Development and psychometric of a questionnaire for assessing of the causes of domestic violence in married men

This study aimed to design and assess a comprehensive questionnaire about the violence against women in an Iranian population. This study was a sequential exploratory mixed method.. According to the results of the qualitative Research and the revising of texts ,the primitive instruments were designed. Face validity ,content validity (by measuring content validity toward content validity index)and construct validity(by analysis of exploratory factor) were used to determine the validity of instruments and therefore internal consistency and test-retest method were used to determine reliability of instruments.In face validity 7items were excluded due to a score less than 1.5.In content validity by taking the 0.79 cut-off point to assess content validity index and 0.59 cut-off point to 34 items were elimented. And thus the number of items reduced to 58. validity by exploratory factor analysis was performed. Exploratory factor analysis suggested a six-factor model items including: Social factors undermining family stability, unhealthy life skills of couples, improper and insufficient teachings to couples , unhealthy treating of wives toward their husbands, Family support paradox, immediacy. These six factors explained 75% of variance violence against women. therefore internal consistency and test-retest method were used to determine reliability of instruments(α=0.987), (ICC=0.992).
Considering that all validity and reliability indexes of the questionnaire are reported in an appropriate level, violence against women’ questionnaire can be used as a valid and reliable questionnaire in measuring domestic violence in Iranian married men. However ,future research is recommended to evaluate usability of the study in other cultural settings.
