OBJECTIVE: The project aims at investigating of the effects of three types of planning (individual planning, collaborative planning, and dyadic planning) on physical activity among dyads.The influence of three planning interventions are compared with an active control condition, including physical activity education.
PARTICIPANTS: The effects of the interventions are evaluated among dyads of two adults (partner-partner dyads). Adults forming dyads (e.g. two romantic partners, two relatives, two co-workers, two friends) who are in regular contact for at least one year will be enrolled. A minimum of 50 dyads enrolled into the each arm of the trial (a total of 200 dyads). The interventions consist of six planning sessions.
DESIGN: The dyads are randomly assigned to one of four experimental conditions. The assessment of the main and secondary outcomes is conducted at the baseline, at 1 week after the first intervention session, at post-intervention (after six intervention sessions are completed), and at 6-, and 12-month follow-ups.
OUTCOMES: Physical activity constitutes the main outcome, whereas health-related quality of life (HRQOL), body mass index, and sedentary behavior as well as the self-regulatory strategy called the use of planning (individual, dyadic and collaborative) are secondary outcomes.
Individual planning (also known as implementation intentions or action and coping planning) is a regulatory strategy, which refers to making plans on when, where, and how to perform an intended behavior. In dyadic planning, a target person is setting plans together with a partner on when, where, and how the target person will individually engage in behavior change. The concept of dyadic planning differs from the conceptualization of collaborative plans, where two individuals make plans on how to enact a behavior together.
The study will evaluate the effects of a short-term planning intervention. The intervention includes a total of six sessions: two face-to-face sessions with the experimenter (delivered over two weeks) and three sessions delivered over phone (over the following three weeks), one face-two-face session (delivered at one month after the third session delivered over the phone). The delivery has an individual format (the experimenter + the dyad). The total time from first to sixth session is 2 months. The setting for the interventions will include physician's offices and participant's home. The same format, schedule, delivery, and setting will be used for conducting active control group procedures.
University of Social Sciences and Humanities, Warsaw is the lead sponsor of 24 studies on the registry; 10 are open to participants now.

Exclusion Criteria:
The planning materials and forms have sections: (a) information on the importance of planning, including examples of how planning works and what it affects, (b) instructions of what should be included in a good plan (the when, where, and how components), (c) formulating action and coping plans. Action plans (referring to when, when, and how the individual will act) as well as coping plans (referring to how to overcome potential difficulties, risky situations or temptations to not engage in physical activity) will be formed. Each participant will form their plans individually, without consulting the dyadic partner, but discussing the plans with the experimenter.

The planning materials and forms have sections: (a) information on the importance of planning, including examples of how planning works and what it affects, (b) instructions of what should be included in a good plan (the when, where, and how components), (c) formulating action and coping plans. Action plans as well as coping plans will be formed. Both partners in the dyad jointly form one plan. This jointly developed plan is discussed with the experimenter. The plan focuses on physical activity of only one person in the dyad. This target person will be selected jointly by the participants if both participants are healthy. If one participant has a chronic disease, e.g. diabetes or a cardiovascular disease, the plans are formed for the person with a disease.
Behavioral: Dyadic Planning · Behavioral: Education
The planning materials and forms have sections: (a) information on the importance of planning, including examples of how planning works and what it affects, (b) instructions of what should be included in a good plan (the when, where, and how components), (c) formulating action and coping plans. Action plans and coping plans will be formed. Both partners in the dyad jointly form one plan. This jointly developed plan is discussed with the experimenter. The plan focuses on physical activity of both persons within the dyad (both partners) and include some plans for joint physical activity.
Behavioral: Collaborative Planning · Behavioral: Education
The education materials address physical activity and healthy nutrition guidelines for age groups and chronic disease. Participants receive a set of educational materials about types of physical activity (PA), PA intensity, exercise calorie expenditure, strength and endurance training, stretching, and general nutrition guidelines in terms of meal composition, and nutrients, meal frequency. The materials exclude any planning statements. The education is delivered by the experimenter to a partner-partner dyad and discusses individual guidelines for both dyadic partners.
Behavioral: Education
Participants are filling in the planning forms, referring to their individual physical activity. Both members of the dyad form their own, interdependent plans. The following behavior change techniques (BCT) are included in the planning intervention protocol: action planning, barrier identification, prompting self-talk, relapse prevention/coping planning. Applications of all BCT included references to planning.
Participants are filling in the planning forms jointly. Planning refers to physical activity of only one person in the dyad. The other person in the dyad is actively participating in forming plans by the target person. The following BCT are included in the planning intervention protocol: action planning, barrier identification, prompting self-talk, relapse prevention/ coping planning. Applications of all BCT included references to planning.
Participants are filling in the planning forms jointly. Planning refers to physical activity of both persons in the dyad. Physical activity may be performed jointly by both persons in the dyad. The following BCT are included in the planning intervention protocol: action planning, barrier identification, prompting self-talk, relapse prevention/ coping planning. Applications of all BCT included references to planning.
The education group participants receive extended physical activity and healthy nutrition education program. The education includes: (1) the guidelines for physical activity and healthy nutrition, tailored to age and health status of the participants, (2) the examples of exercises and their metabolic equivalent; (3) information about healthy body mass and body composition.
Physical activity
Accelerometry: ActiGraph (the model: wGT3X-B)
Time frame: Change from baseline physical activity at 8 months
Health-related quality of life (HRQOL)
WHOQOL--BREF Questionnaire (Skevington et al., 2004)
Time frame: Change from baseline HRQOL at 8 months
The use of planning
The self-reported use of planning questionnaire (individual, dyadic and collaborative), based on Luszczynska (2006)
Time frame: Change from baseline use of planning at 2 months
Body mass index (BMI)
Certified and standardized body weight scales (Beurer; European Union safety certificate; measurement error \< 5%) and measuring rods will be used. Body mass index will be calculated using the following formula: body weight \[in kg\] divided by a square of body height \[in meters\]. Body weight will be recorded in kilograms and body height will be recorded in meters.
Time frame: Change from baseline BMI at 8 months
Physical activity
The International Physical Activity Questionnaire (IPAQ) (Craig et al., 2003); open-ended questions indicating the minutes and the number of occasions of physical activity behavior per week; higher scores represent better outcome
Time frame: Change from the baseline physical activity at 8 months
Habitual physical activity
Self-reported habit index questionnaire for physical activity (based on Gardner et al., 2012)
Time frame: Change from baseline habitual physical activity at 8 months
Habitual sedentary behavior
