Cost-utility and Physiological Effects of ACT and BATD in Patients With Chronic Pain and Depression

Summary

Objectives: (1) To analyze the effectiveness of adding a group-based form of Acceptance and Commitment Therapy (ACT) or a behavioural activation program for depression (TACD) to the treatment as usual (TAU) for patients diagnosed of chronic pain and comorbid mild-moderate major depression; (2) To examine the cost-utility of these psychological treatments from healthcare and societal perspectives; (3) To measure a set of biomarkers alongside the RCT in order to know the physiological underpinnings of these psychological therapies and to identify potential predictors of treatment response.

Methodology: 12-month multisite, randomised, controlled trial (RCT) Centres: Parc Sanitari Sant Joan de Déu (St. Boi de Llobregat) and Hospital del Mar (Barcelona).

Participants. 225 adult patients with chronic pain that meet the diagnostic criteria for mild-moderate major depression will be randomly assigned to one of the three study arms: TAU + ACT vs. TAU + TACD vs. TAU.

Primary outcome: Quality of life. Secondary outcomes: pain intensity, depression severity, anxiety symptoms, pain catastrophising, and pain acceptance. Costs to the healthcare system and to society and quality adjusted life years (QALYs). In addition, the empirically validated app Multicenter Pain Monitor® will be used to monitor participants alongside the treatments (ecological momentary assessment). Biomarkers: hair cortisol and cortisone, corticosteroid-binding globulin (CBG), ACTH and cortisol in plasma, and genotyping of 5 polymorphisms in the FKBP5 gene involved in the regulation of the hypothalamic-pituitary-adrenal axis activity, cytokines, Th1: IL-6, IL-8, TNF-α; cytokines Th2: IL-10 + hsCRP test, and vitamin D levels. Main statistical analyses: Intention-to-Treat analyses that will include all participants who undergo random allocation, using multiple imputation to replace missing values. Linear mixed-effects models will be performed using Restricted Maximum Likelihood to estimate the parameters. Calculation of between-groups effect sizes using Cohen's d and of the number-needed-to-treat. Economic evaluation: cost-utility ratios evaluated by applying bootstrapping techniques, acceptability curves, and sensitivity analyses.

Conditions

• Randomized Controlled Trial

Interventions

BEHAVIORAL

Acceptance and Commitment Therapy (ACT)

Group treatment protocol of 8 weekly 90 minute sessions. Session 1: Presentation of the general concept of ACT therapy. Session 2: Value analysis I. Session 3: Value analysis II. Session 4: Value analysis III. Session 5: Values and feelings. Session 6: Taking a direction. Session 7: Dare and change. Session 8: Ready to act with ACT.

BEHAVIORAL

Behavioral Activation Therapy for Depression (BATD)

Group treatment protocol of 8 weekly 90 minute sessions. Session 1: Collection of information regarding areas of activity and interaction contexts. Session 2: Identification of information related to depressive behaviours. Session 3 Obtaining complementary information regarding the characteristics of the history of patient interactions and any contexts. Session 4: Explanation of the hypotheses of problematic behaviour, its maintenance and change throughout the intervention. Session 5: Once the 10 target activities have been identified, a record is made to track and their progress weekly. Session 6: Discussion of what was obtained from the records in general and of the satisfaction obtained, and explanation of the contexts and reinforcers. Session 7: Psycho-education Session 8: New behaviours, the goals achieved and the maintenance of the weekly activity are inquired about.
