Psychological research in childhood cancer: the Children's Oncology Group perspective

Ethical concerns when recruiting children with cancer for research: Swedish healthcare professionals' perceptions and experiences

BACKGROUND

Research is crucial to improve treatment, survival and quality of life for children with cancer. However, recruitment of children for research raises ethical challenges. The aim of this study was to explore and describe ethical values and challenges related to the recruitment of children with cancer for research, from the perspectives and experiences of healthcare professionals in the Swedish context. Another aim was to explore their perceptions of research ethics competence in recruiting children for research.

METHODS

An explorative qualitative study using semi-structured interviews with key informants. Seven physicians and ten nurses were interviewed. Interviews were analysed using inductive qualitative content analysis.

RESULTS

The respondents' ethical challenges and values in recruitment mainly concerned establishing relationships and trust, meeting informational needs, acknowledging vulnerability, and balancing roles and interests. Ensuring ethical competence was raised as important, and interpersonal and communicative skills were highlighted.

CONCLUSION

This study provides empirical insight into recruitment of children with cancer, from the perspectives of healthcare professionals. It also contributes to the understanding of recruitment as a relational process, where aspects of vulnerability, trust and relationship building are important, alongside meeting informational needs. The results provide knowledge on the complexities raised by paediatric research and underpin the importance of building research ethics competence to ensure that the rights and interests of children with cancer are protected in research.

How Has the Occupational Performance and Participation Levels of Children with Cancer Changed during the COVID-19 Pandemic?

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.

Social Support in Parents of Children With Cancer: A Systematic Review

OBJECTIVES

Parents of children with cancer (PCCs) experience stress as they navigate managing their child's illness. Arguably, social support is critical to PCCs' well-being. This review examines the literature on social support in PCCs.

METHODS

Studies of social support in PCCs were collected from PsycINFO, CINHAL, and MEDLINE. Data were extracted from 37 studies published between January 2010 and May 2021 related to the conceptualization, measurement, and availability of social support in PCCs. Relationships between PCCs' social support, well-being, and unique parent and child factors were also synthesized. Risks of biases were assessed using domains of the Effective Public Health Practice Project.

RESULTS

Social support in PCCs is conceptualized as (a) perceived availability and satisfaction with social support and (b) social support seeking as a coping strategy. Parents of children with cancer report receiving as much or more support than typical adults, but PCCs engage in less social support seeking. Family and significant others are the most prevalent sources of support, and emotional support is the most received type of social support. Social support is positively related to well-being and negatively related to distress, anxiety, and posttraumatic stress. Findings related to social support differences based on parent and child unique factors were minimal and present opportunities for future research. The risk of bias was generally low, with caution that most studies cannot demonstrate directionality of findings due to cross-sectional study designs.

CONCLUSIONS

Given the consistent positive association between social support and well-being in PCCs, clinicians should assess and encourage social support for this vulnerable population.

Few guidelines offer recommendations on how to assess and manage anxiety and distress in children with cancer: a content analysis

PURPOSE

To (1) describe and compare, across all eligible guidelines, recommendations that address any aspect of clinical assessment or management of anxiety and distress experienced by children and adolescents undergoing cancer treatment or hematopoietic stem cell transplantation (HSCT), and (2) assess guideline characteristics that influence identified recommendations.

METHODS

We searched five databases for relevant guidelines and conducted a grey literature search. Guidelines had to refer to children 0-18 years old who were undergoing cancer treatment or HSCT, describe any aspect of clinical assessment or management of symptoms of anxiety and distress, and be publicly accessible and published in English on or after 2000.

RESULTS

We identified 118 guidelines on pediatric cancer of which 13 mentioned clinical assessment or management of anxiety and distress. Six contained ≥ 1 recommendation addressing assessments of symptoms of which only two recommended specific screening instruments. Ten contained ≥ 1 recommendation addressing interventions for symptoms, of which six described specific interventions such as distraction and medication. Psychologists and nurses were the most common panel members and three guideline panels included a patient advocate. Only two guidelines received overall quality ratings > 80.0%.

CONCLUSION

We identified no guidelines that were specific to clinical assessment or management of anxiety and distress among children and adolescents undergoing cancer treatment or HSCT, and thus, clinicians lack evidence-informed guidance on how to manage these specific symptoms. Future research should establish high-quality guidelines that offer recommendations specific to clinical assessment and management of anxiety and distress in pediatric oncology and HSCT.

Usability, Acceptability, Feasibility, and Effectiveness of a Gamified Mobile Health Intervention (Triumf) for Pediatric Patients: Qualitative Study

Background

Mental disorders are notably prevalent in children with chronic illnesses, whereas a lack of access to psychological support might lead to potential mental health problems or disruptions in treatment. Digitally delivered psychological interventions have shown promising results as a supportive treatment measure for improving health outcomes during chronic illness.

Objective

This study aimed to evaluate the usability, acceptability, and feasibility of providing psychological and treatment support in a clinical setting via a mobile game environment. In addition, the study aimed to evaluate the preliminary effectiveness of the mobile health game.

Methods

Patients aged 7 to 14 years with less than a year from their diagnosis were eligible to participate in the study. In total, 15 patients were invited to participate by their doctor. A total of 9 patients (age range: 7-12 years; mean age 9.1 years) completed the 60-day-long study in which the Triumf mobile health game was delivered as a digital intervention. In an engaging game environment, patients were offered psychological and treatment support, cognitive challenges, and disease-specific information. The fully digital intervention was followed by a qualitative interview conducted by a trained psychologist. The results of the interview were analyzed in conjunction with patient specific in-game qualitative data. Ethical approval was obtained to conduct the study.

Results

Patients positively perceived the game, resulting in high usability and acceptability evaluations. Participants unanimously described the game as easy to use and engaging in terms of gamified activities, while also providing beneficial and trustworthy information. Furthermore, the overall positive evaluation was emphasized by an observed tendency to carry on gaming post study culmination (67%, 10/15). Psychological support and mini games were the most often used components of the game, simultaneously the participants also highlighted the education module as one of the most preferred. On average, the patients sought and received psychological support or education on 66.6 occasions during the 60-day intervention. Participants spent the most time collecting items from the city environment (on average 15.6 days, SD 8.1), indicative of exploratory behavior, based on the quantitative in-game collected data. During the intervention period, we observed a statistically significant decrease in general health problems (P=.003) and saw a trend toward a decrease in depression and anxiety symptoms.

Conclusions

This study demonstrated that a game environment could be a promising medium for delivering comprehensive supportive care to pediatric patients with cancer alongside standard treatment, with potential application across a variety of chronic conditions. Importantly, the results indicate that the study protocol was feasible with modifications to randomized controlled trials, and the game could be considered applicable in a clinical context. By giving an empirical evaluation of delivering psychological support via the game environment, our work stands to inform future mobile health interventions.

Parents' Perspectives on Their Child's Social Experience in the Context of Childhood Chronic Illness: A Qualitative Study

PURPOSE

Many children suffer from a serious chronic illness. These children have greater risks of developing psychosocial difficulties, associated with school absenteeism and missed social opportunities. Through parents' perspectives, this study aimed to gain a holistic understanding of children's social experience in the context of chronic illness.

DESIGN AND METHODS

We conducted semi-structured interviews with parents of a child with a serious chronic illness exploring their child's school experience. Two researchers coded social experiences using an iterative process, involving regular team discussions. Theoretical thematic analysis and content analysis were both performed, using the social ecological model as a theoretical framework.

RESULTS

Forty-nine parents participated (43 mothers, 6 fathers; child mean age 11.51 years; 21 female children, 28 male children; 6 different chronic illness groups). According to parents, the main facilitators to the social experience of their children involved parents themselves, the school, social networks and peers, as they were all able to provide social support and opportunities for social development. However, peers were also a source of bullying and peer pressure, and sometimes lacked understanding and empathy.

CONCLUSIONS

As shown by the social ecological model, social functioning between chronically-ill children and their peers can be influenced by many factors. More specifically, parents have expressed their ability for promoting positive experiences between their children and their peers. Practice Implications Considering the complexity of social functioning, future research and interventions should provide holistic support for children with chronic illnesses.

The Need for Research Infrastructures: A Narrative Review of Large-Scale Research Infrastructures in Biobanking

BACKGROUND

Distributed Research Infrastructures are gaining political traction in Europe to facilitate scientific research. This development has gained particular momentum in the area of biobanking where cross-national attempts have been made toward harmonizing the biobanking standards across the European Union through the establishment of the organization BBMRI (BioBanking and Biomolecular Resources Research Infrastructure). BBMRI exists as separate national nodes across several European countries, although Sweden took on a pioneering role in its early stages. Thus, the Swedish node, BBMRI.se, was set up in 2009.

PURPOSE

To document publications addressing the current debate on large-scale distributed medical and/or biobank Research Infrastructures and identify the most pressing issues discussed by these articles through a narrative review.

METHODS

The Web of Science (WOS) and PubMed databases were searched to find prior studies of large-scale medical Research Infrastructures, with no limits set with regard to study design and/or time period. All identified articles published up until March 2016 were included in the initial review.

RESULTS

A total of 145 articles were retrieved from WOS and PubMed, though merely 17 ultimately made it past the final exclusion criteria. About two-thirds of the articles listed a first author affiliated to a European country. The articles most commonly discussed the need for developing and expanding the use of "infrastructures."

PRACTICAL IMPLICATIONS

The future of scientific research will call for a deeper and more widespread multidisciplinary collaboration. This will emphasize the need of research seeking to optimize the preconditions of securing sustainable scientific collaboration. Future investigators will thus need to understand the components and mechanisms of Research Infrastructures in addition to acquiring knowledge of how to build, manage, brand, and promote them as well.

Reflections on developing collaborative research in pediatric psychology: implications and future directions

OBJECTIVES

Collaborative research with pediatric colleagues has become increasingly important in the professional agenda of pediatric psychology, and there is a continuing need to articulate the challenges of such research. To address this need, this article describes types of collaborative research, reasons for collaboration, collaborative process, challenges, and strategies to facilitate collaborative research.

METHODS

Experiences and lessons learned over the course of a career in collaborative research are described.

RESULTS

Challenges in collaborative research can be overcome by effective strategies of engagement and communication. Useful methods of training researchers in collaborative research include modeling and supervised mentored experiences in research initiated by trainees.

CONCLUSION

Data are needed to identify the characteristics of successful collaborative research, strategies to promote effective research, and methods of training and career development.

Psychosocial services in the first 30 days after diagnosis: results of a web-based survey of Children's Oncology Group (COG) member institutions

BACKGROUND

This study examines what proportion of families of recently diagnosed pediatric cancer patients are offered recommended psychosocial services, and if that proportion is linked to size of institution or number of psychosocial staff.

PROCEDURES

A web-based survey was offered to all institutions belonging to the Children's Oncology Group (COG).

RESULTS

Respondents from 127/212 (=59.9%) COG institutions provided information about percentage of families offered specific services within the first 30 days after diagnosis, and barriers to providing such services, as well as information about other factors that might affect their ability to provide psychosocial care. All sites reported that ≥50% of families are offered 21 of the 27 services investigated in this study. Over half of respondents (n=290) indicated that inadequate funding for staff (72%) and families' time constraints (63%) were barriers to providing psychosocial care. There was a positive relationship between the total number of psychosocial staff and the number of new patients seen annually (Pearson correlation=0.3409, P-value < 0.0004), but not between the total number of psychosocial staff and specific services offered. Most sites do not use validated assessment tools or evidence-based psychosocial interventions.

CONCLUSIONS

While some version of most recommended psychosocial services are offered across COG institutions, evidence-based psychosocial services are offered at only 11% of sites. Advances in psychosocial outcomes in pediatric oncology could be accelerated by multi-site collaboration, use of standardized assessment tools, and evidence-based interventions.

Developing a Scale to Measure Parental Worry and Their Attitudes Toward Childhood Cancer After Successful Completion of Treatment

The purpose of this study is to develop and evaluate the psychometric characteristics of a scale designed to measure parents’ attitude toward childhood cancer after treatment has ended. In this study, the 2 theoretical frameworks (theory of attitude and theory of worry) were used as they related to the study. An attitude is an idea charged with negative or positive emotion, directed to a psychological object, such as cancer. A sample of 84 White, middle class, American parents (n = 49 mothers, n = 35 fathers) of 51 childhood cancer survivors, whose treatment ended between 1988 and 2005, was surveyed between November 2005 and February 2006. Two factors were extracted using principal component analysis with oblique rotation. Cronbach’s alpha reliability for Factor 1 was .91 and for Factor 2 was .76. This study suggests that most parents of cancer survivors tend to perseverate, ruminating on the idea that their child’s cancer will return; as a result, they remain in a heightened state of alertness and develop uncontrollable thoughts, or inconsolable worry, about the recurrence of the disease.

Happiness and time perspective as potential mediators of quality of life and depression in adolescent cancer

BACKGROUND

Given the increase in 5- and 10-year survival rates of children and adolescents diagnosed with cancer, current psycho-oncology literature is focusing on finding correlates and predictors to their positive psychosocial adjustment. The purpose of this study was to evaluate two potential mediators to adolescent cancer survivors' quality of life (QOL) and depressive symptomology.

PROCEDURE

Adolescent cancer survivors (N = 50; 50% males; mean diagnosis age, 13.7; mean age at study, 20.2) were surveyed, testing the mediation effects of their happiness (Subjective Happiness Scale) and past-negative time perspective (Zimbardo Time Perspective Inventory) on QOL (PedsQL 4.0) and depressive symptomology (CES-D). Independent variables included gender and treatment intensity.

RESULTS

Happiness significantly mediated the relationship between treatment intensity in both depressive symptomology (beta = -0.65, P < 0.05, CI = -2.46, -6.41) and QOL (beta = 0.54, P < 0.05, CI = 3.66, 9.01). A past-negative time perspective significantly mediated the relationship between gender and depressive symptomology (beta = 0.60, P < 0.05, CI = 3.34, 9.78). Survivors' gender was not associated with happiness and treatment intensity was not associated with time perspective.

CONCLUSIONS

Happiness may be a more direct predictor of QOL and depression than the intensity of treatment for cancer. Also, thinking negatively about one's past may be a more direct predictor of depressive symptomology than being female. Therefore, interventions that cultivate happiness and reframe time perspective may be effective ways to improve survivors' QOL and decrease depressive symptoms-regardless of gender and intensity of treatment protocol.

Intensity of CNS treatment for pediatric cancer: prediction of social outcomes in survivors

PURPOSE

To evaluate the association of central nervous system (CNS) treatment intensity and the social functioning of children who have completed treatment for leukemia, lymphoma, and solid tumors outside the CNS. Furthermore, we expected that these associations would be moderated by child age at diagnosis and gender.

METHOD

Peer, teacher, and self-report data were obtained for 82 cancer survivors (age 9-17 years) using classroom rating and nomination procedures that are widely used in research on social development. Information regarding cranial radiation therapy (CRT), intrathecal chemotherapy (ITC), and systemic methotrexate were obtained from medical records and used to create a composite index of CNS treatment intensity.

RESULTS

Higher scores on the index of CNS treatment intensity were associated with poorer peer acceptance, fewer friendships, greater social sensitivity-isolation, and diminished leadership-popularity based on peer-report. These associations were stronger for boys and children who were younger (<10 years old) at diagnosis. In contrast, CNS treatment intensity was only predictive of teacher-perceptions of aggressive-disruptive behavior and it was unrelated to social self-perceptions.

CONCLUSION

These results suggest that children who receive CRT and ITC are at risk for problematic peer relations, particularly if they are male or younger at diagnosis. Given the stability of poor peer relationships and documented linkages between peer problems and subsequent academic and psychiatric difficulties, clinical services should address these issues. Research is needed to identify mechanisms that account for these outcomes and provide direction for prevention and treatment efforts.

Socioeconomic impact of modern multidisciplinary management of retinoblastoma

OBJECTIVE

Our objective for this study was to examine the impact of the modern management of intraocular retinoblastoma on the patient and the family.

METHODS

This study comprises a retrospective, noncomparative case series of 25 consecutive patients with multifocal, intraocular retinoblastoma that was treated with primary systemic chemotherapy. Medical charts were reviewed, and the following data were extracted: patients' age and gender, laterality of disease, and Reese-Ellsworth classification of each eye as well as the number of central venous lines placed, cycles of chemotherapy received, outpatient appointments, examinations under anesthesia, focal therapies administered, computed tomography/MRI, radiation treatments, anesthetic procedures administered, and miles traveled.

RESULTS

Twenty patients with bilateral and 5 with unilateral intraocular retinoblastoma (median age: 9.3 months) had 895 outpatient appointments and underwent 698 examinations under anesthesia with 230 focal therapies, 347 days of radiotherapy, 226 computed tomography scans/MRIs, and 38 central venous line placements. A total of 1272 anesthetic procedures (median: 50) were performed with no major complication. In all, patients traveled 822312 miles (median: 22214 miles) to receive their care. The median follow-up was 82 months.

CONCLUSIONS

Successful retinoblastoma management requires close surveillance, aggressive consolidation, and numerous anesthetic procedures, all of which the patients and the families must endure. There is a significant impact on the patient, the family, and hospital resources.
