The Modified Overt Aggression Scale (MOAS) has been validated for use in the study of aggression in the developed world; unlike in the undeveloped world. The aim of this study therefore is to ascertain the discriminant validity of the MOAS for use in this part of the world using psychiatric in-patients at the Jos University Teaching Hospital.
Forty aggressive psychiatric patients and 40 non-aggressive healthy subjects were randomly selected for this study. The psychiatric patients were enlisted after fulfilling the ICD-10 (World Health Organization, 1993) criteria for a specific clinical diagnosis. The 40 non-aggressive subjects were mainly medical students and hospital staff. The MOAS was subsequently used to assess aggression in the entire cohort.
The males had higher mean global weighted score than the females in both the aggressive and nonaggressive categories. The mean global weighted scores of the aggressive and non-aggressive categories were 13.70 +/- 7.25 and 0.65 +/- 1.01 respectively. The difference in means is statistically significant; hence the MOAS has discriminant validity.
Therefore, the modified overt aggression scale is a valid instrument in this environment for the study of aggression.
修订版公开攻击量表（MOAS）已在发达国家的攻击行为研究中得到验证；但在不发达国家情况不同。因此，本研究的目的是利用乔斯大学教学医院的精神科住院患者，确定MOAS在世界这一地区使用时的区分效度。
本研究随机选取了40名有攻击行为的精神科患者和40名无攻击行为的健康受试者。精神科患者在满足ICD-10（世界卫生组织，1993年）特定临床诊断标准后被纳入。40名无攻击行为的受试者主要是医学生和医院工作人员。随后使用MOAS对整个队列的攻击行为进行评估。
在有攻击行为和无攻击行为的类别中，男性的平均总体加权得分均高于女性。有攻击行为和无攻击行为类别的平均总体加权得分分别为13.70±7.25和0.65±1.01。均值差异具有统计学意义；因此，MOAS具有区分效度。
因此，修订版公开攻击量表在这种环境下是研究攻击行为的有效工具。
