Objective: To evaluate an intervention programme based on the Health Action Process Approach and designed to increase the intake of fruit and vegetables (F&V) among Iranian adolescents aged 13 to 18.
Design: A randomised controlled trial with three arms examined the short- (1 month) and long-term (6 months) effects of the intervention. There were two intervention groups (one included adolescents only [A group; n = 510]; the second included mothers and adolescents [M + A group; n = 462]) and a control group (n = 483). All participants were recruited from schools.
Main outcome measures: Social cognitions, self-regulatory processes and F&V intake.
Results: The intervention led to an increase in F&V intake for adolescents in the short and long terms. Adolescents in the M + A group increased their F& V intake more than adolescents in the A group. Outcome expectancies, self-monitoring, intentions, action and coping planning, perceived social support and behavioural automaticity mediated the effect of the intervention on F&V intake.
Conclusion: The theory-based intervention led to an increase in F&V intake and promoted more positive social cognitions and self-regulatory processes among Iranian adolescents. The findings also provide evidence that involving mothers in an intervention can confer additional benefit. 相似文献
This paper seeks to reflect in a narrative way on the pedagogical processes involved in teaching pastoral theology at United Theological College, Sydney. The paper recognizes that the process of learning pastoral theology is a significant part of the content learned in pastoral theology. The learning process in pastoral theology also contributes to (trans)formational learning in those being formed for ministry. The paper seeks to contribute to the community of pastoral theologians by reflecting on the experience of teaching within a particular school. 相似文献
Culture can be thought of a set of shared practices, beliefs, and values that are transmitted across generations through language [Bruner, J. (1990). Acts of meaning. Cambridge, MA: Harvard University Press]. Teaching is one way that culture is transmitted, but forms of teaching vary across cultures and across activity settings within cultures. This article explores the impact of culture on styles of teaching in a place where more than one cultural model of teaching is found: the Zinacantec Maya of Chiapas, Mexico. Zinacantecs have an indigenous model of teaching that applies to the learning of informal tasks, such as making tortillas and weaving. When children go to school, the indigenous model interacts with the model found at school, and this mixed model is transferred back home to sibling interactions. Videotaped ethnographic observations and quantitative discourse analyses reveal cultural patterns in the development of children's teaching. 相似文献
