Abstract

This study investigated the relationships of paranoia and depression to the state-trait anger, the mode of anger expression, and the attributional and reasoning style. The Paranoia Scale, the Zung Depression Inventory, the State-Trait Anger Expression Inventory, the Attributional and Reasoning Style Questionnaire were administered to 247 college students. The results showed that the state and trait anger, anger-in, and anger-out were significantly correlated to the ratings on hostility and frequency of the negative social events. The anger-control was negatively correlated. The paranoid tendency was significantly correlated to state-trait anger, anger-in, anger-out, and defensive and hostile attributions. The depression score was significantly correlated to state anger, low anger-control, and self-accusing attribution. The paranoid group showed more state-trait anger, anger-in, anger-out, and rated positive events as more hostile, and rated negative social events as occurring more frequently in comparison to control group. The suggestions and the limitations of this study, and the directions of future study were discussed.
