title: Patient adherence and adjustment in renal dialysis: a person x treatment interactive approach.
abstract: We classified 52 in-center hemodialysis patients and 34 self-treated, continuous ambulatory peritoneal dialysis (CAPD) patients on two latent variable indices reflecting patient coping style (i.e., "Information Vigilance" and "Active Coping"). The concurrent and prospective interactive effects of Dialysis Type and Coping Style were examined on patient dietary and medication adherence and on patient depression. In cross-sectional analyses, higher Information Vigilance was associated with better dietary adherence for CAPD patients but poorer adherence for In-Center Hemodialysis patients. No significant effects were found on a measure of medication adherence. Information Vigilance exerted a concurrent main effect on depression, such that higher scores were associated with less depression irrespective of dialysis type. Higher Active Coping scores were associated with lower residualized change in depression for both types of dialysis.
