Feeling scared or worried self-report in children receiving cancer treatments using the Symptom Screening in Pediatrics Tool (SSPedi).

INTRODUCTION: The objectives of this study were to describe reports of bother for feeling scared or worried among children with cancer and pediatric hematopoietic stem cell transplant (HSCT) recipients, and to identify factors associated with it. METHODS: We included children receiving cancer treatments who were 8-18 years of age. Three patient types were enrolled: inpatients receiving active cancer treatment, outpatients receiving maintenance acute lymphoblastic leukemia chemotherapy, and outpatients in survivorship. Amount of bother due to feeling scared or worried yesterday or today was self-reported using the Symptom Screening in Pediatrics Tool (SSPedi) on a 0-4 scale. Risk factors were evaluated using logistic regression. RESULTS: Among the 502 children included, 225 (45.0%) reported any degree of bother (score ≥ 1) and 29 (5.8%) reported severe bother (score ≥ 3) for feeling scared or worried. In multiple regression evaluating any bother, boys were less likely to be bothered (odds ratio (OR) 0.60, 95% confidence interval (CI) 0.41-0.87) and inpatients receiving active cancer treatment were more likely to be bothered compared to outpatients in survivorship (OR 3.58, 95% CI 2.00-6.52). The only factor associated with being severely bothered by feeling scared or worried was clinic visit or admission due to fever (OR 4.57, 95% CI 1.24-13.60). DISCUSSION: We found 45% of children receiving cancer treatments reported being bothered by feeling scared or worried. Girls and inpatients receiving active treatment experienced more bother of any degree, while visiting the hospital due to fever was associated with being severely bothered. Future work should identify interventions to prevent or alleviate this symptom.

Longitudinal evaluation of Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK), a symptom screening and management application.

BACKGROUND: Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK) is a web application focused on improving symptom control. It enables pediatric cancer and hematopoietic stem cell transplant (HSCT) patients to self-report and track symptoms, and allows healthcare professionals to access guidelines for symptom management. Objective was to determine the feasibility of longitudinal collection of symptom data. METHODS: In this longitudinal, single-armed feasibility study, respondents were children 8-18 years of age with cancer or pediatric HSCT recipients. Participants completed symptom reporting daily for 5 days. Cognitive interviews were conducted on day 5. Quantitative evaluation included SPARK ease of use and understandability of SPARK reports. Qualitative feedback on facilitators and barriers to daily symptom screening was solicited. Feasibility was defined as ≥75% of participants completing symptom screening on at least 60% of on-study days during the five-day study. RESULTS: Among the 30 children enrolled, the median number of days SSPedi was completed at least once was 5 (range 3 to 5). Overall, 28/29 (96.6%) thought completing symptom screening using SPARK was easy or very easy. All participants understood SPARK symptom reports. Severe symptoms was the most common barrier to daily reporting while an alarm reminder system was the most commonly identified facilitator. CONCLUSIONS: Daily completion of symptom screening using SPARK over 5 days was feasible in children aged 8 to 18 years with cancer and pediatric HSCT recipients. SPARK is now appropriate for use in randomized trials to evaluate the effect of symptom screening and symptom feedback.

Development of mini-SSPedi for children 4-7 years of age receiving cancer treatments.

BACKGROUND: The Symptom Screening in Pediatrics Tool (SSPedi) is valid for assessing symptoms in children aged 8-18 years receiving cancer treatments. The objective was to develop a new self-report symptom screening tool for children receiving cancer treatments who are 4-7 years of age (mini-SSPedi), based on SSPedi. METHODS: Respondents were children with cancer or pediatric hematopoietic stem cell transplantation (HSCT) recipients who were 4-7 years of age. We included the same 15 symptoms contained in SSPedi. Using cognitive interviewing, we developed mini-SSPedi in three phases and made decisions based upon respondent understanding. First, we developed questionnaire structure regarding recall period, concept of bother and response option format. Second, we determined wording of each symptom. Third, we evaluated the entire mini-SSPedi instrument for understanding and ease of completion. RESULTS: We enrolled 100 participants in total and included 30, 40 and 30 in each of the three phases. Questionnaire structure was satisfactory with a recall period of "today" and a faces-based 3-point Likert scale. Bother was well-understood. Five symptoms required modification to achieve satisfactory understanding while the remaining 10 SSPedi symptoms did not require modification. Among the last 10 children enrolled, all understood each mini-SSPedi item and none thought mini-SSPedi was hard to complete. CONCLUSION: We developed a symptom screening tool for children with cancer and pediatric HSCT recipients between 4 and 7 years of age that is understandable and easy to complete. Future work will evaluate the psychometric properties of mini-SSPedi and develop an electronic version of the instrument.

Severely bothersome fatigue in children and adolescents with cancer and hematopoietic stem cell transplant recipients.

BACKGROUND: Objectives were to describe bothersome fatigue in children with cancer and hematopoietic stem cell (HSCT) recipients and to identify factors associated with severely bothersome fatigue. METHODS: We included children ages 8-18 years treated for cancer or HSCT recipients from three groups: [1] receiving active cancer treatment and admitted to hospital for at least 3 days, [2] attending outpatient clinic for acute lymphoblastic leukemia maintenance therapy, and [3] attending outpatient clinic following treatment completion. Fatigue was measured using the Symptom Screening in Pediatrics Tool (SSPedi); severely bothersome fatigue was defined as a lot or extremely bothersome fatigue (score of 3-4 on 0-4 scale). Factors associated with severely bothersome fatigue were examined using univariate and multiple logistic regression. RESULTS: Of 502 children included, 414 (82.5%) reported some degree of bothersome fatigue (scores 1-4), and 123 (24.5%) reported severely bothersome fatigue (score 3 or 4). In multiple regression analysis, factors significantly associated with severely bothersome fatigue were child age 11-14 and 15-18 years vs 8-10 years (odds ratio (OR) 2.11, 95% confidence interval (CI) 1.21-3.77 and OR 2.96, 95% CI 1.66-5.44), and inpatients receiving cancer treatment vs outpatients who had completed therapy (OR 3.85, 95% CI 2.17-7.27). CONCLUSIONS: We found that 82.5% of children with cancer or HSCT recipients reported bothersome fatigue and 24.5% of children reported severely bothersome fatigue. Risk factors for severely bothersome fatigue were older age and inpatients receiving active cancer treatment. Future work should evaluate systematic symptom screening in clinical practice and apply interventions to reduce fatigue.

Taste changes in children with cancer and hematopoietic stem cell transplant recipients.

BACKGROUND: Objectives were to describe bothersome self-reported changes in taste in pediatric oncology and hematopoietic stem cell (HSCT) patients and to identify patient and treatment-related factors associated with bothersome taste changes. METHODS: We prospectively enrolled children and adolescents with cancer or pediatric HSCT recipients 8-18 years of age from three groups: inpatients receiving cancer treatments; outpatients in maintenance therapy for acute lymphoblastic leukemia (ALL); and outpatients in survivorship. Bothersome changes in taste was self-reported using the Symptom Screening in Pediatrics Tool (SSPedi); nausea was self-reported using the Pediatric Nausea Assessment Tool (PeNAT). RESULTS: Among the 502 children included, 226 (45.0%) reported bothersome taste changes and 48 (9.6%) reported severely bothersome taste changes. In multiple regression, factors independently associated with severely bothersome taste changes were: inpatients receiving cancer treatments vs outpatients in survivorship (odds ratio (OR) 12.28, 95% confidence interval (CI) 2.50-222.27), ALL in maintenance vs outpatients in survivorship (OR 7.43, 95% CI 1.06-147.77), current nausea (OR 1.59, 95% CI 1.04-2.42), vomiting (OR 2.18, 95% CI 1.06-4.38), and first language not English (OR 2.09, 95% CI 0.97-4.28). CONCLUSIONS: We found that 45% of children with cancer and pediatric HSCT recipients reported bothersome changes in taste and these were severely bothersome in 9.6% of children. Inpatients receiving cancer treatment, those experiencing more nausea and vomiting and children whose first language was not English were at greater risk of severely bothersome changes in taste. Future work should evaluate systematic symptom screening in clinical practice and identify interventions focused on addressing bothersome taste changes.

Initial development of Supportive care Assessment, Prioritization and Recommendations for Kids (SPARK), a symptom screening and management application.

BACKGROUND: We developed Supportive care Prioritization, Assessment and Recommendations for Kids (SPARK), a web-based application designed to facilitate symptom screening by children receiving cancer treatments and access to supportive care clinical practice guidelines primarily by healthcare providers. The objective was to describe the initial development and evaluation of SPARK from the perspective of children. IMPLEMENTATION: Development and evaluation occurred in three phases: (1) low fidelity focused on functionality, (2) design focused on "look and feel" and (3) high fidelity confirmed functionality and design. Cognitive interviews were conducted with children receiving cancer treatments 8-18 years of age. Evaluation occurred after every five interviews and changes were guided by a Review Panel. Quantitative evaluation included SPARK ease of use and understandability of SPARK reports. RESULTS: The number of children included by phase were: low fidelity (n = 30), design (n = 30) and high fidelity (n = 30). Across phases, the median age was 13.2 (range 8.5 to 18.4) years. During low-fidelity and design phases, iterative refinements to SPARK improved website navigation, usability and likability from the perspective of children and established symptom report design. Among the last 10 children enrolled to high-fidelity testing, all (100%) understood how to complete symptom screening, access reports and interpret reports. Among these 10 respondents, all (100%) found SPARK easy to use and 9 (90%) found SPARK reports were easy to understand. CONCLUSIONS: SPARK is a web-based application which is usable and understandable, and it is now appropriate to use for research. Future efforts will focus on clinical implementation of SPARK.

Pre-Morbid Developmental Vulnerabilities in Children With Newly Diagnosed Acute Lymphoblastic Leukemia (ALL).

BACKGROUND: Not all children with acute lymphoblastic leukemia (ALL) were developing in a typical manner prior to diagnosis. Pre-existing developmental vulnerabilities (DV) may be related to long-term neuropsychological sequelae following ALL treatment, yet little is known about the prevalence or nature of prior DV in this population. PROCEDURE: Children with newly diagnosed ALL aged 2-18 years (n = 115) were screened for DV by asking parents about the child's prior developmental history and with the Developmental Profile-3 (DP-3). RESULTS: Twenty-six participants (23% of total sample) screened positive for prior DV, with one or more of the following: delayed early motor and/or language milestones that required intervention (n = 17), prior diagnosis of Down syndrome (n = 3), prior diagnosis of autism spectrum disorder (n = 1), prior diagnosis of attention-deficit/hyperactivity disorder and/or learning disability (n = 6), or prior neurological conditions (n = 5). CONCLUSIONS: A sizable proportion of children with newly diagnosed ALL have pre-morbid DV that could potentially make them more vulnerable to reduced educational opportunities during treatment and neurotoxic late effects following treatment. Identification of the subset of children with ALL and DV is essential to direct early interventions and to study their long-term outcomes.

Neuropsychological late effects of treatment for acute leukemia in children with Down syndrome.

BACKGROUND: Children with Down syndrome (DS) have an elevated risk of developing acute leukemia, but little is known about treatment-related neuropsychological morbidity because they are systematically excluded from research in this area. The current study investigated neuropsychological outcomes in children with DS treated for acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML) compared to children with DS with no history of cancer. PROCEDURE: Participants were 4 to 17 years of age at testing and were administered measures of intelligence, academic achievement, language, visual-motor and fine-motor skills, and adaptive function. Patients had been off treatment for at least 2 years. RESULTS: The AML group (N = 12) had significantly lower verbal intelligence and receptive vocabulary compared to controls (N = 21). By contrast, the ALL group (N = 14) performed significantly worse than controls on measures of verbal intelligence, spelling, receptive and expressive vocabulary, visual-motor skills, and adaptive function. CONCLUSIONS: Patients with DS treated for AML may have specific post-treatment morbidity in verbal function, whereas those treated for ALL have broader morbidity affecting multiple neuropsychological domains and overall adaptive function. We hypothesize that the broader impairment profile of ALL survivors may be related to a combination of the longer duration of central nervous system-directed treatment for ALL compared to AML and the concomitant limited access to intervention opportunities during active treatment.

Functional plasticity in childhood brain disorders: when, what, how, and whom to assess.

At every point in the lifespan, the brain balances malleable processes representing neural plasticity that promote change with homeostatic processes that promote stability. Whether a child develops typically or with brain injury, his or her neural and behavioral outcome is constructed through transactions between plastic and homeostatic processes and the environment. In clinical research with children in whom the developing brain has been malformed or injured, behavioral outcomes provide an index of the result of plasticity, homeostasis, and environmental transactions. When should we assess outcome in relation to age at brain insult, time since brain insult, and age of the child at testing? What should we measure? Functions involving reacting to the past and predicting the future, as well as social-affective skills, are important. How should we assess outcome? Information from performance variability, direct measures and informants, overt and covert measures, and laboratory and ecological measures should be considered. In whom are we assessing outcome? Assessment should be cognizant of individual differences in gene, socio-economic status (SES), parenting, nutrition, and interpersonal supports, which are moderators that interact with other factors influencing functional outcome.

Initial development of the Symptom Screening in Pediatrics Tool (SSPedi).

BACKGROUND: We previously identified published scales for symptom assessment in pediatric cancer patients. The objectives of this study were to identify if any of these scales were suitable for use or adaptation as a self-report symptom screening tool, and if not, to begin the process of creating a new tool. METHODS: A focus group of ten healthcare professionals with expertise in pediatric cancer symptom management and a patient advocate were convened. First, the group identified the optimal properties of a symptom screening tool for pediatric cancer patients. Next, the previously identified symptom assessment scales were evaluated against these properties. As none of the existing scales were adequate for symptom screening, a nominal group technique was used to identify the most important symptoms for inclusion in a new symptom screening tool. RESULTS: Optimal properties of a symptom screening tool included minimal respondent burden, inclusion of 15 items or less, and inclusion of the most burdensome symptoms. None of the previously identified scales were adequate because they lacked content validity and were too long or would be too hard for children to understand. Nominal group technique identified 15 items to be included; an initial draft was developed and named the Symptom Screening in Pediatrics (SSPedi) Tool. CONCLUSIONS: This study identified the lack of an appropriate symptom screening tool for use by pediatric cancer patients. A preliminary version of SSPedi was developed. Subsequent work will ensure that it is understandable by children and evaluate its psychometric properties.

Measuring what gets done: Using goal attainment scaling in a vocational counseling program for survivors of childhood cancer.

BACKGROUND: Childhood cancer survivors face education and employment challenges due to physical, cognitive, and psychosocial effects of the disease and treatments, with few established programs to assist them. The objectives of this study were to describe the implementation of Goal Attainment Scaling (GAS) to evaluate an educational and vocational counseling program established for survivors of childhood cancer, and analyze patterns of program engagement and client outcomes, stratified by demographic and diagnostic characteristics. METHODS: A population-based retrospective cohort study of childhood cancer survivors who were engaged with the Pediatric Oncology Group of Ontario's School and Work Transitions Program (SWTP) between January 2015 and December 2018 was utilized. Survivors were followed from SWTP engagement until May 30, 2019 to capture goal attainment. Individual goals were summarized across various demographic, disease, and treatment strata. RESULTS: In total, 470 childhood cancer survivors (median age = 17.9, 58% male) set 4,208 goals in the SWTP during the study period. The mean length of observation was 130.8 weeks (SD = 56.9). Overall, 68% of the goals were achieved. Eighty-three percent of the goals related to further education. Clients diagnosed with a solid tumor set the most goals on average, followed by those with central nervous system tumors and leukemia/lymphoma. CONCLUSIONS: The SWTP assists childhood cancer survivors in realizing their academic and vocational goals. Application of GAS in this setting is a feasible way to evaluate program outcomes. From the volume and breadth of the GAS goals set and achieved, the overall success of the SWTP appears strong.

Longitudinal evaluation of neurocognitive function after treatment for central nervous system germ cell tumors in childhood.

BACKGROUND: Central nervous system germ cell tumors (CNS GCT) are typically localized to midline structures of the brain, including the pineal and suprasellar/pituitary regions. Management of these tumors depends on underlying histology (germinoma or nongerminomatous germ cell tumor). Knowledge about neurocognitive outcome in these patients is limited. Longitudinal neurocognitive outcome in CNS GCT patients seen for neuropsychological evaluation at a single institution was explored. METHODS: Thirty-five patients were seen for neurocognitive evaluation after diagnosis and treatment for a CNS GCT. Mean age at diagnosis was 11.66 years. Tumor location was suprasellar in 12 patients, pineal in 9, bifocal in 10, multifocal in 3, and thalamic in 1. Standardized cognitive tests of intelligence, receptive language, visual-motor ability, memory, and academic achievement were administered. Longitudinal and cross-sectional analyses were conducted. RESULTS: Intelligence, academic functioning, and receptive vocabulary were not significantly compromised in most patients treated for CNS GCT. Working memory, information processing speed, and visual memory declined significantly over time in all patients. Patients with pineal tumors showed early and stable deficits, whereas patients with suprasellar and bifocal tumors showed more protracted declines from initial average functioning. Patients treated with ventricular versus craniospinal radiation displayed better outcome. CONCLUSIONS: Although general cognitive abilities appeared stable and intact after treatment for most children with CNS GCT, a significant decline over time in working memory, processing speed, and visual memory was evident. Tumor location appeared to be important in understanding the trajectory of stability and decline in CNS GCT patients, as did radiation field.

Long-term neurocognitive outcomes in young adult survivors of childhood acute lymphoblastic leukemia.

Five-year survival rates of childhood acute lymphoblastic leukemia (ALL) exceed 80% due to central nervous system-directed treatment including cranial radiation (CRT) and chemotherapy. However, these treatments are associated with neurocognitive compromise, the extent of which is correlated with higher dose and younger age at treatment. The aims of this study were to explore long-term neurocognitive outcomes in adult survivors of childhood ALL, and to identify measures sensitive to neurotoxicity in long-term survivors. We examined 24 adults who received 18 Gy CRT and chemotherapy for treatment of ALL between ages 2 and 15 years (median, 5.5). Time since diagnosis ranged from 6 to 26 years (median, 16.6). Younger age at diagnosis and longer time since diagnosis were associated with lower scores on a computerized battery that requires speed and accuracy across a number of domains (MicroCog), and other standardized neurocognitive tests. When compared with population norms, MicroCog indices were below average in survivors diagnosed with ALL before age 5, but only the reasoning/calculation index was below average in survivors diagnosed with ALL after age 5. In contrast, intelligence quotient (IQ) scores were average. In addition to confirming earlier studies showing that younger children are more vulnerable to treatment-related neurotoxicity, here we show that deficits exist many years post treatment even with a relatively lower dose of CRT, and that these deficits are especially evident on tasks involving rapid processing of information.

American Academy of Clinical Neuropsychology consensus conference statement on uniform labeling of performance test scores.

Objectives: Descriptive labels of performance test scores are a critical component of communicating outcomes of neuropsychological and psychological evaluations. Yet, no universally accepted system exists for assigning qualitative descriptors to scores in specific ranges. In addition, the definition and use of the term "impairment" lacks specificity and consensus. Consequently, test score labels and the denotation of impairment are inconsistently applied by clinicians, creating confusion among consumers of neuropsychological services, including referral sources, trainees, colleagues, and the judicial system. To reduce this confusion, experts in clinical and forensic neuropsychological and psychological assessment convened in a consensus conference at the 2018 Annual Meeting of the American Academy of Clinical Neuropsychology (AACN). The goals of the consensus conference were to recommend (1) a system of qualitative labels to describe results from performance-based tests with normal and non-normal distributions and (2) a definition of impairment and its application in individual case determinations. Results: The goals of the consensus conference were met resulting in specific recommendations for the application of uniform labels for performance tests and for the definition of impairment, which are described in this paper. In addition, included in this consensus statement is a description of the conference process and the rationales for these recommendations. Conclusions/Importance: This consensus conference is the first formal attempt by the professional neuropsychological community to make recommendations for uniform performance test score labels and to advance a consistent definition of impairment. Using uniform descriptors and terms will reduce confusion and enhance report comprehensibility by the consumers of our reports as well as our trainees and colleagues.

Quantitative MRI outcomes in child and adolescent leukemia survivors: Evidence for global alterations in gray and white matter.

INTRODUCTION: Cure rates for pediatric acute lymphoblastic leukemia (ALL) have reached an all-time high (>90%); however, neurocognitive difficulties continue to affect quality of life in at least a subset of survivors. There are relatively few quantitative neuroimaging studies in child and adolescent ALL survivors treated with chemotherapy only. Use of different outcome measures or limited sample sizes restrict our ability to make inferences about patterns of brain development following chemotherapy treatment. In this study, we used magnetic resonance imaging (MRI) to evaluate brain outcomes in ALL survivors, comparing against a group of typically developing, cancer free peers. MATERIALS AND METHODS: Participants included 71 ALL survivors, on average 8 years after diagnosis and 8-18 years of age, and 83 typically developing controls. Anatomical MRI was performed to evaluate brain structure; diffusion and magnetization transfer MRI were used to examine brain tissue microstructure. RESULTS: Successful MRI scans were acquired in 67 survivors (94%) and 82 controls (99%). Structurally, ALL survivors exhibited widespread reductions in brain volume, with 6% less white matter and 5% less gray matter than controls (p = 0.003 and 0.0006 respectively). Much of the brain appeared affected - 71 of 90 evaluated structures showed smaller volume - with the most notable exception being the occipital lobe, where no significant differences were observed. Average full-scale IQ in the survivor and control groups were 95 (CI 92-99) and 110 (CI 107-113), respectively. Using data from the NIH Pediatric MRI Data Repository, we evaluated the extent to which elevated IQ in the control group might affect the structural differences observed. We estimated that two thirds of the observed brain differences were attributable to ALL and its treatment. In addition to the structural changes, survivors showed, on average, globally lower white matter fractional anisotropy (-3%) and higher radial diffusivity (+5%) (p < 10-6), but no differences in magnetization transfer ratio. CONCLUSIONS: Neuroanatomical alterations in late childhood and adolescent ALL survivors treated with chemotherapy-only protocols are widespread, with white matter being somewhat more affected than gray matter. These MRI results indicate brain development is altered in ALL survivors and highlight the need to examine how these alterations emerge.

Evaluation of the electronic self-report Symptom Screening in Pediatrics Tool (SSPedi).

OBJECTIVE: We previously developed the paper-based Symptom Screening in Pediatrics Tool (SSPedi) designed for paediatric cancer symptom screening. Objectives were to evaluate and refine the electronic mobile application (app) of SSPedi using the opinions of children with cancer. METHODS: Participants were children 8-18 years of age with cancer. Participants completed electronic SSPedi on their own and then responded to semistructured questions to determine whether they found electronic SSPedi easy or difficult to complete and understand, understood and liked the app features (audio and animation), and understood previously difficult to understand concepts with the introduction of a help menu. After each group of 10 children, responses were reviewed to determine whether modifications were required. RESULTS: 20 children evaluated electronic SSPedi. None found electronic SSPedi difficult to complete or understand. All children understood the app features and each of the 4 more difficult to understand concepts after using the help menu. 19 of 20 children thought the app was a good way to communicate with doctors and nurses. CONCLUSIONS: We finalised an electronic version of SSPedi that is easy to use and understand with features specifically designed to facilitate child self-report. Future work will evaluate the psychometric properties of electronic SSPedi.

Validation of the Symptom Screening in Pediatrics Tool in Children Receiving Cancer Treatments.

Background: The objective was to evaluate the reliability and validity of the self-report Symptom Screening in Pediatrics Tool (SSPedi) from the perspective of children with cancer and pediatric hematopoietic stem cell transplant (HSCT) recipients. Methods: In this multicenter study, respondents were children age eight to 18 years who had cancer or had received HSCT, and their parents. Two different child respondent populations were targeted. More symptomatic respondents were receiving active treatment for cancer, admitted to the hospital, and expected to be in the hospital three days later. Less symptomatic respondents were in maintenance therapy for acute lymphoblastic leukemia or had completed cancer therapy. Children completed SSPedi and then responded to validated self-report measures of mucositis, nausea, pain, and global quality of life. Children in the more symptomatic group repeated SSPedi and a global symptom change scale three days later. Parent proxy-report was optional. Reliability was evaluated using intraclass correlations while convergent validity was evaluated using Spearman correlations. Results: Of 502 children enrolled, 302 were in the more symptomatic group and 200 were in the less symptomatic group. Intraclass correlation coefficients were 0.88 (95% confidence interval [CI] = 0.82 to 0.92) for test-retest reliability and 0.76 (95% CI = 0.71 to 0.80) for inter-rater reliability. The mean difference in SSPedi scores between more and less symptomatic groups was 7.8 (95% CI = 6.4 to 9.2). SSPedi was responsive to change in global symptoms. All hypothesized relationships among measures were observed. Conclusions: SSPedi is a self-report symptom bother tool for children with cancer and HSCT recipients that is reliable, valid, and responsive to change. SSPedi can be used for clinical and research purposes. Future work should focus on integration into care delivery.

Describing symptoms using the Symptom Screening in Pediatrics Tool in hospitalized children with cancer and hematopoietic stem cell transplant recipients.

Objectives were to describe any bothersome symptom and severely bothersome symptoms in inpatient children with cancer and hematopoietic stem cell transplant (HSCT) recipients. We included children 8-18 years of age with cancer or HSCT recipients who were receiving active treatment for cancer, admitted to hospital, and expected to be in hospital 3 days later. We administered the self-report Symptom Screening in Pediatrics Tool (SSPedi). We described those who identified any degree of symptom bother (at least "a little") and those who rated the degree of bother as severe ("a lot" or "extremely"). Factors associated with severe symptoms and total SSPedi scores were examined using multiple logistic and linear regression. Among the 302 patients, 298 (98.7%) reported having any bothersome symptom and 181 (59.9%) had at least one severely bothersome symptom. In multiple regression, older children were significantly more likely to have at least one severely bothersome symptom (15-18 and 11-14 years vs. 8-10 years; P = 0.008) and to have higher total SSPedi scores (P = 0.0003). Those with relapsed disease were more likely to have at least one severely bothersome symptom (odds ratio 2.1, 95% confidence interval 1.1-4.3; P = 0.037) and HSCT recipients were more likely to have higher symptom scores (ß = 3.48, standard error = 1.6; P = 0.030). Almost all children receiving cancer therapies experience bothersome symptoms and 60% have at least one severely bothersome symptom. Older children experienced more severely bothersome symptoms and higher symptom scores. Future studies should follow children longitudinally to better understand the symptom trajectory and should institute interventions to manage symptoms.

Validation of the Proxy Version of Symptom Screening in Pediatrics Tool in Children Receiving Cancer Treatments.

OBJECTIVES: Primary objectives were to evaluate the interrater reliability and validity of proxy-report Symptom Screening in Pediatrics Tool (SSPedi) in children with cancer and pediatric hematopoietic stem cell transplant (HSCT) recipients. Secondary objective was to describe the interrater reliability of each SSPedi item. METHODS: Respondents were children aged eight to 18 years with cancer or HSCT recipients, and their parents or guardians. We enrolled two pediatric respondent groups. The more symptomatic group was receiving active treatment for cancer, admitted to hospital, and expected to be in a hospital three days later. The less symptomatic group either was in maintenance therapy for acute lymphoblastic leukemia or had completed cancer treatments. Convergent validity was evaluated by comparing proxy-reported mucositis, nausea and vomiting, pain, and total SSPedi scores, with child self-reported validated scales, and we hypothesized fair correlations. Discriminant validity was evaluated by comparing proxy-reported total SSPedi scores between groups. Interrater reliability of each SSPedi item was evaluated. RESULTS: Four hundred thirty-nine child and parent or guardian pairs were recruited. Mean difference in proxy-reported SSPedi scores between the more and less symptomatic groups was 8.2, 95% CI 6.6-9.8. All hypothesized relationships among measures were observed. Intraclass correlation coefficients for SSPedi items ranged from 0.34 (problems with thinking) to 0.80 (diarrhea). CONCLUSION: Proxy-report SSPedi is reliable and valid in children aged 8 years to 18 years with cancer and HSCT recipients. Future work should support proxy-reported symptom assessment in clinical settings where children are not able to self-report or communicate bothersome symptoms.
