Precision measurement for mental health & wellbeing
Computerised adaptive tests grounded in state-of-the-art Item Response Theory. Faster, more accurate, and more clinically meaningful than traditional questionnaires.
About the platform
Better measurements.
Better outcomes.
Traditional questionnaires ask every person every question, regardless of relevance. Our computerised adaptive tests select only the most informative items for each individual — delivering precise scores in far fewer questions.
Adaptive & Efficient
Each test adapts in real time to your responses. Only the most informative questions are presented, typically reducing administration time by 50–70% compared with static scales.
Psychometrically Rigorous
All item banks are calibrated using modern Item Response Theory, providing scores on an interval scale with known standard errors at every level of the trait continuum.
Clinically Validated
Cutpoints and norm tables are derived from representative population samples. Scores can be interpreted for screening, case identification, and progress monitoring.
Research-Backed
Item banks and scoring algorithms are grounded in peer-reviewed psychometric research, with full methodological documentation available for clinicians and researchers.
Suitable for All Settings
Designed for clinics, research studies, and self-guided assessment. No special training required — plain-language items accessible to adults at a broad range of literacy levels.
Comprehensive Coverage
Covering the full breadth of the HiTOP model — from broad psychopathology to specific disorders — enabling both screening and differential assessment within a unified framework.
Process
Simple to use,
sophisticated inside
Anyone can take a test in minutes. Behind the scenes, real-time IRT algorithms select optimal items and estimate scores with maximum precision.
Select an assessment
Choose from the full range of available tests using the HiTOP taxonomy diagram below. You can start broad (overall psychological distress) or go straight to a specific disorder of interest.
Answer questions at your own pace
Items are presented one at a time. Each answer updates the algorithm's estimate of your score and selects the single most informative next item. Most people complete a test in 3–7 minutes.
Receive your score instantly
At the end of the test you receive a score with a confidence interval, an interpretation relative to population norms, and (where applicable) a clinical screening result.
Share with your clinician or researcher
Results can be printed or saved as a PDF summary. If you are participating in a research study, your anonymised score can be submitted directly to the study platform.
Assessment Library
21 adaptive tests,
one framework
Every assessment is anchored within the Hierarchical Taxonomy of Psychopathology (HiTOP) — spanning from a general distress factor down to specific disorders across four clinical spectra. Begin broad and narrow in, or go straight to the condition you need.
- 4 clinical spectra: Fear, Distress, Substance Use, Disinhibition
- Spectrum-wide and specific disorder-level CATs
- Scores with confidence intervals and norm-referenced interpretation
- Average completion time 3–10 minutes per assessment
Evidence Base
Grounded in
published science
Every assessment has been developed and validated according to rigorous psychometric standards. Item banks are drawn from peer-reviewed literature and calibrated on large representative samples.
Item Response Theory
IRT models estimate latent trait levels and item parameters simultaneously, providing score estimates with known measurement error across the full trait range.
Computerised Adaptive Testing
CAT algorithms select the optimal next item at each step using maximum Fisher information, halting when a precision threshold is reached or the item bank is exhausted.
HiTOP Alignment
The Hierarchical Taxonomy of Psychopathology is an empirically derived dimensional model replacing categorical diagnoses with continuous spectra grounded in factor analytic research.
Population Norms
Scores are referenced against nationally representative normative data, enabling meaningful clinical interpretation and percentile comparison.
"The HiTOP model offers a comprehensive, empirically grounded alternative to traditional nosologies, organising psychopathology from narrow symptoms to broad spectra within a unified dimensional framework."
"Computerised adaptive testing reduces administration burden by 50–75% while maintaining or improving measurement precision compared with full-length static instruments."
"IRT-based scoring provides estimates with known standard errors, enabling clinicians to quantify measurement uncertainty and set appropriate confidence thresholds."
These assessments are designed for screening and research purposes only. They are not diagnostic tools and do not replace clinical assessment by a qualified mental health professional.
