Recently, there were study suggested that TBI patients remained executive functions impairments that can affect patient’s cognitive, emotional, behavioral, social function and quality of life. However, there is minimal literature that explicitly addresses the effect of illness representations and executive functions on quality of life. The objective of this study was to investigate the effects of illness representations on quality of life in chronic TBI: executive functions as mediators. Purposive sampling was applied and participants were recruited from a medical center in south Taiwan during 2012 to 2014. Finally, 62 TBI patients agreed assessment. Outcome measures were the Executive Function Tests, Illness Representations Questionnaire, and World Health Organization Quality of Life-BREF Taiwan Version. The Regression Analysis were used to test mediation, Baron and Kenny (1986) proposed a four step approach in which several regression analyses are conducted and significance of the coefficients is examined at each step. Conduct a multiple regression analysis with illness representations and executive functions predicting quality of life. EFs of twenty-one group show mediator effect in twenty-seven group. When the consequences, time-line, and emotion of illness representations predict physical health domain, psychological domain, social relationships domain, and environment domain, Executive functions show mediator effect. Executive functions show mediator effect when illness representations predict quality of life. Future, it is worthy of attention to promote quality of life by improving the executive functions of TBI patients, and this result will provide treatment targets to reduce risk for poor outcome.
