Insomnia is one of the most frequently encountered problems among women with breast cancer. The aims were to identify the classes of the insomnia symptoms and to evaluate their effects on quality of life in women with breast cancer. 287 women with breast cancer were recruited to complete measures at six time-points lasting for 4 months. Four distinct classes of insomnia symptom were identified using growth mixture modeling, named Low sustained class, High sustained class, Moderate sustained class and Decreasing class. In these four classes, women in low sustained class had highest scores of social/family and functional well-beings, but those in high sustained class had highest scores of physical well-being and additional concerns. Besides, no significant difference was found in emotional well-being. These results suggest sustained high level of insomnia symptoms can reduce physical well-being and additional concerns but not emotional well-being in Chinese women with breast cancer.
