Abstract
Objective: Individuals affected by cancer have an elevated risk of experiencing suicidal crises. Aligning established suicide theories with social-cognitive theories, perceived control and related constructs emerge as potential protective factors for suicidal thoughts and behaviors in cancer patients. As perceived control is potentially modifiable, it holds great potential for prevention and intervention efforts. We aimed to comprehensively synthesize the evidence on perceived control and its link with suicidal thoughts and behaviors in cancer patients.
Methods: The search term and procedures were registered in PROSPERO (CRD42023391048). We systematically searched the databases PubMed/MEDLINE, CINAHL, PsycInfo, Web-of-Science Core Collection, Cochrane Library, adding a grey literature search. In addition to the narrative review, pooled effect sizes, moderation and subgroup analysis were calculated.
Results: The systematic search yielded 1986 original reports of which 36 were included in the systematic review and 25 in the meta-analysis. Demoralization, help-/hopelessness, and self-efficacy were the most commonly studied facets of control, showing a relatively large, pooled correlation with suicidal ideation overall (r = 0.45, [95% CI = 0.38-0.52], Q = 346.15, p < 0.01, I2 = 91.2%) and across operationalisations (demoralisation: r = 52; hopelessness: r = 45; self-efficacy: r = 0.40). Moderation analyses revealed no effect of cancer stages; but more directly cancer-associated variables (demoralisation, hopelessness) were more closely related to suicidal ideation (QM = 5.40, p = 0.02) than general self-efficacy.
Conclusion: The findings underscore the pivotal role of perceived control in shaping severe distress in cancer patients. More studies are needed examining perceived control in a narrower sense.
期刊介绍：
Psycho-Oncology is concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process. Psycho-oncology is an area of multi-disciplinary interest and has boundaries with the major specialities in oncology: the clinical disciplines (surgery, medicine, pediatrics, radiotherapy), epidemiology, immunology, endocrinology, biology, pathology, bioethics, palliative care, rehabilitation medicine, clinical trials research and decision making, as well as psychiatry and psychology.
This international journal is published twelve times a year and will consider contributions to research of clinical and theoretical interest. Topics covered are wide-ranging and relate to the psychosocial aspects of cancer and AIDS-related tumors, including: epidemiology, quality of life, palliative and supportive care, psychiatry, psychology, sociology, social work, nursing and educational issues.
Special reviews are offered from time to time. There is a section reviewing recently published books. A society news section is available for the dissemination of information relating to meetings, conferences and other society-related topics. Summary proceedings of important national and international symposia falling within the aims of the journal are presented.
