Abstract

Acceptance and Commitment Therapy (ACT) is an effective intervention for the treatment of chronic pain. Internet-based pain interventions might be an effective and cost-effective way to overcome treatment barriers of traditional face-to-face pain interventions such as the lack of availability and accessibility. However, little is known about the general (cost-)effectiveness of internet-based pain interventions and the specific (cost-) effectiveness of guided and unguided pain interventions. Therefore, the aim of this study is to investigate the effectiveness and cost-effectiveness of a guided and unguided ACT-based online intervention for persons with chronic pain (ACTonPain). ACTonPain is a pragmatic three-armed randomised controlled trial comparing ACTonPain with or without therapist guidance against a waitlist control group. Both active conditions differ only with regard to guidance provided by an eCoach, who sends feedback after each module. This study aims to include 300 participants. Randomisation and allocation will be performed using permuted block randomisation with variable block sizes. The intervention contains seven ACT-based modules with interactive exercises, and audio and video clips. Furthermore, the participants have the opportunity to receive daily text messages. Online self-assessments will take place at pre- and post-treatment, as well as at 6 month follow-up. The primary outcome is pain interference. Secondary outcomes include physical and emotional functioning, pain intensity, ACT-related variables as well as health-related quality of life. Moreover, a cost-effectiveness analysis will be conducted from a societal perspective. Demographic and medical variables will be assessed on the basis of self-reports in order to detect potential moderators or mediators of the effects. The data will be analysed on an intention-to-treat basis and also using per-protocol analyses. This study will contribute to the evidence base of internet-based pain interventions and provide valuable information about the treatment success and cost-effectiveness regarding the intervention's level of guidance (self-help only vs. guided self-help). If ACTonPain is shown to be effective, investigations in different healthcare settings should follow, to examine possible ways of implementing ACTonPain into existing healthcare systems. The implementation of ACTonPain could help to shorten waiting times, expand access to pain treatment and, potentially, also reduce treatment costs.

  • Online interventions are effective even in one-session and self-help format.

    “Although online interventions have demonstrated to be effective even in one-session and in a self-help format”

    From Online ACT intervention for fibromyalgia: An exploratory study of feasibility and preliminary effectiveness with smartphone-delivered experiential sampling assessment (2022) · cites this paper as Lin et al., 2015

    The Introduction reports evidence that internet-based interventions for chronic pain can be effective, but says only that unguided interventions may produce clinically significant effects; it does not establish effectiveness in a self-help format. The Intervention content section describes a seven-module programme completed over several weeks, not a one-session intervention. No passage found supports the one-session part of the claim (searched: “one-session self-help” and “single session”). Page numbers were not available in our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The effectiveness of online interventions appears to increase with a minimum of sessions and in a guided format.

    “their effectiveness appears to increase with a minimum of sessions and in a guided format (Lin et al., 2015; Vowles et al., 2020).”

    From Online ACT intervention for fibromyalgia: An exploratory study of feasibility and preliminary effectiveness with smartphone-delivered experiential sampling assessment (2022) · cites this paper as Lin et al., 2015

    The Introduction (page not provided) says internet interventions with at least some guidance are often more effective than unguided ones. The intervention-content and statistical-analysis sections describe weekly modules and a planned analysis of participants completing at least five of seven modules, but do not establish that effectiveness increases with a minimum number of sessions. This is a study protocol, not a report of that result. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
