<abstract>
<p>Playing computer and video games (so-called <italic>gaming</italic>) is of great popularity among children and adults. But for some people, gaming gets out of hand and can result in a <italic>Gaming Disorder</italic> (GD). Among others, high neuroticism and low conscientiousness are considered to play a role in the etiology of GD. Next to personality traits, environmental variables are debated such as the parental influence on children&#x00027;s gaming behavior. In detail, parental gaming behavior could have role model functions for children. Based on empirical observations and theoretical frameworks, it was hypothesized that higher tendencies to GD in children are associated with higher neuroticism, lower conscientiousness, and higher parental tendencies to GD. In an online survey <italic>N</italic> = 493 parents (<italic>n</italic> = 472 females; age: <italic>M</italic> = 36.30, <italic>SD</italic> = 5.46) rated their own and their children&#x00027;s (<italic>n</italic> = 233 girls, <italic>n</italic> = 260 boys; age: <italic>M</italic> = 6.03, SD = 2.30) tendencies to GD by the <italic>Gaming Disorder Test</italic> (GDT) and their children&#x00027;s personality by the <italic>Big Five Inventory</italic> (BFI). Neuroticism was significantly correlated with the GDT scores of boys (<italic>rho</italic> = 0.256, <italic>p</italic> = 0.001) and girls (<italic>rho</italic> = 0.300, <italic>p</italic> = 0.001), while a significant correlation with conscientiousness was only present for boys (<italic>rho</italic> = &#x02212;0.196, <italic>p</italic> = 0.010). Parents&#x00027; and children&#x00027;s general playing of computer and video games were interdependent [&#x003C7;<sup>2</sup>(1) = 29.14, <italic>p</italic> &#x0003C; 0.001]; hence, if parents reported to be gamers, their children were more likely gamers as well. The GDT scores of parents and children were positively correlated (boys: <italic>rho</italic> = 0.36; <italic>p</italic> = 0.002; girls: <italic>rho</italic> = 0.33, <italic>p</italic> = 0.004). The results indicate that already in children the personality traits neuroticism and conscientiousness are associated with tendencies toward GD. Moreover, as gaming of parents and children was related to each other, it is conceivable that parents influence their children&#x00027;s gaming behavior via their own gaming behavior. Therefore, parents should be aware of their exemplary function for children and may overthink their own gaming behavior. But it has to be mentioned that the correlational nature of the present work allows no insights regarding causal relations.</p></abstract>

<title>Introduction</title>
<p>Gaming is considered as playing online and/or offline computer and video games on a technical device such as computer, laptop, console, or smartphone (<xref ref-type="bibr" rid="B1">1</xref>), but excessive gaming can become a problematic behavior. Therefore, in May 2019, the World Health Organization (WHO) acknowledged Gaming Disorder (GD) as an official diagnosis in its recent 11th revision of the <italic>International Classification of Diseases</italic> (ICD-11) (<xref ref-type="bibr" rid="B2">2</xref>). The diagnosis criteria for online as well as offline GD are as follows: (i) impaired control over gaming, (ii) gaming becomes the main focus of life at cost of other everyday life activities, and (iii) gaming is continued, although the afflicted person already faces negative consequences in everyday functioning (family, school, work, etc.). It is important to note that a GD usually is diagnosed if the mentioned symptoms appear over a period of at least 12 months, with the exception of severe cases (<xref ref-type="bibr" rid="B2">2</xref>). According to our knowledge, no representative prevalence estimations of GD based on the ICD-11 diagnosis exist (<xref ref-type="bibr" rid="B3">3</xref>). However, a good indication represents the prevalence of Internet Gaming Disorder (IGD), a diagnosis of the <italic>Diagnostic and Statistical Manual of Mental Disorders&#x02013;5th edition</italic> (DSM-5) (<xref ref-type="bibr" rid="B4">4</xref>), which is considered to be up to 3.05% worldwide, with males 2.5 times more often afflicted than females (<xref ref-type="bibr" rid="B5">5</xref>).</p>
<p>A prominent model to explain the development of GD (and other Internet and media-related use disorders) represents the I-PACE model (<xref ref-type="bibr" rid="B6">6</xref>). The model presumes that an <italic>i</italic>nteraction of certain predisposing <italic>p</italic>erson, <italic>a</italic>ffect, <italic>c</italic>ognition, and <italic>e</italic>xecution variables is of high relevance to understand the etiogenesis of GD. In the context of the present study, the main focus is on one important person variable mentioned within the I-PACE model, namely <italic>personality</italic> (<xref ref-type="bibr" rid="B6">6</xref>). Personality describes stable emotional, motivational, and cognitive dispositions of a person resulting in stable behavioral tendencies (<xref ref-type="bibr" rid="B7">7</xref>). In the context of the I-PACE model, among others, high neuroticism and low conscientiousness have been mentioned as relevant personality traits going along with higher tendencies toward addictive behaviors such as GD (<xref ref-type="bibr" rid="B6">6</xref>). The theoretical assumptions of the I-PACE model are supported by findings of systematic reviews that reported Internet-related GD being positively related with neuroticism but negatively related with conscientiousness (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B9">9</xref>). A recent large-scale international study also provides support for these associations between personality and GD (<xref ref-type="bibr" rid="B10">10</xref>). However, the vast majority of research regarding Internet-related GD and personality was only conducted in adolescents and adults but not in children (<xref ref-type="bibr" rid="B8">8</xref>, <xref ref-type="bibr" rid="B9">9</xref>). Nevertheless, playing computer and video games represents a popular leisure activity that is already performed at an early age (<xref ref-type="bibr" rid="B11">11</xref>, <xref ref-type="bibr" rid="B12">12</xref>). However, several research works show that excessive gaming might have a negative impact on children&#x00027;s (psychosocial) development like on prosocial behavior, social competence, or academic engagement (<xref ref-type="bibr" rid="B12">12</xref>&#x02013;<xref ref-type="bibr" rid="B14">14</xref>). Therefore, it is of special interest to get insights into vulnerability factors for exuberant gaming or even a GD in children, and high neuroticism and low conscientiousness could be two such factors.</p>
<p>Especially in young children, not only their own personality but also their parents might influence their gaming behavior. Within a meta-analysis, it was shown that the parent&#x02013;child relationship as well as the parental influence on gaming are of relevance whether children and adolescents develop a problematic gaming behavior (<xref ref-type="bibr" rid="B15">15</xref>). While a close parent&#x02013;child relationship (<xref ref-type="bibr" rid="B16">16</xref>) and parental supervision of gaming (<xref ref-type="bibr" rid="B17">17</xref>) might have a protective influence, parental gaming is considered to be a risk factor (<xref ref-type="bibr" rid="B18">18</xref>, <xref ref-type="bibr" rid="B19">19</xref>). The latter might be explained by the <italic>Social Learning Theory</italic> (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B21">21</xref>) according to which children tend to imitate their role models&#x00027; behavior as this is especially appealing for them. That leads to the assumption that next to children&#x00027;s personality, parental gaming might be another vulnerability factor for children to develop a problematic gaming behavior or even a GD.</p>
<p>Therefore, the aim of the present work was to investigate two possible vulnerability factors for problematic gaming behavior in children: children&#x00027;s personality and parental gaming. It was expected that in children, the same associations between the personality traits neuroticism and conscientiousness and tendencies to GD can be observed as in adolescents and adults. Furthermore, it was expected that parental and children&#x00027;s gaming are positively associated with each other. To sum up, the following three hypotheses are investigated in the present study:</p>
<p>i) Higher neuroticism and lower conscientiousness are linked to higher GD tendencies in children.</p>
<p>ii) Parents reporting to play computer and video games are more likely to have children who play computer and video games as well.</p>
<p>iii) Tendencies to GD of parents and their children are positively correlated with each other.</p>
<p>It has to be mentioned that the present work is part of a larger project, and first results were already presented in Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>) to the point when data of 249 participants were available. In this subsample, the authors observed that parents who reported to play computer and video games were more likely to report that their children were gaming as well. Furthermore, the GD tendencies of parents and their children were positively associated with each other (<xref ref-type="bibr" rid="B22">22</xref>). Please note that this work is available in German language only.</p>

<title>Materials and Methods</title>
<sec>
<title>Procedure</title>
<p>Data were collected <italic>via</italic> a two-part parental online survey between February 2020 and June 2021. The study was advertised in schools, kindergartens, an online platform of pediatricians, and <italic>via</italic> different online media channels (Facebook, Instagram). In the first part of the survey, children&#x00027;s personality and gaming behavior were assessed; in the second part, parents&#x00027; gaming behavior was of interest. Participation was anonymous. All participants provided electronic consent before filling in the survey. The present study was approved by the local Ethics Committee of Ulm University, Ulm, Germany, in August 2018 (253/18).</p>
</sec>
<sec>
<title>Participants</title>
<p>In total, <italic>N</italic> = 493 German parents (19 males, 472 females, 2 neither defining as male nor female; age in years: <italic>M</italic> = 36.30, <italic>SD</italic> = 5.46) participated in the present study. Inclusion criteria were a child&#x00027;s minimum age of 3 years, available data for both parts of the survey, and no double participation. Double participation was checked with a yes/no item &#x0201C;Did you participate in this study before?&#x0201D;. If former participation was stated with &#x0201C;yes&#x0201D;, the date of former participation was asked. If a date different from the recruiting phase of the study (February 2020 to June 2021) was stated, participants were included in the data analyses. Every parent filled in the survey for only one child. Parents of several children could decide themselves for which child they fill in the survey. Therefore, data of <italic>N</italic> = 493 children were available (260 boys, 233 girls; age in years: <italic>M</italic> = 6.03, <italic>SD</italic> = 2.30).</p>
<p>As mentioned earlier, the data of <italic>n</italic> = 249 parents and their children were already included in the paper by Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>). In the meantime, a larger sample was collected. As research questions here overlap only partly with the former work, these <italic>n</italic> = 249 data sets are also included in the present work. Therefore, results are reported only for the total sample of <italic>N</italic> = 493.</p>
</sec>
<sec>
<title>Gaming Behavior</title>
<p>It was separately asked for children (external report) and parents (self-report) if online and/or offline video/computer games were played at least occasionally within the last 12 months (yes/no question). That was the case for <italic>n</italic> = 195 (39.6%) parents and for <italic>n</italic> = 247 (50.1%) children. The overlap of gaming parents and gaming children within the same family was <italic>n</italic> = 127. Tendencies toward GD were assessed by the <italic>Gaming Disorder Test</italic> (GDT) (<xref ref-type="bibr" rid="B1">1</xref>). Parents reported their own tendencies via self-report in the German version of the GDT as presented in Montag et al. (<xref ref-type="bibr" rid="B23">23</xref>). For gaming children (<italic>n</italic> = 247), an external report with a German modified version of the GDT suitable for parents was used (<xref ref-type="bibr" rid="B22">22</xref>). Both versions of the GDT consist of four items that are answered on a five-point Likert scale (1 = &#x0201C;never&#x0201D; to 5 = &#x0201C;very often&#x0201D;). Sum scores were calculated separately for the self-report (parents&#x00027; GDT; &#x003B1; = 0.78) and the external report (child&#x00027;s GDT; &#x003B1; = 0.80). A confirmatory factor analysis (CFA) with maximum likelihood (ML) estimators was performed to assess the model fit of both GDT versions. For the external GDT (child&#x00027;s gaming behavior), the model fit was not acceptable [&#x003C7;<sup>2</sup>(2) = 83.191, <italic>p</italic> &#x0003C; 0.001; CFI = 0.817; TLI = 0.451; RMSEA = 0.405; SRMR = 0.102], but the factor loadings of all items were acceptable (&#x003BB;<sub>1</sub> = 0.812, &#x003BB;<sub>2</sub> = 0.869, &#x003BB;<sub>3</sub> = 0.683, &#x003BB;<sub>4</sub> = 0.552) and in accordance with the reported loadings by Pontes et al. (<xref ref-type="bibr" rid="B1">1</xref>). The model fit for the self-report (parents&#x00027; GDT) was in the lower range of acceptability [&#x003C7;<sup>2</sup>(2) = 19.959, <italic>p</italic> &#x0003C; 0.001; CFI = 0.934; TLI = 0.802; RMSEA = 0.215; SRMR = 0.049], with factor loadings of &#x003BB;<sub>1</sub> = 0.687, &#x003BB;<sub>2</sub> = 0.774, &#x003BB;<sub>3</sub> = 0.779, and &#x003BB;<sub>4</sub> = 0.662.</p>
</sec>
<sec>
<title>Personality</title>
<p>Children&#x00027;s personality was assessed as an external report. To do so, a version of the <italic>Big Five Inventory</italic> (BFI) by John and Srivastava (<xref ref-type="bibr" rid="B24">24</xref>) for parents to describe their children&#x00027;s personality was used. Here, a German version of this questionnaire was applied. For this, the English version of the parental BFI was translated into German and independently back-translated into English. The German translation was oriented toward the German BFI self-report by Rammstedt and Danner (<xref ref-type="bibr" rid="B25">25</xref>). The parental BFI consists of 46 items that are answered on a five-point Likert scale (1 = &#x0201C;disagree strongly&#x0201D; to 5 = &#x0201C;agree strongly&#x0201D;). Mean scores were calculated for the five personality dimensions extraversion (8 items, &#x003B1; = 0.81), agreeableness (9 items, &#x003B1; = 0.75), conscientiousness (9 items, &#x003B1; = 0.88), neuroticism (8 items, &#x003B1; = 0.83), and openness to experiences (10 items, &#x003B1; = 0.75). The two remaining items of the parental BFI measure the scale liking, which was not of relevance for the present work. A CFA with an ML estimator was performed. The model fit for the proposed factor structure of the parental BFI was in the lower range of acceptability [&#x003C7; <sup>2</sup>(892) = 2,871.060, <italic>p</italic> &#x0003C; 0.001; CFI = 0.763; TLI = 0.748; RMSEA = 0.067; SRMR = 0.091].</p>
</sec>
<sec>
<title>Control Variables</title>
<p>Parents&#x00027; age as well as children&#x00027;s age and gender were considered as control variables. It was not possible to control for parents&#x00027; gender due to the high number of participating mothers.</p>
</sec>
<sec>
<title>Statistical Analyses</title>
<p>All variables of interest were checked for normal distribution by Shapiro&#x02013;Wilk tests. As none of the variables followed a normal distribution (see <xref ref-type="table" rid="T1">Table 1</xref>), only non-parametric tests were performed. Tests for control variables were Spearman rank correlations, a &#x003C7;<sup>2</sup> test of independence, and Mann&#x02013;Whitney <italic>U</italic>-tests. All significances were tested two-tailed. As parent&#x00027;s age, children&#x00027;s age, as well as children&#x00027;s gender were associated with some variables of interest, these variables were controlled in further analyses if this was possible. Associations between children&#x00027;s personality and GDT scores were analyzed <italic>via</italic> partial Spearman rank correlations (controlled for children&#x00027;s age), separately for boys and girls and for reasons of completeness also for boys and girls together. Given the directed hypothesis, correlations with neuroticism and conscientiousness were performed one-tailed; correlations with extraversion, agreeableness, and openness to experiences were performed two-tailed instead. With &#x003C7;<sup>2</sup> tests of independence, it was investigated if general parental and childhood gaming were independent of each other (two-tailed tested, no control for age and gender possible). While doing so, one &#x003C7;<sup>2</sup> test was conducted in the independent replication subsample of <italic>n</italic> = 244, which was not included in Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>). Another &#x003C7;<sup>2</sup> test was conducted in the total sample of <italic>N</italic> = 493. Finally, to check for associations between parents&#x00027; and children&#x00027;s tendencies toward GD partial Spearman rank correlations were performed separately for boys and girls and for reasons of completeness also for boys and girls together (controlled for parents&#x00027; and children&#x00027;s age; one-tailed tested). Again, correlation analyses were performed twice: once in the independent replication subsample, which was not included in Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>), and once in the total sample. As for these correlation analyses solely parents and children who were playing video/computer games were of relevance, the respective subsamples are smaller than in the remaining analyses.</p>

<title>Gaming and Personality in Children</title>
<p>As hypothesized, within the total sample of playing children (boys and girls were analyzed together), the GDT score was significantly positively correlated with neuroticism but significantly negatively correlated with conscientiousness. Moreover, associations between the GDT score and extraversion, agreeableness, and openness to experiences were exploratory analyzed. These three personality dimensions were all significantly negatively correlated with the GDT score.</p>
<p>Regarding gender differences, for boys, the GDT score was significantly positively correlated with neuroticism but significantly negatively correlated with conscientiousness, extraversion, agreeableness, and openness to experiences. For girls, the correlation between the GDT score and neuroticism was significantly positive. The remaining correlations were negatively directed but were not statistically significant. After Bonferroni correction for multiple testing to &#x003B1; of 0.0033 (0.05/15), most of the correlations remain statistically significant. All correlations of the GDT score with personality traits are presented in detail in <xref ref-type="table" rid="T3">Table 3</xref>.</p>

<title>Discussion</title>
<p>The present study investigated the associations between children&#x00027;s tendencies toward GD and their own personality traits as well as their parents&#x00027; gaming behavior.</p>
<p>Regarding personality, it was hypothesized that GD tendencies in children are positively correlated with neuroticism but negatively correlated with conscientiousness. This hypothesis is supported by the data of the current study. Therefore, the found results provide support that the personality traits neuroticism and conscientiousness are of relevance for tendencies toward GD not only in adolescents and adults (<xref ref-type="bibr" rid="B6">6</xref>, <xref ref-type="bibr" rid="B8">8</xref>) but also in children.</p>
<p>Neuroticism is described as emotional instability with a person reacting with negative emotions such as anxiety, anger, or sadness to stressful events (<xref ref-type="bibr" rid="B27">27</xref>). It is assumed that people with high neuroticism use gaming as a maladaptive coping strategy to regulate their negative emotions and/or to deal with negative life events (<xref ref-type="bibr" rid="B8">8</xref>). Gaming might represent a distraction from negative emotions already in children and therefore be a vulnerability factor for GD already at an early age.</p>
<p>Conscientiousness describes a person to have high self-control, accuracy, and self-determination (<xref ref-type="bibr" rid="B28">28</xref>). Especially a lack of self-control might be of relevance for longer and more excessive gaming. But we want to stress that the observed expressions of personality within the present sample are not pathological but in the range of normality. Moreover, especially in children, personality traits change during development, and self-control is developed within late adolescence and early adulthood that results in higher conscientiousness (<xref ref-type="bibr" rid="B29">29</xref>). Therefore, the connection between personality and gaming in childhood in our study only represents a snapshot, and a reduction of tendencies toward GD due to better self-regulation strategies in later childhood is possible.</p>
<p>Interestingly, the positive association between GD tendencies and neuroticism was present in both genders when analyses were conducted separately for boys and girls. For the association with conscientiousness only in boys, a statistically significant correlation was present, while for girls, a non-significant trend in the same direction existed. The lack of significance in the girl sample might be due to two aspects. First, the girls&#x00027; sample was smaller than the boys&#x00027; sample. Second, girls had lower GDT scores but higher conscientiousness scores than boys, wherefore detecting an effect is more difficult in the girls&#x00027; sample compared to the boys&#x00027; sample; especially as the variance within the GDT scores of girls was smaller than in boys. Perhaps the higher conscientiousness scores reflect an earlier maturation process of girls compared to boys, especially as girls were even half a year younger than boys in the present total sample.</p>
<p>Regarding personality, also significantly negative associations between GD tendencies and the personality traits extraversion, agreeableness, and openness to experiences could be observed. As we did not hypothesize these associations, we do not want to overinterpret our findings, but are interested to see if these observations can also be made in future scientific works investigating links between personality and GD in childhood. From what we observe in the present work, children with tendencies toward GD are rated by their parents as being less curious regarding their environment (lower openness to experience), less empathic and cooperative (lower agreeableness), and more introverted (lower extraversion). As the present study is of correlative nature, it is not possible to determine if these manifestations of personality traits are a result of excessive gaming or if these provide a disposition toward GD. In line with the I-PACE model, we would expect the latter to be true (<xref ref-type="bibr" rid="B6">6</xref>); hence, certain constellations of personality traits might make a person more vulnerable toward GD than others. Nevertheless, it is important to keep in mind that personality in children is not necessarily stable but is rather prone to change during development (<xref ref-type="bibr" rid="B29">29</xref>&#x02013;<xref ref-type="bibr" rid="B31">31</xref>). Especially agreeableness and conscientiousness are supposed to increase between early childhood and the first years of elementary school (<xref ref-type="bibr" rid="B32">32</xref>).</p>
<p>Moreover, even though personality is of relevance to understand the etiogenesis of GD, it is only one relevant factor among many. In the present work, we therefore aimed to shed light on a further factor, namely parental gaming, while we especially focused on the relationship between parental and childhood gaming. We hypothesized parental and childhood gaming to be interdependent. The results support this hypothesis as gaming parents were more likely to report that their children are gaming as well. Additionally, the GDT scores of parents and their children were positively correlated with each other. The results replicate the findings by Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>) and other research according to which parental gaming is related to children&#x00027;s gaming behavior (<xref ref-type="bibr" rid="B18">18</xref>, <xref ref-type="bibr" rid="B19">19</xref>). Even if in the present study no statements regarding causality can be made, also on the background of <italic>Social Learning Theory</italic> (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B21">21</xref>), it seems more likely that parents&#x00027; gaming influences children&#x00027;s gaming instead of vice versa. Children are good observers and copy the behavior of their environment and obviously also the behavior of their parents. Therefore, parents should reflect on their own gaming behavior and consider reducing it to prevent their children from developing a problematic gaming behavior or even a GD.</p>
<p>One strength of the present study is the investigation of three potential risk factors that might be related to children&#x00027;s tendencies to GD, namely high neuroticism, low conscientiousness, and parental gaming. Actually, these hypothesized relations were supported by the findings of the present work. This is an important contribution in understanding the etiology of GD. Furthermore, the replication of the findings by Wernicke and Montag (<xref ref-type="bibr" rid="B22">22</xref>) regarding the positive association between parental and childhood gaming is another strength, as independent replications are highly relevant.</p>
<p>But the present study also has some shortcomings. One limiting factor is that frequency and duration of gaming were not assessed, neither for children nor for parents. However, the amount of time spent gaming is not an indicator for GD but clearly accompanies a problematic gaming behavior (<xref ref-type="bibr" rid="B2">2</xref>). Moreover, recent work demonstrates how difficult it is to assess the time spent on technology use <italic>via</italic> self-report (<xref ref-type="bibr" rid="B33">33</xref>). Another limitation is the homogenous parental sample as a vast majority of participating parents were mothers. In future research works, it would be of interest to examine whether the association between parental and childhood gaming differs depending on whether fathers or mothers are investigated. Limitations regarding the interpretation of results also arise from the external report of children&#x00027;s gaming behavior and personality and the self-report of parents&#x00027; gaming. In this realm, it has to be mentioned that some researchers propose to assess temperament instead of personality in children (<xref ref-type="bibr" rid="B34">34</xref>). But personality develops from temperament (<xref ref-type="bibr" rid="B34">34</xref>). Also temperament and personality in children are reported to be rather similar (<xref ref-type="bibr" rid="B35">35</xref>, <xref ref-type="bibr" rid="B36">36</xref>) and to be at least moderately related with each other (<xref ref-type="bibr" rid="B37">37</xref>). Therefore, we considered the assessment of personality traits to be appropriate. Finally, due to the study design, no statements regarding causality are possible.</p>

<title>Conclusion</title>
<p>Gaming&#x02014;hence playing computer and video games&#x02014;is already popular in young children. But there is a risk that children develop an excessive or problematic gaming behavior. Therefore, the present study investigated the relationship between tendencies to GD and two of its possible vulnerability factors: children&#x00027;s personality traits and parental gaming. As in adolescents and adults, higher neuroticism and lower conscientiousness were related to higher GD tendencies in children. Additionally, associations of higher tendencies towards GD with lower extraversion, agreeableness, and openness to experiences were present. But these links of personality traits and GD need to be further investigated regarding their robustness in childhood as these relations were not hypothesized in the present work. Moreover, gaming behavior of parents was positively associated with children&#x00027;s gaming, too. The findings of the study add to the literature that already in children relations between personality traits and gaming behavior exist and that parents&#x00027; gaming behavior can be a vulnerability factor for disordered gaming in children. In the future, research projects with a longitudinal design are of importance to understand the causality behind the reported findings.</p>
