The purpose of this article is to operationalize behaviour change counselling skills (motivation enhancement, behaviour modification, emotion management) that facilitate self-management support activities and evaluate the psychometric properties of an expert rater scale, the Behaviour Change Counselling Scale (BCCS).
Twenty-one healthcare providers with varying levels of behaviour change counselling training interviewed a simulated patient. Videotapes were independently rated by 3 experts on 2 occasions over 6 months. Data on item/subscale characteristics, interrater and test-retest reliability, preliminary data on construct reliability, were reported.
All items of the BCCS performed well with the exception of 3 that were dropped due to infrequent endorsement. Most subscales showed strong psychometric properties. Interrater and test-retest reliability coefficients were uniformly high. Competency scores improved significantly from pre- to posttraining.
Behaviour change counselling skills to guide lifestyle interventions can be operationalized and assessed in a reliable and valid manner.
The BCCS can be used to guide clinical training in lifestyle counselling by operationalizing the component skills and providing feedback on skill achieved. Further research is needed to establish cut scores for competency and scale construct and criterion validity.
本文旨在使促进自我管理支持活动的行为改变咨询技能（动机增强、行为修正、情绪管理）实用化，并评估行为改变咨询量表（BCCS）的专家评分者量表的心理测量特性。
21 名具有不同行为改变咨询培训水平的医疗保健提供者对模拟患者进行了访谈。视频记录由 3 名专家在 6 个月的 2 次独立评估。报告了项目/分量表特征、评分者间信度和重测信度、初步结构信度数据。
BCCS 的所有项目表现良好，除了因不常被认可而被删除的 3 个项目。大多数分量表具有很强的心理测量特性。评分者间信度和重测信度系数均很高。从培训前到培训后，能力得分显著提高。
可以可靠、有效地操作和评估指导生活方式干预的行为改变咨询技能。
BCCS 可以用于通过操作组件技能和提供技能达成的反馈来指导生活方式咨询的临床培训。需要进一步的研究来确定能力和量表结构以及标准有效性的临界分数。
