Abstract

Abstract: Background: An increasing need exists for suitable measures to evaluate treatment outcome in adolescents. YP-CORE is a pan-theoretical brief questionnaire developed for this purpose, but it lacks studies in different cultures or languages. Aims: To explore the acceptability, factor structure, reliability, validity, and sensitivity to change of the Finnish translation of YP-CORE. Methods: The study was conducted at the Department of Adolescent Psychiatry, Helsinki University Central Hospital. A Finnish translation was prepared by a team of professionals and adolescents. A clinical sample of 104 patients was asked to complete the form together with BDI-21 and BAI, and 92 of them filled the forms again after a 3-month treatment. Analysis included acceptability, confirmatory factor analysis, internal and test–re-test reliability, concurrent validity, influence of gender and age, and criteria for reliable change. Results: YP-CORE was well accepted, and the rate of missing values was low. Internal consistency ( α = 0.83–.92) and test–re-test reliability were good ( r = 0.69), and the results of CFA supported a one-factor model. YP-CORE showed good concurrent validity against two widely used symptom-specific measures ( r = 0.62–0.87). Gender had a moderately strong effect on the scores ( d = 0.67), but the effect of age was not as evident. The measure was sensitive to change, showing a larger effect size ( d = 0.55) than in the BDI-21 and BAI ( d = 0.31–0.50). Conclusions: The results show that the translation of YP-CORE into Finnish has been successful, the YP-CORE has good psychometric properties, and the measure could be taken into wider use in clinical settings for outcome measurement in adolescents.
