A three-item scale measuring the thoroughness and depth with which a consumer processed information about alternatives during a preference decision. Items assess the comprehensiveness of option processing, carefulness of information review, and attentiveness to product features during choice. The scale captures the cognitive effort dimension of decision making — how deeply the consumer engaged with the decision rather than relying on heuristics or shortcuts.

Two reliability estimates: α = .86 (Experiment 1, n = 225 undergraduates) and α = .85 (Experiment 3, n = 117 undergraduates) — Rahinel et al. (2021). VALIDITY: Not discussed. Scale appears original to the authors. Administered as self-report after a choice task. Companion to the Decision Readiness scale (DCRD, ID 2064) from the same paper — both scales were administered together to capture distinct aspects of the decision experience.
