Measures quality of life with a minimum value of zero and a maximum value of 100. Higher score indicates better outcome.

Measures criteria for Somatic Symptom Disorder (SSD) and symptoms' burden: The total score ranges between 0 and 48, with a higher score reflecting higher levels of the psychological features of the SSD, or worse outcome.

Measures causal attributions individuals make of common somatic symptoms by using three sub scales: somatic (range 13-36), psychological (range: 13-52), and environmental/normalizing (range: 17-49). Each sub score represents the extent with which each sub scale is endorsed as a possible cause for symptoms (higher score means higher outcome).

Measures Chemical Sensitivity with 5 subscales: Symptoms, Chemical Intolerances, Other Intolerances, Masking, and Life Impact.

Patients with no intolerance to chemicals only complete the subscales on Symptoms.

Measures sensitivity to Electromagnetic Fields. The score can range from 0 to 54 (high score representing high annoyance/intolerance and worse outcome). Only patients reporting intolerance to Electromagnetic fields complete this questionnaire.

Measures Modern Health Worries (concerns of respondents about modern environmental issues). Scores range from 12 to 60 with higher scores indicating more concern or worse outcome.

Measures Climate Change Anxiety with scores ranging from 13 to 65 and higher scores indicating higher levels of climate change anxiety, or worse outcome.

Measures Depression and Anxiety. Score ranges from 0 to 21 with higher score representing worse outcome.

Measures Intolerance to Uncertainty with total scores ranging from 12 to 60 with higher score representing worse outcome. The total scores encompasses two sub-scales: prospective anxiety and inhibitory anxiety. A greater score in each subscale indicates a greater level of prospective anxiety and inhibitory anxiety.

Measures body awareness and autonomic stress response patterns. Scores range from 12 to 60. Particularly high scores may indicate the autonomic nervous system is frequently activated by stress or chronic threat responses (i.e. worse outcome)

Measures the Level of Emotional Awareness with a maximum score of 50. Higher scores indicating greater awareness and differentiation in emotions, or better outcome.

measures how people think and feel regarding utilizing psychological healthcare. This 24-item scale assesses 3 internally consistent factors: psychological openness, help-seeking propensity, and indifference to stigma. Participants answer the questions using a 5-item scale (0 = disagree; 4= agree). Higher scores on the indifference to stigma scale reflect a positive stance towards mental healthcare services, while higher scores on the other two subscales reflect a more negative attitude.

Consists of 6 questions with an open answer format and assesses the number of medical and paramedical visits, therapists' visits, physical exams, as well as medication and dietary supplements consumed over the last 3 months.

Measure three dimensions of working alliance: agreement on therapeutic goals, consensus on tasks, and affective bond between client and therapist. The questionnaire consists of eight items measured on a five-point scale (1=never to 5=always), as well two open questions for feedback to the therapist. A higher score indicates a better client-therapist relationship.

Studies how negative affective stimuli influence somatic symptom perception. Negative and neutral pictures are presented to participants and after each picture series, participants fill in a short questionnaire about their current symptoms and affective state.

Monitors symptoms during 2X10 mins exposure to environmental agents patients attribute symptoms to (wifi box or chemicals) and 1X10 mins control without exposure. Patients can stop the task at all times.

This task was developed to investigate information processing and belief updating in light of desirable or undesirable information. Patients rate their own risk for negative events, some of them related to environmental hazards, as compared to baseline risks in the general population.

Explores patients' feedback after receiving the traitement protocole, in 8 questions from 1 to 4 (high score representing high satisfaction) and 2 open questions for comments and suggestions.
