# Renaming of old routes

{% hint style="info" %}
This page is only relevant to users of previous versions of the 3di released before 2025, and can be ignored by new 3di users.
{% endhint %}

The system routes built in to the 3di have been renamed over the years. This page serves as a reference for users of previous versions of the 3di.

### 2022-2024 versions

<table><thead><tr><th width="223">Route name</th><th width="405">Description</th><th data-type="number"># questions</th></tr></thead><tbody><tr><td>ASD_brief<br>(DSM-5 Crit A+B)</td><td>Brief assessment for Autism Spectrum Disorder using DSM-5 criteria</td><td>66</td></tr><tr><td>ASD_extended<br>(DSM-5 Crit A+B)</td><td>Extended assessment for Autism Spectrum Disorder using DSM-5 criteria</td><td>177</td></tr><tr><td>ASD_brief<br>(ICD-10)</td><td>Brief assessment for Autism Spectrum Disorder using ICD-10 criteria (obsolete)</td><td>61</td></tr><tr><td>ASD_extended<br>(ICD-10)</td><td>Extended assessment for Autism Spectrum Disorder using ICD-10 criteria (obsolete)</td><td>134</td></tr></tbody></table>

Starting with 3di versions in 2023, the ASD\_brief and ASD\_extended routes come in two variants, one for each of the diagnostic criteria ICD-10 and DSM-5.

The new *ASD\_brief (DSM-5 Crit A+B)* route corresponds to the **DSM-5: ASD brief assessment** table in Word reports. The new *ASD\_extended (DSM-5 Crit A+B)* route corresponds to the **DSM-5: ASD extended assessment** table in Word reports.

The questions, routes and reporting tables for the ICD-10 criteria are present and unchanged from previous 3di versions, although the routes have been renamed to make the scoring criteria explicit: *ASD\_brief (ICD-10)* is the old *ASD\_brief*, and *ASD\_extended (ICD-10)* is the old *ASD\_extended*. The old reporting tables can still be generated, but you will have to [opt-in](/using-the-software/reports.md#including-dsm-4-scores) to include them in your reports. Note that according to UK guidelines the ICD-10 criteria are now considered to be superseded by DSM-5/ICD-11, and the the older routes are marked as obsolete.

The routes *ASD\_brief+DSM-5* and *ASD\_extended+DSM-5* have no equivalent in versions of the 3di from 2023 and later. Those routes combined questions from ICD-10 and DSM-5, which are now treated separately.

### 2021 version and before

<table><thead><tr><th width="221">Route name</th><th width="407">Description</th><th data-type="number"># questions</th></tr></thead><tbody><tr><td>ASD_brief</td><td>Brief assessment for Autism Spectrum Disorder using ICD-10 criteria</td><td>61</td></tr><tr><td>ASD_extended</td><td>Extended assessment for Autism Spectrum Disorder using ICD-10 criteria</td><td>134</td></tr><tr><td>ASD_brief+DSM-5</td><td>All questions from ASD_brief, plus all questions from the extended DSM-5 ASD assessment</td><td>184</td></tr><tr><td>ASD_extended+DSM-5</td><td>All questions from ASD_extended, plus all questions from the extended DSM-5 ASD assessment</td><td>193</td></tr></tbody></table>

The *ASD\_brief* and *ASD\_extended* routes are the basis of the table in Word reports named **Autism Spectrum Disorder subscales**, which applies ICD-10 scoring criteria.

* In the brief report – when you click the button *Report ASD\_brief* – the table draws on the 61 questions of the *ASD\_brief* route.
* In the full report – when you click the button *Report (with ASD\_extended)* – the table draws on the 134 questions of the *ASD\_extended* route.

There are also two longer route variants *+DSM-5* containing additional questions which enable the **DSM-5 scales for ASD** tables to be populated in the reports. Those tables apply the DSM-5 scoring criteria.
