The Claim
In adults with irritable bowel syndrome, higher levels of pain catastrophizing are associated with a reduced therapeutic benefit from open-label placebo interventions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with irritable bowel syndrome who experience greater feelings of helplessness and hopelessness about their pain show less improvement when given a transparent placebo treatment.
See the scientific wording
In adults with irritable bowel syndrome, pain catastrophizing is associated with reduced benefit from open-label placebo, suggesting that feelings of helplessness and hopelessness may interfere with therapeutic responses to transparent, self-directed interventions.
When a person feels hopeless about their pain, the brain reduces natural pain-relieving chemicals, making it harder for even honest placebo treatments to activate the body’s own pain control system.
What the research says
1 studyPeople with IBS who feel hopeless about their pain didn’t improve as much when they were told they were taking a fake pill, even though the pill worked for others. This suggests that feeling helpless can block the power of being honest about treatment.
