Psychometric properties of the DISABKIDS Chronic Generic Module (DCGM-37) when used in children undergoing treatment for cancer

Clinical outcomes measurement in pediatric lower limb prosthetics: A scoping review

OBJECTIVE

This study aimed to identify clinical measures that have been used to evaluate function, health related quality of life (HRQoL), and/or satisfaction in children who use lower limb prostheses (LLP). The data reported on psychometric properties for children who use LLP were collected for each measure.

METHODS

First, PubMed, CINAHL, and Web of Science databases were searched using broad search terms to identify standardized outcome measures of function, HRQoL, and/or satisfaction with treatment used in pediatric LLP research published in 2001 or after. For each of the eligible measures found, a second search was performed to identify psychometric properties (e.g., validity, reliability) assessed with children who use LLP.

RESULTS

Forty-four standardized outcome measures were identified from 41 pediatric LLP research articles. Five measures (i.e., Gait Outcomes Assessment for Lower Limb Differences, Functional Mobility Assessment, Child Amputee Prosthetics Project- Prosthesis Satisfaction Inventory, Child Amputee Prosthetics Project- Functional Scale Index, and Lower Limb Function Questionnaire) had data on psychometric properties for children who use LLP.

CONCLUSIONS

Few studies report psychometric data for assessing the overall HRQoL, function, and/or satisfaction for children who use LLP. Further research is needed to validate or create new outcome measures that assess the HRQoL, satisfaction, and/or function of children who use LLP.

A critical evaluation of the content validity of patient-reported outcome measures assessing health-related quality of life in children with cancer: a systematic review

BACKGROUND

With increasing survival rates in pediatric oncology, the need to monitor health-related quality of life (HRQOL) is becoming even more important. However, available patient-reported outcome measures (PROMs) have been criticized. This review aims to systematically evaluate the content validity of PROMs for HRQOL in children with cancer.

METHODS

In December 2021, a systematic literature search was conducted in PubMed. PROMs were included if they were used to assess HRQOL in children with cancer and had a lower age-limit between 8 and 12 years and an upper age-limit below 21 years. The COSMIN methodology for assessing the content validity of PROMs was applied to grade evidence for relevance, comprehensiveness, and comprehensibility based on quality ratings of development studies (i.e., studies related to concept elicitation and cognitive interviews for newly developed questionnaires) and content validity studies (i.e., qualitative studies in new samples to evaluate the content validity of existing questionnaires).

RESULTS

Twelve PROMs were included. Due to insufficient patient involvement and/or poor reporting, the quality of most development studies was rated 'doubtful' or 'inadequate'. Few content validity studies were available, and these were mostly 'inadequate'. Following the COSMIN methodology, evidence for content validity was 'low' or 'very low' for almost all PROMs. Only the PROMIS Pediatric Profile had 'moderate' evidence. In general, the results indicated that the PROMs covered relevant issues, while results for comprehensiveness and comprehensibility were partly inconsistent or insufficient.

DISCUSSION

Following the COSMIN methodology, there is scarce evidence for the content validity of available PROMs for HRQOL in children with cancer. Most instruments were developed before the publication of milestone guidelines and therefore were not able to fulfill all requirements. Efforts are needed to catch up with methodological progress made during the last decade. Further research should adhere to recent guidelines to develop new instruments and to strengthen the evidence for existing PROMs.

Assessing health-related quality of life in Chinese children and adolescents with cancer: validation of the DISABKIDS chronic generic module (DCGM-37)

Background

With increasing cancer incidence and decreasing cancer mortality, there is a growing need for a valid and culturally adapted tool to measure health-related quality of life in children with cancer. This study validated the DISABKIDS Chronic Generic Module (DCGM-37) in Chinese children and adolescents with cancer.

Methods

The DCGM-37 was translated and adapted for use in China following the guidelines from its copyright holders. In total, 140 children and adolescents with cancer and their guardians were included in this cross-sectional study. Internal consistency and test-retest reliability were evaluated. Convergent validity was examined using Pearson correlation between the DCGM-37 and the PedsQL 4.0 Generic Core Scale. Dimensionality was clarified using exploratory factor analysis. Discriminant validity was evaluated by comparing DCGM-37 scores by sex, age, family income, and clinical characteristics.

Results

Internal consistency (Cronbach’s alpha 0.91) and test–retest reliability were good (intraclass correlation coefficient 0.87, 95% confidence interval 0.73–0.94). Strong correlations between the DCGM-37 and the PedsQL 4.0 (r = 0.83) suggest good convergent validity. Six factors explained 51.94% of the total variance. Children with leukemia scored higher than those with sarcoma in all subscales (effect size ranged from 0.39 to 0.83), especially the “social exclusion” subscales (effect size 0.83). Small to moderate differences (effect size ranged from 0.38 to 0.58) were observed by sex, age, and family income. Neither floor nor ceiling effects were observed.

Conclusion

The DCGM-37 is reliable and valid for measuring health-related quality of life in Chinese children and adolescents with cancer.

The impact of long-term ventilator-use on health-related quality of life and the mental health of children with neuromuscular diseases and their families: need for a revised perspective?

Background

Life extension by medical interventions and health-related quality of life (HRQOL) are sometimes conflicting aspects of medical care. Long-term ventilation in children with neuromuscular disease is a well-established life-extending procedure and often at the center of this conflict. HRQOL and the mental health of affected children and their families become even more important in respect to emerging therapies in neuromuscular diseases with longer life-expectancy of treated patients and considerable costs of medical treatment.

Methods

We performed a questionnaire survey in a total of forty-three families of children with neuromuscular disease treated in the University Medical Center Hamburg-Eppendorf and the Children’s Hospital Altona. We evaluated self- and proxy-reported HRQOL and mental health outcomes of affected children and their parents using validated and age-appropriate instruments.

Results

Compared to normative data, children with neuromuscular diseases and their families experienced a lower HRQOL and mental health. However, there was no additional negative influence on the overall HRQOL by ventilator use.

Conclusions

As ventilator use was not responsible for the reduction of HRQOL and mental health our data contributes an important aspect to the discussion about life-prolonging procedures, in particular mechanical ventilation, in severly disabled patients.

Pretend Play as an Intervention for Children With Cancer: A Feasibility Study

Children with cancer suffer from symptoms and burdensome treatments that often cause distress to children and their families. Mortality is one aspect of cancer diagnosis, while another is the quality of life and well-being during and after the treatment. By supporting children's communication, self-efficacy and coping ability in the care situation, children are given the possibilities for increased independence and participation and are allowed to develop an influence over their care. The aim of this study was to develop and evaluate the feasibility and acceptability of an adult-facilitated pretend play intervention for children with cancer. Five children with ongoing treatment for cancer were invited to a play intervention that consisted of six to eight sessions of structured pretend play aimed at increasing participation, independence, and well-being. A mixed method design was used to evaluate the feasibility and acceptability of the play intervention. Measures were collected before and after interventions, and in conjunction with every play session. Results suggest that the children enjoyed the play intervention. Findings indicate small improvements regarding self-efficacy in care situations and equal or increased quality of life for participants. A main finding was that no adverse events or increased worrying was reported in conjunction with play sessions. Therefore, the intervention is regarded as safe, feasible, and acceptable as reported by participants and their primary caregivers and a possible means of increasing participation and independence in children with a cancer diagnosis.

Young children's experiences of living an everyday life with cancer - A three year interview study

PURPOSE

The young child's experiences of living with cancer are crucial to providing evidence based care. This study explores and describes experiences of everyday life of young children with cancer, over a three year period from diagnosis.

METHOD

This is a longitudinal, inductive interview study with young children with cancer, and their parents. Interviews from shortly after diagnosis, six and 12 months after diagnosis have been reanalysed. Interviews with the same children and their parents from 18 to 36 months after diagnosis have been analysed for the first time in the present paper. A longitudinal temporal analysis at category level for five synchronic data sets forms the basis for the results.

RESULTS

The child living with cancer over a three year period is described as a child apart, striving to live an everyday life. This description is built on three categories: I want to be a child like any other, I need security and control and I feel lonely and left out. Young children with cancer actively strive to understand their illness, participate in care and live an ordinary everyday life- but with ongoing feelings of social isolation and loneliness.

CONCLUSIONS

Young children with cancer need access to and ongoing contact with peers and preschool. A structured follow-up throughout the cancer trajectory and not just during active treatment, is necessary. A child-centred philosophy of care would guide the child towards attainment of health and wellbeing.

Cross-cultural validation of the "DISABKIDS" questionnaire for quality of life among Colombian children with chronic diseases

Objective:

to describe the cross-cultural validation process of the “DISABKIDS” questionnaire in Colombia, for both the children and adolescents’ version and the parents’ version, an instrument intended to measure the health-related quality of life of Colombian children and adolescents with chronic diseases.

Method:

the cross-cultural validation process was conducted according to an international consensual systematic methodology, called standardized linguistic validation, to ensure linguistic equivalence with the original questionnaire.

Results:

the pretest’s cognitive interviews revealed a need to adjust the questionnaire, which consisted of asking for “health condition” rather than only asking for “condition”. Due to the cultural context, the word “condition” used in the original version, when translated to Spanish, refers to socioeconomic conditions rather than health conditions. For this reason, 11 items in the children’s version and eight items in the parents’ version were adjusted.

Conclusions:

the Colombian version of DISABKIDS-37 to measure health-related quality of life among children and adolescents with chronic diseases in both the children’s and parents’ versions is equivalent to the original version and is appropriate for use in Colombia. Future studies can assess the questionnaire’s psychometric properties.

Systematic review of the health-related quality of life issues facing adolescents and young adults with cancer

PURPOSE

For adolescents and young adults (AYAs), the impact of a cancer diagnosis and subsequent treatment is likely to be distinct from other age groups given the unique and complex psychosocial challenges of this developmental phase. In this review of the literature, we report the health-related quality of life (HRQoL) issues experienced by AYAs diagnosed with cancer and undergoing treatment.

METHODS

MEDLINE, EMBASE, CINAHL, PsychINFO and the Cochrane Library Databases were searched for publications reporting HRQoL of AYAs. Issues generated from interviews with AYAs or from responses to patient reported outcome measures (PROMs) were extracted.

RESULTS

166 papers were reviewed in full and comprised 72 papers covering 69 primary studies, 49 measurement development or evaluation papers and 45 reviews. Of the 69 studies reviewed, 11 (16%) used interviews to elicit AYAs' descriptions of HRQoL issues. The majority of the PROMs used in the studies represent adaptations of paediatric or adult measures. HRQoL issues were organised into the following categories: physical, cognitive, restricted activities, relationships with others, fertility, emotions, body image and spirituality/outlook on life.

CONCLUSION

The HRQoL issues presented within this review are likely to be informative to health care professionals and AYAs. The extensive list of issues suggests that the impact of a cancer diagnosis and treatment during adolescence and young adulthood is widespread and reflects the complexities of this developmental phase.

Factors Affecting Health-Related Quality of Life in Children Undergoing Curative Treatment for Cancer: A Review of the Literature

BACKGROUND

Health-related quality of life (HRQoL) is an important measure to evaluate a child's reported treatment experience. Although there are numerous studies of HRQoL in children undergoing curative cancer treatment, there is limited literature on factors that influence this.

OBJECTIVE

To review published studies that describe the HRQoL and associated factors in children undergoing curative cancer treatment.

METHOD

Full-text publications in English from January 2005 to March 2013 were searched in PubMed, PsychINFO, and CINAHL for children ≤18 years of age undergoing curative cancer treatment. HRQoL-associated factors were categorized as cancer diagnosis, treatment, child, family, and community.

RESULTS

Twenty-six studies met the inclusion criteria. The most frequently used generic and cancer-specific instruments were PedsQL (Pediatric Quality of Life Inventory) Generic and PedsQL Cancer, respectively. Cancer diagnosis and treatment were the most frequently identified variables; fewer studies measured family and community domains. Gender, treatment intensity, type of cancer treatments, time in treatment, and cancer diagnosis were correlated with HRQoL.

CONCLUSION

Our study highlights the need to develop interventions based on diagnosis and treatment regimen to improve the HRQoL in children undergoing curative cancer treatment.

Psychometric properties and confirmatory factor analysis of the CASP-19, a measure of quality of life in early old age: the HAPIEE study

OBJECTIVES

The aim was to assess the reliability and validity of the quality of life (QoL) instrument CASP-19, and three shorter versions of CASP-12 in large population sample of older adults from the HAPIEE (Health, Alcohol, and Psychosocial factors In Eastern Europe) study.

METHODS

From the Czech Republic, Russia, and Poland, 13,210 HAPIEE participants aged 50 or older completed the retirement questionnaire including CASP-19 at baseline. Three shorter 12-item versions were also derived from original 19-item instrument. Psychometric validation used confirmatory factor analysis, Cronbach's alpha, Pearson's correlation, and construct validity.

RESULTS

The second-order four-factor model of CASP-19 did not provide a good fit to the data. Two-factor CASP-12v.3 including residual covariances for negative items to account for the method effect of negative items had the best fit to the data in all countries (CFI = 0.98, TLI = 0.97, RMSEA = 0.05, and WRMR = 1.65 in the Czech Republic; 0.96, 0.94, 0.07, and 2.70 in Poland; and 0.93, 0.90, 0.08, and 3.04 in Russia). Goodness-of-fit indices for the two-factor structure were substantially better than second-order models.

CONCLUSIONS

This large population-based study is the first validation study of CASP scale in Central and Eastern Europe (CEE), which includes a general population sample in Russia, Poland, and the Czech Republic. The results of this study have demonstrated that the CASP-12v.3 is a valid and reliable tool for assessing QoL among adults aged 50 years or older. This version of CASP is recommended for use in future studies investigating QoL in the CEE populations.

A Swedish version of the SCREEN II for malnutrition assessment among community-dwelling elderly

Background: The Seniors in the Community: Risk Evaluation for Eating and Nutrition II (SCREEN II) Questionnaire assesses nutritional risk among elderly people living at home. Our aim was to produce a Swedish language version of the SCREEN II and to examine response patterns, data completeness and the relationship between malnutrition and general health. Methods: The SCREEN II was translated into Swedish using dual panel methodology, and then followed up with field test interviews of 24 seniors (median age, 83 years). We used the survey data ( n = 565) to assess item and score distribution, missing responses, and the relationship to the subject’s general and nutritional health. Results: The Swedish SCREEN II was considered easy to understand, respond to, and relevant ( n = 21; 88% of subjects found it so in all three respects) and its median completion time was 5 minutes. The level of survey item data completeness was 94–99%, and 82% of surveys had computable total scores. Of those subjects with completed forms, 35% had no nutritional risk; 35% had moderate risk; and 30% were at high risk. The malnutrition risk increased with poorer perceived health. Conclusions: Our study results are similar to those using previous SCREEN II versions, indicating that the scale adaptation was successful and providing initial support for use of the Swedish SCREEN II Questionnaire.

Survivors of childhood cancer report high levels of independence five years after diagnosis

The aim was to compare self-rated independence in childhood cancer survivors 5 years after diagnosis with corresponding ratings during initial cancer treatment and those in a comparison group. A further aim was to determine whether and how certain clinical and demographic variables affected self-rated independence. Self-rated independence, a dimension included in the health-related quality of life (HRQoL) measure DISABKIDS Chronic Generic Measure (DCGM-37), was assessed in a Swedish cohort of survivors (n = 63, aged 12-22 years) and compared with ratings during initial cancer treatment and those in an age-matched comparison group (n = 257). Potential predictors of self-rated independence were estimated using multiple regression analysis. Survivors rated their independence significantly higher 5 years after diagnosis than during initial cancer treatment and higher than the comparison group. Neither demographic nor clinical variables (age, sex, diagnosis, initial cancer treatment) predicted self-rated independence 5 years post diagnosis. Five years after diagnosis, survivors of childhood cancer appear to have reached a satisfactory level of independence. However, survivors are likely to experience complications over the longer term, and therefore continued follow-up is warranted to follow possible changes in self-reported independence.

Development and testing of a patient-centred care competency scale for hospital nurses

This study aimed to develop and test the psychometric soundness of a patient-centred care competency (PCC) scale for hospital nurses. A cross-sectional questionnaire survey was conducted among 594 nurses in two teaching hospitals (response rate 99.5%). Reliability and validity analyses were performed. The PCC scale consisted of 17 items divided into four subscales: respecting patients' perspectives (6 items), promoting patient involvement in care processes (5 items), providing for patient comfort (3 items) and advocating for patients (3 items). The Cronbach's alpha coefficient of the entire scale was 0.92, and those for the subscales were 0.85, 0.81, 0.84 and 0.80, respectively. Multitrait scaling analysis indicated that the four subscales had satisfactory convergent and discriminant validity. Significant correlations were found between total PCC scores and overall self-ratings of patient-centred care performance (r = 0.60, P < 0.001). The PCC scale was therefore determined to be a highly valid and reliable tool.

Considering quality of life for children with cancer: a systematic review of patient-reported outcome measures and the development of a conceptual model

OBJECTIVES

An appraisal of pediatric cancer-specific quality-of-life (QOL) instruments revealed a lack of clarity about what constitutes QOL in this population. This study addresses this concern by identifying the concepts that underpin the construct of QOL as determined by a content analysis of all patient-reported outcome (PRO) instruments used in childhood cancer research.

METHODS

A systematic review was performed of key databases (i.e., MEDLINE, CINAHL, PsychINFO) to identify studies of QOL in children with cancer. A content analysis process was used to code and categorize all items from generic and cancer-specified PRO instruments. Our objective was to provide clarification regarding the conceptual underpinnings of these instruments, as well as to help inform the development of theory and contribute to building a conceptual framework of QOL for children with cancer.

RESULTS

A total of 6,013 English language articles were screened, identifying 148 studies. Ten generic and ten cancer-specific PRO instruments provided 957 items. Content analysis led to the identification of four major domains of QOL (physical, psychological, social, and general health), with 11 subdomains covering 98 different concepts. While all instruments reflected items relating to the broader domains of QOL, there was substantial heterogeneity in terms of the content and variability in the distribution of items.

CONCLUSIONS

This systematic review and the proposed model represent a useful starting point in the critical appraisal of the conceptual underpinnings of PRO instruments used in pediatric oncology and contribute to the need to place such tools under a critical, yet reflective and analytical lens.

Does school attendance during initial cancer treatment in childhood increase the risk of infection?

BACKGROUND

The present study aimed to investigate the relationship between school attendance and infection requiring antimicrobial treatment in children undergoing treatment for cancer.

PROCEDURE

A national cohort of children aged 7-16 years undergoing cancer treatment was assessed during two observation periods of 19 days each, 1 month (n = 89) and 2.5 months (n = 89) poststart of treatment. Children free from infection at start of each observation period were included. Multivariable logistic regression analyses were performed including factors potentially associated with start of antimicrobial treatment.

RESULTS

Twenty-seven (30%) children started antimicrobial treatment during the first observation period. Factors associated with an increased risk of starting antimicrobial treatment were diagnosed with sarcoma (OR = 24.37, P = 0.002) or non-Hodgkin lymphoma (OR = 17.57, P = 0.025), having neutropenia (OR = 5.92, P = 0.020) and age less than 13 years (OR = 8.54, P = 0.014). During the second observation period, when 20 (22%) children started antimicrobial treatment, the probability of starting treatment was increased in children with neutropenia (OR = 4.25, P = 0.007). There was no statistically significant association between starting treatment for infection and school attendance.

CONCLUSIONS

In this study, children attending school while undergoing cancer treatment did not run a higher risk of starting antimicrobial treatment than children absent from school. However, there is a need for further studies evaluating risk of infections in children with ongoing cancer treatment.

The Importance of General Self-Efficacy for the Quality of Life of Adolescents with Diabetes or Juvenile Rheumatoid Arthritis Over Time: A Longitudinal Study among Adolescents and Parents

PURPOSE

To (i) investigate the influence of general self-efficacy on quality of life outcomes over time among adolescents with type I diabetes or juvenile rheumatoid arthritis (JRA), (ii) investigate parents' perceptions of general self-efficacy and quality of life of adolescents with diabetes or JRA over time, and (iii) identify possible differences in the evaluations of adolescents and parents.

METHODS

This study included adolescents aged 12-25 years with type I diabetes or JRA and their parents. At T1, 171/573 (30% response rate) adolescents with diabetes or JRA and 229/563 (41% response rate) parents completed the questionnaire. At T2, 230/551 (42% response rate) adolescents and 220/559 (39% response rate) parents still participating in the study completed the questionnaire. A total of 112 adolescents and 143 parents filled in the questionnaires at both T1 and T2.

RESULTS

Adolescents perceived significant improvement in their general self-efficacy and reduced quality of life over time, whereas parents' perceptions did not change. According to adolescents and parents, physical functioning was better among adolescents with diabetes than among those with JRA. Regression analyses of adolescents' data showed that general self-efficacy at T1 (β = 0.13; p ≤ 0.10) and changes in general self-efficacy (β = 0.22; p ≤ 0.01) predicted quality of life at T2. Parents' responses revealed that adolescents' general self-efficacy at T1 (β = 0.16; p ≤ 0.05) and changes in adolescents' general self-efficacy (β = 0.18; p ≤ 0.05) predicted adolescents' quality of life at T2.

CONCLUSION

General self-efficacy and changes therein positively affected quality of life in adolescents with diabetes or JRA over time, as perceived by adolescents and parents. These findings emphasize the need for the implementation of interventions aiming to improve general self-efficacy in these populations.
