Psychometric properties of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) in a population-based sample of Polish adults with type 1 and 2 diabetes.

BACKGROUND: The aim of the present paper was the assessment of the psychometric properties of the Polish language version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire applied in Poland among patients with type 1 (T1DM) or type 2 diabetes (T2DM). METHODS: The studies were carried out among 330 patients with diabetes including 115 with T1DM and 215 with T2DM. In all the patients the level of the quality of life was investigated using the Polish language version of the ADDQoL and the psychometric properties were determined taking into consideration internal consistency, the factor loading and intraclass correlations. RESULTS: It was demonstrated that the values of internal consistency determining the reliability of the Polish language version of the ADDQoL for the overall Cronbach's alfa coefficient were 0.92 in the studied patients with T1DM and 0.93 in the studied patients with T2DM and the values of the loading factor were respectively 0.39-0.79 and 0.35-0.81. In the study of the correlation between the components of the ADDQoL the correlation coefficients proved to be highly statistically significant: in patients with T1DM r = 0.46-0.74 and in patients with T2DM - r = 0.42-0.80. CONCLUSION: The Polish language version of the ADDQoL is a reliable tool useful for the assessment of the level of the quality of life of adult patients with T1DM or T2DM in Poland and is recommended to be used among Polish-speaking patients with diabetes.

Physical and mental health aspects of elderly in social care in Poland.

BACKGROUND: The objective of the study was to evaluate health aspects in elderly individuals in social, institutional, and home care in Poland. METHODS: A total of 300 elderly individuals in care in Poland were included in the study. The subjects were divided into three groups: residents of long-term care institutions (group I), residents of adult day-care homes (group II), and community-dwelling subjects (group III). Each group consisted of 100 subjects. Questionnaires evaluating the following physical and mental dimensions of health were used: SF-36 Health Survey, basic activities of daily living, instrumental activities of daily living, Geriatric Depression Scale, and Mini-mental state examination. RESULTS: It was found that the health aspects of the elderly varied depending on whether care was provided in an institutionalized or a home environment, and the lowest health status was found in the elderly receiving in-home care. Furthermore, home-based elderly indicated significant limitations in performing basic activities of daily living and instrumental activities of daily living, as well as a higher prevalence of depression and cognitive impairment. CONCLUSION: The elderly in long-term institutionalized care, both in a residential home and adult day-care homes, were characterized by a better physical and mental health status than those receiving in-home care. It seemed that worse health status, including the more frequent depression occurrence and cognitive function disorders in the elderly using the nursing care at their homes, was related to their multimorbidity, loneliness, and too-short duration of the care during the day.
