It is unknown whether sex influences the diagnostic evaluation of autism spectrum disorder, or whether male and female adults within the spectrum have different symptom profiles. This study reports sex differences in clinical outcomes for 1244 adults (935 males and 309 females) referred for autism spectrum disorder assessment. Significantly, more males (72%) than females (66%) were diagnosed with an autism spectrum disorder of any subtype (x2 = 4.09; p = 0.04). In high-functioning autism spectrum disorder adults (IQ > 70; N = 827), there were no significant sex differences in severity of socio-communicative domain symptoms. Males had significantly more repetitive behaviours/restricted interests than females (p = 0.001, d = 0.3). A multivariate analysis of variance indicated a significant interaction between autism spectrum disorder subtype (full-autism spectrum disorder/partial-autism spectrum disorder) and sex: in full-autism spectrum disorder, males had more severe socio-communicative symptoms than females; for partial-autism spectrum disorder, the reverse was true. There were no sex differences in prevalence of co-morbid psychopathologies. Sex influenced diagnostic evaluation in a clinical sample of adults with suspected autism spectrum disorder. The sexes may present with different manifestations of the autism spectrum disorder phenotype and differences vary by diagnostic subtype. Understanding and awareness of adult female repetitive behaviours/restricted interests warrant attention and sex-specific diagnostic assessment tools may need to be considered.

Accessible summary Mindfulness helps people focus instead of worrying about the past or future. We talked to six people who took part in a mindfulness group. They all had intellectual disabilities and were in hospital for mental health problems. They told us the group helped, and we hope that mindfulness can help other people too. Summary The study focused on the effectiveness of group mindfulness for people with intellectual disabilities in an assessment and treatment unit. Six participants with mild or moderate intellectual disabilities were interviewed using semi‐structured interviews. The interviews focused on identifying the benefits and difficulties of using mindfulness. The interviews were analysed using thematic analysis. Five themes were identified which were categorised into interpersonal (‘helping people’) and intrapersonal (‘focusing on one particular thing’; ‘improving skills’; get rid of all nasty bad stuff you want to get rid of’) benefits. The theme ‘bit too late to teach old dog new tricks’ captured the difficulties encountered. The themes highlighted that people with intellectual disabilities were able to form an understanding of mindfulness and were able to benefit from the intervention.

This audit explores readmissions into inpatient services for adults with intellectual disabilities, using two case studies. Thirteen semi-structured interviews were conducted with professionals, to gain a multidisciplinary perspective, between February and March 2010, and analysed using thematic analysis. The main themes found in case study 1 were: narrow focus, environment, communication, early discharge, and deterioration. The main themes found in case study 2 were: deterioration, communication, discharge too soon, and environment. The aims of the audit were to contribute to good practice and provide a better understanding of readmission within our services.
