Effectiveness of an online positive psychology intervention among Tunisian healthcare students on mental health and study engagement during the Covid-19 pandemic

Research indicates that university students present higher levels of psychological distress compared with non-student age-matched youth. These levels are higher among healthcare students, and even higher during the Covid-19 pandemic. Therefore, cost-effective large-scale interventions are needed in order to prevent further development of psychological distress during this period, and more generally. The aim of the current study was to assess the effectiveness of an 8-week Internet-based positive psychology intervention for healthcare students in Tunisia. A two-armed randomized controlled trial was conducted among a sample of 366 health care students (183 in the experimental group and 183 in the control group), with a majority of women (94%). The average age was 20.74 years (±1.64). The participants completed the following online questionnaires at three time-points (before the program, immediately after, and three months later): stress, anxiety, depression, emotional regulation, optimism, hope, study engagement, and well-being. Repeated-measures ANOVAs revealed significant positive effects of the intervention on all the measured variables for the experimental group. The results showed a significant improvement immediately after the intervention compared to the control group, which was maintained three months later. This program may thus be considered as a promising means of improving students’ mental health and study engagement.
