Background

Many patients who start peritoneal dialysis (PD) transition to hemodialysis after complications. Patient psychological factors may influence long-term PD success. Fixed mindset is the belief that ability cannot change, and growth mindset is the belief that knowledge and ability can grow and improve. Patient mindset may influence PD training, patient dialysis task execution at home, patient response to peritonitis, and modality persistence. The purpose of this study is to examine validity of the Health Mindset Scale (HMS) among adult PD patients.

Methods

Home dialysis units at two academic medical centers in the US are participating. The Health Mindset Scale (HMS), a 3-item Likert-based survey [scored 3-18, higher number indicates greater growth mindset], was administered at baseline, and then repeated for test-retest reliability. Instruments for resilience, depression, and health mindset specific to peritonitis were also administered at baseline. Spearman's rank correlation coefficients assessed correlations, and Cronbach's alpha assessed internal consistency.

Results

Mean age of 52 enrolled participants was 52yo [SD 16], with 48% male, 28% black, 40% with diabetes, and 87% with hypertension. Mean vintage was 628 days [SD 631]. Mean albumin was 3.9 gm/dL [SD 0.44]. Mean HMS score was 11.8 [SD 4.9] at baseline, and 13.7 [SD 3.5] at follow-up. HMS test-retest correlation was 0.43 [95% CI 0.05, 0.70]. Correlations between HMS and peritonitis mindset score, resilience, and depression were 0.64 [95% CI 0.41, 0.79], 0.26 [95% CI -0.03, 0.50], and 0.13 [95% CI -0.16, 0.40], respectively. Cronbach's alphas for baseline HMS, peritonitis mindset, depression, and resilience were 0.88, 0.83, 0.69, and 0.93, respectively.

Conclusion

Results results suggest good internal consistency of instruments for health mindset and peritonitis mindset, depression, and resilience in this sample of adult PD patients. Mindset variation suggests that an intervention to support growth mindset may be an important target to maintain PD as the ESKD treatment option.
