Although existing psychoeducational and behavioral interventions have effectively increased positive self-perceptions of aging, often their beneficial effects have been investigated with short follow-ups or faded over time. This may be due to interventions having been delivered at the individual level without sufficient attention to social context, but individuals\u2019 self-perceptions of aging are likely influenced by the age-related beliefs and behaviors of people close to them.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>We aim to deliver a 12-week multicomponent intervention promoting positive self-perceptions of aging and physical activity to investigate (1) whether it promotes significant change in primary (i.e., self-perceptions of aging and physical activity) and secondary (i.e., self-directed and other-directed ageism, subjective views of couple\u2019s joint aging, perceived age-related changes in one\u2019s partner, anxiety and depressive symptoms, physical fitness, and executive function) intervention outcomes; (2) whether observed change in intervention outcomes is greater when the intervention is delivered to couples compared to when it is delivered to one partner alone; (3) the extent to which the effect of the intervention is extended from one partner who undertakes the intervention to the other partner who does not undertake it.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We will adopt a three-arm randomized controlled trial (RCT) design with pre, immediate post-intervention, and three- and six-months follow-up assessments.

In the first group, partners will undertake together the intervention, comprising a psychoeducational and a behavioral component. In the second group, only one partner will undertake the same intervention. In the third\/control group none of the partners will undertake the intervention during data collection. Self-perceptions of aging, physical activity, ageism, subjective views of couple\u2019s joint aging, perceived age-related changes in one\u2019s partner, and anxiety and depressive symptoms will be assessed via questionnaires whereas physical fitness, executive function, and attention will be objectively assessed in person.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This project will provide evidence on whether targeting couples could enhance\/facilitate promotion of positive self-perceptions of aging and physical activity in older age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial registration<\/jats:title>\n                    <jats:p>ClinicalTrials.gov: NCT07113860.
