Exploration of psychometric properties of the Italian version of the Core Young Person’s Clinical Outcomes in Routine Evaluation (YP-CORE)

There is an increasing need of outcome measures for young people suitable to evaluate treatments and routine settings. However, measures must show suitable psychometric characteristics for such use. This is the first psychometric evaluation of the Italian version of the Core Young Person Clinical Outcomes in Routine Evaluation (YP-CORE). Data are reported for a clinical sample, aged 11-17 (n=175) and non-clinical sample, aged 11-17 (n=206). Analyses included acceptability, confirmatory factor analysis, internal reliability, influence of gender and age on cutoff scores and reliable change. The YP-CORE acceptability was good, with a very high completion rate (98.7% fully completed). Internal consistency was good: the overall Cronbach’s alpha value (α) equal to 0.75 (95% confidence interval=0.69-0.80). The measure was sensitive to change (Cohen dz=1.35). The Italian version of the YP-CORE showed acceptable psychometric properties is suitable for use in services for young people as a change/outcome measure.
