The study tested the predicted differences in phenomenology (self-esteem and depression) and insecurity of the subgroups of paranoia proposed by the Trower and Chadwick (1995) model of paranoia. Thirty-two inpatients experiencing persecutory delusions were assigned to either the poor me or bad me paranoid group. Questionnaire assessment of depression and self-esteem were conducted. A Dot Probe task measured detection latency (reaction time) to poor me words, bad me words and neutral words. The poor me and bad me groups displayed the predicted phenomenological differences. The dot probe task did not support the predicted insecurities of the Trower and Chadwick model, but unexpected significant results for the poor me subgroup may offer support for an alternative explanation of paranoia as an unstable phenomenon.
该研究检验了 Trower 和 Chadwick（1995 年）妄想模型中妄想亚组的现象学（自尊和抑郁）和不安全感的预测差异。32 名患有被害妄想的住院患者被分配到“可怜的我”或“邪恶的我”妄想组。通过问卷调查评估抑郁和自尊。点探测任务测量对“可怜的我”、“邪恶的我”和中性词的检测潜伏期（反应时间）。“可怜的我”和“邪恶的我”两组表现出预期的现象学差异。点探测任务不支持 Trower 和 Chadwick 模型的预测不安全感，但对“可怜的我”亚组的意外显著结果可能为将妄想解释为不稳定现象提供了替代解释。
