Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Persistent physical symptoms (PPS) might diminish studying or workability and daily functioning without a clear medical or environment-related explanation. Psychosocial, patient-involving treatments that support individuals' abilities managing with the PPS and health behaviours have shown promising effects in treating PPS but the acceptability of these treatments among symptomatic individuals is low.

This study aims to assess the effectiveness of an eHealth intervention based on relational frame theory and acceptance and commitment therapy on PPS with two focus groups, among participants with indoor air associated disabling symptoms or persistent, chronic fatigue.

This study will compare web program enhanced with video-based individual case formulation with treatment as usual. The web program includes 10 one weeks (pilot included 6 two weeks) modules. In addition to patient-reported outcomes, ecological momentary assessments are conducted to provide real-time data on functioning and national registers are used to obtain information on health-care use and social benefits.

Data collection begins in August 2020 and will continue until 2023.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background: Frequent physical symptoms are common in the general population with over 90 per cent of the population reporting symptoms at some level. In some cases, they become persistent diminishing workability and daily functioning and associate with increased healthcare usage and sick leaves independently of other somatic or psychiatric comorbidities. Persistent physical symptoms (PPS) challenge health care systems as it is estimated that up to 4-30 per cent of primary health care visits are due to PPS without a clear medical explanation. Psychosocial, patient-involving treatments, such as cognitive-behavioural psychotherapy (CBT), that support individuals' abilities managing with the PPS and health behaviours have shown promising effects in treating PPS but so far, evidence-based treatments have resulted only in small to moderate effect sizes. The acceptability of these treatments among symptomatic individuals is also low - presumably because of the stigma related to the ambiguity of the PPS´ status as a medical condition. A stronger orientation to personalized treatment protocols is needed to improve the treatment efficacy and applicability.

This study will assess the effects of an eHealth intervention based on relational frame theory and acceptance and commitment therapy on PPS with two focus groups, among participants with indoor air associated disabling symptoms or persistent, chronic fatigue.

Methods: Using a randomized controlled design (RCT) with two parallel groups in a 1:1 ratio, the investigators will compare ACT/RFT-based web program enhanced with individual case formulation with treatment as usual. The web program intervention includes 10 one weeks (pilot included 6 two weeks) modules that each ask to complete the module and included training in two weeks. The web program is in Finnish. Participants will be asked to complete outcome questionnaires at baseline before the interview for inclusion, after the interview (randomization) and at 3, 6- and 12-months' follow-up after the randomization. The intervention group receives also a questionnaire four weeks after the beginning of the web program. In addition, ecological momentary assessments are also conducted to provide real-time data on functioning and national registers are used to obtain information on healthcare use and social benefits to complete patient-reported outcomes.

Eligible participants will be randomized to either the intervention or to TAU. The primary outcome will be a health-related quality of life. The secondary outcome measures are symptoms, illness perceptions, psychological flexibility and workability. Further, the investigators will assess whether any effect of the intervention on the primary outcome is mediated by the case formulation. The baseline data collection begins in August 2020 and will continue until 2022, follow-up data collection will continue until 2023.

Caregivers Outcome Assessors

The randomization will be pre-programmed and the allocation sequence will be carried out and concealed by a researcher who is not otherwise involved in trial at FIOH. This study compares eHealth intervention with treatment as usual. Thus it is not possible to blind the study participants. However, eHealth therapists are blinded for study participant compared with patients in eHealth intervention for other reasons, I.e. study participants and patients referred to the program as treatment as usual by their physician. Further, data analyst will be blinded to intervention arms.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Case formulation with web-program

The intervention will start with two video meetings with a psychologist to build up and present an individual case formulation, based on behavioural analysis, and to build up a shared decision of individual goals for the web program. The intervention continues with a web program consisting of ten manualized web-based modules, each at one-week intervals based on relational frame theory (RFT) and acceptance and commitment therapy (ACT). The pilot programme included six two-weeks modules and it was in use until 5/2021. The programme is in Finnish.

Both participants in the intervention arm and in the treatment as the usual arm will receive usual care, meaning that TAU will be enhanced with the study intervention in the intervention arm. In addition to TAU, all participants will be given self-help and educational leaflet based on scientific knowledge related to their condition.

Group Type EXPERIMENTAL

Case formulation with web-program

Intervention Type BEHAVIORAL

The first meeting includes an interview to establish understanding on the participant´s symptomatology and current life situation, a case formulation (CF) will be build based on it. The CF is presented in the second session and modifications can be made to ensure acceptability for the participant. Goals for web program (WB) are set based on the CF and understanding of the factors contributing to the participant´s wellbeing.

WB modules are instructed to complete during the week. Modules include psychoeducation, experiential exercises and training aimed at improving wellbeing and psychological flexibility. Web-therapist will offer written feedback. The participants can contact the therapist via the WB and al messages will be replied within one week. Automatic reminders will be sent if a participant has not been active in the WB, the therapists will call participants who have discontinued using the WB.

Treatment as usual

Treatment as usual includes all the routine care that individual receives when he or she is presenting his or her symptoms at the primary or the occupational health care unit (corresponds primary care level treatment) or other unit that recommends the study for the participant. In practice, TAU may vary between the study participants based on their individual needs e.g. treatments for co-morbid somatic diseases or psychiatric disorders that this study will not interfere.

Both participants in the intervention arm and in the treatment as usual arm will receive usual care, meaning that TAU will be enhanced with the study intervention in the intervention arm. In addition to TAU all participants will be given self-help and educational leaflet based on scientific knowledge related to their condition.
