Abstract

OBJECTIVES

The present research tested: (a) whether prototype perceptions and descriptive norms from the prototype/willingness model (PWM; Gibbons, Gerrard, Blanton, & Russell, 1998) enhance the prediction of adolescents' intentions to engage in health-protective and health-risk behaviours after variables from the theory of planned behaviour (TPB; Ajzen, 1991) and past behaviour have been taken into account and (b) whether images of the type of person who engages in a health behaviour (actor prototypes) and images of the type of person who does not engage in a health behaviour (abstainer prototypes) have equivalent predictive validity.

DESIGN

An experimental design with a single between participants factor (actor versus abstainer prototype) was employed.

METHOD

Participants in this study were 247 school pupils who completed measures of TPB variables, PWM variables and past behaviour in relation to three health-protective and three health-risk behaviours.

RESULTS

Findings indicated that PWM variables accounted for a significant proportion of the variance in behavioural intentions after TPB variables and past behaviour had been taken into account (Mean deltaR2=.05). Perceived similarity to prototypes was the most consistent additional predictor of intention. Actor and abstainer prototypes exhibited equivalent predictive validity.

CONCLUSIONS

The present research suggests that variables from the PWM, especially prototype similarity, enhance the predictive validity of the TPB. The findings also provide new evidence that acquiring the characteristics of both health and risk images may be goals among adolescents and suggest that both healthy and risky prototypes constitute useful cognitive targets for interventions.

摘要

目的

本研究检验了:(a) 在考虑了计划行为理论(TPB;阿杰恩,1991)中的变量和过去行为之后,原型/意愿模型(PWM;吉本斯、杰勒德、布兰顿和拉塞尔,1998)中的原型认知和描述性规范是否能增强对青少年参与健康保护行为和健康风险行为意图的预测;以及(b) 参与健康行为的人的类型的图像(行为者原型)和不参与健康行为的人的类型的图像(节制者原型)是否具有同等的预测效度。

设计

采用了一种单因素组间设计(行为者与节制者原型)的实验设计。

方法

本研究的参与者为247名在校学生,他们完成了与三种健康保护行为和三种健康风险行为相关的TPB变量、PWM变量和过去行为的测量。

结果

研究结果表明,在考虑了TPB变量和过去行为之后,PWM变量在行为意图的方差中占了很大比例(平均ΔR2 = 0.05)。与原型的感知相似性是意图最一致的额外预测因素。行为者原型和节制者原型表现出同等的预测效度。

结论

本研究表明,PWM中的变量,尤其是原型相似性,增强了TPB的预测效度。研究结果还提供了新的证据,表明获得健康和风险形象的特征可能是青少年的目标,并表明健康和有风险的原型都是干预的有用认知目标。
