Longitudinal Associations Between Use of Mobile Devices for Calming and Emotional Reactivity and Executive Functioning in Children Aged 3 to 5 Years

Prospective associations of screen time at age 2 with specific behavioral subscales at age 3: a cohort study

BACKGROUND

We aim to discover which, if any, of the subscales of internalizing and externalizing behavioral problems at age 3 are still associated with screen time (ST) at age 2 after adjusting for behavioral problems scores at age 2.

METHODS

This study was conducted under the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Information was gathered prospectively, with 7207 mother-child pairs included in the analysis. Children's ST was categorized in hours a day at age 2 (<1, 1-<2, 2-<4, ≥4). We assessed children's behavioral problems using the Child Behavior Checklist for Ages 1½-5 (CBCL) at ages 2 and 3. 'Having behavioral problems' was defined by them being within a clinical range for internalizing behaviors (withdrawn, somatic complaints, anxious/depressed and emotionally reactive) and externalizing behaviors (attention problems and aggressive behaviors) at age 3. Continuous scores on each of the behavioral problem scales at age 2 were used as covariates.

RESULTS

Greater ST for children at age 2 was associated with specific subscales for emotionally reactive and aggressive behaviors at age 3.

CONCLUSIONS

This study found that ST is prospectively associated with some behavioral scales but not others.

The Effect of Screen Habits and Alternative Activities on Tactile Exploration Skills in 6- to 36-Month-Old Toddlers

BACKGROUND/OBJECTIVES

With the rising ubiquity of digital media and screens in everyday life, toddlers are increasingly exposed to different screens from an early age (i.e., television, computer, tablet, phone). However, few studies have examined the effect of these screens on toddlers' perceptual development. Since tactile exploration skills are necessary for environmental discovery and overall development, the current research investigates the links between screen-use habits and the tactile exploration skills (with visual control) of 6- to 36-month-old toddlers.

METHODS

The study involved observing the interactions of 135 toddlers with various objects and assessing the complexity of their visuo-tactile exploration strategies through two original experimental tasks. Data concerning screen habits and other relevant factors, such as socio-economic level, were collected using a parental questionnaire.

RESULTS

Toddlers with greater screen exposure time demonstrated weaker tactile exploration skills and employed less age-appropriate exploration strategies. Socio-economic factors and parental engagement in alternative activities significantly influenced these developmental outcomes.

CONCLUSIONS

These findings emphasize the importance of reducing screen time and promoting interactive co-viewing and alternative activities to mitigate the negative effects of screen exposure. Further longitudinal research is needed to determine the long-term impacts of early screen exposure on tactile exploration and overall psychological development.

Early Childhood Screen Use Contexts and Cognitive and Psychosocial Outcomes: A Systematic Review and Meta-analysis

Importance

The multifaceted nature of screen use has been largely overlooked in favor of a simplistic unidimensional measure of overall screen time when evaluating the benefits and risks of screen use to early childhood development.

Objective

To conduct a systematic review and meta-analysis to examine associations of screen use contexts in early childhood with cognitive and psychosocial outcomes.

Data Sources

PsycINFO, Embase, MEDLINE Ovid, ProQuest, CINAHL, Web of Science, and Scopus were searched from inception to December 31, 2023.

Study Selection

A total of 7441 studies were initially identified. Studies were included if they examined associations between a contextual factor of screen use among children aged 0 to 5.99 years and cognitive or psychosocial development. Observational, experimental, and randomized clinical trial study designs were included.

Data Extraction and Synthesis

All studies were independently screened in duplicate following PRISMA guidelines. Effect sizes of associations (r) from observational studies were pooled using random-effects 3-level meta-analyses. The remaining study designs were narratively synthesized.

Main Outcomes and Measures

Screen use contexts included content (child directed and age inappropriate), type (program viewing and game or app use), co-use (or solo use), background television, caregiver screen use during child routines, and purpose. Outcomes were cognitive (executive functioning, language, and academic skills) or psychosocial (internalizing and externalizing behavior problems and socioemotional competence).

Results

Overall, 100 studies (176 742 participants) were included, and of these, 64 observational studies (pooled sample sizes ranging from 711 to 69 232) were included in meta-analyses. Program viewing (n = 14; k = 48; r, -0.16; 95% CI, -0.24 to -0.08) and background television (n = 8; k = 18; r, -0.10; 95% CI, -0.18 to -0.02) were negatively associated with cognitive outcomes, while program viewing (n = 6; k = 31; r, -0.04; 95% CI, -0.07 to -0.01), age-inappropriate content (n = 9; k = 36; r, -0.11; 95% CI, -0.17 to -0.04), and caregiver screen use during routines (n = 6; k = 14; r, -0.11; 95% CI, -0.20 to -0.03) were negatively associated with psychosocial outcomes. Co-use was positively associated with cognitive outcomes (n = 8; k = 28; r, 0.14; 95% CI, 0.03 to 0.25).

Conclusions and Relevance

Findings show small to moderate effect sizes that highlight the need to consider screen use contexts when making recommendations for families, clinicians, and educators beyond screen time limits; including encouraging intentional and productive screen use, age-appropriate content, and co-use with caregivers.

Young children's screen habits and first-time parents' reflections on screen use in socioeconomically disadvantaged Swedish settings: a mixed methods study

BACKGROUND

Despite WHO's recommendation of limited screen time for children < 2 years, they are worldwide established screen users. Several negative consequences are connected to excessive screen use among children. As parents are key actors in introducing screens to children, it is important to explore children's screen habits and parents' perspectives on screen in different populations, which could support the development of guidelines for healthier screen use. This study aimed to explore young children's screen use habits and describe first-time parents' reflections on children's screen use in socioeconomically disadvantaged Swedish settings.

METHODS

This mixed methods study was a part of larger studies within Stockholm County. The data were collected through semi-structured questionnaire-based interviews, among first-time parents (N = 386) of 15-18 months-olds at local Child Health Care centres during 2019-2022. Quantitative and qualitative data analyses conducted in parallel resulted in descriptive statistics and qualitative categories.

RESULTS

Most children (92.4%) used screens by the age of 15-18 months, commonly for a maximum of 30 min (48.5%) per day. Participants stated the most suitable age for starting screen use to be after (41.7%) or at (37.9%) the age of two years. Parents' reflections on screen use formed three main categories, each having two sub-categories: screen use patterns (screen-related time and reasons for screen use), perceived concerns with screen use (child development and social issues), and attitudes related to screen use (parents' attitudes towards screens and child's response to screens).

CONCLUSIONS

First-time parents in socioeconomically disadvantaged settings expressed awareness of possible negative screen-related effects and recommendations but did not always focus on long-term consequences when using screens in everyday life. Screens used as a short distraction, time spent together with screens, infants' contact with relatives overseas, and pedagogical children's programs and apps can be regarded as screen-related benefits. Encouraging parents' self-reflection on their screen use may be a way of contributing to healthier screen habits among young children. Future studies are suggested regarding parents' and children's excessive interest in screens and how to manage screen use as a family.

The importance of mother-child interaction on smart device usage and behavior outcomes among toddlers: a longitudinal study

BACKGROUND

In recent years, smart devices have become an integral part of daily life. However, longitudinal studies, particularly those regarding the relationship between toddlers' smart device usage and behavioral outcomes, are limited. Understanding the impact of parent-child interactions on this relationship is crucial for enhancing toddlers' developmental outcomes. Accordingly, this study examined the influence of early screen time and media content exposure on toddlers' behaviors, as well as the positive effects of mother-child interactions on this influence.

METHODS

We used relevant data related to 277 children born between November 2016 and July 2020 and who were part of an ongoing prospective follow-up study conducted across five hospitals in Taipei City, Taiwan. We analyzed (1) data from maternal reports regarding children's behavior by using the Child Behavior Checklist (for ages 11/2-5 years), (2) assessments of mother-child interactions by using the Brigance Parent-Child Interactions Scale, and (3) self-reported parental data covering the first 3 postpartum years. Statistical analyses involved group-based trajectory modeling and multiple linear regression.

RESULTS

A considerable increase in screen time between the ages of 1 and 3 years was associated with less favorable behavioral outcomes at age 3. These outcomes included somatic complaints [adjusted beta coefficient (aβ) = 2.17, 95% confidence interval (CI) = 0.39-3.95, p-value = 0.01], withdrawal (aβ = 2.42, 95% CI = 0.15-4.69, p-value = 0.04), and aggressive behavior (aβ = 6.53, 95% CI = 0.25-12.81, p-value = 0.04). This association was particularly evident among children with lower levels of mother-child interaction. Nevertheless, positive mother-child interactions mitigated most of the adverse effects. Additionally, increased exposure to games and cartoons was associated with poorer behavioral outcomes in all children except for those experiencing positive mother-child interactions.

CONCLUSION

Early mother-child interactions play a crucial role in mitigating the risk of behavioral problems in toddlers who spend prolonged periods looking at screens and who are frequently exposed to game and cartoon content.

Managing Screen Use in the Under-Fives: Recommendations for Parenting Intervention Development

The impact of excessive screen use on children's health and development is a public health concern and many countries have published recommendations to limit and guide the use of screen media in childhood. Despite this, international studies report that the majority of parents and children do not adhere to screen use recommendations. Existing research aiming to understand children' screen use has largely focused on older children, and on demographic and structural aspects of the child's environment. Parents play a central role in determining young children's screen use and identify numerous barriers to developing healthy screen use practices with their children. However, no clear models exist that incorporate key parenting factors in understanding children's screen use, which presents an impediment to intervention development. Likewise, while some evidence exists for interventions to improve children's screen use behaviours, most are focused on older children and parental involvement has generally been limited. In this paper, we overview key factors associated with screen use in young children (< 5 years) and summarise the existing evidence base for interventions designed to support healthy screen use. This paper proposes a conceptual model linking aspects of parenting and the socio-ecological environment to young children's screen use. Our proposed model could be used to design longitudinal studies of screen use predictors and outcomes, and inform intervention development. Finally, the paper provides key recommendations for future research, intervention development and testing.

Digital Devices Use and Fine Motor Skills in Children between 3-6 Years

(1) Background: The principal aim of our research was to explore the relationship between digital devices use and fine motor skills in children aged three to six years and to explore the effect of some socio-demographic factors. (2) Methods: we enrolled 185 children aged between three to six years. The parents of all the participants fulfilled a questionnaire to explore the digital device use, and their children performed a standardized test to assess fine motor skills (APCM-2). We performed the Spearman correlation test to explore the relationship between different variables. (3) Results: the children spent an average of 3.08 ± 2.30 h/day on digital devices. We did not find a significant association between the time of use of digital devices and fine motor skills (p = 0.640; r = -0.036). The youngest children experienced digital tools earlier than older ones (p < 0.001; r = 0.424) and they were also the ones who used digital tools more time afterwards (p = 0.012; -0.202). The children who had working parents spent more time on digital devices (p = 0.028; r = 0.164/p = 0.037; r = 0.154) and used digital devices earlier (p = 0.023; r = 0.171). (4) Conclusions: This data suggest that it would be useful to monitor the use of digital tools, especially in the very first years of life. Future studies are needed to further explore this topic.
