Abstract

BACKGROUND: Depression is a worldwide problem warranting global solutions to tackle it. Enhancing well-being has benefits in its own right and could be a good strategy for preventing depression. Providing well-being interventions via the Internet may have synergetic effects. OBJECTIVE: Psyfit ("mental fitness online") is a fully automated self-help intervention to improve well-being based on positive psychology. This study examines the clinical effects of this intervention. METHODS: We conducted a 2-armed randomized controlled trial that compared the effects of access to Psyfit for 2 months (n=143) to a waiting-list control condition (n=141). Mild to moderately depressed adults in the general population seeking self-help were recruited. Primary outcome was well-being measured by Mental Health Continuum-Short Form (MHC-SF) and WHO Well-being Index (WHO-5); secondary outcomes were depressive symptoms, anxiety, vitality, and general health measured by Center for Epidemiological Studies Depression Scale (CES-D), Hospital Anxiety and Depression Scale Anxiety subscale (HADS-A), and Medical Outcomes Study-Short Form (MOS-SF) vitality and general health subscales, respectively. Online measurements were taken at baseline, 2 months, and 6 months after baseline. RESULTS: The dropout rate was 37.8% in the Psyfit group and 22.7% in the control group. At 2-month follow-up, Psyfit tended to be more effective in enhancing well-being (nonsignificantly for MHC-SF: Cohen's d=0.27, P=.06; significantly for WHO-5: Cohen's d=0.31, P=.01), compared to the waiting-list control group. For the secondary outcomes, small but significant effects were found for general health (Cohen's d=0.14, P=.01), vitality (d=0.22, P=.02), anxiety symptoms (Cohen's d=0.32, P=.001), and depressive symptoms (Cohen's d=0.36, P=.02). At 6-month follow-up, there were no significant effects on well-being (MHC-SF: Cohen's d=0.01, P=.90; WHO-5: Cohen's d=0.26, P=.11), whereas depressive symptoms (Cohen's d=0.35, P=.02) and anxiety symptoms (Cohen's d=0.35, P=.001) were still significantly reduced compared to the control group. There was no clear dose-response relationship between adherence and effectiveness, although some significant differences appeared across most outcomes in favor of those completing at least 1 lesson in the intervention. CONCLUSIONS: This study shows that an online well-being intervention can effectively enhance well-being (at least in the short-term and for 1 well-being measure) and can help to reduce anxiety and depression symptoms. Further research should focus on increasing adherence and motivation, reaching and serving lower-educated people, and widening the target group to include people with different levels of depressive symptoms.

  • One study reported that almost 60% of participants with depression were indifferent to, or dissatisfied with, an online intervention using components of positive psychology.

    “One study reported that almost 60% of participants with depression were indifferent to, or dissatisfied with, an online intervention using components of positive psychology however, did not collect data on reasons for dissatisfaction [3].”

    From What might affect acceptability of online positive psychology interventions for depression: A qualitative study on patient expectations' (2018) · cites this paper as [3]

    The Results (Participant Satisfaction; page unavailable) report that 57.0% of the 93 intervention-group respondents were indifferent and/or dissatisfied with Psyfit, supporting the quoted finding. The Discussion (Adherence and Acceptability; page unavailable) says the authors collected no information on reasons for quitting or not starting, but does not specifically say they collected no data on reasons for dissatisfaction, as the full citing sentence claims. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Few studies have provided data to support the idea that positive psychology interventions are acceptable.

    “However, few studies have provided data to support the idea that positive psychology interventions are acceptable.”

    From What might affect acceptability of online positive psychology interventions for depression: A qualitative study on patient expectations' (2018) · cites this paper as [3]

    The Results > Participant Satisfaction section (page unavailable) provides acceptability-related data for one online positive psychology intervention: 43% of respondents were satisfied with Psyfit, while about 70% would recommend it. The paper does not establish that few studies have provided such data across positive psychology interventions; its review of prior studies concerns effectiveness, not the number assessing acceptability. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Given the widespread interest in taking positive psychology online for clinical and subclinical populations, it is salient to ensure that interventions are not undermined by issues of acceptability.

    “Given the widespread interest in taking positive psychology online for clinical and subclinical populations, [3, 5, 6] it is salient to ensure that interventions are not undermined by issues of acceptability [8].”

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.
