Detailed Description
Patients discharged from the Ex-DHF trial were recruited from June 2013 to December 2015 and offered participation in a controlled add-on pilot study. The treatment group (n=19) received 5 sessions of MI, each lasting 15-30 min over 6 months to enhance physical activity.
For the first two and the last sessions participants met with the psychologist-counsellor face-to-face for about 45 minutes. The remaining three sessions could be conducted via telephone or face-to-face, depending on participants' preferences, and typically lasted 15-30 minutes. Per study protocol, counsellors (physicians and psychologists trained in motivational interviewing) assisted the participants in: (1) Setting goals for their physical activity; (2) developing a plan to increase physical activities; (3) setting specific plans for the implementation of the plan; and (4) overcoming possible barriers. Participants were also asked to keep track of their daily physical activity in a diary, which counsellors then discussed with them during the sessions.
After patients had given their written informed consent, counsellors assessed all participants via structured interview and self-rating scales. At baseline only, sociodemographic information was recorded.
At baseline and at the final 6-month visit participants' motivation to be physically active in the upcoming weeks was assessed using the SSK-scale ("Sportbezogene Selbstkonkord" = sports-related self-concordance, Seelig and Fuchs 2006) to assess the self concordance of sport- and exercise-related goals.
The kind and extent of patients' daily physical activity was recorded using patient diaries. At baseline and 6 months we also conducted a symptom-limited cardiopulmonary exercise test on a bicycle ergometer, in order to assess changes in maximum rate of oxygen consumption during the last 30 seconds before the termination of the exercise (peak oxygen consumption (VO2 [ml/min/kg])) as measure of maximal exercise capacity. Participants also completed the 6-minute walk test on flat surface (6-MWT) as an additional parameter to assess submaximal exercise capacity.
Additionally, at the 6-month assessment, intervention participants filled out a questionnaire about their subjective evaluation of the counseling program.
The control group (n=20) received usual care.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Adherence to intervention
Time Frame: Over 6 month intervention period
|
To evaluate the feasibility of motivational counseling to enhance physical activity patients´ adherence to appointments is assessed as number / percentage of sessions attended
|
Over 6 month intervention period
|
Patient acceptance of intervention
Time Frame: At 6-month assessment
|
To assess how patients evaluate the Intervention, i.e. receiving motivational counseling, they were asked to fill in evaluation sheets
|
At 6-month assessment
|
Effectiveness (peak VO2)
Time Frame: Change from baseline to 6-month assessment
|
Changes in the maximal exercise capacity (peak VO2) during a symptom-limited cardiopulmonary exercise test on a bicycle ergometer.
|
Change from baseline to 6-month assessment
|
Effectiveness (6-minute walk distance)
Time Frame: Change from baseline to 6-month assessment
|
Six-minutes walking distance

Change from baseline to 6-month assessment

Other Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Motivation
Time Frame: Change from baseline to 6-month assessment.
|
Participants' motivation to be physically active was registered using the SSK (Sports-related self-concordance) scale.
The self-concordance score is computed by subtracting the sum of the introjected and extrinsic motivation from the sum of the intrinsic and identified motivation subscales, with resulting scores ranging from -10 to +10 (higher value = higher self-concordance)
|
Change from baseline to 6-month assessment.

Physical activity
Time Frame: Change from baseline to 6-month assessment.
|
The kind and extent of patients' daily physical activity was recorded using patient diaries
|
Change from baseline to 6-month assessment.
