STABILITY AND CHANGE IN SUBJECTIVE WELL-BEING OVER SHORT-TIME PERIODS

Recent research has reported high stability for subjective well-being over periods as long as 9 years, concluding that well-being is essentially unaffected by environmental change. Other research has suggested well-being is responsive to change in life circumstances, and appropriate for use as an adaptational outcome variable. The present research examined the stability of well-being over short periods (3-6 months) using a range of well-being measures. Two different samples, mothers with young children and elderly persons, provided assessments of well-being and every day stressors (hassles) on three occasions, three months apart, as well as the personality measure, sense of coherence. Results demonstrated high consistency in well-being, but also found it to be influenced by environmental events and personality. With prior well-being controlled, current well-being was predicted by current hassles but not by past hassles. Coherence explained limited variance in current well-being with prior well-being controlled. Of the three factors, prior well-being, current hassles, and coherence, prior well-being was the strongest predictor of present well-being. These findings were consistent across the range of well-being measures, and replicated across the samples. Implications for the use of well-being as an adaptational outcome are discussed.
