Convergent and factorial validation of the Service Leadership Behavior Scale

Utilizing a sample of 4,486 Hong Kong undergraduates recruited from eight government-funded universities, this paper reports the findings of a cross-institution validation study on the Service Leadership Behavior Scale (ShortForm) with 65 items (SLB-SF-65). Specifically, we examined the internal consistency, convergent validity, as well as the dimensionality of the SLB-SF-65. Results of the exploratory factor analysis indicated that six factors could be extracted with 48 items retained in the trimmed version of the scale (SLB-SF-48) with a stable factor structure. Besides, the overall scale showed excellent internal consistency and was positively correlated to a myriad of theoretically relevant constructs. In short, the present findings underscored the adequacy of the trimmed Service Leadership Behavior Scale (SLB-SF-48) as an objective assessment to gauge whether one possesses the behavioral qualities of a Service Leader.
