Internet-based self-help intervention aimed at increasing social self-efficacy among internal migrants in Poland: Study protocol for a randomized controlled trial

Migration is a challenging life transition that may be a source of various problems related to well-being and mental health. However, the psychological adaptation of migrants may be potentially facilitated by social self-efficacy—the beliefs in one's ability to initiate and maintain interpersonal relationships. Previous research suggests that social self-efficacy is positively related to adjustment and negatively related to loneliness, depression, and psychological distress. Research also confirms that self-efficacy beliefs can be effectively enhanced using Internet-based interventions. These results served as a background for creating the New in Town, a self-help Internet-based intervention for internal migrants in Poland that aims at increasing social self-efficacy. Exercises in the intervention are based on the principles of Cognitive Behavioral Therapy and relate to sources of self-efficacy beliefs: mastery experiences, vicarious experiences, verbal persuasions, and emotional and physiological states. Users complete increasingly challenging tasks that encourage them to interact with their environment. The aim of this trial was to investigate the efficacy of the New in Town intervention. The efficacy of the New in Town intervention will be tested in a two-arm randomized controlled trial with a waitlist control group. Social self-efficacy will be the primary outcome. Secondary outcomes will include loneliness, perceived social support, and satisfaction with life. Additionally, we will measure user experience among participants allocated to the experimental group. We aim to recruit a total of N = 280 participants aged at least 18 years who have changed their place of residence in the last 6 months and have an Internet connection. Participants will be assessed at baseline, 3-week post-test, and 8-week follow-up. The trial will provide insights into the efficacy of Internet-based self-help interventions in increasing social self-efficacy. Given that the intervention works, New in Town could provide an easily accessible support option for internal migrants in Poland. The trial was registered with ClinicalTrials.gov (identifier: NCT04088487) on 11th September 2019.
