Adolescence can be a period of increased problem behavior, and parents often report this stage of development as being one of increased conflict with high levels of parenting-related stress and lower levels of confidence in parenting abilities. As a result, parents of adolescents seek out parenting information and support much more often than do parents of younger children. However, most parent training programs have been developed for parents of children aged 12 and under; very little is known about the use of parent training programs for parents of adolescents. Therefore, the purpose of this article was to examine the use of a behavioral parent training program for a population of parents with adolescent-aged youth to identify the characteristics of participants and examine pre-post changes. On average, both the parents and their youth had a high number of risk factors (e.g., substance abuse, domestic violence, clinical levels of problem behavior) when the program began. Significant changes were observed across both youth behavior and parent stress. Implications and directions for future research are discussed. (Contains 4 tables.)
