This study presents the first psychometric data on the Changes in Sexual Functioning Questionnaire Short-Form (CSFQ-14), a self-report instrument to assess sexual functioning, in a sample of 104 males with drug abuse history. They were collected in 2008. The questionnaire was completed along with the Addictive Behavior Questionnaire and the Brief Sexual Function Inventory. A three-dimensional factor structure was observed in the CSFQ-14: Desire (alpha = .73), Arousal-orgasm (alpha = .67) and Pleasure (including only one item). Scores indicated adequate validity, with similar values to samples of depressive patients and lower values than the normal population.
