Many haemodialysis patients have problems limiting their fluid intake, and this might be influenced by their self-efficacy. Thus interventions to improve patients' self-efficacy might lead to an improvement in their adherence to fluid restriction. The fluid intake appraisal inventory (FIAI) evaluates patients' self-efficacy with regard to fluid intake. The aim of this study was to translate and validate the FIAI for use in the Netherlands. Four translators, seven experts, and four haemodialysis patients participated in the translation part of the study. Thirty-three patients from one dialysis centre in the Netherlands completed the Dutch FIAI. The instrument had good content validity (interdialytic weight gain was found to be negatively correlated with self-efficacy), internal consistency (Cronbach's alpha = 0.982), and stability (Spearman's rho = 0.823). These findings indicate that the Dutch FIAI can be used in clinical practice as a self-efficacy screening instrument for adult haemodialysis patients on fluid restriction.
