S exual harassment in public places is a common yet understudied form of gender-based aggression directed against females. [1-4] The aim of the present study was to investigate three different forms of sexual harassment in public places against women in Pakistan, as well as reactions to the harassment. Any physical, verbal, or nonverbal behaviour of a sexual nature that is not welcomed by the victim falls under the definition of sexual harassment. [1,5,6] Sexual harassment should be differentiated from flirting; sexual harassment is unwelcomed and unreciprocated, whereas flirting is based on mutual attraction. [5,7,8] Flirting, however, turns into sexual harassment if the act is Introduction: The study was aimed at investigating three types of sexual harassment in public places in Pakistan. Methods: A questionnaire was completed by 543 female students in Pakistan (M=22.3 years, SD 4.3). The questionnaire included scales for measuring physical, verbal, and nonverbal sexual harassment, and four scales measuring reactions to sexual harassment. Results: Sexual harassment was found to be most common in market places, and the perpetrator was typically a stranger. Nonverbal sexual harassment was the most frequent type. Only 2.8% of the respondents had never been victimised from any of the three types of sexual harassment. The most common reaction of the victims was to run away. Respondents highly victimised from physical, verbal or nonverbal harassment scored higher than others on defensive reactions, immediate distress, and long-term negative concomitants. Educational level was not associated with the amount of victimisation from any type of sexual harassment, but respondents with a high education scored significantly higher on negative reactions to sexual harassment. Discussion and Conclusion: Sexual harassment was associated with negative psychological concomitants for the victims. It can be concluded that sexual harassment in public places in Pakistan is a huge social problem that needs to be addressed.
