TONIC IMMOBILITY SCALE: THE STUDY OF TURKISH VALIDITY AND RELIABILITY

Objective: The purpose of this research is to adapt the Tonic Immobility Scale (TIS) which have been already developed in United States, to Turkish culture.Material and Method: Exploratory Factor Analysis and Confirmatory Factor Analysis (CFA) was performed for the validity of the scale and also the Impact of Event Scale-Revised (IES-R) and Peritraumatic Dissociative Experiences Questionnaire (PDEQ) were used for criterion validity.Results: Cronbach Alpha value was used for the reliability method. As a result of the analysis of TIS, which has ten items and two sub-dimensions, x2/Sd, RMSEA, IFI, CFI, SRMR, PGFI and PNFI compliance indexes were found to be at a good level. Cronbach's alpha value of TIS is alpha=0.90. Cronbach's alpha values of tonic immobility and fear subscales are alpha= 0.87 and 0.80.Conclusion: It has been concluded that TIS is a suitable evaluation form in terms of validity and reliability and can be used to measure the freezing, immobility and unresponsiveness of individuals who have been exposed to trauma.
