Mobilite Envanteri Türkçe Formunun Geçerlilik ve Güvenilirliği

Abstract

The Mobility Inventory (MI; Chambless et al. 1985) assesses the degree to which respondents avoid 26 typical agoraphobic situations, when alone and when accompanied. The aim of this study is to investigate the validity and reliability of Mobility Inventory-Turkish Version.Method: Mobility Inventory was administered to 92 patients (male=33, female=59) with agoraphobia or panic disorder with agoraphobia. Analysis were applied to "when alone" and "when accompanied" subscales. Reliability of MI was analyzed by test-retest correlation, split-half technique, Cronbach's alpha coefficient. Construct validity was evaluated by factor analysis performed with principal component analysis and varimax rotation after the Kaiser-Meyer-Olkin (KMO) and Bartlett test had been performed. Results: "when alone" subscale: Cronbach coefficient was found as 0.93. In analysis performed by split-half method reliability coefficients of inventory halves were found as 0.892 and 0.878. Again spearmen-brown coefficient was found as 0.879 by the same analysis. Factor analysis revealed six basic factors. These six factors explained 70.4 %of the total variance. "when accompanied" subscale: Cronbach coefficient was found as 0.906. In analysis performed by split-half method reliability coefficients of inventory halves were found as 0.865 and 0.850. Again Spearmen-Brown coefficient was found as 0.766 by the same analysis. Factor analysis revealed seven basic factors. These seven factors explained 73.4 %of the total variance. Conclusion: Analysis demostrated that ME-Turkish version had a satisfactory level of reliability and validity
