Brief Summary

Regular physical activity is one prominent health-protective behaviour which might increase with the help of self-regulatory strategies such as action planning. The aim of this randomised controlled trial is to examine changes in daily moderate physical activity in couples following (a) a dyadic planning intervention, (b) an individual planning intervention or (c) a no-planning control condition. Changes in daily physical activity will be examined over a period of one year. It is assumed that target persons from couples receiving a dyadic planning intervention will show greater increases in daily physical activity than target persons from couples receiving an individual planning intervention. For couples receiving a dyadic planning intervention or an individual planning intervention, it is hypothesized that target persons will show higher increases in daily physical activity than target persons from couples participating in the no-planning control condition.

Outcome Measures

Primary Outcomes (1)

  • Physical activity

    Target persons' change in moderate daily physical activity (in minutes) from baseline (T0) until 6-weeks (T3) following the intervention will be assessed by an accelerometer device. At each assessment, accelerometer devices will be worn for 7 days.

    six weeks post intervention

Secondary Outcomes (10)

  • Cardiorespiratory fitness

  • Dyadic action planning

Study Arms (3)

Dyadic planning intervention

EXPERIMENTAL

A general motivational treatment is provided to each participant. For randomly assigned couples, randomly selected target persons form action plans to increase daily physical activity together with their partners.

Behavioral: Dyadic planning interventionBehavioral: General motivational treatment

Individual planning intervention

ACTIVE COMPARATOR

A general motivational treatment is provided to each participant. For randomly assigned couples, target persons form action plans individually to increase daily physical activity and partners receive a distraction task.

Behavioral: Individual planning interventionBehavioral: General motivational treatment

No-planning control condition

ACTIVE COMPARATOR

A general motivational treatment is provided to each participant. For randomly assigned couples, target persons do not receive instructions for action planning, but perform a distraction task together with their partners.

Behavioral: General motivational treatment

Interventions

Dyadic planning interventionBEHAVIORAL

Dyadic planning refers to creating together with a partner if-then plans on when, where, and how the individual target person will implement a new behaviour.

Dyadic planning intervention
Individual planning interventionBEHAVIORAL

Target persons form action plans on their own.

Individual planning intervention
General motivational treatmentBEHAVIORAL

Both partners are asked to read a brochure that aims at enhancing their motivation to increase levels of moderate physical activity. They respond to a quiz afterwards.
