ABSTRACT This paper examines the relationship between Hong Kong Chinese people's contact with transgender/transsexual (TG/TS) people and attitudes toward transgenderism and transgender civil rights, based on Allport's Contact Hypothesis. The term transprejudice is introduced to refer to the negative valuing, stereotyping and discriminatory treatment of TG/TS people. Data are presented from a population-based survey with a random sample of 856 Hong Kong Chinese persons aged between 15 and 64, using the Chinese Attitudes towards Transgenderism and Transgender Civil Rights Scale (CATTCRS). Attitudes, assessed on both personal and institutional dimensions, are examined in relation to participants’ gender, age, educational level, religiosity, and previous contact with transpeople. Results suggest that previous contact with transpeople was significantly associated with attitudes reflected in the scale; decreased social distance, decreased social discrimination, and decreased transprejudice, increased awareness of discrimination against transpeople, increased support for equal opportunities, increased support for post-operative transsexual civil rights, and increased support for anti-discrimination legislation. Our findings support the contact hypothesis, that contact has a positive effect on attitudes towards TG/TS persons. We discuss the implications of these findings for public education interventions and public policy, as well as for research.
