“…Weiner et al [22], who constructed the scale, considered QUALID as a one-factor scale, as well as a Swedish group [38]. A Spanish version of the QUALID reported, however, a three-factor solution with a sufficient Cronbach’s alpha for each factor [48]. The variables in our ‘comfort’ factor were exactly the same as in the comfort factor in the Spanish study.…”

Aim: To study quality of life among the elderly with dementia in institutions. Methods: Patients above 60 years with dementia, 82 in nursing home and 74 in departments of geriatric psychiatry, were included. They were assessed with the Quality of Life in Late-Stage Dementia (QUALID); the Self-Maintenance scale, Mini Mental State Examination (MMSE) and Clinical Dementia Rating scale. Patient’s age, gender, previous medical and psychiatric history were recorded. Dementia was diagnosed according to ICD-10 criteria for research. Based on information in an interview with the patient and a carer and information in the patient’s record, a geriatric psychiatrist made a diagnosis of major depression according to DSM-IV, if present. Results: The patients’ mean (± SD) age was 82.9 ± 7.7 years, 103 (66%) were women. A factor analysis of the QUALID scale resulted in two factors: ‘discomfort’ and ‘comfort’. Three linear regression analyses were performed. Variables associated with lower quality of life (total QUALID score) were: a diagnosis of major depression (p < 0.001), lower score on MMSE (p = 0.032), impaired function in activities of daily living (p = 0.007) and female gender (p = 0.046). Variables associated with the ‘discomfort’ subscale score were: major depression (p < 0.001), lower score on MMSE (p = 0.006) and living in a department of geriatric psychiatry (p = 0.041). The ‘comfort’ subscale score was associated with impaired function in activities of daily living (p < 0.001). Explained variance for the three models was 34, 33 and 23%, respectively. Conclusion: Quality of life is diminished among elderly patients in institutions and the most marked correlates were a diagnosis of major depression, worse performance in activities of daily living and worse cognitive function.

“…The other items, namely ‘cries', ‘appears sad', ‘facial expression of discomfort', ‘appears physically uncomfortable', ‘verbalization suggests discomfort' and ‘being irritable and aggressive', appear more frequently the higher the score is. The scale has a good inter-rater reliability, an acceptable level of internal consistency and has been used in previous NH studies [27,28,29,30]. …”

“…The QUALID scale was developed by Weiner et al [27] to measure objective signs of qol according to Lawton's definition [3]. It consists of 11 items and has proved to be a reliable instrument in studies of pwd [28,29,30]. Four studies with a sufficient number of participants that aimed at examining the QUALID scale's factor structure used principal component analysis (PCA) [27,28,30,31].…”

Aims: To investigate which factors the Quality of Life in Late-Stage Dementia (QUALID) scale holds when used among people with dementia (pwd) in nursing homes and to find out how the symptom load varies across the different severity levels of dementia. Methods: We included 661 pwd [mean age ± SD, 85.3 ± 8.6 years; 71.4% women]. The QUALID and the Clinical Dementia Rating (CDR) scale were applied. A principal component analysis (PCA) with varimax rotation and Kaiser normalization was applied to test the factor structure. Nonparametric analyses were applied to examine differences of symptom load across the three CDR groups. Results: The mean QUALID score was 21.5 (±7.1), and the CDR scores of the three groups were 1 in 22.5%, 2 in 33.6% and 3 in 43.9%. The results of the statistical measures employed were the following: Crohnbach's α of QUALID, 0.74; Bartlett's test of sphericity, p <0.001; the Kaiser-Meyer-Olkin measure, 0.77. The PCA analysis resulted in three components accounting for 53% of the variance. The first component was ‘tension' (‘facial expression of discomfort', ‘appears physically uncomfortable', ‘verbalization suggests discomfort', ‘being irritable and aggressive', ‘appears calm', Crohnbach's α = 0.69), the second was ‘well-being' (‘smiles', ‘enjoys eating', ‘enjoys touching/being touched', ‘enjoys social interaction', Crohnbach's α = 0.62) and the third was ‘sadness' (‘appears sad', ‘cries', ‘facial expression of discomfort', Crohnbach's α 0.65). The mean score on the components ‘tension' and ‘well-being' increased significantly with increasing severity levels of dementia. Conclusion: Three components of quality of life (qol) were identified. Qol decreased with increasing severity of dementia.

Cross-cultural adaptation and psychometric validation of a Spanish version of the Quality of Life in Late-Stage Dementia Scale

Abstract: Our evaluation of the psychometric properties of the Spanish version of the QUALID indicates that it is a reliable and valid instrument with an adequate capacity to distinguish between different clinical status.
