Adolescents with schizotypal traits: A cases series

In a cases series with five adolescents we tested a treatment for adolescents with schizotypal traits. The intervention was previously designed and tested with adults, namely Evolutionary Systems Therapy for Schizotypy (ESTS).

ESTS is an integrative form of psychotherapy that comprises an evolutionarily based conceptualization with compassion focused and metacognitvely oritented approaches. We recently published the findings of a randomized controlled trial where we showed promising results. 75% of patients remitted from diagnosis and drop-out rates was below 10%.

In this new cases series we suggest how ESTS may be a feasible treatment for adolescents with schizotypal traits. All the partecipants concluded the study and the rate of missing sessions was below 10%. Moreover, 4 out of 5 patients remitted from diagnosis at the end of the schedule 6-month treatment, 1 out of 5 after an extended 9-month intervention.

A post-hoc interview showed how the adolescents described the intervention as effective, substainable and consistent with their goals. By considering how limited informat we have about effective treatments for adolescents with personality pathology (almost nothing for those struggling with schizotypal traits), we are really excited by these findings. Despite the preliminary nature of the study, the proposed model is elegible for larger sample size studies.
