Adapting of Inviting/Disinviting Index into Turkish

Abstract

The aim of the present study was to examine adaptability of Inviting/Disinviting Index with 10 items in two factors into Turkish. For the specified purpose, the instrument was first, translated into Turkish, then 3 separate pilot studies were conducted. In the first pilot study, based on confirmatory factor analysis (CFA) and reliability analyses, two items were identified as candidates for item deletion. In the second pilot study, due to validity concerns, exploratory factor analysis (EFA) was conducted to determine whether alternative factor structures exist in the presence of these two items. The EFA provided evidence for two-factor structure with 10 items. Finally, in the third pilot study, CFA supported two-factor structure of Turkish version of the IDI. Mean interitem correlations were deemed acceptable. In addition, one of the items was found to be non-invariant across gender. The two-factor IDI was found to be invariant across gender permitting the loading of this item to vary. Regression analysis indicated that factors of the IDI were positive predictors of students’ self-efficacy as measured by Motivated Strategies for Learning Questionnaire.
