Adaptation and validation of the Measuring of Treatment Adherence for mental health

ABSTRACT Objective: to adapt culturally and validate the Measuring Instrument of Treatment Adherence for mental health. Method: methodological study, carried out with 300 individuals with mental disorders, in two Psychosocial Care Centers in Curitiba, state of Paraná, Brazil, from April to June 2014. The cross-cultural adaptation was developed according to international recommendations, the construct validation was made by exploratory factor analysis, and internal consistency was verified by Cronbach’s alpha. Results: through the evaluation of a committee of experts and completion of the pre-testing, face and content validation was achieved. From the factor analysis, we identified two factors of the instrument’s construct: involuntary action and voluntary action, with a total explanation variance of 55.7%. The value of Bartlett’s test of sphericity was p<0.001. Cronbach’s alpha was 0.74. Conclusion: the adapted and validated instrument proved to be trustworthy to be applied to the verification of adherence to drug therapy for individuals with mental disorders.

摘要
目的：对心理健康治疗依从性测量工具进行跨文化调适与效度验证。
方法：本研究为方法学研究，于2014年4月至6月在巴西巴拉那州库里提巴市的2家精神卫生社会心理照护中心（Psychosocial Care Centers）开展，共纳入300名精神障碍患者。研究按照国际指南完成跨文化调适（cross-cultural adaptation），采用探索性因子分析（exploratory factor analysis）进行结构效度验证，并通过克朗巴哈α系数（Cronbach’s alpha）检验内部一致性。
结果：通过专家委员会评估与预试验，本工具完成了表面效度与内容效度验证。因子分析结果显示，该工具的结构包含两个维度：不自主依从行为与自主依从行为，总解释方差为55.7%。巴特利特球形检验（Bartlett’s test of sphericity）结果为p<0.001，克朗巴哈α系数为0.74。
结论：经调适与效度验证后的该工具，可可靠用于评估精神障碍患者的药物治疗依从性。
