Abstract

This dissertation has three parts. Firstly, a literature review (n=43) on predictors of quality of life in persons with stroke in China and Western countries. Secondly, a cross-cultural adaptation and validation of the Life Satisfaction Checklist-11 (LiSat-11) among persons with stroke in China (n=60). Thirdly, a prospective longitudinal study on the activities of daily living (ADL) and life satisfaction in persons with stroke (n=32) in China 3 years after discharge from rehabilitation and to identify the predictors of life satisfaction.

Main results: Predictors of QoL included Demographic factors : age, gender, marital status, education level, socioeconomic status; Clinically related factors : severity of stroke, physical function, depression/anxiety, cognitive impairment, incontinence, and other comorbidities; Environmental factors : residential status, social support, social participation; and Individual factors : coping strategies and self-perception. Interdependency, such as being married and resident at home, influence the perception of QoL positively in Chinese survivors, whereas in Western societies the individuals’ independence is a stronger predictor.

The Chinese version of LiSat-11 demonstrated good internal consistency and had moderate to high correlations with 36-Item Short-Form Health Survey in a concurrent validity test. High correlations were also found between LiSat-11 and Hospital Anxiety and Depression Scale in a convergent validity test.  There were low correlations with National Institutes of Health Stroke Scale, Barthel Index (BI) and modified Rankin Scale in divergent validity tests. 

ADL assessed by BI increased significantly within 3 years compared with that at discharge. The total score and most items of LiSat-11 indicated low satisfaction and remained relatively stable, except for ‘sexual life’. Life satisfaction at 12 months was predicted by the severity of the stroke, marital status, and returning to work, while life satisfaction at 3 years was predicted by the degree of disability. Age was found to be a predictor for items ‘Vocational’ and ‘Leisure’ situation.

In summary: The results demonstrate that most predictors of QoL in stroke survivors were the same in China and the Western countries. However, the differences that existed in QoL were influenced by the individualistic and collectivistic cultural differences. The LiSat-11 Chinese version is a reliable and valid measure for assessing the life satisfaction of persons with minor to moderate stroke in China. Functional independence increased after discharge from rehabilitation, while life satisfaction was low and maintained low at 3 years post rehabilitation. The severity of the stroke, disability, marital status, and possibility to return to work are predictors of life satisfaction after stroke.
