چکیده (انگلیسی):

Relations between Neuroticism, Republican-Democrat preference, and conservative-liberal ideological orientation were
examined with the states of the USA as units of analysis. State-aggregated Neuroticism scores were based on 1999-2005
responses of 619,397 residents to the 44-item Big Five Inventory . State Republican-Democrat preference was based on the
2002 occupancy of the U.S. Presidency, U.S. House, U.S. Senate, state House, state Senate, and state Governorship, as
well as state-aggregated partisanship responses of 1 10,305 persons to 1998-2002 CBS/New Y ork Times national polls. State
conservative-liberal ideological orientation was based on 1998-2002 state-aggregated responses of 103,828 persons to
CBS/New Y ork Times national polls. Using correlation, partial correlation, and hierarchical multiple regression, it was determined
that lower state resident Neuroticism is associated with Republican preference, and that both conservative-liberal ideological
orientation and state resident Neuroticism account independently for variance in Republican-Democrat preference. These
relations were found when 1998-2002 state socioeconomic status, white percent, and urban percent were statistically considered
and controlled in partial correlation and hierarchical regression analysis. In contrast, corresponding analyses involving the
other Big Five showed that only Openness and Conscientiousness showed any relation to partisanship, albeit infrequent and
inconsistent. State resident Neuroticism is the primary state-level Big Five predictor of Republican/Democratic Party choice.
