We examine the validity and reliability of a single‐item measure of social identification (SISI). Convergent validity is shown with significant positive correlations with previously published unidimensional and multidimensional measures of in‐group identification and other group‐relevant measures (e.g., entitativity and collective self‐esteem). Divergent validity is shown via nonsignificant correlations with social desirability measures. Predictive validity is shown with positive correlations with group‐relevant behavior (e.g., volunteerism and voting). External validity is shown with correlations with other in‐group identification measures in a community sample. The reliability of the scale is shown by examining scores of the SISI for six different identities at three points in time. Copyright © 2013 John Wiley & Sons, Ltd.
