Mentalization Based Treatment - Introductory (MBT-I) Group for Male Prisoners With Borderline and/or Antisocial Personality Disorder

Not Applicable

• Conditions: Antisocial Personality Disorder (ASPD); Borderline Personality Disorder (BPD)
• Interventions: Other: Treatment as usual; Other: Mentalization Based Treatment-Introductory

• Registration Number: NCT04033835
• Lead Sponsor: NHS Greater Glasgow and Clyde

Brief Summary

Established evidence base with MBT for treatment of Borderline Personality Disorder (BPD) and/or Antisocial Personality Disorder (ASPD). Demographic information of United Kingdom prison population highlights large proportion of offenders with PD. There is no agreed universal approach to treatment of PD within Scottish prisons with large variance across the prison estate. MBT pilots in HMP Edinburgh and HMP Cornton Vale have demonstrated positive findings in female offenders which could be replicated in male populations.

Arm && Interventions

Group	Intervention	Description
Waiting list control	Treatment as usual	Treatment as usual
MBT-I	Mentalization Based Treatment-Introductory	12 sessions of MBT

Primary Outcome Measures

Name	Time	Method
Completion of three MBT-I group cycles	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 Outcome Measures

Name	Time	Method
Quantitative data measuring change in difficulties with interpersonal relationships pre- and post-intervention	21 months	Inventory of Interpersonal Problems-32 (IIP-32) to be administered one week pre-, one week post- and three months post-intervention. The scale measures difficulties with interpersonal relationships which are a core feature of personality disorder psychopathology.; There are 32 items scored on a 5 point scale (0-4) measuring 2 domains of affiliating and distancing (16 items each) difficulties with interpersonal relationships. There are 8 differing interpersonal relationship styles (4 each for affiliating and distancing). The maximum score therefore for each style is 16 (4 x 4 point scores), for each domain is 64 (16 x 4 point scores), and total score is 128 (32 x 4 point scores). The minimum score is 0. Higher values indicate increasing severity.
Quantitative data measuring change in anxiety symptoms pre- and post-intervention	21 months	Beck's Anxiety Inventory (BAI) to be administered one week pre-, one week post- and three months post-intervention. The scale measures anxiety symptoms which are a common feature of personality disorder psychopathology.; There are 21 items scored on a 4 point (0-3) scale measuring anxiety symptoms. The maximum score is 63 (21 x 3 point scores). The minimum score is 0. Higher values indicate increasing severity (0-21 - low anxiety; 22-35 - moderate anxiety; \>35 - potentially concerning levels of anxiety).
Quantitative data measuring change in social functioning and satisfaction pre- and post-intervention	21 months	Social Adjustment Scale - Self Report (SAS-SR) to be administered one week pre-, one week post- and three months post-intervention. The scale measures difficulties with social functioning and satisfaction which are common sequelae of personality disorder.; There are 54 items scored measuring instrumental and expressive performance over the past two weeks. They examine across 6 domains - work, social and leisure, extended family, primary relationship, parental, family unit. Within these domains, the items cover 4 categories - performance, friction with people, finer aspects of interpersonal relations, and feelings and satisfactions.
Qualitative data from follow up interviews of participants examining understanding of and overall satisfaction of intervention	21 months	Semi-structured interview schedule to be completed one week post- and three months post- intervention. This will examine participant's understanding of the concepts of the intervention, in addition to their overall satisfaction.
Quantitative data measuring change in difficulties with impulsivity pre- and post-control	21 months	Barrett Impulsiveness Scale (BIS) to be administered one week pre-, one week post- and three months post-intervention. The scale measures difficulties with impulsivity which is a core feature of personality disorder psychopathology.; There are 30 items scored on a 4 point (1-4) scale measuring impulsivity. The maximum score is 120 (30 x 4 point scores). The minimum score is 30 (30 x 1 point scores). Higher values indicate increasing severity.
Quantitative data measuring change in depressive symptoms pre- and post-intervention	21 months	Beck's Depression Inventory (BDI) to be administered one week pre-, one week post- and three months post-intervention. The scale measures depressive symptoms which are a common feature of personality disorder psychopathology.; There are 21 items scored on a 4 point (0-3) scale measuring depressive symptoms. The maximum score is 63 (21 x 3 point scores). The minimum score is 0. Higher values indicate increasing severity (1-10 - these ups and downs are considered normal; 11-16 - mild mood disturbance; 17-20 - borderline clinical depression; 21-30 - moderate depression; 31-40 - severe depression; \>40 - extreme depression).
Quantitative data measuring change in anxiety symptoms pre- and post-control	21 months	Beck's Anxiety Inventory (BAI) to be administered one week pre-, one week post- and three months post-intervention. The scale measures anxiety symptoms which are a common feature of personality disorder psychopathology.; There are 21 items scored on a 4 point (0-3) scale measuring anxiety symptoms. The maximum score is 63 (21 x 3 point scores). The minimum score is 0. Higher values indicate increasing severity (0-21 - low anxiety; 22-35 - moderate anxiety; \>35 - potentially concerning levels of anxiety).
Quantitative data measuring change in difficulties with reflective functioning pre- and post-intervention	21 months	Reflective Functioning Questionnaire (RFQ) to be administered one week pre-, one week post- and three months post-intervention. The scale measures difficulties with reflective functioning which is a core feature of personality disorder psychopathology.; There are 54 items scored on a 7 point (1-7) scale measuring 2 domains of certainty and uncertainty (26 items each) difficulties with reflective functioning. Two items do not score. Only extreme rankings score points for each item (i.e 7 or 1 scores 3, 6 or 2 scores 2 and 5 or 3 scores 1 depending on the item type). The maximum score therefore for each domain is 78 (26 x 3 point scores), and total score is 156 (52 x 3 point scores). The minimum score is 0. Higher values indicate increasing severity.
