Although it is recognised that autism spectrum disorder (ASD) and personality disorders (PDs) have a variety of factors in common, the exact nature of the relationship between ASD and the PDs remains unclear. The overlapping symptom profiles and complexities in developmental trajectories in ASD and PDs can lead to diagnostic uncertainty and to…

We developed and validated a self-report scale for screening pathological traits of dependent personality disorder (DPD) from the Hierarchical Taxonomy of psychopathology (HiTOP) perspective. The sample was 693 adults who answered the new scale, the Dimensional Clinical Personality Inventory DPD (IDCP-DPD), the PID-5, the FFDI, and the FFBI. The…

For autism spectrum disorder (ASD) in adults there are several diagnostic instruments available with a need for consideration of the psychometric properties. This study aimed to conduct a first psychometric evaluation of a new diagnostic ASD instrument, the NIDA (Dutch Interview for Diagnostic assessment of ASD in adults) in 90 adult males without…

Background: People with intellectual disability often receive diagnoses which may complicate their clinical care. Among these, personality disorder diagnoses are still considered contentious. Little is also known on the perspectives of staff caring for people with intellectual disability who have received a personality disorder diagnosis. Methods:…

Diagnostic criteria for autism are relatively vague, and may lead to over and underdiagnosis when applied without clinical expertise. Indeed, autism is best reliably identified by experienced clinicians who take into account qualitative aspects of the condition. When assessing for autism in women, little guidance exists to support clinicians…

Multi-exceptional children often have deficits in auditory, visual, or sensory processing. As few psychologists have training in modalities, these deficits may be misdiagnosed as AD/HD, Nonverbal Learning Disorder, Autism, Dyslexia, or a host of personality disorders. This article describes the symptoms of these processing deficits and offers…

The similarities between high functioning autism (HFA) and schizotypal-schizoid personality disorder (SSPD) in terms of social cognition and interpersonal deficits may lead to confusion in symptom interpretation, and consequently result in misdiagnosis. Thus, this study aims to investigate differences in mentalizing with particular interest on the…

In "DSM-5" there has been a move to dimensional personality disorder (PD) diagnosis, incorporating personality theory in the form of the five-factor model (FFM). It proposes an alternative assessment system based on diagnostic indicators and the FFM, while retaining "DSM-IV" categorical criteria. Four individuals with…

Borderline personality disorder (BPD) is a prevalent psychiatric illness that often first presents at college. If left untreated, BPD can lead to severe disability or fatality. While multiple evidence-based treatments for BPD exist, most are resource intensive and, therefore, difficult to implement at the typical college mental health center.…

Recent changes to the diagnosis of child antisocial behavior provide different methods of conceptualizing it (e.g., traditional symptom-based diagnoses and alternative trait-based methods). However, there is little research on how psychology students might use these different methods and what kind of instructional formats might be amenable to…

Schizophrenia and schizotypy have been often associated with above average creativity; however, empirical studies on the relationship between schizophrenia spectrum disorders and enhanced creativity generated inconsistent results. This research investigates if the association between schizophrenia spectrum disorders and creative potential levels…

College students may be misdiagnosed as personality disordered when in fact their problems are better explained by their upbringing. Growing up with a personality disordered parent may cause them to initially present with what appear to be personality disordered traits due to issues such as not learning adequate coping skills. Accurate diagnosis…

Victimisation is a traumatic experience linked to development of Borderline personality disorder (BPD). However, there is limited research investigating the developmental journey prior to BPD diagnosis. School environments offer an opportunity for BPD prevention and early intervention. A survey with 19 Australian family carers of people with BPD…

Background and objectives: Personality disorders are enduring, persistent and pervasive disorders of inner experience and behavior that cause distress or significant impairment in social functioning. They have strong relationship to offending and violence; our aim in the study was to determine the prevalence rate of each specific types of…

Background: To describe the characteristics of those with autism spectrum disorder (ASD) treated within a forensic intellectual disability hospital and to compare them with those without ASD. Method: Service evaluation of a cohort of 138 patients treated over a 6-year period. Results: Of the 138, 42 had an ASD. Personality disorders and harmful…
