Alcohol and substance abuse in the adolescent population is a major health concern with a number of harms known to be associated with high levels of use. Few studies report on long-term health status of youth who have received treatment for a substance abuse problem during adolescence. This study aimed to describe the long-term status of a cohort of adolescents who received treatment in an intensive day treatment program situated in a tertiary care paediatric hospital. Youth participated in an interview that collected data using both standardized screening tools (GAIN-SS, AUDIT, CUDIT, DUI) as well as closed and open ended questions about education, employment, and physical and mental health status. Young adults in this sample continue to use alcohol and cannabis, with a proportion reporting problematic use. Their academic achievement is close to expected for their age group. They report concurrent mental health disorders; and as a cohort, access the health care system for both acute and chronic health conditions more than their contemporaries. These findings support the inclusion of academic, mental health and medical components in programs for adolescents with substance abuse, in order to address a broad range of determinants of health outcomes.  相似文献

ABSTRACT

This study aimed to identify predictors of learning and adherence to a previously validated compensatory calendar and note-taking system (Memory Support System; MSS) in persons with amnestic mild cognitive impairment (aMCI). Age, education, global cognition, depression, and memory-related self-efficacy were studied as predictors of individuals’ ability to learn the use of the MSS during the two-week training and of their adherence to the MSS 6, 12, and 18 months after training. How well an individual was able to learn the use of the MSS was itself examined as a predictor of adherence. Two-hundred-and-fifteen older adults with aMCI and their study partners (e.g., spouse, adult child) received MSS training one-hour daily for 10 days. Ordinal logistic regression analyses indicated that (1) global cognition predicted MSS learning at end of training, and (2) MSS learning at end of trainng predicted MSS adherence at 6, 12, and 18 months post-training. The current study suggests that offering compensatory strategies as early as possible for those with MCI might be of most benefit, and might have implications for long-term adherence.  相似文献
