[Development of a questionnaire to assess the effective factors of communicative movement therapy: IP-Kom62 and IP-Kom22].

Abstract

The study aimed to develop a questionnaire that captures the key effectiveness factors of the Communicative Movement Therapy (KomBT) method.A group of experts developed five content-related scales in an explorative and deductive manner to map specific factors of the method's effectiveness. The Inventory for Process Assessment of Treatment with Communicative Movement Therapy (IP-Kom) contains 62 items and was completed by 211 patients after a KomBT therapy session. The data was analyzed using cluster and factor analysis to check the assignment of the items to the scales. In addition, an artificial neural network was used to validate the predictive power of the item statistics for the subjective benefit of the therapy.The cluster analysis confirmed a 5-factor solution, and the subsequent factor analysis confirmed the five factors of the questionnaire: positive body experience, cohesion, inhibition, positive development and emotionality, and positive experience of closeness. The reliability of the individual factors was between α=0,73 and α=0,93, which indicates a high level of internal consistency. Factor analysis was used to reduce the number of items from 62 to 22 (IP-Com22) and to clarify the content of the statements in the scales. Whether the KomBT procedure is experienced as helpful could not be attributed to one factor alone. The assessment only correlated with the sum of all factors surveyed in the IP-Kom22.The IP-Kom22 is an economical questionnaire for the assessment of group and body psychotherapeutic factors that can be used both in routine clinical practice and in further scientific studies.
