Abstract
LAY 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 Its assessment has been performed through outdated broad autism phenotype/autism spectrum disorder definitions and tests.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.

Abstract
LAY ABSTRACT Sensory symptoms are a major source of distress for many autistic people, causing anxiety, stress, and avoidance. Sensory problems are thought to be passed on genetically together with other autistic characteristics, such as social preferences. This means that people who report cognitive rigidity and autistic-like social function are more likely to suffer from sensory issues. We do not know what role the individual senses, such as vision, hearing, smell, or touch, play in this relationship, because sensory processing is generally measured with questionnaires that target general, multisensory issues. This study aimed to investigate the individual importance of the different senses (vision, hearing, touch, smell, taste, balance, and proprioception) in the correlation with autistic traits. To ensure the results were replicable, we repeated the experiment in two large groups of adults. The first group contained 40% autistic participants, whereas the second group resembled the general population. We found that problems with auditory processing were more strongly predictive of general autistic characteristics than were problems with the other senses. Problems with touch were specifically related to differences in social interaction, such as avoiding social settings. We also found a specific relationship between proprioceptive differences and autistic-like communication preferences. The sensory questionnaire had limited reliability, so our results may underestimate the contribution of some senses. With that reservation in mind, we conclude that auditory differences are dominant over other modalities in predicting genetically based autistic traits and may therefore be of special interest for further genetic and neurobiological studies.

Abstract
AbstractThe broad autism phenotype (BAP) represents the elevated but nonclinical levels of autism-related expressions expanding them beyond the disorder threshold towards the general population and it is assessed worldwide using the Broad Autism Phenotype Questionnaire. In this study, we applied a Rasch item response approach to the Spanish and the English BAPQ versions. This approach allows us to test the proper functioning of each version, estimate which BAP behaviours are more likeable at different levels of severity, and study whether BAPQ item’s severities and orders could be considered equivalent between both versions. A Spanish community sample of 970 participants and an English of 533 ones completed either the Spanish or the English version of the BAPQ. The results revealed a lack of unidimensionality of the Pragmatic Language subscale in both tests and the Rigid subscale in the English version. Both Aloof subscale versions and the Spanish Rigid demonstrated adequate properties but with several items showing differential functioning in the case of Aloof. We conclude by highlighting the necessity of BAP measurements paralleling the current autism spectrum disorder structure, following the severity-dimensional conceptualization (behaviours are continuously distributed according to their severity), and suitable for being adapted to different languages.

Abstract
We validated a Korean version of the Broad Autism Phenotype Questionnaire (BAPQ) by investigating its factor structure with a nonclinical sample. Participants were 495 undergraduate students in Korea. The results show that the Korean version of the BAPQ (K-BAPQ) had adequate internal
consistency (Cronbach's α = .75–.89). Correlations between scores on the BAPQ and on the Autism-Spectrum Quotient were statistically significant and moderate-to-high in size. Confirmatory factor analysis did not show a satisfactory fit with the factor structure of the original
BAPQ. Exploratory factor analysis demonstrated that a three-factor structure could be suitable in our sample, but the internal structure of the BAPQ still needs further examination. We recommend use of the total score of the K-BAPQ, as opposed to those of the subscales alone, and suggest that
further research is needed to confirm the factor structure.

Abstract
The broad autism phenotype (BAP) is a set of characteristics often observed in typically developing people with a genetic load for autism, such as parents of autistic children. The Broad Autism Phenotypic Questionnaire (BAPQ) is a 36-item questionnaire developed to identify the BAP in first-degree relatives of autistic people. We translated the BAPQ into Swedish and examined its psychometric properties in a Swedish sample consisting of 45 parents of children with ASC and 74 parents of non-autistic children. We found support for the original 3-factor structure (aloof, pragmatic language and rigid), good internal consistency and convergent validity with the Autism Quotient. Thus, the Swedish BAPQ exhibits acceptable psychometric properties and may be useful for assessing the BAP in non-clinical populations.

Abstract
Purpose
Considering the high comorbidity of autism spectrum disorder (ASD) with externalizing disorders and that ASD is considered as a continuum, which implies the identification of it features in the whole population, the purpose of this paper is to know the characteristics of the association of externalizing symptoms in the population with ASD traits.
Design/methodology/approach
One hundred and seventeen postsecondary students participated in the study, providing responses to a battery of self-reported tests.
Findings
The existence of a significant association between ASD and attention deficit hyperactivity disorder (ADHD) (0.519; p < 0.01) was proved. Regression analyses showed that problems in executive functioning, working memory deficits and difficulties in the use of emotion regulation strategies predicted the presence of ADHD traits (F = 36.757, R2 = 62.3%, p < 0. 01) and impulsivity behavior (F = 18.249, R2 = 45.1%, p < 0.01).
Research limitations/implications
Externalizing symptomatology in people with higher ASD traits is extended to the general population. Future research should study other problematic behaviors, such as aggression or self-harm, to continue generating appropriate interventions.
Originality/value
The results reported reinforce the study of ASD as a dimensional disorder, in line with the latest advances in the classification of psychopathology. Considering which variables are behind the problematic behaviors allows interventions to be focused on these factors, contributing to their reduction and to the improvement of professional practices.

Abstract
Although, the operationalization of the autism spectrum disorder has been updated around two domains, the broad autism phenotype (BAP) one has not. Additionally, the items of the three common BAP measures, the Broad Autism Phenotype Questionnaire (BAPQ), the Autism Quotient, and the Social Responsiveness Scale (SRS), remain organized around a non-consensual number of factors. We explored whether the items of these measures matched with the two-domain operationalization through a parallel analysis, which has suggested two main components, and two expert judgments which have assessed item wording, relevance, and construct representativeness. A remaining pool of 48 BAP-relevant items suggested a possible under-representation of two subdomains. Despite the relevance of all the BAPQ items, only the SRS ones tapped in all subdomains.

Abstract
Broad Autism Phenotype (BAP) refers to a set of symptoms or personality traits which similar but not meet the diagnostic criteria for autism in relatives of individuals with Autism Spetrum Disorders (ASD).The Broad Autism Phenotype Questionnaire (BAPQ) is one of the new and widely used assessment tools to measure BAP.It has been translated into 8 different languages and some versions were investigated the psychometric properties but not including Chinese version (BAPQ-C).This study aimed to analyze the reliability and validity of the BAPQ-C and explore its applicability in the Chinese population. 1,618 families were included in the study consisting of 890 ASD children and 728 typically developed(TD)children. Our results did not find a well-fitting three-factor(Aloof,Rigid,Pragmatic language) structure which is consistent with previous studies.But we formed a model that only included Aloof and Pragmatic language dimensions.The parameter after removing the rigid dimension was significantly better.This study indicated that the short version of Aloof and Pragmatic language sub-scales has good reliability and validity and can be used to study BAP in the Chinese population. Nevertheless, more studies are still needed to improve the psychometric properties of the BAPQ-C.
