The Influence of Mindfulness Based Intervention on Pain Perception in Chronic Pain Patients

28 giugno 2015 aggiornato da: Meir Medical Center

The Influence of Mindfulness Based Intervention on Pain Perception in Chronic Pain Patients Evaluating Personal Characteristics and Possible Mechanism

Background: Chronic pain is a common condition in the general population, causing great suffering in both physical and mental aspects. Previous research shows that mindfulness based interventions help chronic pain patients to cope better with their pain, and improve their quality of life. Although evidence support the efficacy of mindfulness based interventions for chronic pain, it is still unclear whether this efficacy involves a direct influence on sensory aspects of pain perception. Further more, the mechanisms of change responsible for the improved life quality and the possible moderating factors that may influence treatment efficacy, are still unknown.

Aim: The purpose of this study is to evaluate the efficacy of mindfulness based intervention on pain perception and quality of life in individuals suffering from chronic pain. The investigators will also evaluate potential mechanisms responsible for the change following mindfulness practice. Finally the investigators will examine the role of personal characteristics as potential moderating factors of mindfulness effect.

Hypothesis: The investigators hypothesize that 1) compared to a waitlist control group, chronic pain patients participating in a full mindfulness based program will report greater improvements in a) pain severity, b) quality of life and psychological symptoms, and c) will demonstrate changes in physiological characteristics of pain. 2) Changes following the mindfulness based program will be mediated by change in pain catastrophizing, self regulation capacity and pain acceptance. 3) The investigators hypothesize that gender, baseline mindfulness, and anxiety sensitivity will moderate the efficacy of the mindfulness based program.

Method: A randomized controlled design will be used to evaluate the efficacy of mindfulness based intervention on pain perception and quality of life in individuals suffering from chronic recurrent low back pain and osteoarthritis. Participants will be randomized to a mindfulness based treatment group, or to a waitlist control group, and will be assessed for psychological variables and psychophysical pain assessment before treatment. Participants allocated to treatment group will then attend six group meetings in which they will learn and practice different mindfulness meditation techniques, and will be asked to practice these techniques on a daily basis. Post treatment assessments will take place at the end of the intervention for both treatment and control groups.

  • Assegnazione: Randomizzato
  • Modello interventistico: Assegnazione parallela
  • Mascheramento: Separare

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Intervention group
The intervention group will participate in the Mindfulness Program consists of one 2-hour session each week for 6 consecutive weeks plus a half day retreat near the end of the intervention.
Comportamentale: mindfulness group meetings with psychologist
The Mindfulness Program consists of one 2-hour session each week for 6 consecutive weeks plus a half day retreat near the end of the intervention. Participants will attend weekly group meetings (15-20 individuals per group) in which they will be guided through a progressive experiential exploration of mindfulness. Participants will be asked to develop a daily meditation practice of 30-45 minutes with audio-recordings for guidance, and will report the amount and type of practice in a daily dairy. . A psychologist with rich personal experience in mindfulness who is trained in mindfulness based therapy will be responsible for administering the program.
Nessun intervento: Control group
Participants in the control group will be assigned to a waiting list group. Participants will be told that they will be eligible for the intervention three months after the completion of a preliminary documentation of their symptoms and additional measures. Participants will complete the same battery of measures according to the same time table as participants in the intervention group.
