Key Takeaways
Evidano is an AI-powered qualitative data analysis platform that helps teams move from raw transcripts and home videos to thematic, cross-segment insights in hours not weeks.
A 2024 qualitative study of 19 South Korean preschoolers shows screens often catalyze offline play, sibling spillover shapes media diets, and qualitative methods surface design and policy levers that minutes-only statistics miss.
- The study sample was n = 19 children, ages 3–5, from four early childhood centres in 2024, with multimodal data including play sessions, parent interviews, and short home videos.
- Screens frequently act as catalysts for offline making, role-play, and co-play, while study-first app flows and sibling spillover gate access to fun.
- Researchers and product teams should code for interaction types and transition triggers, and policy teams should use cross-segment qualitative analysis to identify infrastructure needs.
Fast take: qualitative analysis of digital childhood
The fast take: a 2024 qualitative study of 19 South Korean children (ages 3–5) and their parents found that screens often catalyze offline play, that study-first app flows gate access to fun, and that sibling spillover and multilingual households shape media diets in ways statistics miss.

|---|---|---|
| Device uptake | 70% of infants/toddlers use smart devices before age 3 | Korean statistic cited in study (LSE Blogs) |
| Average first smartphone | 3.6 years | National estimate cited in study (LSE Blogs) |
| Daily media use (age 3–9) | Over 3 hours/day on average | Contextual stat cited in study (LSE Blogs) |
| Study sample | n = 19 children; ages 3–5; 2024; 4 early childhood centres | Primary qualitative dataset (play sessions, parent interviews, short home videos) |
| Sibling prevalence | 12 of 19 children had older siblings influencing media choices | Key mechanism: sibling spillover |
What the study did (methods & ethics)
The methods: researchers ran play-based group sessions with children ages 3–5, conducted individual parent interviews, and collected short home video clips of media use across four early childhood centres in 2024.
The study emphasises observation of practice, researchers observed how screens feed into crafts, acting, and co-play rather than counting minutes alone.
Ethics note: the original research is qualitative and non-diagnostic, and any secondary analysis should maintain consent, child-protective handling of media, and avoid clinical claims.
Implications for researchers, UX teams, and policy analysts
UX & Product Researchers
UX and product researchers should not treat screen-time as a single metric.
Researchers should code interactions where screens trigger offline making, role-play, or cross-device routines to surface design opportunities such as co-viewing modes and sibling-aware profiles.
Researchers should look for transition triggers in transcripts and video, for example countdown timers or Bluetooth microphones, and tag them as interaction affordances in the codebook.
Policy & Early‑Years Researchers
Policy and early-years researchers should not rely on minutes alone to understand media use.
Policy teams should translate parent narratives into actionable levers, for example community spaces, evidence-based guidance at childcare centres, and targeted support for multilingual families.
Policy prioritisation should use qualitative cross-segment analysis across single parents, immigrant households, and sibling-gap households to identify infrastructure deficits such as affordable indoor play spaces.
Qualitative teams scaling insights
Qualitative teams scaling insights should capture multimodal data and link units of analysis.
Teams should capture audio transcripts, short home videos, and parental surveys and link units of analysis (child, household, session) to run cross-segment comparisons such as immigrant versus non-immigrant households.
Teams should validate child-centered inferences by triangulating child play transcripts with parental explanations and short video clips.
Do more, faster with Evidano
Problem: fragmented multimodal inputs
Multimodal inputs create fragmentation, researchers juggle transcripts, interview audio, parent surveys, and short home videos often in multiple languages.
Evidano solution: unified ingestion + secure processing
Evidano ingests transcripts, interview audio, video captions, and survey CSVs into one workspace for consistent analysis.
Evidano provides transcription with custom dictionaries and PII redaction and translation so multilingual clips (Korean, Chinese, English) are analyzed consistently.
Evidano encrypts all data and never uses research data to train third-party models, a critical safeguard for child-related research.
Problem: hand-coding bottlenecks
Hand-coding hundreds of clips and transcripts creates a bottleneck, manual coding is slow and inconsistent across coders.
Evidano solution: AI-assisted thematic + cross-segment analysis
Evidano auto-generates themes, frequency counts, and co-occurrence networks from transcripts, then supports human-in-the-loop codebook import.
Evidano enables cross-segment comparisons in a click, for example households with or without older siblings and immigrant versus non-immigrant households.
Evidano provides an AI chat over documents to surface child-perspective quotes, extract transition triggers, or compile a stakeholder-ready evidence brief.
Problem: stakeholder handoffs
Stakeholder handoffs fail when outputs are not concise and verifiable.
Evidano solution: visuals & shareable reports
Evidano produces word clouds, hierarchical theme to subcode trees, and co-occurrence networks that make central claims visible and defensible for stakeholders.
Evidano helps stakeholders see study claims such as the learning-gates-play loop and sibling spillover through shareable visuals and reports.
Checklist: 7-step workflow to reproduce these insights
This checklist lists a seven-step workflow to reproduce the study’s insights.
1. Gather multimodal inputs: audio interviews (parents), play-session recordings, short home videos, and a one-page demographic survey.
2. Transcribe and translate in Evidano with a custom dictionary for local terms and character names (e.g., Teenieping). Enable PII redaction for child data.
3. Import an initial codebook (play, study-first flows, sibling spillover, multilingual use, parent negotiation) and run AI-assisted auto-coding.
4. Review automated themes, refine with human coders, and lock hierarchical codes to subcodes.
5. Run frequency and cross-segment analyses, for example single parents versus dual caregivers and households with older siblings.
6. Generate visuals such as a co-occurrence network of 'screen triggers' and 'offline play outcomes' and extract representative quotes.
7. Produce a short stakeholder brief and a reproducible dataset export for policy teams or product designers.
FAQ: qualitative analysis of digital childhood
