Capturing process and outcome in complex rehabilitation interventions: A "Y-shaped" model.

Area of Science:

• Neuroscience
• Psychology
• Rehabilitation Medicine

Background:

• Acquired brain injury (ABI) involves complex biopsychosocial factors impacting recovery.
• Current rehabilitation approaches face challenges in evaluating complex, multi-intervention programs.
• There is a need for integrated models to guide ABI assessment and rehabilitation.

Purpose of the Study:

• To propose a theoretical model for understanding and evaluating change processes in ABI rehabilitation.
• To integrate findings on psychosocial adjustment, awareness, and well-being post-brain injury.
• To identify specific interventions and change mechanisms within a theoretical framework.

Main Methods:

• Development of the "Y-shaped" model, integrating psychosocial adjustment, awareness, and well-being.
• Focus on theoretical modeling to guide intervention development and evaluation.
• Emphasis on measuring theoretically grounded change processes in outcome studies.

Main Results:

• The "Y-shaped" model centralizes the concept of discrepant or threatened identity.
• Identifies specific interventions and interactions crucial for rehabilitation change.
• Highlights the importance of personal meaning in addition to functional outcomes.

Conclusions:

• Integrated models of change are essential for effective ABI rehabilitation.
• Outcome assessment should include the personal meaning of activity and social participation.
• The proposed model provides a framework for developing and evaluating theoretically grounded rehabilitation programs.
