Background
Objective structured practical examination (OSPE) has proven a reliable assessment tool in many specialities. Therefore, we aimed to construct an OSPE tool that could assess the clinical facial anatomy knowledge of non‐surgical aesthetic practitioners in a simulated environment.
Approach
Ten subject matter experts identified the themes individually with significant experience in teaching non‐surgical aesthetic practitioners. A consensus is then reached following extensive discussion to determine the final themes. After blueprinting, 25 stations were created comprising a single best answer with a clinical vignette and either a dissected Cephalus or a high‐resolution picture of a dissected Cephalus or a skull and a full‐face photograph of a patient. Finally, concurrent and construct validity were assessed for individual questions. Twenty‐five novices and 25 experts participated in the OSPE pilot. Each cycle lasted 45 minutes (90 seconds per station; 25 clinical and five rest stations). Internal reliability was measured by Cronbach's alpha. In addition, the novices and experts group scores were compared, employing an independent t‐test.
Evaluation
The mean item difficulty of the 25 questions was 0.65. There was a significant difference in the scores for experts (M = 48.56, SD = 1.003), novices (M = 33.60, SD = 3.18) and conditions; t (48) = 22.38, p = 0.000. These results suggest the construct validity and confirm the robustness of the OSPE set‐up to accomplish the learning outcomes.
Implication
We successfully designed and validated OSPE as an assessment tool to examine non‐surgical aesthetic practitioners' clinical facial anatomy knowledge. We envisage using OSPE in our future programmes and encourage programme directors to integrate it into the postgraduate curriculum in non‐surgical aesthetics.
