RESUMEN
BACKGROUND: The COVID-19 pandemic negatively affected physical and psychological health worldwide. Pregnant women were likely more vulnerable to mental health difficulties due to the significant social, psychological, and hormonal changes they experience. During the pandemic, higher rates of antenatal depression and anxiety were observed compared to pre-pandemic rates. Increased mental health symptoms in pregnancy have been associated with adverse outcomes for child development. Understanding pandemic-specific preventive behaviours (i.e., mask use, physical distancing) and concerns may also be linked to maternal psychological well-being. PURPOSE: To compare matched pregnant and non-pregnant women (N = 474) to assess COVID-19 psychosocial impacts, preventive behaviours, and concerns. METHODS: This study used a matched analysis of data collected by the International COVID-19 Awareness and Responses Evaluation (iCARE) Study. Participants were matched on several demographic factors and analyses were adjusted for chronic illness and psychiatric disorder. RESULTS: Linear regression analyses indicated that pregnant women did not significantly differ from matched non-pregnant women for psychosocial impacts (B = 0.11, SE = 0.08, p = 0.178). Those who reported a chronic illness (B=-0.19, SE = 0.09, p = 0.036) or a psychiatric disorder (B=-0.28, SE = 0.09, p = 0.003) were more likely to report more significant psychosocial impacts. Logistic regression analyses indicated that pregnant women were more likely to report staying at home rather than going to work (OR = 2.01, 95% CI 1.31-3.08, p = 0.002) and being concerned about being infected (OR = 1.61, 95% CI 1.05-2.46, p = 0.028). CONCLUSIONS: Our findings in the context of the COVID-19 pandemic highlight the need to consider interventions targeting women, with chronic illnesses or psychiatric disorders, as they are often the most vulnerable.
RESUMEN
Negative emotionality (NE) was evaluated as a candidate mechanism linking prenatal maternal affective symptoms and offspring internalizing problems during the preschool/early school age period. The participants were 335 mother-infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment project. A Confirmatory Bifactor Analysis (CFA) based on self-report measures of prenatal depression and pregnancy-specific anxiety generated a general factor representing overlapping symptoms of prenatal maternal psychopathology and four distinct symptom factors representing pregnancy-specific anxiety, negative affect, anhedonia and somatization. NE was rated by the mother at 18 and 36 months. CFA based on measures of father, mother, child-rated measures and a semistructured interview generated a general internalizing factor representing overlapping symptoms of child internalizing psychopathology accounting for the unique contribution of each informant. Path analyses revealed significant relationships among the general maternal affective psychopathology, the pregnancy- specific anxiety, and the child internalizing factors. Child NE mediated only the relationship between pregnancy-specific anxiety and the child internalizing factors. We highlighted the conditions in which prenatal maternal affective symptoms predicts child internalizing problems emerging early in development, including consideration of different mechanistic pathways for different maternal prenatal symptom presentations and child temperament.

BACKGROUND: Good quality friendships and relationships are critical to the development of social competence and are associated with quality of life and mental health in childhood and adolescence. Through social distancing and isolation restrictions, the COVID-19 pandemic has had an impact on the way in which youth socialize and communicate with friends, peers, teachers and family on a daily basis. In order to understand children's social functioning during the pandemic, it is essential to gather information on their experiences and perceptions concerning the social changes unique to this period. The objective of this study was to document children and adolescents' perspectives regarding their social life and friendships during the COVID-19 pandemic, through qualitative interviews. METHODS: Participants (N = 67, 5-14 years) were recruited in May and June 2020. Semi-structured interviews were conducted via a videoconferencing platform. A thematic qualitative analysis was conducted based on the transcribed and coded interviews (NVivo). RESULTS: The upheavals related to the pandemic provoked reflection among the participants according to three main themes, each of which included sub-themes: (1) the irreplaceable nature of friendship, (2) the unsuspected benefits of school for socialization and (3) the limits and possibilities of virtual socialization. CONCLUSIONS: The collection of rich, qualitative information on the perspectives of children and adolescents provides a deeper understanding of the consequences of the pandemic on their socialization and psychological health and contributes to our fundamental understanding of social competence in childhood.

The prevalence of mental health problems represents a significant burden on school and community health resources as early as preschool. Reducing this burden requires a better understanding of the developmental mechanisms linking children's early vulnerabilities with mental health after the transition to formal schooling. The 3D-Transition Study (2017-2021) follows 939 participants from a pregnancy cohort in the province of Québec, Canada, as they transition to kindergarten and first grade to examine these mechanisms. Biannual assessments include completed questionnaires from 2 parents as well as teachers, parent-child observations, anthropometric measurements, and age-sensitive cognitive assessments. Saliva is also collected on 11 days over a 16-month period in a subsample of 384 participants to examine possible changes in child salivary cortisol levels across the school transition and their role in difficulties observed during the transition. A combination of planned missing-data designs is being implemented to reduce participant burden, where incomplete data are collected without introducing bias after the use of multiple imputation. The 3D-Transition Study will contribute to an evidence-based developmental framework of child mental health from pregnancy to school age. In turn, this framework can help inform prevention programs delivered in health-care settings during pregnancy and in child-care centers, preschools, and schools.

This study used a person-centered approach to identify subgroups of adolescents who are at risk for depression and suicidal ideation. Latent class analysis was first applied to 1,290 adolescents from a Canadian cohort study in order to identify latent vulnerability subtypes based on 18 psychosocial vulnerability factors. Logistic regression analyses were conducted to study the associations between class membership and depressive symptoms and suicidal ideation 2 years later. The moderating role of sex in the associations between latent classes and depressive symptoms was explored. Five latent classes were identified: Low Vulnerability (42%), Substance Use Only (13%), Moderate Vulnerability (28%), Conduct Problems (8%) and High Vulnerability (9%). Compared with the Low Vulnerability class, the probabilities of presenting depressive symptoms were higher for the Substance Use Only class, OR = 1.93, 95% CI [1.21, 3.06], the Moderate Vulnerability class, OR = 2.96, 95% CI [2.09, 4.20], the Conduct Problems class, OR = 3.03, 95% CI [1.84, 4.98], and the High Vulnerability class, OR = 5.4, 95% CI [3.42, 8.53]. Furthermore, interaction effects with sex were identified in relation to depressive symptoms only. The probability of presenting suicidal ideation was higher only for the High Vulnerability class, OR = 4.51, 95% CI [2.41, 8.43]. This study highlights the importance of a person-centered perspective that considers both vulnerability subtypes and sex because these associations are complex rather than linear or additive.

Among children exposed to elevated maternal depression symptoms (MDS), recent studies have demonstrated reduced internalizing and externalizing problems for those who have attended formal childcare (i.e., center-based, family-based childcare). However, these studies did not consider whether childcare attendance is associated with benefits for the child only or also with reduced MDS. Using a four-wave longitudinal cross-lagged model, we evaluated whether formal childcare attendance was associated with MDS or child behavior problems and whether it moderated longitudinal associations between MDS and child behavior problems and between child behavior problems and MDS. The sample was drawn from a population-based cohort study and consisted of 908 biologically related mother-child dyads, followed from 5 months to 5 years. Attending formal childcare was not associated with MDS or child behavior problems but moderated the association between MDS at 3.5 years and child internalizing and externalizing problems at 5 years as well as between girls' externalizing problems at 3.5 years and MDS at 5 years. No other moderation of formal childcare was found. Findings suggest that attending formal childcare reduces the risks of behavior problems in the context of MDS but also the risk of MDS in the context of girls' externalizing problems.

Recent studies have shown that the association between maternal depression and child outcome can be moderated by children's experience of childcare (e.g., daycare) during early childhood (0-5 years). We also know that maternal depression in the child's early years has long-term associations with child development. However, the moderating role of childcare quality on long-term associations between maternal depression and child outcome has not been thoroughly investigated. This article examined longitudinal associations between probable maternal depression (PMD) during early childhood (0-5 years) and childcare quality on children's emotional and behavioral development at the age of 7-8 years (N = 207). Childcare quality was evaluated through observations within the settings. PMD during early childhood was assessed using complementary information from interviews conducted with the mother and current maternal symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Internalizing and externalizing behaviors were reported by the mother, father and the child at age 7-8 years. Results indicate that when mothers reported clinically relevant depression in early childhood, 7-8-year-old children demonstrate fewer behavioral problems if they attended a higher quality childcare setting. The moderating role of childcare quality remained after considering current maternal depression symptoms. Therefore, it is important to ensure high-quality childcare during early childhood to optimize child development.

OBJECTIVE: To test the associations between the timing and chronicity of maternal depression symptoms (MDS) and children's long-term verbal abilities. STUDY DESIGN: Participants were 1073 mother-child pairs from a population-based birth cohort in Canada. MDS were assessed at ages 5 months, 1.5, 3.5, and 5 years using the Center for Epidemiologic Studies Depression Scale. Verbal abilities were measured at 5, 6, and 10 years using the Peabody Picture Vocabulary Test-Revised (PPVT-R). Multiple linear regression models were used to estimate the association between timing (early: 5 months and/or 1.5 years vs late 3.5 and/or 5 years) and chronicity (5 months, 1.5, 3.5, and 5 years) of exposure to elevated MDS and children's mean PPVT-R scores. RESULTS: Children exposed to chronic MDS had lower PPVT-R scores than children never exposed (mean difference = 9.04 [95% CI = 2.28-15.80]), exposed early (10.08 [3.33-16.86]) and exposed late (8.69 [1.85-15.53]). There were no significant differences between scores of children in the early compared with the late exposure group. We adjusted for mother-child interactions, family functioning, socioeconomic status, PPVT-R administration language, child's birth order, and maternal IQ, psychopathology, education, native language, age at birth of child, and parenting practices. Maternal IQ, (η2 = 0.028), native language (η2 = 0.009), and MDS (η2 = 0.007) were the main predictors of children's verbal abilities. CONCLUSIONS: Exposure to chronic MDS in early childhood is associated with lower levels of verbal abilities in middle childhood. Further research is needed in larger community samples to test the association between MDS and children's long-term language skills.

Background: Maternal vitamin D insufficiency (plasma 25-hydroxyvitamin D [25(OH)D] <75 nmol/L) may play a role in ethnic disparities in rates of preterm and spontaneous preterm births.Objective: We explored the relation between maternal plasma 25(OH)D concentration in the first trimester (8-14 wk of gestation) and the risk of preterm and spontaneous preterm births (<37 wk of gestation) by ethnicity.Methods: We designed a case-control study that included 120 cases of preterm birth (<37 wk of gestation) and 360 term controls (≥37 wk of gestation) of singleton pregnancies from the 3D cohort, a multicenter study in 2456 pregnant women in Quebec, Canada. Plasma 25(OH)D was measured by LC-mass spectrometry. We compared the distribution of vitamin D status between cases and controls for 8 ethnic minority subgroups. We explored the association between maternal plasma 25(OH)D concentration and preterm and spontaneous preterm births with the use of splines in logistic regression by ethnicity.Results: The distributions of maternal vitamin D status (<50, 50-75, and >75 nmol/L) were different in preterm and spontaneous preterm birth cases compared with controls but only in women of ethnic minority (P-trend = 0.003 and 0.024, respectively). Among ethnic subgroups, sub-Saharan Africans (P-trend = 0.030) and Arab-West Asians (P-trend = 0.045) showed an inverse relation between maternal vitamin D status and the risk of preterm birth. Maternal plasma 25(OH)D concentrations of 30 nmol/L were associated with 4.05 times the risk of preterm birth in the total ethnic minority population (95% CI: 1.16, 14.12; P = 0.028) relative to participants with a concentration of 75 nmol/L. In contrast, there was no such association among nonethnic women (OR: 0.94; 95% CI: 0.48, 1.82; P = 0.85). There was no association when we considered only spontaneous preterm births in the total ethnic minority population (OR: 1.75; 95% CI: 0.39, 7.79; P = 0.46).Conclusion: Vitamin D insufficiency is associated with an increased risk of preterm birth in ethnic minority women in Canada.

BACKGROUND: Maternal depression is a risk factor for adverse outcomes in the child, including emotional and behavioural difficulties. There is evidence that child care attendance during the preschool years may moderate associations between familial risk factors and child outcome. However, the possibility that high-quality child care provides protection for children exposed to maternal depression or that low-quality child care provides additional risk has not been investigated. We study whether child-care quality moderates the association between probable history of maternal depression (PMD) and child behavioural and emotional outcomes over the preschool period. METHODS: Within a longitudinal study, we examined PMD (no depression; clinical PMD before the child's birth; subclinical PMD from 0 to 5 years; clinical PMD from 0 to 5 years), child-care quality and child emotional and behavioural difficulties at the ages of 2, 3 and 4 years. Child-care quality was evaluated in settings, and trajectories were calculated to reflect (a) global quality and (b) two quality subfactors: 'Teaching and interactions' and 'Provision for learning'. Data were analysed for 264 families. RESULTS: Significant interactions emerged between clinical PMD and global quality of child care for children's externalising behaviour (b = -.185, p = .008), more specifically hyperactivity/inattention (b = -.237, p = .002). In the context of clinical PMD, children attending high-quality child care presented fewer difficulties than those attending a low-quality care. Child-care quality was not associated with outcomes for children whose mothers did not report a PMD or a PMD before their birth. CONCLUSIONS: In the context of PMD, high-quality child care was associated with fewer behavioural problems and may thus constitute a protective factor.

A vast body of literature shows that maternal depression has long-term adverse consequences for children. However, only very few studies have documented the effect of maternal depression on children's ability to process emotional expressions and even fewer incorporated measures of observed maternal sensitivity to further tease apart whether it is the symptoms per se or the associated impact via maternal sensitivity that affects children's developing emotion-processing abilities. In a large community sample of Dutch preschoolers (N = 770), we examined independent and mediated effects of maternal depressive symptoms and sensitivity on children's ability to recognize emotional expressions using a nonverbal and a verbal task paradigm. Maternal depressive symptoms predicted less accurate emotion labeling in children, while maternal sensitivity was associated with more accurate emotion matching, especially for sadness and anger. Maternal sensitivity did not mediate the observed associations between mothers' depressive symptoms and children's emotion recognition, and effects were similar for boys and girls. Given that maternal depressive symptoms and sensitivity affected nonoverlapping areas of young children's emotion recognition, prevention and intervention efforts should focus on both alleviating maternal depressive symptoms and improving maternal sensitivity at the same time in order to maximize benefit.

The purpose of this study is to examine whether maternal depressive symptoms predict low positive emotionality and high temperamental fearfulness in preschool children. Maternal depressive symptoms were assessed prenatally and at 2, 6, and 36 months postnatally. Positive emotionality and temperamental fearfulness were assessed using laboratory observations in a large cohort of typically developing Dutch preschoolers (N = 799; 404 boys) at age 36 months (M = 37.53, SD = 1.50). Children exposed to elevated levels of maternal depressive symptoms in the first 3 years of life behaved less fearfully at age 3 years in a novel context that primarily elicited a startle response (B = -0.08, SE = 0.03, p = .01). The severity rather than timing of or change in maternal depressive symptoms accounted for the observed effect. In the present sample, maternal depressive symptoms were not associated with positive emotionality in the offspring (p > .05). Findings suggest a relation between maternal depressive symptoms and decreased offspring fearfulness in a low-risk community sample of young children.

Temperament and psychopathology are intimately related; however, research on the prospective associations between positive emotionality, defined as a child's positive mood states and high engagement with the environment, and psychopathology is inconclusive. We examined the longitudinal relation between positive emotionality and internalizing problems in young children from the general population. Furthermore, we explored whether executive functioning mediates any observed association. Within a population-based Dutch birth cohort, we observed positive emotionality in 802 children using the laboratory temperament assessment battery at age 3 years. Child behavior checklist (CBCL) internalizing problems (consisting of Emotionally Reactive, Anxious/Depressed, and Withdrawn scales) were assessed at age 6 years. Parents rated their children's executive functioning at ages 4 years. Children with a lower positive emotionality at age 3 had a higher risk of withdrawn problems at age 6 years (OR = 1.20 per SD decrease in positive emotionality score, 95 % CI: 1.01, 1.42). This effect was not explained by preexisting internalizing problems. This association was partly mediated by more problems in the shifting domain of executive functioning (p < 0.001). We did not find any relation between positive emotionality and the CBCL emotionally reactive or anxious/depressed scales. Although the effect sizes were moderate, our results suggest that low levels of positive emotionality at preschool age can result in children's inflexibility and rigidity later in life. The inflexibility and rigidity are likely to affect the child's drive to engage with the environment, and thereby lead to withdrawn problems. Further research is needed to replicate these findings.

A large body of evidence demonstrates that childhood interpersonal trauma is associated with poorer parental and couple outcomes following the birth of a new child. As a unique component of couple functioning, parenting alliance is key during this transition period and is associated with long-term parental and child well-being. However, parenting alliance remains understudied in relation to childhood trauma, and little is known regarding the underlying mechanisms of this relationship among couples. Given its documented role in the intimate relationships of childhood interpersonal trauma-exposed individuals, dispositional mindfulness could be considered as a potential explanatory mechanism. Using a dyadic approach, this study examined the role of dispositional mindfulness, and its different facets, in the association between cumulative childhood interpersonal trauma (CCIT) and parenting alliance. A randomly selected community sample of 421 parental couples with infants completed online questionnaires. For both mothers and fathers, CCIT was associated with a more negative perception of parenting alliance through lower dispositional mindfulness, specifically through lower scores on the nonjudgment and describing facets. Moreover, results revealed dyadic indirect effects between parents' CCIT and their partner's parenting alliance through both partners' dispositional mindfulness. This study provides insight on how parents of an infant may influence each other's perceived parenting alliance through their dispositional mindfulness. Results also highlight mindfulness as a relevant mechanism for CCIT survivors who struggle to establish or maintain a positive parenting alliance, as well as the need to involve both parents in research and intervention.

Interventions targeting children's eco-anxiety have focused on fostering hope, however this is disconnected from children's need to explore and express despair regarding the climate crisis. Adults can help by acknowledging and discussing these emotions with children.
RESUMEN
BACKGROUND: Evidence exists that maternal antenatal depression may have adverse impacts on perinatal outcomes. However, the results of those studies are inconsistent and mainly focus on maternal depressive symptoms in the second or third trimester. METHODS: This prospective cohort study used a sub-sample of participants from the Sino-Canadian Healthy Life Trajectories Initiative trial. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depressive symptoms in the first, second, and third trimesters, respectively. Infant growth indicator measurements were conducted in the first year of life. Logistic regression, Spearman correlation analyses and Generalized estimation equation (GEE) models were used to test the hypotheses. RESULTS: 2053 participants were recruited in this study, 326 of whom had at least one EPDS score ≥ 10 during pregnancy. A higher EPDS score in the first (aOR=1.053, 95â¯% CI: 1.004-1.103) or in the second trimester (aOR=1.060, 95â¯% CI: 1.007-1.115) was associated with greater risk of macrosomia. A higher EPDS score in the third trimester was associated with higher risks of preterm birth (aOR=1.079, 95â¯% CI: 1.006-1.157) and the infant being small for gestational age (aOR=1.097, 95â¯% CI: 1.015-1.185). GEE models showed that a greater EPDS score in the third trimester was associated with higher infant subscapular skinfold thickness (adjusted ß=0.026, 95â¯% CI: 0.003-0.050). CONCLUSION: Maternal depressive symptoms in different trimesters were differentially associated with infant weight and growth parameters at birth and postnatally. The present study further highlights the importance of depression screening in all trimesters of pregnancy, including the first trimester.
RESUMEN
BACKGROUND: Neuroimaging findings have provided evidence for a relation between variations in brain structures and attention deficit/hyperactivity disorder (ADHD). However, longitudinal neuroimaging studies are typically confined to children who have already been diagnosed with ADHD. In a population-based study, we aimed to characterize the prospective association between brain structures measured during infancy and executive function and attention deficit/hyperactivity problems assessed at preschool age. METHODS: In the Generation R Study, the corpus callosum length, the gangliothalamic ovoid diameter (encompassing the basal ganglia and thalamus), and the ventricular volume were measured in 784 6-week-old children using cranial postnatal ultrasounds. Parents rated executive functioning at 4 years using the behavior rating inventory of executive function-preschool version in five dimensions: inhibition, shifting, emotional control, working memory, and planning/organizing. Attention deficit/hyperactivity problems were assessed at ages 3 and 5 years using the child behavior checklist. RESULTS: A smaller corpus callosum length during infancy was associated with greater deficits in executive functioning at 4 years. This was accounted for by higher problem scores on inhibition and emotional control. The corpus callosum length during infancy did not predict attention deficit/hyperactivity problem at 3 and 5 years, when controlling for the confounders. We did not find any relation between gangliothalamic ovoid diameter and executive function or Attention deficit/hyperactivity problem. CONCLUSIONS: Variations in brain structures detectible in infants predicted subtle impairments in inhibition and emotional control. However, in this population-based study, we could not demonstrate that early structural brain variations precede symptoms of ADHD.

Breastfeeding during infancy is associated with a range of short- and long-term health benefits. We examine whether breastfeeding in the first 2 months of life is associated with structural markers of brain development in infants from the general population. This study was embedded within the Generation R study. Cranial ultrasounds were obtained at approximately 7 weeks post-natal age. The diameter of the gangliothalamic ovoid, corpus callosum length, ventricular volume and head circumference were measured. Maternal reports of breastfeeding were obtained at 2 months of age. We examined associations in relation to current breastfeeding practices (exclusively breastfed, n = 318, breast- and bottle-fed, n = 119, and bottle-fed, n = 243). Analyses were adjusted for head size and relevant covariates. Secondary analyses were conducted for breastfeeding history (exclusively breastfed, n = 318, breast- and bottle-fed, n = 281, and never breastfed, n = 81). Exclusive breastfeeding was associated with more optimal brain development compared with babies who were bottle-fed or never breastfed. Results were most consistent for gangliothalamic ovoid diameter. Larger gangliothalamic ovoid diameters were evident in babies who were exclusively breastfed compared with bottle-fed babies [difference between means (95% confidence interval) = 0.21(0.02, 0.39), P = 0.02]. Smaller ventricular volume and larger head circumference were also found for exclusively breastfed babies. Breastfeeding was not significantly associated with corpus callosum length. Maternal reports of breastfeeding are associated with more mature brain development within the first 2 months of life. Results are most consistent for gangliothalamic ovoid diameter, a subcortical structure rich in docosahexaenoic acid. Findings also pointed to non-specific neural developmental advantage for exclusively breastfed babies.

Postpartum depression is the most commonly reported mental health issue among parents welcoming a new child, with long-term impacts on the well-being of their family. Survivors of childhood interpersonal trauma (CIT) appear to be more vulnerable with higher rates of postpartum depressive symptoms. Yet, studies are needed on protective mechanism that can buffer the link between CIT and postpartum depressive symptoms, to identify factors that can promote resilience in CIT survivors as they navigate this demanding period. Studies also need to include both parents to adopt a comprehensive dyadic perspective. This study examined the moderating role of mindfulness, a protective mechanism documented as key for both postpartum mental health and trauma processing, in the association between CIT and postpartum depressive symptoms in parental couples. A randomly selected sample of 843 couples who recently welcomed a new child completed self-reported measures of CIT, dispositional mindfulness and postpartum depression. Path analyses showed that more experience of CIT was associated with higher levels of postpartum depression, but this association was weaker in parents with higher dispositional mindfulness. Exploration of mindfulness facets yielded that higher disposition to act with awareness and observation acted as specific buffers, for fathers and mothers respectively. In addition, more CIT reported by one parent was linked with their partner's higher depressive symptoms. These findings shed light on the protective role of mindfulness during the postpartum period to protect against postpartum depression in parents who are CIT survivors and their partners.

Studies examining the associations between adolescent social media use and depression/anxiety symptoms show inconsistent results and do not elucidate the direction of associations. Differences in how studies operationalize social media use and consider potential moderating effects of sex and extraversion could contribute to inconsistencies. A distinction has been made between three types of social media use: passive, active and problematic. This study examined longitudinal associations between these types of adolescents' social media use and depression/anxiety symptoms and moderation effects of sex or extraversion. At ages 13 (T1) and 14 (T2), 257 adolescents completed an online questionnaire regarding their depression and anxiety symptoms and problematic social media use as well as three social media use diaries. Cross-lagged panel modeling (CLPM) revealed a positive association between problematic use and later anxiety symptoms (ß = .16, p = .010). Extraversion moderated the association between active use and anxiety (ß = -.14, p = .032). Specifically, active use predicted higher subsequent anxiety symptoms only in adolescents with low to moderate levels of extraversion. No sex moderation was found. While social media use (active or problematic) predicted later anxiety symptoms (but not depression), the reverse was not the case. However, highly extraverted individuals seem to be less vulnerable to potential negative effects of social media use.
