A Group-Facilitated, Internet-Based Intervention to Promote Mental Health and Well-Being in a Vulnerable Population of University Students: Randomized Controlled Trial of the Be Well Plan Program

Abstract

Background A growing literature supports the use of internet-based interventions to improve mental health outcomes. However, most programs target specific symptoms or participant groups and are not tailored to facilitate improvements in mental health and well-being or do not allow for needs and preferences of individual participants. The Be Well Plan, a 5-week group-facilitated, internet-based mental health and well-being group intervention addresses these gaps, allowing participants to select a range of activities that they can tailor to their specific characteristics, needs, and preferences. Objective This study aims to test whether the Be Well Plan program was effective in improving primary outcomes of mental well-being, resilience, anxiety, and depression compared to a waitlist control group during the COVID-19 pandemic; secondary outcomes included self-efficacy, a sense of control, and cognitive flexibility. The study further seeks to examine participants’ engagement and satisfaction with the program. Methods A randomized controlled trial (RCT) was conducted with 2 parallel arms, an intervention and a waitlist control group. The intervention involved 5 weekly 2-hour sessions, which were facilitated in group format using Zoom videoconferencing software. University students were recruited via social media posts, lectures, emails, flyers, and posters. Results Using an intentional randomization 2:1 allocation strategy, we recruited 215 participants to the trial (n=126, 58.6%, intervention group; n=89, 41.4%, waitlist control group). Of the 126 participants assigned to the intervention group, 75 (59.5%) commenced the program and were included in modified intention-to-treat (mITT) analyses. mITT intervention participants attended, on average, 3.41 sessions (SD 1.56, median 4); 55 (73.3%) attended at least 4 sessions, and 25 (33.3%) attended all 5 sessions. Of the 49 intervention group participants who completed the postintervention assessment, 47 (95.9%) were either very satisfied (n=31, 66%) or satisfied (n=16, 34%). The mITT analysis for well-being (F1,162=9.65, P=.002, Cohen d=0.48) and resilience (F1,162=7.85, P=.006, Cohen d=0.44) showed significant time × group interaction effects, suggesting that both groups improved over time, but the Be Well Plan (intervention) group showed significantly greater improvement compared to the waitlist control group. A similar pattern of results was observed for depression and anxiety (Cohen d=0.32 and 0.37, respectively), as well as the secondary outcomes (self-efficacy, Cohen d=0.50; sense of control, Cohen d=0.42; cognitive flexibility, Cohen d=0.65). Larger effect sizes were observed in the completer analyses. Reliable change analysis showed that the majority of mITT participants (58/75, 77.3%) demonstrated a significant reliable improvement in at least 1 of the primary outcomes. Conclusions The Be Well Plan program was effective in improving mental health and well-being, including mental well-being, resilience, depression, and anxiety. Participant satisfaction scores and attendance indicated a high degree of engagement and satisfaction with the program.

Remote Interventions to Support Students’ Psychological Well-Being during the COVID-19 Pandemic: A Narrative Review of Recent Approaches

“…The Be Well Plan program was effective in improving mental well-being, resilience, depression and anxiety. Participant satisfaction scores and attendance indicated a high degree of engagement and satisfaction with the program [ 36 ].…”

“…Moreover, four were supplemented by an additional follow-up examination [ 27 , 29 , 30 , 35 ]. An analysis of the statistical methods used revealed that three authors used univariate pre-post methods (Wilcoxon test, t-test, Mann-Whitney U test) [ 34 , 35 , 38 ], six authors used linear models [ 27 , 29 , 32 , 33 , 36 , 37 ], three studies employed analysis of variance [ 28 , 30 , 31 ].…”

The experience of individuals affected by Australia's international border closure during the COVID-19 pandemic

“…This could include educating health and mental health service providers about the significant negative impact these individuals had experienced as well as offering specific mental health support options for individuals who were born overseas or have family overseas. For example, it might be beneficial to provide individuals with digital resources that have been proven effective to improve mental health and wellbeing in other vulnerable populations ( Fassnacht et al, 2022 ). Future policy decisions should take the need for mental health support and the importance of connection to place into account when implementing measures such as international border closures during times of a crisis.…”

Effectiveness of Community-Based Outreach Interventions for Individuals Living with Mental Ill-Health in Australia: A Systematic Review

“…In addition to difculties with attrition and recruitment, many studies had insufcient outcome measures. Some digital interventions (n = 7; 17%) reported limitations regarding the use of self-report measures [30,39,40,42,44,48,59]. Measuring adherence also posed a challenge [28], and it was difcult to adjust for the lack of consistency across participants in the intervention content they accessed [39].…”
