Confidence in one's ability to perform a given task can be a stronger predictor of performance than skill itself. There are currently no measures to assess confidence with manual wheelchair use. The objective of this study was to develop and assess the content validity of the Wheelchair Use Confidence Scale (WheelCon-M).
A two-phase mixed-methods design was used. Semi-structured interviews were conducted to generate items, followed by a Delphi survey for item selection. Persons who use a wheelchair, health care professionals, and researchers participated in both phases of the study.
An 84-item WheelCon-M was developed based on the qualitative data. After the Delphi survey, a final 62-item WheelCon-M was composed of the following six areas (number of items per area): Negotiating the Physical Environment (33 items), Activities Performed using a Manual Wheelchair (11 items), Knowledge and Problem Solving (6 items), Advocacy (4 items), Managing Social Situations (5 items) and Managing Emotions (3 items).
This article reports the development and content validation of the WheelCon-M. As a scale to measure confidence with wheelchair use was not available prior to this work, clinicians now have a method of identifying individuals who have low confidence with wheelchair use.
对执行给定任务能力的信心可能比技能本身更能有力地预测表现。目前尚无评估使用手动轮椅时信心的方法。本研究的目的是开发并评估轮椅使用信心量表（WheelCon-M）的内容效度。
采用两阶段混合方法设计。进行半结构化访谈以生成条目，随后进行德尔菲调查以选择条目。使用轮椅的人、医疗保健专业人员和研究人员参与了研究的两个阶段。
基于定性数据开发了一个包含84个条目的WheelCon-M。经过德尔菲调查后，最终的WheelCon-M由62个条目组成，分为以下六个领域（每个领域的条目数）：应对物理环境（33个条目）、使用手动轮椅进行的活动（11个条目）、知识与问题解决（6个条目）、自我辩护（4个条目）、应对社交场合（5个条目）和情绪管理（3个条目）。
本文报告了WheelCon-M的开发及内容效度验证情况。由于在本研究之前尚无测量轮椅使用信心的量表，临床医生现在有了一种识别轮椅使用信心较低个体的方法。
