Development and validation of a questionnaire about the main variables affecting the individual investor's behavior in the Stock Exchange. There is a considerable lack of information about the methodology usually used in most of the studies about individual investor's behavior. The studies reviewed do not show the method used in the selection of the items or the psychometric properties of the questionnaires. Because of the importance of investment in the Stock Exchange nowadays, it seems relevant to obtain a reliable instrument to understand individual investor's behavior in the Stock Exchange. Therefore, the goal of the present work is to validate a questionnaire about the main variables involved in individual investors' behavior in the Stock Exchange. Based on previous studies, we elaborated a questionnaire using the Delphi methodology with a group of experts. The internal consistency (Cronbach alpha=.934) and validity evidence of the questionnaire show that it may be an effective instrument and can be applied with some assurance.
一份关于影响证券交易所个人投资者行为的主要变量的调查问卷的编制与验证。在大多数关于个人投资者行为的研究中，通常使用的方法存在相当大的信息缺失。所审查的研究未展示在项目选择中使用的方法或问卷的心理测量特性。鉴于如今证券交易所投资的重要性，获得一个可靠的工具来理解个人在证券交易所的行为似乎很有意义。因此，本研究的目标是验证一份关于证券交易所个人投资者行为所涉及的主要变量的调查问卷。基于先前的研究，我们采用德尔菲法与一组专家共同编制了一份调查问卷。该问卷的内部一致性（克朗巴哈α系数 = 0.934）和效度证据表明，它可能是一种有效的工具，并且可以有一定把握地应用。
