Background and Aims:
People with intellectual disabilities are a vulnerable social group whose Physical health, quality of life and individual ability to live independently, have special important for them. Therefore, it is necessary to examine the factors that may increase the quality of life in this group. This study aimed to investigate the relationship between quality of life, executive functions, and physical function in people with intellectual disabilities.
Materials and Methods:
The sample consisted of 61 adults (34/31±8/895) with intellectual disability who were selected by convenience sampling method. The research method was descriptive-correlational. The 26-item WHO Quality of Life Questionnaire was used to collect quality-of-life data, the Barclay Executive Scale Short Form Scale was used to obtain executive function deficits, and the Physical Performance Short Battery Test was used to measure physical performance. In order to investigate the relationship between quality of life with executive functions and physical function, Pearson correlation method was used and to understand the contribution of each dimension to predict quality of life and regression model was used for independent variables of executive functions and physical function.
The results showed There is a significant relationship between the variables of quality of life with physical function (r = 0.31, p = 0.015), quality of life with executive functions (r = -0.37, p = 0.004) and physical function with executive functions (r = -0.42, p = 0.001). Also, 16% of changes in quality of life are explained through physical function and executive functions.
The findings of the present study showed the ability of executive function and performance in predicting the quality of life of people with mental disabilities. According to the obtained coefficients, it was shown that there is a positive relationship between quality of life and physical function, but there is a negative relationship between quality of life with executive functions and physical function with executive functions, and finally, predicting quality of life Executive function is possible.
