The aim of this study is to assess the validity of Anxiety, Life Satisfaction and Social Media Addiction scales (TELSMAS). To achieve the purpose a cross-sectional survey design was adopted with a sample of 150. Rasch Measurement was adopted to validate the items. The instruments contained 56 items spread among the 3 constructs. The data collected was entered into Microsoft Excel 2016 and Winsteps for the Rasch Analysis. The scale was evaluated through content validity with experts, construct validity with Rasch infit and outfit statistics and Reliability. The results revealed that, the scale has substantial content validity with Kappa value of 0.86, and acceptable reliability values of 0.99 (Anxiety), 0.95 (life Satisfaction) and 0.96 (social media addition). Similarly, the scale satisfied the condition of unidimensional for the Rasch validation. However,14 items overall failed to satisfied the condition to be certified as valid and therefore completely deleted form the scale (5 in Anxiety and 9 in Social Media Scale). Thus, with the satisfaction of measurement requirements by 42 items, it can be concluded that, the developed TELSMAS validated in this study can be used to assess the level of anxiety, life-satisfaction and social-media addiction among school students and other vulnerable groups.
