Abstract
OBJECTIVE: To investigate, via systematic review and meta-analysis, caregiver sociodemographic and biopsychosocial factors associated with anxiety, depression, posttraumatic stress symptoms, and stress of caregivers in the pediatric chronic pain context. METHODS: EMBASE, Medline, and PsycINFO databases were searched from their inception to the search date (April 4, 2022). Studies were included if they examined caregivers of youth with chronic pain, were published in a peer-reviewed journal and assessed at least one quantitative association between relevant variables. Qualitative and intervention studies were excluded. A total of 3,052 articles were screened. Risk of bias was assessed using the JBI Checklist for analytical cross-sectional studies. Meta-analyses were conducted using robust variance estimation for associations reported in at least three studies, as well as a narrative synthesis of the evidence. RESULTS: Fourteen studies assessing 1,908 caregivers were included in this review. Meta-analytic results showed a positive pooled correlation coefficient between caregiver catastrophizing about their child's pain and caregiver anxiety (r = 0.51; 95% CI: 0.35-0.65; p<.01) and depression (r = 0.45; 95% CI: 0.29-0.58; p < .01). Self-blame and helplessness were related to increased caregiver anxiety (r = 0.55; 95% CI: 0.40-0.67; p<.01), but not depression. No significant relationship was found for pain-promoting behavior and anxiety or depression. The qualitative synthesis of all other eligible studies showed associations between relevant psychological burden variables and various caregiver factors, which were mainly psychosocial. CONCLUSION: Results should be interpreted with caution due to the small number of studies. Further research is needed to get a better understanding of these relationships and to examine the causal direction of effects.
