An assessment of the construct validity of Ryff’s Scales of Psychological Well-Being: Method, mode, and measurement effects

This study assesses the measurement properties of Ryff’s Scales of Psychological Well-Being (RPWB)—a widely used instrument designed to measure six dimensions of psychological well-being. Analyses of self-administered RPWB data from three major surveys—Midlife in the United States (MIDUS), National Survey of Families and Households II, and the Wisconsin Longitudinal Study (WLS)—yielded very high overlap among the dimensions. These large correlations persisted even after eliminating several methodological sources of confounding, including question wording, question order, and negative item-wording. However, in MIDUS pretest and WLS telephone administrations, correlations among the dimensions were much lower. Past research demonstrates that self-administered instruments provide more valid psychological measurements than telephone surveys, and we therefore place more weight on the consistent results from the self-administered items. In sum, there is strong evidence that RPWB does not have as many as six distinct dimensions, and researchers should be cautious in interpreting its subscales.     

Parents’ marital disruption and its uneven effect on children’s academic performance—A simulation model

Although a substantial amount of social science research has examined the consequences of various life events, much less has been done to examine how the effect may be unevenly distributed. The present research takes children’s experiences of parents’ marital disruption as an example and demonstrates how a contaminated-distribution model may simulate a scenario in which the effect of parents’ marital disruption on children’s academic performance is unevenly distributed. Using test performance data from a nationally representative sample of 10,045 American adolescents, the study partitions the overall performance distribution among adolescents of divorce into an unaffected and a severe-effect distribution. The analyses report the estimated proportions of adolescents whose academic performance is severely affected by various levels. The findings also show that the proportions of adolescents whose school performance is affected by a fixed level remain relatively stable in three consecutive post-divorce waves.
