Establishment of a Scale to Measure Migration Proneness of Tribespeople

The aim of this study is to develop a scale to measure migration proneness of tribespeople. This study was designed as a quantitative survey research. A total 30 items were generated for measuring migration proneness Likert’s summated rating method was followed in the study for scale construction. The relevancy of the items generated was established by judges rating. The scores for each items were summated over all the respondents and relevancy index was calculated. The indices used for the selection of items in the study were an Index of discrimination (t-test), suggested by Edwards (1957) and Item score- total score correlation (Pearson’s r), suggested by Anastasi (1961) and Guliford (1971). The statements with high t values, greater than 2.228 and r value greater than 0.4 were selected. Thus 12 statements were selected for the final scale. Split half reliability was used in the present study using odd even method. The correlation co-efficient (r = 0.732) for the half test was obtained. The reliability of the full test was found to be 0.845, which indicates the appreciable reliability of the scale. Care was taken to include items covering the universe of content with respect to the different dimensions of migration proneness in the scale, thereby satisfying the content validity criterion.
