The purpose of this study is to examine the interrelationships among perceived health status, learned resourcefulness, the level of depression and the level of quality of life in older adults who living alone. A cross-sectional correlation design was used to examine the effects of demographic variables, perceived health status and learned resourcefulness on depression and quality of life. Data were collected from a purposive sample of 79 community-dwelling elders who living alone. All of the subjects lived in Shih-Lin area in Taipei and were interviewed by the investigator directly.
The data collected were analyzed using correlation and multiple regressions. The finding indicated that the two variables “perceived health status and learned resourcefulness” are negatively correlated with the level of depression（r =-0.77 & -0.73, p<0.001） and positively corrected with the level of quality of life（r =0.58 & 0.73, p<0.001）. In addition, the level of depression is negatively correlated with the level quality of life（r =-0.88, p<0.001）. Although quality of life was associated with demographic variables, only the factors of perceived economics status（p<0.01） and religions（p<0.05） could explain the variance of quality of life with significance. Moreover, a hierarchical regression was performed to partial out the influence of demographic variables on the relationship between independent variables （perceived health status and learned resourcefulness）and dependent variables（depression and quality of life）. As expected, The independent variables （perceived health status and learned resourcefulness）have direct negative effect on depression level. Also, the variables of perceived health status and learned resourcefulness have direct positive effect on quality of life.
Thus, this study suggested that nursing intervention should facilitate learned resourcefulness by teaching or reinforcing the skills constituting resourcefulness. In addition, future research should examine the interaction effects of perceived health status and learned resourcefulness on depression and quality of life among a large sample of older adults.
Key words：community-dwelling older adults living alone； perceived health status； learned resourcefulness； depression； quality of life
