Quality of life of family caregivers of cancer patients in Singapore and globally.

INTRODUCTION: Family caregivers of cancer patients often suffer from impaired quality of life (QOL) due to stress arising from the responsibility of caregiving. Most research on such QOL impairments was conducted in Western populations. Thus, this exploratory study sought to (a) examine the QOL levels of family caregivers of cancer patients in an Asian population in Singapore, in relation to caregivers from other countries within and outside of Asia; and (b) investigate the association between sociodemographic factors and QOL impairments in family caregivers in Singapore. METHODS: A total of 258 family caregivers of cancer patients who were receiving outpatient treatment completed the Caregiver Quality of Life Index-Cancer (CQOLC) and a sociodemographic survey. We compared the published CQOLC total scores from Turkey, Iran, Taiwan, South Korea, the United Kingdom, the United States and Canada with the Singapore dataset and examined the demographic relationships. RESULTS: Caregivers in Singapore and Asia had lower CQOLC total scores than their Western counterparts. Caregivers who were male, of Chinese ethnicity, had parental relationships with their care recipient, or cared for advanced-stage cancer patients were found to have impaired QOL. CONCLUSION: The findings of this study highlight possible areas in which support can be provided for family caregivers of cancer patients, and underscore the need to reconcile cultural diversity, values, societal expectations and demographic characteristics in Singapore.

The prevalence and predictors of subsyndromal anxiety and depression in adult Asian cancer patients across the first year of diagnosis.

AIM: There is an increased prevalence of anxiety and depression in Asian patients diagnosed with cancers; these are known to interfere with treatment, treatment adherence and mortality. This study sought to investigate the prevalence and predictors of subsyndromal anxiety and depression in first-year Asian cancer patients. METHODS: A total of 206 patients newly diagnosed with cancer in Singapore completed the Hospital Anxiety and Depression Scale (HADS) at T1 (baseline; on average 2 months post-diagnosis), T2 (3 months post-baseline) and T3 (6 months post-baseline). Subsyndromal anxiety and depression were identified using locally validated cut-offs (HADS-A ≥5 and HADS-D ≥7). Adjusted odds ratios were calculated using baseline predictors. RESULTS: Across the three time points, 68-69% of participants were identified as having subsyndromal anxiety and close to 27-38% participants were identified as having subsyndromal depression. Multivariate logistic regressions revealed a lack of predictors for T1 subsyndromal anxiety and depression. Participants with late/metastatic stages of cancer were almost four times as likely to suffer from subsyndromal anxiety at T2. Single participants had a 75% lowered odds, but those living in three to four room public housing were close to four times as likely to suffer from subsyndromal depression at T2. Older patients and those who had undergone surgery were found to significantly suffer from subsyndromal depression at T3. CONCLUSION: The significant levels of depression and anxiety coupled with the lack of consistent predictors across the first year following cancer diagnosis further underscore the importance of careful assessment and clinician-vigilance in recognizing and identifying Asian patients who may express these emotional sequelae following the cancer diagnosis. A better understanding of patients' pathophysiological and psychological responses and individual strengths and coping skills are thus essential.
