The Multilevel Reliability and Interrater Agreement of the Nurse Practitioner Primary Care Organizational Climate Questionnaire.

It is critical to accurately measure and understand the nurse practitioner (NP) work environment in which individual NP information is gathered but decisions or inferences are made at an aggregated, group level. However, there is little research on preconditions of aggregating individual-level data into group level in nursing research. This study was conducted to assess the multilevel reliability and group interrater agreement (IRA) of the Nurse Practitioner Primary Care Organizational Climate Questionnaire. Secondary data analysis from a cross-sectional survey with 247 NPs in 112 practices across 6 U.S. states in 2018-2019 was used. The generalizability coefficients and values of IRA were acceptable (> .70), and values of ICC(1) were significant (.18-.38). Aggregating individual NP data to a higher group-level work environment construct is acceptable.
