Development and Testing of the Role-related Meaning Scale for Staff in Pediatric Oncology

The purpose of this study was to develop and test the Role-Related Meaning Scale for Staff in Pediatric Oncology (RRMS) to determine the internal consistency and the content and construct validity of this two-phase instrument. During phase 1 (item generation, content validation, and initial field testing), 23 nurses from two cancer centers participated, and during phase 2 (instrument testing), 89 nurses from one pediatric research center participated. The nurses completed either the RRMS only (phase 1) or six instruments including the RRMS (phase 2) to assess the following research variables: role-related meaning, group cohesion, organizational commitment, work satisfaction, and intent to leave. The RRMS was revised after phase 1 because the results yielded a ceiling effect and three overlapping items. The Cronbach alpha for the phase 2 total RRMS was .83, and four of the five hypothesized relations were confirmed (P = .04). Therefore, the RRMS was concluded to be an internally consistent instrument that has content validity and beginning construct validity. Future studies will examine whether the RRMS adequately measures the change in meaning brought about by interventions designed to increase role-related meaning among nurses.
