Factors associated with the prescription of antidepressant (ATD) treatment versus no antidepressant (Case-vignette, French nationwide panel of general practitioners, weighted multivariate logistic model, N = 1097).

†Sample stratification variables were forced in the model even if they did not met the pHosmer-Lemeshow test: p = 0.51. 25 GPs excluded because of missing values.The following variables were not selected after the univariate regressions (p>0.15): type of practice, occasional practice of alternative medicine, personal history of consultation of a mental health specialist, score of perception of the utility of and satisfaction about GP-mental health specialist cooperation, GPs' opinions regarding their training and effectiveness in depression management and patient's SES, density of private-practice psychiatrists in each GPs' local area.The following variables were rejected by the backward process in the final multivariate model: CME on depression diagnosis and management, personal history of depression, participation in a formal mental health care network, and GPs' opinions regarding barriers to access to psychotherapy in their practice area.
