The impact of a combined mentalisation-based therapy and therapeutic community programme for adolescents with borderline personality disorder traits on service utilisation in Western Australia.

This study assessed the effect of a mentalisation-based therapy (MBT) treatment programme on the utilisation of Western Australian public hospitals for mental health presentations over an 18-month period. Hospital data included the number of visits to the emergency department (ED), the number of inpatient admissions to hospital and length of stay of the admissions. Participants included 76 adolescents aged 13-17 years old, who presented with borderline personality disorder (BPD) traits. The Touchstone treatment programme is a time-limited intensive programme that utilises MBT in the context of a therapeutic community. Hospital data for the participants were collected and analysed from three time points; 6 months prior to attending the programme, during the 6-month programme (active treatment) and 6 months after the programme. Results found a statistically significant decrease in hospital utilisation from pre to post programme, with a decline in ED visits, inpatient admissions and admission length of stay. This study presents promising preliminary evidence for the effectiveness of an intensive MBT programme as an intervention for adolescents with BPD features and has significant implications for the public health system in terms of providing effective community-based treatment for this difficult to treat population as well as reducing pressure on tertiary care.

The Utility of Natural Language Samples for Assessing Communication and Language in Infants Referred with Early Signs of Autism.

Natural Language Sampling (NLS) offers clear potential for communication and language assessment, where other data might be difficult to interpret. We leveraged existing primary data for 18-month-olds showing early signs of autism, to examine the reliability and concurrent construct validity of NLS-derived measures coded from video-of child language, parent linguistic input, and dyadic balance of communicative interaction-against standardised assessment scores. Using Systematic Analysis of Language Transcripts (SALT) software and coding conventions, masked coders achieved good-to-excellent inter-rater agreement across all measures. Associations across concurrent measures of analogous constructs suggested strong validity of NLS applied to 6-min video clips. NLS offers benefits of feasibility and adaptability for validly quantifying emerging skills, and potential for standardisation for clinical use and rigorous research design.
