ABSTRACT
OBJECTIVE: The COVID-19 outbreak has adversely affected breast cancer patients both physically and mentally. Managing Cancer and Living Meaningfully (CALM) is a psychological intervention that is easy to implement. It also decreases the possibility of virus transmission because it can be administered online. Therefore, this study investigated the effects of CALM on the sleep quality, memory, psychological distress, and quality of life (QoL) of breast cancer patients during the ongoing COVID-19 pandemic. METHODS: Sixty breast cancer patients were recruited and randomly assigned to a CALM group and a Care as Usual (CAU) group. They filled in questionnaires before and after the CALM intervention and CAU. These included the Sleep Quality Scale (SQS), Prospective Memory Scale (PM), Retrospective Memory Scale (RM), Psychological Distress Thermometer (DT), and Quality of life (QoL) Scale. RESULTS: The scores of all the aforementioned scales after the CALM intervention (ACM) were significantly lower compared to the said scores before the CALM intervention (BCM) and after Care as Usual (ACU) (t = 12.369/8.013, t = 8.632/4.583, t = 7.500/6.900, t = 12.479/9.780, t = 12.224/6.729 respectively, P < 0.05) There was a linear correlation between the QoL, DT, and SQS scores. CONCLUSION: CALM is an effective psychotherapy for breast cancer patients, especially during the COVID-19 pandemic, for improving the QoL because it relieves psychological distress and enhances sleep quality.
