This article investigates the psychological distance and its effects on a psychological scales with different numbers of response options, i.e. 4-, 5-, and 7-point scales. Rather than using simulation studies that manipulate the number of categories, It has made use of real data from around 700 undergraduate students’ responses on some personality sub-scales and reported descriptive statistics, reliability measure (Cronbach’s alpha), and Wakita’s (2004) methods measures, and authors’ suggested measures of adjusted scale values to examine the effects. They adopted such a conversion technique: the scale scores of the 4-point scale and 7-point scale were adjusted to the same range as the 5-point scale. By comparing between the conventional scale scores and the converted scale scores, the authors suggested that for 7-point scale, there is a tendency for participants to avoid the end categories, which in turn might imply that and increase in the number of options biases respondents against answers containing the strongest expressions. What is emphasized is that the effects of different numbers of category options do not appear on the descriptive statistics and reliability measures. The authors argued the suggested method would help determine and equalize the psychological distance between the category options when Likert scale is used. However, generalization of the findings of this article and its practicality have yet to be established by replication of the study in measurements via items other than personality scale and persons other than undergraduate students.
