Claim 1 of 5OverstatedIn a pilot study of 32 Swedish children and adolescents with conditions such as IBS or recurrent abdominal pain, 40% reported a clinically meaningful improvement after about 15 minutes a day for 12 weeks.View evidenceHide evidence

As stated40%

Why this verdict

The profile supports a pilot/feasibility study with 32 enrolled children/adolescents and a 12-week online audio-based hypnotherapy program, and it supports that 40% achieved clinically significant gastrointestinal symptom improvement. However, the abstract-level profile specifies that this 40% was among completers, with 25 of 32 completing and providing post-treatment data. Framing the result as simply 'in a study of 32' without the completer denominator can overstate the responder finding. The stated 15-minutes-per-day detail is also not verifiable from the supplied abstract-level profile.

Claim 2 of 5Not coveredStomach pain and other gastrointestinal complaints are common among children and adolescents, and recurring symptoms may be due to disorders of gut-brain interaction such as IBS or recurrent abdominal pain.View evidenceHide evidence

Why this verdict

The abstract-level profile supports that the study population consisted of children/adolescents with disorders of gut-brain interaction, including IBS, functional abdominal pain, and functional dyspepsia. However, it does not verify the broader background assertion that stomach pain and gastrointestinal complaints are common among children/adolescents. At abstract depth, that prevalence/context claim is not established.

Claim 3 of 5Not coveredPsychological treatments such as CBT and gut-directed hypnotherapy have shown the best results for these conditions, according to the clinician quoted in the story.View evidenceHide evidence

Why this verdict

The profile notes background language that gut-directed hypnotherapy is effective for children with DGBI, but it does not substantiate the broader comparative claim that psychological treatments such as CBT and gut-directed hypnotherapy have shown the 'best' results. CBT and a comparative ranking of treatments are not evidenced in the supplied abstract-level profile.

Claim 4 of 5Not coveredThe researchers say the study lacked a control group and should be interpreted cautiously, but they consider the method promising enough to justify further research; a larger PIPPI project is comparing hypnosis with CBT in 300 randomly assigned participants.View evidenceHide evidence

As stated300 participants

Why this verdict

The profile supports that the study was uncontrolled, that causal interpretation is limited, and that the authors concluded a randomized controlled trial is warranted to confirm efficacy. But the specific claim that an ongoing PIPPI project is comparing hypnosis with CBT in 300 randomly assigned participants is not present in the supplied abstract-level profile, so that portion is not verifiable at this depth.

Claim 5 of 5SupportedOne approach being investigated is hypnosis, delivered through relaxation exercises and guided imagery in audio recordings that children listen to at home.View evidenceHide evidence

Why this verdict

The paper profile supports that the investigated approach was a 12-week online/audio-based gut-directed hypnotherapy program for children and adolescents with DGBI. The profile specifically mentions audio files and online delivery. The relaxation/guided-imagery description is more detailed than the abstract-level profile, but the core claim that audio-based hypnosis was being investigated is supported.

Then look for missing context

Context layer

What the story left out

Important study details the story did not include.

  • The study enrolled 32 patients, but only 25 of 32, or 78%, completed the program and provided post-treatment data.

    The story mentions the 32-person pilot sample but, based on the supplied presentation, does not report the 25-completer denominator or the 22% attrition. This matters because the 40% clinically significant improvement was reported among completers.

    From Uncontrolled within-group feasibility study; Uncontrolled within-group feasibility study

  • Clinically significant gastrointestinal symptom improvement, defined as greater than 30% improvement, was achieved by 40% of completers, not necessarily 40% of all enrolled participants.

    The story reports the 40% improvement figure, but the presentation does not preserve the important completer-only denominator. That omission can change interpretation of the magnitude.

    From Uncontrolled within-group feasibility study

  • Pain intensity decreased only modestly, with small within-group effect sizes in child and parent reports.

    The story frames the topic around stomach pain and gastrointestinal complaints, but the supplied presentation does not reflect the paper’s nuance that pain-intensity changes were small compared with the broader gastrointestinal symptom-score improvements.

    From Uncontrolled within-group feasibility study; Uncontrolled within-group feasibility study

  • Outcome assessment relied on patient- and parent-reported measures, which introduces potential reporting/perception bias.

    The presentation says participants reported improvement but does not identify patient-/parent-reported outcomes as a methodological limitation. This is a material limitation in an unblinded, uncontrolled intervention study.

    From Uncontrolled within-group feasibility study

5 things the story did carry across
  • The paper’s primary design was an uncontrolled, single-arm within-group feasibility/acceptability study of a Swedish adaptation of online, audio-based gut-directed hypnotherapy.
  • Participants were children/adolescents aged 8–17 with Rome IV disorders of gut-brain interaction, including IBS, functional abdominal pain, and functional dyspepsia.
  • The intervention was a 12-week online program using translated/adapted audio files from a validated Dutch gut-directed hypnotherapy protocol.
  • The study found within-group improvements in PedsQL gastrointestinal symptom scores, with child-report d = 0.63 and parent-report d = 0.81, but the design cannot separate treatment effects from placebo effects, regression to the mean, or natural history.
  • The authors concluded that a randomized controlled trial is warranted to confirm efficacy and identify predictors of response.

1Lead resulthuman in vivoEvaluate feasibility/acceptability of a Swedish adaptation of an audio-based gut-directed hypnotherapy self-exercise program delivered online to children/adolescents with disorders of gut–brain interaction.Uncontrolled within-group feasibility studyExpand

In plain English

Uncontrolled within-group feasibility study of a 12-week, online, audio-based Swedish adaptation of gut-directed hypnotherapy for children/adolescents (8–17 years) with disorders of gut–brain interaction (IBS, functional abdominal pain, functional dyspepsia, Rome IV). Primary feasibility outcomes were program completion and acceptability/credibility; primary clinical outcome was gastrointestinal symptoms (PedsQL Gastro Short Scale).

Key findings

  • Program completion and post-treatment data: 25 of 32 enrolled patients (78%) completed the 12-week program and provided post-treatment data.
  • Significant within-group improvements in gastrointestinal symptoms on the PedsQL Gastrointestinal Symptoms Short Scale.Child-report d = 0.63; Parent-report d = 0.81
“DESIGN: Uncontrolled within-group feasibility study.”
What this piece can’t prove
  • Uncontrolled single-arm within-group design (no comparator) — limits causal inference.
  • Small sample size (32 enrolled; 25 completers) reported in abstract.
  • Attrition: 7 of 32 participants did not provide post-treatment data (22% lost to follow-up).

In plain English

Uncontrolled within-group feasibility study of a 12-week online audio-based gut-directed hypnotherapy program (Swedish adaptation of a validated Dutch protocol) in 32 children/adolescents (8–17 years) with Rome IV DGBI. Primary outcome was gastrointestinal symptoms (PedsQL Gastrointestinal Symptoms Short Scale) assessed at baseline, during treatment and post-treatment. Linear mixed models estimated within-group changes and Cohen's d effect sizes. Among 32 included participants, 25 (78%) completed the program and provided post-treatment data. Moderate to large within-group improvements in PedsQL gastro scores were reported (child d = 0.63; parent d = 0.81, p < .001). Clinically significant improvement (>30%) in GI symptoms was observed in 40% of completers. Pain intensity decreased modestly (child d = 0.24; parent d = 0.28, p < .005). Authors conclude the program appears feasible and acceptable and recommend an RCT to confirm efficacy.

Key findings

  • Within-group improvement in gastrointestinal symptoms measured by the PedsQL Gastrointestinal Symptoms Short Scale (child report).d = 0.63, p < .001
  • Within-group improvement in gastrointestinal symptoms measured by the PedsQL Gastrointestinal Symptoms Short Scale (parent report).d = 0.81, p < .001
“The primary outcome was gastrointestinal symptoms, measured by the PedsQL Gastrointestinal Symptoms Short Scale.”
What this piece can’t prove
  • Uncontrolled, single-arm pre/post design — no randomized or active comparator to control for placebo, regression to the mean, or natural history.
  • Small sample size (n = 32 included; n = 25 completers) limits precision and generalizability.
  • Outcome assessment relied on patient- and parent-reported measures; potential reporting bias.
  • Abstract reports only short-term (post-treatment) outcomes; no longer-term follow-up data presented.
