Additional participants (n = 20) were recruited to compute test–retest reliability. Four of seven constructs correlated significantly with sleep hygiene practice (r = −0.17 to −0.36). The scales generally displayed unidimensional component structures. Internal consistency was good to excellent (α = 0.76–0.92). Test–retest reliability was good to excellent (ICC = 0.61–0.84). Though satisfactory, these findings warrant replication in larger samples.]]> Tue 03 May 2022 16:53:32 AEST ]]> Development and evaluation of a mobile health intervention to improve physical activity and sleep health in adults: the Synergy Study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36159 Mon 26 Oct 2020 12:03:39 AEDT ]]> Examining mediators of intervention efficacy in a randomised controlled m-health trial to improve physical activity and sleep health in adults https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47188 d = 0.48, 95% CI: -2.26, -0.33, p = 0.009) and sleep hygiene (d = 0.40, 95% CI: -3.10, -0.19, p = 0.027). Differences in MVPA were not significant (d = 0.24, 95% CI: -35.53, 254.67, p = 0.139). Changes in MVPA were mediated by self-efficacy, perceived capability, environment, social support, intentions and planning, some of which showed inconsistent mediation (suppression). None of the hypothesised psychosocial factors mediated sleep outcomes. Changes in sleep hygiene mediated changes in sleep quality. Conclusions: Several psychosocial factors mediated changes in physical activity but not in sleep outcomes. Mediation effects of sleep hygiene on sleep quality highlight the importance of providing evidence-based strategies to improve sleep quality.]]> Fri 30 Jun 2023 10:17:36 AEST ]]>
