Objective : Assess the reliability and validity of the Thai translation of the CHOICE Health Experience
Questionnaire (CHEQ), which is the English-language questionnaire, developed specifically for End-stage-
renal disease (ESRD) patients. The CHEQ comprised of two parts, nine general domains of SF-36 (physical
function, role-physical, bodily pain, mental health, role-emotional, social function, vitality, general health,
and report transition) and 16 dialysis specific domains of the CHEQ (role-physical, mental health, general
health, freedom, travel restriction, cognitive function, financial function, restriction diet and fluids,
recreation, work, body image, symptoms, sex, sleep, access, and quality of life).
Material and Method: The authors translated the CHEQ questionnaire into Thai and confirmed the accuracy
by back translation. Pilot study sample was 10 Thai ESRD patients. Then the CHEQ (Thai) was applied to 110
Thai ESRD patients. Twenty-three patients had chronic peritoneal dialysis patients and 87 were chronic
intermittent hemodialysis patients. Statistical analysis included descriptive statistics, Mann-Whitney U test,
Student’s t-test, and Cronbach’s alpha.
Results : Construct validity was satisfactory with the significant difference less than 0.001 between the low
and high group. The reliability coefficient for the Cronbach’s alpha of the total scale of the CHEQ (Thai) was
0.98. The Cronbach’s alphas were greater than 0.7 for all domains, range from 0.58 to 0.92, except the social
function and quality of life domain (α = 0.66 and 0.575).
Conclusion : The CHEQ (Thai) is reliable and valid for assessment of Thai ESRD patients receiving chronic
dialysis. Its properties are similar to those reported in the original version.
