Positive self-view refers to the tendency to hold favorable beliefs and evaluations about oneself and to prioritize positive self-relevant information during information processing. Although various operationalizations of positive self-view (e.g., self-esteem, core self-evaluations, and optimistic self-beliefs) have been extensively studied, the relationships among different measurements remain insufficiently characterized. Here, we present a dataset designed to measure positive self-view through multiple instruments. The dataset includes item-level data from 12 self-report questionnaires and trial-level data from three behavioral tasks, collected from 771 adult participants (503 of them have valid data for all items). In total, these yield 161 measures of positive self-view, comprising 135 questionnaire items reflecting subjective self-evaluations and 26 behavioral indices capturing bias in self-related information processing. Moreover, the dataset included four scales to measure the psychological outcomes: depression, anxiety, subjective well-being, and procrastination, providing resources for investigating the role of positive self-view in psychological functioning. This dataset offers a comprehensive resource for investigating the construct of positive self-view and its associations with psychological outcomes.
