Initial psychometric properties of Acceptance and Action Questionnaire - II - Brazilian version

Psychological flexibility (PF) model has extensive evidence in several countries but its research in Brazil is limited due to lack of suitable instruments. This study gathers psychometric evidence from an FP instrument, Acceptance and Action Questionnaire-II, adapted for Brazil. After translated and adapted, 1,352 college students filled it, and same subsamples also filled scales on resilience, general health, depression and anxiety. Results indicated unidimensional structure and satisfactory reliability. FP in males was superior to females and increased with aging. There was also a positive correlation with resiliency and overall health, and a negative one with depression and anxiety. Psychometric properties were satisfactory, but ought to be evaluated in diverse samples. The instrument seems suitable for use both in studying behavior change and mechanisms of therapeutic change.

心理灵活性（Psychological Flexibility, PF）模型在多个国家均已获得大量实证支持，但在巴西的相关研究因缺乏适配的测评工具而进展有限。本研究针对适配巴西人群的接纳与行动问卷第二版（Acceptance and Action Questionnaire-II, AAQ-II）这一PF测评工具，收集其心理测量学证据。经翻译与文化适配后，共有1352名大学生完成了该问卷；同时部分子样本还完成了针对心理韧性（Resilience）、总体健康（General Health）、抑郁（Depression）及焦虑（Anxiety）的量表测评。结果表明，该问卷具备单维结构与良好的信度。男性的心理灵活性水平显著高于女性，且随年龄增长而提升。此外，心理灵活性与心理韧性及总体健康呈正相关，与抑郁、焦虑呈负相关。本研究所得的心理测量学属性表现良好，但仍需在多样化样本中进一步验证。该测评工具或可适用于行为改变及治疗性改变机制的相关研究。
