Abstract

Sufficient and efficient sleep can be affected by an individual’s behaviour such as mobile phone dependence and management of daily life stressors through the use of coping styles. The current study explored whether the components of Consensus Sleep Diary would predict the composite score of Pittsburgh Sleep Quality Index (PSQI). In total, 29 participants completed a seven-day Consensus Sleep Diary and a one-off questionnaire assessing mobile phone dependence, anxiety, coping styles and PSQI at the end of the survey. The regression findings revealed a significant model of the sleep diary components predicting composite score of PSQI, global PSQI, but none of the sleep components significantly contributed to the outcome. Relative to other diary components, effect sizes of Wake After Sleep Onset (WASO) and Number of Awakenings (NWAK) were greater. A model was hypothesized suggesting that level of anxiety, mobile phone dependence, rational coping, detached coping, emotional coping and avoidant coping would predict the global PSQI. Although the hypothesized model was significant, only detached coping and emotional coping significantly predicted the sleep quality and with large effect. Results suggested that overall sleep quality may have a greater association with sleep fragmentation components like WASO, NWAK as well as detached and emotional coping styles. Therefore, for better sleep, the general population should improve their sleep continuation and the way they manage stress. Implications involve promoting healthy coping styles in universities, the work-place, clinical settings and awareness campaigns.
