背　景:成人氣喘罹患人數及死亡率較兒童高，發病率及再住院率亦有增加趨勢，文獻指出提昇氣喘病患自我照顧行為及自我效能，可以降低氣喘病患發病率及再住院率，因此自我照顧行為及自我效能為氣喘病患重要的照護議題。目　的:本研究目的為探討自我效能介入方案(1)對成人氣喘病患自我照顧行為之影響；(2)對成人氣喘病患自我效能之影響。方　法:本研究採兩組前後測之實驗設計法，2009年3月2日至2010年1月31日於高雄市某醫學中心胸腔內科門診60位氣喘病患，隨機分為實驗組及控制組各30人。實驗組接受自我效能介入方案，包括觀看15－20分鐘的DVD影帶、提供成人氣喘自我效能衛教手冊、病友團體經驗分享、參與電話訪談；控制組接受傳統的門診衛教方案。研究工具為成人氣喘病患自我照顧行為量表(CVI .95，Cronbach’s α值為 .82），及成人氣喘病患自我效能量表（CVI .98，Cronbach’s α值為 .82）。結　果:結果顯示(1)自我效能方案對成人氣喘病患所有自我照顧行為，包括遵從服藥（p =.008）、自我監控（p = .000）、遠離過敏原（p = .001）、定期返診（p = .000）及規律的運動（p = .016）均有顯著性進步；.自我效能方案對成人氣喘病患的預防氣喘發作（p = .030）及氣喘發作時的處理（p = .017）自我效能均有顯著性進步。結　論:依本研究之自我效能方案可作為成人氣喘自我照顧臨床實務之參考。

Background: The prevalence of asthma and associated mortality is higher among adults than among children, as are associated morbidity and hospital readmission rates. The literature shows that promoting patient self-care behaviors and selfefficacy helps reduce recurrence and hospital readmission rates.Therefore, self-care behaviors and self-efficacy represent critical issues in successful asthma management.Purpose: This study was developed to investigate the effects of a self-efficacy intervention on (a) the self-care behaviors of adult asthma patients and (b) the self-efficacy of adult asthmatic patients. The study used a pretestYposttest experimental design.
Methods: A total of 60 asthma outpatients who visited the chest medicine division of a medical center in Kaohsiung City between March 2, 2009, and January 31, 2010, were assessed. Patients were randomly divided into two groups(experimental and control), with 30 patients assigned to
each. Experimental group participants received the selfefficacy
intervention program, which included watching a 15- to 20-minute DVD, received a healthcare booklet on selfefficacy for adult asthmatic patients, were asked to share their illness experience with support groups, and received medical follow-ups by telephone. Control group patients received conventional health education administered by the
outpatient department. Study instruments included a selfcare
behavior scale for adult asthmatic patients (content validity index = .95, Cronbach’s ! = .82) and a self-efficacy scale for adult asthmatic patients (content validity index = .98,Cronbach’s ! = .82).
Results:The two key findings of this study were as follows:(a) There was a significant improvement in the self-care behaviors of patients who received self-efficacy intervention in terms of medication adherence (p = .008), self-monitoring (p = .000), avoidance of antigens (p = .001), regular follow-up visits (p = .000), and regular exercise (p = .016); and (b) the program improved participant self-efficacy in terms of both asthma
attack prevention (p = .030) and management during asthma attacks (p= .017).
Conclusions:On the basis of these results, self-efficacy intervention
has been demonstrated a beneficial addition to adult asthmatic patient self-care regimens.
