Limitations
SECONDARY
This study has some limitations. The primary limitation is that it is a secondary analysis of a randomized clinical trial. Additionally, participant enrollment and nonresponse to the survey may have introduced selection effects, although study enrollment (70%) and the survey response rate (81%) were relatively high. Survey response latency may have affected perceptions of the intervention. Another limitation is that the survey question was a single, one-time measure that may not accurately reflect job satisfaction.
