Investigating the Tribal Preference in Electoral Behavior and its Related Factors in Yasouj in the 11th Parliament Election

The ethnic electoral behavior researches in Iran have been mainly carried out in places with different ethnicities. Taking a different perspective, this research was conducted in Yasouj which includes a dominant ethnicity and tried to investigate the tribal preference in election behavior and its relationship with tribal identity and traditionalism. The statistical population of the study includes all the citizens who took part in the 11th parliament elections, among of which 406 people were selected using a multi-stage random sampling method. The research instrument for measuring the variables of traditionalism and tribal identity are two researcher-made questionnaires, which their validity and reliability were determined using the construct validity, and the Cronbach's alpha coefficient, respectively. In order to assess the tribal preference of the respondents, the adaptation of the answers of the participants to their chosen tribe and candidate was used. So, they were divided into two groups with tribal preference and without tribal preference regarding the parliament election. The descriptive findings of the research showed that, 38.6% of participant voted based on the tribal affiliations. On the other hand, the analytical findings using logistic regression analysis revealed that traditionalism and gender increase the probability of tribal preference in electoral behavior, but academic education decreases the tribal preferences regarding the voting behavior. Moreover, the variables of tribal identity, age, marital status, and employment status do not show any statistically significant relationship with the tribal preference in the electoral behavior.
