Opposite-Sex Relationship Questionnaire for Male Adolescents: Development and Psychometric Evaluation

Abstract

We used a mixed-methods, sequential, exploratory design. In the qualitative phase, an in-depth interview approach was used to identify the properties and dimensions to be included in the Opposite-Sex Relationship Questionnaire for Male Adolescents (OSRQMA). In the quantitative phase, the psychometric properties of the OSRQMA were evaluated according to the concepts of face, content, and construct validity. Reliability and stability were assessed with Cronbach's alpha (α) and McDonald's coefficient omega (ω), and with test–retest analysis respectively. A preliminary questionnaire was developed, including 61 items that emerged from the qualitative phase of the study. Based on the impact scores for face validity, and the cutoff points for the content validity ratio (CVR) and content validity index (CVI), the preliminary questionnaire was reduced to 53 items. The Kaiser criteria (eigenvalues >1) and scree plot tests demonstrated that 22 items forming four factors, which were labelled ‘innate predilection’, ‘abstinence’, ‘family attitudes’, and ‘peer pressure’, were optimum, accounting for an estimated 53.449% of the variance. These scales had acceptable levels of internal consistency (α = .854, ω = 0.977) and stability (r = .892, p < .001).
