Not Applicable

Completed

• Conditions: Chronic Pain
• Interventions: Behavioral: Peer Coach Assignment

• Registration Number: NCT02380690
• Lead Sponsor: VA Office of Research and Development

Brief Summary

To maximize implementation potential of pain self-management in the VA, alternative delivery methods are needed to provide Veterans with education and support needed to self-manage their pain, without requiring additional resources from healthcare teams. A novel and promising approach is a peer coaching model, in which Veterans with chronic pain who are successfully managing their pain offer information, support, and mentorship to other Veterans with pain.

Detailed Description

The investigators' goal is to test the effectiveness of a peer coaching model among Veterans. The investigators are examining feasibility for implementation alongside effectiveness, to shorten the timeline to implementation.

Aim 1 (primary aim): To compare 6-month (primary endpoint) and 9-month (sustained effects) effects of peer-supported chronic pain self-management versus controls on overall pain (intensity and function).

Hypothesis 1: Veterans in the peer support arm will experience reduced overall pain compared to controls.

Aim 2 (secondary aim): To compare 6- and 9-month effects of peer-supported chronic pain self-management versus controls on self-efficacy, social support, pain coping, patient activation, health-related quality of life, and health service utilization.

Hypothesis 2: Veterans in the peer support arm will experience greater self-efficacy, social support, pain coping, patient activation, and health-related quality of life, and lower health service utilization, compared to controls.

Aim 3 (pre-implementation aim): To explore facilitators and barriers to implementation of peer support for chronic pain, intervention costs, and fidelity to the model.

Arm && Interventions

Group	Intervention	Description
Peer Coach Assignment	Peer Coach Assignment	Veteran participants will be assigned to a peer coach, who delivered self-management instruction one-on-one over a 6-month period.

Primary Outcome Measures

Name	Time	Method
Brief Pain Inventory (BPI) (Overall Pain Assessment)	9 months	The BPI was developed to assess the severity of pain and the impact of pain on daily functioning, and has been validated in primary care studies. (Range = 0-10, 0 = no pain, 10 = worst pain imaginable)

Secondary Outcome Measures

Name	Time	Method
Anxiety	9 months	GAD-7 (Range 0-21, higher numbers = higher anxiety)
Patient Activation	9 months	Patient Activation Measure (Range: 0-100, higher numbers = higher activation)
Perceived Social Support	9 months	Measures perceptions of social support.(Range: 12-84, higher numbers = higher perceptions of social support)
Self Efficacy	9 months	Adapted from the Arthritis Self Efficacy Scale (Range 0-10, higher numbers = higher self efficacy)
Depression	9 months	PHQ-8 (Range: 0-24, higher numbers = higher depression)
General Health Perceptions	9 months	SF-36 General Health Perceptions (Range: 0-100, higher numbers = higher health perceptions)
Pain Catastrophizing	9 months	Pain Catastrophizing Scale, a 13-item scale that assesses catastrophizing - a pain belief that has been found to be a strong predictor of poor treatment response. (Range: 0-52, higher numbers = higher catastrophizing)
