Tailored Activity Goals - an Exercise Prescription Study

NCT02560792 | Completed

• 1 other identifier: F31MH079636
• Study Type: interventional
• Target: 101
• Locations: 0 countries
• Sites: N/A

Brief Summary

The primary goal of this study is to determine experimentally the relationship between affective response to exercise and future exercise behavior. A secondary goal is to examine potential mediators and moderators of this relationship, specifically four variables considered to contribute to the volitional control of exercise behavior - planning, attention, resource commitment, and affect regulation. An additional goal is to examine how symptoms of depression might influence the affective response to exercise, and the relationship between affective response to exercise and exercise behavior.

Conditions

Physical Activity; Affect

Outcome Measures

Primary Outcomes (2)

• Days of exercise according to prescription as measured by exercise log

  Number of days of prescribed exercise recorded on exercise log

  7 days

• Days of exercise according to prescription as measured by heart rate monitor

  Number of days of prescribed exercise recorded by heart rate monitor

  7 days

Secondary Outcomes (3)

• Intentions to exercise according to prescription as measured by intention to exercise scale

  5 minutes post-intervention

• Volitional control of exercise: Planning as measured by exercise planning scale

  7 days post-intervention

• Volitional control of exercise: Commitment as measured by commitment to exercise scale

  7 days post-intervention

Other Outcomes (4)

• Positive activated affect as measured by Physical Activity Affect Scale

  5 minutes before, 10 and 20 minutes during, and 5 minutes after intervention

• Negative activated affect as measured by Physical Activity Affect Scale

  5 minutes before, 10 and 20 minutes during, and 5 minutes after intervention

• Tranquility as measured by Physical Activity Affect Scale

  5 minutes before, 10 and 20 minutes during, and 5 minutes after intervention

Study Arms (3)

Positive Affect Condition

EXPERIMENTAL

Participants read that their exercise prescription was a healthy level of intensity for exercise, and then read that most people indicated this level of intensity leads to positive affect. To further encourage participants to think about how the supposed typical affective response might apply to them personally, they were also asked to describe how they thought the exercise might lead to positive feelings.

Behavioral: Positive Affect Condition

Negative Affect Condition

EXPERIMENTAL

Participants read that their exercise prescription was a healthy level of intensity for exercise, and then read that most people indicated this level of intensity leads to negative affect. To further encourage participants to think about how the supposed typical affective response might apply to them personally, they were also asked to describe how they thought the exercise might lead to negative feelings.

Behavioral: Negative Affect Condition

Control Condition

EXPERIMENTAL

Participants read that their exercise prescription was a healthy level of intensity for exercise - affect was not mentioned.

Behavioral: Control Condition

Interventions

Positive Affect Condition BEHAVIORAL

Participants read: "Most people exercising at this intensity say that it feels good, and that it makes them feel energized and more positive, and more relaxed afterwards. Thinking about your exercise prescription, please list the reasons or ways in which you, personally, might expect this exercise to lead to positive feelings, and what specifically about this exercise might make you, personally, feel good."

Positive Affect Condition

Negative Affect Condition BEHAVIORAL

Participants read: "Most people exercising at this intensity say that it doesn't feel very good, and that it makes them feel tired and not so positive, and not very relaxed afterwards. Thinking about your exercise prescription, please list the reasons or ways in which you, personally, might expect this exercise to lead to negative feelings, and what specifically about this exercise might make you, personally, feel bad."

Negative Affect Condition

Control Condition BEHAVIORAL

Participants receive no information about affective response
