This study aims to develop a scale for measuring the effectiveness of reality-based crime shows. The dearth of study reported in the literature in this domain, particularly with reality based-crime shows. Well established CAB (Cognitive Affective Behavioral) model is taken for benchmarking. Items are developed and classified under these three constructs – cognitive, affective, and behaviour. Under cognitive construct, general awareness and causal awareness are taken as subdomains; under affective construct, emotional coping and sympathetic feelings while under behavior construct responsible, preventive, maladaptive, and novel technique seeking behavior were taken into consideration. Using the proposed questionnaire following the cross-sectional design, data is collected from 400 respondents from metro cities. Confirmatory factor analysis and reliability tests are conducted using SPSS-21 and Amos-21. Data analysis is conducted for reliability, discriminant and convergent validity. The instrument's high reliability is reported as all subdomains and constructs achieved more than recommended threshold values of Cronbach's alpha and composite reliability. Results also confirmed the achievement of convergent and discriminant validity. This study is limited to the young population of metro cities. Better generalization can be achieved by extending this study to a diverse set of respondents regarding demography and socioeconomic profile. This can be extended for measuring other reality shows.
