risk populations and highlight the need to develop reliable and valid assessments that can be easily utilized in the hospital setting.

Correlates of life stress in an alcohol treatment sample.

Men in alcohol dependence treatment commonly report elevated levels of stressful life experiences prior to entering treatment. Clinical researchers have argued that training patients to cope with stress is an important aspect of therapy for alcohol dependence. Current age and age of onset of alcohol dependence are two patient characteristics that may relate to stress and allow mental health care providers to anticipate patient needs more readily. This study examines whether current age and age of onset of alcohol dependence are related to the type of stress experienced preceding treatment. Participants were 350 male veterans receiving inpatient treatment for alcohol dependence who completed a semistructured interview-based life stress assessment. The likelihood of life events related to achievement, relationship, and legal problems decreased with age; the likelihood of health difficulties increased with age; and age and age of onset of alcohol dependence interacted to predict health difficulties. These results indicate that the nature of some stress experiences prior to treatment for alcohol dependence may be related to current age and the course of alcohol dependence.

Correlates of adolescents' satisfaction with mental health services.

While there has been increased attention to consumers' satisfaction with mental health services as an indicator of quality of care, little is known about the construct of consumer satisfaction, especially for youth. The goal of this study was to examine potential correlates of adolescents' satisfaction with mental health services. One hundred eighty adolescents who had received out-patient mental health services completed a multidimensional satisfaction scale and measures of behavior problems, attitudes and expectations about treatment, perceived choice/motivation in seeking treatment, and service use history. Results indicate that the strongest unique correlates of satisfaction are severity of behavior problems, positive expectations about services, and perceived choice in seeking services. Satisfaction with services was also associated with service site, length of time in treatment, and reason for entering treatment. Demographic variables were not related to satisfaction. A discussion of the appropriateness of using satisfaction as an indicator of quality of care is included.

Adolescent alcohol and drug abuse and health.

PURPOSE: To examine the relationship of adolescent alcohol and drug use over a 5-year period to cumulative health problems in late adolescence and young adulthood. METHODS: We prospectively examined self-reported health problems in a sample of adolescents, some of whom received treatment for substance use disorders and had consistently poor substance use outcomes (n = 38), some of whom received treatment for substance use disorders and had positive substance use outcomes (n = 30), and a low alcohol and drug use community comparison group (n = 48). Data regarding health-related problems of these adolescents (mean, 15.9 years; 83% Caucasian; 56.5% female) were collected at 2, 4, and 6 years following initial assessments. RESULTS: Alcohol and/or drug involvement severe enough to warrant treatment during adolescence was associated with more cumulative health problems and severe health problems for girls and more cumulative health problems for boys. Protracted and continuous abuse of alcohol and drugs was associated with more cumulative and severe health problems for girls and more severe health problems for boys. CONCLUSIONS: These results suggest that significant health problems and concerns are related to both brief and protracted alcohol and drug abuse during adolescence. Health problems will likely become even more evident as early-onset, chronic substance abusers continue to age.

Modeling of alcohol use mediates the effect of family history of alcoholism on adolescent alcohol expectancies.

The relative impact of biological family history of alcoholism and exposure to abusive parental drinking on alcohol effect expectancies of adolescent offspring were investigated in the present study. Exposure to familial models of alcohol abuse and biological family history were both predictive of positive alcohol effect expectancies of adolescent offspring. Degree of exposure to an alcohol-abusing family member mediated the relationship between biological family history of alcoholism and adolescent alcohol outcome expectancies. These results support prior findings of expectancy differences between youths with and without a family background of alcoholism and provide evidence supporting the significance of family modeling influences in the development of adolescents' alcohol expectancies.

Influences on adolescent substance dependence: conduct disorder, depression, attention deficit hyperactivity disorder, and gender.

OBJECTIVE: In adolescents, conduct disorder (CD), attention deficit hyperactivity disorder (ADHD), and depression are frequently comorbid with substance dependence (SD). We hypothesized that the prevalence and severity of CD, major depressive disorder (MDD), and ADHD would differ by gender, and that these conditions would associate differentially with severity of SD in males and females. METHODS: We examined these issues, using standardized diagnostic interviews, in 285 male and 82 female adolescents referred for comorbid CD and SD. RESULTS: Males and females did not differ significantly in severity of substance involvement, MDD, or ADHD, but males had more severe CD. MDD severity was the only variable significantly associated with SD severity for females, while for males, severity of CD combined with MDD and ADHD was significantly associated with SD severity. CONCLUSIONS: Among referred adolescents, CD, MDD, and ADHD may all be important concomitants of SD in males, while in females, depression may be the primary variable related to SD.
