Abstract
The present study examined the relationship between Intolerance of Uncertainty, Anxious Distress and sleep quality among university Students. A quasi-research design was employed, using purposive sampling to collect data from university students (N = 200), aged 18 to 25 years (M = 22.36, SD = 2.21). The scales used in this study included Intolerance of Uncertainty Scale (IUS-12; Carleton et al., 2007), State Trait Anxiety Inventory (STAI; Spielberger et al., 1983), and Sleep Quality Scale (SQS; Yi et al, 2006). Results in this study is as following. Correlation showed that Intolerance of Uncertainty was positively correlated with Anxious Distress and Sleep Quality. There was also a positive correlation between Anxious Distress and Sleep Quality. Regression showed that Intolerance of Uncertainty and Anxious distress are significant predictor of sleep quality among university students. Mediation indicated that Anxious Distress partially mediated the relationship between Intolerance of Uncertainty and Sleep Quality. For intervention study following test were done. Mann Whitney U test was done to compare the scores on anxious distress and sleep quality, between experimental and control groups. The results showed that Positive Prospective Mental Imagery intervention was significantly able to reduce anxious distress among experimental group. Sleep quality was also improved through the intervention as the scores were reduced in experimental group than control group but the significance was on borderline level. Wilcoxen Signed-Rank analysis was done to compare pre and post scores on anxious distress and sleep quality after the intervention. The results showed statistically significant reduction in both scores after the intervention in experimental group.
