Abstract

BACKGROUND: Depression and anxiety are common mental health difficulties experienced by university students and can impair academic and social functioning. Students are limited in seeking help from professionals. As university students are highly connected to digital technologies, Web-based and computer-delivered interventions could be used to improve students' mental health. The effectiveness of these intervention types requires investigation to identify whether these are viable prevention strategies for university students. OBJECTIVE: The intent of the study was to systematically review and analyze trials of Web-based and computer-delivered interventions to improve depression, anxiety, psychological distress, and stress in university students. METHODS: Several databases were searched using keywords relating to higher education students, mental health, and eHealth interventions. The eligibility criteria for studies included in the review were: (1) the study aimed to improve symptoms relating to depression, anxiety, psychological distress, and stress, (2) the study involved computer-delivered or Web-based interventions accessed via computer, laptop, or tablet, (3) the study was a randomized controlled trial, and (4) the study was trialed on higher education students. Trials were reviewed and outcome data analyzed through random effects meta-analyses for each outcome and each type of trial arm comparison. Cochrane Collaboration risk of bias tool was used to assess study quality. RESULTS: A total of 17 trials were identified, in which seven were the same three interventions on separate samples; 14 reported sufficient information for meta-analysis. The majority (n=13) were website-delivered and nine interventions were based on cognitive behavioral therapy (CBT). A total of 1795 participants were randomized and 1480 analyzed. Risk of bias was considered moderate, as many publications did not sufficiently report their methods and seven explicitly conducted completers' analyses. In comparison to the inactive control, sensitivity meta-analyses supported intervention in improving anxiety (pooled standardized mean difference [SMD] -0.56; 95% CI -0.77 to -0.35, P<.001), depression (pooled SMD -0.43; 95% CI -0.63 to -0.22, P<.001), and stress (pooled SMD -0.73; 95% CI -1.27 to -0.19, P=.008). In comparison to active controls, sensitivity analyses did not support either condition for anxiety (pooled SMD -0.18; 95% CI -0.98 to 0.62, P=.66) or depression (pooled SMD -0.28; 95% CI -0.75 to -0.20, P=.25). In contrast to a comparison intervention, neither condition was supported in sensitivity analyses for anxiety (pooled SMD -0.10; 95% CI -0.39 to 0.18, P=.48) or depression (pooled SMD -0.33; 95% CI -0.43 to 1.09, P=.40). CONCLUSIONS: The findings suggest Web-based and computer-delivered interventions can be effective in improving students' depression, anxiety, and stress outcomes when compared to inactive controls, but some caution is needed when compared to other trial arms and methodological issues were noticeable. Interventions need to be trialed on more heterogeneous student samples and would benefit from user evaluation. Future trials should address methodological considerations to improve reporting of trial quality and address post-intervention skewed data.

  • Internet-delivered CBT has demonstrated effectiveness in addressing anxiety disorders and depression in college samples.

    “Internet-delivered CBT has demonstrated effectiveness in addressing anxiety disorders and depression in both the general population [23–25] and in college samples [26, 27].”

    From An internet-delivered acceptance and commitment therapy program for anxious affect, depression, and wellbeing: A randomized, parallel, two-group, waitlist-controlled trial in a Middle Eastern sample of college students (2024) · cites this paper as [27]

    The Results section reports improved anxiety and depression outcomes in university students compared with inactive controls, and the Conclusions say the findings support self-guided Internet-delivered CBT. The review measures anxiety outcomes rather than establishing effectiveness for diagnosed anxiety disorders, and it cautions that the findings are methodologically limited and show no significant advantage over active controls. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The consistent improvements in the intervention group on both anxiety measures and wellbeing are in concurrence with preceding literature on internet-delivered ACT and mindfulness programs.

    “The consistent improvements in the intervention group on both measures of anxiety, the generalized and social anxiety variants, as well as wellbeing are in concurrence with the preceding literature”

    From An internet-delivered acceptance and commitment therapy program for anxious affect, depression, and wellbeing: A randomized, parallel, two-group, waitlist-controlled trial in a Middle Eastern sample of college students (2024) · cites this paper as [27]

    In Results > Web-Based or Computer-Delivered Intervention Compared to Inactive Control (page unavailable), the review reports improved anxiety outcomes for web-based or computer-delivered interventions overall. Results > Intervention Characteristics and Participant Satisfaction/Evaluation (pages unavailable) identify a mindfulness intervention and report perceived personal benefit, but do not establish improvements in both generalized and social anxiety or well-being from internet-delivered ACT and mindfulness programs. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Computer-based e-mental health programs with a CBT framework have been found effective for improving happiness and well-being.

    “and improving happiness and well-being [21-23].”

    From Apps with maps-anxiety and depression mobile apps with evidence-based frameworks: Systematic search of major app stores (2020) · cites this paper as [21]

    The Results (Intervention Characteristics) include programs aimed at general psychological well-being, and the Discussion (Conclusions) cautiously supports the effectiveness of Internet-delivered CBT for university students’ mental-health outcomes. The paper does not report an improvement in happiness specifically, and its demonstrated benefits chiefly concern depression, anxiety, and stress rather than a measured overall well-being outcome. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The aforementioned meta-analyses showed positive results on depressive symptoms with effect sizes in a small range.

    “Although the aforementioned meta-analyses showed positive results on depressive symptoms with effect sizes in a small range”

    From Meta-analytic review of online guided self-help interventions for depressive symptoms among college students (2021) · cites this paper as Davies et al., 2014

    The Results (Web-Based or Computer-Delivered Intervention Compared to Inactive Control; page unavailable) report a significant improvement in depressive symptoms in the sensitivity meta-analysis (SMD −0.43), consistent with a relatively small effect. But the non-skewed analysis found a larger effect (SMD −0.67), and the paper did not find a significant benefit against active controls. The claim omits those distinctions. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • All previous meta-analyses combined guided and unguided self-help interventions in their investigations and there was substantial variation in the degree of success for included programs.

    “all authors combined guided and unguided self-help interventions in their investigations and there was substantial variation in the degree of success for included programs”

    From Meta-analytic review of online guided self-help interventions for depressive symptoms among college students (2021) · cites this paper as Davies et al., 2014

    The Results (Use of Human Support in Interventions; page unavailable) identify both self-administered and semi-guided trials, and the Discussion (Principal Findings; page unavailable) says the review did not compare their effects. The Discussion also reports moderate to high heterogeneity in two analyses, supporting variation in outcomes. The paper does not establish that all previous meta-analyses combined guided and unguided interventions. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
