To evaluate the psychometric properties of an adaptation of the Alcohol and Alcohol Problems Perceptions Questionnaire to measure the attitudes of staff to working with drug users (the DDPPQ).
Postal survey: a questionnaire was mailed to participants on two occasions.
A large urban National Health Service (NHS) mental health service.
A stratified random sample of medical staff, clinical psychologists, occupational therapists and nurses (n = 672) who work within generic mental health, adolescent psychiatry, forensic psychiatry and alcohol and drug services. Response rate at Time 1 was 56% and 68% at Time 2.
A structured demographic questionnaire; individual item and total scores for the DDPPQ administered on two occasions 4 weeks apart; data relating to the content validity of the instrument.
A principal component analysis confirmed the DDPPQ's construct validity and participants confirmed its content validity. Following analysis of the instrument's test-retest reliability and its principal component structure it was reduced to a 20-item scale. Its five subscales related to role adequacy, role support, job satisfaction, role-specific self-esteem and role legitimacy.
The refined DDPPQ was shown to be a valid and reliable tool which can be used to measure attitudes of people in relation to working with drug users.
