In the context of psychotherapy research, emotional processes or the emotional experience respectively are gaining increasing importance as process parameters in ongoing therapies. The relationship between emotional processes in therapy and the therapy success has proven to be a robust finding in process-outcome research (cf. Orlinsky et al., 2004), and especially the construct of the emotional processing plays a significant role here. Emotional processing describes an intra-psychic process which adds a cognitive component to the psychobiological components of the emotion in order that a mental phenomenon arises from an originally purely physical one (Lecours et al., 2007). On an overlapping methodological level, the emotional processing conceived in this way has proven to be a reliable predictor for the success of the therapy with humanistic methods, with behavioural therapy and with psychoanalytically-based methods (Goldman et al., 2005; Castonguay et al., 1996; Silberschatz & Curtis, 1993, among others). These findings are mainly related to short-term treatments, with the result that there has been a research gap to date in the investigation of emotional processing in long-term treatments.
The determination of a mediator presupposes differential outcome effects which have been verified in the Munich Psychotherapy Study (MPS) for the three methods approved in the applicable guidelines (cf. Huber et al. 2012a; Huber et al. 2012b; Huber et al. 2013). The investigation is to occur on the basis of Munich Psychotherapy Study (MPS) database.
In order to answer the research questions posed above, the process parameter of the emotional processing is set in relation to the outcome measured post 1- and 3-year catamneses over the measurement times. As this phase of the research should be concerned with the correlations of the therapy processes and the in lege artis concluded therapies and the long-term outcome, we are selecting a completer sample as the data basis. From the total of 100 patients in the intend-to-treat random sample, 85 have finished their therapy in a regular manner. Following an assessment of the recording quality of the hours in the mid phase, 13 cases (6 AP, 3 DP, 4 CBT) had to be excluded. The remaining 72 patients are to be screened as to whether they have two sessions of the mid phase which reach or exceed the lower operationalised cut-off value of the hours rating scale for change relevance. The number of therapies found in this way should be the same per therapy form and not exceed an n = 20:
1. Analytical psychotherapy (AP): 20 patients with two to three sessions per week lying down;
2. Depth psychology-based psychotherapy (DP): 20 patients with one session per week, in a sitting position;
3. Cognitive behavioural therapy (CBT): 20 patients with one session per week.
The degree of the emotional processing in the mid phase should be recorded with the Experiencing Scale (EXP; German version Dahlhoff & Bommert, 1978; Klein et al., 1986a; Klein et al., 1986b) which measures the emotional and cognitive participation of the patient in a therapeutic dialogue on a seven-stage scale. In order to apply the EXP scale, hourly segments are selected in a targeted manner from over the course of the therapy. Initially hours are selected from the mid therapy phase, operationalised as the mid third of the therapy. It is assumed with this therapy phase that it represents the genuine "working phase" of the therapy. Two therapy sessions are then selected from this phase on the basis of the so-called hours rating scale, from which it is to be expected theoretically that they are suitable for answering our problem ("significant events approach", Elliott, 2010).
Change relevant hours can be identified in the Munich Psychotherapy Study with the help of the hours rating scale, on which the therapist conducted an evaluation of the hours on a Likert scale immediately after the end of the hours. The change relevance is operationalised a) for the AP and DP as one hour in which the "transference processing" variable was scored on a 4-step Likert scale, with 4 = much, and the "hours evaluation" variance on a 5-stage Likert scale, with +1 or +2 (= "a good hour"), and b) for the KCBT as one hour in which the "recognisable cognitive restructuring" or "recognisable behavioural change" variables were scored, with 4 = much, and the "hours evaluation" variance on a 5-stage Likert scale, with +1 or +2 (= "a good hour").
"We know well that therapy works, i.e. is responsible for change, but have little knowledge of why or how it works" (Kazdin, 2007, page 2). In this way, Kazdin is pointing out the necessity of a process-outcome approach in which, through an understanding of the therapeutic processes, strategies can in turn be optimised which initiate the therapeutic change process. Thus the process-outcome approach is to be regarded as a central component of quality assurance and the optimising of psychotherapeutic treatments. In this research context, this study should contribute to findings about the effectiveness and the effective mechanisms of different forms of therapy with depressive patients.
