We are pleased to announce that the 2-year impact factor for the Division 49 journal Group Dynamics has risen to 1.64 for the year 2017. This represents a significant increase from the previous year and puts Group Dynamics within the top 50% of journals in its category. The impact factor represents the number of times journal articles are cited by other scholars in a given year relative to the number of articles published. Congratulations to the editor, David Marcus and his team of associate editors for this achievement.
