Phase 3: Adolescents (N = 100, age 12–14 years, 44% female) completed the HIIT-SQ twice (1 week apart) to evaluate test–retest reliability. Confirmatory factor analysis of the final six items (mean = 3.43–6.73, SD = 0.99–25.30) revealed adequate fit, χ²(21) = 21, p = .01, comparative fit index = .99, Tucker–Lewis index = .99, root mean square of approximation = .07, 90% confidence interval [.04, .11]. Factor loading estimates showed that all items were highly related to the factor (estimates range: 0.81–0.90). Intraclass coefficients and typical error values were .99 (95% confidence interval [.99, 1.00]) and .22, respectively. This study provides preliminary evidence for the validity and reliability of scores derived from the HIIT-SQ in adolescents.]]> Wed 18 May 2022 12:22:41 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29895 Wed 06 Nov 2019 12:48:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29638 Wed 04 Sep 2019 10:31:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24815 Wed 04 Sep 2019 10:18:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36330 Wed 01 Apr 2020 12:47:03 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50437 Tue 25 Jul 2023 19:15:59 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51131 Tue 22 Aug 2023 15:58:44 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33481 Resistance Training for Teens was evaluated using a cluster RCT in 16 schools located in New South Wales, Australia. Adolescents (N = 508; 14.1 ± 0.5 years; 49.6% female) completed measures of global self-esteem, subjective well-being, and hypothesized mediators (i.e., perceived fitness, resistance training self-efficacy, and autonomous motivation) at baseline (April-June, 2015) and post-intervention (October-December). The school-based physical activity program was delivered by teachers over 10-weeks via Physical Education, co-curricular school sport, or an elective subject known as Physical Activity and Sport Studies, and involved once-weekly fitness sessions and additional lunch-time sessions. Intervention effects and moderator analyses were tested using multi-level linear regression analyses with interaction terms. Multi-level mediation analyses were used to explore potential mediators of changes in well-being outcomes. Results: Intervention effects for self-esteem (ß = 0.05, p =.194) and wellbeing (ß = 0.03, p =.509) were not statistically significant. Moderator analyses showed effects for self-esteem were greater for the overweight/obese subgroup (p =.069 for interaction), and resistance training self-efficacy was a significant mediator of changes in self-esteem (product-of-coefficients [AB] = 0.021, SE = 0.010, 95% CIs = 0.002 to 0.040). No other significant indirect effects were observed. Conclusion: Overall, Resistance Training for Teens did not improve adolescents' self-esteem or subjective well-being. However, our mediation findings lend support to resistance training self-efficacy as a mechanism explaining the positive effect of resistance training on self-esteem.]]> Tue 01 Sep 2020 14:18:41 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31351 Thu 30 Jan 2020 10:58:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25396 Thu 03 Feb 2022 12:20:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45542 N = 485, ≥ 65 years) were randomised to similar age same gender (SASG), similar age mixed gender (SAMG), or “standard” mixed age mixed gender (MAMG) group-based exercise programs. Flourishing and stigma consciousness were assessed on six occasions during the 24-week intervention and represented secondary trial outcomes. Multilevel growth models examined the effects of the interventions on flourishing and stigma consciousness over time. Results: Participants in the SASG and SAMG conditions demonstrated, on average, higher levels of flourishing, relative to the MAMG condition, over the course of the 24 weeks (p < .05). Additionally, participants demonstrated lower levels of age- and gender-related stigma consciousness in both the SASG and SAMG conditions relative to the MAMG condition (p < .05). No time by group interaction effects were observed for either flourishing or stigma consciousness. Conclusions: The results provide some support for the utility of group exercise programs, informed by self-categorisation theory, to enhance psychological flourishing and reduce stigma consciousness among older adults.]]> Mon 31 Oct 2022 17:47:03 AEDT ]]>
