Changes in hope and health-related quality of life in couples following acute myocardial
infarction: a quantitative longitudinal study
Sammanfattning
Background: Acute myocardial infarction (AMI) is a life-changing event that affects both the patient and the family and can have an influence on hope as well as HRQoL during the recovery period.
Aims: To compare self-rated scores of hope and health-related quality of life (HRQoL) 1, 7, 13 and 25 months, after an AMI with regard to (i) differences across time, and (ii) differences between patients and their partners.
Design: Explorative and longitudinal study.
Methods: In this nonrandomized study, Short Form 36 Health Questionnaire (SF-36) and Herth Hope Index-Swedish (HHI-S) questionnaires were completed by thirteen post-AMI patients and their partners. Data were collected on four occasions.
Results: In general, hope as well as HRQoL scores increased over time. A 2 (groups) × 4 (times) anova for mixed design showed significant changes in mental as well as in physical health over time but no significant effect of group on mental or physical health. Calculation of the minimum detectable change (MDC-index) for HHI-S and SF-36 revealed that scores between data collection points were not stable.
Conclusion: Our results show that although hope and HRQoL scores increased, only a few of the changes were statistically significant. Neither HHI-S nor SF-36 seems to measure stable states. Changes in hope and HRQoL levels may be due to participants striving to adapt to the current situation.
Relevance to clinical practice: These results can be used in the training of nursing staff to enhance their understanding of the significance of a family-centred approach after an AMI. Published by arrangement with John Wiley & Sons.
