Development of a short form of the Japanese Big-Five Scale, and a test of its reliability and validity

Abstract

Personality scales based on the five-factor model, especially the big-five scale of personality trait adjectives (Wada, 1996), are commonly used in Japan. In this study a short form of the Big-Five Scale was constructed. To avoid changes in the capacity dimension caused by the decrease in the number of items, item selection was conducted after item response theory (IRT) scales were constructed for all the items. In study 1 data was collected from 2099 participants. A generalized partial credit model was applied to the IRT model, and items were selected using the slope and location parameters for each item. Cronbach's alpha showed that the short form, as well as the five sub-scales, had sufficient reliability as a personality test. In study 2, we determined correlations with the NEO-FFI and tested the concurrent validity of the short form. The results indicate that the short form of big-five scale demonstrates sufficient reliability and validity despite the reduced number of items.

Grit and Work Engagement: A Cross-Sectional Study

“…We used a short form of the Japanese Big-Five Scale developed by Namikawa et al . [ 13 ], which comprises 29 items rated on a 5-point scale (1 = not like me at all, 5 = very much like me). Five items are for examining Extraversion (α = .86), 7 items for Conscientiousness (α = .78), 5 items for Neuroticism (α = .82), 6 items for Openness to Experience (α = .76), and 6 items for Agreeableness (α = .78).…”

Big Five Content Representation of the Japanese Version of the Ten-Item Personality Inventory

“…the Big Five personality dimensions (Aronson, Reilly, & Lynn, 2006;Bernard, Walsh, & Mills, 2005;Gosling et al, 2003;Rammstedt & John, 2007;Woods & Hampson, 2005). In Japan, Namikawa et al (2012) tried to reduce the number of items of the Big Five scale, which consists of adjectives, based on the earlier work of Wada (1996). They selected 29 items by using an item response theory (IRT) model and explored the relations between the item-reduced version of the Big Five Scale and the Japanese version of the NEO-FFI (Shimonaka, Nakazato, Gondo, & Takayama, 1999).…”

Development and Validation of the Cognitive Behavioral Therapy Skills Scale Among Japanese College Students

“…Personality: For investigating the correlation between the CBT skills and personality traits, we used the short form of the Big Five Scale of Personality Traits (Big Five Scale), which is well established in reliability and validity, and is frequently used in Japan [25] [26]. The Big Five Scale is rated from 0 = untrue for me to 4 = true for me on each of the ve personality trait factors: Neuroticism, Extraversion, Openness, Conscientiousness, and Agreeableness.…”
