Associations among perceptions of partner responses to disclosures about capitalization and support experiences and relationship satisfaction were examined over 1 year in 268 individuals in romantic relationships. Multilevel modeling indicated that capitalization and support perceptions covaried over 1 year, but they independently predicted contemporaneous relationship satisfaction and appeared to be compensatory processes. However, with increasing relationship duration, support perceptions became more strongly associated with relationship satisfaction, whereas capitalization perceptions became less strongly associated with relationship satisfaction, suggesting that capitalization perceptions may play less of a buffering role with time. Results suggested that perceiving partners as interested and enthusiastic in the face of triumph, and as caring and supportive in the face of difficulties, serve important and independent relationship maintenance functions.
