Clinical Trial Summary

This pilot-study aims to evaluate the treatment effects and feasibility of an internet-delivered CBT-program adjusted for adolescents with functional abdominal pain and functional dyspepsia.

Description:

Functional abdominal pain (FAP) and functional dyspepsia, are common in adolescents and associated with impaired quality of life. In adults with IBS, internet-delivered CBT leads to reduced symptoms and increased quality of life, but studies in children are lacking. This pilot-study aim to evaluate the treatment effects and feasibility of an internet-delivered CBT-program for adolescents with FAP and FD.

Method: Pilot study with a pre-post-design and no control group. The internet-delivered CBT-program will last for 10 weeks and include weekly therapist support, consisting of online messages and telephone calls.

Intervention

Behavioral:
• Internet-delivered CBT
The Internet-delivered exposure treatment is based on the well-established internet-delivered CBT-treatment for IBS in adults, adapted for adolescents with FAP/FD and their parents. Main component in the treatment is exposure for symptoms. The purpose of the treatment is to reduce fearful and anxious responses to symptoms and lessen avoidance of symptoms in the adolescents, and to teach the parents how parental behavior can influence symptoms in children as well as how to support exposure. Detailed behaviour analysis is made for each individual and instruction is given on how to gradually expose to symptoms to lessen fear for symptoms and widen the behavioral repertoire.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Faces pain scale - R	Change in pain intensity measured with a self-rating scale daily during 2 weeks at baseline and daily during 10th to 12th week post treatment for analysis of effect.The Faces Pain Scale is a self-report measure used to assess the intensity of children's pain. Faces have four faces representing least pain and most pain on equal intervals on a scale from 0-10. Its validity is supported by a strong positive correlation (r=0.93, N=76) with a visual analogue scale (VAS) measure in children aged 5-12 years. The metric for scoring (0-10) conforms closely to a linear interval scale.	Baseline to 12 weeks.
Secondary	Faces pain scale - R	Change in pain intensity measured with a self-rating scale daily during 2 weeks at baseline and daily during 2 weeks after 9 months for analysis of effect.The Faces Pain Scale is a self-report measure used to assess the intensity of children's pain. Faces have four faces representing least pain and most pain on equal intervals on a scale from 0-10. Its validity is supported by a strong positive correlation (r=0.93, N=76) with a visual analogue scale (VAS) measure in children aged 5-12 years. The metric for scoring (0-10) conforms closely to a linear interval scale.	Baseline to 9 months
Secondary	Faces pain scale - R	Change in pain intensity measured with a self-rating scale weekly during treatment for mediation analyses.	Weekly during treatment (treatment week 1-9).
Secondary	Gastrointestinal Symptom Rating Scale-IBS Version (GSRS-IBS)	Change in gastrointestinal symptoms measured with a self-rating scale from baseline to 10 weeks, and from baseline to 9 months for analysis of effect.The GSRS-IBS have 13 items about weekly gastrointestinal symptoms like bloating, hard stool, abdominal pain etc. It is a seven-point Likert scale from 1 (no discomfort at all) to 7 (very severe discomfort). The GSRS-IBS has excellent psychometric properties with internal consistency between a = .74 (for abdominal pain) to a = .85 (for satiety).	Baseline to 10 weeks, baseline to 9 months
Secondary	IBS-behavioral responses questionnaire (IBS-BRQ)	Change in Gastrintestinalsymptoms-specific behaviors measured with a self-rating scale weekly during treatment for mediation analyses, and from baseline to 10 weeks, baseline to 9 months, for analysis of effect. The scale consists of 26 items on a seven-point Likert scale from 1 (never) to 7 (always). The scale includes items related to avoidance behavior such as "I avoid certain social situations (e.g. restaurants) because of my symptoms " and to toilet behavior such as "I spend more time on the toilet than ideally I would like". IBS-BRQ is both reliable and valid with a high degree of internal consistency for adults with IBS (Cronbach's a=.86). The scale differentiate significantly between IBS patients and healthy controls (F=221, P<.01).	Weekly during treatment (treatment week 1-9). Baseline to 10 weeks, baseline to 9 months.
Secondary	Percieved Stress scale (PSS 10)	Change in perceived stress measured with a self-rating scale weekly during treatment for mediation analyses, and from baseline to 10 weeks, baseline to 9 months for analysis of effect. The PSS measures the degree to which situations are appraised as stressful. It is a self-report scale with 10 items on daily hassles and the current feeling of being able to handle problems that need to be addressed. It is a five-point Likert scale ranging from 0 (never) to 4 (very often). It is a widely used questionnaire to measure perceived stress and has adequate internal and test-retest reliability.	Weekly during treatment (treatment week 1-9). Baseline to 10 weeks, baseline to 9 months.
Secondary	Pain reactivity Scale (PRS)	Change in pain reactivity measured with a self-report scale, pain reactivity scale (PRS), at baseline to 10 weeks, baseline to 9 months. PRS have 5 items about reactivity to and worry about pain. Three items are about emotional reactions to current pain. Two items affect frequency of worry about not being able to do things now, and in the future because of the pain. Questions are answered on a 6-point scale from 0 ("not at all") to 6 ("very much"). PRS has been reported to have satisfactory psychometric properties (Wicksell et al, 2011)	Baseline to 10 weeks, baseline to 9 months,
Secondary	Pain interference index (PII)	Change in pain interference measured with a self-report scale at baseline to 10 weeks, baseline to 9 months. Pain interference index (PII), have 6 items about interference on various activities because of pain. Questions are answered on a 6-point scale from 0 ("not at all") to 6 ("very much").

Questions are related to specific activities such as climbing stairs, running 100 meters and to go shopping, and general activities such as eating meals and being in school all day. The scale ranges from 1 (no problem at all) to 5 (impossible). It is validated for children and adolescents with chronic abdominal pain with high internal consistency, a = .86 for boys and a = .91 for girls (Claar and Walker, 2006). FDI is the scale that is recommended in pediatric pain studies to measure the influence of pain on function (McGrath et al., 2008).	Baseline to 10 weeks, baseline to 9 months.
