The migration of psychological assessment from laboratory to digital and online environments has fundamentally transformed the methodological landscape of media psychology research. This paper provides a comprehensive evaluation of digital psychometric methods used in online media research contexts, examining validity, reliability, and methodological standards for web-based psychological assessment of media audiences. Drawing on classical test theory, item response theory, and the rapidly evolving literature on digital assessment validity, the paper synthesizes evidence across four digital assessment modalities: self-report online surveys, behavioral task-based measures administered via web platforms, passive behavioral sensing, and hybrid approaches integrating multiple data streams. Key validity threats specific to online assessment contexts are examined including careless responding, motivated self-presentation, device heterogeneity, environmental distraction, and population selection biases in online convenience samples. The paper reviews meta-analytic evidence on online versus offline measurement equivalence across major psychological constructs including Big Five personality, working memory, reaction time-based attention measures, and clinical mental health scales. IRT-based approaches for detecting and managing careless responding in large-scale online media studies are proposed. The paper proposes a Digital Assessment Quality Framework (DAQF) specifying minimum standards for validity evidence, reliability estimation, equivalence testing, and transparency reporting in online media psychology research. Practical recommendations are provided for survey design, attention check protocols, sample size determination, and statistical correction procedures appropriate for web-based media research contexts.
