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.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291711002881_sec_a002\"><jats:title>Method<\/jats:title><jats:p>The fourth wave included the Structured Clinical Interview for DSM-IV (SCID)-I and the SCID-II (cluster C, i.e. \u2018anxious\u2019 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 Happ\u00e9's cartoons.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291711002881_sec_a003\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>The ASD assessments had substantial inter-rater reliability over time (Cohen's \u03ba 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\u2013Russell scores. The non-ASD AN group also differed significantly from controls on personality traits related to poor interpersonal functioning and on neurocognitive tests.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291711002881_sec_a004\" sec-type=\"conclusion\"><jats:title>Conclusions<\/jats:title><jats:p>A subgroup of subjects with AN meet criteria for ASDs.
