Frequency and Predictors of Sibling Psychological and Somatic Difficulties Following Pediatric Cancer Diagnosis
Bibliographic record
Abstract
Siblings of children with cancer encounter stressors and challenges that can lead to severe distress and a host of psychological difficulties. Factors including age, gender, and disease characteristics of the child with cancer are reported to influence sibling adjustment. The majority of research, however, is dated, inconsistent, and marred by methodological problems. Guided by the disability-stress-coping model, the study examined the: (a) frequency of sibling and parent reported symptoms of anxiety and depression, internalizing and externalizing behavior problems, and somatic problems, (b) influence of sibling, family, and disease factors on sibling adjustment, (c) moderating effects of age on the relationship between sibling factors and sibling adjustment, and (d) mediating effect of primary cognitive appraisal on the relationship between self-esteem and sibling adjustment.\nOne hundred and eight siblings (7-17 years; 51 males; 57 females) participated. Siblings completed the State-Trait Anxiety Inventory for Children and the Children’s Depression Inventory to provide measures of sibling reported symptoms of anxiety and depression. Parents completed the Child Behavior Checklist to provide measures of parent reported internalizing behavior problems, externalizing behavior problems, and somatic problems. The communication and intrapersonal thoughts and feelings subscales of the Sibling Perception Questionnaire, completed by siblings, were used to assess perceived social support and primary cognitive appraisal. Self-esteem was assessed with the global self-worth subscale of the Self Perception Profile for Children/Adolescents, completed by siblings. Hierarchical regression analyses were conducted to assess the direct and indirect effects of sibling, family, and disease factors on psychological outcomes.\nSiblings and parents reported higher incidents of clinically significant symptoms of anxiety, internalizing behavior problems, and somatic problems than expected in a normative population. Sibling age and gender, diagnosis of the child with cancer, social support, self-esteem, and primary cognitive appraisal were significantly associated with sibling and parent reported psychological adjustment measures. Age moderated the relationship between gender, social support, and primary cognitive appraisal and several adjustment outcomes. Lastly, primary cognitive appraisal partially mediated the relationship between self-esteem and sibling reported anxiety and depression symptoms. These findings highlight the need for sibling psychosocial interventions and provide direction for the development and implementation of such groups.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
