Abstract
This study examined the effects of the Big Five personality traits on support/strain exchange within older couples. Data of 1,775 older couples aged between 50 and 85 years in 2014 from the Health and Retirement Study were assessed, and actor–partner interdependent models were used. For the actor effects, all the five factors predicted their report on the spousal support/strain from the spouse; some differences between husbands and wives, as well as support and strain, were detected. For the partner effects, conscientiousness, agreeableness, and neuroticism predicted the support/strain provision reported by the partner. The findings of this study illustrate that certain personality factors work as predictors of spousal support/strain in older couples. The possible mechanism with regard to older adults’ personality and marital relationship was discussed.
