MMPI-2评估应激障碍的效果

Assessing with the MMPI-2 for Stress Disorders

目的:采用MMPI-2评估应激障碍(SD)患者的病理心理特征,并探讨其辅助诊断的应用价值。方法:实验组为入院治疗的29名急性应激障碍(ASD)患者及14名创伤后应激障碍(PTSD)患者,对照组为44名适应良好的应激创伤幸存者,在不影响测验症状的情况下完成MMPI-2测试。结果:ASD患者MMPI-2的F、Fb、Fp、Pa、Pt、Sc和Ma的因子得分高于对照组,K和S低于对照组,差异有统计学显著性(P<0.05-0.001);PTSD患者F、Fb、Fp、Hs、D、Hy、Pa、Pt和Sc高于对照组,S低于对照组,差异有统计学显著性(P<0.05-0.001);ASD患者Hs、D和Hy低于PTSD患者,差异有统计学显著性(P<0.05-0.001)。两组患者剖面图均呈M678型。Pa和Sc进入判别函数,该函数在训练样本和验证样本中的预测符合率分别为83.9%和72.0%。结论:SD患者和适应良好的创伤幸存者的心理病理表现明显不同,ASD患者和PTSD患者的症状特征也有所差异;MMPI-2对应激失常症状比较敏感,Pa和Sc具有较好的鉴别能力。

Objective: To investigate psychopathology and diagnostic efficiency with MMPI-2 in patients with stress disorder (SD). Methods: MMPI-2s were administered to twenty-nine patients with acute stress disorder (ASD), fourteen patients with posttraumatic stress disorder (PTSD) and forty-four well-adjusted trauma survivors. Results: Patients with ASD obtained significantly higher scores on F, Fb, Fp, Pa, Pt, Sc and Ma and lower on K, S than controls. PTSD patients scored significantly higher on F, Fb, Fp, Hs, D, Hy, Pa, Pt and Sc and lower on S than controls. There were significant differences in scores of Hs, D and Hy between patients with ASD and with PTSD. M678 code type was found as the mean profile for SD patients. Discriminate analysis indicated that Pa and Sc were the most important variables and it successfully classified 83.9% and 72.0% respectively in training sample and cross-validation sample. Conclusion: Patients with SD and trauma survivors show significantly different psychopathology and there were also differences between patients with ASD and with PTSD. MMPI-2 scales especially Pa and Sc were sensitive to posttraumatic stress symptoms.
