Introduction: In some countries, family members are not involved in routine pediatric cancer psychosocial care although it is essential. This integrative review aims to determine the extent of research on family members of pediatric cancer patients in Turkey. Method: Four main keywords were used: parent/sibling/family, child/pediatric, cancer and psychosocial outcomes to search articles on PubMed, EKUAL, ULAKBIM, WOS databases (limited to 1997-2017). Among first 317 hits, 284 records were excluded. Of 33 eligible articles, 14 were excluded due to sample characteristics. Results: Research on psychosocial effects of pediatric cancer on family members is mostly descriptive and offers moderate-quality evidence. The reported psychosocial effects are (1) depression, anxiety, hopelessness, acceptance; (2) burden of care, quality of life, posttraumatic stress disorder; and (3) need for social support, information. Discussion: This study will contribute to the literature and help for the planning of protective psychosocial interventions for family members of children with cancer in Turkey.
