ABSTRACT

We propose and test several hypotheses derived from the expanded theory of normative social behavior (TNSB) that also includes collective norms (with descriptive and injunctive norms). Data come from a quasi-experiment intervention to promote safer driving among adolescents in Serbia. The intervention was administered among high school students, most of whom were on the verge of receiving their driver’s licenses. Longitudinal data were collected from treatment and control schools at baseline (N = 1,449) and four months later at end line (N = 1,072). Descriptive norms at baseline predicted six-month changes in safer-driving intentions among women (β = .010 p < .05) but not among men. Main-effects of injunctive and collective norms were not significant. However, a significant interaction between descriptive norms and collective norms emerged among men (though not among women) and injunctive norms interacted with both collective norms and descriptive norms among women (but not among men). Initial evidence adds credence to the idea of enhancing the TNSB by adding both injunctive and collective (together with descriptive) norms as drivers of behaviors.

摘要

我们提出并检验了源自规范社会行为（TNSB）扩展理论的几个假设，该理论还包括集体规范（具有描述性和禁令性规范）。数据来自一项旨在促进塞尔维亚青少年安全驾驶的准实验干预措施。干预是在高中生中进行的，他们中的大多数人即将获得驾驶执照。从基线（ N = 1,449）和四个月后的终点线（N = 1,072）收集治疗和对照学校的纵向数据。基线的描述性规范预测了女性安全驾驶意图的六个月变化（β = .010 p< .05) 但男性中没有。禁令和集体规范的主要影响不显着。然而，描述性规范和集体规范之间的显着相互作用出现在男性中（尽管不是在女性中），禁令性规范与集体规范和描述性规范在女性中（但不是在男性中）相互作用。最初的证据增加了通过添加禁令和集体（连同描述性）规范作为行为驱动因素来增强 TNSB 的想法的可信度。
