| Summary: | INTRODUCTION: The newly developed Sexual Intention Questionnaire for Adolescent Boys (SIQ-AB) is an adapted tool from the Youth Sexual Intention Questionnaire (YSIQ) and Theory of Planned Behaviour (TPB), aimed to assess the influence of knowledge, permissive attitude, social norms, and self-efficacy toward the sexual intention. Thus, the aim of this study was to validate the newly developed SIQ-AB to
determine Malaysian adolescent boys’ sexual intention. MATERIAL AND METHODS:
The SIQ-AB validity and reliability were assessed in this study. A total sample of 252 (Exploratory Factor Analysis, n=126 and Confirmatory Factor Analysis, n=126) among
adolescent boys from Serian and Kota Samarahan, Sarawak were included in this study. The exploratory factor analysis (EFA) assessed three constructs of sexual intention which include attitude, self-efficacy, and social norms with a 4-point Likert scale with a total of 19 items. The confirmatory factor analysis (CFA) assessed the TPB constructs of sexual intention, attitude, self-efficacy, and social norms with a 4-point Likert scale with a total of 19 items adopted from YSI-Q. RESULTS: The four-factor structures were supported by the EFA which had 19 items which accounted for 65.79% of the variation overall. Four items were removed due to improper positioning or low factor loading (<0.50), even though EFA supported the four-factor structure. Using Cronbach’s alpha, internal reliability varied between 0.77-0.89. Construct, convergent and composite validity of the SIQ-AB were further validated by the CFA with χ 2=199.0, df=129, p<0.001, χ 2/df =1.54, CFI=0.98 and TLI=0.98 and RMSEA=0.06. CONCLUSIONS: The
result proved that the SIQ-AB instrument is a valid and highly reliable tool to assess adolescent boys' sexual intention. |
