The Shorter PROMIS Questionnaire (SPQ)

Further validation of a tool for simultaneous assessment of multiple addictive behaviours

 

Abstract

There is both a theoretical and clinical need to develop a questionnaire which assesses a range of addictive behaviours. The Shorter PROMIS Questionnaire (SPQ) is a 16 scale self-report instrument assessing the use of nicotine, recreational drugs, prescription drugs, gambling, sex, caffeine, food bingeing, food starving, exercise, shopping, work, relationships dominant and submissive, and compulsive helping dominant and submissive. Clinical cut-off scores using the 90th percentile were derived from a normative group of 508 individuals. These cut-offs correctly identified 78% to 100% of cases within clinical criterion groups of specific disorders. The clinical sample also completed other validated scales assessing gambling, eating, alcohol and drug use; correlations were typically .7 with relevant SPQ scales. The SPQ food, drug and alcohol scales were at least equivalent to validated comparison scales in the strength of their relationship to relevant clinical criterion groups. Internal consistency was high for all scales, and retest reliability was generally good. This clinically useful instrument provides a broad assessment of addictive problems, thereby benefiting both the treatment provider and the client.
