Thirty years after political transition, South Africa still records the highest income‑inequality worldwide (Gini ≈ 0.63) (Harmse, 2014). Chronic socio‑economic adversity exposes the average South African to elevated trauma, social stressors and psychological distress (Harriman et al., 2021). Marginalised groups suffer disproportionately, yet qualified mental‑health professionals remain scarce—only 0.97 public‑sector psychologists and 0.31 psychiatrists per 100 000 uninsured citizens are available country‑wide.

The term “The Mental‑Health Gap” coined by Burns (2011) reflects service models optimised for high‑income, urban populations capable of paying out‑of‑pocket fees (Bantjes & colleagues, 2016). In contrast, digital connectivity has expanded rapidly (where approximately 45.34 million South Africans or 74.7 % of the South African population) had access to the internet in January 2024, with median mobile speeds of ≈ 50 Mbps. These conditions invite scalable, low‑cost e‑health solutions.

Web‑based psychometric platforms (e.g., Psychtoolbox.org, Millisecond Inquisit, Sapien Industry) can deliver cognitive tests, symptom screeners and other interventions via browser or smartphone. A 2023 meta‑analysis of 36 Randomized Controlled Trials (RCTs) showed that digital interventions reduced depression and anxiety in LMICs (g= 0.45) echoed by the Journal of Medical Internet Research (JMIR, 2023).

The COVID‑19 pandemic accelerated telepsychology uptake; 85 % of surveyed South‑African psychologists offered remote services in 2020–2023, rating the experience largely positive, though public‑sector providers faced connectivity and training barriers updated HPCSA telehealth guidelines (2021) now legitimise such practice, setting an ethical frame for further innovation.

Conventional, clinic‑based mental‑health care cannot reach most low‑income or rural communities under the current workforce constraints. Travel costs, language mismatch, appointment backlogs and stigma further widen the service gap. Without disruptive delivery models South Africa and other LMICs broadly—risk entrenching cycles of untreated psychological morbidity that undermine education, employment and public health.

Psychometric web‑applications are promising but untested at scale in LMICs. Key uncertainties include:

1. Reliable internet
2. Device access
3. Digital literacy
4. Language localisation
5. Data security
6. Informed consent online
7. Clinical governance for unsupervised or semi‑supervised use.

1. Conduct a scoping review (2000‑2025) of digital cognitive assessments and web‑based psychological interventions employed in LMICs, extracting evidence on validity, reliability, clinical outcomes and cost‑effectiveness.
2. Implement a pilot web study in South Africa using Sapien Industry to
   1. Administer a standard survey about perceptions towards remote occupation.
   2. Deliver two cognitive tasks, namely:
      1. Visual Reaction Task
      2. Stop Signal Task

   Typical psychometric properties (completion rate, internal consistency, test–retest stability) will be analysed after the implementation of these tests.

3. Identify technological, ethical and contextual facilitators/barriers via mixed‑methods interviews with participants and practising psychologists, informing an implementation framework for deployment of such methods in LMICs.

1. Can core psychological activities (clinical screening, cognitive assessment, brief intervention) be delivered validly through web‑applications in LMIC contexts, while maintaining the core tennets of valid psychometric research?
2. What are the pertinent use cases of psychometric web-applications in LMICs like South Africa?
3. How might such tools attenuate the mental‑health gap in South Africa and comparable LMICs?
4. What technical, ethical and sociocultural threats should be noted in the discussion of the large‑scale deployment of web‑based psychometry.

The study provides first‑hand empirical evidence of the practicality of webb‑based assessments in a middle‑income African setting, complimenting global findings that digital tools can improve common intervention in LMICs  Policymakers will gain a context‑specific roadmap outlining infrastructural needs, localisation requirements and ethical guidelines to implentation. Outputs will include:

• A peer‑reviewed article from an open‑access journal (e.g., Global Mental Health)
• A technical manual for clinicians on integrating validated web‑applications into stepped‑care models
• Policy briefs aligning findings with the National Digital Health Strategy (2024‑2030).
