| Annotation | An objective measure of psychological well-being was developed and tested as part of a longitudinal study in Illinois and Indiana of 96 participant pairs, 73 pairs remaining at 18 months. The reliability and validity of the Psychological Well-Being in Cognitively Impaired Persons (PWB-CP) scale was examined as a measure of one dimension of quality of life (QoL) as people progress with dementia. The original 16-item PWB-CP Likert-type scale required only 5-10 minutes to complete and was reduced to 11 items following factor analysis. Crohnbach'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 an activity for >5 minutes) loaded on a different subscale at baseline (early disease stage) 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-CP's construct validity was supported through significant relationships with depression, personal characteristics (personality), and the behavioural competence QoL dimensions at baseline and at 18 months. Because both rural (55%) and urban populations were sampled and the PWB-CP was used across care settings, the findings support the PWB-CP as a psychometrically sound measure of psychological well-being for diverse populations of people with dementia.
