Structural Relationships between Paranoid Thoughts, Rumination, Insomnia, and Negative Emotions

The aim of this study was to investigate the structural relationships between anxiety, rumination, insomnia and negative emotions with paranoid thoughts. The research design is descriptive-correlational. For this purpose, 240 students of Amirkabir University were selected using cluster sampling and given the Pennsylvania Concern Questionnaire, NalinHaxma Ruminant Scale, Depression, Anxiety and Stress Scale of Loebond, Bostin Insomnia Scale, and Paranoid Thought Scale. Which was given to them, they replied. Data analysis was performed using structural equation modeling. Also, SPSS 22 and LISREL 85.8 statistical software were used to classify, process and analyze the data and test the research hypotheses. Evaluation of the hypothetical model of the research using fitness indicators showed that the hypothetical model fits with the measurement model (CFI = 0.98, NFI = 0.96, RMSEA = 0.048). The results showed that insomnia indirectly affects paranoid thoughts through negative emotion and worry and rumination and also negative emotion indirectly affects paranoid thoughts through rumination and worry. Based on the research findings, it can be concluded that negative emotion and worry and rumination play a mediating role in the relationship between insomnia and paranoid thoughts. Paying attention to this mechanism of effect can be effective in formulating effective preventive and therapeutic interventions to reduce paranoid thoughts.
