NCT06415812

Brief Summary

Evolutionary Systems Therapy is a new form of therapy that has been previously tested in a randomized controlled trial and in a few cases of patients diagnosed with Cluster A personality disorders. The objective of the present study is to investigate the feasibility and preliminary efficacy of Evolutionary Systems Therapy in all forms of personality disorders. The study includes three project actions: (i) a case series on adolescents with personality disorders; (ii) a case series on young adults with personality disorders; (iii) an ecological momentary assessment study to confirm the conceptualization model on all the patients.

Outcome Measures

Primary Outcomes (3)

  • Rate of individual change in personality pathology over time

    At least 75% rate of change in personality pathology over time as defined by a downward trend in mean of total score of Personality Inventory for DSM-5 Brief Form)

    9 measurements: one month before the start of therapy, at the start of therapy, at the end of each of the 6 months of therapy, one month after the end of therapy.

  • Group change in personality pathology over time

    Group change in personality pathology over time as defined by statistically significant change of sample mean of total score of Personality Inventory for DSM-5 Brief Form)

    9 measurements: one month before the start of therapy, at the start of therapy, at the end of each of the 6 months of therapy, one month after the end of therapy.

  • Feasibility of the intervention

    At least 70% rate of completion, adherence, therapeutic alliance and adverse events

    6 measurements: at the end of each of the six months of therapy

Secondary Outcomes (3)

  • Differential effect of the intervention between interpersonal patterns

    9 measurements: one month before the start of therapy, at the start of therapy, at the end of each of the 6 months of therapy, one month after the end of therapy.

  • Specific effect of the intervention between interpersonal patterns

    40 measurements: 20 measurements in the month before surgery (2 measurements per day for the 10 days before the start of therapy) and 20 measurements in the month after surgery (2 measurements per day for the 10 days after the end of therapy)

  • Remission from diagnosis

    2 measurements: one at baseline assessment (once the intervention starts); one at final assessment (6 months after, that is after weekly scheduled 24 sessions)

Study Arms (1)

Psychotherapy

EXPERIMENTAL

All the participants receive as active treatment a form of psychotherapy for personality disorders (Evolutionary Systems Therapy). The treatment last 6 months (24 weekly sessions, each lasting 50-60 minutes).

Behavioral: Evolutionary Systems Therapy

Interventions

Evolutionary Systems Therapy is an individual form of psychotherapy (talk therapy) that has been previously tested trough a randomized controlled trial and a few cases series, confirming its feasibility and safety.

Masking Details
All data will be collected in a blinded manner by an assessor other than the therapists. Subsequently, the data will be anonymized and analyzed by a researcher from an institution different from the one in which the study takes place.
Purpose
TREATMENT
Intervention Model
SINGLE GROUP
Model Details: Two individual parallel groups will be recruited: adolescent patients and young adult patients. Both groups will receive a 6-month Evolutionary Systems Therapy treatment. Both groups will access a longitudinal evaluation of the effectiveness of the treatment. All the participants will access a more extensive ecological momentary assessment to evaluate the progress of specific psychopathological mechanisms that are the targets of the treatment. Consistent with the conceptualization model of Evolutionary Systems Therapy and with the scientific literature on dimensional and hierarchical models of psychopathology, this conceptualization will be shared with the patient based on three macro-functionings: externalizing patterns, internalizing patterns, schizotypal patterns.
