This study provides evidence of reliability and validity for the Leisure Interest Questionnaire (LIQ; J. C. Hansen, 1998). Undergraduate students completed the LIQ and Strong Interest Inventory (SII; E. K. Strong Jr., 1927) at Time 1 and the LIQ 5 weeks later. The internal consistency and test-retest reliability of the LIQ scales were calculated. Evidence of construct validity was inferred from (a) intercorrelations among the LIQ scales and (b) correlations between LIQ and SII. A second sample of undergraduates completed the LIQ and the Leisure Activities Blank (G. E. McKechnie, 1975) to provide evidence of criterion validity. An exploratory factor analysis and a multidimensional scaling analysis of the LIQ scales provided information about the structure of leisure interests.
