ABSTRACT
Objective: This review aimed to summarize longitudinal research about the interplay between sleep, mental health, and positive well-being in adolescents. Method: Multiple search strategies were applied until 28th January 2023 to identify relevant research published in peer-reviewed journal articles or available grey literature. A final set of 63 studies were included in the systematic review and 42 in the meta-analysis. Results: Results highlighted that long sleep duration, good sleep quality, and low insomnia symptoms were bidirectionally related to lower internalizing (Sleep T1 → Internalizing symptoms T2: r = -.20, p < .001; Internalizing symptoms T1 → Sleep T2: r = -.21, p < .001) and externalizing (Sleep T1 → Externalizing symptoms T2: r = -.15, p < .001; Externalizing symptoms T1→ Sleep T2: r = -.17, p < .001) symptoms, and to higher levels of psychological well-being (Sleep T1 → Psychological well-being T2: r = .15, p < .001; Psychological well-being T1 → Sleep T2: r = .15, p < .05). Moreover, good sleep was positively related to higher subjective well-being at a later time point (r = .18, p < .001). Conclusions: Overall, these findings suggest a bidirectional relation between different aspects of sleep, mental health, and positive well-being.(AU)

PURPOSE: More Than Words® (MTW) is a caregiver-mediated intervention program led by a speech-language pathologist (SLP) who teaches caregivers strategies to support their autistic child's early social communication and play development. The program includes group sessions composed of multiple families with children of varying profiles. We explored whether caregiver experiences and perceived outcomes of the virtual MTW program differed depending on the child's age and social communication stage. METHOD: As part of a program evaluation of virtual MTW delivered to over 2,000 families in Ontario, Canada, between 2020 and 2021, we randomly selected 31 families across four social communication stages and two age groups using stratified sampling (n = 4, in all but one subgroup). The Final Reflection and Evaluation form was analyzed both qualitatively and quantitatively, and a modified RE-AIM framework guided our analyses, including theme development. RESULTS: Child attributes did not appear to impact caregivers' experiences, but perceived child skill improvements varied by children's social communication stage. The majority of caregivers reported changes in how they interact with their child. Four themes emerged: (a) perceived child skill improvements differed by social communication stage, (b) caregivers gained new knowledge and strategies regardless of child attributes, (c) SLPs effectively managed families' individual needs, and (d) program components were appropriate for a variety of families. CONCLUSIONS: Findings suggest that the content taught in the MTW program was relevant for a variety of children, including those beyond the program's intended age of 5 years and under. Grouping families of children with varying profiles does not appear to negatively influence caregivers' experiences or perceived outcomes.

ABSTRACT
Chloroplast movement rapidly ameliorates the effects of suboptimal light intensity by accumulating along the periclinal cell walls, as well as the effects of excess light by shifting to the anticlinal cell walls. These acclimation responses are triggered by phototropins located at the plasma membrane and chloroplast envelope. Here, we used a recently developed non-invasive system sensitive to very small changes in red light leaf transmittance to perform long-term continuous measurements of dark-light transitions. As a model system, we used variegated Pelargonium zonale leaves containing green sectors (GS) with fully developed chloroplasts and achlorophyllous, white sectors (WS) with undifferentiated plastids, and higher phototropin expression levels. We observed biphasic changes in the red-light transmittance and oscillations triggered by medium intensities of white light, described by a transient peak preceded by a constant decrease in transmittance level. A slight change in red-light transmittance was recorded even in WS. Furthermore, the chloroplast position at lower light intensities affected the rapid light curves, while high light intensity decreased saturated electron transport, maximum quantum efficiency of photosystem II, and increased non-photochemical quenching of chlorophyll fluorescence and epidermal flavonoids. Our results extend the knowledge of light-dependent chloroplast movements and thus contribute to a better understanding of their role in regulating photosynthesis under fluctuating light conditions.
