However, it can also bean important period for developing resilience, positive interpersonal and behavioral patterns,especially for people who have difficulty trusting others. Thus, the early introductionof positive resources and practices can have both immediate and prophylactic effects foryoung adults. This is randomized control study aimed to examine the efficacy of a theorydriven,multi-component, positive psychology group intervention to improve well-being ina clinical sample of 77 young adults with paranoid tendencies compared to a waiting-listgroup. Results showed that the intervention protocol was highly acceptable for participants,with high participant satisfaction, attendance, and adherence rates. At the end of the grouptherapy, mixed-effect models for repeated measures reflected that the participants had a significantimprovement in some of the primary well-being outcomes with medium and largeeffect sizes (ranging 0.57–0.89). These changes were maintained in the follow-up assessmentafter 3 and 6 months. The results of this randomized control trial provide furtherevidence that a positive psychology approach can help promote eudemonic well-being andself-esteem for young people seeking psychotherapy in a University Psychology Clinic.
