| Annotation | The Chinese Dementia Quality of Life instrument (DQoL) was validated in a cross-sectional study involving 98 participants - 27 controls, 35 patients with questionable dementia (QD) and 36 patients with mild to moderate AD - and 51 paired family caregivers (20 FCs of QD patients, 31 FCs of AD patients). FCs were recruited to evaluate patients' DQoL using the parallel form. Internal consistency, construct validity and concurrent validity of the DQoL were examined. Findings indicate that the Chinese DQoL instrument has stable internal consistency, but only moderate validity when used in early to moderate AD patients with MMSE greater than or equal to 12. The DQoL and Self-esteem sub-scales were significantly different across the three dementia severity groups. While values of internal consistency of the DQoL and its five sub-scales were high for the ratings of both the patients and FCs, two inconsistencies were found in results of the factor analysis and the poor conceptualisation of patients' DQoL: the sub-scales of Self-Esteem and Negative affect. Global cognitive impairment and self-care problems significantly correlated with the patients' DQoL, while the patients' depressive symptoms and self-rate problems significantly correlated with the FCs' DQol. The Chinese DQoL reported by early to moderate AD patients had good reliability, but moderate validity because the patients' depressive symptoms did not correlate with the DQoL and the major sub-scales. Both patients' and FCs' rating on DQoL are important in research and treatment decision making. (RH). |
