The relationship between job satisfaction and life satisfaction has been heavily researched over the years. In spite of this research interest, results have not proved conclusive in demonstrating the causal nature of the relationship. In the present study, a causal model was hypothesized and tested that involved simultaneous consideration of cross-sectional and longitudinal effects between job and life satisfaction. This type of analysis has not previously been conducted and allows the strongest con- clusions to date regarding the causality between these constructs. Results based on a national prob- ability sample of workers indicated that job and life satisfaction were significantly and reciprocally related. The cross-sectional results suggested a relatively strong relationship between job and life satisfaction, but the longitudinal results suggested a weaker relationship over a 5-year period, partic- ularly with respect to the effect of job satisfaction on life satisfaction. The meaning of these results in the context of past research on the job satisfaction-life satisfaction relationship is discussed. Recently, Tail, Padgett, and Baldwin (1989) provided the first meta-analytic estimate of the relationship between job satisfac- tion and life satisfaction. Using correlations from 34 studies, Tail et al. (1989) estimated the average corrected correlation between the constructs to be .44. The authors concluded their review with this comment: "On the basis of the substantial rela- tionship between job and life satisfaction documented here, fur- ther explanatory research of this nature is now clearly war- ranted" (p. 505). In a recent review of the literature, Rain, Lane, and Steiner (1991) held that although Tail et al.'s study was use- ful in providing an overall assessment of the job satisfaction- life satisfaction relationship, it did not address the direction of causality between the constructs. Rain et al. argued that more efforts investigating the causality between job and life satisfac- tion were needed. Thus, despite extensive research, the critical question con- cerning what the direction of influence between job and life sat- isfaction is remains unanswered. The correlation estimated in Tait et al.'s (1989) meta-analysis suggests that a positive rela- tionship exists, but this study provided no information regard- ing whether job satisfaction causes life satisfaction, life satisfac- tion causes job satisfaction, or the two constructs are mutually causative. A causal influence from life satisfaction to job satis- faction is supportive of the dispositional perspective (Judge & Hulin, in press; Judge & Locke, 1993; Staw, Bell, & Clausen,
