Patient behaviors performed in the self-management of asthma have been investigated by use of black box theory as a model for examining behavioral change. Consequently, the context within which patients learn and perform processes of self-management has been ignored. The purpose of the present study was to investigate contextual and behavioral elements that comprise the management of asthma attacks by a large number of adult patients. A total of 3442 reports of attack were obtained from 90 subjects, including 76 patients described in the article by Kotses and colleagues, 9 who dropped out of the study, and 5 who served as pilot subjects. The major focus of the analysis, however, was on the 63 subjects who submitted forms during two periods: intake/baseline and training/after training. Data included information about the episode (e.g., severity, duration, etc.), prior actions taken by patients (e.g., adherence to treatment regimens, collection of peak flow data, etc.), and the impact of contextual variables (e.g., setting where attack occurred, time when attack occurred, etc.) on patient behaviors The variables were subjected to a probability analysis to demonstrate changes in the probability of responses as influenced by contextual variables present during any given attack. The results indicated that contextual variables affect behavioral change. Changes occurred in actions taken to manage an attack in the two periods, intake/baseline and during and after training. Three findings are of interest. The first was the emergence of discriminative stimuli that because they were present when self-management skills were initially reinforced, altered the future probability of performance of the skills. Peak flow values and asthma action plans qualified as discriminative stimuli in that their use often prompted patients to perform steps to alleviate and abort episodes. Second, several processes comprise self-management, ranging from goal setting to self-appraisal of one's actions. Self-monitoring is the backbone of self-management. However, what emerged from the current study is the importance of two other processes: 1) information collection and processing and 2) decision making. When subjects were introduced to self-monitoring via use of peak flow meters, an asthma diary, and a report of an attack, they began using these tools, often in a trial-and-error manner, to match the information they obtained to the actions they took. As a result, they became skilled at self-monitoring prior to training. During and after training, however, patients indicated they were skilled at processing and making decisions based on the data they collected. Finally, stimuli present during an attack came to prompt distinctive patterns whereby individual patients considered the reciprocal interaction of environmental, physiological, behavioral, and cognitive variables to control attacks. Action taken by patients reflected data processing and decision making on the part of patients in selecting and performing those self-management skills they anticipated would generate the best outcomes.
以黑箱理论作为考察行为改变的模型,对哮喘自我管理中患者的行为进行了研究。然而,患者学习和执行自我管理过程的背景却被忽视了。本研究的目的是调查大量成年患者哮喘发作管理中的背景因素和行为因素。从90名受试者那里共获得了3442份发作报告,其中包括Kotses及其同事文章中描述的76名患者、9名退出研究的患者以及5名作为试点受试者的患者。然而,分析的主要重点是在两个阶段提交表格的63名受试者:入院/基线期和训练期/训练后。数据包括有关发作的信息(如严重程度、持续时间等)、患者之前采取的行动(如坚持治疗方案、收集峰流速数据等)以及背景变量(如发作发生的环境、发作发生的时间等)对患者行为的影响。对这些变量进行概率分析,以证明在任何给定发作期间存在的背景变量所影响的反应概率的变化。结果表明,背景变量会影响行为改变。在入院/基线期以及训练期间和训练后,管理发作所采取的行动发生了变化。有三个发现值得关注。第一个是辨别性刺激的出现,由于它们在自我管理技能最初得到强化时出现,改变了这些技能未来执行的概率。峰流速值和哮喘行动计划符合辨别性刺激的条件,因为它们的使用常常促使患者采取措施缓解和终止发作。其次,自我管理包括几个过程,从目标设定到对自己行为的自我评估。自我监测是自我管理的核心。然而,当前研究中出现的另外两个过程的重要性在于:1)信息收集和处理以及2)决策。当受试者通过使用峰流速仪、哮喘日记和发作报告被引入自我监测时,他们开始使用这些工具,通常是以试错的方式,将获得的信息与他们采取的行动相匹配。结果,他们在训练前就熟练掌握了自我监测。然而,在训练期间和训练后,患者表示他们擅长根据收集到的数据进行处理和决策。最后发作期间出现的刺激促使形成了独特的模式,即个体患者考虑环境、生理、行为和认知变量之间的相互作用来控制发作。患者采取的行动反映了患者在选择和执行他们预期会产生最佳结果的那些自我管理技能时的数据处理和决策。
