Purpose
The current longitudinal observational study aimed to explore how chronic pain among schoolchildren changed before and during the COVID-19 pandemic, and how changes in chronic pain were related to changes in psychological wellbeing and COVID-19-related experiences.
Methods
Data were collected from N = 777 German schoolchildren (aged 9–17 years) at two assessments before and one assessment during the COVID-19 pandemic lockdown. Participants self-reported chronic pain experience, anxiety, depression, and quality of life across all assessments; and COVID-19-related experiences at the last assessment. Trajectories of anxiety, depression, and quality of life as well as COVID-19-related experiences were analyzed separately for groups of stable chronic pain trajectories compared to chronic pain trajectories that changed during the pandemic.
Results
Chronic pain prevalence was lowest at the assessment during the COVID-19 pandemic (22.8% vs. 29.2% and 29.9% before the pandemic). However, 4.6% experienced new chronic pain onset during the COVID-19 pandemic. This was preceded by heightened depression and anxiety, as well as lowered quality of life scores. These students were also more likely to describe time with their family during the COVID-19 pandemic as tense compared to students who did not develop chronic pain. During the COVID-19 pandemic boys were more likely to recover from ongoing chronic pain than girls.
Conclusions
Overall, during the COVID-19 pandemic the prevalence of chronic pain decreased. However, stressful situations and pre-existing vulnerabilities in psychological wellbeing can facilitate the development of chronic pain during the pandemic.
Purpose
Fatigue is a common symptom in children and adolescents. Its negative impact on health outcomes is even more pronounced in those with chronic pain. There is currently no fatigue measurement tool in German that is validated for both children and adolescents with and without chronic pain. Therefore, this study aimed to gather quantitative validity evidence to support the use of the German version of the PROMIS® Pediatric Short Form v2.0 - Fatigue 10a (PROMIS® F-SF) in the German pediatric general population as well as in German pediatric chronic pain patients.
Methods
The 10-item self-assessment questionnaire was validated in a sample of N = 1348 school children (9–18 years; 52.4% female) and N = 114 pediatric chronic pain patients (8–17 years; 63.3% female). Construct and convergent validity, reliability, and item and scale characteristics were examined.
Results
Confirmatory factor analyses showed sufficient model fit for the 1-factor model of the questionnaire (school sample: CFI = 0.94, RMSEA = 0.10, SRMR = 0.04; patient sample: CFI = 0.90, RMSEA = 0.14, SRMR = 0.05). Convergent validity was supported by weak-to-large significant correlations with sleep quality, health-related quality of life (HRQoL), and pain characteristics. The questionnaire had excellent internal consistency in both samples (α = 0.92 and α = 0.93). Sex differences and age distributions of the PROMIS® F-SF showed that girls reported significantly higher fatigue than boys and that fatigue increased with age.
Conclusion
The PROMIS® F-SF is a reliable instrument with good psychometric properties. Preliminary evidence is provided that the questionnaire validly measures fatigue in children and adolescents with and without chronic pain.
