“…In a literature review the authors found six standardised coding systems to analyze the clients' perspectives. These six systems can be grouped in three categories: transversal systems, whose categories can be found in most therapeutic modalities (Therapeutic Impacts Content Analysis System -TICAS -Elliott et al, 1985;Booth et al, 1997; Integrative corrective experiences coding system; Friedlander et al, 2011; Good moments in counselling and psychotherapy; Mahrer & Nadler, 1986;Jones, Wynne, & Watson, 1986); systems that are adapted to certain theories, where categories refer exclusively to a certain type of therapy (Helpful Aspects of Experiential Therapy Content Analysis System -HAETCAS -Castonguay et al, 2010; Coding system for helpful and hindering aspects of CBT and IPT; Gershefski, Arnkoff, Glass, & Elkin,1996;Levy, Glass, Arnkoff, Gershefski, & Elkin;; and systems that refer to specific therapeutic phenomena, whereby the categories refer to phenomena that occur during the treatment (Empowerment Events System Timulak & Lietaer, 2001;Timulak, 2003). None of the systems mentioned above was considered appropriate to Morenian Psychodrama (MP), which lead us to develop the Helpful Aspects of Psychodrama Content Analysis System (HAMPCAS).…”
