What is the temperamental basis of humour like in China? A cross-national examination and validation of the standard version of the state-trait cheerfulness inventory.

The State-Trait Cheerfulness Inventory-trait version (STCI-T60) consists of three dimensions of cheerfulness, seriousness, and bad mood integrated to measure the temperamental basis of the sense of humour. The present study replicated the three-dimensional factor structure of the STCI in China using 60 items consistent with other standard trait versions (e.g., English, Chilean-Spanish). Closer examination of associations between traits suggested bad mood showed curvilinear associations with both cheerfulness and seriousness, such that cheerfulness and bad mood were negatively associated for those low and average in trait bad mood but not for those with high trait bad mood. Seriousness was positively associated with bad mood at high levels of trait bad mood, but not at average or low levels of bad mood. Associations between the STCI traits and major personality dimensions, humour styles, and well-being were further examined. Cheerfulness and seriousness showed positive associations with satisfaction with life and emotional well-being (EWB) while bad mood showed a curvilinear association with EWB. Using multi-group confirmatory factor analyses, partial metric invariance was found between English and Chinese versions of the STCI-T60, but structural invariance was not observed. Implications based on the empirical literature in dialecticism and cross-cultural assessment were thoroughly discussed.
