- Abstract
- "Although a multitude of preventative programs have been utilised worldwide to modify cardiovascular risk factors, none have included internet based interventions. Study 1 aimed to compare internet based (n = 21), face-to-face (n = 27), and combined (n = 21) treatment groups with a naturally occurring control group (n = 24) on physiological, psychological, and lifestyle risk variables for cardiovascular disease across 6-months, and to determine if there were relationships between changes in the psychological and physiological variables over time. Results indicated that the internet based group had significantly greater social reciprocity than the face-to-face group. Significant time effects were noted for heart rate, stress, depression, anxiety, reciprocity, anger expression-out, anger expression-in, anger control-out, and anger control-in. Results also demonstrated that increases in reciprocity and anxiety, and decreases in anger expression-out, were related to increases in heart rate. "In contrast, less anger suppression was a significant predictor of greater systolic blood pressure. However, there were no significant results for group, time, or predictive value for the other psychological, physiological, and lifestyle risk variables. A follow-up study examined the effects of unstructured (n = 13) and highly structured (n =14) internet based programs on physiological, psychological, and lifestyle risk variables for coronary heart disease over 6-months. It also investigated if there were relationships between changes in the psychological and physiological variables over time. Participants stages of change were assessed in relation to psychological and lifestyle risk variables. Results showed that the unstructured group scored significantly higher on anger-expression-out than the highly structured group and that the unstructured groups alcohol usage significantly reduced over time. "The remaining psychological, physiological and lifestyle risk variables did not produce significant group, time, or predictive changes. The stage of change results indicated no significant group or time effects. Results indicated that greater angry reaction scores were predictive of higher heart rate and increased stress scores were predictive of higher diastolic blood pressure. The critical psychological variables predictive of poorer cardiovascular functioning should be targeted in future interventions."; Doctorate of Psychology
