Barriers to Self-Management Reported by Study Participants: Bivariate (Spearman) Correlations With Outcomes
| Correlation Coefficients | |||
|---|---|---|---|
| Potential Barrier to Self-Management* | Mean Score (SD)† | Health Status | Physical Functioning |
| * Listed in order of addition to multivariate models. | |||
| † Scales 0 to 100 except as noted. Higher scores are consistent with being better off for a given domain, eg, better knowledge, fewer financial constraints, better patient-clinician communication. | |||
