This report presents reliability, validity and sensitivity indices for the Motivational Interviewing Treatment Integrity (MITI) scale. Factor analysis of MI treatment sessions coded with the Motivational Interviewing Skills Code (MISC) was used to derive 10 elements of MI practice, forming the MITI. Canonical correlation revealed that the MITI captured 59% of the variability in the MISC. Reliability estimates for the MITI were derived using three masked, independent coders. Intra-class coefficients ranged from .5 to .9 and were generally in the good to excellent range. Comparison of MITI scores before and after MI workshops indicate good sensitivity for detecting improvement in clinical practice as result of training. Implications for the use of this instrument in research and supervision are discussed.
本报告展示了动机性访谈治疗完整性（MITI）量表的信度、效度和敏感度指标。对采用动机性访谈技能编码（MISC）进行编码的动机性访谈治疗环节进行因素分析，以得出动机性访谈实践的10个要素，构成了MITI。典型相关分析表明，MITI涵盖了MISC中59%的变异性。MITI的信度估计值是通过三位不知情的独立编码员得出的。组内系数范围为0.5至0.9，总体处于良好到优秀的范围。动机性访谈工作坊前后MITI分数的比较表明，该量表在检测培训对临床实践的改善方面具有良好的敏感度。文中还讨论了该工具在研究和督导中的应用意义。
