Background/objective: The use of patient-reported outcomes (PRO) is increasing in pediatric clinical practice and research, including in clinical trials. Treatment teams are now able to discern differences in symptom and function reports between children with cancer and their family caregivers. Few studies, however, have quantified such differences., Design/methods: Children and caregivers were matched to create a dyad sample, and child/caregiver agreement of responses to the Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric symptom and function measures were examined using the established minimally important difference (MID) value (three points) derived from these measures. Latent class analysis (LCA) was then used to analyze the status/patterns of response agreement., Results: A total of 430 dyadic cases (dyads) were used for LCA modeling. Three classes of child-caregiver concordance resulted: (a) Agreement-caregiver and child within one MID (200 dyads); (b) Disagreement-caregiver underestimating symptoms (47 dyads with caregiver scores more than 1 MID lower than the child scores); and (c) Disagreement-caregiver overestimating symptoms (183 dyads with caregiver scores more than 1 MID higher than child scores)., Conclusion: As PRO use increases in pediatric oncology, clinician identification of child/caregiver differences on symptom and function reports will help to distinguish family perceptions of cancer treatment impact. The treatment goal, in addition to mitigating symptom and function treatment-related burdens for the child and caregiver, may now also be to discern the direction and clinical meaning of the difference within the child-parent dyad., (© 2023 Wiley Periodicals LLC.

Background: Some children and adolescents receiving chemotherapy experience few symptom-related adverse events, whereas others experience multiple adverse events. If oncology nurses could identify patients likely to have pronounced chemotherapy-related adverse events, tailored supportive care could be matched to these patients' symptom burdens., Objective: The aim of this study was to identify symptom profiles in children and adolescents before and after chemotherapy, and the sociodemographic and psychological factors associated with profile classification and change., Methods: Participants ranging from 7 to 18 years (n = 436) completed 6 Patient-Reported Outcomes Measurement Information System pediatric symptom measures within 72 hours preceding (T1) and 1 to 2 weeks after (T2) chemotherapy. Profile membership and change were determined by latent profile/latent transition analyses. Associations with profiles and profile transitions were examined using multinomial logit models and logistic regression., Results: Three symptom suffering profiles were identified at T1 and T2: high, medium, and low. The high symptom suffering profile included the fewest participants (T1, n = 70; T2, n = 55); the low symptom suffering profile included the most participants (T1, n = 200; T2, n = 207). Of the participants, 57% remained in the same profile from T1 to T2. Psychological stress was significantly associated with T1 and T2 profile classifications and profile transition; age was associated with profile classification at T1., Conclusion: Three symptom suffering profiles existed in a sample of pediatric patients undergoing chemotherapy, indicating that children and adolescents have differing cancer treatment experiences., Implications for Practice: Oncology nurses could screen pediatric oncology patients for their symptom suffering profile membership and subsequently prioritize care efforts for those with a high suffering profile., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

Importance: The effect of pediatric advance care planning (pACP) on the sustainability of end-of-life treatment preference congruence between adolescents with cancer and their families has not been examined., Objective: To evaluate the longitudinal efficacy of the Family-Centered Advance Care Planning for Teens with Cancer (FACE-TC) intervention to sustain adolescent-family congruence about end-of-life treatment preferences., Design, Setting, and Participants: This multisite, assessor-blinded, randomized clinical trial enrolled adolescents with cancer (aged 14-21 years) and their family members from 4 pediatric hospitals between July 16, 2016, and April 30, 2019. Participants were randomized 2:1 to FACE-TC (intervention group) or treatment as usual (control group) and underwent 5 follow-up visits over an 18-month postintervention period. Intention-to-treat analyses were conducted from March 9, 2021, to April 14, 2022., Exposures: Adolescent-family dyads randomized to the FACE-TC group received 3 weekly 60-minute sessions consisting of the discussion and/or completion of the Lyon Family-Centered Advance Care Planning Survey (session 1), Respecting Choices Next Steps pACP conversation (session 2), and Five Wishes advance directive (session 3). Dyads in the control group received treatment as usual. Both groups received pACP information., Main Outcomes and Measures: Congruence was measured by completion of the Statement of Treatment Preferences (a document that discusses 4 hypothetical clinical situations and treatment choices for each scenario: continue all treatments, stop all efforts to keep me alive, or unsure) after session 2 (time 1) and at 3 months (time 2), 6 months (time 3), 12 months (time 4), and 18 months (time 5) after intervention. The influence of FACE-TC on the trajectory of congruence over time was measured by longitudinal latent class analysis., Results: A total of 252 participants (126 adolescent-family dyads) were randomized. Adolescents (mean [SD] age, 17 [1.9] years) and family members (mean [SD] age, 46 [8.3] years) were predominantly female (72 [57%] and 104 [83%]) and White individuals (100 [79%] and 103 [82%]). There was an 83% (104 of 126) retention at the 18-month assessment. Two latent classes of congruence over time were identified: high-congruence latent class (69 of 116 [60%]) and low-congruence latent class (47 of 116 [41%]). The dyads in the FACE-TC group had a 3-fold odds of being in the high-congruence latent class (odds ratio [OR], 3.22; 95% CI, 1.09-9.57) compared with the control group. Statistically significant differences existed at 12 months (β [SE] = 1.17 [0.55]; P = .03]) but not at 18 months (OR, 2.08; 95% CI, 0.92-4.69). In the high-congruence latent class, good agreement (agreement on 2 or 3 of 4 situations) increased over 12 months. White adolescents and families had significantly greater odds of congruence than a small population of American Indian or Alaska Native, Asian, Black or African American, Hispanic or Latino, or multiracial adolescents and families (OR, 3.97; 95% CI, 1.07-14.69)., Conclusions and Relevance: Results of this trial showed that, for those who received the FACE-TC intervention, the families' knowledge of their adolescents' end-of-life treatment preferences was sustained for 1 year, suggesting yearly follow-up sessions. Race and ethnicity-based differences in the sustainability of this knowledge reflect a difference in the effect of the intervention and require further study., Trial Registration: ClinicalTrials.gov Identifier: NCT02693665.

Background: Collecting symptom, function, and adverse event (AE) data directly from children and adolescents undergoing cancer care is more comprehensive and accurate than relying solely on their caregivers or clinicians for their interpretations. We developed the pediatric patient-reported outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) measurement system with input from children, parents, and clinicians. Here, we report how we determined the recommended Ped-PRO-CTCAE item scoring approach., Methods: Data from 271 patients were analyzed using three scoring approaches: (a) at the AE attribute (frequency, severity, interference) using ordinal and dichotomous measures; (b) a weighted composite AE item score by AE attribute (0.5 - frequency; 1.0 - severity; 1.5 - interference); and (c) overall number of AEs endorsed. Associations of each AE attribute, AE item score, and overall AE score with the Patient-Reported Outcome Measurement Information System (PROMIS) Pediatric measures were examined. The ability of the overall Ped-PRO-CTCAE AE score to identify patients with PROMIS symptom T-scores worse than reference population scores was assessed. Clinician preference for score information display was elicited through interviews with five pediatric oncology clinical trialists., Results: The diverse scoring approaches yielded similar outcomes, including positive correlations of the Ped-PRO-CTCAE attributes, AE item score, and the overall AEs score with the PROMIS Pediatric measures. Clinicians preferred the most granular display of scoring information (actual score reported by the child and corresponding descriptive term)., Conclusions: Although three scoring approaches yielded similar results, we recommend the AE attribute level of one score per Ped-PRO-CTCAE AE attribute for its simplicity of use in care and research., (© 2021 Wiley Periodicals LLC.)

Background and Objectives: There is a gap in family knowledge of their adolescents' end-of-life (EOL) treatment preferences. We tested the efficacy of Family Centered Advance Care Planning for Teens with Cancer (FACE-TC) pediatric advance care planning (to increase congruence in EOL treatment preferences., Methods: Adolescents with cancer/family dyads were randomized into a clinical trial from July 2016 to April 2019 at a 2:1 ratio: intervention (n = 83); control (n = 43) to either 3 weekly sessions of FACE-TC (Lyon Advance Care Planning Survey; Next Steps: Respecting Choices Interview; Five Wishes, advance directive) or treatment as usual (TAU). Statement of Treatment Preferences measured congruence., Results: Adolescents' (n = 126) mean age was 16.9 years; 57% were female and 79% were White. FACE-TC dyads had greater overall agreement than TAU: high 34% vs 2%, moderate 52% vs 45%, low 14% vs 52%, and P < .0001. Significantly greater odds of congruence were found for FACE-TC dyads than TAU for 3 of 4 disease-specific scenarios: for example, "a long hospitalization with low chance of survival," 78% (57 of 73) vs 45% (19 of 42); odds ratio, 4.31 (95% confidence interval, 1.89-9.82). FACE-TC families were more likely to agree to stop some treatments. Intervention adolescents, 67% (48 of 73), wanted their families to do what is best at the time, whereas fewer TAU adolescents, 43% (18 of 42), gave families this leeway (P = .01)., Conclusions: High-quality pediatric advance care planning enabled families to know their adolescents' EOL treatment preferences., (Copyright © 2022 by the American Academy of Pediatrics.)

Background: Fatigue, pain, and anxiety, symptoms commonly experienced by children with cancer, may predict pediatric symptom suffering profile membership that is amenable to treatment., Methods: Three latent profiles (Low, Medium, and High symptom suffering) from 436 pediatric patients undergoing cancer care were assessed for association with three single-item symptoms and socio-demographic variables., Results: Pediatric-PRO-CTCAE fatigue, pain, and anxiety severity scores at baseline were highly and significantly associated with the Medium and High Suffering profiles comprised of PROMIS pediatric symptom and function measures. The likelihood of membership in the Medium Suffering group was 11.37 times higher for patients who experienced fatigue severity than those with did not, while experience of pain severity increased the likelihood of the child's membership in the Medium Suffering profile by 2.59 times and anxiety by 3.67 times. The severity of fatigue increased the likelihood of presence in the High Suffering group by 2.99 times while pain severity increased the likelihood of the child's membership in the High Suffering profile by 6.36 times and anxiety by 16.75 times. Controlling for experience of symptom severity, older patients were more likely to be in the Higher or Medium Suffering profile than in the Low Suffering profile; no other socio-demographic or clinical variables had a significant effect on the latent profile classification., Conclusion: Clinician knowledge of the strong association between fatigue, pain, and anxiety severity and suffering profiles may help focus supportive care to improve the cancer experience for children most at risk from time of diagnosis through treatment., (© 2021.

Importance: The variability in individual symptom and adverse event reporting between pediatric patient-reports and proxy-reports is widely reported. However, the question of whether symptom profiles based on reports from children with cancer and their caregivers are similar or disparate have not yet been studied., Objective: To compare proxy symptom reports with patient self-reports to assess alignment., Design, Setting, and Participants: A multicenter cohort study was conducted from October 2016 to December 2018 from data collected at 9 pediatric cancer centers. Participants were a convenience sample of family caregivers or proxies of children aged 7 to 18 years who had received disease-directed oncology treatment in the form of chemotherapy for at least 1 month. Data were analyzed identifying clusters of individuals (ie, latent profiles) based on various responses (ie, indicators) in August 2021., Exposures: The children of proxy participants received upfront chemotherapy. Children and proxies completed Patient-Reported Outcomes Measurement Information System (PROMIS) surveys at 2 time points: within 72 hours preceding treatment initiation and following the course of chemotherapy., Main Outcomes and Measures: The latent profile analysis methods were applied to caregiver-proxy reports of PROMIS Pediatric symptom and function measures (anxiety, depressive symptoms, pain interference, fatigue, psychological stress, and physical function-mobility). The instrument categorized respondents as high symptom suffering, medium symptom suffering, and low symptom suffering (hereafter, high, medium, and low symptom groups, respectively)., Results: Of 580 approached proxies, 431 (368 [85.00%] were female) identified as legal guardians of children aged 7 to 18 years with a first cancer diagnosis (mean [SD] age, 13.03 [3.40] years; 235 [54.65%] were male). Proxy reports of children's experiences based on the 5 proxy PROMIS measures comprised 3 distinct symptom profiles. The most common proxy assessments of children's experiences were the moderate symptom groups (45.7% [197 of 431]) and the low symptom groups profiles (40.1% [173 of 431]). A high symptom groups profile emerged which represented 14.2% (61 of 431) of proxy assessments. The number of profiles and observed distribution of profile membership was similar between child and proxy reports. Proxy reports of individual symptoms generally recorded higher scores than child reports; however, no significant difference was observed between proxies and child profile model results for the PROMIS measures., Conclusions and Relevance: Results of this cohort study suggest that, at the level of symptom severity profile, proxy caregiver reports may approximate the children's reports and may serve as a guide to care when the child is not able to self-report.

Background: To determine if the intersectionality of gender and poverty is associated with health disparities among adolescents with cancer. We hypothesized unobserved latent classes of patients exist with respect to cancer-related symptoms; and class classification varies by gender-poverty combinations., Procedure: Cross-sectional data were collected among adolescents with cancer and families (N = 126 dyads) at four tertiary pediatric hospitals. Adolescents were aged 14-21 years, English speaking, cancer diagnosis, not developmentally delayed, psychotic, homicidal, suicidal, or severely depressed. Latent class analysis and multinomial logit models were used for analysis. Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric symptom measures, Short forms, evaluated anxiety, depressive symptoms, pain interference, and fatigue. Family-reported household income used 2016 Federal Poverty Level (FPL) guidelines., Results: Three distinct groups of patients were identified using PROMIS symptom patterns: High Distress-25%; High Physical/Low Psychological Distress-14%; and Low Distress-62%. Female adolescents living in households with incomes at or below the 2016 FPL had 30 times the odds of being classified in the High Distress class (higher probabilities of experiencing anxiety, depressive symptoms, pain interference, and fatigue) compared to those in the High Physical/Low Psychological Distress class (female and poverty: AOR = 30.27, 95% CI 1.23, 735.10), and this was statistically significant (β = 3.41, 95% CI 0.21, 6.60; p = .04) but not compared to those in Low Distress., Conclusion: Adolescent females with cancer with households in poverty had significantly greater odds of experiencing high symptom distress, compared to those with high physical but low psychological distress. More comprehensive screening and intervention, as needed, may decrease disparities., (© 2021 The Authors. Pediatric Blood & Cancer published by Wiley Periodicals LLC.)

Background and Objectives: Little is known about how families respond to pediatric advance care planning. Physicians are concerned that initiating pediatric advance care planning conversations with families is too distressing for families. We examined the effect of family centered pediatric advance care planning intervention for teens with cancer (FACE-TC) advance care planning on families' appraisals of their caregiving, distress, and strain., Methods: In a randomized clinical trial with adolescents with cancer and their families conducted from July 2016 to April 2019 in 4 tertiary pediatric hospitals, adolescents and family dyads were randomly assigned at a 2:1 intervention/control ratio to either the 3 weekly sessions of FACE-TC (Advance Care Planning Survey; Next Steps: Respecting Choices; Five Wishes) or treatment-as-usual. Only the family member was included in this study. Generalized estimating equations assessed the intervention effect measured by Family Appraisal of Caregiving Questionnaire., Results: Families' ( n = 126) mean age was 46 years; 83% were female, and 82% were white. FACE-TC families significantly increased positive caregiving appraisals at 3-months postintervention, compared with those in the control group (β = .35; 95% confidence interval [CI] 0.19 to 0.36; P = .03). No significant differences were found between groups for strain (β = -.14; 95% CI = -0.42 to 0.15; P = .35) or distress (β = -.01; CI = -0.35 to 0.32; P = .93)., Conclusions: Families benefited from participation in FACE-TC, which resulted in positive appraisals of their caregiving for their child with cancer, while not significantly burdening them with distress or strain. Clinicians can be assured of the tolerability of this family-supported model., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Lyon is receiving grant support from the American Cancer Society outside the submitted work to translate and adapt family centered pediatric advance care planning for teens with cancer for Spanish speaking adolescents and their families.

Context: Children and adolescents with cancer experience treatment-related, subjective adverse events (AEs). Identifying distinct groups of patients who predictably experience higher prevalence of AEs could guide patient care., Objectives: Study aims were to 1) identify groups of children and adolescents reporting AEs using the Pediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE); 2) determine whether demographic and clinical characteristics predict AE group membership; and 3) examine whether AE group membership was related to the distal outcome of psychological stress., Methods: Four hundred seventy-seven patients self-reported AEs via the Ped-PRO-CTCAE at T1 (beginning of treatment) and the PROMIS Pediatric Psychological Stress measure at T2 (7-28 days later). Latent class analysis was conducted to identify groups of patients and the relationships of the groups with demographic and clinical characteristics, and with stress., Results: Three distinct a priori unknown AE groups were identified (high AE prevalence, moderate AE prevalence, and low AE prevalence). Females, blacks, patients with high psychological stress, and patients more recently diagnosed were more likely to be in the high AE prevalence group. Gender, age, race, and time since diagnosis were associated with psychological stress., Conclusion: Children with cancer are heterogeneous in experiencing subjective AEs. Gender, race, and time since diagnosis were significantly associated with higher subjective AE prevalence that may lead to psychological stress., (Copyright © 2020 American Academy of Hospice and Palliative Medicine.

Symptomatic peri-acetabular metastatic lesions are often treated with open surgery such as modified Harrington procedures. In an effort to avoid surgical complications inherently associated with open surgical approaches, we developed and recently reported a novel Tripod percutaneous screw technique. The tripod technique is minimally invasive and was found to yield excellent outcomes regarding both pain control and functionality. The procedure is performed in a standard operative theater using fluoroscopic guided percutaneous screws. Despite the simplicity of intraoperative set-up and instrumentation, it is technically demanding. Obtaining the correct fluoroscopic views and troubleshooting intraoperative hurdles can be challenging for even an experienced orthopedic surgeon. The technique and bony conduits were previously described in the trauma literature, however, there are key points of difference in the setting of metastatic disease. Here we provide a compilation of a stepwise graphic guide for the tripod model in the setting of metastatic peri-acetabular lesions, as well as the tips and tricks based on our own experience. These encompass preoperative preparation, operating room settings, intraoperative fluoroscopic guidance, postoperative care, and subsequent conversion to a cemented total hip arthroplasty, if needed., (© 2021 Wiley Periodicals LLC.)

Background: FAmily CEntered (FACE) Advance Care Planning helps family decision makers to understand and honor patients' preferences for future health care, if patients cannot communicate. Spiritual well-being is a key domain of pediatric oncology care and an integral dimension of pediatric advance care planning., Procedure: As part of four-site randomized controlled trial of FACE for teens with cancer, the functional assessment of chronic illness therapy-spiritual well-being- version 4 (FACIT-Sp-EX-4) was completed independently by 126 adolescents with cancer/family dyads. The prevalence-adjusted and bias-adjusted kappa (PABAK) measured congruence on FACIT-Sp-EX-4., Results: Adolescents (126) had mean age of 16.9 years, were 57% female and 79% White. Religious/spiritual classifications were: Catholic (n = 18), Protestant (n = 76), Mormon (n = 3), none/atheist (n = 22), other (n = 5), and unknown (n = 2). Agreement at item level between spiritual well-being of adolescents and families was assessed. Three items had ≥90% agreement and Excellent PABAK: "I have a reason for living," "I feel loved," "I feel compassion for others in the difficulties they are facing." Three items had <61% agreement and Poor PABAK: "I feel a sense of harmony within myself," "My illness has strengthened my faith or spiritual beliefs," "I feel connected to a higher power (or God)." Dyadic congruence was compared by social-demographics using median one-way analysis. Male family members (median = 72%) were less likely to share spiritual beliefs with their adolescent than female family members (median = 83%), P = .0194., Conclusions: Family members may not share spiritual beliefs with adolescents and may be unaware of the importance of spiritual well-being for adolescents., (© 2020 Wiley Periodicals LLC.)

Importance: The associations of spiritual and religious factors with patient-reported outcomes among adolescents with cancer are unknown., Objective: To model the association of spiritual and religious constructs with patient-reported outcomes of anxiety, depressive symptoms, fatigue, and pain interference., Design, Setting, and Participants: This cross-sectional study used baseline data, collected from 2016 to 2019, from an ongoing 5-year randomized clinical trial being conducted at 4 tertiary-referral pediatric medical centers in the US. A total of 366 adolescents were eligible for the clinical trial, and 126 were randomized; participants had to be aged 14 to 21 years at enrollment and be diagnosed with any form of cancer. Exclusion criteria included developmental delay, scoring greater than 26 on the Beck Depression Inventory II, non-English speaking, or unaware of cancer diagnosis., Exposures: Spiritual experiences, values, and beliefs; religious practices; and overall self-ranking of spirituality's importance., Main Outcomes and Measures: Variables were taken from the Brief Multidimensional Measurement of Religiousness/Spirituality (ie, feeling God's presence, daily prayer, religious service attendance, being very religious, and being very spiritual) and the spiritual well-being subscales of the Functional Assessment of Chronic Illness Therapy (meaning/peace and faith). Predefined outcome variables were anxiety, depressive symptoms, fatigue, and pain interference from Patient-Reported Outcomes Measurement Information System pediatric measures., Results: A total of 126 individuals participated (72 [57.1%] female participants; 100 [79.4%] white participants; mean [SD] age, 16.9 [1.9] years). Structural equation modeling showed that meaning and peace were inversely associated with anxiety (β = -7.94; 95% CI, -12.88 to -4.12), depressive symptoms (β = -10.49; 95% CI, -15.92 to -6.50), and fatigue (β = -8.90; 95% CI, -15.34 to -3.61). Feeling God's presence daily was indirectly associated with anxiety (β = -3.37; 95% CI, -6.82 to -0.95), depressive symptoms (β = -4.50; 95% CI, -8.51 to -1.40), and fatigue (β = -3.73; 95% CI, -8.03 to -0.90) through meaning and peace. Considering oneself very religious was indirectly associated with anxiety (β = -2.81; 95% CI, -6.06 to -0.45), depressive symptoms (β = -3.787; 95% CI, -7.68 to -0.61), and fatigue (β = -3.11, 95% CI, -7.31 to -0.40) through meaning and peace. Considering oneself very spiritual was indirectly associated with anxiety (β = 2.11; 95% CI, 0.05 to 4.95) and depression (β = 2.8, 95% CI, 0.07 to 6.29) through meaning and peace. No associations were found between spiritual scales and pain interference., Conclusions and Relevance: In this study, multiple facets of spirituality and religiousness were associated with anxiety, depression, and fatigue, all of which were indirectly associated with the participant's sense of meaning and peace, which is a modifiable process. Although these results do not establish a causal direction, they do suggest palliative interventions addressing meaning-making, possibly including a spiritual or religious dimension, as a novel focus for intervention development.

Importance: Lack of pediatric advance care planning has been associated with poor communication, increased hospitalization, poor quality of life, and legal actions. Clinicians presume that families understand adolescents' treatment preferences for end-of-life care., Objective: To examine patient-reported end-of-life values and needs of adolescents with cancer and congruence with their families' understanding of these needs., Design, Setting, and Participants: This cross-sectional survey was conducted among adolescent-family dyads from July 16, 2016, to April 30, 2019, at 4 tertiary care pediatric US hospitals. Participants included 80 adolescent-family dyads (160 participants) within a larger study facilitating pediatric advance care planning. Adolescent eligibility criteria included being aged 14 to 21 years, English speaking, being diagnosed with cancer at any stage, and knowing their diagnosis. Family included legal guardians for minors or chosen surrogate decision-makers for those aged 18 years or older. Data analysis was performed from April 2019 to November 2019., Exposure: Session 1 of the 3-session Family Centered Pediatric Advance Care Planning for Teens With Cancer intervention., Main Outcomes and Measures: The main outcome was congruence between adolescents with cancer and their families regarding adolescents' values, goals, and beliefs about end-of-life care. Prevalence-adjusted and bias-adjusted κ (PABAK) values were used to measure congruence on the Lyon Advance Care Planning Survey-Revised (Patient and Surrogate versions)., Results: A total of 80 adolescent-family dyads (160 participants) were randomized to the intervention group in the original trial. Among the adolescents, 44 (55.0%) were female and 60 (75.0%) were white, with a mean (SD) age of 16.9 (1.8) years. Among family members, 66 (82.5%) were female and 65 (81.3%) were white, with a mean (SD) age of 45.3 (8.3) years. Family members' understanding of their adolescent's beliefs about the best time bring up end-of-life decisions was poor: 86% of adolescents wanted early timing (before getting sick, while healthy, when first diagnosed, when first sick from a life-threatening illness, or all of the above), but only 39% of families knew this (PABAK, 0.18). Families' understanding of what was important to their adolescents when dealing with their own dying was excellent for wanting honest answers from their physician (PABAK, 0.95) and understanding treatment choices (PABAK, 0.95) but poor for dying a natural death (PABAK, 0.18) and being off machines that extend life, if dying (PABAK, 0)., Conclusions and Relevance: Many families had a poor understanding of their adolescent's values regarding their own end-of-life care, such as when to initiate end-of-life conversations and preference for being off machines that extend life. Pediatric advance care planning could minimize these misunderstandings with the potential for a substantial impact on quality of care.

Background: The Pediatric Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to measure symptoms and functions of children with a variety of chronic diseases. As the Chinese version of pediatric PROMIS (C-Ped-PROMIS) measures was developed, the measurement properties of C-Ped-PROMIS have not been demonstrated., Objective: The aim of this study was to examine the reliability, validity, and factorial structure of the C-Ped-PROMIS measures in children with cancer in China., Methods: A total of 272 children and adolescents were recruited from 3 hospitals in China. The 8 C-Ped-PROMIS measures and Pediatric Quality of Life Inventory General Core Module and Cancer Module were administered in a cross-sectional design. Known-group validity, concurrent validity, and item and scale reliability of these 8 measures were examined by using SPSS 21.0, and factorial structures were tested by using confirmatory factor analysis with Mplus 7.1., Results: All 8 C-Ped-PROMIS measures showed good known-group validity as hypothesized (P < .05) and good concurrent validity measured by significant correlations with the Pediatric Quality of Life Inventory General Core Module and Cancer Module; the correlation coefficients ranged from r = 0.519 to r = 0.655, except for peer relationship with r = 0.255 and r = 0.136, respectively. The Cronbach's α of C-Ped-PROMIS ranged from .758 to .910, and model-estimated scale reliabilities ranged from 0.740 to 0.905. The confirmatory factor analysis models of each measure fit data very well., Conclusions: All 8 C-Ped-PROMIS measures have a valid factorial structure as theoretically defined with good reliability and validity., Implications for Practice: The C-Ped-PROMIS can be readily used to measure symptoms and functions of children and adolescents with cancer in China.

Purpose: This study assessed the responsiveness to change over time and theorized associations of Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric measures in children and adolescents in treatment for cancer to determine measure readiness for use in cancer clinical trials., Methods: We administered eight PROMIS (three symptom, two psychological, and three performance) pediatric short-form measures and the Symptom Distress Scale (SDS) to 96 pediatric oncology patients at three time points during a course of chemotherapy. We assessed responsiveness using paired t tests and generalized estimating equation (GEE) models, calculated standardized response mean (SRM) values for PROMIS measures, and examined scores over three data points (T1-T3). Guided by the theory of unpleasant symptoms (TOUS), we examined associations among the PROMIS measures, the SDS, and other variables using GEE., Results: The paired t tests showed statistically significant changes in two psychological measures and one performance measure from T1 to T2; three symptom, two psychological and two performance measures from T2 to T3; and three symptom and two psychological measures from T1 to T3. Findings from GEE models indicate PROMIS pediatric measures had statistically significant short-term and long-term changes, controlling for demographic and clinical variables. One performance measure did not achieve significant change at any time point. We found positive support for theorized relationships in the TOUS., Conclusions: Most of the PROMIS pediatric measures demonstrated changes over time and had significant relationships as theorized, thus supporting concurrent and construct validity of these measures when administered to pediatric oncology patients during a course of chemotherapy. This evidence supports the measures' readiness for use in clinical trials., (© 2019 Wiley Periodicals, Inc.)

Context: Children in treatment for cancer experience multiple, troubling, and interrelated symptoms. Analyzing the interrelatedness of symptoms and how that changes during treatment could yield clinically relevant patient profiles to guide patient care., Objectives: The aims were to identify pediatric profiles with respect to Patient-Reported Outcomes Measurement Information System ® (PROMIS ® ; U.S. Department of Health and Human Services, National Institutes of Health) symptom measures, changes in profile status throughout a chemotherapy cycle, and if a baseline single-item fatigue measure could significantly predict symptom profile status and its changes., Methods: In a longitudinal, single-site, three data point (T1, T2, and T3) design, children between 8 and 18 years completed the PROMIS Pediatric short form measures for fatigue, depression, anxiety, and pain and one fatigue item from the Symptom Distress Scale. Latent profile analysis and latent transition analysis were conducted., Results: About 96 children participated; 58.3% were between 13 and 18 years, and 54.2% were males. Two latent profiles (less severe symptoms and severe symptoms) were identified. The prevalence of the severe symptom profile remained relatively unchanged from T1 to T2 but significantly declined at T3. The baseline single-item fatigue score significantly predicted the child's profile membership and its changes., Conclusion: Children experiencing troubling symptoms during cancer treatment are heterogeneous. With respect to the PROMIS symptom measures, two a priori unknown distinct latent profiles of patients were identified in a course of chemotherapy, and the transitions in the profile status were significantly predicted by a baseline single-item fatigue measure., (Copyright © 2017 American Academy of Hospice and Palliative Medicine.

Objectives: To compare Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Fatigue Short Form measures and legacy patient-reported outcome fatigue measures to capture cancer-related fatigue change in pediatric patients with cancer. 
., Sample & Setting: 96 racially diverse children and adolescents with cancer. The study occurred in a 32-bed inpatient unit and three regional outpatient clinics.
., Methods & Variables: The Fatigue Scale-Child, Fatigue Scale-Adolescent, and the PROMIS Pediatric Fatigue Short Form measures were administered at three time points during chemotherapy. Descriptive, correlational, psychometric, and receiver operating characteristic (ROC) curve analyses were conducted. The variable was pediatric patient-reported fatigue.
., Results: All measures were positively correlated at each time point. ROC curves were not statistically different from each other at any data point. 
., Implications for Nursing: Nurses have psychometrically strong options for measuring cancer-related fatigue in pediatric patients with cancer, but the PROMIS Pediatric Fatigue Short Form is applicable to more age groups.

Cancer is the leading cause of disease-related death for adolescents and young adults (AYAs) in the United States. Parents of AYAs with life-threatening illnesses have expressed the desire to talk to their children about end of life (EOL) care, yet, like caregivers of adult patients, struggle to initiate this conversation. Building Evidence for Effective Palliative/End of Life Care for Teens with Cancer is a longitudinal, randomized, controlled, single-blinded clinical trial aimed at evaluating the efficacy of FAmily CEntered disease-specific advance care planning (ACP) for teens with cancer (FACE-TC). A total of 130 dyads (260 subjects) composed of AYAs 14-20years old with cancer and their family decision maker (≥18years old) will be recruited from pediatric oncology programs at Akron Children's Hospital and St. Jude Children's Research Hospital. Dyads will be randomized to either the FACE-TC intervention or Treatment as Usual (TAU) control. FACE-TC intervention dyads will complete three 60-minute ACP sessions held at weekly intervals. Follow-up data will be collected at 3, 6, 12, and 18months post-intervention by a blinded research assistant (RA). The effects of FACE-TC on patient-family congruence in treatment preferences, quality of life (QOL), and advance directive completion will be analyzed. FACE-TC is an evidenced-based and patient-centered intervention that considers QOL and EOL care according to the AYA's representation of illness. The family is involved in the ACP process to facilitate shared decision making, increase understanding of the AYA's preferences, and make a commitment to honor the AYA's wishes., (Copyright © 2017 Elsevier Inc.

Purpose: Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric forms measure symptoms and function of pediatric patients experiencing chronic disease by using the same measures. Comparability is one of the most important purposes of the PROMIS initiative. This study aimed to test the factorial structures of four symptom measures (i.e., Anxiety, Depression, Fatigue, and Pain Interference) in the original English and the Chinese versions and examine the measurement invariance of the measures across two cultures., Methods: Four PROMIS Pediatric measures were used to assess symptoms, respectively, in Chinese (n = 232) and American (n = 200) children and adolescents (8-17 years old) in treatment for cancer or in survivorship. The categorical confirmatory factor analysis (CCFA) model was used to examine factorial structures, and multigroup CCFA was applied to test measurement invariance of these measures between the Chinese and American samples., Results: The CCFA models of the four PROMIS Pediatric symptom measures fit the data well for both the Chinese and American children and adolescents. Minor partial measurement invariance was identified. Factor means and factor variances of the four PROMIS measures were not significantly different between the two populations., Conclusions: Our results provide evidence that the four PROMIS Pediatric symptom measures have valid factorial structures and a statistical property of measurement invariance across American and Chinese children and adolescents with cancer. This means that the items of these measures were interpreted in a conceptually similar manner by two groups. They could be readily used for meaningful cross-cultural comparisons involving pediatric oncology patients in these two countries.

Background: Adolescents with cancer experience many troubling symptoms, including sleep disruptions that can affect mood and quality of life. Massage is a safe and popular intervention that has demonstrated efficacy in pediatric and adult patients with cancer. This study aimed to assess the feasibility of conducting a massage intervention to help with sleep in hospitalized adolescent oncology patients., Procedure: Adolescents ages 12-21 with cancer who were expected to be hospitalized for at least four consecutive nights were recruited from the inpatient unit at Children's National Health System and randomized to either massage intervention or a waitlist control. Patients in the intervention group received one massage per night, for two or three nights. Sleep was measured with actigraphy and patient and proxy reported instruments were used to measure fatigue, mood, and anxiety., Results: The majority (78%) of patients approached for the study consented, and almost all patients in the intervention group (94%) received at least one massage, 69% received two, and rates of completion of instruments among adolescents were high demonstrating feasibility. There were trends toward increased night time and overall sleep in the intervention group compared with standard of care, but no differences between groups in the patient reported outcome measures. Participant and parent feedback on the intervention was positive and was the impetus for starting a clinical massage service at the hospital., Conclusions: Massage for hospitalized adolescents with cancer is feasible, well received, and can potentially improve patients' sleep. A randomized multicenter efficacy study is warranted., (© 2016 Wiley Periodicals, Inc.)

Purpose: The pediatric patient-reported outcomes measurement information system (PROMIS) was developed to provide self-reported item banks and short forms for children and adolescents (aged 8-17 years) experiencing a chronic illness to assess their quality of life and symptoms. The pediatric PROMIS short forms have been translated into Chinese and applied in children with cancer in China. This study aimed to describe psychometric properties of the Anxiety and Depression measures., Methods: A total of 232 children and adolescents with cancer were recruited in hospital-based inpatient and outpatient clinics. Eight Chinese versions of pediatric PROMIS (C-Ped-PROMIS) measures were administered. Categorical confirmatory factor analysis (CCFA) were conducted to evaluate scale dimensionality and item local dependence of the C-Ped-PROMIS Anxiety and Depression items. Multiple indicator multiple cause models were used to analyze differential item functioning (DIF), item response theory parameters were calculated, and test information against T scores was reported for each measure., Results: The results of the CCFA confirmed that both C-Ped-PROMIS Anxiety and Depression scales appropriately measure the theoretical constructs as designed. No significant DIF was found for the items of the two scales according to age and gender. Both scales have high test reliability as long as their T scores are not on the low or high extremes., Conclusions: The pediatric PROMIS Anxiety and Depression measures were developed to provide efficient and flexible assessment of emotional distress domains. Our results provide evidence that the two C-Ped-PROMIS measures can be readily applied to measure anxious and depressive symptoms in Chinese children with cancer.

Background: Little is known about how well family members accurately represent adolescents when making EOL decisions on their behalf. This study reports on surveys given to adolescents with cancer and their parents as part of a larger study facilitating advanced care discussions, as well as the results of a survey for health care providers., Procedure: Trained facilitators administered surveys orally to adolescents and families in the intervention arm of the FAmily CEntered Advance Care Planning (ACP) for Teens with Cancer (FACE-TC) study. In addition, a post-hoc survey was sent to oncology providers., Results: Seventeen adolescent/family dyads completed this survey. Seventy five percent of adolescents believed it was appropriate to discuss EOL decisions early and only 12% were not comfortable discussing death. Most preferred to be at home if dying. There were substantial areas of congruence between adolescents and their surrogates, but lower agreement on the importance of dying a natural death, dying at home and "wanting to know if I were dying." Among providers, 83% felt their patients' participation in the study was helpful to the patients and 78% felt it was helpful to them as providers., Conclusions: Adolescents with cancer were comfortable discussing EOL, and the majority preferred to talk about EOL issues before they are facing EOL. There were substantive areas of agreement between adolescents and their surrogates, but important facets of adolescents' EOL wishes were not known by their families, reinforcing the importance of eliciting individual preferences and engaging dyads so parents can understand their children's wishes., (© 2014 Wiley Periodicals, Inc.)

Background: The Strategies Used by People to Promote Health (SUPPH) is an instrument used to measure self-reported self-efficacy in patient populations. Self-efficacy has a major impact on quality of life and psychological well-being. Previous findings of dimensionality of the SUPPH vary, and cultural differences exist suggesting the need for further investigation and psychometric testing to establish construct validity of the SUPPH in different cultures., Objective: The purpose of this study was to examine the factorial structure of the Chinese version of the SUPPH (C-SUPPH)., Methods: Using reports from 764 oncology patients in China, the factorial structure of the C-SUPPH was assessed via 2 analytical strategies. First-order confirmatory factor analysis (CFA) models were used to examine the dimensionality of the C-SUPPH; a second-order CFA was used to determine the existence of a factorial structure hierarchy of the C-SUPPH., Results: Compared with the 2- and 4-factor solutions, the 3-factor CFA of the C-SUPPH had a better fit with the data (comparative fit index = 0.94, Tucker-Lewis index = 0.94, root-mean-square error of approximation = 0.05, the close-fit test P = .565, and standardized root-mean-square residual = 0.04). Our findings confirmed the 3-scale structure: Positive Attitude, Stress Reduction, and Making Decisions; together, the 3 factors represent an underlying higher-order factor, that of general self-care self-efficacy., Conclusions: The C-SUPPH has a valid factorial structure and can be readily applied to studying self-efficacy in Chinese patients who are diagnosed with cancers., Implications for Practice: Our findings provide support for a culturally sensitive, reliable, and valid self-efficacy measure (the C-SUPPH) of Chinese adult cancer patients' self-care self-efficacy.

Background: Children with cancer experience multiple symptoms due to their disease and as a result of treatment. The purpose of this study was to demonstrate the feasibility and potential utility of using latent profile analysis (LPA), a type of cluster analysis, in children with cancer to identify groups of patients who experience similar levels of symptom severity and impairment of physical function., Procedure: We analyzed patient-reported symptom and functional data previously collected using the Pediatric Patient Reported Outcomes Measurement Information System (PROMIS). LPA was used to identify and characterize groups of patients who reported similar levels of symptom severity and functional impairment. We then used the multinomial logit model to examine demographic and disease characteristics associated with symptom/function profile membership., Results: The analysis included 200 patients in treatment or in survivorship. We identified four symptom/function profiles; children currently receiving cancer treatment and those with at least one other medical problem were more likely to be members of the profile with the highest levels of symptom severity and functional impairment. Gender, age, race/ethnicity, and tumor type were not associated with profile membership., Conclusions: LPA is a cluster research methodology that provides clinically useful results in pediatric oncology patients. Future studies of children with cancer using LPA could potentially lead to development of clinical scoring systems that predict patients' risk of developing more severe symptoms and functional impairments, allowing clinicians, patients, and parents to better anticipate and prevent the multiple symptoms that occur during and after treatment for childhood cancer., (© 2014 Wiley Periodicals, Inc.)

Introduction: Although the relationship between partial socioeconomic status (SES) and self-efficacy has been studied in previous studies, few research have examined self-efficacy difference among patients with cancer with different SES., Methods: A cross-sectional survey involving 764 patients with cancer was completed. Latent class analysis (LCA) was applied to identify distinct groups of patients with cancer using four SES indicators (education, income, employment status and health insurance status). Standardization and decomposition analysis (SDA) was then used to examine differences in patients' self-efficacy among SES groups and the components of the differences attributed to confounding factors, such as gender, age, anxiety, depression and social support., Results: Participants were classified into four distinctive SES groups via using LCA method, and the observed self-efficacy level significantly varied by SES groups; as theorized, higher self-efficacy was associated with higher SES. The self-efficacy differences by SES groups were decomposed into "real" group differences and factor component effects that are attributed to group differences in confounding factor compositions., Conclusion: Self-efficacy significantly varies by SES. Social support significantly confounded the observed differences in self-efficacy between different SES groups among Chinese patients with cancer., (Copyright © 2014 Elsevier Ltd.

Purpose: To test the feasibility, acceptability and safety of a pediatric advance care planning intervention, Family-Centered Advance Care Planning for Teens With Cancer (FACE-TC)., Methods: Adolescent (age 14-20 years)/family dyads (N = 30) with a cancer diagnosis participated in a two-armed, randomized, controlled trial. Exclusion criteria included severe depression and impaired mental status. Acceptability was measured by the Satisfaction Questionnaire. General Estimating Equations models assessed the impact of FACE-TC on 3-month post-intervention outcomes as measured by the Pediatric Quality of Life Inventory 4.0 Generic Core Scale, the Pediatric Quality of Life Inventory 4.0 Cancer-Specific Module, the Beck Depression and Anxiety Inventories, the Spiritual Well-Being Scale of the Functional Assessment of Chronic Illness Therapy-IV, and advance directive completion., Results: Acceptability was demonstrated with enrollment of 72% of eligible families, 100% attendance at all three sessions, 93% retention at 3-month post-intervention, and 100% data completion. Intervention families rated FACE-TC worthwhile (100%), whereas adolescents' ratings increased over time (65%-82%). Adolescents' anxiety decreased significantly from baseline to 3 months post-intervention in both groups (β = -5.6; p = .0212). Low depressive symptom scores and high quality of life scores were maintained by adolescents in both groups. Advance directives were located easily in medical records (100% of FACE-TC adolescents vs. no controls). Oncologists received electronic copies. Total Spirituality scores (β = 8.1; p = .0296) were significantly higher among FACE-TC adolescents versus controls. The FACE-TC adolescents endorsed the best time to bring up end-of-life decisions: 19% before being sick, 19% at diagnosis, none when first ill or hospitalized, 25% when dying, and 38% for all of the above., Conclusions: Family-Centered Advance Care Planning for Teens With Cancer demonstrated feasibility and acceptability. Courageous adolescents willingly participated in highly structured, in-depth pediatric advance care planning conversations safely., (Copyright © 2014 Society for Adolescent Health and Medicine.

Background and Purpose: The Chinese version of the Strategies Used by Patients to Promote Health (C-SUPPH) is a self-report instrument used to measure self-efficacy among patients with cancer. The purpose of this article is to examine measurement invariance of C-SUPPH using data of 764 cancer patients recruited in China., Methods: Multigroup confirmatory factor analysis (CFA) models were applied across the selected sociodemographic groups of gender, age, education, and monthly income levels., Results: The factorial structure and factor loadings (relationships between items and their underlying factors) of C-SUPPH were invariant across all sociodemographic groups., Conclusions: The findings showed that the C-SUPPH measures the same latent constructs/factors in the same way when administered to different sociodemographic groups and thus can be readily applied to studying self-efficacy of cancer patients in China.

Background: Patient-reported outcomes related to symptoms, function, and quality of life during and following cancer treatment can guide care for pediatric cancer patients. To advance the science of patient-reported outcomes, the National Institutes of Health funded the Patient-Reported Outcomes Measurement Information System (PROMIS)., Objective: The objective of this study was to assess feasibility and acceptability of the PROMIS pediatric measures, as defined by enrollment and attrition rates as well as missingness by measure, item, participant, and assessment time point., Methods: Eight- to 18-year-olds participated in 2 studies: PROMIS I, a cross-sectional study of children in active cancer treatment or survivorship, and PROMIS II, a longitudinal study with 3 assessment time points for children receiving curative treatment., Results: PROMIS I (n = 200) and PROMIS II (n = 94) had enrollment rates of 92.5% and 89.7%, respectively. For PROMIS I, measure missingness was acceptable (8% missed any measures) and was not related to other study variables. For PROMIS II, measure missingness was minimal (0.8%), and item-level missingness was relatively low. In general, items that were skipped asked about experiences that participants had not encountered in the past 7 days., Conclusions: In both studies, the PROMIS instruments demonstrated good feasibility and acceptability among pediatric cancer patients. Overall, we had high enrollment, low attrition, and acceptable rates of measure and item missingness., Implications for Practice: Our results demonstrate that PROMIS measures are acceptable to 8- to 18-year-olds in different points of cancer care and feasible for use in pediatric cancer inpatient and outpatient settings.

Importance: Advance care planning (ACP) prepares patients and their families for future health care decisions; however, the needs of adolescent oncology patients for participation in ACP have not been well studied., Objective: To examine the efficacy of family-centered ACP., Design and Setting: Two-group randomized controlled trial in a pediatric oncology program., Participants: Sixty adolescents aged 14 to 21 years with cancer and their surrogates or families were enrolled in the study between January 17, 2011, and March 29, 2012., Intervention: Thirty dyads received 3- to 60-minute sessions 1 week apart. Intervention dyads completed (1) the Lyon Family-Centered ACP Survey, (2) the Respecting Choices interview, and (3) Five Wishes. Control subjects received standard care plus information., Main Outcome Measures: Statement of treatment preferences and Decisional Conflict Scale score., Results: The mean age of the adolescents was 16 years; 36 (60%) were male, 30 (50%) white, 26 (43%) black, and 4 (7%) Asian. Diagnoses were as follows: leukemia (14 patients [47%]), brain tumor (8 [27%]), solid tumor (6 [20%]), and lymphoma (2 [7%]). Significantly increased congruence was observed for intervention dyads compared with controls for 4 of the 6 disease-specific scenarios; for example, for situation 2 ("treatment would extend my life by not more than 2 to 3 months"), intervention dyads demonstrated higher congruence (κ = 0.660; P < .001) vs control dyads (κ = -0.0636; P = .70). Intervention adolescents (100%) wanted their families to do what is best at the time, whereas fewer control adolescents (62%) gave families this leeway. Intervention adolescents were significantly better informed about end-of-life decisions (t = 2.93; effect size, 0.961; 95% CI, 0.742-1.180; P = .007). Intervention families were more likely to concur on limiting treatments than controls. An ethnic difference was found in only one situation., Conclusions: Advance care planning enabled families to understand and honor their adolescents' wishes. Intervention dyads were more likely than controls to limit treatments. Underserved African American families were willing to participate.

Background: Establishing the ability of children and adolescents with cancer to complete the NIH-sponsored PROMIS pediatric measures electronically and the preliminary validity estimates of the measures (both full item banks and short forms) in pediatric oncology will contribute to our knowledge of the impact of cancer treatment on these young patients., Procedures: A total of 203 8- to 17-year olds were administered eight PROMIS pediatric measures in a cross-sectional study design to establish known-group validity. Of the 200 who completed all or most of the items, a slight majority were male (55.5%) and white (54%). Patients were either undergoing treatment for cancer (n = 93) or in survivorship following treatment for cancer (n = 107). Measures were completed using computer interface during an in-person interaction with researchers., Results: Only 3 of 203 participants did not complete the PROMIS pediatric measures. As hypothesized, participants in treatment were significantly different (worse) on parent-reported clinical indicators (blood counts, fatigue, and appetite) and on seven self-reported measures (depression, anxiety, peer relationships, pain interference, fatigue, upper extremity function, and mobility) from participants in survivorship. Females reported worse fatigue, anger, and pain interference than males. Worse patient-reported outcomes for patients in active treatment persisted after adjusting for potential confounding variables., Conclusions: Children and adolescents in treatment for cancer or in survivorship and ranging from 8 to 17 years of age can complete multiple PROMIS pediatric measures using a computer interface during an outpatient clinic visit or inpatient admission. Findings establish known-group validity for PROMIS pediatric measures in pediatric oncology., (Copyright © 2012 Wiley Periodicals, Inc.)
