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.

Arm Intervention/treatment
Experimental: Dyadic planning intervention
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 intervention
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.

Behavioral: General motivational treatment
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.

Active Comparator: Individual planning intervention
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 intervention
Target persons form action plans on their own.

Behavioral: General motivational treatment
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.

Active Comparator: No-planning control condition
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
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.




Primary Outcome Measures :
  1. Physical activity [ Time Frame: six weeks post intervention ]
    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.


Secondary Outcome Measures :
  1. Cardiorespiratory fitness [ Time Frame: one year post intervention ]
    Cardiorespiratory fitness in target persons and partners is measured by a 2-km walking test. Using the duration and heart-rate of the 2-km walking test, as well as age, sex and BMI, an index is calculated that represents the cardiorespiratory fitness measure which can be compared to norm values.

  2. Dyadic action planning [ Time Frame: one year post intervention ]

    Dyadic action planning of daily physical activity will be assessed in target persons and partners by questionnaire.

    Couples' own regular dyadic action planning of target persons' and partners' daily physical activity during the past seven days will be assessed by four items using the stem "I have made a detailed plan together with my partner regarding ..." followed by (1) "when", (2) "where", (3) "how", and (4) "how often to be physically active" adapted from earlier research on dyadic planning of pelvic-floor training (Burkert et al., 2011). Response options range from 1 = "does not apply at all" to 6 = "applies exactly".


  3. Individual action planning [ Time Frame: one year post intervention ]

    Individual action planning of daily physical activity will be assessed in target persons and partners by questionnaire.

    Participants' own regular individual action planning of daily physical activities during the past seven days will be measured using four items using the stem "I have made a detailed plan regarding ..." followed by (1) "when", (2) "where", (3) "how", and (4) "how often to be physically active" (Scholz et al., 2007). Response options range from 1 = "does not apply at all" to 6 = "applies exactly".


  4. Physical activity [ Time Frame: one year post intervention ]
    Partners' daily physical activity will be objectively assessed in a parallel manner at the same four measurement occasions (T0, T2, T3, and T7). At each assessment, accelerometer devices will be worn for 7 days. Accelerometers will be worn by target persons and partners, providing data on activity counts, steps taken, activity intensity levels, and METs.

  5. Physical activity [ Time Frame: one year post intervention ]
    Self-reported physical activity in target persons and partners is assessed by a combination of the Office in Motion questionnaire (OIMQ; Mäder et al., 2006) complemented by items of the Physical Activity Frequency Questionnaire (PAFQ; Bernstein, Sloutiskis, Kumanyika, Sparti, Schutz, & Morabia, 1998). This combined measure provides detailed information on time spent on physical activities of moderate and vigorous intensity within the past 7 days, covering the domains of transportation, occupational activity, household and yard work activities, and leisure-time physical activity.

  6. Individual action control [ Time Frame: one year post intervention ]
    Physical activity-related individual action control during the past seven days will be assessed by 6 items addressing the three action control facets of comparative self-monitoring, awareness of standards, and self-regulatory effort (e.g., "During the last seven days I have really tried to be regularly physically active"; Sniehotta et al., 2005). Response options range from 1 = "does not apply at all" to 6 = "applies exactly".

  7. Received partner support [ Time Frame: one year post intervention ]
    Physical activity-related received partner support during the past seven days will be assessed using 6 items from the Berlin Social Support Scales (Schulz & Schwarzer, 2004) adapted to the domain of physical activity (e.g., "My partner helped me to be physically active"). Response options range from 1 = "does not apply at all" to 6 = "applies exactly".

  8. Provided partner support [ Time Frame: one year post intervention ]
    Physical activity-related provided partner support during the past seven days will be assessed using 6 items from the Berlin Social Support Scales (Schulz & Schwarzer, 2004) adapted to the domain of physical activity. These items will mirror the received support items (e.g., "I helped my partner to be physically active"). Response options range from 1 = "does not apply at all" to 6 = applies exactly".

  9. Received partner control [ Time Frame: one year post intervention ]
    Physical activity-related received partner control during the past seven days will be assessed with a measure adapted from Lewis and Rook (1999). The scale consists of 8 items (e.g., "My partner pressured me to be physically active") measuring received partner control related to physical activity. Response options range from 1 = "does not apply at all" to 6 = "applies exactly".

  10. Provided partner control [ Time Frame: one year post intervention ]
    Physical activity-related provided partner control during the past seven days will be assessed in accordance with Lewis and Rook (1999) by 8 items (e.g., "I pressured my partner to be physically active") applied to physical activity. Response options range from 1 = "does not apply at all" to 6 = "applies exactly".
