New in Town-An internet-based self-efficacy intervention for internal migrants: A randomized controlled trial

Migration is a profound life transition that may threaten migrants' well-being and mental health. Results of several studies suggest that social self-efficacy beliefs may be beneficial for the psychological adjustment of migrants, buffering the effect of specific stressors related to migration, helping them reduce anxiety levels, and providing support in forming of new social bonds and better integration with a new community or culture. The primary purpose of this randomized controlled trial was to examine the effectiveness of the New in Town internet-based self-efficacy intervention for internal migrants in Poland.

Participants were 158 internal adult migrants who had changed residence in the last 6 months. They were randomized into two groups: an experimental group (receiving an internet-based self-efficacy intervention), and a waiting list control group. We examined if the intervention was effective in enhancing participants' social self-efficacy (primary outcome), general self-efficacy, social support, satisfaction with life, and reduced reported loneliness (secondary outcomes). Outcome measures were assessed at baseline (Time 1) and 3-weeks later (Time 2). The dropout rate was 50.6%. Initially, we planned to gather follow-up data also 8-weeks after baseline (Time 3). However, due to health and safety reasons related to the COVID-19 pandemic, we decided to stop the trial. Finally, we included in our analysis only data gathered before the COVID-19 pandemic at Time 1 and Time 2.

A total of 159 individuals who met the study's inclusion criteria and completed the baseline assessment were randomly assigned to either the experimental group (n = 80) or the waiting list control group (n = 79). Nevertheless, one participant assigned to the control group was excluded from the analyses because they withdrew their consent to participate after being randomized. The study results suggest that compared to the waitlist control group (n = 78), participants in the experimental group (n = 80) reported a higher level of general self-efficacy beliefs at Time 2 (Cohen's d = 0.47; 95% CI: 0.15-0.79). However, there were no statistically significant effects on social self-efficacy, social support, satisfaction with life, and loneliness.

The study offers preliminary support for the effectiveness of an internet-based self-efficacy intervention designed for internal migrants on general self-efficacy beliefs.

The trial was registered with ClinicalTrials.gov (identifier: NCT04088487) on 11th September 2019.
