NCT07553130
Major depressive disorder (MDD) and anxiety are increasingly prevalent among university student populations, yet early detection remains reliant on psychometric instruments tied to diagnostic criteria (e.g., PHQ-9, GAD). Emerging evidence suggests that depression affects both the acoustic properties and content of speech, making speech analysis a promising candidate as a digital biomarker for early screening. This study evaluates the validity of acceXible, a speech-based machine learning platform, for the detection and monitoring of depression and anxiety in the student population of the Benemérita Universidad Autónoma de Puebla (BUAP), Mexico. AcceXible captures spontaneous speech through open-ended interview tasks and applies automated acoustic and linguistic analysis. The primary objective is to evaluate the validity of the acceXible spontaneous speech analysis system for depression and anxiety screening, assessed against the PHQ and GAD scales as reference standards. Secondary objectives include examining associations between speech-derived variables and other study measures, evaluating participant engagement with digital mental health resources, assessing user satisfaction with the platform, and analyzing longitudinal changes in scores across follow-up assessments.
NCT07551180
The purpose of this randomized controlled trial is to evaluate whether a structured mandala activity program can reduce anxiety and improve emotional and psychological well-being in adolescents who have a sibling with special needs. Adolescents in this group may experience emotional difficulties because of the demands and challenges associated with having a sibling who requires special care and support. However, supportive and accessible interventions for these adolescents are limited. In this study, eligible participants will be randomly assigned to either an intervention group or a control group. The intervention group will participate in a structured mandala activity program, while the control group will not receive this program during the study period. Anxiety and emotional and psychological well-being will be assessed before and after the intervention using standardized measurement tools. The main question of this study is whether participation in the mandala activity program leads to better mental well-being outcomes compared with the control group. The findings may help determine whether mandala-based activities can be used as a simple, supportive, and non-pharmacological approach for adolescents who have a sibling with special needs.
