Abstract

Background: Depression is underdiagnosed and undertreated in primary health care. When associated with chronic physical disorders, it worsens outcomes. There is a clear gap in the treatment of depression in low- and middle-income countries (LMICs), where specialists and funds are scarce. Interventions supported by mobile health (mHealth) technologies may help to reduce this gap. Mobile phones are widely used in LMICs, offering potentially feasible and affordable alternatives for the management of depression among individuals with chronic disorders. Objective: This study aimed to explore the potential effectiveness of an mHealth intervention to help people with depressive symptoms and comorbid hypertension or diabetes and explore the feasibility of conducting large randomized controlled trials (RCTs). Methods: Emotional Control (CONEMO) is a low-intensity psychoeducational 6-week intervention delivered via mobile phones and assisted by a nurse for reducing depressive symptoms among individuals with diabetes or hypertension. CONEMO was tested in 3 pilot studies, 1 in São Paulo, Brazil, and 2 in Lima, Peru. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) at enrollment and at 6-week follow-up. Results: The 3 pilot studies included a total of 66 people. Most participants were females aged between 41 and 60 years. There was a reduction in depressive symptoms as measured by PHQ-9 in all pilot studies. In total, 58% (38/66) of the participants reached treatment success rate (PHQ-9 <10), with 62% (13/21) from São Paulo, 62% (13/21) from the first Lima pilot, and 50% (12/24) from the second Lima pilot study. The intervention, the app, and the support offered by the nurse and nurse assistants were well received by participants in both settings. Conclusions: The intervention was feasible in both settings. Clinical data suggested that CONEMO may help in decreasing participants’ depressive symptoms. The findings also indicated that it was possible to conduct RCTs in these settings.

  • Mental health apps provide a potential way to reduce symptoms and increase adherence by dispensing psychoeducation and therapeutic skills through an accessible electronic format.

    “Mental health apps provide a potential way to reduce symptoms and increase adherence by dispensing psychoeducation and other therapeutic skills through an electronic, easily accessible format [26-34].”

    From Examining the effectiveness of gamification in mental health apps for depression: Systematic review and meta-analysis (2021) · cites this paper as [28]

    The Introduction (Background) describes CONEMO as a mobile-phone psychoeducational intervention intended to reduce depressive symptoms, and the Methods (Emotional Control Intervention) describe its behavioral-activation and self-care content. But the Discussion (Principal Findings) reports that adherence to app sessions decreased over time; it does not establish that the app increased adherence. (LLM, conf=0.86)

  • Wider access to digital technology and mobile phones offers the possibility of delivering digital mental health interventions in a more scalable and convenient way.

    “In recent years, wider access to digital technology and mobile phones has presented new opportunities for overcoming these barriers, by offering the possibility of delivering digital mental health interventions in a more scalable and convenient way [10,11].”

    From Engagement and effectiveness of a healthy-coping intervention via chatbot for university students during the COVID-19 pandemic: Mixed methods proof-of-concept study (2021) · cites this paper as [11]

    The Introduction (Background; page not provided) says app-based care can simplify coordination and provide a more scalable process. The Abstract (Background; page not provided) says mobile phones are widely used in LMICs, and the Discussion (Principal Findings; page not provided) says participants found the app easy to use. The copy does not establish that access has widened in recent years or that digital delivery is more convenient than other approaches. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • There was a trend in all CONEMO pilot studies for a reduction in depressive symptoms over time.

    “However, there was a trend in all pilot studies for a reduction in depressive symptoms over time.”
  • Participants were satisfied with the CONEMO intervention.

    “and participants were satisfied with the intervention.”
  • The samples in the CONEMO pilot studies were small to test the efficacy of the intervention.

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.
