Plain English Summary
Background and study aims
Medically unexplained symptoms (MUS) are quite common in general practice. Referral to medical specialists does not reveal an organic cause and patients are referred back to their general practitioner. This results in frequent consultations without symptom reduction. These patients are costly not only because of direct medical costs, but also because of indirect costs resulting from sick leave and presenteeism. Existing approaches are not self-evident for migrant and low educated patients. Therefore, an alternative intervention has been developed in the Netherlands designed for female migrant patients who frequently visit their general practitioner and experience low levels of energy. The intervention aims to create opportunities to achieve positive experiences in different domains of life. Its purpose is to increase self-esteem and self-confidence which are necessary for empowerment, energy increase and quality of life. The aim of this study is to determine the cost-effectiveness of this new intervention as compared to care as usual.
Who can participate?
Female migrant patients, aged between 26 and 64, who had a contact with the participating general practices in this study
What does the study involve?
Participating general practices are randomly allocated to two groups, the intervention group and the control group. The intervention comprises a series of 13 group meetings including an introductory meeting, eight meetings that focus on specific themes, two visits to community centers or organizations, one concluding session and an evaluation meeting. The actual content of the group meetings is adapted to the specific group composition. The intervention takes place in groups because groups may contribute to the treatment goals: participants may stimulate and help each other, and it may help to increase their social network. Before the group meetings, an individual intake aims at defining the individual goals of each participating person. The intervention group meetings are guided by either a psychologist, a social worker or a socio-psychiatric nurse. Training for the intervention group has been provided shortly before the actual launch of the intervention by a coach, who was also involved in the development of the intervention. In the control group participants receive care as usual as provided by their GP. Patients’ quality of life and the costs (medical and non-medical) are measured 14 months later.
What are the possible benefits and risks of participating?
Possible benefits include better quality of life, higher energy level, higher self-esteem, more social contacts/support, less health complaints, and lower frequency of GP visits. No risks are expected.

Condition
Medically unexplained symptoms in general practice
Intervention
The study has been conducted in Rotterdam, the second largest city of the Netherlands. In Rotterdam 37,4% of the population has a non-western background. The study has been carried out in general practices willing to participate in the study and willing to give permission to make use of their patient information system for selection of patients. The study has been setup as a cluster randomized trial with two arms. Participating general practices were the clusters that were randomly allocated to two arms, the intervention group and the control group. Cluster randomization was chosen because the intervention was partly community oriented, which made it necessary that participants belonging to the same intervention group were living in the same neighborhood.
The intervention comprises a series of 13 group meetings including an introductory meeting, 8 meetings that focus on specific themes, two visits to community centers or organizations, one concluding session and an evaluation meeting. The actual content of the group meetings is adapted to the specific group composition. The intervention takes place in groups because groups may contribute to the treatment goals: participants may stimulate and help each other, and it may help to increase their social network. Prior to the group meetings, an individual intake aims at defining the individual goals of each participating person. The intervention group meetings are guided by either a psychologist, a social worker or a socio-psychiatric nurse. Training for the intervention group has been provided shortly before the actual launch of the intervention by a coach, who was also involved in the development of the intervention.
In the control condition participants received care as usual as provided by their GP

Primary outcome measure
1. Quality of life measured by SF-12 at baseline and follow-up (14 months later)
2. Costs (medical and non-medical) measured at baseline and follow-up
Secondary outcome measures
1. Depressive symptoms, assessed using the Patient Health Questionnaire-9 (PHQ-9). It assesses the presence of depressive symptoms in the past two weeks with four response options (‘not at all’, ‘several days’, ‘more than half the days’, ‘nearly every day’) and is often used in primary care settings The PHQ-9 score ranges from 0 to 27, because each of the 9 items can be scored from 0 (‘not at all’) to 3 (‘nearly every day’) . The PHQ-9 is part of the full PHQ for assessment of mental disorders.
2. Somatic symptoms, assessed using the Patient Health Questionnaire-15. The PHQ-15 is a validated instrument for detecting somatization disorders. The PHQ-15 comprises 15 somatic symptoms derived from the full PHQ. In this study 13 of the PHQ-15 somatic symptoms are included in the somatic symptom subscale. In this subscale patients are asked to rate the severity of each symptom as ‘not bothered at all’, ‘bothered a little’ or ‘bothered a lot’. Thus, in determining the score, each individual symptom is coded as 0, 1 or 2 and the total score ranges from 0 to 26. For Turkish speaking participants we made use of an existing Turkish translation of the PHQ.
2. Loneliness, measured using the De Jong Gierveld Loneliness Scale, a validated and reliable instrument for measurement of overall, emotional and social loneliness. The 6-item scale was used in which the patients are asked to what extent the statements apply to them. The scale consists of 6 statements on a 3-points scale (yes, more or less and no). Scale scores range from 0 to 6. Higher scores indicate higher loneliness.
3. Self-esteem, measured using the Rosenberg Self-Esteem Scale, a 10-item scale in which patients are asked to rate their agreement with 5 positively and 5 negatively worded self-statements on a 4-points scale ranging from ‘strongly agree’ to ‘strongly disagree’ The total score (that ranges from 0 to 30) is calculated such that higher scores reflect higher self-esteem.
Measured at face-to-face interviews at baseline (T0) and 14 months (T1) after inclusion
