A multi-modality and multi-dyad approach to measuring flexibility in psychotherapy

Area of Science:

• Psychology
• Psychotherapy Research
• Dynamical Systems Theory

Background:

• Psychological flexibility is key to psychopathology and psychotherapy.
• Current self-report measures for flexibility have limitations.
• A nonlinear dynamical systems framework offers a complex view of flexibility.

Purpose of the Study:

• To propose and validate a multimodal, multi-dyad approach to measuring psychological flexibility.
• To capture the complexity of flexibility beyond self-report limitations.
• To explore the utility of a nonlinear dynamical systems framework.

Main Methods:

• Developed a novel research paradigm involving a psychotherapy-like interaction.
• Collected multimodal data, including body movement and facial expressiveness.
• Utilized Hankel Alternative View of Koopmann analysis to reconstruct and compare behavioral attractors.

Main Results:

• Observed distinct behavioral patterns in case studies.
• Reconstructed attractors reflected differences in self-report measures and interaction behaviors.
• Demonstrated that single-modality data is insufficient for a comprehensive understanding.

Conclusions:

• A multimodal, multi-dyad approach is essential for accurately measuring psychological flexibility.
• This method addresses measurement issues in current psychological flexibility research.
• Findings support the proposed framework for capturing behavioral complexity in psychotherapy.
