A new PLOS One study protocol (published 16 July 2026) proposes a mixed-methods quality-improvement intervention for School-Based Support Teams (SBSTs) in Gauteng secondary schools. For researchers and program teams doing qualitative analysis of school-based support teams, the payoff is clear: learn how to turn PHQ‑A/GAD‑7/ITQ‑CA interview transcripts and survey data into prioritized, actionable themes that directly shape interventions. This post refracts the protocol through AI-enabled qualitative research workflows and shows concrete ways to reproduce the study’s coding, triangulation, and cross-segment analysis faster and more reproducibly using Evidano (www.evidano.com). You’ll get a quick snapshot of the study inputs, a practical two-week pilot checklist, and specific Evidano features to map to each research step: transcription, translation, codebook, thematic and cross-segment analysis, and visual reports.
Key Takeaways
AI accelerates qualitative analysis of school-based support teams by compressing manual transcription, coding, and triangulation into days while preserving rigor and traceability.
Evidano is an AI-powered qualitative data analysis platform that ingests transcripts and survey CSVs, automates transcription and coding, supports codebook workflows, and links thematic outputs to survey scores.
- The protocol (PLOS One, 16 July 2026) develops and pilots a SBST quality-improvement intervention for adolescents aged 13–19 across four Gauteng secondary schools using a sequential explanatory mixed-methods design.
- Quantitative sample is n = 440 (cross-sectional survey) and qualitative interviews are approximately 20 SBST members, with Phase 2 targeting a post sample of ≈206.
- Evidano maps to the protocol by ingesting CSVs and transcripts, applying PII redaction and custom transcription dictionaries, running auto-coding with codebook import/export, and producing cross-segment frequency and co-occurrence analyses.
Fast take and source
The fast take: Dyani et al. (PLOS One, 16 July 2026) publish a protocol to develop and pilot a SBST quality-improvement intervention for adolescents aged 13–19 in four Gauteng secondary schools.
- Original protocol: PLOS One
- Why it matters: School settings are high-impact sites for early mental-health intervention; the protocol combines prevalence measurement, a scoping review, interviews, and a pre-post pilot.

What the study does (methods in plain English)
The study protocol runs two phases: Phase 1 measures prevalence and associated factors via a cross-sectional survey (n=440) and a scoping review, then conducts in-depth interviews with SBST members (~20) using a descriptive phenomenological design and Colaizzi’s seven-step analysis; Phase 2 uses Phase 1 evidence to co-develop, pilot, and evaluate a SBST quality-improvement intervention with a pre-post quasi-experimental design (target post sample ≈206).
- Sampling: Four purposive schools (2 urban, 2 township), stratified random sampling for learners, purposive sampling for SBST members.
- Quant analysis: SPSS v30, t-tests, chi-square, multivariable regression, ANOVA, and clustering accounted for with mixed-effects or robust standard errors.
- Qual analysis: Colaizzi framework supported by NVIVO 15; interviews audio-recorded with consent and transcribed.
- Ethics: SMUREC approval; parental consent plus adolescent assent; on-site mental health support available.
So what for researchers, UX/education teams and policy analysts
For qualitative researchers
Qualitative researchers should use the protocol as an example of triangulation, where prevalence surveys guide interview sampling and intervention design.
Key reproducible practices in the protocol include validated instruments (PHQ‑A, GAD‑7, ITQ‑CA), pretesting (n=20), independent dual extraction for the scoping review, and transparent codebook development using Colaizzi.
For school/program teams & UX researchers
School and UX researchers should use mixed evidence (survey frequencies plus lived-experience quotes) to prioritize intervention components.
The study’s focus on SBST capacity-building aligns with iterative user-testing: pilot, measure pre-post outcomes, and refine structure and referral workflows.
For policy and monitoring teams
Policy and monitoring teams should adopt the protocol’s measurable endpoints and replicable sampling frame for district-level scale-up decisions.
The protocol provides depression, anxiety, and trauma score endpoints that can be integrated with education and health reporting.
Do more, faster with Evidano (mapping features to the protocol)
Ingest & clean mixed inputs
Evidano ingests CSVs, interview transcripts, PDFs, and scraped web content and applies PII redaction and a custom transcription dictionary to preserve local terms and school names.
The protocol’s problem of handling survey spreadsheets, interview audio, and scoping-review PDFs maps to Evidano’s ingestion and redaction features.
Reproduce Colaizzi + NVIVO workflows
Evidano supports codebook import/export, AI-assisted coding, and hierarchical code visualizations to speed Colaizzi-aligned steps while keeping participant quotes for validation.
The protocol’s manual coding in NVIVO can be accelerated by Evidano’s auto-coding and codebook validation workflow and then validated against transcripts.
Triangulate surveys with themes
Evidano links prevalence outputs to qualitative themes by running cross-segment analysis that shows which themes co-occur with high PHQ‑A and GAD‑7 scores.
The protocol’s manual linking of SPSS outputs to qualitative themes is addressed by Evidano’s frequency tables and co-occurrence networks for stakeholder reports.
Pilot-ready outputs & secure handling
Evidano encrypts data end-to-end, does not use client data to train third-party models, and produces ready-to-share visuals and exportable reports for ethics boards and departments of education.
The protocol’s requirement to handle sensitive transcripts aligns with Evidano’s PII redaction and secure export features.
Start quickly
Evidano lets teams drop transcripts and survey CSVs, map columns (age, grade, school), run auto-theming, validate auto-codes on a 10–20% sample, and run cross-segment analyses to inform intervention design.
The protocol’s practical workflow from transcription to cross-segment analysis can be initiated immediately by following Evidano’s mapping and auto-theming steps.
Two-week pilot checklist: from raw data to intervention-ready themes
The two-week pilot checklist shows practical steps to reproduce the protocol’s Phase 1 insights in a compressed pilot.
- Day 1–2: Ingest survey CSVs and interview audio; run automatic transcription with a custom dictionary and PII redaction.
- Day 3–4: Auto-code transcripts and run initial theme extraction; import a validated codebook (Colaizzi-aligned) or create one in Evidano.
- Day 5–7: Link survey variables (PHQ‑A, GAD‑7, ITQ‑CA scores) to respondent IDs and run cross-segment frequency analysis (by school, grade, sex).
- Day 8–10: Validate auto-codes on a purposive 10–20% sample, refine code hierarchy, and generate a co-occurrence network and top quotes per theme.
- Day 11–12: Draft intervention priorities mapped to high-frequency themes and high-risk segments, for example high PHQ‑A plus trauma exposure.
- Day 13–14: Export visuals and an executive brief for SBSTs and district stakeholders and set follow-up metrics for the pre-post pilot.
Ethics note
The protocol involves sensitive adolescent mental-health data and analyses are intended for research and program design only, not for diagnosis.
The protocol requires SMUREC approval, parental consent and adolescent assent, on-site mental-health support, anonymized outputs, and secure handling of transcripts; Evidano’s PII redaction and encryption align with these safeguards.
FAQ: Qualitative analysis of school-based support teams

How do I run a compressed two-week pilot based on the protocol?
A compressed two-week pilot follows a structured ingest-to-report flow: ingest, auto-transcribe, auto-code, link survey scores, validate codes on 10–20% of samples, and export visuals and briefs.
The day-by-day checklist in this post mirrors the protocol’s Phase 1 steps and is designed to produce intervention-ready themes and stakeholder-ready reports within 14 days.
