Objective: To psychometrically evaluate the Oppressed Group Behaviors Scale (OGBS) using data from 912 employed registered nurses in the state of Massachusetts, USA. Design: The OBGS structure was confirmed with a sample of 912 employed registered nurses in the state of Massachusetts. The sample was randomly split into two equal samples. The exploratory sample was used to derive the underlying components; the confirmatory sample was used to validate the component structure. Population, Sample, Setting, Years: Participants included a randomly selected sample of 912 employed registered nurses who agreed to participate in the study after receiving a request to participate in the study by mailed letter and survey (21% response rate). Methods: Psychometric analysis of the 42-item the OGBS included 1) a cross-validation procedure was used comparing the exploratory group (n=452) to the confirmatory group (n=452) to establish the factor structure of the OGBS and reliability of the factors. Then the OGBS factor validity was evaluated. Findings: Two components, "Internalized Sexism" and "Minimization of Self" behaviors, were identified in the factor analysis, explaining 48% of the variance in the exploratory sample and 52% in the confirmatory sample. Cronbach alpha for the factors was °Ý .74 in both samples. Validity was supported by factor score mean differences associated with age, clinical specialization, and nursing role (p°Ü .05) and significant correlations with the Silencing the Self Scale-Work version (STSS-W). Conclusions: The OGBS is a reliable and valid measure of oppressed group behaviors for registered nurses in Massachusetts. Implications: The OGBS can be used to provide specific information about oppressed behaviors of registered nurses. This information can be used to develop educational intervention programs that encourage nurses to confront internalized viewpoints or beliefs that support devaluing nurses' work in healthcare settings advancing the nursing research agenda.
