Besides, role conflict and ambiguity appears also related to nurses occupational stress (Glazer, 1999; Peiro, 1994)
In this research we hypothesized that the Spanish version of NSS has the same structure as the original one. We also expected high positive correlations between NSS and STAI measures.
In our investigation we administered a Spanish version of the NSS to a sample of hospital nurses. We partially replicated the factorial structure found by Gray-Toft.
We also administered STAI to measure trait and state levels of anxiety.
In a second moment, we administered other questionnaires to search for relations among NSS and role conflict and ambiguity, and commitment.
The Scale and other questionnaires (Organizational Commitment of MOWDAY et al., 1982; Role Conflict and Ambiguity of Cortland et al., 1983) were administered to a sample of 195 nurses of 37 Departments on a general, public hospital.
We factor analyzed the scale items using a Principal Components analysis with quartimax rotation.
The analysis identified 9 factors. We show in Table 1 only loadings of 0.40 or higher. Two factors are related to the physical environment; five factors have to do with psychological environment, and two factors refer to social environment:
