Psychosocial well-being of brain cancer patients and support persons: A mapping review of study types over time.

Introduction: This review examined the: (1) number of publications exploring psychosocial outcomes of adults with brain cancer and/or support persons between 1999 and 2019 and whether there has been a change in the type of research over time; and (2) proportion of intervention studies meeting Cochrane Effective Practice and Organisation of Care (EPOC) research design criteria.

Methods: Embase, The Cochrane Library, Medline and PsycINFO databases were electronically searched January 1999 to December 2019. Articles were examined against inclusion/exclusion criteria and coded into measurement, descriptive or intervention categories. Intervention studies were assessed against the EPOC design criteria.

Results: 220 eligible publications were identified. The number of total publications significantly increased by an average of 1 each year (95%CI = 0.7-1.3; p < 0.001). There was no significant change in the proportion of publications by study type across three time periods. Descriptive research represented the majority within each time period. Of the 17 intervention studies, only 7(41%) met EPOC design criteria.

Conclusions: Published literature on brain cancer psychosocial outcomes has increased significantly. However, descriptive research dominates research output. To increase high-level knowledge that can guide psychosocial care of people with brain cancer, there is a need to undertake methodologically rigorous intervention trials.
