A study was conducted to examine whether the potential factors can predict quality of life among persons with automatic implantable cardioverter defibrillator. In all 120 automatic implantable cardioverter defibrillators were recruited from super tertiary hospital in Bangkok. The research instruments included 1) demographic data 2) frequency of automatic implantable cardioverter defibrillator shock questionnaire 3) multidimensional scale of perceived social support Thai version 4) Mishel uncertainty in illness scale-community version Thai version 5) knowledge of automatic implantable cardioverter defibrillator test 6) EQ-5D-5L. All research instruments were tested for content validity and reliability. Cronbach’s alpha coefficients were .91, .90, .78 and .81, respectively. Data were analyzed using multiple linear regression.
The results were as follows: The majority of subjects (75%) were male; average age was 51.50 years. The mean score of Quality of life was high (M=.86, SD=.17). Only two variables were significant predictors. Uncertainty of illness had significant negatively related with quality of life (Beta=-.327, p=.001). Frequency of AICD shock was negatively correlated with quality of life (Beta=-.248, p=.005). These two variables accounted for 24.7% of the explained variation in quality of life at statistical significance of p<.05 (F (4,119)=9.455, p=.000, R=.497, R2=.247, R2Adjusted=.221).
