Background: Excessive crying, sleeping, and feeding problems in early childhood are major stressors that can result in parents feeling socially isolated and having low self-efficacy. Affected children are a risk group for being maltreated and developing emotional and behavioral problems. Thus, the development of an innovative and interactive psychoeducational app for parents of children with crying, sleeping, and feeding problems may provide low-threshold access to scientifically based information and reduce negative outcomes in parents and children. Objective: We aimed to investigate whether following the use of a newly developed psychoeducational app, the parents of children with crying, sleeping, or feeding problems experienced less parenting stress; gained more knowledge about crying, sleeping, and feeding problems; and perceived themselves as more self-effective and as better socially supported and whether their children’s symptoms decreased more than those of the parents who did not use the app. Methods: Our clinical sample consisted of 136 parents of children (aged 0-24 months) who contacted a cry baby outpatient clinic in Bavaria (Southern Germany) for an initial consultation. Using a randomized controlled design, families were randomly allocated to either an intervention group (IG; 73/136, 53.7%) or a waitlist control group (WCG; 63/136, 46.3%) during the usual waiting time until consultation. The IG was given a psychoeducational app that included evidence-based information via text and videos, a child behavior diary function, a parent chat forum and experience report, tips on relaxation, an emergency plan, and a regional directory of specialized counseling centers. Outcome variables were assessed using validated questionnaires at baseline test and posttest. Both groups were compared at posttest regarding changes in parenting stress (primary outcome) and secondary outcomes, namely knowledge about crying, sleeping, and feeding problems; perceived self-efficacy; perceived social support; and child symptoms. Results: The mean individual study duration was 23.41 (SD 10.42) days. The IG reported significantly lower levels of parenting stress (mean 83.18, SD 19.94) after app use compared with the WCG (mean 87.46, SD 16.67; P=.03; Cohen d=0.23). Furthermore, parents in the IG reported a higher level of knowledge about crying, sleeping, and feeding (mean 62.91, SD 4.30) than those in the WCG (mean 61.15, SD 4.46; P<.001; Cohen d=0.38). No differences at posttest were found between groups in terms of parental efficacy (P=.34; Cohen d=0.05), perceived social support (P=.66; Cohen d=0.04), and child symptoms (P=.35; Cohen d=0.10). Conclusions: This study provides initial evidence of the efficacy of a psychoeducational app for parents with child crying, sleeping, and feeding problems. By reducing parental stress and increasing knowledge of children’s symptoms, the app has the potential to serve as an effective secondary preventive measure. Additional large-scale studies are needed to investigate long-term benefits. Trial Registration: German Clinical Trials Register DRKS00019001; https://drks.de/search/en/trial/DRKS00019001

Background: Families with young children are particularly vulnerable for the stressors induced by the COVID-19 pandemic. However, studies on their psychosocial situation during the course of the crisis are still sparse. Methods: In a comparison of three survey waves (wave I and III = high COVID-19 incidences), we cross-sectionally investigated the proportion of families (N_total = 2940) with children aged 0–3 years experiencing pandemic burden, parenting stress, and parental and child mental health problems in relation to COVID-19 incidences and restrictions in Southern Germany via validated questionnaires. Potential influencing factors were also explored. Results: The number of parents with a high pandemic burden decreased over the course of the pandemic with a peak of 65.3% in wave I (significant changes except wave II versus III). Participants with high parenting stress significantly increased from 38.2% in wave I to 51.2% in wave III. The number of parents with symptoms of depression and anxiety remained constantly high with a maximum of 28.4% being affected. Infants with crying/sleeping problems increased significantly from 26.4% in wave I to 35.5% in wave III. Toddlers’ emotional and behavioral problems showed a peak of 23.9% in wave III (no significant changes). Increased family conflicts were the strongest predictor for parenting stress (ß = 0.355), maternal (ß = 0.305), infants’ (ß = 0.149) and toddlers’ (ß = 0.216) mental health problems during the pandemic. Conclusions: Psychosocial stress factors in families with infants and toddlers remained highly pronounced and even partly increased irrespective of pandemic events. The findings suggest a staggered negative impact of pandemic-related factors on young children’s mental health. Promoting infants’ mental health as well as strengthening parental resources by reducing parenting stress should be a top healthcare priority in the aftermath of COVID-19.

There is a lack of evidence-based app guidance for parents of children with crying, sleeping, and feeding problems who are often highly burdened and not likely to seek professional help. A new psychoeducational app for parents providing scientifically sound information via text and videos, a diary function, selfcare strategies, a chat forum and a regional directory of specialized counseling centers may serve as a low-threshold intervention for this target group. We investigated how parents perceived the app in terms of the following: (1) overall impression and usability, (2) feedback on specific app functions regarding usefulness and (3) possible future improvements. Our clinical sample of N = 137 parents of children aged from 0 to 24 months was recruited from a cry baby outpatient clinic in Southern Germany between 2019 and 2022. A convergent parallel mixed methods design was used to collect and analyse cross-sectional data on app evaluation. After app use within the framework of a clinical trial, parents filled in an app evaluation questionnaire. Most participants used the app at least once a week (86, 62.8 %) over an average period of 19.06 days (SD = 15.00). Participants rated overall impression and usability as good, and the informational texts, expert videos and regional register of counseling centers as appealing and useful. The diary function and chat forum were found to be helpful in theory, but improvements in implementation were requested, such as a timer function for the diary entry. Regarding future functionality, parents posed several suggestions such as the option to contact counseling centers directly via app, and the inclusion of the profile of their partners. Positive ratings of overall impression, usability, and specific app functions are important prerequisites for the app to be effective. App-based guidance for this target group should include easy-to-use information. The app is intended to serve as a secondary preventive low-threshold offer and to complement professional counseling.

Background/Objectives: Infant regulatory problems (RPs), i.e., crying, sleeping, and feeding problems, are associated with unfavorable outcomes in later childhood. RPs increased during the pandemic; however, their occurrence in the face of today’s societal challenges remains unclear. RPs are strongly linked to parenting stress and less positive parenting behaviors, but their interplay is less investigated. Methods: In this cross-sectional, questionnaire-based study (ntotal = 7039), we compared the incidences of crying, sleeping, and feeding problems in infants (0–2 years) in pandemic (npandemic = 1391) versus post-pandemic (npost-pandemic = 5648) samples in Germany. We also investigated the relationship between post-pandemic infant RPs and parenting behaviors with parenting stress as a potential mediator for fathers and mothers. Results: Crying/whining/sleeping problems (34.8%) and excessive crying (6.3%) were significantly more prevalent in the post-pandemic sample. In both mothers and fathers, infant RPs were significantly associated with less positive parenting behaviors. Parenting stress partially mediated this relationship. Conclusions: RPs in the post-pandemic era are even more prevalent than during the pandemic, highlighting the imperative for health care professionals to focus on infant mental health. Parenting stress emerges as an entry point for addressing the cycle of infant RPs and maladaptive behaviors in both fathers and mothers.

Background: Perinatal depression affects 10–15% of mothers and approximately 5% of fathers. However, only a small number of affected individuals seek treatment. If left unrecognized and untreated, it can have negative long-term consequences for the family’s health, leading to subsequent high costs. Early treatment is crucial, yet there is a notable underdiagnosis and undertreatment. Affected individuals are often seen during this time, e.g. in paediatric practices, but not by specialists in mental health. Consequently, this study aims to increase detection and treatment rates of affected individuals by implementing a screening for depression and psychosocial stress in perinatal and postpartum parents within routine obstetric and paediatric care with subsequent advice and—if necessary—further referral to a mental health specialist. Methods: UPlusE is a prospective, cluster-randomized controlled trial conducted in an outpatient setting. Obstetric and paediatric practices will be randomized into an intervention and control group (1:1 ratio). Practices and enrolling patients will be required to use specific smartphone apps (practice apps) for interaction. The screening will occur with the apps at each paediatric checkup up to the child’s age of 12 months, using the Edinburgh Postnatal Depression Scale (EPDS), KID-PROTEKT questionnaire, and the scale 1 (impaired bonding) of the Postpartum Bonding Questionnaire (PBQ-1). The goal is to screen 10,000 patients across Germany. Gynaecologists and paediatricians will receive certified training on peripartum depression. Participants in the intervention group with scores above cut-offs (EPDS ≥ 10, KID-PROTEKT ≥ 1, PBQ-1 ≥ 12) will receive counselling through their treating gynaecologists/paediatricians and will be provided with regional addresses for psychiatrists, psychotherapists, and “Frühe Hilfen” (early prevention) as well as family counselling centres, depending on symptom severity. At each screening, participants will be asked whether they sought support, where, and with whom (utilization). Utilization is the primary outcome. Discussion: The screening is designed to reduce underdiagnosis to enable suitable support at an early stage (especially for those often overlooked, such as individuals with “high-functioning depression”) and hence to avoid manifestation of mental health problems in the whole family, especially infants who are exceptionally dependent on their parents and their well-being will benefit from this program.

Familial hypercholesterolemia (FH) is the most frequent monogenic disorder (prevalence 1:250) in the general population. Early diagnosis during childhood enables pre-emptive treatment, thus reducing the risk of severe atherosclerotic manifestations later in life. Nonetheless, FH screening programs are scarce. VRONI offers all children aged 5–14 years in Bavaria a FH screening in the context of regular pediatric visits. LDL-cholesterol (LDL-C) is measured centrally, followed by genetic analysis for FH if exceeding the age-specific 95th percentile (130 mg/dl, 3.34 mmol/l). Children with FH pathogenic variants are treated by specialized pediatricians and offered a FH-focused training course by a qualified training center. Reverse cascade screening is recommended for all first-degree relatives. VRONI aims to prove the feasibility of a population-based FH screening in children and to lay the foundation for a nationwide screening program.
