Autism Phenotype

Broad Autism Phenotype (BAP) represents a group of personality traits expressed in limitations in social relations and pragmatic speech dimension, and rigid behavior. The Broad Autism Phenotype Questionnaire (BAPQ) measures personality traits which are crucial in defining the BAP. In the present research, three studies were conducted with the general aim to create a short form of the BAPQ. Study 1 was carried out to determine the factor structure of the BAPQ in a sample of 501 students and to select items for the short form. Obtained components: Aloofness, Rigidity, and Pragmatics, corresponding to the structure of the instrument proposed by authors, accounted for 26.61% of variance. Study 2 was conducted to examine factor structure of the BAPQ short form (BAPQ-SF), in a sample of 298 students. This solution explained 45.76% of the total variance. The aim of Study 3 was to determine psychometric characteristics of the BAPQ-SF in a sample of students (N = 294). Three-factor model of the BAPQ-SF was confirmed. Correlations of the BAPQ-SF with the Autism-Spectrum Quotient (AQ) and the Delta 10 suggest convergent and discriminant validity of the BAPQ-SF.

Autism Phenotype

Research has highlighted potential differences in the phenotypic and clinical presentation of autism spectrum conditions across sex. Furthermore, the measures utilised to evaluate autism spectrum conditions may be biased towards the male autism phenotype. It is important to determine whether these instruments measure the autism phenotype consistently in autistic men and women. This study evaluated the factor structure of the Autism Spectrum Quotient Short Form in a large sample of autistic adults. It also systematically explored specific sex differences at the item level, to determine whether the scale assesses the autism phenotype equivalently across males and females. Factor analyses were conducted among 265 males and 285 females. A two-factor structure consisting of a social behaviour and numbers and patterns factor was consistent across groups, indicating that the latent autism phenotype is similar among both autistic men and women. Subtle differences were observed on two social behaviour item thresholds of the Autism Spectrum Quotient Short Form, with women reporting scores more in line with the scores expected in autism on these items than men. However, these differences were not substantial. This study showed that the Autism Spectrum Quotient Short Form detects autistic traits equivalently in males and females and is not biased towards the male autism phenotype.

Autism Phenotype

The extant literature regarding psychometric properties of measures of subclinical adult autism traits is sparse. The current study investigated the validity and internal consistency reliability of the 26-item Autism Quotient (AQ-26), a self-report measure of autism traits, in a nonclinical young adult sample. Results indicated significantly better model fit with an 18-item measure (AQ-18), with optimal fit indices. Otherwise, AQ-18 and AQ-26 findings were similar and are discussed together. A three-factor model best fit the data. Scores demonstrated similar correlations in expected directions with the Empathy Quotient and Broad Autism Phenotype (BAP) Questionnaire. Expected differences were also observed when college major, gender, and BAP/non-BAP groups were compared. Despite somewhat weaker evidence for the 26/18-Details/Patterns factor, findings indicate that the AQ-26 and AQ-18 are promising measures of the three traits of subclinical autism spectrum symptomatology.

International Statistical Classification

The 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD-11) marks a paradigm shift in the diagnosis of personality disorders: In the near future, their classification will no longer be categorical, but dimensional along the severity of personality impairments and optionally regarding the presence of maladaptive personality traits. This study examines the reliability and validity of the German version of the Personality Inventory for ICD-11 (PiCD), a questionnaire designed to assess ICD-11 maladaptive personality domains, in a clinical and nonclinical sample (N = 939). The factor structure of the PiCD was examined using Exploratory Factor Analysis (EFA) and showed a tendency for a four-factor model (Negative Affectivity, Dissociality, Detachment, and a bipolar factor Disinhibition-Anankastia). The subscales of the PiCD demonstrated acceptable to excellent reliability coefficients with Cronbach's α (.79 - .89) and McDonald's w (.76 - .90). Convergent and discriminant validity were examined in conjunction with other questionnaires and were found to be satisfactory. The results suggest that the German version of the PiCD is a reliable and largely valid measurement instrument for assessing ICD-11 maladaptive personality traits. However, further research on factor structure, appropriate cut-off as well as norm values is needed.

Caregiving Burden

There is insufficient knowledge about the psychometric properties of the Friedrich short form of the Questionnaire on Resources and Stress (QRS-F) used to measure the caregiving burden of caregivers of individuals with autism spectrum disorder (ASD). The present study, therefore, aimed to confirm the validity of the QRS-F. The data selected using the systematic sampling method were analyzed to verify the factor structure of the QRS-F on parents of individuals with ASD. Exploratory and confirmatory factor analyses were employed to confirm the validity and the factor structure of the scale. The Pearson correlation coefficient was calculated to verify the relation with other measures. The original factor model was not appropriate to assess the caregiving burden on parents of individuals with ASD because the models did not show adequate fit indices. The evaluation of results based on a total score was explored, which demonstrated the expected association between depression severity and caregiving time. Overall, this study supports the use of the QRS-F for measuring the caregiving burden of parents of individuals with ASD by comparing the total score with other related variables.

Purpose The Autism-Spectrum Quotient (AQ) is a widely used tool to quantify autistic traits in the general population. This study aims to report the distribution, group differences and factor structure of autistic traits in Indian general population. The work also assesses the criterion validity of AQ across three patient group samples – autism spectrum disorder (ASD), obsessive-compulsive disorder and social anxiety disorder. Design/methodology/approach In this study, psychometric properties of the adapted AQ were assessed among 450 neurotypical university students matched for age. Confirmatory factor analysis was done to see if the adapted AQ fits the original factor structure. Test–retest, internal consistency reliability and criterion validity were found out. Group differences (gender and field of study) in AQ were also assessed. Findings Autistic traits were found to be continuously distributed in the population, and patterns of group differences were consistent with previous studies. The adapted AQ had five factors resembling the original factor structure with a good fit, and 38 items instead of the original 50 items. Acceptable reliability coefficients were demonstrated along with criterion validity across clinical groups. Originality/value This work is the first to present the pattern of distribution and factor structure of autistic traits among neurotypical adults from Eastern India, a culturally different population, as well as a reliable and valid tool to assess autistic traits in Bengali, a language with 300 million speakers. The findings add to the growing literature on AQ measurement and the concept of autism as a quantitative trait, examined outside of the western samples.

Autism Phenotype

ABSTRACTWe conducted a web-based study investigating whether the probability of deriving four types of pragmatic inferences depends on the degree to which one has traits associated with the autism spectrum, as measured by the autism spectrum quotient test (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001). In line with previous research, we show that, independently of their autism spectrum quotient, participants are likely to derive those pragmatic inferences that can be derived by reasoning solely about alternatives that the speaker could have used. However, if the derivation of the pragmatic inference draws upon more complex counterfactual reasoning about what the speaker could have said, the probability that it is derived decreases significantly with one’s autism quotient. We discuss the consequences for theories of pragmatics in autism and for linguistic theorizing in general.
