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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Case formulation with web-program | Experimental | 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. |
|
| Treatment as usual | No Intervention | 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. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Case formulation with web-program | 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. |

| The 15D questionnaire (health related quality of life) | The 15D is a utility-based generic, standardized measure, comprising the following 15 dimensions that describe physical, mental, and social well-being: mobility, vision, hearing, breathing, sleeping, eating, speech, excretion, usual activities, mental function, discomfort and symptoms, depression, distress, vitality, and sexual activity. Each dimension is graded by the respondent on a scale ranging between 1 and 5, where 1 indicates an experience of no problems at all with the dimension and 5 indicates severe problems. Thus, the 15D can be used to measure a vast number of health states. We will use the 15D data both to derive 15D overall scores with values from 1 (full health) to 0 (being dead), and to obtain dimensional symptom profiles. | Chance from baseline (i.e. at self-referral) to after randomisation (i.e. after clinical assessment), and to 6 and 14 weeks and to 6 and to 12 months after randomisation |

All IPD that underlie results in a publication could be published But: study participants choose in informed consent that do they accept that their IPD will be published (anonymized). If they choose 'no´, their data won´t be published. Thus the preliminary plan is not to share the IPD (´undecided' would be accurate as well).

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.
