For the 1.8 million people diagnosed with cancer every year, many will undergo long and challenging treatments that are administered intermittently or continuously across their lifespan (Siegel et al., 2018). In addition to coping with a variety of potential side effects of treatment, including physical pain, fatigue and disability, patients often struggle with the psychosocial side effects of cancer, including feelings of hopelessness and depression, isolation, fear, anger/ frustration, loss of purpose and meaning in life, and uncertainty about the future (Astrow et al., 2001;Dein, 2013;Pargament et al., 2004;Puchalski, 2013). Therefore, cancer survivors may be especially vulnerable to existential and spiritual crisis. Unfortunately, despite the advances in the biomedical care and treatment of cancer, there has been less attention paid to improving the provision of spiritual care for cancer patients (Best et al., 2015).
