Background: Despite the widely recognized benefits of physical activity for preventing physical and cognitive decline during aging, global estimates indicate that most older adults do not achieve the recommended amount of physical activity due to a lack of motivation. The current research examined the validity and psychometric properties of the Behavioral Regulation in Exercise Questionnaire (BREQ-3) among older adults. Based on Self-Determination Theory (SDT), the BREQ-3 stands out as one of the most extensively utilized tools among exercise motivation studies. Methods: A sample of older adults (N = 383; M age = 73.2 years, SD age = 7.2) completed the BREQ-3 and the Godin–Shepard Leisure-Time Physical Activity Questionnaire (GSLTPAQ). Results: Confirmatory factor analyses confirmed the six-factor structure postulated by SDT, showing good fit indices (CFI= 0.95; RMSEA = 0.05; SRMR = 0.04) and supporting the full measurement invariance of the scale across sex and age groups (65 to 74 years; over 75 years). The construct and criterion validity of the BREQ-3 was upheld through the latent correlations between its subscales and their correlations with the GSLTPAQ. Conclusions: We demonstrated for the first time the effectiveness of the BREQ-3 in assessing all forms of behavioral regulation proposed by SDT in older adults, suggesting that older adults similarly interpreted the items across sex and age groups.

In the present ecological study, we analyzed the relations of a set of self-efficacy beliefs at work to parameters of diurnal cortisol variation. Specifically, using data collected during two consecutive working days from 166 workers, we tested a mediation model positing social and work-related self-efficacy beliefs as mediators of the relations between self-regulatory emotional self-efficacy beliefs in managing negative emotions and cortisol indicators. Results from the multilevel mediation analyses supported the proposed model for work-related self-efficacy, which resulted as a significant mediator of the relation between self-regulatory emotional self-efficacy beliefs in managing negative emotions and the overall cortisol daily production indexed by computing the area under the curve with respect to the ground. Findings suggest the importance of self-efficacy beliefs for workers' physiological adjustment. Theoretical and practical contributions of the findings are discussed.

Introduction: The present study represents the first systematic review summarizing existing publications on older sexual and gender minority (LGBT+) people's engagement with physical activity (PA) aged 65 and over. Methods: Relevant articles were systematically searched in four scientific databases (i.e., PsychArticles, PsychInfo, Pubmed, and Web of Science) in March 2023. We included original articles published after 1968 with relevant keywords associated with “PA”, “older adults”, and “LGBT+ identity”. Of the 887 records identified, 53 articles were included in the systematic review. Results: Studies were critically reviewed according to participants’ subjectivity considered in the publications: (a) sexual minority (LGB+) identities; (b) sexual and gender minority (LGBT+) identities; (c) transgender and gender-diverse identities; (d) gay and bisexual male identities; and (e) lesbian and bisexual female identities. The most frequent research areas, taking together all the five identity categories considered in the present review, were the differences between LGBT+ people and cis-heterosexual people, the discrimination and homophobia/transphobia in sport-related contexts, and the competent interventions and aging well in LGBT+ older adults. Conclusions: Findings suggest a lack of information regarding PA in older LGBT+ aged 65 and over. Future research should investigate the barriers and enablers of PA in older LGBT+ people. Policy Implications: It is mandatory to promote regular exercise to reduce health disparities between older LGBT+ individuals and their cis-heterosexual counterparts. The policy and environmental implications of the findings for older LGBT+ people are discussed.
