To develop and validate a questionnaire measuring perceived Barriers to Physical Activity in Diabetes (type 1) or BAPAD1. Initially, an open-ended questionnaire was filled by 36 patients. The modal accessible beliefs obtained on this pilot study were analysed and a scale composed of 12 items (BAPAD1) was developed and validated. Seventy-four type 1 diabetic patients filled the BAPAD1 scale. Cronbach alpha coefficient was 0.85 and the correlation between the test-retest scores was 0.84, both indicating adequate reliability of the barriers scale. Each item of BAPAD1 scale displayed very good item characteristic curve except for item 12, which was withdrawn. The test reliability curve indicated that the BAPAD1 scale is informative (value>or=0.82) at all levels of perceived barriers toward physical activity. Moreover, among diabetic-related items, the risk of hypoglycemia showed a particularly good item characteristic curve. In summary, the BAPAD1 scale presents excellent psychometric proprieties and among diabetic-related items, the risk of hypoglycemia should be considered as a significant target to overcome in order to increase physical activity. This new validated tool should be useful in identifying the most salient barriers toward the practice of physical activity and thus, permit more focused intervention in order to overcome those barriers.
开发并验证一份测量1型糖尿病患者身体活动感知障碍的问卷，即BAPAD1。最初，36名患者填写了一份开放式问卷。对该初步研究中获得的主要可及信念进行了分析，并开发并验证了一个由12个项目组成的量表（BAPAD1）。74名1型糖尿病患者填写了BAPAD1量表。克朗巴哈α系数为0.85，重测分数之间的相关性为0.84，这两者均表明障碍量表具有足够的信度。BAPAD1量表的每个项目除第12项外均显示出非常好的项目特征曲线，第12项已被删除。测试信度曲线表明，BAPAD1量表在身体活动感知障碍的所有水平上均具有信息性（值≥0.82）。此外，在糖尿病相关项目中，低血糖风险显示出特别好的项目特征曲线。总之，BAPAD1量表具有出色的心理测量学特性，在糖尿病相关项目中，低血糖风险应被视为增加身体活动需要克服的一个重要目标。这个新的经过验证的工具应有助于识别身体活动实践中最突出的障碍，从而允许进行更有针对性的干预以克服这些障碍。
