METHODS: A total of 25 items were developed based on literature reviews encompassing four main constructs: sexual intention, attitude, social norms and self-efficacy. The YSI-Q then underwent a validation process that included content and face validity, exploratory factor analysis (EFA), reliability analysis, and confirmatory factor analysis (CFA). This study was conducted on unmarried youths aged 18 to 22 years who were studying in colleges around Klang Valley, Malaysia.
RESULTS: EFA supported the four factor structure, but five items were removed due to incorrect placement or low factor loading (<0.60). Internal reliability using Cronbach's alpha ranged between 0.89 and 0.94. The CFA further confirmed the construct, convergent and discriminant validity of the YSI-Q with χ 2 = 392.43, df = 164, p sexual intention (five items), attitude (five items), social norms (six items) and self-efficacy (four items) of practicing sexual activity. YSI-Q was shown to be a reliable and valid tool to be used among Malaysian youths.
METHODS: Data for the study were drawn from a national survey entitled the "Determinants of Wellness among Older Malaysians: A Health Promotion Perspective" conducted in 2010.
RESULTS: According to the Mini-Mental State Examination education-adjusted cutoff points, 15.6% of the 1046 respondents were identified as having MCI. Older adults with MCI had a significantly lower level of sexual activity than the healthy cognitive group (chi-square = 50.20, P < .001, 32.5% vs 62.3%). The results of 3-step hierarchical logistic regression model revealed that MCI is significantly associated with decreased sexual activity in community-dwelling older adults, over and beyond demographic factors, and age-related medical conditions affecting sexual activity (odds ratio 0.33, P < .001, 95% confidence interval 0.23-0.49).
CONCLUSION: Findings from the present study support the significant role of cognitive functioning to perform sexual activity in later life.
