There is a need for brief screening instruments for autistic spectrum disorders (ASD) that can be used by frontline healthcare professionals to aid in the decision as to whether an individual should be referred for a full diagnostic assessment. In this study we evaluated the ability of a short form of the autism spectrum quotient (AQ) questionnaire, the 10(More)
OBJECTIVES The aim of the study was to explore the relationship between exercise identity and exercise dependence. We hypothesized that stronger exercise identities would be associated with greater odds of experiencing exercise dependence symptoms. DESIGN Logistic regression was used to assess the extent of association between exercise identity and the(More)
The primary aim of this article was to provide a structural validation of the 28-item Autism Spectrum Quotient-Short Form questionnaire in a sample of adults with clinically diagnosed autism spectrum disorders (n = 148). Confirmatory factor analysis demonstrated that the proposed structure, comprising a second-order Social Skills factor subsuming(More)
This article reports on gender ratio, age of diagnosis and the duration of assessment procedures in autism spectrum disorder diagnosis in a national study which included all types of clinical services for children and adults. Findings are reported from a retrospective case note analysis undertaken with a representative sample of 150 Scottish children and(More)
Recent studies have suggested that the structure of psychopathology may be usefully represented in terms of a general factor of psychopathology (p-factor) capturing variance common to a broad range of symptoms transcending diagnostic domains in addition to specific factors capturing variance common to smaller subsets of more closely related symptoms. Little(More)
It is common to administer measures of autistic traits to those without autism spectrum disorders (ASDs) with, for example, the aim of understanding autistic personality characteristics in non-autistic individuals. Little research has examined the extent to which measures of autistic traits actually measure the same traits in the same way across those with(More)
It has previously been noted that inventories measuring traits that originated in a psychopathological paradigm can often reliably measure only a very narrow range of trait levels that are near and above clinical cutoffs. Much recent work has, however, suggested that autism spectrum disorder traits are on a continuum of severity that extends well into the(More)
The study outlines the evaluation of an intellectual disability screening tool, the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q), with two age groups. A number of aspects of the reliability and validity of the CAIDS-Q were assessed for these two groups, including inter-rater reliability, convergent and discriminative(More)
BACKGROUND The present study aimed to investigate whether there is an association between type of living environment (urban versus rural) and anxiety, depression and psychosis in the Scottish population. METHODS Data were obtained from the Scottish Neighbourhood Statistics database on Scottish Index of Multiple Deprivation and urban-rural classifications(More)
The present review argues that the reification of abstract concepts provides a psychological mediating mechanism for calendar and lightning calculation and possibly even all savant skills. The argument, which draws heavily on the synaesthesia literature has two main strands. First, there is anecdotal evidence for the presence and utilisation of highly(More)
