The primary objective of this study was to analyse the psychometric features, the reliability and the validity of the Spanish version of the Acceptance and Action Questionnaire-II (AAQ-II) adapted to the context of patients undergoing haemodialysis (HD). The secondary objective was to assess the relationship between PI and parameters related to the adherence to treatment and quality of life in these types of patients. Prospective cross-sectional study with patients on haemodialysis (n=186). The fat tissue index (15.56±5.72 vs. 18.99±8.91, P=.033), phosphorus levels (3.92±1.24 vs. 4.66±1.38; P=.001) and interdialytic weight gain (1.56±0.69 vs. 1.89±0.93, P=.016) were higher in patients with a higher PI score. Phosphorus levels (P=.013) significantly explained the variability of PI levels. PI was also shown as a significant predictor (P=.026) of the variability of phosphorus levels. The adaptation of the AAQ-II questionnaire to the HD context led to a valid and reliable measurement of PI in these types of patients and our results also seem to support the relationship between PI and health and quality of life parameters in patients with chronic conditions.
