Abstract The purpose of this investigation was to determine to what extent family worldview and problem-solving communication style influence individual and family unit adaptation during retirement. A cross-sectional correlational survey design utilized Pearson correlations and stepwise multiple regressions. The sample consisted of 368 individuals representing 184 later life family units. Operationalized as family unit data, family worldview and family problem-solving communication style were examined in two series: (1) with outcome variable of family unit adaptation and (2) with outcome variable of individual adaptation. Scoring of family unit data was conceptually, procedurally, and analytically congruent. The investigation extended McCubbins' work into the later life family unit giving empirical support for two propositions of the Resiliency Model (M. A. McCubbin & H.I. McCubbin, 1993). This investigation also extended A. Antonovsky's (1987) work as the second study to apply the Antonovsky Sense of Coherence Scale to a family measurement. Conclusions are that although the way the family views the world is important during retirement, being affirmed by family members is more important. The investigation highlights the importance of a positive problem-solving communication style for a positive level of family adaptation. Individual adaptation during retirement was more influenced by family worldview.
