However, there are only a few developed scales among MSM in Thailand and they are not up to date. The objective of this study is to examine the reliability and validity of the HIV preventive behavior measure among Thai men who have sex with men (MSM).\n                    <ns3:bold>Methods<\/ns3:bold>\n                    The sample comprised 424 Thai MSM aged 25\u00a0years or older who had at least one sexual encounter in the past six months. The total sample was randomly divided into two equal subsamples: one used for exploratory factor analysis (EFA) to identify underlying structures, and the other for confirmatory factor analysis (CFA) to verify model fit. Cronbach\u2019s alpha was employed as the primary reliability coefficient because it reflects internal consistency, and the data collection was conducted only once. Convergent and discriminant validity were examined through Pearson\u2019s correlation coefficients with theoretically related and unrelated constructs to assess coherence and distinctiveness of the measure.\n                    <ns3:bold>Results<\/ns3:bold>\n                    The measure comprised nine items forming two components: (1) denial and avoidance of HIV risk, and (2) self-protective actions before and during sexual activity. CFA indicated an excellent model fit (\u03c7\n                    <ns3:sup>2<\/ns3:sup>\n                    \u00a0=\u00a036.56,\n                    <ns3:italic>p<\/ns3:italic>\n                    \u00a0=\u00a0.06, \u03c7\n                    <ns3:sup>2<\/ns3:sup>\n                    \/df\u00a0=\u00a01.46, GFI\u00a0=\u00a00.96, CFI\u00a0=\u00a00.98, RMSEA\u00a0=\u00a00.05), meeting recommended criteria for a valid psychometric model. Internal consistency was acceptable (Cronbach\u2019s \u03b1\u00a0=\u00a0.77).
