Measuring Cognitive Biases and Limitations: A Deep Dive into the DACOBS (Davos Assessment of Cognitive Biases Scale) Part 1
"We do not see things as they are, we see them as we are." Our brains are wired with shortcuts—heuristics—that help us make quick decisions. But what happens when those shortcuts become "bugs" in our mental software?
In this video, we explore the Davos Assessment of Cognitive Biases Scale (DACOBS), a ground-breaking 42-item tool designed to map the cognitive distortions that underlie mental health conditions, particularly psychosis and schizophrenia spectrum disorders.
๐ What is the DACOBS?
Developed by Mark van der Gaag and colleagues, the DACOBS represents the "cognitive turn" in psychosis research. Instead of focusing merely on the content of a delusion (what the person believes), the DACOBS measures the process (how the person processes information). It assesses 7 specific phenomenon that contribute to the formation and maintenance of delusional beliefs.
๐ The 7 Phenomenon Measured
We take a deep dive into the seven subscales:
- Jumping to Conclusions (JTC): Making major decisions with little evidence.
- Belief Inflexibility: The inability to update opinions when faced with new facts.
- Attention for Threat: A hyper-vigilance towards danger.
- External Attribution: Consistently blaming outside forces or people.
- Social Cognition Problems: Difficulty understanding social cues/intentions.
- Subjective Cognitive Problems: The internal sense of "foggy" thinking.
- Safety Behaviors: Actions taken to avoid anxiety that actually reinforce it.
๐ก Why is this important?
For individuals, this helps develop an understanding of their own behaviours and biases showing the way for self-improvement.
For learners and clinicians - especially those practicing CBT for Psychosis (CBTp), the DACOBS is essential for formulation. It moves the conversation away from "madness" and toward "thinking styles." It helps patients understand that their distressing beliefs are often the result of specific, identifiable processing errors—errors that can be corrected.
