Assignment task:
The purpose of this study was to evaluate the effect of the Foster Pain Intervention (FPI) on pain and morbility. Seventy women who were scheduled for a hysterectomy completed the preoperative self-efficacy scale. The first 35 women who met the criteria were assigned to the control group, and the next 35 were assigned to the intervention group. Both groups received routine preoperative information. Those in the intervention group also received the FPI information. On the first and second post-operative day the patient mobility and the Observer Mobility Scales were scored.
