This paper presents the development and standardization of a 40-item Likert-type Perception Measurement Scale tailored for Indian media professionals to evaluate their perceptions of White-Collar Crimes (WCCs) and Traditional Crimes (TCs). Grounded in sound conceptual and theoretical frameworks such as agenda-setting theory, framing theory, and ethical responsibility paradigms, the scale captures constructs including media coverage, ethical responsibilities, public awareness, factchecking practices, narrative framing, and challenges in reporting. These constructs were systematically derived to address key dimensions of media professionals' roles in shaping public discourse and accountability. By utilizing data from 980 media professionals across five states—Uttar Pradesh (263), Bihar (272), Maharashtra (156), Kerala (198), and Delhi (91); attempts were made for ensuring scale development process to witness meticulous item generation, pilot testing with 192 participants, and final testing, ensuring content depth and representativeness. The scale demonstrated robust psychometric properties, with high internal consistency (Cronbach’s Alpha = 0.91) and strong construct validity (average factor loadings > 0.65). Concurrent validity was established by comparing the scale's scores with existing ethical responsibility benchmarks, yielding a correlation coefficient of 0.78 (p < 0.01). Norms were developed using percentile-based ranges for low, moderate, and high perceptions, facilitating meaningful interpretation. The findings highlight significant regional disparities, offering insights into socio-political and cultural factors influencing media practices. Recommendations include targeted ethical training and region-specific public awareness initiatives to enhance the accountability and integrity of Indian media.
