计划行为理论及其扩展模型对发送性短信行为的预测

Prediction of Sexting: Based on the Theory of Planned Behavior and Its Extended Model

目的:探究计划行为理论及其扩展模型能否预测中国青年的发送性短信行为。方法:基于计划行为理论与原型意愿模型的理论框架,对348名年龄在18到25周岁之间的青年进行问卷调查,建立结构方程模型,检验模型拟合情况并分析各变量间的路径关系。结果:计划行为理论模型与其扩展模型均拟合良好,态度、主观规范与知觉行为控制预测了发送性短信行为意向,同时态度与描述性规范、原型认知预测了发送性短信行为意愿,而行为意向直接影响了发送性短信行为。结论:计划行为理论及其扩展模型可以预测中国青年的发送性短信行为。

Objective: To explore whether the theory of planned behavior (TPB) and its extended model can predict sexting among Chinese young adults. Methods: Based on the theoretical framework of the TPB and the prototype willingness model (PWM), a questionnaire survey was conducted on 348 young adults aged between 18 and 25 years old. Two structural equation models were established respectively to test the fit of models and analyze the path relationships among the variables. Results: Both the TPB model and its extended model fit reasonable. Attitude, subjective norms, and perceived behavioral control predicted intention to sexting, while attitude and descriptive norms, and prototype perception predicted willingness to sexting, and intention to sexting directly affected sexting behavior. Conclusion: The TPB model and its extended model can predict sexting among Chinese young adults.
