OBJECTIVES: to develop and conduct a pilot test of a risk detection instrument for sexual domestic violence among schoolchildren aged 9 to 11 years, entitled the Risk Detection Instrument - Sexual Domestic Violence (IDR-VSD).
METHODS: this is a mixed method study conducted between January 2019 and December 2022, following the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines. The qualitative phase included a consensus technique with nine interprofessional experts and cognitive interviews with the target population, including schoolchildren with impairment. A pilot test was conducted with 109 participants, and internal consistency, reliability, and factor structure were analyzed.
RESULTS: the initial version comprised 22 items with playful elements, distributed across four dimensions (biological, psycho-relational, social, and ecological). The intraclass correlation coefficient was 0.602 (95%CI=0.48-0.70; p<0.001). The overall Cronbach's alpha was 0.602. After correcting the item-total correlations, the overall alpha increased to 0.654 for 18 items. One item with a measure of sampling adequacy below 0.50 was removed. Exploratory factor analysis was performed with 17 items, distributed across five factors that explained 53.76% of the total cumulative variance, in accordance with the theoretical model.
CONCLUSION: the IDR-VSD demonstrates favorable measures of reliability and factor structure, despite the complexity of the studied phenomenon.
