The Rotter I-E scale as a predictor of relapse in a population of compulsive gamblers.

Profile surveys, completed Rotter I-E scales, and questionnaires on past relapse behavior were collected from 108 New Jersey compulsive gamblers who attended Gamblers Anonymous, and an attempt was made, based on the findings, to predict incidence of compulsive gamblers' relapse. Relationships between I-E scores and extent of relapse-free periods, and I-E scores and relapse, with the variables of religious background, age, marital status, education, type of work, and childhood physical abuse were investigated. In every instance the relationship found was statistically non-significant.
