Lest taxonomy become taxidermy: a comment on the relapse replication and extension project

Area of Science:

• Psychology
• Addiction Research

Background:

• The Relapse Replication and Extension Project utilized pretreatment relapse as a predictor for post-treatment relapse.
• This commentary critically examines the methodology and conceptualization of relapse in addiction research.

Purpose of the Study:

• To question the validity of using retrospective baseline relapse data as a predictor of future relapse.
• To differentiate between distal trait predictors and proximal state predictors in relapse prevention.
• To explore alternative perspectives on understanding and preventing relapse.

Main Methods:

• Commentary and critical analysis of existing research methodologies.
• Discussion of conceptual errors in evaluating relapse prediction (e.g., "taxidermy" error).
• Illustration of concepts through a case study and exploration of metaphors.

Main Results:

• Retrospective accounts of pretreatment drinking may not accurately represent true relapse episodes.
• Using static, distal baseline data may overlook dynamic, proximal factors influencing relapse.
• A systems approach, like viewing relapse as "falling off the wagon," offers a different perspective.

Conclusions:

• The reliability and validity of using pretreatment relapse as a sole predictor are questionable.
• Relapse prevention therapy may benefit from focusing on proximal state predictors rather than distal trait predictors.
• Understanding relapse as a dynamic process is crucial for effective intervention.
