Objective: This study aimed to develop a Resilience Scale for Parents of Children with Cancer (RSP‐CC) designed specifically for parents of children with cancer and to evaluate its psychometric properties.Methods: Based on the Resilience Model for Families of Children with Cancer, items were created after an extensive literature review and evaluated through expert consultation and a pilot study. Psychometric evaluation was conducted with the parents of 601 children with cancer in the pediatric hematology oncology services of different hospitals in the Ankara and Kayseri provinces in Turkey.Results: A 4‐factor structure was illustrated by exploratory factor analysis and confirmed by confirmatory factor analysis, explaining 62.192% of the total variance. In the reliability analysis of the scale, Interclass correlation = 0.993 and Cronbach's alpha = 0.994 were found for the scale. Robust correlation coefficients were found between test‐retest, and the correlation between the two measurements was statistically significant (r = 0.990; p ˂ 0.001). As a result, the validity of a 24‐item scale structure consisting of 4 dimensions was validated.Conclusions: It may be said that the RSP‐CC meets the necessary criteria to examine the resilience in parents of children aged 0–18 with a cancer diagnosis, and its psychometric properties are reasonable sufficient.

This mixed-methods study examined the impact of childhood cancer on family functioning from a parental perspective. Parents of children on-treatment were included in the study. Quantitative data were collected from 246 parents, and multiple regression analyses were conducted to identify key predictors. Additionally, qualitative data were obtained through semi-structured interviews with 28 parents and analyzed using thematic analysis. Quantitative results indicated that higher perceived social support, parental resilience, and effective coping strategies were positively associated with family functioning, whereas a longer cancer trajectory and heavier caregiving burden had negative effects ( p < 0.05). Qualitative findings revealed that parents experienced significant emotional strain, evolving family roles, and challenges in balancing attention across family members. Supportive networks, empathic healthcare providers, and adaptive coping strategies may serve as important protective factors against the negative impact of a cancer diagnosis, which affects not only the diagnosed child but also the entire web of family relationships.

Primary malignant bone tumors are significant health concerns in children. These tumors, often accompanied by pain, fatigue, and reduced physical function, can lead to the development of kinesiophobia, a fear of movement that can further complicate rehabilitation. Although factors associated with kinesiophobia have been examined in various adult cancer populations, there is limited research on kinesiophobia and its predictors in children with bone tumors. This study aims to investigate the factors contributing to kinesiophobia in pediatric bone tumor patients. This prospective cross-sectional study was conducted in children with primary malignant bone tumors aged 8–17 years who actively on treatment. The Tampa Scale for Kinesiophobia (TSK) was used to assess fear of movement. Other assessments included the numerical rating scale (NRS) for pain, the PedsQL™ Multidimensional Fatigue Scale for fatigue, the Children Depression Rating Scale-Revised (CDRS-R) for depression, manual muscle testing, and the TUG Test for functionality. Logistic regression was performed to identify predictors of kinesiophobia, while chi-square tests examined the relationship between muscle strength and kinesiophobia levels. One hundred children with bone tumors an average age of 11.83 years participated in the study. The logistic regression model indicated that surgery status, pain levels, and fatigue were significant predictors of kinesiophobia, with an R 2 value of 0.870, explaining 87% of the variance in kinesiophobia levels. Children who had surgery and were in more pain and had higher levels of depression were more likely to exhibit kinesiophobia. Conclusion: This study highlights the multifactorial nature of kinesiophobia in children with malignant bone tumors, emphasizing the roles of surgical status, pain, and psychological factors. Integrating biopsychosocial assessments and approaches into routine care may be important to reduce kinesiophobia, improve rehabilitation outcomes, and increase overall well-being. What is Known: •  Kinesiophobia has been studied in adult cancer populations and has been associated with decreased physical  activity and poorer rehabilitation outcomes. What is New: •  This study demonstrates that surgery status, pain levels, and fatigue are significant predictors of kinesiophobia in children with malignant bone tumors and highlights that, in addition to various cancer-related symptoms, kinesiophobia can also be present in this population.

Background: Neurocognitive sequelae are among the most debilitating effects of cancer observed in children. Yet we know very little about the impact on neurocognitive functioning, especially cancer types that develop outside the central nervous system. This study aimed to assess and compare the cognitive functions (CoF) of children with bone tumours and lymphoma in the treatment process.Methods: The CoF of children with bone tumours (n = 44), lymphoma (n = 42) and their non‐cancer peers (n = 55) were assessed with Dynamic Occupational Therapy Assessment for Children. The CoF of children with cancer were compared with their non‐cancer peers. Then, children with bone tumours and lymphoma were compared in binary.Results: One‐hundred forty‐one children aged 6–12 years with a mean age of 9.4 (SD = 1.5) were included in this study. The orientation and visuomotor construction functions of children with bone tumours and orientation, praxis and visuomotor construction functions of children with lymphoma performed worse than their non‐cancer peers (pk < 0.001). While orientation, spatial perception, visuomotor construction and thinking operations functions of children with bone tumours and lymphoma were similar (pk > 0.016), praxis functions of children with lymphoma were found to be worse than children with bone tumours (pk < 0.016).Conclusions: Our findings show that children with bone tumours and lymphoma in the process of treatment are at risk for impairment of their CoF. The findings highlight the importance of assessing CoF in children with bone tumours and lymphoma and considering specific differences between groups. It is essential to assess CoF and develop early intervention plans in these children.

Aim: To examine how the occupational performance (OP) and participation levels of children with cancer changed during the COVID-19 pandemic. Methods: Sixty-seven children with cancer (aged 6–12 years) completed the Canadian Occupational Performance Measure by giving information about their OP and participation, and their parents completed the Child and Adolescent Scale of Participation via online interview techniques. Evaluations were repeated twice in April and September 2020 to determine the change in OP and participation levels of children with cancer due to the COVID-19. Results: OP of children with cancer decreased significantly (Z=-7.02, p < 0.001) during the pandemic period. The home participation of these children did not change significantly (Z=-0.98, p = 0.32) before and during the pandemic; and was limited in both periods. Community participation decreased significantly (Z=-4.84, p < 0.001) from limited level to very limited level. Conclusions: Findings emphasize the need to increase the levels of OP and participation levels of children with various types of cancer due to the ramifications of the COVID-19 pandemic.
