Introduction: Craving is considered both a diagnostic criteria and a prognosis factor in Substance Use Disorders (DSM – 5). Most rating scales for craving are available in English and no translation or adaptation into Spanish population has been made.
Objectives: Our main is to adapt and validate the PACS, OCDS-5 y ACQ-SF-R scales into Spanish population.
Methods: After a translation-back translation process, the three questionnaires were administered to 120 alcohol dependent patients that have been abstinent for the last four weeks. Reliability, construct validity and the convergent and predictive validity of the questionnaires was determined.
Results: We found a reliability of α> 0.80 in all scales. PACS and OCDS-5 showed a unifactorial structure, extracting three factors in the case of ACQ-SF-R. The convergent validity with the full version of the OCDS was high for PACS and OCDS-5 (r> 0.75) but lowest for ACQ-SF-R (r = 0.56). The predictive validity of all questionnaires in order to determine the risk of relapse in the first year of treatment was confirmed.
Conclusions: PACS, OCDS-5 and ACQ-SFR show good psychometric properties in its Spanish adaptation. Their short extension is an important feature of these questionnaires.
