Two studies examined the relationship between the General Factor of Personality (GFP) and behavioral inhibition and anxiety symptoms in primary school children. The GFP is assumed to reflect effectiveness in interaction with others. In Study 1, using self-reports and parent ratings of 226 non-clinical children, we found GFP scores to be negatively related to behavioral inhibition and anxiety symptoms. In Study 2 we compared non-clinical children (N = 81) with children with anxiety disorders (N = 45). In both groups we obtained child and parent ratings. The clinically referred children scored significantly lower on the GFP than the non-clinical children. Moreover, as in Study 1, higher GFP scores were associated with lower levels of behavioral inhibition and anxiety symptoms. The two studies support the view that the GFP is a relevant construct in anxiety proneness and anxiety problems.
