Paranoid ideation, a crucial component of psychotic-like experiences, tends to increase between early and late adolescence, even in the general population, and it negatively affects overall mental health and social adjustment. Japanese adolescents experience high levels of interpersonal stress. However, few studies have examined the relationship between paranoid ideation and interpersonal stress. This study investigated the effects of maladaptive metacognitive beliefs and interpersonal stress on paranoid ideation to provide suggestions for preventive education and early intervention for paranoid ideations among Japanese university students.
An online questionnaire survey involving 400 Japanese university students, aged between 18 and 22 years, was conducted. The questionnaires used were the Paranoia Checklist, the Metacognitive Questionnaire-30, and the Interpersonal Stressor Scale. The Interpersonal Stressor Scale was developed specifically for Japanese adolescents.
A multiple regression analysis was performed, which showed that the regression coefficients of the interaction between maladaptive metacognitive beliefs and interpersonal stress were significant for paranoid ideation. The results of the simple slope analysis regarding the scales on which interactions were found also indicated that the influence of maladaptive metacognitive beliefs on paranoid ideation was greater when interpersonal stress levels were higher.
The combination of interpersonal stress and maladaptive metacognitive beliefs exacerbates paranoid ideation among Japanese university students. It is important to modify metacognitive and cognitive biases in preventive education and early intervention strategies.
偏执观念是类精神病体验的一个关键组成部分，即使在普通人群中，也往往会在青春期早期到晚期之间增加，并且会对整体心理健康和社会适应产生负面影响。日本青少年经历着高水平的人际压力。然而，很少有研究探讨偏执观念与人际压力之间的关系。本研究调查了适应不良的元认知信念和人际压力对偏执观念的影响，以便为日本大学生偏执观念的预防教育和早期干预提供建议。
对400名年龄在18至22岁之间的日本大学生进行了在线问卷调查。所使用的问卷包括《偏执清单》《元认知问卷 - 30》和《人际压力源量表》。《人际压力源量表》是专门为日本青少年编制的。
进行了多元回归分析，结果表明，适应不良的元认知信念与人际压力之间的交互作用的回归系数对偏执观念具有显著影响。关于发现存在交互作用的量表的简单斜率分析结果还表明，当人际压力水平较高时，适应不良的元认知信念对偏执观念的影响更大。
人际压力和适应不良的元认知信念的结合会加剧日本大学生的偏执观念。在预防教育和早期干预策略中改变元认知和认知偏差很重要。
