Abstract
This study examines the structural validity of innovative work behavior (IWB) among employees in the automotive manufacturing industry using second-order confirmatory factor analysis (CFA). Data were collected from 250 employees in an automobile manufacturing company located in the Eastern Economic Corridor (EEC), Thailand, using proportionate stratified sampling. The measurement properties of IWB were first assessed through first-order CFA, followed by second-order CFA to examine whether the underlying dimensions converge into a higher-order construct.
The results indicate that innovative work behavior can be appropriately conceptualized as a second-order construct consisting of three interrelated dimensions: idea generation, idea promotion, and idea realization. The measurement model demonstrated a good fit to the empirical data (χ²/df = 1.940, CFI = 0.964, TLI = 0.953, RMSEA = 0.061, RMR = 0.022), and the first-order dimensions exhibited substantial second-order factor loadings (0.842–0.911). These findings suggest that innovative work behavior is a multidimensional latent construct with internal coherence and that the measurement model is appropriate for assessing innovative work behavior in manufacturing contexts characterized by standardized work processes. The findings also provide practical implications for evaluating and developing employees’ innovative work behavior, particularly in contexts emphasizing the implementation of new ideas and continuous process improvement.
