Do the short version of the Big-Five personality work?
This study mainly aimed to examine the validity and reliability of the short measures of the Big-Five personality. The Big-Five personality is popular among personality researchers. However, the measures that are available have the main disadvantage in that they are long and time-consuming which makes the respondents feel bored and tired and finally not pay attention when filling the measure. Thus, this study tried to test whether the short measures of 5 and 10-items scales can replace the long versions especially for those whose study’s main objective is not on the personality only but the relationships with other constructs in the study.
The overall results show that the 5 and 10-items scales are inferior to the other long versions but they are just a little inferior. The authors suggest that if you do not mainly focus on measuring the Big-Five traits in your study but examining the relationships between the Big-Five traits and other constructs, the 10-times scale is recommended as it can save time for both researchers and participants.
What I like about this study is that it contributed greatly to academia because other researchers can use the proposed scales instead of the long versions. The authors also had rigorous methods for data collection and testing.
