Description: In testing the Lazarian framework, the purposes of this study were (1) to develop a measurement of psychological stress focusing on individual perception, that was used (2) to assess the extent to which the intensive care unit (ICU) environment was stressful for both patients and nurses and (3) to determine if the ICU environment was more or less stressful for patients and nurses than a nonintensive care unit (NICU) environment.

Data was collected on patient and nurses in ICU and NICU. SEARS III (Harris, 1984), a 22 item semantic differential in its third revision was designed to measure perceived environmental stress. State anxiety was measured by the State Anxiety Inventory STAI (Spielberger, et al., 1970) and the Affective Adjective Check List AACL (Zuckerman, 1960). The total sample (N = 326) was comprised of patients and their assigned nurses from 14 units in 3 hospitals. Patient subjects were postoperative English reading adults who had been hospitalized on their respective units for at least two days, who had some type of activity restriction and who received a score of 7 or more on the Mental Status Questionnaire (Kahn et al., 1960). Nurse subjects were limited to female RN's from all shifts, who worked at least three months on their assigned units and who were caring for the patient subjects.

In testing eleven hypotheses with t-tests and discriminant analyses, it was determined that differences existed between the groups on the two variables, and that the groups could be differentiated by the two variables. SEARS III was factor analyzed into a 2 component model in which deprivation and overstimulation were identified separately for nurses and patients. Because the factor structure was different for the two samples, a one component model (SEARS IV) of preceived environmental stress that combined the previous samples was used to test hypotheses involving both patients and nurses. Nurses scored higher than patients on SEARS IV. Patients and their assigned nurses had significantly different perceptions of environmental stress and STAI state anxiety. This study supports the theory by Lazarus that perception is the key to understanding differential stress to the same environment.
