Standardized responses of the drug-related locus of control scale (DR-LOC) in drug-dependent individuals, who are currently enrolled in treatment, and non-dependent individuals from the community. The non-dependent group was subdivided into those individuals who have professional contact with drug-dependent individuals (health professionals) and those who have no such professional contact. These 3 groups differ significantly in their beliefs where the control over the decision to take drugs is located, in the individual such as cravings [internal locus of control (LOC)] or in environmental circumstances such as peer pressure (external LOC). The groups also differed significantly on control beliefs regarding the recovery from addiction. Individuals who have an internal sense of control believe a successful recovery from addiction is determined by a person’s own efforts to stay abstinent (internal LOC), whereas those with an external sense of control hold the view that a successful recovery from addiction is controlled by external factors such as treatment or support from friends and family.
