Abstract

Purpose

To ascertain the prevalence of psychiatric symptoms and substance use disorders among adolescents with a lifetime history of foster care placement, using data from a nationally representative sample of U.S. adolescents.

Methods

We studied adolescents aged 12–17 years in the public use file of the 2000 National Household on Drug Abuse (n = 19,430, including 464 adolescents with history of foster care placement). Psychiatric symptoms and substance use disorders were ascertained through direct interviewing of adolescents. Logistic regression analyses were used to estimate the odds of past-year psychiatric symptoms and substance use disorders among adolescents involved with foster care, as compared to those without a lifetime history of foster care placement (comparison group).

Results

Adolescents involved with foster care had more past-year psychiatric symptoms, and especially more conduct symptoms, and past-year substance use disorders than those never placed in foster care. Adolescents involved with foster care were about four times more likely to have attempted suicide in the preceding 12 months (adjusted odds ratio [AOR] 3.95; 95% confidence interval [CI] 2.78, 5.61), and about five times more likely to receive a drug dependence diagnosis in the same period (AOR 4.81; 95% CI 3.22, 7.18).

Conclusions

Adolescents involved with foster care have a higher prevalence of psychiatric symptoms and drug use disorders than those never placed in foster care. Additionally, the results of this study suggest that they may be at elevated risk for suicide attempts.

Data source

This study is based on data from the public use file of the 2000 National Household on Drug Abuse (NHSDA) [20]. This study was declared exempt from the Research Triangle Institute (RTI) International institutional review board because it used an existing public use data file. No information or identifiers on the data file can be associated with any survey respondent. The annual NHSDA is designed to provide national estimates of the use of a variety of licit and illicit substances by Americans

Results

In this section, we refer to adolescents with a lifetime history of foster care placement as “FC adolescents” and to those without such a history as the comparison group.

Discussion

Adolescents involved with foster care had more psychiatric symptoms of every type assessed than adolescents in the comparison group. This finding concurs with the extant literature [1], [3], [5], [6], [27], [28]. Compared with adolescents never placed in foster care, the past-year prevalence of conduct and anxiety symptoms was higher among adolescents involved with foster care. The preponderance of conduct symptoms among foster children has been reported by numerous investigators in the U.S.
