Attendance analysis in a phase 3 cardiovascular rehabilitation program: can behaviour regulation in exercise predict long-term attendance?

Abstract Funding Acknowledgements Type of funding sources: None. Background After a phase II cardiovascular rehabilitation (CR) program, cardiovascular disease (CVD) patients ideally continue to a phase III long-term CR program. Enrolment, attendance rates and barriers are well established for phase II or short-term CR programs (≤ 12 weeks). However, keeping CVD patients motivated and with high attendance rates (≥ 80%) in a long-term CR program (over 6 months) is more challenging. Self-Determination Theory states that more internalized types of behaviour regulation lead to feelings of self-determination and a higher behavioural adherence. Therefore, more studies analysing attendance rates and behaviour regulation of CVD patients in long-term CR programs are needed. Purpose To compare the attendance of CVD patients enrolled in a long-term CR community-based program between 3, 6 and 12 months and to assess if behavioural regulation in exercise questionnaire (BREQ-2) can predict long term attendance. Methods Patients with CVD attending for, at least, 6 months a phase III community-based CR program were selected. Enrolled patients chose to attend 60 minutes exercise CR sessions either 3 or 2 times/week. Attendance rates were calculated at 3 months, 6 months and 12 months of program completion dividing the number of sessions attended by the number of sessions planned. When admitted to the program, each patient was asked to answer BREQ-2 (19 items, 5-point lickert-type scale, 5 groups: amotivated, external, introjected, identified and intrinsic). One way ANOVA for repeated measures, paired sample t test and pearson correlations were used. Results One hundred and eighteen CVD patients (61 ± 9 years; 78.8% male; 85% with coronary artery disease) completed at least 6 months of CR exercise sessions. Attendance rates decreased significantly from 3 months to 6 months (73.38 ± 18.09% vs 68.14 ± 17.15%, p-value
