This research is a structural equation model forming study challenged to present a strategy in order to identify the national ankylosing spodylitis patient’s influence factor of health related life quality, verify the reciprocal relationship among them, and promote the health related life quality. The hypothetical model is based on Wilson and Cleary’s health related life quality model, and set by a literature review on ankylosing spodylitis patient’s health related life quality. The endogenous and exogenous factor of hypothetical model was composed of smoking intensity, biological physiological factor, environmental support, physical activity, symptom, depression, health perception, and health related life quality.
The data collection was made by people aged 19 and over who have visited the division of rheumatology at C university hospital, G city during January 13, 2015 to February 12 and ankylosing spodylitis patients who have maintained their stable medication at least for more than 4 weeks. The data collection has been made through a questionnaire, and the data of 275 has been included in the final analysis. The collected data has analyzed the characteristics of the object, descriptive statistics of research variable, tool reliability, correlation of variable measured and explorative factor by using SPSS 20.0 program, while has analyzed the confirmatory factor and verified the fit and hypothesis of hypothetical model by using AMOS 21.0 program.
The research result was as follows. The hypothetical model has not reached the recommended level of fit verification result, so it has eliminated the health perception variable based on the theoretical basis, added the path between the function and health related life quality before eliminating the unimportant path and completing the final modified model. The fit verification result of final modified model was χ²=164.634.583 (df=57, p<.001), GFI=.915, AGFI=.866, RMSEA=.083, CFI=.953, NFI=.930, TLI=.936, and showed relatively good fit.
In the final modified model, the biological physiological factor, environmental support, physical activity, symptom, depression and function accounted for ankylosing spodylitis patients’ health related life quality(57.6%). The exploratory factor representing an positively important relation to ankylosing spodylitis patients’ health related life quality was the function and depression, while the exploratory factor representing an positive and statistically important to the function was the symptom, and negatively important to physical activity. The factor representing an positive and statistically important relation to the symptom was the biological physiological factor, while environmental support and physical activity showed statistical and negatively important relation. Therefore, the lower the ankylosing spodylitis patients’ biological physiological factor, and the higher the environmental support, the higher the physical activity, the lower the symptom, the lower the functional limit, the lower the depression, the health related life quality has been more higher.
Based on this result, efforts to reduce the biological physiological factor, symptom, depression, functional limit when intervening nursing or developing program to improve the ankylosing spodylitis patients’ health related life quality, and to increase the environmental support and physical activity is considered to be more highlighted. And we suggest a repetitive experimental research that will be necessary to intervene the efficient strategic development of ankylosing spodylitis patients’ health related life quality and verify the effect of its program.
