This book explains the rationale for changes in the DSM-5® related to incorporating behavioral addictions alongside substance use disorders; it also illuminates the significance of including the construct of behavioral addictions in this widely used psychiatric diagnostic manual. The chapters herien describe eight behaviors often considered addictions, including gambling disorder, internet gaming disorder, internet addiction, food addiction, hypersexuality, shopping addiction, exercise addiction, and tanning addiction. Also examined are prevalence rates in epidemiological samples, risk factors, and promising treatment approaches. The result is an easy-to-use resource and guide for clinicians, students, and researchers.

"Contingency Management has been identified as the most efficacious intervention for substance use disorders. Despite the evidence of its efficacy in numerous clinical trials, contingency management is poorly understood and rarely utilized in practice settings, as no book exists specifically for clinicians. Contingency Management for Substance Abuse Treatment fills this gap as a clinician-oriented text that focuses on contingency management protocol development and implementation, and provides everything clinicians require to successfully apply a novel treatment in practice"--Provided by publisher.

Polydrug abuse is common among substance abusers, but few empirical or theoretical methods accurately characterize this phenomenon. This chapter describes a simulation paradigm that was developed to apply a behavioral economic analysis to understanding polydrug abuse. Heroin abusers 'purchased' drugs as the price of drugs or income varied. In Experiment 1, heroin price rose while prices of other drugs and income remained constant. Heroin purchases significantly decreased as heroin prices increased. As price of heroin rose, valium and cocaine purchases increased and cross-price elasticity coefficients indicated these drugs substituted for heroin. In Experiment 2, prices of both heroin and valium increased separately to determine symmetry of the substitution effect. While valium substituted for heroin, heroin purchases were independent of valium prices. Marijuana and alcohol purchases were independent of valium price, but both these drugs were weak substitutes for heroin. In Experiment 3, income rose while prices remained constant. At some changes in income, demand for heroin and cocaine was income elastic, with purchases rising in greater proportion than income. Marijuana, alcohol, and valium purchases did not vary significantly as a function of income. Choices in this simulation were reliable both between and within subjects. Moreover, drug choices in the simulation were correlated with drug use as determined by urinanalysis testing. These results are discussed in terms of the utility of a behavioral economics approach for characterizing polydrug abuse.
