Personal values and pain tolerance: does a values intervention add to acceptance?

Area of Science:

• Psychology
• Pain Management
• Behavioral Therapy

Background:

• Acceptance interventions show promise for pain coping, outperforming distraction and control techniques.
• Acceptance and Commitment Therapy (ACT) has demonstrated efficacy in improving pain tolerance and adjustment for chronic pain patients.
• The specific impact of the 'values' component within ACT interventions for pain has been underexplored.

Purpose of the Study:

• To compare the effectiveness of an ACT-based acceptance intervention with and without its values component.
• To evaluate the additive benefit of values clarification in acceptance interventions for pain management.
• To investigate the role of values in enhancing pain tolerance during an acute pain task.

Main Methods:

• A cold-pressor task was used to induce acute pain in participants.
• Participants were assigned to either an ACT-based acceptance intervention with values, acceptance alone, or a control condition.
• Pain tolerance, pain threshold, and pain severity ratings were measured across conditions.

Main Results:

• The ACT-based acceptance intervention including values resulted in significantly greater pain tolerance compared to acceptance alone.
• Both acceptance conditions (with and without values) demonstrated superior pain tolerance compared to the control group.
• No significant differences were found in pain threshold, though the control group reported lower pain severity.

Conclusions:

• The inclusion of a values component significantly enhances the effectiveness of acceptance-based interventions for pain.
• Values clarification plays a crucial role in improving pain tolerance within ACT frameworks.
• These findings support the integration of values exercises into clinical practice for individuals with chronic pain.
