This workbook was designed for use in conjunction with classroom instruction and the parent support group model. Its purpose is to help parents both prevent and effectively intervene in their children's unwanted behaviors, such as drug use and gang involvement. Based on the premise that children should be allowed to make choices and then be held accountable for those choices, the authors devised a sixteen-unit program which provides parents the techniques to improve their relationship with their children. Presented in two parts, Part One of the program lays the foundation for change. Topics in this section include strategies on understanding children, addressing problem behaviors -- with emphasis on adolescent drug use and youth gangs -- and developing personal action plans. Part Two discusses how to change behavior and improve the parent/child relationship. Offered are tips on parental support; understanding the dynamics of change; managing conflicts; active listening; communicating parent's views; building positive self concepts; being consistent; elaboration of expectations, standards, and values; and promoting family unity. The closing unit reviews the previous material and presents themes for parents to master. Included are handouts which can facilitate self-help support groups. (RJM)
