A total of 248 students from one Southeastern U.S. middle school responded to measures of global and domain-based life satisfaction on three occasions, reflecting 5-month, 7-month, and 1-year time intervals. Alpha coefficients were all above 0.80 for each global and domain-based score on each occasion. The test--retest coefficients were variable, underscoring the importance of contextual factors in life satisfaction reports. Nevertheless, with the exception of the Friends domain, the retest coefficients for the global and domain-based scores all exceeded 0.50 across all three intervals, suggesting a moderate degree of stability yet potential sensitivity to changing life circumstances.
