The present study aimed at the mediator role of cognitive flexibility in the relationship between insomnia catastrophizing and dispositional hope. Two separate models were tested for the nighttime and daytime forms of insomnia catastrophizing. Insomnia catastrophizing nighttime form was included as independent variable in the first mediator model and insomnia catastrophizing daytime form was included as independent variable in the second mediator model. Dispositional hope was the dependent variable and cognitive flexibility was the mediator variable. The study group consisted of 438 volunteer young adults, the majority of whom were undergraduate students (N = 313, 71.5%). 360 (82.2%) of the study group consisted of female participants. The age range of the group was 16–46 and the mean age was 21.53 (SD = 3.08). 78 of the participants (17.9%) declared that they slept less than 6 hours a day on average, and 204 (46.5%) declared that they slept an average of 7-8 hours a day. The data of the study were collected with the Insomnia Catastrophizing Scale (Nighttime and Daytime Forms), the Cognitive Flexibility Scale, and the Dispositional Hope Scale. Data was collected online. Before the analysis, the missing data, extreme values, and the assumption of normality were analyzed first. Then, Process macros developed by Hayes were applied to test the mediator models. Mediator models were tested using SPSS v24 with 5000 resampling methods from Bootstrapping. Research findings showed negative relationships between nighttime and daytime forms of insomnia catastrophizing and dispositional hope and cognitive flexibility. However, in both mediator models tested, the mediator effect of cognitive flexibility was found to be significant in the relationship between insomnia catastrophizing and dispositional hope. The power to explain the dispositional hope of both mediator models was 53%. We discussed the current findings and presented some suggestions to mental health practitioners.
