بررسی رابطه متغیر شخصیتی افزایش‌دهنده‌ و کاهش‌دهنده درد (میزان تحمل درد در افراد) و سلامت روانی

 This research aimed to study the relationship between the personality variable of augmenter and reducer of pain, and mental health as well as studying the pain tolerance of individuals in relation with mental health related variables. Researchers have given due attention to many variables, but in spite of their supposition, factors such as age and gender have been less influential on pain tolerance rate. Psychological factors such as perception, flexibility, fear, previous experience and feedback, and job dissatisfaction influence the pain tolerance. Those with internal control – based on Jolian theory, show a further adaptation capability. Introverts compared with extroverts – based on Izinc studies – show a lower pain tolerance. Among cultural and social groups, essential differences are reported. Some cultural, religious, racial and social groups have demonstrated a higher degree of pain tolerance.  Regarding personality structure influence on reaction towards pain they are divided into two groups of augmenters and reducers of pain. The second group (reducers) showed more resistance towards pain and in fact they are perceptional reducers. But augmenters were sensitive to external stimuli and they are in fact perceptional augmenters. Statistical sample were the students of the international university who were selected through a staging sampling. 80 students were chosen. A general health questionnaire and a researcher made questionnaire for measuring personality variables of augmenter and reducer of pain were used as research instruments. All students filled out the two questionnaires.  The results showed a strong correlation between personality and mental health variables. The correlation rate was 494% and was significant at 5% and 1% levels. No significant correlation was observed between pain tolerance and the general health mark.
