Abstract

Background

The MacArthur Competence Assessment Tool for Treatment (MacCAT-T), a semi-structured interview, is designed to evaluate patient decision-making capacity, a crucial aspect of patient-physician interaction.

Methods

A process study was undertaken of a sample of Mexicans diagnosed with schizophrenia aged between 18 and 50 years to determine the validity and reliability of the MacCAT-T in this population. A ROC curve was plotted to obtain discriminant validity, convergent validity was tested with the VAGUS scale and internal consistency was obtained as a measure of reliability.

Results

Adequate sensitivity (0.95) and specificity (0.75) were obtained with a cut-off point of seven. Significant correlations were observed between the MacCAT-T and the VAGUS scales (r = 0.54 and r = 0.76, p < 0.05), indicative of adequate convergent validity. Internal consistency values were 0.93 for the total score and over 0.80 for all its dimensions.

Conclusion

This study demonstrated that the MacCAT-T is a valid, reliable tool that can be used to assess decision-making capacity in Mexican patients with schizophrenia, which could have a heuristic value for promoting ethical clinical and research practices designed to achieve the crucial balance between patient autonomy and safeguarding.

墨西哥版麦克阿瑟治疗决策能力评估工具（MacCAT-T）在精神分裂症患者中的效度和信度

麦克阿瑟治疗能力评估工具（MacCAT-T）是一种半结构化访谈，旨在评估患者的决策能力，这是医患互动的一个重要方面。方法对年龄在18岁至50岁之间的墨西哥精神分裂症患者进行了一项过程研究，以确定MacCAT-T在该人群中的有效性和可靠性。绘制ROC曲线获得判别效度，用VAGUS量表检验收敛效度，获得内部一致性作为信度的度量。结果灵敏度为0.95，特异度为0.75，分界点为7。MacCAT-T和VAGUS量表之间存在显著相关性（r = 0.54和r = 0.76, p < 0.05），表明具有足够的收敛效度。总分的内部一致性值为0.93，所有维度的内部一致性值均超过0.80。结论本研究表明，MacCAT-T是一种有效、可靠的工具，可用于评估墨西哥精神分裂症患者的决策能力，这对于促进临床和研究实践的道德规范具有启发式价值，旨在实现患者自主和保护之间的关键平衡。

期刊介绍： The International Journal of Law and Psychiatry is intended to provide a multi-disciplinary forum for the exchange of ideas and information among professionals concerned with the interface of law and psychiatry. There is a growing awareness of the need for exploring the fundamental goals of both the legal and psychiatric systems and the social implications of their interaction. The journal seeks to enhance understanding and cooperation in the field through the varied approaches represented, not only by law and psychiatry, but also by the social sciences and related disciplines.
