A qualitative investigation into the usefulness and impact of the performance intervention zone system used in the diagnostic assessment of internationally educated massage therapists

SummaryPurposePrevious work (Finch, 2008) reported on the development and implementation of a safety oriented system of performance intervention zones (PIZ), which was used in the assessment of internationally educated massage therapists. The study reported in this paper explores the usefulness and impact of the system as experienced by the evaluators involved in the diagnostic assessment.MethodThis exploratory research was of a qualitative design in which data were collected during a series of individual semi-structured interviews with evaluators who used the performance intervention zone system during the diagnostic assessment of internationally educated massage therapists in Ontario. After obtaining informed consent, interviews were taped, transcribed and analyzed, resulting in identification of a number of themes and recommendations regarding future use and development of the system.ResultsAnalysis revealed four themes within the data. These were that the performance intervention zone system 1) enhanced the confidence of examiners in their ability to conduct the comprehensive clinical examination effectively, 2) assisted and improved examiner decision making during the examination, 3) was a useful aid to communication regarding candidate performance, and 4) could be improved by clarifying the nature of intervention and implementing more extensive examiner training prior to the examination.ConclusionThe performance intervention zone system was found to be useful in orienting examiners to the evaluation process, in supporting decision making during the comprehensive clinical evaluation and as an aid to communication in the post-examination review of candidate performance. The system could be improved through implementation of a pre-examination workshop focused on use of the PIZ and by delineation of levels of examiner intervention during the examination.
