The Broad Autism Phenotype-International Test (BAP-IT): A two-domain-based test for the assessment of the broad autism phenotype.

Godoy-Giménez et al. (2024) · Autism : the international journal of research and practice 2024
★ The Verdict

The 20-item BAP-IT gives you a rapid, two-domain screen for broad autism traits in English or Spanish.

✓ Read this if BCBAs who screen adults for autism traits in bilingual clinics or research.
✗ Skip if Clinicians only working with diagnosed children who need full diagnostic tools.

01Research in Context

01

What this study did

Godoy-Giménez et al. (2024) built a new 20-item screen called the BAP-IT. It checks for broad autism traits in two quick domains.

The team tested it in both Spanish and English speaking adults. They wanted a faster way to spot the broad autism phenotype.

02

What they found

The BAP-IT held up well in both languages. It gave a brief yet solid picture of broad autism traits.

The two-domain format kept the tool short without losing key info.

03

How this fits with other research

Godoy-Giménez et al. (2018) showed the older Spanish BAPQ had weak items in its Pragmatic Language sub-scale. The new BAP-IT drops that problem area and trims the count to 20.

Ingersoll et al. (2011) told clinicians to pick SRS-A or BAPQ over the AQ. The BAP-IT now gives an even shorter option while keeping the good parts.

Mace et al. (1990) and Lord et al. (1997) built other 20-item autism scales for diagnosed behaviors. BAP-IT updates the idea for the broad autism phenotype in the general public.

04

Why it matters

You now have a 20-item tool that works in English or Spanish and takes minutes to give. Use it during intake to flag broad autism traits before a deeper evaluation. If you already use the BAPQ, try the BAP-IT for quicker screening and skip the weak language items.

03Original abstract

The broad autism phenotype refers to a group of behaviors related to autism spectrum disorder, but that appear to a lesser extent. Its assessment has been performed through outdated broad autism phenotype/autism spectrum disorder definitions and tests. To address this problem, this study presents the development of a new test, the Broad Autism Phenotype-International Test, a 20-item measure consisting of two dimensions, SOCIAL-BAP and RIRE-BAP, targeting the two-domain operationalization of autism spectrum disorder in Spain and the United Kingdom. Unlike the Broad Autism Phenotype Questionnaire, this test received empirical support as a quick and effective broad autism phenotype measure that can facilitate both broad autism phenotype/autism spectrum disorder research and interventions. This is the first step to studying the BAP in several Spanish and English-speaking countries.
