TL;DR: Results suggest that the PrSC scale confounds two unrelated, motivationally distinct dispositions--rumination and reflection--and that this confounding may account for the "self-absorption paradox" implicit in PrSC research findings: Higher PrSC scores are associated with more accurate and extensive self-knowledge yet higher levels of psychological distress.

TL;DR: The Self-concept Clarity Scale (SCC) as discussed by the authors measures the extent to which selfbeliefs are clearly and confidently defined, internally consistent, and stable, and is associated with high Neuroticism, low SE, low Conscientiousness, low Agreeableness, chronic self-analysis, low internal state awareness, and a ruminative form of self-focused attention.

TL;DR: The IASR-B5 as mentioned in this paper is an extension of the Revised Interpersonal Adjective Scales (IAS-R) to include the additional Big Five dimensions of conscientiousness, neuroticism, and openness to experience.

TL;DR: In two online studies as mentioned in this paper, respondents completed personality inventories and a survey of their Internet commenting styles, and strong positive associations emerged among online commenting frequency, trolling enjoyment and troll identity, pointing to a common construct underlying the measures.

TL;DR: An item-analytic procedure that identifies and selects items in terms of their estimated geometric location within a circumplex model is described and applied to the task of reducing the 128-item IAS to a 64-item short form version (IAS-R), found to have improved substantive and structural characteristics and acceptable reliability.
