The BFI-10

The BFI-10 is a 10-item scale measuring the Big Five personality traits Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness. The scale was developed based on the 44-item Big Five Inventory (BFI-44; John, Donahue, & Kentle, 1991; Rammstedt, 1997) and designed for contexts in which respondents’ time is severely limited. Test-retest correlations suggest acceptable reliability. Correlations with other Big Five instruments, correlations between self and peer ratings, and associations with sociodemographic variables suggest good validities of the BFI-10 scores.

Can I use the BFI-10 in my own research?

The BFI-10 is an open-access instrument that can be used for non-commercial research. There is no need to ask for permission. If you use the BFI-10, please cite

In which contexts can I use the BFI-10?

The BFI-10 is particularly designed for large-scale assessments with limited time resources. The BFI-10 should not be used for individual diagnostics because the reliability of the instrument does not allow to make inferences about single respondents. The BFI-10 must not be used for commercial purposes. If you use the BFI-10, please consider supporting Open Science by publishing your data in a data repository such as the GESIS datorium.

How was the BFI-10 developed?

The BFI-10 was simultaneously developed in English and German (see Rammstedt & John, 2007). Items were selected that they (1) measure core, but not redundant aspects of the Big Five factors, (2) show simple-structure of factor loadings, (3) represent each factor with one positively and one negatively keyed items, and (4) have identical meaning in English and German.

How well do the BFI-10 scales represent the scales of the BFI-44?

In both US and German samples, the Fisher-Z-corrected overall mean correlation between the dimensions of the BFI-10 and those of the BFI-44 were r=.83 (Rammstedt & John, 2007) which means that the BFI-10 items predicted almost 70% of the variance of the BFI-44 scales.

Is the BFI-10 reliable?

Several studies demonstrate acceptable reliability estimates for the BFI-10. In a sample of American students, Rammstedt and John (2007) demonstrated test-retest correlations between r=.65 (Openness) and r=.79 (Extraversion) over a period of 6 to 8 weeks. Comparable results were found for the German BFI-10 items in several studies. For example, Rammstedt et al. (2014) reported retest correlations between r =.49 (Neuroticism) and =.62 (Openness) over a period of 6 weeks.

The items' internal consistencies are considerably smaller than the test-retest correlations. However, the internal consistency underestimates the reliability for heterogeneous scales such as the BFI-10 were the items aim to measure distinct aspects of the construct.

Is the BFI-10 valid?

There are several findings that support the factorial validity, the construct validity, and the criterion validity of the BFI-10.

Factorial validity: The correlations among the Big Five scales are low, ranging from r=.08 to r=.13 in all US and German samples (Rammstedt & John, 2007). Furthermore, factor analyses reveal a simple-structure of the items with substantial loadings on the convergent factor (averaged .64) and negligible secondary loadings on the four other factors (averaged .08) (Rammstedt & John, 2007; Rammstedt et al., 2013; Rammstedt et al., 2014).

Construct validity: Correlations with the NEO-PI-R domain and facets scales show substantial convergent and discriminant validity. The pattern of correlations for the BFI-10 is generally similar to that for the BFI-44 (Rammstedt & John, 2007).

Criterion validity: Rammstedt & John, 2007 report averaged correlation between self reports and peer reports of r=.44. Further studies reveal associations with sociodemographic variables, subjective well-being, deviance, social network, effort-reward-imbalance, or political participation (Rammstedt et al., 2013; Rammstedt et al., 2014).

Are there reference statistics for the BFI-10?

Yes, there are reference statistics based on a representative sample of the general population in Germany (Rammstedt et al., 2014). Furthermore, the data of the ISSP 2005 can be used as reference statistics for Israel, Belgium, the Czech Republic, Denmark, the Netherlands, the UK, France, Switzerland, Japan, Korea, Latvia, the Philippines, Russia, the Dominican Republic, Mexico, and Taiwan (please note that the quality of most translations have not been tested yet and thus, data should be interpreted with caution).

Do I have to control for acquiescence?

Samples that are heterogeneous in education, cognitive ability, or age can cause problems such as acquiescence responding which in turn can bias correlations, factor loadings, or correlation with external criteria (Danner, Aichholzer, & Rammstedt, 2015).

If scale scores of the Big Five (extraversion, agreeableness, conscientiousness, neuroticism, and openness) are analyzed, the BFI-10 is already adjusted for acquiescence because the scales are balanced (consisting of one positively keyed and one negatively keyed item).

However, if items scores are analyzed, it may be necessary to adjust the item scores for acquiescence by either ipsativing data or modelling acquiescence as a latent variable. Ipsativing raw data can be done by computing a mean score across all 10 items and subsequently substracting that mean score from each item score (cf. Rammstedt et al., 2010; Rammstedt & Farmer, 2013; Rammstedt et al., 2013). Modelling acquiescence as a latent variable requires setting the path from the latent acquiescence variable to all manifest items to 1 whereas the path from the latent construct variables to the manifest items are freely estimated (Billiet & McClendon, 2000; Danner, Aichholzer, & Rammstedt, 2015).

Can I use the BFI-10 in different modes?

Yes, Rammstedt et al., 2013 have demonstrated that the factorial validity and the criterion validity of the BFI-10 is comparable in paper-pencil administration and in personal interviews.

Is the BFI-10 available in different languages?

Yes, the BFI-10 has been developed based on the German and the English items. In addition, the BFI-10 has been translated into various other languages, e.g., in the International Social Survey Programme (ISSP). Analyzing the data of the ISSP with multi-group structural equation models suggests that the BFI-10 is metrically invariant across the United States, Germany, New Zealand, Switzerland, Netherlands, Denmark, Ireland, and France. Be aware though that not all available translations have been validated.
