Antecedents of relapse and recent substance use.

The present study investigated determinants of relapse and antecedents of recent use for 30 substance abusers re-entering inpatient treatment. A structured interview assessment revealed that the patients relapsed within two months following previous treatment, yet waited 2.7 years before re-entering treatment. Alcohol was often the initial and subsequently the most frequently used substance. Determinants of relapse were a variety of interpersonal and intrapersonal events. However, antecedents to recent use were almost exclusively negative emotional states such as depression and loneliness. Implications for treatment are presented.
