- PurposeAutism Spectrum Disorder (ASD) occurs in 1-1.5% of the general population and possibly in up to 20% of psychiatric outpatients. Post Traumatic Stress Disorder (PTSD) occurs at some point in life in 4% of the general population and in 14-20% of psychiatric outpatients. Knowledge about how PTSD manifests in people with ASD is important in order for it to be correctly diagnosed and intervened for.MethodsThis study investigated the relationship between PTSD and autism among adult psychiatric outpatients (N = 90) of whom 63 had ASD or subthreshold ASD based on DSM-5 criteria. The study group was subjected to in-depth psychiatric assessments using validated instruments. Diagnosis of PTSD was made based on the Mini International Neuropsychiatric Interview (MINI).ResultsThere was a trend towards PTSD being more common among participants with ASD compared to participants without ASD, although significant differences could not be shown in this small sample. 21% of the ASD group had current PTSD, compared to 4% of the study group without ASD. There were no differences between the groups regarding exposure to trauma. There was a trend towards a relationship between number of autism symptoms and hyperarousal symptoms in PTSD. Conversely, the PTSD symptom of irritability/outbursts of anger, was significantly associated with number of autism symptoms.ConclusionsA subgroup of psychiatric outpatients with ASD also suffer from PTSD. Hyperarousal symptoms are possibly more prevalent in the presentation of PTSD in individuals/patients with ASD compared to those without ASD.

- With increasing numbers of children being diagnosed with neurodevelopmental disorders (NDDs) attention has been drawn to these children's physical health. We aimed to identify the prevalence of defined physical problems (epilepsy, migraine, asthma, cancer, diabetes, psoriasis, lactose intolerance, celiac disease, diarrhea, constipation, daytime enuresis, encopresis) in a nationwide population of 9- and 12-year-old twins subdivided into those with and without indications of NDDs. Parents of 28,058 twins participated in a well-validated telephone interview regarding their children's mental health and answered questions about their physical problems. The results indicate a high rate of physical problems in children with NDDs, particularly in those with indications of the presence of combinations of several NDDs.

- What do we know about the prevalence and the specific features of autism spectrum disorders (ASDs) among subjects in forensic psychiatry and special youth centres? A clinical case series consisting of 42 subjects with ASD, recruited from three well-characterized populations in forensic psychiatry and special youth care, was used to determine: 1) the prevalence of ASD in these institutions (at least 13%), 2) the distribution of diagnostic criteria in this special population (mostly social interaction and communication problems, few or atypical flexibility problems), 3) the degree of comorbidity (the rule rather than the exception), 4) neuropsychological test profiles (lowered IQ with uneven profiles), 5) types of crimes and offences (very heterogeneous, often stress-related with dissociated features), 6) mental health care needs (high), and 7) special clinical features (especially expressions of flexibility deficits in non-classical areas and proneness to dissociation). This descriptive study indicates that ASD is a clinically relevant problem among forensic populations that has to be considered in diagnostics, assessments of needs and treatment planning.

Tidskriftsartikel (refereegranskat)abstract
- The Autism – Tics, AD/HD, and other Comorbidities inventory (A-TAC) is a comprehensive interview for evaluating problems related to autism spectrum disorders (ASD), tic disorders, attention-deficit/hyperactivity disorder (AD/HD), and common comorbid conditions in children and adolescents. A-TAC telephone interviews were administered to parents of 2,957 children aged nine- or twelve-years, representing one in each twin pair included in the population- based Child and Adolescent Twin Study in Sweden (CATSS). A total of 16.4% were screen-positive for one or several of the targeted disorder, 1.3% for ASD and 5.6% for AD/HD. All types of problems were more common among boys, with the exception of those related to “eating habits”. They were all dimensionally/continuously distributed, highly inter-correlated, and overlapped across types. They aggregated in three ba- sic factors corresponding to externalizing/disruptiveness, socio-communicative problems, and compulsiveness. Population-based data on problems in children thus challenge current categorical diagnostic definitions, calling for dimen- sional and complementary models of problem descriptions.

- OBJECTIVE: To assess prevalence figures for psychiatric disorders among institutionalized adolescents due to behavioural problems and/or delinquency. METHOD: Participants were recruited from consecutive referrals to/or treated at two Swedish adolescent units, SIS1 (n = 60) and SIS2 (n = 70) with ranging age of 12-20.3 years (mean age = 16.2; SD = 1.8) during 1 year. Clinical and diagnostic information was used to generate DSM-IV diagnoses. RESULTS: One or several neuropsychiatric disorders were diagnosed in 53% of all subjects: 39% met DSM-IV diagnostic criteria for attention deficit/hyperactivity disorder (AD/HD), 15% for a pervasive developmental disorder (referred to as autism spectrum disorders, ASDs) and 8% had a mental retardation (referred to as a learning disability, LD). The collapsed prevalence for psychiatric disorders requiring specialist attention was 66%, counting severe depression and psychotic disorders but not substance use. About one in three of all adolescents in the study were given psychopharmacological treatment. CONCLUSION: Published studies and this clinical survey clearly indicate that systematic studies of mental health needs among institutionalized adolescents are warranted to form the basis of adequate treatment and support measures.

- The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing longitudinal twin study targeting all twins born in Sweden since July 1, 1992. Since 2004, parents of twins are interviewed regarding the children's somatic and mental health and social environment in connection with their 9th or 12th birthdays (CATSS-9/12). By January 2010, 8,610 parental interviews concerning 17,220 twins had been completed, with an overall response rate of 80%. At age 15 (CATSS-15) and 18 (CATSS-18), twins and parents complete questionnaires that, in addition to assessments of somatic and mental health, include measures of personality development and psychosocial adaptation. Twin pairs in CATSS-9/12 with one or both twins screening positive for autism spectrum disorders, attention deficit/hyperactivity disorder, tic disorders, developmental coordination disorder, learning disorders, oppositional defiant disorder, conduct disorder, obsessive-compulsive disorder, and/or eating problems have been followed with in-depth questionnaires on family, social environment and personality, and subsequently by clinical assessments at age 15 together with randomly selected population controls, including 195 clinically assessed twin pairs from the first 2 year cohorts (CATSS-15/DOGSS). This article describes the cohorts and study groups, data collection, and measures used. Prevalences, distributions, heritability estimates, ages at onset, and sex differences of mental health problems in the CATSS-9/12, that were analyzed and found to be overall comparable to those of other clinical and epidemiological studies. The CATSS study has the potential of answering important questions on the etiology of childhood mental health problems and their role in the development of later adjustment problems.

- OBJECTIVE: The authors describe personality development and disorders in relation to symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders. METHOD: Consecutive adults referred for neuropsychiatric investigation (N=240) were assessed for current and lifetime ADHD and autism spectrum disorders and completed the Temperament and Character Inventory. In a subgroup of subjects (N=174), presence of axis II personality disorders was also assessed with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). RESULTS: Patients with ADHD reported high novelty seeking and high harm avoidance. Patients with autism spectrum disorders reported low novelty seeking, low reward dependence, and high harm avoidance. Character scores (self-directedness and cooperativeness) were extremely low among subjects with neuropsychiatric disorders, indicating a high overall prevalence of personality disorders, which was confirmed with the SCID-II. Cluster B personality disorders were more common in subjects with ADHD, while cluster A and C disorders were more common in those with autism spectrum disorders. The overlap between DSM-IV personality disorder categories was high, and they seem less clinically useful in this context. CONCLUSIONS: ADHD and autism spectrum disorders are associated with specific temperament configurations and an increased risk of personality disorders and deficits in character maturation.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: A subgroup of persons with anorexia nervosa (AN) have been proposed to have sociocommunicative problems corresponding to autism spectrum disorders [ASDs, i.e. DSM-IV pervasive developmental disorders (PDDs): autistic disorder, Asperger's disorder, PDD not otherwise specified (NOS)]. Here, clinical problems, personality traits, cognitive test results and outcome are compared across 16 subjects (32%) with teenage-onset AN who meet or have met ASD criteria (AN+ASD), 34 ASD-negative AN subjects and matched controls from a longitudinal Swedish study including four waves of independent assessments from the teens to the early thirties.MethodThe fourth wave included the Structured Clinical Interview for DSM-IV (SCID)-I and the SCID-II (cluster C, i.e. 'anxious' PDs) interviews, the Asperger Syndrome Diagnostic Interview, self-assessments by the Autism Spectrum Quotient and the Temperament and Character Inventory, neurocognitive tests by subscales from the Wechsler scales, continuous performance tests, Tower of London, and Happé's cartoons. RESULTS: The ASD assessments had substantial inter-rater reliability over time (Cohen's κ between 0.70 and 0.80 with previous assessments), even if only six subjects had been assigned a diagnosis of an ASD in all four waves of the study, including retrospective assessments of pre-AN neurodevelopmental problems. The AN+ASD group had the highest prevalence of personality disorders and the lowest Morgan-Russell scores. The non-ASD AN group also differed significantly from controls on personality traits related to poor interpersonal functioning and on neurocognitive tests. CONCLUSIONS: A subgroup of subjects with AN meet criteria for ASDs. They may represent the extreme of neurocognitive and personality problems to be found more generally in AN.

- Community-based studies have consistently shown a sex ratio heavily skewed towards males in autism spectrum disorders (ASD). The factors underlying this predominance of males are largely unknown, but the way girls score on standardized categorical diagnostic tools might account for the underrecognition of ASD in girls. Despite the existence of different norms for boys and girls with ASD on several major screening tests, the algorithm of the Autism Diagnosis Interview-Revised (ADI-R) has not been reformulated. The aim of our study was to investigate which ADI-R items discriminate between males and females, and to evaluate their weighting in the final diagnosis of autism. We then conducted discriminant analysis (DA) on a sample of 594 probands including 129 females with ASD, recruited by the Paris Autism Research International Sibpair (PARIS) Study. A replication analysis was run on an independent sample of 1716 probands including 338 females with ASD, recruited through the Autism Genetics Resource Exchange (AGRE) program. Entering the raw scores for all ADI-R items as independent variables, the DA correctly classified 78.9% of males and 72.9% of females (P<0.001) in the PARIS cohort, and 72.2% of males and 68.3% of females (P<0.0001) in the AGRE cohort. Among the items extracted by the stepwise DA, four belonged to the ADI-R algorithm used for the final diagnosis of ASD. In conclusion, several items of the ADI-R that are taken into account in the diagnosis of autism significantly differentiates between males and females. The potential gender bias thus induced may participate in the underestimation of the prevalence of ASD in females.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Brief Obsessive Compulsive Scale (BOCS), derived from the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the children's version (CY-BOCS), is a short self-report tool used to aid in the assessment of obsessive-compulsive symptoms and diagnosis of obsessive-compulsive disorder (OCD). It is widely used throughout child, adolescent and adult psychiatry settings in Sweden but has not been validated up to date.Aim: The aim of the current study was to examine the psychometric properties of the BOCS amongst a psychiatric outpatient population.Method: The BOCS consists of a 15-item Symptom Checklist including three items (hoarding, dysmorphophobia and self-harm) related to the DSM-5 category "Obsessive-compulsive related disorders", accompanied by a single six-item Severity Scale for obsessions and compulsions combined. It encompasses the revisions made in the Y-BOCS-II severity scale by including obsessive-compulsive free intervals, extent of avoidance and excluding the resistance item. 402 adult psychiatric outpatients with OCD, attention-deficit/hyperactivity disorder, autism spectrum disorder and other psychiatric disorders completed the BOCS.Results: Principal component factor analysis produced five subscales titled "Symmetry", "Forbidden thoughts", "Contamination", "Magical thoughts" and "Dysmorphic thoughts". The OCD group scored higher than the other diagnostic groups in all subscales (P < 0.001). Sensitivities, specificities and internal consistency for both the Symptom Checklist and the Severity Scale emerged high (Symptom Checklist: sensitivity = 85%, specificities = 62-70% Cronbach's alpha = 0.81; Severity Scale: sensitivity = 72%, specificities = 75-84%, Cronbach's alpha = 0.94).Conclusions: The BOCS has the ability to discriminate OCD from other non-OCD related psychiatric disorders. The current study provides strong support for the utility of the BOCS in the assessment of obsessive-compulsive symptoms in clinical psychiatry.
