Brief Summary

Engaging in regular physical activity during midlife is a key lifestyle behavior associated with reduced risk for Alzheimer's disease and related dementias (AD/ADRD). Yet nearly half of midlife adults (48%) do not meet national physical activity guidelines. The purpose of this mechanistic trial is to identify effective goal setting techniques to enhance psychosocial processes of self-regulation for the successful promotion of PA and adherence to national PA guidelines among midlife adults, with the long-term goal of reducing AD/ADRD risk

Outcome Measures

Primary Outcomes (3)

  • Change in accelerometer-measured moderate-to-vigorous intensity physical activity from baseline to 6- and 9-months

    Participants will wear wrist-worn ActiGraph GT9X Link Activity monitors the activity monitor on their non-dominant wrist during all waking hours for 7 consecutive days to provide an assessment of usual activity.

    Assessed at baseline, 6-months, 9-months

  • Change in Fitbit-assessed moderate-to-vigorous intensity physical activity

    Participants will wear a wrist-worn Fitbit activity monitor daily throughout the 9-month intervention.

    Assessed daily up to 9-months

  • Change in self-reported moderate-to-vigorous intensity physical activity from baseline to 6- and 9-months

    Self-reported minutes per week of moderate-to-vigorous physical activity assessed by the 7-day Physical Activity Recall.

    Assessed at baseline, 6-months, 9-months

Secondary Outcomes (5)

  • Change in physical activity self-regulation from baseline to 6- and 9-months

    Assessed monthly up to 9-months

  • Change in physical activity behavioral strategies from baseline to 6- and 9-months

    Assessed monthly up to 9-months

  • Change in physical activity self-efficacy from baseline to 6- and 9-months

    Assessed monthly up to 9-months

  • Change in general self-regulation from baseline to 6- and 9-months

    Assessed monthly up to 9-months

  • Change in General Self-Efficacy from baseline to 6- and 9-months

    Assessed monthly up to 9-months

Other Outcomes (18)

  • Change in immediate verbal memory from baseline to 6- and 9-months

    Assessed at baseline, 6-months, 9-months

  • Change in delayed verbal memory from baseline to 6- and 9-months

    Assessed at baseline, 6-months, 9-months

  • Change in visual memory from baseline to 6- and 9-months

    Assessed at baseline, 6-months, 9-months

  • +15 more other outcomes

Study Arms (4)

Static weekly physical activity goal of 150 minutes/week

EXPERIMENTAL

Participants will receive a physical activity action planning intervention and assigned a static weekly physical activity goal of 150 minutes/week of moderate-intensity activity; action planning sessions will focus on the participant achieving this weekly goal.

Behavioral: Physical Activity

Incremental weekly physical activity goal increase

EXPERIMENTAL

Participants will receive a physical activity action planning intervention and assigned a weekly physical activity goal that is 20% greater than the level of moderate-intensity physical activity performed the previous week; action planning sessions will focus on the participant achieving their assigned goal.

Behavioral: Physical Activity

Self-selected weekly physical activity goal

EXPERIMENTAL

Participants will receive a physical activity action planning intervention and will self-select their own moderate-intensity physical activity goal each week; action planning sessions will focus on helping participants achieve their self-selected goal.

Behavioral: Physical Activity

No stated weekly physical activity goal (comparison group)

EXPERIMENTAL

Participants will receive a physical activity action planning intervention that does not include explicitly stated physical activity goals to achieve.

Behavioral: Physical Activity

Interventions

Theory-driven behavioral physical activity promotion intervention.

Incremental weekly physical activity goal increaseNo stated weekly physical activity goal (comparison group)Self-selected weekly physical activity goalStatic weekly physical activity goal of 150 minutes/week
