Methodological concerns in evaluating psychiatric nursing care modalities and a proposed standard group protocol format for nurse-led groups.
The importance of detailing therapeutic effort and its outcome cannot be underestimated. The need to document outcomes has been re-emphasized in recent psychiatric mental health literature; however, the methodology for addressing threats to validity is well established. This article identifies the problems and issues related to a systematic evaluation of a therapeutic group intervention in an inpatient setting, specifically threats to validity, and describes the processes used in planning and implementing a standard group protocol format. The findings of this project depicting problems in the clarity and precision of documenting nursing practice are believed to be typical and generalizable. However, problems related to clarity and precision have not been addressed in the nursing literature. For a number of reasons, nursing staff members have not been sensitized to the importance of describing their practices in sufficient detail to allow others to replicate these practices. And yet, adequate evaluations of nursing efforts, particularly programmatic initiatives, require systematic testing with repeated trials. Although no description can describe in absolute terms what occurred, clear and precise descriptions of an intervention provide the foundation for valid conclusions about the effort. A detailed standard group protocol format provides a basis for establishing internal validity in subsequent quasi-experimental research designs as well as program evaluation studies.
