Summary The prevalence of mental health problems in university students worldwide is well-established and extremely concerning. The scoping review synthesises findings from 40 empirical studies published in peer-reviewed journals, giving valuable insights into mental health problems in FGS and highlighting significant gaps in our understanding. In addition to specific diagnosable mental health conditions, such as those found in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5; American Psychiatric Association [APA], 2013), university students experience more general mental health concerns—for example, stress (Adams et al, 2016), test anxiety (Janke et al, 2017) and financial distress (House et al, 2020). The deleterious effects of mental health problems on university students have serious consequences for academic success in terms of compromised performance and persistence—for example, a US study found that depression was a significant predictor of lower academic achievement and higher probability of dropping out (Eisenberg et al, 2009). Studies were included if they focused on more general mental ill health concerns and problems not found in the DSM-5 (APA, 2013)—for example, distress, stress or test anxiety. The quantitative studies included in the scoping review discussed mental health problems that had been determined using self-report scales, for example the Depression, Anxiety and Stress Scales (DASS; Lovibond & Lovibond, 1995), rather than diagnostic tests such as the DSM-5 (APA, 2013). Nine studies included in the scoping review found that FGS had significantly more mental health problems than CGS in terms of stress (Simmons et al, 2018), stress and depression (Stebleton et al, 2014; Stebleton & Soria, 2012), anxiety and depression (Keefe et al, 2020; Kroshus et al, 2021), anxiety and financial stress (Cadaret & Rieder Bennett, 2019), acculturative stress (Corona et al, 2017) test anxiety (Janke et al, 2017) and financial anxiety (Potter et al, 2020). Three studies included in the scoping review demonstrated that family support is a protective factor for FGS mental health in terms of stress (Wang & Castañeda-Sound, 2008), stress and depression (Suwinyattichaiporn & Johnson, 2020) and stress, anxiety and depression (Jeong et al, 2021). In addition to the psychological effects of mental health problems, several studies included in the scoping review demonstrated the repercussions for FGS academic success. The scoping review may reflect that stress, anxiety and depression are the most prevalent mental health problems in university students generally. Evidence from the studies included in the scoping review was mixed on whether mental health problems are significantly worse in FGS than CGS. Much more research is needed on mental health problems in FGS to ensure that widening participation is not just a laudable aim and that FGS thrive as well as arrive
