ICBT for Children With FAPDs - the Child's Pain Regulation

Recruiting
Conditions
Functional Abdominal Pain Syndrome
Interventions
Other: Internet-delivered cognitive behavioral therapy
Registration Number
NCT05945251
Lead Sponsor
Karolinska Institutet
Brief Summary

Functional abdominal pain disorders (FAPDs) in children are common (14%) and abdominal pain has increased rapidly in children during the last ten years in Sweden. Many children with FAPDs have low quality of life, missed school days, and about 30-40% suffer from psychiatric comorbidity. FAPDs are often sustained into adulthood and a large Swedish cohort study showed that abdominal pain during childhood is an independent strong predictor anxiety and depression later in life. Internet-cognitive behavioral therapy (Internet-CBT) can improve FAPD symptoms, but a significant number of children does not respond to the treatment.

We will here determine the pain regulation in children with FAPDs, compared with healthy controls, and assess:

What aspects of the child's pain regulation is related to improvement for children with FAPDs engaging in Internet-CBT?

Does some aspects of the child's pain regulation change during treatment?

Primary Outcome Measures
NameTimeMethod
Unpleasantness of pressure pain threshold on navelBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Children rate their unpleasantness on a scale 0-10

Pressure pain threshold on navelBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Algometer pressure (in kPa) for the pain threshold

Secondary Outcome Measures
NameTimeMethod
Conditioned pain modulationBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Conditioned pain: hand in 10°C cold water, test pain: presseure pain thresholds by algometer on the participant's thigh. Difference in pressure pain thresholds with and without the simultaneous conditioned stimuli

Irritable bowel syndrome-behavioral responses questionnaire, child-adapted short version (BRQ-C)Baseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Self-assessed questionnaire of gastrointestinal-specific avoidance and controlling behaviors

Unpleasantness of pressure pain threshold on thighBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Children rate their unpleasantness on a scale 0-10

Sensory attenuation of painBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Pressure pain thresholds (kPa) applied by the child or the experimenter. Sensory attenuation = difference in pain threshold between self-induced and experimenter induced

Visceral sensitivity Index, child-adapted short version (VSI-C)Baseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Self-assessed questionnaire of gastrointestinal-specific anxiety

Temporal summationBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Pinprick stimuli of low pain, one time, then repeated 10 times. Pain after repeated stimulus minus pain for the single stimulus.

Resting state fMRIBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Differences in network connectivity (Yeo networks + subcortical areas) and between seed (trunk in the somatosensory cortex) to Yeo brain networks + subcortical areas).

Pediatric Quality of Life Inventory Gastrointestinal Symptom Scale (PedsQL Gastro)Baseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Self-assessed questionnaire of abdominal symptoms

Faces Pain Rating Scale (FACES)Baseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Self-assessed questionnaire of pain intensity

Pressure pain threshold on thighBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Algometer pressure (in kPa) for the pain threshold

fMRI during low pain compared with non-painful tactile stimulusBaseline differences and baseline to follow-up after 10 week's treatment (or 10 week's wait for healthy children)

Differences in network connectivity (Yeo networks + subcortical areas) and between seed (trunk in the somatosensory cortex) to Yeo brain networks + subcortical areas).
