摘要：Abstract The purpose of this study was the comparison of personal behavior styles in clinical depressed, non-clinical depressed and normal people. 151 persons including 31 clinical depressed, 60 non-clinical depressed persons and 60 normal persons were asked to complete questionnaires assessing Personal Behavior Style (PBI) and Beck Depression Inventory (BDI). Result revealed that Non-clinical depressed group has used inner control more than clinical depressed group but used other control style less than them. Normal group has used inner control style of behavior more than non-clinical depressed group but they have used other control style less than them. In response to study questions, results showed non-clinical depressed people had more lack of constraints and predictability in compare with clinical depressed people. Inner control style which has a positive relation with depression is a powerful predictor for depression. People who have Inner control style of behavior believe that their efforts are effective and they try to reach their goals. This kind of attitude protects them against depression.
