Background and study aims
This research is an experiment to see if a special kind of therapy (called MIT-G) is better than the usual treatment for teenagers who have some problems with their personalities. We want to find out if this new therapy helps them feel better and have better relationships with others.
We will look at a few main things: how severe their problems are, how well they get along with people, if they feel sad, if they like the therapy, and if their parents or caregivers feel less stressed and more confident in helping them. We'll also check if some things that might change during the therapy actually do change, like how they think about things, how well they understand their own emotions, and how impulsive they are.
Based on some earlier small studies, we think that the new therapy might work better than the usual therapy. We think that the teenagers who get the new therapy will get better with their problems and how they interact with others. We also think that the new therapy might help them understand their feelings better and be less impulsive.
We also guess that the teenagers who get the new therapy will like it and feel good about it. We hope this study will help us learn if the new therapy is a good choice for teenagers who need help with their personalities.
Who can participate?
Kids between the ages of 14 and 18 who are getting regular treatment might be included in this study. The researchers are looking at whether these kids have something called a "personality disorder" which is diagnosed by special doctors trained to understand mental health. They use a special interview called the "Structured Clinical Interview for DSM–IV Personality Disorders" to figure this out.
What does the study involve?
The kids who want to be part of the study will be chosen by chance, like flipping a coin. Some will get a special therapy called "MIT-G," and others will have to wait and get the normal help that's usually given. We will look at how they're doing before they start, then after about 4 months, and again after 6 months.
The doctors and scientists will make sure everything is fair and safe. If the kids who have to wait for normal help still need the special therapy later, they will get it too, even if we can't check on them after 6 months.

| Scientific title | Metacognitive Interpersonal Group Therapy for Adolescents (MIT-GA) with personality disorders: a randomized controlled trial |
| Study objectives | 1. We predict that MIT-GA would lead to greater improvements in symptoms and interpersonal functioning than the control group 2. We predict that the putative mechanisms of change, ie, global metacognition, alexithymia – ie, awareness of one's own emotions – and impulsivity would improve more in the MIT-GA arm 3. Our hypothesis is that patients receiving MIT-GA will accept the treatment and subjectively experience it as positive and satisfactory. |
| Ethics approval(s) |
Approved 01/10/2018, Clinical Research Ethics Committee of La Rioja (CIBIR. C/ Piqueras, 98, Logroño, 26006, Spain; +34 941 278 855; cibir@riojasalud.es), ref: PI482 |
| Health condition(s) or problem(s) studied | Personality disorders |
| Intervention | Participants will be randomly assigned (1:1) with permuted block sizes of three or five, to receive MIT–GA or waiting list plus treatment as usual (TAU). Assessments of symptoms, functioning and psychological processes will be conducted at 0 months (baseline), 4 months (post-treatment), and 6-month follow-up. Upon request of the ethics committee, participants in the waiting list plus TAU arm will have to begin MIT–GA once both groups have been completed end-of-treatment assessment, without waiting for the follow-up, so TAU group will can not be evaluated at 6-month follow-up. Metacognitive Interpersonal Therapy (MIT) has first manualized principle for individual therapy (Dimaggio et al., 2015, 2020) and then a protocol for a time-limited group treatment has been devised and empirically tested (Inchausti et al., 2020; Popolo et al., 2018, 2019, 2022). And on this basis, we built an adaptation of the group protocol for adolescents (MIT–GA) which we are testing here. The MIT–GA program therefore includes: (1) At least two individual sessions addressed to establish an optimal therapeutic alliance with group facilitators, to evaluate and enhance motivation to change, to collect assessment material for drafting a formulation shared with the patient, of dominant maladaptive interpersonal schemas, and to improve affect–modulating strategies, especially in adolescents with severe emotional and behavioural dysregulation; (2) Two psychoeducational group–sessions introducing the principles of the treatment; (3) 16 weekly group–sessions for adolescents; and (4) a further 5 MIT-G sessions for adolescent’ parents or caregivers, scheduled concurrently to the adolescent group–sessions. The aims of the additional parents/caregivers’ sessions are: (i) to help them understand common contemporary problems for adolescents and to acquire some useful emotional and behavioural tools to help adolescents feeling understood and validated, to support them in planning daily activities, in firmly setting boundaries when need, and using effective parenting strategies such as boost adolescent’s self-esteem; (ii) to help caregivers improve awareness of their own mental states, i.e. thoughts, feelings, desires, intentions when relating with their children so to realize how their behaviour is not just guided by norms, but by their own personal subjectivity; (iii) to identify and understand their own maladaptive schemas and possible negative influence on the relationship with their young person. Thanks to this improved awareness of their own psychological functioning, they can start to communicate and behave with their children in healthier and more adaptive ways; and (iv) to recognize and promote the importance of parental self-care as a way to improve their emotional state and, in this way, improve their ability to reflect on themselves and their children. It is important to emphasize that, throughout the 5 parental sessions, significant emphasis is placed on healthy individual aspects in themselves, hence the focus on developing awareness of maladaptive schema alongside awareness of positive representations of oneself and the others, and the ubiquity of positive and understandable social drives within individuals. Consistently with MIT–G structure (Popolo et al., 2019), the 16 group sessions each last approximately 120 minutes; individual sessions last 45–60 min, with one session, or more, before beginning the group, one session at the midpoint, and a last session after completion of the program. In general, the middle session enabled discussion of problematic issues in the group and if required, repair of alliance ruptures. The last session addressed how the patient experienced the group, summarized problems identified, and strategies learned, considered the groups utility in informing everyday functioning, and identified remaining treatment goals. It also included a reformulation letter to sustain and promote further changes (Dimaggio et al., 2015). Group sessions will be divided into blocks of 2 or 3 sessions for each specific evolutionarily selected motive. MIT utilizes the creation of a shared formulation that makes patients sustained in the pursuit of these evolutionarily selected wishes, such as social rank, attachment, exploration, group inclusion and so forth (Dimaggio et al., 2015, 2020). During the first session of each block, each motivational system is described in simple language. Then, a series of video clips are presented, taken from movies or cartoons, demonstrating situations where actors’ behaviour was driven by the specific motive. Systems were presented in the following order: (1) social rank/competition, (2) group inclusion/affiliation, (3) attachment, (4) caregiving, (5) exploration, (6) sexuality, and (7) cooperation. After psychoeducation, therapists asked participants to write down a specific autobiographical memory where their actions were driven by that system. Therapists then selected one situation to be role–played. Across the program, all participants had to role–play at least one episode from their own life. The scene enacted was then replayed with the participant taking the part of the other. In the ensuing group discussion, the protagonist and other group members were asked to reason about what kind of mental states the participants might have experienced, further identifying verbal and nonverbal cues underpinning this position. In the second session concerning the same motive, participants were asked to attempt a problem–solving strategy during the roleplay, based on the mental states that they were experiencing at the time and the mental states they ascribed to others. Therefore, the second session (and the third in the case of cooperative system), focused on using psychological information in order to reach own goals, solve conflicts, and find and promote more fulfilling and cooperative relationships, termed metacognitive mastery (Semerari et al., 2003). TAU will consist of weekly individual consultations with participants’ usual clinical psychologists. TAU will be oriented to support participant’s emotional suffering from a cognitive-behavioural approach. No interventions aimed at promoting metacognition or providing psychoeducation on motivational systems underlying social behaviour will be included in TAU. Psychiatric consultation will be available in both TAU and MIT–GA groups if clinicians will consider it necessary or if request by the participant. The physical health of all participants will be monitored throughout the study. Considering a context of routine practice in a public service, the minimal treatment received (adherence) for subsequent assessments will be defined as attending 8 or more sessions of MIT–GA or TAU. In the MIT–GA arm, parents or caregivers’ group intervention will be delivered by the same group therapist. Attending at least 3 parent group sessions will be mandatory for subsequent analysis. |
