BACKGROUND: Previous research indicates that routine inquiry or screening conducted by healthcare providers may significantly increase the identification of interpersonal violence. There is a lack of comprehensive instruments to routinely assess patients about interpersonal violence and violence against children in the household. The purpose of this study was to assess the content validity, face validity and reliability of the Questions on Violence (FOV) tool, an instrument specifically designed for routine inquiries about interpersonal violence in healthcare settings within the Swedish context.
METHODS: The content validity, face validity and reliability of the FOV instrument was assessed through (1) a content validity index with six experts in the field of intimate partner violence, (2) cognitive interviews with nine patients recruited from a primary healthcare facility, and (3) an evaluation of the test-retest reliability based on responses from 37(50.0%) university students. The intraclass correlation coefficient, model 2.1, was calculated to assess the degree of correlation and agreement between the two measurements.
RESULTS: Calculations based on the content validity index indicated that five out of seven items had excellent content validity (≥ 0.78). The average content validity index of included items was 0.88, which is slightly below the recommended threshold for excellent content validity. The results based on the cognitive interviews revealed that participants found the seven items to be relevant and easy to understand. Overall, the participants agreed that the concept of 'close relationships' primarily encompassed intimate partners, family members, and close friends. The value of the intraclass correlation coefficient was 0.85 (0.77-0.91; CI 95%), indicating good reliability with an interval of good to excellent test-retest reliability.
CONCLUSIONS: The results demonstrate that the seven-item FOV instrument has good content and face validity as well as good to excellent test-retest reliability. The current study provides healthcare professionals with a short yet comprehensive instrument for identifying patients who have experienced or perpetrated different forms of interpersonal violence.
