Abstract
Background: There is increasing demand of dermatologists and dermatological procedures these days and along with increased demand the assessment of dermatological surgical skills is now an important part of residency. Micro dermabrasion is nowadays a very common procedure used for multiple skin disorders Dermatologist should be properly train in this procedure. There is no tool available to assess the competencies of residents regarding Micro dermabrasion. We developed an assessment tool for assessing the skills in this procedure.
Methods: Tool is designed for the procedure of micro dermabrasion. It comprise of 26 items. The selected scale was juster scale. In order to ensure the construct validity of the tool it was looked whether it is able to assess the competence of a trainee in dermatology regarding the use of dermabrasion. The items were reviewed and further elaborated by content experts for content validity. For predictive validity it was looked into whether the tool has very high face validity and whether tool later predict the overall performance of the residents in dermatological procedures.
Cronbach’s α was applied to all items, those items which were increasing the errors were removed. For Inter rater reliability tool was assessed by multiple raters. We did multiple test retests to measure the validity and reliability.
Results: The tool has good face validity, appropriate construct validity. It has good internal consistency and inter rater reliability. The standardization of the tool was done by Angoff method,
Conclusions: There is no assessment tool available globally to assess the competency regarding micro dermabrasion. The problem should be fixed by budding a specific measurement scale which will enhance the reliability and validity of the procedure and also augment the competency of our future dermatologists.
