Risk Attitude Scale风险态度量表(Weber等,2002)
简介
风险态度(Risk Attitude)是指一种描述性的标签,用于推定作为一个人选择的基础的效用函数的形状。一个人的风险态度描述了他或她的效用函数的形状。个体对风险的态度存在区别,已有研究对于个体在风险态度方面的测量有所缺陷。Weber等(2002)提供了一种新的风险态度量表,能够让研究人员和实践中的从业者在六个常见的内容领域中评估传统风险态度(conventional risk attitudes)和感知风险态度(perceived-risk attitudes)。
对于许多应用来说,如果风险态度只是为了预测目的而被测量,风险承担的个人或领域差异的原因是无关紧要的。在这些情况下,附录C中提供的“风险行为”工具的一个或多个子量表就足够了。然而,如果衡量风险态度的目的是影响观察到的行为(即说服个人或团体做出更多的风险厌恶或更多的风险寻求选择),风险承担差异的原因就变得很重要。在这种情况下,需要评估传统的风险态度(来自风险行为量表)和感知风险态度(通过回归风险和行为得分对感知风险和收益的影响;参见附录D中的规模说明),以查明是否观察和期望行为之间的差异是(可能不现实的)对风险或利益的看法或对感知风险的(可能不合适的)态度的结果。
信度与效度
总共进行了三个研究。研究1描述了Weber等(2002)风险态度量表alpha版本的构建,其中包括五个内容领域:金融(Financial),健康/安全(Health/safety),伦理(Ethics),娱乐(Recreational),社会(Social),10个项目子量表;研究2记录了该量表的区分和聚合效度(discriminant and convergent validity)以及重测信度(test–retest reliability)。 根据研究1和2的结果,研究3提供了量表的beta版本,其中8个项目分为四个内容领域:健康/安全,伦理,社会和娱乐风险,和两个4项目子量表,将金融风险分为投资和赌博两个组成部分。
总共有121名参与者参加了研究1,参与者填写了研究1中开发的50项风险行为和风险感知量表(the 50-item Risk-Behavior and Risk-Perception scales)。他们还评估了他们期望从每个风险行为中获得的好处。为了验证受访者在风险行为量表上报告的行为意图,研究者使用从1(“从不”)到3(“多次”)的三分评级量表,收集了受访者过去五个内容领域中常见风险行为频率的自我报告。此外,研究者观察了受访者在实验室“赌场”环境中进行的一系列五大风险货币决策,并填答问卷调查表。
研究者对于在一个月的间隔内完成风险行为量表的参与者,进行了两次测试,以测量量表的重测信度。重测信度与风险感知量表是相似的,金融和社会分量表的信度值较低(分别为0.42和0.47),但健康、伦理和娱乐分量表的信度值较高(分别为0.66,0.67和0.56)。在效度方面,平均相关系数为0.49。
