Development of a child-rearing promotion of sexual abstinence scale (CPSAS) in Thai female adolescents at two Thai universities

Abstract

Purpose Child-rearing promoting sexual abstinence has strongly predicted sexual abstinence in Thai female adolescents, and it requires a valid and reliable measurement. However, no such instrument exists. This study aimed to develop a child-rearing promotion of sexual abstinence scale (CPSAS) and assess its validity and reliability.Design/methodology/approach The scale development consisted of two phases; scale construction and psychometric testing. Phase I included item generation extracted from a literature review and existing measurements. Items were reviewed by five-panel experts and were then selected by considering an inter-item correlation, corrected item-total correlation, factor loading and communality value from the exploratory factor analysis (n = 299). Phase II involved confirmatory factor analysis (CFA) for construct validity and scale reliability (n = 300).Findings The CPSAS, first, contained 25 items with four dimensions; assuring daughter to recognize parental love, teaching daughter sexual abstinence, convincing daughter to recognize parent's expectations of sexual abstinence and encouraging daughter sexual abstinence. Two items were then deleted after the experts reviewed, and six items were removed after item analysis. The CPSAS finally contained 17 items with a 4-point Likert scale. Psychometric testing provided acceptable results. CFA reported the fit indices; χ2 = 98.06 p = 0.083, df = 80, χ2/df ratio = 1.220, CFI = 0.996, TLI = 0.992, RMSEA = 0.027 and SRMR = 0.030. The standardized factor loadings were 0.499 to 0.908 (p < 0.05). The S-CVI was 0.96, and Cronbach's alpha coefficient was 0.93.Originality/value The CPSAS is a reliable and valid instrument for evaluating child-rearing promoting sexual abstinence in Thai female adolescents.
