<h4>Background</h4>Turnover intention predicts actual turnover and is vital in nursing. Despite many tools to assess turnover intention, few are culturally adapted or validated for Thai nurses.<h4>Purpose</h4>This study aimed to translate, culturally adapt, and evaluate the psychometric properties of the Thai version of the Turnover Intention Scale (T-TIS).<h4>Methods</h4>A two-phase methodological study was conducted. Phase 1 involved translating and cross-culturally adapting the original scale in accordance with established international guidelines. Phase 2 evaluated the psychometric properties of the translated instrument among 1005 registered nurses at two tertiary government hospitals in Thailand. Content validity, known-group validity, confirmatory factor analysis (CFA), internal consistency, and Rasch analysis were assessed.<h4>Results</h4>The T-TIS demonstrated excellent content validity (I-CVI = 1.00; S-CVI = 1.00). Known-group validity was supported by significant differences in T-TIS scores across groups defined by burnout, emotional labour, work-family conflict, nursing practice environment, work engagement, and effort-reward imbalance (all p < 0.001; η 2 = 0.05-0.30; Cohen's d = 0.93). CFA reasonably supported the hypothesized unidimensional structure, with acceptable model fit (CFI = 0.96, TLI = 0.92, SRMR = 0.04), although the RMSEA indicated marginal fit (0.09). Internal consistency was satisfactory (Cronbach's α = 0.77; McDonald's ω = 0.78). Rasch analysis further supported the scale's measurement properties, demonstrating acceptable item fit (infit/outfit MNSQ = 0.77-1.27), acceptable person separation index (0.77), and strong item separation (17.00).<h4>Conclusions</h4>The T-TIS is a reliable, valid instrument for assessing turnover intention among Thai nurses, providing a practical tool for workforce monitoring, retention research, and policy in Thailand.
