Availability bias in clinical formulation: the first idea that comes to mind

Area of Science:

• Psychology
• Clinical Psychology
• Decision Theory

Background:

• Clinical psychologists formulate cases to guide treatment.
• Availability bias, where readily available ideas influence decisions, may affect formulation.
• This study investigates theoretical orientation and referral suggestions as sources of bias.

Purpose of the Study:

• To test if theoretical orientation influences availability bias in clinical formulation.
• To examine if referral letter suggestions introduce availability bias.
• To assess if clinicians selectively recall information or neglect alternatives due to bias.

Main Methods:

• 44 qualified and 20 trainee clinical psychologists participated.
• Participants formulated a fictional client with attachment difficulties and PTSD based on a referral letter.
• Data collected included information recall, areas of interest, and initial hypotheses.

Main Results:

• No evidence of availability bias due to theoretical orientation was found.
• Attachment-oriented clinicians showed increased focus on attachment concepts.
• Theoretical orientation predicted focus but not biased information recall or framework neglect.
• The test for referral suggestion bias was inadequate due to a potential ceiling effect.

Conclusions:

• Theoretical orientation does not appear to introduce availability bias in clinical formulation.
• Attachment orientation influences focus but not necessarily biased information processing.
• Further research is needed to adequately test the impact of referral suggestions on formulation bias.
