Based on self-determination theory, this study tests a model positing that perceived autonomy support from parents and health care providers positively predicts self-efficacy and autonomous self-regulation in dietary self-care. In turn, self-efficacy and autonomous self-regulation predict better dietary self-care over time.
Longitudinal data were collected in a consecutive series of 289 adolescent patients with type I diabetes at two time points separated by a two-year interval.
Structural equation modeling analysis revealed that perceived autonomy support from health care providers at Time 1 (T1) positively predicted self-efficacy and autonomous self-regulation at Time 2 (T2), T1 self-efficacy and autonomous self-regulation positively predicted T2 dietary self-care, and T1 dietary self-care positively predicted T2 autonomous self-regulation.
Autonomy support from health care providers appears to help adolescents develop motivational factors for dietary self-care and adhere to dietary recommendations.
本研究基于自我决定理论，验证了一个模型，即父母和医疗保健提供者感知到的自主性支持正向预测饮食自我护理中的自我效能感和自主自我调节。反过来，自我效能感和自主自我调节又预测了随着时间的推移饮食自我护理的改善。
在连续两个两年的时间间隔内，在 289 名患有 1 型糖尿病的青少年患者中连续收集了纵向数据。
结构方程模型分析表明，医疗保健提供者在 T1 时感知到的自主性支持正向预测 T2 时的自我效能感和自主自我调节，T1 时的自我效能感和自主自我调节正向预测 T2 时的饮食自我护理，而 T1 时的饮食自我护理又正向预测了 T2 时的自主自我调节。
医疗保健提供者的自主性支持似乎有助于青少年发展饮食自我护理的动机因素，并坚持饮食建议。
