Positive (but not negative) punishment predicts anxiety and depression among prostate cancer patients: An exploration of the behaviour analytic model of depression

The relative power of Positive and Negative Punishment as predictors of anxiety and depression was investigated within the gender-specific population of Prostate Cancer patients. As well as being a more powerful predictor of total test scores, Positive Punishment was also a stronger predictor of the presence of clinical levels of anxiety and depression. Examination of the particular Positive Punishment events that were significantly associated with clinical anxiety and depression showed considerable overlap, supporting the concept of a combined anxiety-depression disorder. Suggestions for behavioural interventions with this patient group are made.
