Adoption and standardization of attitude scale for polio framed on oversees population from underdeveloped area of West Bengal

Background Study revealed fear from polio vaccination programme yet not completely has eradicated from the minds of immigrated communities resides in backward areas of Bengal. Due that, pre-established attitude tool was adopted for the formation of new tool for targeted population.

Methods Interestingly, attitude tool found almost similar result after 5 years of its first administration (on minorities). Foundation of tool was set on 3-point Likert type scaling style. Classical test theory (CTT) was followed in which popularity index and discrimination index were taken for item-analysis for pilot study.

Results CTT rejects 6 items and test-retest reliability with high r value 0.94 suggests the tool has excellent reliability. Standardized tool finally comes in 31 items with 9 different dimensions.

Conclusions CTT method as handy method for small sample item-analysis where popularity index and discrimination index used to refine values on which item-total correlation was administered on Pearson’s correlation at 99% confidence interval. Application of the same tool after some years in CTT method in constructing attitude tool have successfully applied.
