Evidence · Programme
The evidence developed across successive phases: item development and feasibility, psychometric validation, clinical and multicentre comparison, and continuing real-world evaluation.
The programme is described as a pathway; study versions and overlapping datasets remain carefully distinguished.
Programme pathway
The validation programme is best understood as a sequence rather than a single event. Internal evidence summaries describe early item development and feasibility work, formal psychometric analysis, clinical comparison, multicentre evaluation, and continuing platform-level research.
Some chronology and instrument-version questions remain under archive reconciliation. The public site therefore presents the pathway without merging every study into one total or implying that every phase used an identical scale.
Phase I
Items were developed from literature, diagnostic frameworks, suicide-prevention concepts, positive psychology, and expert consultation. Early work examined clarity, cultural relevance, acceptability, completion, and the feasibility of digital administration in educational settings.
Phase II
Published development work reports item analysis, internal-consistency testing, and exploratory and confirmatory factor analysis. Later internal documents describe further refinement of symptom and risk components.
Phase III
Subsequent research compared digital classifications with clinician-led psychiatric assessment and examined risk staging across multiple sites. The purpose was to evaluate screening and referral-support performance—not to convert the tool into an autonomous diagnostic system.
Continuing programme
Future work can examine usability, acceptability, referral completion, safety, wellness engagement, institutional feasibility, and longitudinal outcomes within the full RELIEF PLUS pathway.
