Study summary

The aims are to test feasibility and preliminary effects of a smart phone delivered ACT treatment for adults with longstanding pain.

The hypotheses are that

  1. ACTsmart will be a feasible and accessable treatment delivery form
  2. ACTsmart will improve function and quality of life
Read the detailed description

Chronic pain affects 12-30% of the population and often results in depression, disability, and reduced daily function and quality of life. Medical strategies are often ineffective or insufficient to alleviate symptoms and increase functioning. Instead, the empirical support for cognitive behavior therapy (CBT) is today well established, and such interventions are commonly seen as critically important for patients with chronic pain. However, modest effects sizes calls for further improvements. Recent developments within CBT, particularly Acceptance and Commitment Therapy (ACT), have suggested the utility of acceptance and mindfulness strategies to manage pain and distress. The body of evidence for ACT has grown rapidly during the past decade, and ACT is today listed by the American Psychological Association as a treatment for chronic pain, with strong empirical support.

Internet-delivered ACT Despite the increased empirical support for ACT the availability is still very limited, and a large number of patients do not receive this treatment. In other domains, the accessibility of empirically supported treatments has increased during the past decade due to the development of methods to deliver the treatment via internet. For example, a large number of studies illustrate the utility of internet-delivered CBT for anxiety, insomnia and depression, with treatment effects similar to those obtained in studies with face-to-face treatment. Few studies have yet evaluated internet-delivered ACT (iACT) for chronic pain, but a recent pilot study from our group with participants suffering from fibromyalgia (n=41) illustrated very promising results that warrant further studies to evaluate the effects of this treatment.

To make treatment more accessible and present in patients' daily life we will use a smart phone application to deliver treatment.

Recruitment Patients will be recruited through self referral. Information regarding the study will be provided through newspapers and social media, as well as in direct communication with pain clinics and primary care units, including instructions regarding e.g. eligibility and how to sign up. Once patients have been found eligible and expressed interest in study participation they will be assessed by a psychologist, and when needed by a pain physician, via semi-structured interviews to confirm eligibility and to ensure that the patient meet the study criteria. Informed consent is obtained from all participants prior to the assessment.

Statistical methods Evaluations of treatment effects are primarily based on intent-to-treat analyses. The statistical approach will primarily be based on linear multilevel modeling (LMM), which takes into account dependencies between repeated measures and differences between patients in pre-treatment status and treatment response (i.e. random effects modeling) and also provide means of handling missing data. More traditional methods, such as ANOVA and hierarchical regression, may also be utilized when appropriate.

Interviews Evaluations of feasibility and as a base for further development of the smart phone application will be done via semi structured interviews during and after treatment period.

Interventions

  • BehavioralACTsmart

    Participant receive ACT treatment via a smart phone application, including psychologist support via a message function within the application. Treatment content is divided into four modules: 1. education about pain behaviors, exposure and acceptance and commitment therapy 2. education about pain physiology 3. exercises on changing behaviors, acceptance, mindfulness, defusion and exposure 4. value based exposure in the participant's daily life

What researchers measure

Primary outcomes

  1. Pain Interference Index (changes between assessments)

    Self rated measure of daily functioning related to pain

    Time frame: Baseline, 8 weekly ratings, post (8 weeks), follow ups three, six and twelve months post treatment

Secondary outcomes

  1. Psychological Inflexibility in Pain Scale (changes)

    Self rated psychological inflexibility related to pain. Total score min 12, max 84, lower values are interpreted as higher psychological flexibility, higher values interpreted as lower psychological flexibility. Two subscales; fusion (4-28) and avoidance (8-56) are summed to compute a total score.

    Time frame: Baseline, 8 weekly ratings, post (8 weeks), follow ups three, six and twelve months post treatment

  2. Valuing Questionnaire (changes)

    Self rated progress and obstacles in valued actions. The Valuing Questionnaire consists of two subscales: progress (0-30) och obstacles (0-30). No total score is computed. On the obstacle subscale higher scores are worse, and on the progress subscale higher scores are better.

    Time frame: Baseline, 8 weekly ratings, post (8 weeks), follow ups three, six and twelve months post treatment

  3. Patient Health Questionnaire 9 (changes)

    Self rated depressive symptoms. Score is summed to a possible range of 0 to 27. Higher scores are interpreted as worse.

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  4. European Quality of Life Five Dimensions Questionnaire (changes)

    Self rated quality of life. Scores are calculated to a number between 0 and 1, where 0 in theory is equal to death, and 1 is considered equal to perfect quality of life.

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  5. Insomnia Severity Index (changes)

    Self rated degree of insomnia

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  6. Pain intensity (changes)

    Self rated degree of pain during last week on a scale from 0-10

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  7. Occupational status (changes)

    Self reported occupational status indicated on a pre specified list, including sick leave and/or sick retirement

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  8. Generalized Anxiety Disorder - 7 (changes)

    Self rated symptoms of anxiety

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment

  9. Medication use (changes)

    Self reported medicine use

    Time frame: Baseline, post (8 weeks), follow ups three, six and twelve months post treatment
