  • Control group: TAU (waiting‐list control)


Details of conditions:
  • MBT‐I is not described in the clinical trials record; completion of the intervention is described as attending three cycles of group MBT‐I (each cycle of MBT‐I has 12 sessions).

  • TAU is not described in the clinical trials record.


Duration of intervention: 18 months
Duration of trial: 21 months
Length of follow‐up: 3 months post‐intervention
Outcomes Primary outcomes of trial
  • Completion of 3 MBT‐I group cycles [time frame = 18 months]

  • Participants to have attended ≥ 75% (9 or more out of 12) of scheduled sessions to consider this successful completion of the programme

  • ≥ 50% participants who commenced session one to have completed the intervention as described above to consider the group successful


Secondary outcomes of trial (time frame for all secondary outcomes is 21 months; measures administered one week pre‐, one week post‐ and three months post‐intervention)
  • Interpersonal functioning: change in interpersonal functioning using Inventory of Interpersonal Problems‐32, pre‐ and post‐intervention

  • Impulsivity: change in impulsivity using Barrett Impulsiveness Scale (BIS) pre‐ and post‐intervention

  • Mental state: change in difficulties with reflective functioning using Reflective Functioning Questionnaire (RFQ) pre‐ and post‐intervention

  • Mental state: change in depressive symptoms using Beck's Depression Inventory (BDI) pre‐ and post‐intervention

  • Mental state: change in anxiety symptoms using Beck's Anxiety Inventory (BAI) pre‐ and post‐intervention

  • Social functioning: change in social functioning and satisfaction using Social Adjustment Scale‐Self Report (SAS‐SR) pre‐ and post‐intervention

  • Global functioning: quantitative data measuring change in overall symptoms and functioning using Clinical Outcomes in Routine Evaluation‐Outcome Measure (CORE‐OM) pre‐ and post‐intervention

  • Challenging behaviour: quantitative data from behavioural proxy measures examining change in the number of challenging behaviours pre‐ and post‐intervention [time frame = 21 months]; number of discipline procedures (reports) and Incentives and Enhanced Privileges (IEPs) will be examined over a 3‐month period pre‐intervention, 3‐month period during the intervention and 3‐month period post‐intervention to allow a behavioural proxy measure of negative (reports) vs positive (IEPs) behaviours

  • Satisfaction with treatment: qualitative data from follow‐up interviews examining understanding of and overall satisfaction of intervention; semi‐structured interview schedule to be completed 1 week post‐ and 3 months post‐intervention; examines participants' understanding of the concepts of the intervention, in addition to their overall satisfaction
