Summary
Brief summary (as posted)
Cancer is one of the major causes of death in pediatric population. In Hong Kong, childhood cancer remains a significant concern in healthcare system because of its damaging impacts on adolescent's physical and psychological functions throughout their lifespan. Particularly, adolescents surviving cancer still have to bear the health burden of numerous sequelae, even their treatment is completed for months and even years. One of the most prevalent symptoms reported by patients surviving cancer is sleep disturbance. The causes of sleep disturbance are multifactorial. However, it can largely be attributed to disruption of circadian rhythm by prolonged use of medications and long-term hospitalization. Experiencing sleep disturbance can be devastating for survivors of cancer and precipitates inflammation and oxidative stress, which are known to be a contributing factor of neurocognitive impairment. Sleep disturbance can also lead to fatigue, which in turn limits patients' capacity in engaging in daily activities and even results in depression, severely compromising patients' quality of life in the long run. Having a reliable and valid instrument that can precisely assess the problem of sleep disturbance of cancer survivors is therefore crucial for the development and evaluation of the intervention. The Pittsburgh Sleep Quality Index (PSQI) is the most commonly and frequently used instrument to assess sleep disturbance. Because of differences in culture and language, some concepts or items in the English version may be inappropriate for adolescents living in Hong Kong. Moreover, the psychometrics of the PSQI has only been established in adolescents undergoing active treatment for cancer, when they experienced the most severe problem. It is therefore unclear whether the PSQI can also be used to assess sleep disturbance of adolescents who have completed cancer treatment. This lack of validated instruments precludes us from understanding the severity of the problem. Also, it hinders the development of appropriate interventions that promote sleep quality. This study aims to bridge the gap in existing literature by translating the PSQI from English into Chinese, and examining the psychometrics of the translated PSQI in Hong Kong Chinese childhood cancer survivors.
