Development and Psychometric Evaluation of a Questionnaire to Assess Attitudes Towards Invisible Gender‐Based Violence (Q‐AIGV).

Objective: To develop and psychometrically evaluate a questionnaire to assess attitudes towards invisible gender‐based violence (Q‐AIGV). Background: Invisible gender‐based violence is defined as discriminatory attitudes and beliefs towards women that are culturally accepted and normalised in society. Methodology: This is a cross‐sectional descriptive observational study. The development of the initial version of the questionnaire, a pilot study (N = 63) and a final validation study (N = 1264) were carried out. Reliability, validity, stability and readability were tested. Results: Exploratory factor analysis revealed that the Q‐AIGV is composed of 15 items distributed in three factors. Known‐groups analysis detected significant differences in two groups with different characteristics (age and relationship duration). Criterion validity indicated the existence of a moderate and significant correlation (r = 0.469; p < 0.001) between the mean score of the Q‐AIGV and the 'Scale of Attitudes towards Gender‐based Violence'. The Q‐AIGV's content validity index (CVI‐t = 0.96) and internal consistency (α = 0.906) were excellent. Conclusion: The Q‐AIGV showed very good results for reliability, validity, stability and readability. This suggests that the Q‐AIGV could be a good tool for assessing attitudes towards invisible gender‐based violence. [ABSTRACT FROM AUTHOR]
