"There is wide variation in tightness-looseness that is distinct from other dimensions of culture, such as individualism-collectivism" (7990).
Tightness scores were calculated for each of the 50 states. A Welch ANOVA indicated variation in tightness-looseness at the regional level, with the South having the highest tightness scores and the West and Northeast having the lowest tightness scores (p< .001). The correlation between tightness-looseness and collectivism-individualism was only moderately significant, which suggests it is a distinct construct.
