Abstract
In this investigation, the serious leisure inventory and measure (SLIM) was developed from convenience and target samples. The multidimensional framework of serious leisure contains six qualities from which 18 operations were employed. With the use of a q-sort, an expert panel, and confirmatory factor analysis, the 72 item SLIM demonstrated acceptable fit, reliability and equivalence across samples. Mean differences and correlation patterns found between samples demonstrated preliminary evidence for the predictive ability of the new measure. The SLIM short form (54 items) demonstrated good model fit and construct validity. Future replications are needed to adequately address the psychometric complexities of the SLIM within the network of interrelated leisure constructs.
