Purpose: Assess criminal attitudes.
Description: The PID is a self-report instrument that measures an individual’s degree of comfort (pride vs. shame) for engaging in certain criminal behaviors. The instrument consists of 10 different behaviors with each being scored using a 21-point scale ranging from -10 through 0 to +10 with negative numbers indicative of shame in engaging in the behavior and a positive number indicating pride in engaging in the behavior. Scores from each item are summed and then added to a constant of 100 such that all total scores are positive. Higher scores reflect greater criminal attitudes.
Psychometric Information: Normative data on the PID are available among adult inmates and probationers, juvenile offenders and college students. Internal consistency (i.e., Cronbach Alpha) estimates for the instrument range between .75 and .84. Examinations of the validity of the PID has found scores on the significantly discriminate between recidivists and non-recidivists and between those offenders with and without institutional behavior problems.
Applications: The PID can be used either for case classification contexts (e.g., intake, exit, or one-time assessments) and as a measure of treatment performance (e.g., pre-treatment and post-treatment comparisons).
