he purpose of the following four studies was to develop and begin the process of validating the Spirit at Work Scale. In the initial study, I outline the development of the 18-item SAWS and present the four-factor structure . Initial validation is documented through the next three studies. Speci fi cally, in Study 2, the factor structure is confi r med and convergent, and discriminant validity is demonstrated by correlating SAWS with measures expected to be related to it in various degrees. The knowngroups method is used to illustrate that SAWS scores differ between two groups. Convergent and discriminant validity continues to be demonstrated in Study 3 by correlating SAWS with personal well-being scales. Finally, Study 4 demonstrates SAWS’ temporal stability (or test–retest reliability) and sensitivity to change over time.
