Start model Legenda: GD = Guideline Depression, AB = Assesment Behaviour. Model fit parameters: Chi-square 91.732, df = 73, p = 0.07; RMSEA = 0.036; SRMR = 0.067, CFI = 0.974. Straight lines indicate direct effects (beta matrix), double-arrowed dotted lines indicate associations in the disturbance terms (psi matrix); single arrowed dotted lines indicate direct effects which had to be included in the model to get positive definite matrices. All coefficients p < 0.05; except (*), p is not significant, at N = 200, artificially. Explained variance (R2) of endogenous variables: Attitude to the GD (0.10); Social Norm, influence of colleagues on acceptation of the GD (0.05); Social Norm, influence of important others in adherence to the GD (0.10); Self-efficacy the use of the GD (0.14); Knowledge and skills concerning the GD (0.10); Stimulus in the use of the GD due to the format of the guideline (0.05); Stimulus in the use of the GD due to the implementation of the guidelines (0.14); Stimulus in the use of the GD by the quality of the guideline (0.09); Intention to use the GD (0.24); Use of the GD (0.12); Change in assessment behaviour due to the GD (0.25).
