Tayvan'daki Yetişkinlerde Algılanan İş Yükünü Değerlendirmek İçin Geleneksel Çince NASA Görev Yük İndeksi'nin Çapraz Kültürel Uyarlaması ve Doğrulanması

Özet (abstract)

Background Perceived workload is central to occupational health, ergonomics, and rehabilitation research, yet no guideline-based Traditional Chinese version of the NASA Task Load Index (NASA-TLX) has been available for Taiwan and other Traditional-Chinese-speaking settings. Objective To cross-culturally adapt the NASA-TLX into Traditional Chinese (NASA-TLX-TC) and evaluate its measurement properties in Taiwanese adults. Methods In a psychometric secondary analysis, 114 community-dwelling adults aged 20–50 years completed the NASA-TLX-TC on three consecutive days. Within the COSMIN framework, we examined content validity, internal consistency, structural validity (exploratory factor analysis with parallel analysis), test-retest reliability (intraclass correlation [ICC]), measurement error, and construct validity (seven a priori hypotheses involving sleep, mood, and shift work). Results The content validity index averaged 0.88 and Cronbach's α was 0.83. The six dimensions loaded on a single factor (55.8% of variance). The three-day average score showed good reliability (ICC[A,k] = 0.83), whereas single-day reliability was moderate (0.62); the minimal detectable change was 32 points. Six of seven construct-validity hypotheses were supported; the shift-work difference was in the predicted direction but nonsignificant. Internal consistency and convergent validity were stable across subgroups. Conclusions The NASA-TLX-TC showed good reliability and initial construct validity and is suitable for group-level occupational-health, ergonomics, and rehabilitation research; multi-day averaging is recommended for individual assessment.
