自我决定理论对于理解精神疾病患者接受或不接受精神治疗的原因可能有用。目前的研究以 348 名初步诊断为情绪、焦虑、精神病和人格障碍的荷兰成人门诊患者为样本，检查了基于自我决定理论的三份问卷的心理测量特性——治疗进入问卷 (TEQ)、医疗环境问卷 (HCCQ) 和简短动机反馈表 (SMFL)。结构方程模型表明，TEQ 和 SMFL 的经验因子结构可以由具有三个相互关联因子的模型充分表示。这些被解释为识别的、内化的和外部的动机。荷兰 TEQ、HCCQ 和 SMFL 的可靠性被认为是可以接受的，但可以改进；同类估计值范围为 0.66 至 0.94，具体取决于测量值和患者子样本。对问卷构建有效性的初步支持是以理论上预期与其他量表的关联形式发现的，包括治疗师评价的动机和治疗参与度以及法律规定的治疗。此外，该研究还深入探讨了基于自我决定理论的动机测量、跨理论模型和患有严重精神疾病的精神科门诊患者的治疗动机整合模型之间的关系。
Self-determination theory is potentially useful for understanding reasons why individuals with mental illness do or do not engage in psychiatric treatment. The current study examined the psychometric properties of three questionnaires based on self-determination theory-The Treatment Entry Questionnaire (TEQ), Health Care Climate Questionnaire (HCCQ), and the Short Motivation Feedback List (SMFL)-in a sample of 348 Dutch adult outpatients with primary diagnoses of mood, anxiety, psychotic, and personality disorders. Structural equation modeling showed that the empirical factor structures of the TEQ and SMFL were adequately represented by a model with three intercorrelated factors. These were interpreted as identified, introjected, and external motivation. The reliabilities of the Dutch TEQ, HCCQ, and SMFL were found to be acceptable but can be improved on; congeneric estimates ranged from 0.66 to 0.94 depending on the measure and patient subsample. Preliminary support for the construct validities of the questionnaires was found in the form of theoretically expected associations with other scales, including therapist-rated motivation and treatment engagement and with legally mandated treatment. Additionally, the study provides insights into the relations between measures of motivation based on self-determination theory, the transtheoretical model and the integral model of treatment motivation in psychiatric outpatients with severe mental illness.
