Abstract
Limited research exists assessing problem-solving capabilities among caregivers of individuals with memory loss using a validated instrument. To address this gap, the current study evaluated the psychometric properties of the Problem Solving Inventory (PSI) using data at baseline and 8 weeks from a randomized controlled trial among caregivers (N = 78) of community-dwelling individuals with memory loss. Participants were mainly White (85.9%), female (71.8%), and on average age 66.5. Cronbach's alphas ranged from 0.84 to 0.92 for the subscales and overall PSI. Test-retest reliability over 8 weeks ranged from 0.44 to 0.56. Five factors were retained through exploratory factor analysis. Spearman's correlations showed convergent validity and discriminant validity between scores on the PSI and Beck Depression Inventory®-II (r = 0.32, p < 0.01), the Self-Efficacy for Managing Chronic Disease Scale (r = -0.44, p < 0.001), and the Newest Vital Sign questionnaire (r = -0.07, p > 0.05). Findings show that the PSI is reliable and valid in assessing problem-solving capabilities among caregivers of individuals with memory loss. [Journal of Gerontological Nursing, 44(6), 25-32.].
