An objective measure of psychological well-being (a previously understudied outcome for persons with dementia) was developed and tested as part of a longitudinal study (n= 96 participant pairs; n= 73 pairs remaining at 18 months). The reliability and validity of the Psychological Well-being in Cognitively Impaired Persons (PWB-CIP) scale was examined as a measure of one dimension of quality of life (QoL) as persons progress in the disease. The original 16-item PWB-CIP Likert-type scale required only five to 10 minutes to complete and was reduced to 11 items following factor analysis. Cronbach's alpha for the total scale was .79 at baseline and .82 at 18 months. Two subscales were identified: positive affect/interaction and negative affect/interaction. One item ('involved in a single activity for > five minutes') loaded on a different subscale at baseline (early disease stages) compared to 18 months (reflecting disease progression). The internal consistency of the two subscales remained acceptable across the two measurement intervals. Controlling for mental status, the PWB-CIP's construct validity was supported through significant relationships with depression, personal characteristics (personality), and the behavioral competence QoL dimensions at baseline and at 18 months. Because both rural (55%) and urban populations were sampled and the PWB-CIP was used across care settings, the findings support the PWB-CIP as a psychometrically sound measure of psychological well-being for diverse populations of persons with dementia.
