본 연구의 주된 관심은 지체장애인들이 신체활동을 통해 변화되는 심리적 웰빙의 과정을 탐색하는데 있다. 이를 위해 지체장애인의 신체활동수준과 신체지각 및 심리적 웰빙간의 관계를 일련의 선행연구 결과를 토대로 가설적 연구모형을 설정하고 실증적으로 분석하였다. 자료수집은 편의표본 추출법과 판단표집법에 의한 만 20세 이상의 지체장애인 546명을 대상으로 하였으며, 반응자료는 SPSS와 AMOS 프로그램을 활용하여 측정변수에 대한 탐색적․확인적 요인분석 및 신뢰도를 검증하고 가설적 연구모형의 이론적 적합성과 변수들 간의 유의성을 확인하였다. 아울러 최적 예측모형을 제안하기 위해 x² 차이검증을 활용하여 다음과 같은 결과를 도출하였다. 첫째, 가설화된 연구모형의 적합도 평가 결과, 측정변수들 간의 구조적 관계는 타당한 것으로 확인되었다. 둘째, 연구모형의 경로계수 평가 결과, 지체장애인의 신체활동수준이 높을수록 자기신체지각 수준이 높았으며, 자기신체지각 수준이 높을수록 건강지각 수준과 심리적 웰빙 수준도 높았다. 셋째, 최적 예측모형을 탐색한 결과, 신체활동수준에 따른 건강지각 경로, 신체활동수준에 따른 심리적 웰빙 경로, 건강지각에 따른 심리적 웰빙 경로가 제거되고, 신체활동수준이 자기 신체지각에 영향을 미치며, 자기신체지각은 건강지각과 심리적 웰빙에 영향을 미치는 경로가 보다 적합하였다. 이러한 결과는 지체장애인의 심리적 웰빙과 건강신념이 신체활동을 통해 얻어지는 자기신체지각의 긍정적 변화에 의해 매개됨을 시사한다.
The purpose of this study was to analyze of relationships of physical activity level to
physical perception, health relative quality of life and psychological well-being in individuals
with physical disabilities. To achieve the purpose of the study, the researcher set
hypothetical structure models based on previous researches, and evaluated the path
coefficients among related variables, assessed the fitness of the models, tested the
hypotheses, and analyzed causal effects, and finally proposed the optimal estimation model
that can predict physical disabled people’s psychological well-being according to physical
activity level. Data were obtained from 546 physically handicapped individuals aged over 20
and were selected through convenience sampling and judgmental sampling. For data
analysis, this study conducted frequency, correlation, test-retest, paired t-test, Cronbach’s α,
exploratory factor analysis, confirmatory factor analysis and structure equation modeling
analysis. In addition, x² test was performed to propose an optimal prediction model and the
follow results were derived. First, according to the results of evaluating the goodness of fit
of the hypothesized research model, the structural relation among measured variables was
found to be valid. Second, according to the result of evaluating the path coefficient of the
research model, the physical self perception level was higher when the physical activity
level was high, and the health relative quality of life level and the psychological well-being
level were higher when the physical self perception level was high. Third, according to the
result of searching for the optimal prediction model, the paths from physical activity level
to health relative quality of life, from physical activity level to psychological well-being and
from health relative quality of life to psychological well-being were removed. In addition,
the physical activity level affected physical self perception, and the paths optimal for
physical self perception were those affecting health‐related quality of life and psychological
well-being. These results suggest that, in individuals with physical disabilities, psychological
well-being and health related quality of life are mediated through positive change in
physical self perception obtained from physical activities.
