About
The Covid-19 pandemic is having a great impact on the long-term mental health and well-being. Reports on the levels of psychological distress are concerning. This can be due to the pandemic, as well as social distancing, employment and economic consequences.
Healthcare workers, the elderly, youths, and persons experiencing socio-economic adversity are at risk of developing psychological distress. In this context, healthcare systems risk being overcharged, facing a growing demand.
Cognitive Behaviour Therapies managing psychological distress have been formally recommended. WHO has implemented different escalated psychosocial interventions, such as Problem Management Plus, PM+; Doing What Matters in Times of Stress, DWM; and Psychological First Aid, PFA. Their aim is to help individuals manage their stress in order to decrease the occurrence of psychological problems. They do not replace care for severe mental health disorders, but can prevent the deterioration of individuals' mental health.
PM+ has previously been found to be effective in situations of endemic conflict or violence in Pakistan and Kenya. The implementation of this program in Europe is being evaluated in the EU H2020 project STRENGHTS, focused in migrants from Syria. In the present trail, the investigators aim to further test its effectiveness in the context of psychological distress resulting from the COVID-19 pandemic.
Prior to the present trial, the investigators conducted a qualitative research study among potential beneficiaries and healthcare workers to evaluate the feasibility of DWM and PM+, which showed interest in stepped-care interventions in mental health, particularly if they are technology-based (mobile phones).
Our study is embedded in the larger, EU H2020 CORONAVIRUS-funded RESPOND project (Grant Agreement No 101016127). This project granted funding for a multicentric, single-blinded, randomised, controlled trial to evaluate the effectiveness of the stepped-care DWM and PM+ program vs. Care as Usual (CAU). In France, the investigators will focus on persons experiencing socioeconomic adversity, as defined by unstable housing conditions. A recent study showed that most of them are migrants. All subjects (210) will receive PFA and CAU. In addition to PFA and CAU, the treatment group (105 subjects) will receive the intervention DWM (with or without PM+). The primary outcome will be the decrease in symptoms of anxiety and depression from baseline to two-months follow-up.
Full description
STUDY POPULATION Our population is composed of adults (18 years or older), with unstable housing status , speaking one of the languages of the research (Arabic, Dari, French or Pashto).
CALCULATION OF THE SAMPLE SIZE Based on prior studies (Bryant et al., 2017; Rahman et al., 2016b), the investigators aim to detect a small to medium Cohen's d effect size of 0.3 in the PM+ group at 2 months post-treatment based on the primary composite outcome PHQ-ADS (Kroenke et al., 2016; 2019). The PHQ-ADS is the combined sum score of depression and anxiety symptoms of the PHQ-9 and GAD-7, respectively and has shown good internal consistency (α = .88 to .92) (Kroenke et al., 2016; 2019). A power calculation for a repeated measurement design (with STATA) suggests a minimum sample size of N=73 per group (power=0.80, alpha=0.05, two-sided, rho=0.9). Considering 30% attrition, the investigators aim to include a total number of 210 participants (105 in the stepped-care DWM/PM+ treatment group (with PFA and CAU) and 105 in the PFA and CAU comparison group).
STATISTICAL METHODS The statistical analysis will estimate the effectiveness of the stepped-care programs DWM/PM+ intervention compared to PSP and CAU alone.
The primary outcome (PHQ-ADS scale) will be summarized using the number of subjects (n), minimum and maximum; and means, standard deviations (SD) for normally distributed data, or medians and interquartile ranges for non-normally distributed data. To measure comparisons at baseline between the two treatment groups t-tests (continuous variables) or chi-squared tests (categorical variables) will be conducted for normally distributed data; Mann-Whitney tests will be conducted for continuous non-normally distributed data. Health economic analysis will be conducted to determine the difference in costs and outcomes in the intervention arm as compared to the care as usual group. Primary analysis will be the total costs over the 2-month follow-up treatment period. Between-group comparison of mean costs will be completed using standard t-test with ordinary least squares regression used for adjusted analysis, with the validity of results confirmed using bootstrapping.
ETHICAL CONSIDERATIONS This study will fully comply with relevant European and national regulations concerning data protection, privacy regulations, and the procedures for obtaining informed consent.
If a subject decides to withdraw from the study, the investigator will ask for the reason. Withdrawal from the study will have no effect on the regular treatment. Subjects who leave the study for medical reasons will be followed until the interfering condition has resolved or reached a stable state.
It is possible that participants experience stress during the PM+ sessions. The intervention will be supervised and strictly monitored by experienced psychologists. If a participant deteriorates during the intervention period, (s)he can be referred to an external specialist (licensed psychologist or psychiatrist). Whenever referral has taken place, it will be actively followed-up by the researchers. In case of an undesirable emotional reaction either during the intervention or during follow-up assessments, the researchers and clinicians will be available to provide support if necessary.
If a participant has elevated symptoms of psychological distress in follow-up assessments, (s)he will be advised to contact his/her general practitioner (part of the CAU), who may refer the participant for continued or high-intensity treatment.
• Compensation for injury
Participation in the study only carries negligible risks for the research subjects; therefore. An insurance has been taken by the study promotor to guarantee its civil responsibility, according to the French Public Health Code.
