Psychometric Characteristics of a Scale for Assessing the Effectiveness of Group Inpatient Psychotherapy with Psychotic Patients

The purpose of this report is to propose a self-assessment method complementing the assessment of psychotherapist. The scale developed allows retrospective assessment of psychotic patients themselves for the level of safety, security and adopted support from the therapist and the group. This development presents the psychometric data from an authorized scale for assessing the effectiveness of group psychotherapy. This development presents the psychometric data from a developed author scale to assess the effectiveness of group psychotherapy. The person who takes part in the research are N= 104 ? (84 man ? 21 women). The sample consists of persons aged between 19 and 76. To check the reliability analysis, a Cronbach alpha factor was used, the overall reliability of the scale was Cronbach's Alpha ? = 0 .826. To verify the constructive validity, a research factor analysis was carried out, the results obtained showed that Bartlett's spherical test was statistically significant (?less than 0.001), the adequacy measure (The Kaiser-Meyer-Olkin-Measure of Sampling Adequacy) for the scale is 0.787. The results show that there is only one factor that includes the issues under consideration, which mainly measures the created sense of trust and safety in psychotically ill patients. The results obtained show that the applied methodology for measuring effectiveness from group inpatient psychotherapy is satisfactorily reliable and constructively valid for the given sample of psychotically ill patients.
