Development and Validation of an Assessment Tool on Selfitis

The Selfitis screening scale was developed to understand the level of addiction and possible areas of disturbance among college students aged 18–25 and help plan for an intervention. The process of tool development involved 1, 080 samples under 3 phases namely item writing, Development of the Tool and Standardization. Based on review of literature and discussions carried over by 18–25 year old participants who were aware of selfie taking133 items were generated initially. Thus developed form was subjected to experts reviewing and item analysis. The items which had a very high or very low score on difficulty and very low on discrimination were removed. The resulted 81 item rating scale with 10 dimensions associated with Selfitis was named as S³ (Selfitis Screening Scale) and was subjected to reliability check, the Cronbach's Alpha was found to be 0.98 which shows high tool reliability. A Predictive validity was calculated using Between Groups't test among selfie takers and non takers and the t value for each item was ranging between 2.5 to 9.5 significant at 0.01 level of significance indicating very high predictive validity with regard to the research objectives.
