The goal of this study was to examine the relationships between cognitive distortions, self-compassion, and insomnia severity. Individuals were assessed using the Inventory of Cognitive Distortions (ICD), Self-Compassion Scale (SCS), and Insomnia Severity Index (ISI). Data were analyzed using a sample of 67 participants, ranging in age from 18 to 74. A simple linear regression analysis was conducted to test the hypothesis that cognitive distortions would be predictive of insomnia severity. The results were not significant. A multiple regression analysis was used to test the hypothesis that the specific cognitive distortions of fortunetelling, labeling, and jumping to conclusions would be predictive of insomnia. The hypothesis was not supported. Lastly, a correlation analysis was used to test the hypothesis that self-compassion would be inversely correlated with insomnia. The results revealed that the correlation coefficient between these variables was not significant. Though research has demonstrated a relationship between negative beliefs about sleep and insomnia, the results of this study indicated that although certain negative sleep beliefs align with specific distortions, cognitive distortions overall and the distortions evaluated were not predictive of insomnia. Additionally, though past research has demonstrated a significant relationship between self-compassion and sleep quality, a direct relationship between insomnia and self-compassion was not found. Based on these results, future research is necessary, with a larger, more diverse sample, to further assess these relationships.
