Traits similar to those shown in
spectrum condition (ASC) are apparent in relatives of individuals with ASC, and in the general population without necessarily meeting diagnostic criteria for an ASC.
We assess whether the -Spectrum Quotient (AQ), a self-report measure, has hierarchical properties using Mokken scaling.
Hierarchical scales allow the presence of a latent trait to be identified by discovering whether and how many specific items form an ordered array along it.
Data were collected from 2 groups: (1) people with ASC (n = 449: 240 males, 209 females, M(age) 35.4 years, SD = 12.8) and (2) university students (n = 943: 465 males, 475 females, M(age) = 23.0 years, SD = 8.4).
A single Mokken scale was obtained in the data from university students and 3 scales were obtained in the data from people with ASC.
The scales all showed moderate Mokken scaling properties with the single scale obtained from university students showing weak invariant item ordering and 2 of the scales from people with ASC showing weak invariant item ordering.
The AQ formed reliable Mokken scales.
There was a large overlap between the scale from the university student sample and the sample with ASC, with the first scale, relating to social interaction, being almost identical.
The present study confirms the utility of the AQ as a single instrument that can dimensionalize autistic traits in both university student and clinical samples of ASC, and confirms that items of the AQ are consistently ordered relative to one another.

There is substantial previous research which suggests alignment, or co-ordination, on many
levels between two partners in a dialogue. This report examines alignment in language in
relation to participants& scores on the Autism-Spectrum Quotient, a questionnaire which
indicates degrees of autistic traits. We report an experiment investigating two language tasks,
using a confederate scripting design, in order to determine if score on the AQ affected
participants& alignment. We found that score on the AQ had a significant effect on lexical
alignment, with participants who scored highly aligning less with a partner. A marginal effect,
which was just below significance, was found between the AQ and alignment on the syntactic
task, which suggests that in this task participants who scored highly on the AQ also aligned less
syntactically. From these results we conclude that alignment in language is governed by a
mediated account and that participants in a dialogue take beliefs about a partner into account
when choosing which language to use. We specifically promote a social affect theory behind
alignment, with participants choosing words in order to be socially appropriate and to increase
positive feeling between them and their partner.
