This study was designed to examine the relationship between perceived entrapment to depression and subjective well-being of women as family caregivers caring for elderly dementia patients. One hundred and sixty-nine women family caregivers were recruited from two high schools located in Seoul, Korea for this descriptive study. The instruments used were The Entrapment Scale, The Center for Epidemiology Studies Depression Scale (CES-D) and Subjective well-being scale. The score of perceived entrapment significantly correlated with depression and subjective well-being. The significant predictor of depression in women caregivers was perceived entrapment, 50.3% of the variance in depression. Also, perceived entrapment was predictor of subjective well-being in women caregivers, explaining 41.4% of the variance in depression. This study showed that perceived entrapment is an important predictor for depression and subjective well-being. Therefore, in order to reduce depression in women caregivers, it is necessary to design an intervention program that helps with coping and reduces perceived entrapment.
