... analysis. The Value-Expressive subscale was not confirmed and showed poor reliability. Pro-and anti-gay rights behavior was measured using a Political Behavior Index (PBI) developed for this study. Regression analyses and MANOVAs were employed to test six hypotheses, all of which received some support. Pro-gay rights behavior was associated with Experiential-Schematic attitudes and a Value-Expressive item regarding civil liberties. Anti-gay rights behavior was associated with Ego-Defensive attitudes and a Value-Expressive item regarding moral beliefs. Men scored higher on the Ego-Defensive function than did women. Those who knew more gay people were more likely to exhibit Experiential-Schematic attitudes and were less likely to hold Ego-Defensive attitudes. These findings imply that efforts to change anti-gay rights behavior need to address the underlying motivations of Ego-Defense and Value-Expression regarding the construct of moral beliefs. An additional implication is a potential for increasing support for the legal rights of gay people by increasing association with people one knows to be gay.
