Abstract P130: Examining Relationships between Stroke Risk Perception and Locus of Control: The SWIFT Community Study
Introduction: We have reported fatalism to be associated with an overestimation of risk of stroke leading to maladaptive behaviors. The purpose of this pilot study was to better understand the interplay between Chance Health Locus of Control (CHLC) and perceived risk of stroke.
Methods: The Stroke Warning Information and Faster Treatment Community study was a randomized stroke preparedness intervention, which prospectively enrolled stroke-free community members from 30 community organizations. Baseline demographics were assessed by interviewer administered questionnaires. CHLC was assessed through phone administered Multidimensional Health Locus of Control Scale (score range 6-36) at 1 year follow-up. Risk perception was measured on a scale of 0 (unlikely) - 10 (likely) for likelihood of having a stroke or catching a cold in 10 years. We calculated the univariate distribution of the CHLC and stroke risk perception as well as the distribution of these measures across age, sex, race-ethnicity, education, and self-reported hypertension using ANOVA. We assessed the association between CHLC with stroke and cold risk perception using odds ratios.
Results: This pilot included 52 stroke-free community residents; mean of 65 yrs; 92% female; 46% White, 23% Black, 25% Hispanic. The mean CHLC score 17.1 (SD 7.2); median 16.5 (IQR 12-21.5). While not significant, women (16.6) and those with more than a high school degree (15.6) had a lower mean CHLC score than men (20), and persons with a HS degree or less (18.7; p=0.12). CHLC score did not significantly differ by age, sex or self-reported hypertension. Mean perceived stroke risk was 5 and did not vary by demographics. Mean cold score was 6.3 (SD 3.7); median 8 (IQR 3-10). Perception of cold risk varied by race and education; Hispanic (m=8.9) and Whites (m=6.9) more accurately portrayed risk of catching a cold than Blacks (m=2.7, p=0.006) and more than HS degree (7.41) more accurately estimated risk of cold than those with HS degree or less(4.9, p=.06). We did not observe an association between CHLC and perceived risk of stroke (OR = 0.72, 95%CI = 0.24, 2.22) or cold (OR = 1.21, 95%CI = 0.36, 4.01).
Discussion: In this small pilot analysis we report no association between CHLC and perceived risk of stroke. Further even those who accurately perceived their risk of colds still have trouble grasping stroke risk. Further research is needed.
