Development of an occupational internal driving force scale for general practitioners receiving residency training and assessment of its reliability and validity / 中华医学教育探索杂志

ABSTRACT

Objective:To develop an occupational internal driving force measurement scale for general practitioners receiving residency training, and to investigate its reliability and validity.Methods:A pool of items was constructed for the scale based on the literature analysis and qualitative interview results of occupational internal driving force and the current development status of general practitioners, and then expert Delphi consultation was conducted to form the initial version of the scale. A questionnaire survey was conducted among 403 general practitioners to test the reliability and validity of the scale.Results:There were 11 items in the occupational internal driving force scale for general practitioners receiving residency training, which were divided into three dimensions. The scale had a Cronbach's α coefficient of 0.945, and each dimension had a Cronbach's α coefficient of above 0.850; the KMO coefficient of the Bartlett's sphericity test was 0.925. The factor analysis showed that all items had a factor load of ≥0.4 and a commonality of >0.2, and thus 11 items were retained. Three common factors were extracted by the factor analysis and the correlation analysis showed a correlation coefficient of >0 between the common factors of the total score of the scale and a significant positive correlation ( P<0.01). Based on the contents, theoretical research, and expert suggestions of each factor, they were named subject affiliation, development expectations, and identification needs, which contained 3 items, 3 items, and 5 items, respectively. Conclusions:The occupational internal driving force scale for general practitioners receiving residency training has a reasonable structure and good reliability and validity and is suitable for evaluating the occupational internal driving force of general practitioners, which provides guidance for the vocational education of residents.
