Content validity of a newly developed observer-reported measure for pediatric asthma in children aged 2-5 years.

BACKGROUND: An observer-reported outcome (ObsRO) measure assessing both symptom control and health-related quality of life (HRQoL) in children with asthma younger than 6 years is lacking. The objective of this study was to evaluate the content validity of the Pediatric Asthma Questionnaire (PAQ), a newly developed 6-item ObsRO measure for caregivers of children aged 2-5 years diagnosed with asthma. RESULTS: In-depth, qualitative interviews were conducted with 15 parents or caregivers. The first part of the interview was an open-ended discussion whereby participants were asked to describe their observations of their child's asthma symptoms and HRQoL impacts followed by a cognitive debriefing of a draft version of the PAQ. The most frequently reported symptoms were coughing (n = 15, 100%), wheezing (n = 14, 93%), and trouble breathing (n = 10, 67%). Overall, participants found the PAQ easy to complete and relevant to their child's experience with asthma, with most reporting the instructions, response scales, and recall period for the items to be appropriate. The majority of participants (93%) believed they could accurately report on the items included in the PAQ based on their observations of their child's asthma symptoms and impacts, or reliably get the information from the child's teacher, school, or caregiver when their child was not in their presence. One item was modified based on feedback about the phrase "oral steroids" to clarify modes of administration. A few other minor changes were incorporated into the PAQ following suggestions from participants, including replacing the phrase "how often" with "how many days" in one of the items to improve clarity and overall consistency with the response options. CONCLUSION: Qualitative data support the content validity of the PAQ as a fit-for-purpose and well-understood 6-item observer-reported outcome measure to evaluate both symptoms and asthma-specific HRQoL impacts experienced by pediatric asthma patients aged 2-5 years for use in clinical and real-world studies.

Patient-reported outcomes in paediatric cancer survivorship: a qualitative study to elicit the content from cancer survivors and caregivers.

OBJECTIVES: Content elucidation for patient-reported outcomes (PROs) in paediatric cancer survivorship is understudied. We aimed to compare differences in the contents of five PRO domains that are important to paediatric cancer survivorship through semistructured interviews with paediatric cancer survivors and caregivers, and identified new concepts that were not covered in the item banks of the Patient-Reported Outcomes Measurement Information System (PROMIS). DESIGN: Semistructured interviews to collect qualitative PRO data from survivors and caregivers. SETTING: A survivorship care clinic of a comprehensive cancer centre in the USA. PARTICIPANTS: The study included 51 survivors (<18 years old) and 35 caregivers who completed interviews between August and December 2016. Content experts coded the transcribed interviews into 'meaningful concepts' per PROMIS item concepts and identified new concepts per a consensus. Frequencies of meaningful concepts used by survivors and caregivers were compared by Wilcoxon rank-sum test. RESULTS: For pain and meaning and purpose, 'Hurt a lot' and 'Purpose in life' were top concepts for survivors and caregivers, respectively. For fatigue and psychological stress, 'Needed to sleep during the day'/'Trouble doing schoolwork' and 'Felt worried' were top concepts for survivors, and 'Felt tired' and 'Felt distress'/'Felt stressed' for caregivers. Survivors reported more physically relevant contents (eg, 'Hard to do sport/exercise'; 0.78 vs 0.23, p=0.007) for pain, fatigue and stress, whereas caregivers used more emotionally relevant concepts (eg, 'Too tired to enjoy things I like to do'; 0.31 vs 0.05, p=0.025). Both groups reported positive thoughts for meaning and purpose (eg, 'Have goals for myself'). One (psychological stress, meaning and purpose) to eleven (fatigue) new concepts were generated. CONCLUSIONS: Important PRO contents in the form of meaningful concepts raised by survivors and caregivers were different and new concepts emerged. PRO measures are warranted to include survivorship-specific items by accounting for the child's and the caregiver's viewpoints.

Establishing the content validity of PROMIS Pediatric pain interference, fatigue, sleep disturbance, and sleep-related impairment measures in children with chronic kidney disease and Crohn's disease.

BACKGROUND: PROMIS Pediatric patient-reported outcome measures were developed with children from the general population, and their content validity has not been established in children with chronic disease. This study was done to evaluate the content validity of the PROMIS Pediatric Pain Interference and Fatigue measures in children 8-17 years-old with Crohn's disease and the PROMIS Pediatric Fatigue, Sleep Disturbance, and Sleep-related Impairment measures for children 8-17 years-old with chronic kidney disease. METHODS: We conducted semi-structured interviews with individuals affected by Crohn's disease and chronic kidney disease. The interviews were done to elicit children's lived experiences of the PROMIS outcomes of interest. We used deductive content analysis to contrast the participants' reports of their symptoms and impacts on daily life with existing conceptual frameworks for the PROMIS measures, each of which was developed with input from children in the general population. RESULTS: On average, we elicited an average of 7 pain interference and 7 fatigue concepts from Crohn's disease participants (n = 37), while chronic kidney disease participants (n = 26) provided 9 concepts for fatigue, 4 for sleep disturbance, and 7 for sleep-related impairment. Concept saturation was achieved after 16-19 interviews across the four PROMIS measures. Children with these two chronic health conditions reported the same breadth and types of lived experiences as children from the development samples drawn from the general population. CONCLUSION: The study supports the content validity of several PROMIS Pediatric measures for children with Crohn's disease and chronic kidney disease. These findings provide evidence that PROMIS Pediatric measures, developed as universally relevant patient-reported outcomes, may be more broadly applicable to children with chronic disease.

Importance ratings on patient-reported outcome items for survivorship care: comparison between pediatric cancer survivors, parents, and clinicians.

PURPOSE: To compare importance ratings of patient-reported outcomes (PROs) items from the viewpoints of childhood cancer survivors, parents, and clinicians for further developing short-forms to use in survivorship care. METHODS: 101 cancer survivors, 101 their parents, and 36 clinicians were recruited from St. Jude Children's Research Hospital. Participants were asked to select eight items that they deemed useful for clinical decision making from each of the four Patient-Reported Outcomes Measurement Information System Pediatric item banks. These item banks were pain interference (20 items), fatigue (23 items), psychological stress (19 items), and positive affect (37 items). RESULTS: Compared to survivors, clinicians rated more items across four domains that were statistically different than did parents (23 vs. 13 items). Clinicians rated five items in pain interference domain (ORs 2.33-6.01; p's < 0.05) and three items in fatigue domain (ORs 2.22-3.80; p's < .05) as more important but rated three items in psychological stress domain (ORs 0.14-0.42; p's < .05) and six items in positive affect domain (ORs 0.17-0.35; p's < .05) as less important than did survivors. In contrast, parents rated seven items in positive affect domain (ORs 0.25-0.47; p's < .05) as less important than did survivors. CONCLUSIONS: Survivors, parents, and clinicians viewed importance of PRO items for survivorship care differently. These perspectives should be used to assist the development of PROs tools.
