Previous studies have demonstrated that individuals with methamphetamine dependence have impaired emotion recognition. However, heterogeneity in results from these studies may indicate that individual factors such as personality beliefs moderate emotion recognition deficits. Thus, we aimed to examine the relationship between dimensional estimates of dysfunctional personality beliefs and facial emotion recognition in 86 Australian treatment seekers with methamphetamine dependence. Dysfunctional beliefs were measured using the Personality Beliefs Questionnaire, and emotion recognition was measured with the Ekman's Faces Test. We applied hierarchical regression analyses to test the relationship between beliefs and emotion recognition after accounting for the effects of intelligence. Results indicated that personality beliefs reflecting antisocial and paranoid schemas together accounted for a significant increase in the variance in fear recognition (higher levels of beliefs associated with poorer fear recognition). Further, high levels of passive-aggressive personality beliefs were associated with a tendency to misclassify faces as disgust. Our findings suggest that antisocial, paranoid, and passive-aggressive dysfunctional personality beliefs may underlie inter-individual differences in emotion recognition in methamphetamine dependent individuals. Additional research is required to better understand the relationship between personality and social processing biases, and investigate the direct impact these have on the significant psychosocial impairments present in individuals with methamphetamine dependence.
先前的研究表明，冰毒依赖者的情绪识别能力受损。然而，这些研究结果的异质性可能表明，个体因素如人格信念会调节情绪识别缺陷。因此，我们旨在研究澳大利亚 86 名冰毒依赖治疗者的功能失调人格信念的维度估计与面部情绪识别之间的关系。使用人格信念问卷测量信念，使用埃克曼人脸测试测量情绪识别。我们应用层次回归分析，在考虑智力影响的情况下，测试信念与情绪识别之间的关系。结果表明，反映反社会和偏执图式的人格信念共同解释了恐惧识别变异性的显著增加（信念水平越高，恐惧识别越差）。此外，高水平的被动攻击型人格信念与将面孔错误归类为厌恶的倾向有关。我们的研究结果表明，反社会、偏执和被动攻击型功能失调人格信念可能是冰毒依赖个体情绪识别个体差异的基础。需要进一步研究以更好地理解人格与社会加工偏差之间的关系，并研究这些偏差对冰毒依赖个体存在的重大心理社会障碍的直接影响。
