|Objective: To examine self-efficacy among adults with asthma, following a nurse led educational intervention using biofeedback of treatment use.
Method: Participants (n=88) who had completed a larger RCT (INCA Sun) took part in this study. Participants were randomised into a control (best practice education) or intervention (best practice education, enhanced with personalised biofeedback) group in the RCT. Biofeedback on inhaler treatment use was generated using inhaler adherence technology, attempted and actual adherence was recorded. An adapted version of the Asthma Self-Efficacy Questionnaire was completed by all participants once.
Results: Both study groups had highest mean attempted and actual adherence in month 1 and lowest in month 8. Control group felt most confident in communicating with their healthcare provider, intervention group felt most confident about the use of their inhalers. The highest mean level of overall self-efficacy was reported by the control group; despite this they showed a statistically significant (p=0.003) decline in mean actual adherence between month 1 and month 8.
Conclusion: A high level of perceived self-efficacy did not reflect actual behaviour when compared to objective measures of self-management such as inhaler adherence. Biofeedback when incorporated into asthma self-management strategies results in a more accurate assessment of self-efficacy, representative of actual behaviour. This information can be used to deliver personalised asthma and self-management education, ensuring effective asthma management.
