“…Hayes (2007) found that patients’ age, gender, and length of acquaintance with their NPs were correlated positively with the proximal outcome of patients’ satisfaction in interviews of 103 adult patients.

The different results may be due to differences in samples, variables, methods of data collection, measures, or methods of analysis.…”
