1. Introduction
Aggression refers to an individual's psychological and behavioral tendency to intentionally harm the target of an attack, either directly or indirectly, so that the target suffers a destructive effect[
1]. It is one of the most important measurable indicators of adolescent mental health[
2]. Behavior triggered by aggression is known as aggressive behavior [
1]. Violence triggered by adolescent aggression has been increasing in recent years, which is not only detrimental to the healthy development of adolescents physically and mentally, but also affects the stability of society [
3]. The malicious killing of fellow classmates by three junior high school students in Hebei Province, China, has once again attracted widespread attention. Adolescents are in the "psychological weaning period". They are eager to get rid of parental supervision, try to think and solve problems independently, but when faced with some problems, they may be at a loss and become vulnerable to the influence of other people and external factors. According to Bandura's Social Learning Theory [
4], observational learning and alternative reinforcement are also important methods for individuals to acquire behavior. The emergence of adolescent aggression is not solely due to a single cause but should be examined from multiple perspectives. Therefore, the focus of this study was on the causes of adolescent aggression. We expect to prevent and reduce adolescent aggressive behavior. Thus, promoting adolescents' physical and mental health
Harsh parenting is a series of aggressive parenting styles that parents use with their children. Including outward physical and verbal aggression as well as psychological aggression and forced control behaviors[
5]. Studies have found that harsh parenting is a negative parenting style [
6], in which parents' rough treatment can cause children to lack care, resulting in impeded physical, psychological, and socialization development [7–10]. According to Bandura's social learning theory, parenting styles affect adolescents' perceptions, causing them to mentally and behaviorally imitate their parents' thinking and behavioral patterns during interpersonal interactions [
11]. Studies have shown that harsh parenting has a more serious impact on adolescents in terms of internalization problems and externalization problems. In terms of internalization problems, individuals perceive being treated roughly by their parents as a painful experience. This experience can cause them to be deeply anxious, wary, and upset for a long period of time. It can also impair their ability to regulate their emotions [
12]. This leads to an increased risk of adolescents internalizing aggressive behaviors and developing negative self-perceptions [
8,
13]. It even leads to negative emotional experiences such as depression and social anxiety in adolescents [
14,
15]. In terms of "externalization", harsh parenting is not only directly related to aggressive and destructive behaviors in adolescents, but even has an impact on delinquent behavior and substance abuse in adolescents [
16,
17]. Harsh parenting can lead to adolescents having less control over excessive emotions and excessive behaviors [
18]. As a result, adolescents may engage in aggressive behavior when they encounter problems. In the problem of school bullying, which has been widely concerned by society in recent years, the abusive behavior of bullies is also believed to have the reason of imitating parents' problem solving through violence or other rough behaviors [
19]. Related studies have shown that there are gender differences in the effects of harsh parenting on adolescents. Specifically, harsh parenting by fathers is associated with aggressive behavior in boys, while harsh parenting by mothers is associated with verbal aggression in both boys and girls [
20]. Harsh parenting may make adolescents feel neglected, disrespected, or helpless, impairing the development of individual volitional control, which leads to the acquisition of poor emotion regulation strategies, ease of problem solving in the presence of anger [
21], and increase the risk of aggressive behavior. Based on this, the present study proposes Hypothesis 1: Parental harsh parenting is a positive predictor of adolescent aggression.
As one of the most popular recreational activities among teenagers, online games attract teenagers to spend a lot of time and energy to participate in them [
22]. According to the 52nd Statistical Report on the Development of the Internet in China, as of June 2023, there were 550 million online game users in China, accounting for 51.0 % of the total number of Internet users[
23] . Meanwhile, Zhang 's study also showed that China's adolescents have a serious problem of internet gaming disorder[
24]. Internet gaming disorder is a phenomenon of impaired social and psychological functioning due to prolonged addiction to online games [
25]. Social Learning Theory states that, family factors are important environmental factors affecting adolescents' internet gaming disorder [
26], and parents' behaviors are predictive of adolescents' internet gaming disorder behaviors. Studies have shown that parental harsh parenting can significantly and positively predict adolescent game addiction[
27,
28] , and adolescents who suffer from parenting styles containing forms of violence such as corporal punishment often gain a sense of achievement and satisfaction from online games, which makes them identify with online games [
29], leading to an elevated risk of their internet gaming disorder [
30,
31]. Adolescents with Internet addiction show higher aggressive tendencies than those without Internet addiction [
32], which suggests that Internet game addiction is significantly and positively correlated with aggression in adolescent populations [
33,
34]. Among them, children addicted to violent video games showed significantly higher aggression than adolescents addicted to other games [
35], and the level of violence of video games had a significant positive predictive effect on player aggression [
36]. This addiction may have negative psychological and behavioral effects on adolescents, including an increased likelihood of aggressive behavior. The following hypothesis is proposed: H2: Adolescent internet gaming disorder mediates the relationship between harsh parenting and adolescent aggression.
Incarnation identity is a psychological phenomenon in which an individual's self-perception, experience of presence, emotions and attitudes are temporarily altered in the process of using and experiencing a game avatar, based on the evaluation of the similarity between the avatar and the individual, the attraction to the individual and the degree of fulfillment of psychological needs [
37]. Incarnations in games often have unique attributes and abilities and allow players to interact with other players through the characters they play [
38]. Social Learning Theory suggests that, adolescents who have been in harsh parenting environments for a long period of time may tend to choose avatar characters with more aggressive and conflict-resolving styles, and individuals who identify more with their game avatars will see the avatars as their role models and will learn from and mimic their avatars' behaviors [
39]. When adolescents develop a strong identification with their avatars, they may carry the traits and behavioral patterns of the character into real life. If the chosen character has aggressive or violent tendencies, this avatar identification may negatively affect the adolescent's behavior and increase the likelihood of displaying aggressive behavior.Fische et al. showed that in aggressive games, avatars with a higher similarity to the individual caused players to display higher levels of aggression compared to general avatars [
40,
41]. The following hypothesis is proposed: H3: Adolescent avatar identification mediates the relationship between harsh parenting and adolescent aggression.
Online games have become a way of entertainment and relaxation for many people. However, for some adolescent gamers, online games have become an obstacle in their lives, leading to a great impact on their socialization, study and life in reality. fMRI findings by Ganesh et al. showed that internet gaming disorder and avatar identification were significantly positively correlated [
42], and gamers regarded game avatars as familiar animated characters , thus showing higher identification with game avatars and stronger identification with game avatars. Characters and preferentially identify with the game avatars [
43], thus showing higher identification and stronger emotional involvement with the game avatars [
42]. Compared to non-internet game addicts, internet game addicts have a higher level of identification with game avatars [
44], which further deepens their involvement in the virtual world and gaming community [
45,
46]. Social learning theory suggests that individuals learn by observing and imitating the behavior of others, and if adolescents are surrounded by violent behavior while growing up, they may be inclined to imitate and display similar aggressive behavior. Research has shown that the top online games in terms of number of players, best sellers, and profitability contain aggressive content, especially role-playing games and shooters [
47]. Adolescents who are addicted to such online games may be highly identified with the characters in such games, which in turn may exacerbate the effects of violence in these games on adolescents' aggression [
48]. The following hypothesis is proposed: H4: internet gaming disorder and avatar identification act as chain mediators between harsh parenting and adolescent aggression.
2. Materials and Methods
Using random sampling method, 985 adolescents in Shandong Province were randomly selected as subjects, and 973 questionnaires were retained after invalid questionnaires were excluded. The effective recovery rate was 98.78%, and the collected data were statistically analyzed by SPSS25.0 and Amos26.0 software.
Assessment of harsh parenting scale (AHPS)
This study used the harsh parenting scale developed by Wang (2017) [
20]. The scale is a single dimension with a 5-point scale, "never like this", "seldom like this", "sometimes like this", "sometimes like this", "always like this", and a total of 4 questions, and the higher the total score, the higher the degree of harsh parenting was rated by the adolescents respectively. ", "Often", "Always" are scored from 1 to 5, and there are 4 questions in total. Adolescents evaluated their mothers and fathers separately, and the higher the total score, the more serious the degree of parental harsh parenting was. The Cronbach’s the scale used in this study was found to be 0.875.
Internet Gaming Disorder Scale (IGDS)
In this study, the internet gaming disorder Scale developed by Petry (2014) was used[
49], which consists of 9 items and is a single dimension with a 5-point scale, with scores of 1-5 representing "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", "not at all", and "at all". "The higher the scale score, the more serious the degree of addiction to online games. The Cronbach’s the scale used in this study was found to be 0.937.
Player-Avatar Identification (PAI)
In this study, we used the Incarnation Identification Scale developed by LI (2013)[
50], which is divided into four dimensions, namely, emotional experience during gameplay, concentration during gameplay, positive attitudes toward the incarnation, and the importance of the incarnation to self-identification, and was scored on a 5-point scale, with "not at all conforming" being scored as 1 point, 2 points for "relatively unconformity", 3 points for "somewhat conformity", 4 points for "relatively conformity", and 5 points for "full conformity", for a total of 5 points. " counts 5 points, a total of 15 questions, calculate the total score, the higher the score, the deeper the degree of incarnation identity. The Cronbach’s the scale used in this study was found to be 0.965.
Chinese College Students' Version of Buss-Perry Aggression Questionnaire (CC-BPAQ)
In this study, we used the Buss-Perry aggression scale revised by Lu et al. (2013)[
51], which is divided into four subscales, namely hostility subscale, impulsivity subscale, physical aggression subscale, and irritability subscale, with a total of 22 items, and scored using a 5-point scale, with the scores of "very much not in line" "fairly noncompliant," "average," "fairly compliant," and "very compliant," respectively, on a scale of 1-5, with the higher score The higher the score, the more aggressive. The Cronbach’s the scale used in this study was found to be 0.945.
4. Discussion
This study focuses on the effects of harsh parenting on adolescent aggression and explores the mechanisms by which internet gaming disorder and avatar identification play a role.
The results of this study indicate that severe parenting styles have a significant positive predictive effect on adolescent aggression. The more severe the parents' harsh parenting style, the higher the adolescents' level of aggression, which validates this study's H1. Harsh parenting in the family environment will increase the risk of individuals developing aggressive behaviors, which is in line with the obsessive-compulsive hypothesis proposed by Petterson (1982). This is consistent with Petterson's (1982) hypothesis that parental harsh parenting and controlling behaviors lead to adolescents' irritability and aggression in the face of parental harsh parenting, and that the cycle may even lead to adolescents' transgressive behaviors. On the one hand, harsh parenting leads to a tense family atmosphere, which puts adolescents in a state of insecurity [
12], impairs the development of volitional control [
53], and makes adolescents more sensitive to negative evaluative messages from others and threatening stimuli in the environment, leading to an increased risk of internalizing adolescent aggression [
54,
55]. On the other hand, adolescents who are chronically exposed to harsh parenting not only develop a tendency to attribute hostile intentions to ambiguous social interactions [
56,
57]. This increases the risk of maladjustment in adolescents. Poor emotion regulation strategies are also learned. Solving problems through aggressive behavioral displays such as expressing anger [
58]. Conflict and violence in the family environment may serve as a model for children to learn aggressive behaviors, and they may learn aggressive ways of resolving conflicts by observing and imitating the behaviors of their parents or other family members, which validates social learning theory. The results of this study reaffirm that harsh parenting styles are a direct predictor of adolescent aggressive behavior. The harsher the parenting style adopted by the parents, the more aggressive the adolescents were.
The results of this study suggest that Internet Game Addiction has a significant mediating effect between harsh parenting and adolescent aggressive behavior. Harsh parenting styles can influence adolescent aggression through online gaming disorders, which supports H2. In this study, adolescent internet gaming disorder was positively correlated with both parental harsh parenting and adolescent aggression, which is in line with the results of a previous study by Yu [
59]. They found that adolescents who suffer from harsh parenting are unable to obtain basic psychological needs from their parents, and thus turn to online games to obtain psychological fulfillment to alleviate their bad moods. Other scholars' studies also confirm that parenting styles, including corporal punishment and scolding, can cause adolescents' rebelliousness. [
24]. Adolescents' minds are still immature and are more vulnerable to the misguidance of online games, especially adolescents who are addicted to violent online games will have a stronger tendency to aggression [
60]; most of the individuals who grow up under harsh parenting will also tend to resort to behaviors such as persecution and aggression when solving problems [
5], and online games will often be used in such a way that the players will be successful after successfully rewarded accordingly after solving problems, so that they will adopt aggressive ways to solve similar problems when facing them, which is consistent with Skinner's reinforcement theory. This result was confirmed by a related study by He and Li.The view of life of adolescents who have been addicted to online violent games for a long time will be distorted, blurring the boundaries between the real society and the virtual world, and the violent orientation of online games not only increases adolescents' aggressiveness, but also may even lead to adolescents' delinquent behaviors [
61], which is also in line with the viewpoints of the social learning theory. Individuals who grow up under the environment of harsh parenting are more likely to be addicted to online games when their basic psychological needs are not met, and under the combined influence of harsh parenting for a long period of time and the worldview of solving problems with violence in online games, adolescents' aggressiveness will be enhanced, and they will be more likely to adopt aggressive solutions when encountering problems. internet gaming disorder is an important way in which parental harsh parenting affects adolescent aggression.
The results of this study indicate that avatar identity is significantly and positively related to both harsh parenting and adolescent aggression. And it mediates the relationship between harsh parenting and adolescent aggression. Harsh parenting influences adolescent aggression through avatar identity, which validates this study's H3.According to Self-Discrepancy Theory [
62], individuals who are dissatisfied with their lives have higher levels of level of real-ideal self-discrepancy, and by choosing avatars that are not similar to themselves and have ideal qualities, they can reduce their self-discrepancy by shifting their focus from the unpleasant or unsatisfactory real world to the virtual world that satisfies them [
63]. Parental harsh parenting can cause children to develop self-discrepancies and thus be more inclined to build their ideal selves through online gaming, and identifying with a gaming avatar may be a way to reduce gamers' real-ideal self-discrepancies and negative emotions [
43,
64]. harsh parenting environments can lead to biases in adolescents' social cognition [
65], affecting the formation and stabilization of their individual identities. Studies have shown that self-perception has a significant impact on an individual's choice of gaming avatars, and harsh parenting leads children to develop negative self-perception [
8].Adolescents with negative self-perception have a lower sense of self-esteem, and when choosing gaming avatars, they are more inclined to choose avatars that are similar to their ideal selves [
66]. Incarnate identification causes adolescents to have more emotional involvement with game avatars [
42], affects adolescent aggression perceptions and self-concept [
48], and amplifies adolescent hostility [
67]. As a result, players with high levels of avatar identification exhibit higher levels of aggression [
40]. Incarnate identification is an important influence between harsh parenting and adolescent aggression.
The results of this study indicate that there is a significant chain mediation between online gaming disorder and avatar identity between strict parenting and adolescent aggression. Harsh parenting influences adolescent aggression by affecting online gaming disorder and avatar identity, which supports this study's H4. Smahel also showed that online game addicted gamers showed a stronger avatar identification as compared to other gamers [
44]. Individuals who identify more strongly with a game avatar for the same game character show characteristics more similar to the avatar [
68]. Individuals who are addicted to violent video games, and who themselves display aggressive behavior in reality, incarnate identification amplifies the effects of the online game, resulting in increased aggression [
39]. This is consistent with the social learning theory that adolescents who are addicted to online games will be interested in viewing the game characters as their role models and will mimic the behavioral patterns of the game characters, and that adolescents who identify with the aggressive characters will display increased aggression.
Therefore, reducing adolescent aggression can be achieved by changing the original harsh parenting style of parents to a more democratic and warm parenting style, as well as by increasing real-life activities such as peer interactions and teacher-student interactions among adolescents to reduce adolescents' internet gaming disorders and incarnate identity behaviors, which will in turn reduce adolescent aggression.
Limitations
First, it is important to emphasize that these are theoretical ideas and do not mean that every individual will be affected in the same way. Harsh parenting, online gaming addiction, and avatar identification may vary depending on an individual's background, environment, and other factors. In addition, there are other factors that may be associated with aggressive behavior,s such as mental health issues, social environments, and family relationships. Therefore, understanding and preventing aggressive behavior requires a combination of factors, and future research could conduct qualitative studies with comprehensive interventions.
Second, the results of this study on the effects of internet gaming disorder and avatar identification on health are negative, while some studies have shown that both have positive effects on adolescents' healthy development (e.g., good qualities such as friendliness, confidence, etc.). A noteworthy direction for future research might explore the positive effects of internet gaming disorder and avatar identification (e.g., helpful behaviors and promotion of good social interactions).
Finally, the results of this study can only be generalized to adolescents who are of the same ethnicity and have the same cultural background as the subjects of this study; future research could conduct comparative studies with ethnic minority adolescents as the subjects, and could also try to conduct cross-cultural studies for groups of adolescents with different cultural backgrounds.
