Systematic review of dating violence questionnaires in Ibero-America and evaluation of their measurement properties.

Being a victim or perpetrator of dating violence has been associated with poor mental health, substance abuse, and sexual risk behaviors. The aim of this study was to carry out a systematic review and to evaluate the quality of the measurement properties of dating violence questionnaires, created or adapted in Ibero-America from 1981 to 2017, for a population aged 12 to 29 years and published in Spanish, English, Portuguese or French. The search was conducted in PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO and included manual searches. Two independent researchers conducted both the systematic review and the evaluation of measurement properties. Of 5,812 articles identified, 22 studies involving 16 different questionnaires of dating violence were included. In general, the questionnaires showed evidence of internal consistency, content validity and construct validity, although no study presented evidence of criterion validity, reproducibility, sensitivity, or floor and ceiling effects. Among the cross-cultural adaptations, 42% of them included translation, back translation, committee of experts in translation and piloting. Two questionnaires created, CMN and VADRI/Spain-Mexico and two adaptations of the same questionnaire CTS/Brazil-Mexico received the highest scores .
