Self-Determination Theory explores the process through which a person acquires motivation to initiate new behaviours related to health and to maintain them over time. This study aimed to determine the overall fit of Self-Determination Theory Model for Health Behavior to the data obtained from a sample of smokers hospitalized with acute coronary syndrome, and to identify the predictors of smoking status six months after clinical discharge.
The sample included 110 participants, regular smokers, hospitalized due to acute coronary syndrome. Questionnaires were administered to assess autonomous self-regulation, perceived competence, family support, depressive symptoms and meaning in life. Participants were asked if they were currently smokers six months after clinical discharge.
The results showed that the process variables specified by Self-Determination Theory fit the data well. Perceived competence predicted abstinence from smoking six months after clinical discharge.
Our findings have similar characteristics to other international samples in which Self-Determination Theory models havebeen tested. It is important to facilitate perceived competence, as the patients who continue to smoke have shorter length of life.
This study highlights the importance of considering clinical interventions based on Self-Determination Theory to facilitatesmoking cessation.
自我决定理论探讨了一个人获得动力去启动与健康相关的新行为并长期维持这些行为的过程。本研究旨在确定健康行为的自我决定理论模型与从急性冠状动脉综合征住院吸烟者样本中获得的数据的整体拟合度，并确定临床出院六个月后吸烟状况的预测因素。
样本包括110名因急性冠状动脉综合征住院的经常吸烟的参与者。通过问卷调查来评估自主自我调节、感知能力、家庭支持、抑郁症状和生活意义。询问参与者临床出院六个月后是否仍为吸烟者。
结果表明，自我决定理论所指定的过程变量与数据拟合良好。感知能力可预测临床出院六个月后的戒烟情况。
我们的研究结果与其他测试自我决定理论模型的国际样本具有相似特征。促进感知能力很重要，因为继续吸烟的患者寿命较短。
本研究强调了考虑基于自我决定理论的临床干预以促进戒烟的重要性。
