Objectives The paper examines how strongly non-physical peer sexual harassment is associated with a wide range of well-being outcomes from symptoms of depression and anxiety to self-esteem and body image. Methods Two large community samples of high school students were analyzed (n = 1384 and n = 1485). Students responded to questionnaires on being subject to nonphysical sexual harassment, sexual coercion and forced intercourse, and to well-being indicators ranging from anxiety, depression, self-esteem, body image. Results Regression analyses suggest that being harassed by peers in a non-physical way was moderately associated with lower levels of well-being over and above the effect of other risk factors. This effect was present for all indicators of well-being. The effect of peer harassment on depressive symptoms was moderated by sex (affected women more) but not by sexual or ethnic minority status. Conclusions The findings imply that although sticks and stones may break bones, it does seem that derogatory words and other forms of non-physical sexual harassment definitely harm high school students.
