Researchers studying relapse for an addictive behavior have employed two different conceptual models. Researchers concerned with typologies of relapse situations have developed a variety of discrete classes of high risk situations. Researchers who have employed a Self-efficacy approach have typically assessed different situations but scored the measure as a single general construct. Using structural modeling, this paper evaluates five alternative measurement models, representing alternative conceptualizations. A hierarchical model which integrates the previously competing models provided the best fit to the data and serves to explain a large body of previous findings. The model includes three first order constructs (Positive/Social; Negative/Affective; and Habit/Addictive) and one general second-order factor. The results were replicated across two different response formats and two different subject samples.
