With the exception of large clinical trials, few studies in nursing and other social sciences test interventions. The discipline of nursing needs to maintain a full range of research designs for continued knowledge development. Intervention research presents unique opportunities and challenges for the novice as well as the seasoned researcher. Some of these methodological challenges include the complex nature of human subjects and interventions, including many factors that interfere with the study variables. Preliminary studies often reveal challenges that may not always be predicted or reflected in research texts. These challenges may be as important as the study results for success in future research efforts.
Difficulties encountered in intervention research and suggested strategies for maintaining the integrity of the study are addressed. These challenges include maintaining an adequate sample size, intervention demands, measuring variables, timing issues, and experiencing unexpected events.
Strategies presented include the importance of extensive planning, minimizing subject expectations and rewarding efforts, attention to control group members, incorporating retention strategies, expanding knowledge of variables and the study population, preliminary studies as well as anticipating unexpected events. The need for enhanced communication among nurse researchers, educators and clinicians is addressed. In the current health care arena, nurse researchers must understand organizational dynamics and marketing strategies. Collaborative research efforts can increase the visibility of nursing research as well as funding opportunities.
除大型临床试验外,护理及其他社会科学领域中很少有研究对干预措施进行测试。护理学科需要维持一系列完整的研究设计,以持续推动知识发展。干预研究为新手和经验丰富的研究人员都带来了独特的机遇与挑战。其中一些方法学挑战包括人类受试者和干预措施的复杂性,涉及许多干扰研究变量的因素。初步研究常常揭示出一些在研究文本中未必总能被预测或体现的挑战。这些挑战对于未来研究工作的成功而言,可能与研究结果同样重要。
探讨干预研究中遇到的困难以及为维持研究完整性所建议的策略。这些挑战包括维持足够的样本量、干预要求、测量变量、时间安排问题以及遭遇意外事件。
所提出的策略包括广泛规划的重要性、尽量降低受试者期望并对其努力予以奖励、关注对照组人员、纳入保留策略、拓展对变量及研究人群的认识、开展初步研究以及预料意外事件。文中还探讨了加强护士研究人员、教育工作者和临床医生之间沟通的必要性。在当前的医疗保健领域,护士研究人员必须了解组织动态和营销策略。合作研究工作能够提高护理研究的知名度以及获得资金的机会。
