title: Adaptation, equivalence, and validation of the changes in sexual functioning questionnaire-drugs in a sample of drug-dependent men.
abstract: This study aimed to adapt and validate the changes in sexual functioning questionnaire-short form in a sample of drug-dependent men, achieving equivalence. Participants were 301 drug-dependent and 202 non-drug-dependent men took part in this study. The analysis of invariance revealed strong factor equivalence (RMSEA = .06; χ2/df = 2.66 and ΔCFI = -.01) for the 4-factor model (desire, pleasure, arousal, and orgasm). This model has shown the best fit indices. No items showed differential item functioning (ΔR (2) Nagelkerke < .035). Reliability ranged from α = 0.83 for pleasure to α = 0.61 for orgasm. A comparison between the scores of control and experimental participants showed significant differences (CI = 99%) in all the dimensions. Thus, a worse sexual functioning has been observed in the drug consumer group. The adaptation of the Changes in Sexual Functioning Questionnaire-short form to drug-dependent individuals showed good psychometric properties.
