A systematic review of psycho-oncology research in Chinese populations : emerging trends

Abstract

The burden of cancer in China is increasing with future psycho-oncological interventions crucial. A systematic review of psycho-oncology research in China was undertaken to assess quantity, design and target trends over time. Medline, PsycINFO, CINAHL, ProQuest, Web of Science (1999–November Week 4, 2012) were searched. Inclusion criteria were: included cancer patients and/or partners or caregivers from resident Chinese populations (either at least 80% of participants are from China, Hong Kong or Taiwan); assessed psychological adjustment relating to cancer and published in English after 1 January 1999 and prior to 30 November 2012. In all, 208 articles met inclusion criteria. Of these: 52 were cross-sectional descriptive quantitative; 30 were cross-sectional descriptive qualitative; 27 were prospective descriptive quantitative; 2 were prospective descriptive qualitative; 18 assessed interventions; 79 presented instrument validation. Publications increased eightfold from 1999 to 2012. Most studies included patients (n = 195) with 11 articles focusing on caregivers and two on patient–caregiver dyads. The most common cancer studied was breast cancer. The psycho-oncology research effort in China is dramatically increasing. A focus on culturally relevant approaches to underpin the evaluation of empirically derived interventions is warranted; as is direction of efforts to other cancers such as lung and prostate.
