63 Self-efficacy for health-related behavior change PART 1 later in the DECIDE study. However, as self-efficacy did not change in this 3-months follow up, we only used baseline data in this study. The assessment included self-reported questionnaires on self-efficacy, fear, social support, depressive symptoms, health-related behavior and social support. Furthermore, all patients underwent a cognitive assessment. The following questionnaires were completed: · Self-efficacy was measured with the self-efficacy scale, a 7-item scale with scores that range from 1 to 5. [30] Higher values indicate more confidence to carry out the behavior necessary to reach the desired goal. Cronbach’s α of the self-efficacy questionnaire was 0.75. This scale has been used successfully before in in vascular patients. [10, 16, 31, 32] · Fear was assessed with 8 questions. Patients were asked on a scale of 1 to 5 how nervous they are when thinking of getting another stroke, how upset they get, depressed or jittery, if their heart beats faster, an if they feel uneasy or anxious. [33] · Social support was evaluated with the aspects of Active engagement, Protective buffering, and Overprotection (ABO) social support questionnaire for Dutch coronary heart disease patients. [34] This questionnaire includes 5 statements about active involvement, 8 statements concerning protective buffering, and 6 about overprotection, of which respondents can respond on a 5-point scale, ranging from (0) ‘very often’ to (4) ‘never’. · Depressive symptoms were assessed with the CES-D (centre for Epidemiologic Studies Depression Scale) for both depression and anxiety. [35, 36] Higher scores indicate more depressive symptoms. · Physical activity was assessed with the International Physical Activity Questionnaire short (IPAQ-S) questionnaire. Patients were asked to report activities performed for at least 10 minutes during the last 7 days, and time spent in physical activity performed across leisure time, work, domestic activities, and transport at each of 3 intensities: walking, moderate, and vigorous. [37] We used reported minutes of moderate and vigorous physical activity to calculate a total physical activity score of minutes a day. As included patients had a mRS score of 2 or less they were able to walk without assistance and look after their own affairs without assistance. · Dietary behavior was assessed with the short Food Frequency Questionnaire (FFQ). This 14-item scale assesses the intake of saturated fatty acids, unsaturated fatty acids,
