The treatment of coexisting chemical dependency and psychiatric disorders has long been a serious challenge for care providers. With the advent of managed care, counselors, case managers, and other professionals increasingly are called upon to treat very ill and troubled clients in outpatient settings. This popular volume offers a thorough introduction to clinical work with this difficult-to-treat population. Providing a unique synthesis of chemical dependency and mental health models, the book articulates a framework for assessment and treatment and describes a range of effective counseling and motivational strategies for adolescents and adults. The practical utility of the volume is enhanced by numerous clinical vignettes and clearly presented tables to aid in assessment. Appendices feature helpful reproducible forms.
