As someone who has been witnessed firsthand the emotional pain and suffering that addiction can afflict, Kassel (psychology/ director, Substance Abuse Research Laboratory, U. of Illinois at Chicago) collects 11 current theoretical and treatment perspectives on the abuse of legal and illegal drugs. Topics discussed by North American psychologist include re-formulations of negative and positive reinforcement models of drug addiction, and cognitive models of drug effects on emotion; recent studies on the psychobiology of mood-drug behavior associations; developmental factors; and advances in assessment and treatment including psychosocial models of addiction and relapse, and individual-level analysis.
