Purpose During the COVID-19 pandemic in the Netherlands, governmental regulations resulted in a lockdown for adults as well as children/adolescents. Schools were closed and contact with other people was limited. In this cross-sectional, population-based study, we aimed to investigate the mental/social health of children/adolescents during COVID-19 lockdown. Methods Two representative samples of Dutch children/adolescents (8–18 years) before COVID-19 (2018, N = 2401) and during lockdown (April 2020, N = 844) were compared on the Patient-Reported Outcomes Measurement Information System (PROMIS) domains: global health, peer relationships, anxiety, depressive symptoms, anger, sleep-related impairment by linear mixed models and calculating relative risks (RR (95% CI)) for the proportion of severe scores. Variables associated with worse mental/social health during COVID-19 were explored through multivariable regression models. The impact of COVID-19 regulations on the daily life of children was qualitatively analyzed. Results Participants reported worse PROMIS T-scores on all domains during COVID-19 lockdown compared to before (absolute mean difference range 2.1–7.1 (95% CI 1.3–7.9). During lockdown, more children reported severe Anxiety (RR = 1.95 (1.55–2.46) and Sleep-Related Impairment (RR = 1.89 (1.29–2.78) and fewer children reported poor Global Health (RR = 0.36 (0.20–0.65)). Associated factors with worse mental/social health were single-parent family, ≥ three children in the family, negative change in work situation of parents due to COVID-19 regulations, and a relative/friend infected with COVID-19. A large majority (> 90%) reported a negative impact of the COVID-19 regulations on daily life. Conclusion This study showed that governmental regulations regarding lockdown pose a serious mental/social health threat on children/adolescents that should be brought to the forefront of political decision-making and mental healthcare policy, intervention, and prevention.

Importance: It is unknown how a lockdown during the COVID-19 pandemic impacts childrens and adolescents mental and social health. Objective: To compare mental and social health of children and adolescents during the COVID-19 lockdown versus before, identify associated factors, describe the change in atmosphere at home and qualitatively assess the impact of COVID-19 regulations on daily life. Design: Cross-sectional study comparing two Dutch representative samples of children and adolescents (8-18 years); before COVID-19 (Dec2017-July2018) and during the COVID-19 lockdown (April/May 2020). Setting: Population-based Participants: Children and adolescents aged 8-18 years (M=13.4, 47.4% male), representative of the Dutch population on key demographics. Exposure(s): COVID-19 pandemic lockdown Main Outcome(s) and Measure(s): Patient-Reported Outcomes Measurement Information System (PROMIS) domains: Global Health, Peer Relationships, Anxiety, Depressive Symptoms, Anger and Sleep-Related Impairment. Single item on atmosphere at home and open question regarding the impact of the regulations on the childs/adolescents daily life Results: Children and adolescents reported significantly worse PROMIS T-scores on all domains (absolute mean difference range, 2.1-7.1; absolute 95% CI range, 1.3-7.9) during the COVID-19 lockdown as compared to before COVID-19. More children reported severe Anxiety (during 16.7% vs. before 8.6%; relative risk 1.95; 95% CI 1.55-2.46) and Sleep-Related Impairment (during 11.5% vs. before 6.1%; relative risk 1.89; 95% CI 1.29-2.78). Fewer children reported poor Global Health (during 1.7 vs. before 4.6%; relative risk 0.36; 95% CI 0.20-0.65). More mental and social health complaints during the COVID-19 lockdown were found in children and adolescents growing up in a single-parent family, having >three children in the family, a negative change in work situation of parents due to COVID-19 regulations, and having a relative/friend infected with COVID-19. A small effect was found on atmosphere at home during the lockdown compared to before (mean difference, -3.1; 95% CI, -4.1 - -2.1). A large majority (>90%) reported a negative impact of the COVID-19 regulations on their daily life. Conclusions and Relevance: This study showed that governmental regulations regarding lockdown pose a serious mental and social health threat on children and adolescents that should be brought to the forefront of political decision making and mental health care policy, intervention and prevention.

Purpose Since 2011, the evidence-based KLIK Patient Reported Outcome Measure (PROM) portal has been implemented in clinical practice in > 20 Dutch hospitals. Patients and/or parents complete PROMs on Health Related Quality of Life, symptoms and psychosocial functioning before their outpatient consultation. Answers are converted into an ePROfile and discussed by clinicians during consultation to monitor well-being over time and detect problems early. This study aims to get insight into the KLIK implementation from the clinician’s perspective. Methods As part of the KLIK implementation process, annual meetings were held with multidisciplinary teams to evaluate the use of KLIK. An online questionnaire was sent regarding (1) overall satisfaction, (2) feeling competent to discuss PROMs, (3) use of KLIK during the consultation, (4) influence of KLIK on the consultation, (5) usability of the KLIK PROM portal, (6) satisfaction with PROMs and feedback, and (7) support of the KLIK expert team. Open questions about (dis)advantages were included. Descriptive analyses were used. Results One hundred and forty-eight clinicians (response-rate 61%) from 14 hospitals in the Netherlands participated. Results show that: (1) clinicians report an overall satisfaction of median = 69/100 (visual analogue scale), (2) 85.8% feel competent discussing the ePROfile, (3) 70.3% (almost) always discuss the ePROfile, (4) 70.3% think that KLIK improves consultation, (5) 71.6% think KLIK is easy to use, (6) 80.4% are satisfied with the feedback of the overall KLIK ePROfile, (7) 71.6% experience sufficient support of the KLIK team. Conclusion Participating clinicians are generally satisfied with KLIK. Improvements to the KLIK PROM portal are now realized based on the mentioned disadvantages (e.g., shorten PROM completion by use of PROMIS and integrating KLIK with Electronic Health Records).

The aim of the study was to assess internalizing problems before and during the pandemic with data from Dutch consortium Child and adolescent mental health and wellbeing in times of the COVID-19 pandemic, consisting of two Dutch general population samples (GS) and two clinical samples (CS) referred to youth/psychiatric care. Measures of internalizing problems were obtained from ongoing data collections pre-pandemic (NGS = 35,357; NCS = 4487) and twice during the pandemic, in Apr–May 2020 (NGS = 3938; clinical: NCS = 1008) and in Nov–Dec 2020 (NGS = 1489; NCS = 1536), in children and adolescents (8–18 years) with parent (Brief Problem Monitor) and/or child reports (Patient-Reported Outcomes Measurement Information System®). Results show that, in the general population, internalizing problems were higher during the first peak of the pandemic compared to pre-pandemic based on both child and parent reports. Yet, over the course of the pandemic, on both child and parent reports, similar or lower levels of internalizing problems were observed. Children in the clinical population reported more internalizing symptoms over the course of the pandemic while parents did not report differences in internalizing symptoms from pre-pandemic to the first peak of the pandemic nor over the course of the pandemic. Overall, the findings indicate that children and adolescents of both the general and clinical population were affected negatively by the pandemic in terms of their internalizing problems. Attention is therefore warranted to investigate long-term effects and to monitor if internalizing problems return to pre-pandemic levels or if they remain elevated post-pandemic.

Aim To compare Health‐Related Quality of Life (HRQOL) of paediatric patients with newly collected HRQOL data of the general Dutch population, explore responses to individual items and investigate variables associated with HRQOL. Methods Children (8–12y) and adolescents (13–17y) from the general population (N = 966) and from a paediatric population (N = 1209) completed the Pediatric Quality of Life Inventory (PedsQLTM) online via the KLIK Patient‐Reported Outcome Measures portal. PedsQLTM scale scores were compared between groups with independent t tests, by age group and gender. Responses to PedsQLTM items were explored using descriptive analyses. Linear regression analyses were performed to determine which variables were associated with HRQOL. Results Paediatric patients reported worse HRQOL than the general population on all PedsQLTM scales (p ≤ .001, d = 0.20–1.03), except social functioning, and a high proportion reported problems on PedsQLTM items, for example, ‘I have trouble sleeping’. Younger age, female gender and school absence were negatively associated with HRQOL (β = −0.37–0.10, p ≤ .008). Conclusion Paediatric patients reported lower HRQOL than the general population, and school absence, female gender and younger age were associated with lower HRQOL. The results underline the importance to structurally monitor paediatric patients’ HRQOL in clinical practice to detect problems and offer the right help on time.

Background: The COVID-19 lockdown increases psychological problems in children and adolescents from the general population. Here we investigate the mental and social health during the COVID-19 lockdown in children and adolescents with pre-existing mental or somatic problems.Methods: We included participants (8–18 years) from a psychiatric (N = 249) and pediatric (N = 90) sample, and compared them to a general population sample (N = 844). Measures were assessed during the first lockdown (April-May 2020) in the Netherlands. Main outcome measures were Patient-Reported Outcomes Measurement Information System (PROMIS®) domains: Global Health, Peer Relationships, Anxiety, Depressive Symptoms, Anger, and Sleep-Related Impairment, as reported by children and youth. Additionally, socio-demographic variables, COVID-19-related questions, changes in atmosphere at home from a parent and child perspective, and children's experiences of lockdown regulations were reported by parents.Results: On all measures except Global Health, the pediatric sample reported least problems. The psychiatric sample reported significantly more problems than the general population sample on all measures except for Anxiety and Peer Relationships. Having a COVID-19 affected friend/relative and a COVID-19 related change in parental work situation negatively moderated outcome, but not in the samples with pre-existing problems. All parents reported significant decreases in atmosphere at home, as did children from the general population.Conclusion: We observed significant differences in mental and social health between three child and adolescent samples during the COVID-19 pandemic lockdown and identified COVID-19-related factors influencing mental and social health.

Introduction: This paper describes the different ways in which information is being fed back to health care providers (HCPs) using the Dutch evidence-based KLIK Patient-Reported Outcome Measures (PROMs) portal (www.hetklikt.nu). KLIK was initially developed for children with a chronic illness and their parents, and recently expanded for use in adult health care. Patients complete online PROMs at home about their health-related quality of life (HRQOL), symptoms and/or psychosocial functioning before an outpatient consultation with their HCP. PROMs are subsequently converted into an individual KLIK electronic (e)PROfile and discussed during the consultation to facilitate systematic attention for HRQOL. Methods for PRO Score Interpretation: KLIK includes a variety of different PROMs. The KLIK ePROfile initially consisted of literal representations of the individual PROM items in the European traffic light colors (red, orange, green) and only one graph. Over the years, the KLIK ePROfile evolved into a broader spectrum of feedback options; (1) literal representation of individual items, (2) summary scores, and (3) graphic representations (4 options). Developing Recommendations for Acting on PRO Results: The primary goal of KLIK is to longitudinally monitor patient and parent self-reported or proxy-reported health outcomes, which means that the focus of KLIK is not mainly on recommending actions for PRO results. However, there are several aids that help interpretation of the KLIK ePROfile and recommendations are given for actions based on PROM scores. The main aid is the KLIK training, which includes a theoretical and a practical part. In the training, 2 tools—a decision tree and a summary of information about the KLIK ePROfile—are given to the HCPs to assist them in using KLIK. Discussion: Customization of a PROM portal is needed for each different patient group and clinical setting. Because the KLIK website is flexible, every PROM (with good psychometric qualities and permission of the publisher) can be built in. However, implementing and feeding back PROMs in pediatric health care encompasses different challenges, because different versions of the same PROM are needed for children of different ages, as well as proxy and self-report versions.
