Immigrants have heightened risks of psychotic disorders, and it is proposed that migration influences symptom profiles. The purpose of this study was to investigate if either migration experience and/or visible minority status affected symptom profiles, using a cross-culturally validated five-factor model of the Positive and Negative Syndrome Scale (PANSS), in patients with broadly defined psychotic disorders.
PANSS was assessed in a large catchment area based sample of patients with psychotic disorders verified with the Structured Clinical Interview for DSM-IV (n = 1,081). Symptom profiles based on Wallwork et al. five-factor model were compared for Norwegians (73 %), white immigrants (10.5 %), and visible minority groups (16.5 %).
Visible minorities were significantly younger, had less education, more often a schizophrenia diagnosis and higher PANSS positive, negative and disorganized/concrete factor scores than Norwegians and white immigrants. After controlling for confounders only the items "Delusions" and "Difficulty in abstract thinking" differed between groups. Multivariate analyses indicated that these items were not associated with immigration per se, but rather belonging to a visible minority.
We found mostly similarities in psychotic symptoms between immigrants and Norwegians when using a cross-culturally validated five-factor model of the PANSS. Immigration did not directly influence psychotic symptom profiles but visible minority groups had higher levels of "Delusions" and "Difficulty in abstract thinking", both symptoms that are partially context dependent.
移民患精神病障碍的风险较高，有人提出，移民会影响症状特征。本研究旨在通过跨文化验证的阳性和阴性综合征量表（PANSS）五因素模型，调查移民经历和/或少数族裔身份是否会影响广泛定义的精神病障碍患者的症状特征。
在一个基于大样本的精神病障碍患者中，使用DSM-IV 结构临床访谈（n=1081）对 PANSS 进行评估。根据 Wallwork 等人的五因素模型，对挪威人（73%）、白种移民（10.5%）和少数族裔群体（16.5%）的症状特征进行比较。
少数族裔患者明显更年轻，受教育程度更低，更常被诊断为精神分裂症，阳性、阴性和紊乱/具体因子评分也更高。在控制混杂因素后，只有“妄想”和“抽象思维困难”这两个项目在组间存在差异。多变量分析表明，这些项目与移民本身无关，而是与少数族裔有关。
当使用跨文化验证的 PANSS 五因素模型时，我们发现移民和挪威人之间的精神病症状大多相似。移民并没有直接影响精神病症状特征，但少数族裔群体的“妄想”和“抽象思维困难”症状水平更高，这两个症状在一定程度上与环境有关。
