The first survey had 473 participants, while the second had 692 participants. The questionnaire for the first survey had 51 items, while that for the second survey had 58 items, including reworded items and new items. The questions focused on knowledge of facts about suicide, attitudes toward and feelings about suicide, suicide ideation, suicidal behavior, and contact with others who had attempted or completed suicide. Results revealed sex differences in receptivity to suicidal individuals, beliefs about the behavior or suicidal peers, attitudes concerning the worth of suicidal people, incidence of adolescent suicide, and morality of suicide. The majority of the students of both sexes recognized that people close to them might be suicidal, did not judge suicidal individuals harshly, and were supportive of the needs of suicidal people. However, a higher proportion of males than females lacked these qualities. No sex differences were found in the participants' own frequency or seriousness of suicide ideation or suicide attempts.
