WHAT THE TEST MEASURES
About This Assessment
Belief in Freedom/Determinism, FAD-Plus Test

Free Will and Determinism Plus Scale (FAD-Plus) Test - Symptoms and Signs

subjectivity
beliefs

This instrument assesses individual differences in beliefs about human agency and causal determinism. The Free Will and Determinism Plus Scale (FAD-Plus) uses self-report ratings to characterize how strongly a respondent endorses concepts related to free will, determinism, and related attitudes. It is commonly used in research settings and may also inform clinical case formulation when beliefs about personal control and responsibility are relevant.

The measure consists of 27 items and typically requires about 5 minutes to complete. It yields a profile of belief endorsements rather than a single global construct, supporting interpretation of nuanced or mixed viewpoints. The Free Will and Determinism Plus Scale (FAD-Plus) is often administered alongside other measures of motivation, attribution, and moral cognition to contextualize responses (Vohs).
