The study aims at the development of an adherence scale (APP) for psychoanalytic therapy (PA) and psychodynamic therapy (PD) with high discriminant ability to differentiate between these 2 treatments. The development of the APP scale comprises 6 steps. Nine trainees underwent an intensive rater training. After reaching an interrater reliability of ICC [2.1]>0.60, seven trainees participated as raters in the psychometric study. The reliability of the APP Scale was ICC [1.1]=0.58 and ICC [1.3]=0.81 (PA subscale), and ICC [1.1]=0.67 and ICC [1.3]=0.86 (PD subscale) indicating sufficient to excellent reliability. The discriminant ability of the APP Scale based on audiotaped PD- and PA-sessions was d=1.04 (PA subscale) and d=1.48 (PD subscale) indicating large effect sizes, respectively. Thus, the APP scale applied by trained psychology students and postgraduates, discriminates reliably the conceptually overlapping treatments, provided that the raters were trained intensively by experts in PA and PD.      «
