Inspired by a learning health system approach, a hybrid paper/electronic data capture platform was developed at PEPP-Montreal, an early psychosis program, gathering data on patient socio-demographics, symptoms, functioning, pathways to care, substance use, and medication monitoring. This article evaluates the year-one deployment of this innovative infrastructure (2022−2023). The novel 2022 hybrid infrastructure was compared with the 2016 paper-based version, using the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). Phase 1 identified evidence-based clinical measures including patient-reported, clinician-reported, and evaluator-reported outcomes, while phase 2 further streamlined and implemented the electronic data capture platform. Continuous data collection through the platform was deployed at six time points. Results included: <em>Reach</em>: <em>N</em> = 53/81 patients used paper/electronic data for their year-one service evaluation. <em>Effectiveness:</em> The automated, hybrid paper/electronic protocol optimized data management. <em>Adoption:</em> Rates of electronic patient-reported outcomes were higher in 2022–2023 than 2016–2017 (paper version). Completion rates for clinician-reported outcomes were highest at baseline (year-one). <em>Implementation/maintenance</em>: Barriers and facilitators, essential adaptations, and sustainable impacts were identified. Using electronic, measurement-based data collection accelerates feedback closer to real time and alignment with learning health system principles. Implementing the hybrid data collection platform at PEPP-Montreal provided valuable insights into using measurement-based care to inform quality of services.

The clinical high-risk (CHR) period provides an important time for investigating early mechanisms, and their relation to psychosis vulnerability. However, our understanding of subjective emotional experiences in this critical population, particularly contextualized within social interactions, is limited. To address this gap, the present study aimed to evaluate subjective emotional experiences in CHR youth (12−30) using an experimental dyadic interaction paradigm. The sample included 148 individuals, 36 CHR-Partner dyads and 41 Control-Partner dyads, who engaged in three 10-min dyadic interactions (i.e., neutral, conflict, and pleasant). Following each conversation, participants reported the intensity of their positive and negative emotional experiences. Participants also completed a series of structured clinical interviews. CHR youth reported greater negative emotional experiences following pleasant conversations than control youth (U(74) = 533.5, <em>p</em> = 0.035).
