Abstract:
Objective:To evaluate the application effects of two different item response modes in the Worker-Occupation Fit Inventory (WOFI) .Methods:From June to October 2022, a stratified cluster sampling method was adopted to collect and evaluate on-site data on worker-occupation fit among medical workers in two tertiary grade A general hospitals in Sichuan Province and Henan Province (1162 participants). Ordinal categorical item response (hierarchical item response) and dichotomous item response are two commonly used item response modes in psychometric measurement. Item response theory was used to analyze and compare the evaluation effects of the two item response modes in the WOFI. The generalized partial credit model and the 2-parameter logistic model were used to compare the item difficulty, discrimination, and scale information volume under different response modes.Results:The discrimination values range of the items in the WOFI under the hierarchical item response and dichotomous item response modes was 0.98 to 2.06 and 1.24 to 2.72, respectively, and the item difficulty values range was -4.61 to 1.15 and -1.25 to 0.08, respectively. Under the hierarchical item response mode, the amount of information on the WOFI was concentrated in the range of θ (the real ability or trait level of the subject) of -4 to 2, while under the dichotomous item response mode, it was concentrated in the range of θ of-2 to 2. The scale information volume was insufficient when θ was greater than 2 for both response modes. Conclusion:The discrimination of the items of the WOFI is relatively close under the two item response modes, and the overall information volume meets the evaluation criteria. However, under the hierarchical item response mode, the item difficulty range and information volume distribution are wider. Therefore, the WOFI is more effective and reliable when using the hierarchical item response mode.
