SDQplus for maximum clinical, epidemiological and managerial benefit from your SDQs

SDQplus is a web-based application to facilitate longitudinal mental health assessment of individual young people (and adults). The main features are:

  • Introduction of a persistent individual identification (PlusIID) for the person who is the subject of multiple assessments.

  • Uses the familiar, paper-based SDQscore for longitudinal assessment around the PlusIID.

  • Self-entry of SDQ assessments on PCs, laptops, iPads and mobile phones. Invitations may be sent via email for the person, parents and teachers to complete. Dansk, Deutsch, English, Español, Français, Hrvatski, Italiano, Nederlands, Norsk, Português, Русский and Svenska are supported.

  • Access to in-depth DAWBA psychiatric diagnostic instruments ( via the PlusIID. DAWBA assessments may be done longitudinally.

  • Integration of the data from all assessments and diagnoses into a single summary “visualisation”, ordered chronologically.

  • Availability of applications to support clinical/counseling interactions with individual children and young people; e.g., AI expert system to suggest lines of inquiry, trajectory plotting, incidence prediction and Internalisation/Externalisation analysis. See an example.

  • A full range of APIs to allow organisations to integrate SDQplus into their systems (EHR, CMS, SMS).

The closely related web browser application SDQblockchain  allows using SDQplus for cohorts of individuals (e.g., groups, class of students, client or patient list). Once set up, this application can save up to 75% of your time conducting SDQ assessments and greatly facilitate data export of assessments. SDQblockchain allows secure linking of SDQ data to your client/patient IDs to allow integration with your data.

Each member of your cohort is linked to an SDQ ID (the PlusIID). This PlusIID link allows combining and exporting your organisation's demographics and other information with your SDQ assessments. SDQblockchain uses strong encryption and proven blockchain technology to allow your data to be saved on our servers while observing the "data protection by design" principle.

There are no additional charges for using the SDQplus or SDQblockchain applications. You can use the paper-based SDQscore with SDQplus and there is no increase in your fees for assessments; your experience within the SDQscore assessment and scoring application is unchanged. The new self-entered assessments of SDQplus each cost US$1.00, but are email-able and provide much better reports (PDF included) and software tools in the fee. Considerable professional staff effort is saved with self-entry (e.g., 90%) and we have consistent, reliable reports of teachers assessing over 100 students an hour via SDQblockchain.

Session by Session (SxS) is another web browser application (“app”) that allows you to monitor individual patient progress via SDQplus. Progress is linked robustly and reliably to all other measures supported by SDQplus. SxS costs only US$0.10 (ten cents) per assessment and provides immediate graphical visualisation of the progress of your patients.


The web browser application SDQcohort  allowed using SDQplus for cohorts of individuals (e.g., groups, class of students, client or patient list).  SDQcohort achieved DPA/GDPR compliance through strong encryption and local storage on your own computer (when you may not use SDQblockchain). This application has been replaced by SDQblockchain.


Is a web browser application (“app”) that allows you to maintain a patient/client list with personal details on your own computer. Your patient/client details are robustly and reliably linked toSDQplus, without causing data protection concerns. MySDQ also is a convenient way to use SDQplus in the absence of an integrated electronic health record (EHR) or client management system (CMS). MySDQ has been replaced by SDQblockchain and further development is not anticipated. If you are on MySDQ and want to move to SDQblockchain, we can help you! CONTACT US
