Objective: This study evaluated the validity of the Dialysis Diet and Fluid Non-compliance Questionnaire as a self-report instrument for clinical practice. The DDFQ was designed to measure non-compliance behaviour with diet and fluid guidelines in patients treated with hospital based hemodialysis in Flanders (Belgium). Design: A multicentre cross-sectional study design was used. Sample: The convenience sample of this study included 564 patients (49.1% male, 50.1% female) from 10 dialysis centres. Median age was 68 years (Q1 = 21, Q3 = 90), median length of time in dialysis was 29 months (Q1 = 1, Q3 = 297). Instruments: The DDFQ is new developed patient self report instrument consisting of four sub-scales. Two for the measurement of non-compliance behaviour with fluid guidelines and two for the assessment of diet non-compliance. Variables / Measures: Criterion and construct validity of the instrument was substantiated using correlation techniques (Kendall’s Tau) between the DDFQ and biological (interdialytic weight gain) and biochemical (potassium, phosphate and serum albumin) ratings of non-compliance. Findings: Significant (p<0.0001) correlations between the DDFQ and biological and biochemical ratings were found. Conclusions / Implications: The results of this study support criterion and construct validity of the DDFQ. It is an easy to use instrument to measure non-compliance behaviour at a low cost in patients treated with hospital based hemodialysis. Further research in other countries is necessary to establish cross-cultural validity of the DDFQ.
