Background
Patients with kidney disease receiving dialysis are a highly vulnerable population. There is some evidence from small studies that Health-Related Quality of Life (HRQL) in these patients is influenced by psychosocial determinants, but their relevance for clinical outcomes is debated. We investigated whether Self-Efficacy (SE) and Social Support (SS) can explain differences in HRQL outcome domains over time in hemodialysis patients.
Methods
HRQL in 1264 participants from the CONVINCE randomized, controlled trial investigating hemodiafiltration versus hemodialysis were assessed, using screening and quarterly follow-up data up to 24 months. Measures included the MOS Social Support Scale, General Self-Efficacy Scale, Perceived Stress Questionnaire and PROMIS short forms for fatigue, physical function, pain interference and intensity, sleep disturbance, anxiety, cognitive function, depression, and ability to participate in social roles. SE and SS were included as independent variables and HRQL domains as dependent variables in a linear mixed effects model with random intercept and slope for SE and SS.
Results
Participants were 20-92 (M=62.33, SD=13.50) years old, 62.9% were male. Linear mixed effect regression models showed significant main effects for self-efficacy (β=.85-4.84, p<.001) on all HRQL domains. Main effects for social support were found for Cognition, Depression, Pain Intensity and Sleep (β=.27-2.17, p<.01). For time, significant main effects were found for Anxiety and Sleep (β=.56 & .50, p<.01). Significant SE x Time interactions were found for Anxiety, Depression and Sleep (β=.11-.19, p<.05). Significant SS x Time interactions were found for Cognition and Sleep (β=.17 & .18, p<.01).
Conclusion
Our results indicate that higher SE is associated with higher HRQL of dialysis patients over time. Effects of SE are larger than those of SS and larger than previously reported. This bears the chance to develop targeted psychosocial interventions to improve health outcomes when undergoing dialysis.
