Children's self reported discomforts as participants in clinical research

Validity and reliability of the Swedish version of the Visual CARE Measure for assessing children's perceptions of nurses' empathy

The purpose of this study was to translate and validate a questionnaire to be used by children with chronic diseases during procedures. Specific research questions were as follows: Is the translated versions reliable? Is there a correlation between VCM and another questionnaire measuring discomfort to enhance the validity of VCM? The three versions of Visual CARE measure (VCM) were translated following the principles of good practice for translation and cultural adaptation of patient-reported outcome measures, according to the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Cognitive debriefing interviews with children, parents, and healthcare professionals were carried out. The correlation between empathy and discomfort was evaluated using DISCO-RC. The final versions of VCM were administered to children and their parents after a needle procedure or a nasal tube insertion. The Cronbach's alpha was 0.89 for the 5Q version, 0.93 for the 10Q version, and 0.96 for the 10Q-Parent version, which implies high internal consistency. The intra-class correlation was 0.623 for VCM 5Q, with a mean difference of 1.35 and an ICC of 0.767 for VCM 10Q, with a mean difference of 1.17. This is considered a good agreement between children's and their parents' assessments. A significant difference in the children's reports could be seen when experiencing high discomfort as opposed to low discomfort.

CONCLUSION

VCM is a useful Patient-Reported Experience Measure (PREM) that can help enhance the quality of care for children in a paediatric setting by capturing their perception of the empathy shown.

WHAT IS KNOWN

• Parents' by-proxy reports are not always aligned with children's self-reports. In healthcare situations, children can be hurt when they are ignored. • Research shows that empathic encounters relieve distress, improve the relationship between the patient (who could be a child) and carer, and create an open, trusting relationship.

WHAT IS NEW

• This study shows that all three versions of the Visual CARE Measure are valid for assessing children's experience of empathy shown by nurses during a procedure.. • This is one of the first studies that confirms the correlation between children's experience of nurses' levels of empathy and the child's discomfort. • This study shows that the Visual CARE Measure can support the evaluation of children's rights with regards to communication in a clinical context.

Factors influencing malnutrition among adolescent girls in The Gambia: a mixed-methods exploratory study

BACKGROUND

In The Gambia, existing research to understand and address malnutrition among adolescent girls is limited. Prior to the conduct of large-scale studies, formative research is needed. The aim of this mixed methods, cross-sectional study was to explore cultural contexts relevant to nutritional status, feasibility and appropriateness of recruitment and data collection methods (questionnaires and anthropometric measures), and plausibility of data collected.

METHODS

The study took place in May-June 2021 in an urban conurbation in Brikama local government area (LGA) and two rural villages in Mansakonko LGA, The Gambia. The purposive sampling frame of the all-female sample included residence in the selected urban or rural settings and being aged 10-14 or 15-19 years. Thirty-two girls aged 10 to 19 years, with equal numbers in urban and rural settings were recruited. Four focus groups discussions (FGDs), with eight participants in each, were held to understand perspectives on cultural practices; concepts of under- and overweight, and research recruitment methods. The same participants completed questionnaires on socioeconomic circumstances, health, access to community resources, nutrition knowledge, sleep, and physical activity, and had anthropometric measures taken. FGDs were then reconvened to discuss the feasibility and acceptability of the questionnaires and anthropometric measures, and views on providing biological samples in the future. FGD data were analysed using thematic analysis. Body mass index (BMI)-for-age and height-for-age z-scores, mid-upper arm circumference, and waist: hip ratios were assessed and descriptive statistics used to explore the data obtained.

RESULTS

Five themes were identified in the focus group discussions: 1. Cultural norms: harmful vs. beneficial to nutrition-related health; 2. Concepts of healthy diet and weight; 3. Approaches to tackling under- and overnutrition; 4. Study recruitment: barriers and facilitators; 5. Study questionnaires and proposed measures are mostly feasible and acceptable. Questionnaire data highlighted limited access to resources (e.g. food markets and electricity) as important individual, household and community factors influencing malnutrition in rural settings. The anthropometric measures reflected the double burden of malnutrition in The Gambia, with the presence of stunting (41%), underweight (31%), and living with overweight or obesity (10%). A higher proportion of participants were underweight in rural compared to urban settings (50% vs 12.5% respectively, p = 0.03). Over 70% of those classified as underweight perceived their weight as normal.

CONCLUSION

This exploratory study provides novel data to inform larger-scale research to understand and address malnutrition among adolescent females in The Gambia. Urban-rural variance in the double burden of malnutrition, factors influencing malnutrition, and in the barriers to and facilitators of adolescents taking part in research, are key considerations.

A Mixed Method Study in Young Children Participating in Clinical Research During A Kidney Transplantation Trajectory

INTRODUCTION

Regulations designed to protect children participating in clinical research often restrict the availability of research data necessary for the development of age-specific therapies and drug dosing. Few data exist on how children experience participation in clinical research, and studies investigating young children undergoing an intensive medical treatment are lacking.

METHODS

Mixed methods with semi-structured interviews and DISCO-RC questionnaires were used to explore young children's and their parents' experiences in clinical research participation during a kidney transplantation trajectory.

FINDINGS

Nine children and their parents were interviewed. Children's median age at kidney transplantation was 4 years (IQR 4,7); age at interview was 7 years (IQR 6,9). Thematic content analysis of interviews revealed that most children were unaware of having participated in a study. Both children and their parents frequently were unaware whether procedures were standard care or research related. The additional burden attributed to study participation varied from not at all to heavy in combination with intensive medical treatment. Positive experiences included kind healthcare professionals, effective distraction techniques, educational aspects, contributing to science and extra check-ups. Most reported negative experiences were conflicting communication, spending much time in the hospital, missing school and suboptimal planning. Venous puncture was stressful for all children, whereas the discomfort of other procedures varied.

CONCLUSION

Pediatric clinical research design should focus on education and fun during research procedures, smart planning, consistent communication, close collaboration between clinical and research team and age appropriate distraction techniques.

Children's satisfaction with a comprehensive study program-Results from the LIFE Child cohort study

BACKGROUND

Research participants' satisfaction is a topic of great interest, especially in the context of longitudinal studies. Evaluation also represents an important component of quality management in the health care system. Adult studies found that personal characteristics, e.g., age, sex, ethnicity, and SES, can influence satisfaction with health care or study participation. Studies on paediatric participants are sparse.

OBJECTIVES

To examine how children rated the study day of a cohort study and how these ratings were associated with sociodemographic and socioeconomic characteristics and retention in the context of a large cohort study.

METHODS

Analyses were performed on 4- to 17-year-old participants of the German longitudinal cohort study LIFE Child (n = 2033). To assess the associations between overall satisfaction (high versus low/middle) and age, sex, body-mass index, socioecomonic status, and participation in a follow-up visit, we applied logistic mixed-effects models.

RESULTS

Participants' overall satisfaction with the LIFE Child study day was high ("very good": 67.8%). Overall satisfaction was higher in 7-9 years olds (odds ratio [OR] 2.00, 95% confidence interval [CI 1.51, 2.66) and 10-12 years olds (OR 1.51, 95% CI 1.16, 1.98) than in 4-6 years olds and 13-17 years olds. Children with obesity were less likely to participate in a follow-up visit (OR 0.56, 95% CI 0.39, 0.78). Children reporting high overall satisfaction at the first study visit completed a follow-up visit more frequently (OR 1.32, 95% CI 1.05,1.67).

CONCLUSIONS

A high level of satisfaction increased participants' attendance at a follow-up visit. Our results might be helpful for adapting the study program to the participants' needs in order to maximise retention and minimise attrition rates.

'Scanxiety': Content analysis of pre-MRI patient experience on Instagram

INTRODUCTION

Distress and anxiety are commonly reported during the Magnetic Resonance Imaging (MRI) experience with prior studies suggesting the pre-MRI period is a time of heightened distress. There is a paucity of literature exploring preprocedural distress and anxiety, in particular qualitative research analysing patient experience. Instagram is rapidly becoming an important social media platform though which to conduct health research. A gradually increasing number of studies have examined social media to gain insight into patient experience within medical radiation science (MRS). This study is considered as the first to explore patient experience of MRI using Instagram as a data source.

METHODS

This study investigated the patient experience during the pre-MRI period by performing a content analysis on open-source Instagram posts. Ethical approval for the study was sought and approved by the Charles Sturt University, Human Research Ethics Committee.

RESULTS

Six themes emerged from the extracted data; Journey to the MRI, Waiting, Anticipating the MRI procedure, Preparing for the MRI procedure, Negative interaction, and Fear of the results.

CONCLUSION

The findings of this study provide novel self-reported and unsolicited insight into the diverse, multifactorial, and often concomitant nature of preprocedural MRI anxiety and distress.

IMPLICATIONS FOR PRACTICE

This study adds to a growing body of literature advocating for a compassionate, holistic, and person-centered approach when caring for patients in MRI that also considers their emotional and psychological wellbeing.

Paediatric eye and vision research participation experiences: a systematic review

BACKGROUND

For children and young people with eye and vision conditions, research is essential to advancing evidence-based recommendations in diagnosis, prevention, treatments and cures. Patient 'experience' reflects a key measure of quality in health care (Department of Health. High Quality Care for All: NHS Next Stage Review Final Report: The Stationery Office (2008)); research participant 'experiences' are equally important. Therefore, in order to achieve child-centred, high-quality paediatric ophthalmic research, we need to understand participation experiences. We conducted a systematic review of existing literature; our primary outcome was to understand what children and young people, parents and research staff perceive to support or hinder positive paediatric eye and vision research experiences. Our secondary outcomes explored whether any adverse or positive effects were perceived to be related to participation experiences, and if any interventions to improve paediatric ophthalmic research experiences had previously been developed or used.

METHODS

We searched (from inception to November 2018, updated July 2020) in MEDLINE, Embase, CINAHL, Web of Science, NICE evidence and The Cochrane Library (CDSR and CENTRAL), key journals (by hand), grey literature databases and Google Scholar; looking for evidence from the perspectives of children, young people, parents and staff with experience of paediatric ophthalmic research. The National Institute for Health Research (NIHR) Participant in Research Experience Survey (PRES) (National Institute for Health Research. Research Participant Experience Survey Report 2018-19 (2019); National Institute for Health Research. Optimising the Participant in Research Experience Checklist (2019)) identified 'five domains' pivotal to shaping positive research experiences; we used these domains as an 'a priori' framework to conduct a 'best fit' synthesis (Carroll et al., BMC Med Res Methodol. 11:29, 2011; Carroll et al., BMC Med Res Methodol. 13:37, 2013).

RESULTS

Our search yielded 13,020 papers; two studies were eligible. These evaluated research experiences from the perspectives of parents and staff; the perspectives of children and young people themselves were not collected. No studies were identified addressing our secondary objectives. Synthesis confirmed the experiences of parents were shaped by staff characteristics, information provision, trial organisation and personal motivations, concurring with the 'PRES domains' (National Institute for Health Research. Optimising the Participant in Research Experience Checklist (2019)) and generating additional dimensions to participation motivations and the physical and emotional costs of study organisation.

CONCLUSIONS

The evidence base is limited and importantly omits the voices of children and young people. Further research, involving children and young people, is necessary to better understand the research experiences of this population, and so inform quality improvements for paediatric ophthalmic research care and outcomes.

Consent to research participation: understanding and motivation among German pupils

Background

The EU’s 2006 Paediatric Regulation aims to support authorisation of medicine for children, thus effectively increasing paediatric research. It is ethically imperative to simultaneously establish procedures that protect children’s rights.

Method

This study endeavours (a) to evaluate whether a template consent form designed by the Standing Working Group of the German-Research-Ethics-Committees (AKEK) adequately informs adolescents about research participation, and (b) to investigate associated phenomena like therapeutic misconception and motives for research participation. In March 2016 a questionnaire study was conducted among 279 pupils (mean age 13.1 years) of a secondary school in northern Germany.

Results

A majority of participants showed a general good understanding of foundational research ethics concepts as understood from the AKEK consent form. Nevertheless, our data also suggests possible susceptibility to therapeutic misconception. Own health concerns and pro-social considerations were found to be significant motivational factors for participating in research, while anticipation of pain lessens likelihood of participation. Advice from trusted others is an important decisional influence, too. Furthermore, data security was found to be a relevant aspect of adolescents’ decision-making process.

Conclusion

Bearing in mind adolescents’ generally good understanding, we infer the lack of knowledge about medical research in general to be one source of therapeutic misconception. To further improve the quality of consent we propose a multi-staged approach whereby general research education is completed before an individual becomes a patient or potential participant. To the best of our knowledge this is the first German questionnaire-study addressing issues of informed consent in a large under-age sample.

How to Maximize Children's Involvement in Non-therapeutic Research-Lessons Learnt From EFFECTOR

Background: Children are vulnerable study subjects, especially in non-therapeutic research. Nowadays more attention is paid to the children's voice in both decision-making on participation and their experience of clinical research procedures. Methods: We share our experiences from a long-term, cross-sectional, non-therapeutic follow-up study in the offspring of mothers who participated in scientific research during their pregnancy. Results: During the data collection process, different strategies were developed to achieve a satisfactory participation rate with a focus on the involvement of the children. All study documents and measurements were assembled into a superhero framework. This theme is flexible and attracts children of a wide age-span. In order to inform the children before the study visit, a visually attractive assent was created as well as a superhero video. During the study visit, a sticker diploma was used with similar visuals from the assent. The toddlers received a superhero-cape. The children were involved in the decision-making process during the whole process. Discussion and conclusion: From our experience during the EFFECTOR data collection process, parents and their children can be motivated to participate in a long-term, non-therapeutic, follow-up study when child friendly and adequate communication is used. Framing in a superhero theme is simple and suitable for children of a wide age-span.

A comparison study of anxiety in children undergoing brain MRI vs adults undergoing brain MRI vs children undergoing an electroencephalogram

Background

Magnetic resonance imaging (MRI) of the brain in children and adolescents is a well-established method in both clinical practice and in neuroscientific research. This practice is sometimes viewed critically, as MRI scans might expose minors (e.g. through scan-associated fears) to more than the legally permissible “minimal burden”. While there is evidence that a significant portion of adults undergoing brain MRI scans experience anxiety, data on anxiety in children and adolescents undergoing brain MRI scans is rare. This study therefore aimed to examine the prevalence and level of anxiety in children and adolescents who had MRI scans of the brain, and to compare the results to adults undergoing brain MRI scans, and to children and adolescents undergoing electroencephalography (EEG; which is usually regarded a “minimal burden”).

Method

Participants were 57 children and adolescents who had a brain MRI scan (MRI-C; mean age 12.9 years), 28 adults who had a brain MRI scan (MRI-A; mean age 43.7 years), and 66 children and adolescents undergoing EEG (EEG-C; mean age 12.9 years). Anxiety was assessed on the subjective (situational anxiety) and on the physiological level (arousal), before and after the respective examination.

Results

More than 98% of children and adolescents reported no or only minimal fear during the MRI scan. Both pre- and post-examination, the MRI-C and the MRI-A groups did not differ significantly with respect to situational anxiety (p = 0.262 and p = 0.374, respectively), and to physiological arousal (p = 0.050, p = 0.472). Between the MRI-C and the EEG-C group, there were also no significant differences in terms of situational anxiety (p = 0.525, p = 0.875), or physiological arousal (p = 0.535, p = 0.189). Prior MRI experience did not significantly influence subjective or physiological anxiety parameters.

Conclusions

In this study, children and adolescents undergoing a brain MRI scan did not experience significantly more anxiety than those undergoing an EEG, or adults undergoing MRI scanning. Therefore, a general exclusion of minors from MRI research studies does not appear reasonable.

Young children experience little emotional burden during invasive procedures in asthma research

Research in children should strike the right balance between protecting underage study subjects and advancing the medical field. This study gives insight into the emotional burden that common invasive research procedures in asthma research have on young children, both from the child and parent perspective. Puppetry was used to stimulate children (age 5-6 years) to explain their emotional burden prior to and after the research procedures. We operationalised emotional burden as willingness to participate in future research and reluctance towards participation. Parents filled out a questionnaire on this topic. Symptomatic patients as well as healthy controls were analysed. Forty-one children were included. Children's anticipatory fear for future research showed a clear decrease of 0.7 ± 1.6 on a 5-point Likert scale as a consequence of participation (p = 0.02). Sixty percent of all participating children explicitly indicated willingness to undergo identical research procedures again. Children uninformed by their parents about the venipuncture were significantly more reluctant to the venipuncture after the procedure (p < 0.01), compared to children who had been informed (4.0 ± 0.9 resp. 2.8 ± 1.2).Conclusion: This study suggests that the emotional burden of participation in asthma research for underage children can be prevented when they are properly informed and decreases as a consequence of participations. We believe increased emphasis should be placed on informing children and evaluating the emotional impact of research to help caretakers and research ethics committees make informed decisions about participation of children in medical research. What is Known: • Medical professionals and parents are likely to overestimate children's discomfort undergoing (invasive) research procedures. • Two thirds of children (age 6-18 years) participating in medical research indicated that they would participate in the same research study again. What is New: • Pre-school children experience little emotional burden during invasive procedures in asthma research. • Proper communication about (invasive) research procedures in pre-school children helps to reduce the anticipatory fear of these procedures in the future.

Conducting evaluation research with children exposed to violence: How technological innovations in methodologies and data collection may enhance the process

Research and program evaluation processes that engage children and youth are becoming much more common due to influences from children's rights and the acknowledgement that children have the capacity to contribute to research, both as participants and co-researchers (Roberts, 2017). Recent technological advances in the form of tablet and internet-based applications have provided researchers with additional methodological tools to better capture the voices and experiences of children and their caregivers (Livingstone & Blum-Ross, 2017). However, little has been written on the ways in which these new technological advances can improve research experiences for children who have been exposed to intimate partner and family violence, as well as other forms of traumatic experiences. This paper provides a review of current literature and a case study example of how one children's mental health agency has implemented tablet-based data collection procedures.

The development of the DISCO-RC for measuring children's discomfort during research procedures

BACKGROUND

There is a need for data on children's self-reported discomfort in clinical research, helping ethics committees to make their evaluation of discomfort described in study protocols evidence-based. Since there is no appropriate instrument to measure children's discomfort during medical research procedures, we aimed to develop a generic, short and child-friendly instrument: the DISCO-RC questionnaire (DISCOmfort in Research with Children).

METHODS

This article describes the six steps of the development of the DISCO-RC. First, we updated a literature search on children's self-reported discomfort in clinical research to get insight in what words are used to measure discomfort (step 1). Subsequently, we interviewed 46 children (6-18 years) participating in research to get insight into important forms of discomfort for children (step 2), and asked them about their preferred response option for measuring discomfort (step 3). Next, we consulted nine paediatric research professionals from various backgrounds for input on the content and feasibility of the DISCO-RC (step 4). Based on the previous steps, we developed a draft version of the DISCO-RC, which we discussed with the professionals. The DISCO-RC was then pretested in 25 children to ensure face-validity from the child's perspective and feasibility (step 5). Finally, validity, reliability and internal consistency were tested (step 6).

RESULTS

The search-update revealed several words used for measuring discomfort in research (e.g. 'worries', 'unpleasantness'). The interviews gave insight into important forms of discomfort for children in research (e.g. 'pain', 'boredom'). Children preferred a 5-point Likert scale as response option for the DISCO-RC. The experts recommended a short, digital instrument involving different forms of discomfort, and measuring discomfort of individual research procedures. Pretesting of the DISCO-RC resulted in a few layout changes, and feedback from the children confirmed the feasibility of the DISCO-RC. Convergent validity and test-retest reliability were acceptable. Internal consistency based on item-rest correlations and Cronbach's alpha were low, as expected.

CONCLUSIONS

The DISCO-RC is a generic, practical and psychometrically sound instrument for measuring children's discomfort during research procedures. It contributes to make the evaluation of discomfort in paediatric research evidence-based. Therefore, we recommend including the DISCO-RC as standard component of paediatric research studies.

The child's perspective on discomfort during medical research procedures: a descriptive study

OBJECTIVE

The evaluation of discomfort in paediatric research is scarcely evidence-based. In this study, we make a start in describing children's self-reported discomfort during common medical research procedures and compare this with discomfort during dental check-ups which can be considered as a reference level of a 'minimal discomfort' medical procedure. We exploratory study whether there are associations between age, anxiety-proneness, gender, medical condition, previous experiences and discomfort. We also describe children's suggestions for reducing discomfort.

DESIGN

Cross-sectional descriptive study.

SETTING

Paediatric research at three academic hospitals.

PATIENTS

357 children with and without illnesses (8-18 years, mean=10.6 years) were enrolled: 307 from paediatric research studies and 50 from dental care.

MAIN OUTCOME MEASURES

We measured various generic forms of discomfort (nervousness, annoyance, pain, fright, boredom, tiredness) due to six common research procedures: buccal swabs, MRI scans, pulmonary function tests, skin prick tests, ultrasound imaging and venepunctures.

RESULTS

Most children reported limited discomfort during the research procedures (means: 1-2.6 on a scale from 1 to 5). Compared with dental check-ups, buccal swab tests, skin prick tests and ultrasound imaging were less discomforting, while MRI scans, venepunctures and pulmonary function tests caused a similar degree of discomfort. 60.3% of the children suggested providing distraction by showing movies to reduce discomfort. The exploratory analyses suggested a positive association between anxiety-proneness and discomfort.

CONCLUSIONS

The findings of this study support the acceptability of participation of children in the studied research procedures, which stimulates evidence-based research practice. Furthermore, the present study can be considered as a first step in providing benchmarks for discomfort of procedures in paediatric research.

Are positive experiences of children in non-therapeutic research justifiable research benefits?

BACKGROUND

Conducting non-therapeutic research is ethically challenging because participation conveys risks and burden and no health benefit. In this paper, we report the positive experiences of a diverse group of healthy and ill children (6-18 years) who participated in non-therapeutic research studies and discuss whether these positive experiences can justifiably be viewed as benefits.

METHODS

We used semistructured interviews from an earlier study about children's experiences in clinical research and did a secondary analysis on the positive experiences of the children in the non-therapeutic studies (N=30). Interviews were analysed using 'thematic' analysis.

RESULTS

The interviewed children most frequently mentioned as positive experiences of non-therapeutic research participation helping others and the gratification that comes with it, possible health benefits in the future, having fun and new/increased knowledge about the human body, hospitals and doing research. Less frequently mentioned were getting a present, not having to go to school and getting extra attention from healthcare staff.

CONCLUSIONS

Our study shows that children participating in non-therapeutic research have various positive experiences while taking part. We argue that some of these justifiably could be taken into the risk-benefit analysis in certain situations or maybe even as a standard part of this analysis. This may help to increase the number of (crucial) non-therapeutic studies with children.

To stop or not to stop: dissent and undue burden as reasons to stop participation in paediatric research

Children participating in clinical research may show signs of discomfort, discontent, dissent and so on, that cannot be solved by comforting the child. When, and on what ground, should such signs lead to the decision to withdraw the child from the trial? In order to adequately protect children participating in clinical research, it is important to know how to determine during the course of a trial whether participation is still justified. Yet to date, legislation, ethical guidelines and medical ethical literature do not provide sufficient guidance. Therefore, in this paper we aim to provide the required clarity. We identify two types of reasons for taking signs of discomfort, discontent, dissent and so on, very seriously: (1) the principle of respect for the growing autonomy of the child, in those cases where a child expresses a clear, explicit and persistent wish to be withdrawn from the study; and (2) the principle of non-maleficence, in those cases where for an individual child, the research burden appears to be higher than acceptable. We recommend to closely monitor each child during the course of the study, thereby being vigilant to whether the child still wants to continue and to whether the actual burden the child experiences is still acceptable in relation to the permitted levels of burden.

Association of diabetes mellitus and structural changes in the central nervous system in children and adolescents: a systematic review

Background

The relationship between diabetes and academic performance have been of great interest to researchers during the year to date. Many studies have been conducted to discover this relationship during three recent decades. But, evaluation of the structural changes of brain in the context of diabetes is of paramount importance especially in children and adolescents.

Methods

This study is a systematic review conducted to investigate the structural changes in the central nervous system in children and adolescents living with diabetes. Among about 500 papers published in this area in Pubmed and SCOPUS, 13 articles in the field of assessing structural changes in the central nervous system in children and adolescents with diabetes mellitus were entered into the evaluation process.

Results

As can be seen in these studies, a huge proportion of structures of the central nervous system have been affected by diabetes that include different areas of gray and white matters. In the majority of these studies, it has become clear that high glycemic changes, especially recurrent hyperglycemic attacks are very seriously associated with structural changes in the brain.

Conclusion

It seems the findings of this review can positively aid other researchers to develop medical guidelines to prevent or resolve the brain changes in central nervous structure and consequently cognitive impairments in children and adolescents.
