Illustrating novel techniques for analyzing single-case experiments: Effects of pre-session mindfulness practice

Area of Science:

• Psychology
• Psychotherapy Research
• Mindfulness Interventions

Background:

• Evaluating intervention effectiveness in single-case experiments requires robust visual and nonparametric techniques.
• Novice therapists may benefit from strategies to enhance focus and empathic responding.
• Mindfulness practice is increasingly explored for its potential therapeutic benefits.

Purpose of the Study:

• To assess the effectiveness of brief mindfulness practice on therapist focus and client-therapist interactions.
• To investigate individual differences in response to mindfulness interventions in a novice therapist sample.
• To illustrate visual and nonparametric methods for analyzing single-case experimental data.

Main Methods:

• Employed an alternating treatments design across two novice therapists (one male, one female).
• Therapists engaged in either a 3-minute guided mindfulness practice or a control activity before 10 therapy sessions.
• Collected client-rated empathy, client- and therapist-rated real relationship, and therapist-rated self-awareness data.

Main Results:

• Dyad 1: Clients rated therapists as more empathic post-mindfulness; therapists reported less self-awareness hindrance and better relationships (moderate to strong effects).
• Dyad 2: Mindfulness practice showed moderate to strong effects on the real relationship, but not on empathy or self-awareness.
• Cross-case analysis revealed individual variability in response to the mindfulness intervention.

Conclusions:

• Brief mindfulness practice can enhance therapeutic effectiveness, particularly client-perceived empathy and therapist self-awareness, though effects vary individually.
• Single-case experimental designs with self-report measures are valuable for understanding personalized treatment responses.
• Further research with replicated single-case designs can elucidate nuanced effects of mindfulness in psychotherapy.
