Four hundred and sixty-six subjects (233 males, 233 females; the mean age = 23, age range: 18 - 32 years) from 10 public universities participated in this study. They were students of art (2), medicine (57), engineering (104), psychology (25), humanity science (115), experimental science (62), arithmetic (39), and seminaries (62). Most were Shiite (383) and 83 were Sunnis (
Table 1). They got rollerball pen and signed an informed consent.
In the first scenario (rape) 196 subjects (42.1%) agreed with prison sentence and 265 (56.9%) with capital punishment (159 or 34.1% suggested painful death penalty and 106 or 22.7% nonpainful, χ
2 = 10.14, df = 1, P < 0.001) (
Table 2). In the second scenario (adultery) agreement with prison sentence was seen in 296 subjects (63.5%) and 97 subjects (20.8%) suggested death penalty (45 or 9.6% painful and 52 or 11.2% painless execution, χ
2 = 0.71, df = 1, P < 0.001). In the third one (murder), 264 subjects (56.6%) agreed with prison sentence and 194 (41.6%) agreed with execution (32 or 6.9% painful and 161 or 34.6% painless, χ
2 = 59.57, df = 1, P < 0.001). In the last legal scenario (drug trafficking), agreement with the prison sentence was observed in 134 subjects (28.8%) and with death penalty was reported in 322 subjects (69.1%) (133 or 28.5% painful and 189 or 40.6% painless execution, χ
2 = 8.82, df = 1, P < 0.001). In the fifth scenarios (euthanasia for conscious cancer patients), 181 subjects (39.4%) selected active euthanasia, 54 (11.8%) selected passive euthanasia and 224 (48.8%) suggested to treat the patient as far as possible. Active euthanasia had significantly more proponents than passive euthanasia (χ
2 = 23.26, df = 1, P < 0.001). In the sixth scenario (euthanasia for unconscious cancer patients), 137 subjects (30.45%) selected active euthanasia, 74 (16.45%) selected passive euthanasia and 239 (53.1%) suggested to treat the patient as far as possible. Also, active euthanasia had significantly more proponents than passive euthanasia (χ
2 = 12.07, df = 1, P < 0.001) (
Table 3).
4.1. Intensity of Individual Responses to Scenarios
The multivariate analysis of variance was performed to compare responses to the first four scenarios. The subjects’ responses were different toward rape (M = 46.90, SD = 9.34), adultery (M = 29.97, SD = 11.83), murder (M = 36.57, SD = 7.59), and drug trafficking (M = 37.46, SD = 8.15), (F (3.46) = 347.21, P < 0.01 partial Eta squared = 0.69, P < 0.001). The pairwise comparison of scenarios, with Bonferroni correction, was significant for all scenarios (P < 0.01) except for the third and fourth scenarios (murder and drug trafficking). Thus, participants responded more aggressively to rape than drug trafficking, murder, and adultery. The results of MANOVA for the fifth (M = 15.07, SD = 6.55) and sixth (M = 13.98, SD = 6.18) scenarios (euthanasia) showed a significant effect as well (F (1.465) = 12.58, P < 0.01, partial Eta squared = 0.03, P < 0.001] and the individuals had a positive attitude toward euthanasia for conscious patients.
The mean score was also calculated for each scenario to evaluate the effects of gender in the six subscales of JDAS. The result of MANOVA showed a significant effect for gender (F (6, 399) = 2.62, P < 0.001). Males significantly scored higher on scores of murder subscale (F (1, 404) = 9.58, P < 0.01 partial Eta squared = 0.023).
Meanwhile, the JDAS mean score was compared in the following four groups of academic majors: humanities, medical sciences, engineering, and life sciences (
Table 1). The result of MANOVA indicated a significant effect (F (18, 1123.37) = 1.75, P < 0.05]. Subsequent tests of between-subject effects illustrated that the major group (consisted of students across all majors) significantly scored differently on rape (F (1, 404) = 9.58, P < 0.01, partial Eta squared = 0.02). The Bonferroni`s multiple comparisons of the four groups demonstrated a higher score of rape by the group of experimental sciences in comparison with humanities and physics (P < 0.001).
To evaluate the effects of religion on the six subscales of JDAS, the MANOVA was conducted. The result of MANOVA illustrated a significant effect, (F (6, 46) = 7.23, P < 0.001). Subsequent tests of between-subject effects showed that religious people, in comparison to others, scored significantly higher on rape (F (1, 464) = 11.98, P < 0.01, partial Eta squared = 0.02), adultery (F (1, 464) = 20.61, P < 0.01, partial Eta squared = 0.04), murder (F (1, 46) = 5.07, P < 0.01, partial Eta squared = 0.01), drug trafficking (F (1, 46) = 10.60, P < 0.01, partial Eta squared = 0.02), and lower on euthanasia for conscious patients (F (1, 46) = 9.60, P < 0.01, partial Eta squared = 0.02), and euthanasia for unconscious patients (F (1, 46) = 14.75, P < 0.01, partial Eta squared = 0.03).
To evaluate the effects of mental health status on the six subscales of JDAS, another MANOVA was performed. The result of MANOVA indicated a nonsignificant effect on first order factors, F (6, 459) = 1.16, P > 0.05, and the second order ones, F (2, 46) = 1.15, P > 0.05).
