Background: At the international level PREMIS -"Physician Readiness to Manage Intimate Partner Violence Survey"- is amongst the most comprehensive instruments to evaluate primary health care professionals' readiness. The aim of this study is to assess the reliability, internal consistency and construct validity of the Spanish version of this questionnaire.
Methods: After translation, back translation and assessment of content validity of the questionnaire, 200 questionnaires were distributed to medical doctors and nurses working in 15 primary health care centres located in 4 autonomous regions (Comunidad Valenciana, Castilla León, Murcia, Cantabria), in 2013. Cronbach's alpha, intraclass correlation and rho Spearman coefficients were calculated.
Results: the Spanish version of PREMIS encompasses 64 items. Cronbach's alpha coefficient was greater than or close to 0.7 in most of indices. Intraclass correlation coefficient of 0.87 and Spearman coefficient of 0.67 showed a high reliability. All correlations for the scale of Opinions, which is the only one that was considered factorial structure of the questionnaire PREMIS, were higher than 0.30.
Conclusions: the Spanish version of PREMIS obtained good internal validity, high reliability and predictive self-reported capacity of medical practitioners and nurses in Intimate Partner Violence cases in PHC centers.
