Official title
Computational Dissociation of the Causes of Cognitive Rigidity in Depression
Overview
This study will provide data for evaluating the psychometric characteristics of the tests assessing cognitive flexibility, including their (1) internal consistency, (2) feasibility and tolerability, their (3) convergent and discriminant validity of cognitive and affective constructs such as those introduced to understand mental disorders, and (4) sensitivity (and correspondence) to individual differences. For these tests to be useful in studying clinical conditions, they must show adequate reliability, validity, and sensitivity in large samples of convenience.
Interventions
- Diagnostic test Computational dissociation of the causes of cognitive rigidity in depression
involves a single testing session with surveys and tasks relevant to the experiment involving behavioral tasks and self-report questions through an online crowd-sourcing platform
Primary outcome measures
- Relationship of cognitive rigidity to depressive symptoms [Time frame: 1 hour]
- Relationship between environmental volatility and cognitive rigidity [Time frame: 1 hour]
