习惯行为、执行意向与青少年身体活动意向与行为:基于计划行为理论的扩展模型     

王丽娟  郑丹蘅 《上海体育学院学报》2020,(2):22-32

在计划行为理论(TPB)的基础上,引入身体活动习惯行为与执行意向,构建扩展TPB(METPB)模型,检验该模型对9~19岁青少年群体的中高强度身体活动(MVPA)的适用性,探讨该模型对小学、初中及高中阶段青少年MVPA影响的差异。结果显示:假设模型的拟合度可以接受,纳入习惯行为与执行意向后,METPB显著地提高了其对身体活动行为的解释力。态度和感知行为控制对MVPA行为意向有显著性影响,解释了31.4%的行为意向方差;行为意向和习惯行为对MVPA行为有显著性影响,解释了18.7%的行为方差;执行意向加强了行为意向朝实际行为的转换。METPB模型对于不同学习阶段青少年MVPA意向及行为的影响有显著性差异。其中:主观规范对小学生与初中生MVPA意向产生了显著性影响,而对高中生的MVPA意向并无显著性影响;感知行为控制对3个阶段学生的MVPA意向产生的影响随着学习阶段的上升不断增强。建议:在对于青少年身体活动的干预中,政府、家庭、学校应重视培养学生对于身体活动参与的正确态度,提高其参与身体活动的意愿,培养其参与身体活动的行为习惯,且在对青少年身体活动干预时考虑学习阶段的差异。  相似文献

Unintended pregnancy as a predictor of child maltreatment     

《Child abuse & neglect》2015

Whereas child maltreatment research has developed considerable evidence on post-natal risk-factors, pre-natal circumstances have been largely overlooked. The circumstances surrounding a pregnancy may considerably impact the environment in which later parenting behaviors occur. This study examines one of the earliest potentially identifiable risk-factors for child maltreatment: the intentions of a pregnancy. Utilizing both mother and father reports, this study focuses on maltreatment risk, as it relates with both parents’ perspectives of the pregnancy's intention. Drawing upon data from the Fragile Families and Child Well Being study, a longitudinal, birth cohort study, survey questions were used that asked parents, at the time of the birth, whether they considered abortion for the child. Unintended pregnancy demonstrates predictive value as one of the earliest identifiable risk-factors for child maltreatment. Regardless of whether the mother or father reported the unintended pregnancy, the relationship with maltreating behavior is largely the same, although for different maltreatment types. Mothers’ reports of unintended pregnancy are associated with psychological aggression, and neglect. Fathers’ reports of unintended pregnancy are associated with physical aggression. Fathers’ perspectives regarding pregnancy intentions matter just as much as mothers,’ and accounting for their perspectives could be important in understanding the maltreating behaviors of both parents. Identifiable in the earliest stages of caregiving, unintended pregnancy may be an important risk-factor in predicting and understanding child maltreatment.  相似文献   

Seeing the forest as well as the trees: general vs. specific predictors of environmental behavior     

Nurit Carmi  Sara Arnon  Nir Orion 《Environmental Education Research》2015,21(7):1011-1028

The domain of environmental protection is comprised from many sub-domains as recycling, conserving water, or reducing the consumption of energy. The attitude–behavior gap is partly explained by the gap between the specificity levels of the particular measured behavior and of its antecedent(s). The present study aimed at assessing the effects of general vs. domain-specific behavior’s proximal antecedents included in the theory of planned behavior (TPB) model (intentions, attitudes towards the behavior, subjective norms, and perceived behavioral control) on performance of specific environmental behaviors (EBs) in five environmental sub-domains. We found that in all of the environmental domains examined, a specifically worded TPB model predicted specific behaviors better than a generally worded TPB model did. However, the magnitude of the improvement varied among behavioral domains and the improvement did not arise from the same TPB elements in every domain. The implications for environmental education and for EB research are discussed.  相似文献

“Crossing the Rubicon”: Understanding Chinese EFL students’ volitional process underlying in-class participation with the theory of planned behaviour     

Davide Girardelli  Vijay K. Patel  Janine Martins-Shannon 《Educational Research and Evaluation》2017,23(3-4):119-137

An extended model based on the theory of planned behaviour (TPB) was used to study Chinese English as a foreign language (EFL) students’ in-class participation. The model included the core TPB constructs (behavioural intentions, attitudes, subjective norms, and perceived behavioural control/self-efficacy) and 2 additional constructs (foreign language classroom anxiety and face-saving) frequently discussed in the literature about Chinese EFL classroom dynamics. A total of 199 Chinese students enrolled in a Sino-American international branch campus were surveyed. The results of a partial least squares (PLS) path modelling analysis revealed that attitudes, subjective norms, perceived behavioural control/self-efficacy, and face-saving explained 46% of the variance in intentions to participate in English in class. Perceived behavioural control/self-efficacy fully mediated the negative indirect effect of foreign language classroom anxiety on intentions. Pedagogical implications and future directions are discussed for implementation purposes.  相似文献
