Preliminary evaluation of a culturally adapted CBT-based online programme for depression and anxiety from a lower middle-income country

Digital interventions for common mental disorders in low- and middle-income countries: A systematic review and meta-analysis

Background

In low-resource settings, e-mental health may substantially increase access to evidence-based interventions for common mental disorders. We conducted a systematic literature search to identify randomised trials examining the effects of digital interventions with or without therapeutic guidance compared to control conditions in individuals with anxiety and/or depression symptoms in low- and middle-income countries (LMICs).

Methods

The main outcome was the reduction in symptoms at the post-test. Secondary outcomes included improvements in quality of life and longer-term effects (≥20 weeks post-randomisation). The effect size Hedges' g was calculated using the random effects model.

Results

A total of 21 studies (23 comparisons) with 5.296 participants were included. Digital interventions were more effective than controls in reducing symptoms of common mental disorders at the post-test (g = -0.89, 95% confidence interval [CI] -1.26 to -0.52, p < 0.001; NNT = 2.91). These significant effects were confirmed when examining depressive (g = -0.77, 95% CI -1.11; -0.44) and anxiety symptoms separately (g = -1.02, 95% CI -1.53 to -0.52) and across all other sensitivity analyses. Digital interventions also resulted in a small but significant effect in improving quality of life (g = 0.32, 95% CI 0.19 to 0.45) at the post-test. Over the longer term, the effects were smaller but remained significant for all examined outcomes. Heterogeneity was moderate to high in all analyses. Subgroup and meta-regression analyses did not result in significant outcomes in any of the examined variables (e.g., guided vs. unguided interventions).

Conclusions

Digital interventions, with or without guidance, may effectively bridge the gap between treatment supply and demand in LMICs. Nevertheless, more studies are needed to draw firm conclusions regarding the magnitude of the effects of digital interventions.

Experiences and Perceptions of Telephone-delivery of the Common Elements Treatment Approach for Mental Health Needs Among Young People in Zambia During the COVID-19 Pandemic

Background

Mental and behavioral health needs are immense in low-to-middle income countries (LMIC), particularly for adolescents and young adults (AYA). However, access to mental health services is limited in LMIC due to barriers such as distance to a health care site, low number of providers, and other structural and logistical challenges. During the COVID-19 pandemic, these barriers were significantly exacerbated and, thus, mental health services were severely disrupted. A potential solution to some of these barriers is remote delivery of such services via technology. Exploration of AYA experiences is needed to understand the benefits and challenges when shifting to remotely delivered services.

Methods

Participants included 16 AYA (15-29 years) residing in Lusaka, Zambia who met criteria for a mental or behavioral health concern and received telehealth delivery of the Common Elements Treatment Approach (CETA). AYA participated in semi-structured qualitative interviews to explore feasibility, acceptability, and barriers to telephone-delivered treatment in this context. Thematic coding analysis was conducted to identify key themes.

Findings

Three major response themes emerged: 1) Advantages of telehealth delivery of CETA, Disadvantages or barriers to telehealth delivery of CETA, 3) AYA recommendations for optimizing telehealth (ways to improve telehealth delivery in Zambia. Results indicate that logistical and sociocultural barriers i.e., providing AYA with phones to use for sessions, facilitating one face-to-face meeting with providers) need to be addressed for success of remotely delivered services.

Conclusion

AYA in this sample reported telehealth delivery reduces some access barriers to engaging in mental health care provision in Zambia. Addressing logistical and sociocultural challenges identified in this study will optimize feasibility of telehealth delivery and will support the integration of virtual mental health services in the Zambian health system.
