1. Introduction
Smartphone dependency refers to the occurrence of excessive smartphone usage, wherein individuals find themselves unable to control their behavior even in public settings where phone use is prohibited, leading to adverse impacts on both their social and personal lives [
1]. In comparison to adults, adolescents exhibit heightened sensory needs, necessitating a greater influx of external stimuli to achieve optimal arousal levels [
2]. Smartphones, serving as multifaceted sources of leisure, entertainment, and social connectivity, provide adolescents with ample avenues for sensory gratification. Due to the incomplete development of self-regulatory capacities among adolescents, they are more susceptible to smartphone dependency, resulting in unfavorable psychological outcomes such as diminished concentration, impaired memory, and emotional issues [
3,
4]. Consequently, researchers have placed significant emphasis on the predicament of adolescent smartphone usage.
Previous research has identified numerous factors that influence adolescent smartphone dependency, including the intrinsic attributes of the devices, adolescent personality traits, family dynamics, peer relationships, and environmental factors [5-8]. Among these, family factors hold particular significance. In recent years, scholars have increasingly focused on the pervasive phenomenon of parental phubbing within the family context. Parental phubbing is defined as parents directing their attention towards smartphones during parent-child interactions, thereby neglecting or disregarding their children [
9]. Researchers have found that such behavior poses a threat to the mental and physical well-being of adolescents. When parental phubbing is more prevalent within the family, adolescents are more likely to experience symptoms such as depression, poor sleep quality, academic procrastination, peer detachment, and even suicidal tendencies [9-13]. A series of studies indicate that parental phubbing can positively predict adolescent smartphone addiction, with factors like parent-child bonding, deviant peer associations, and tendencies towards boredom serving as mediating mechanisms [
9,
14,
15]. Notably, Wang and colleagues further discovered that parental phubbing not only impacts adolescent smartphone dependence but also extends its influence to academic performance [
16]. Based on the Parental Acceptance-Rejection (PAR) Theory [
17], early experiences of perceived parental acceptance or rejection influence a child's emotional, behavioral, and socio-cognitive development [
18], with these effects persisting into adolescence and even adulthood. Parental phubbing results in adolescents feeling neglected in terms of positive attention and emotional feedback, and smartphones become a primary means for them to seek emotional gratification. Adolescents who have experienced rejection by their parents may be more susceptible to developing psychological issues [
19,
20], such as smartphone addiction.
In prior research endeavors, the measurement of parental phubbing has predominantly relied upon the child's perception, with little attention afforded to investigating the parents' own perception of their engagement in such behavior. Consequently, does a perceptual discrepancy concerning parental phubbing exist between the parent-child dyad? Within the realm of developmental psychopathology research, the evaluation of family or parental contributions relevant to child psychopathology often entails the utilization of multi-informant reports. Participants typically encompass children, parents, teachers, peers, and clinical professionals, with the reports encompassing diverse facets such as academic performance and criminal records. However, discrepancies in these reports are not uncommon, manifesting as perceptual discrepancies, where disparate individuals possess contrasting subjective perceptions of a shared objective entity [21-24]. Drawing upon this backdrop, we posit Research Hypothesis 1: There may exist perceptual discrepancies regarding parental phubbing between parents and their children.
If there exists a perceptual discrepancy between parents and adolescents regarding parental phubbing behavior,
could this perceptual discrepancy serve as another factor influencing adolescent smartphone dependence? De Los Reyes and Ohannessian introduced the "Discrepancy-Maladaptive" hypothesis [
25]. This theoretical framework posits that the "discrepancy" observed in the parent-child dynamic is indicative of parents' limited insight into the genuine circumstances of their offspring, which consequently leads to an inadequate appreciation of the child's subjective perceptions. Within such a paradigm, adolescents are more predisposed to adverse developmental outcomes, which commonly encompass behavioral, emotional, social adaptive, and academic domains [
21,
23,
25]. Presently, studies rooted in this hypothesis predominantly center on the realm of perceived disparities in parenting styles. Notably, positive parenting behaviors are typically less recognized by adolescents than by their parents, while negative parenting behaviors are often perceived in excess by adolescents in comparison to parental recognition. Such dynamics are correlated with a heightened susceptibility to negative developmental outcomes encompassing externalizing behaviors, emotional perturbations, social adaptation challenges, and compromised academic achievements [21,26-28]. Some scholars contend that the predictive efficacy of parent-child perceptual discrepancies on developmental outcomes might surpass the impact of parenting styles reported solely by adolescents [
29]. Parallel to these notions, parental phubbing can be conceived as a form of negative parental behavior, and adolescent smartphone dependence, a manifestation of externalizing problem behavior. In light of this context, we posit
Hypothesis 2 : Perceptual discrepancies regarding parental phubbing positively predict adolescent smartphone dependence.
Furthermore, if the perceptual disparities regarding parental phubbing indeed prove to be an influencing factor on adolescent smartphone dependence,
what mechanistic pathways underlie this phenomenon? Within the familial milieu, the parent-child relationship occupies a pivotal centrality. The dynamics of interaction and emotional resonance between parents and their offspring wield substantial influence on the adolescents' prospective social interactions. According to attachment theory, establishing secure attachment bonds with parents can provide adolescents with a foundation of nurturing support [
30]. In contradistinction, the failure to cultivate such secure attachment bonds augments the susceptibility to psychological and behavioral maladies among adolescents, rendering them predisposed to the grip of smartphone addiction [
31]. Qualitative interviews have revealed that many full-time mothers cite their use of electronic devices at home as a means of temporarily escaping the monotony and frustrations of parenting, seeking respite from the burdens of domestic minutiae [
32]. Anchored in these insights, parental phubbing is deemed a manifestation of negative parenting conduct, encompassing practices such as harsh discipline, neglect, dishonesty, and disregard. Drawing from the "Discrepancy-Maladaptive" hypothesis, When there is a perceptual discrepancy between parents and adolescents regarding parental phubbing behavior, adolescents may develop dissatisfaction towards their parents. This, in turn, could potentially trigger an avoidance attachment strategy, resulting in impoverished communication quality, diminished trust, and ultimately, a decline in the quality of the parent-child attachment bond. Hence, we posit
Hypothesis 3 : The perceptual discrepancies regarding parental phubbing significantly negatively predict the parent-child relationship quality. Concurrently, a substantial body of research has substantiated that parent-child relationships exhibit a significant negative predictive capacity concerning adolescent smartphone dependence. Adolescents embedded within harmonious parent-child relationships exhibit lower levels of smartphone dependence [
31,
33]. In summation, we advance
Hypothesis 4 : The parent-child relationship acts as a mediator between the perceptual discrepancies regarding parental phubbing and adolescent smartphone dependence.
The present study aims to investigate the impact of perceptual disparities regarding parental phubbing on adolescent smartphone dependence, subsequently delving into the mediating role of the parent-child relationship. The theoretical framework delineated by the mediation model is graphically depicted in
Figure 1. Amid the panorama of adolescent demographics, middle school students stand as a distinctive cohort characterized by a juxtaposition of nascent adult-like cognitions and residual immaturity. This paradox engenders a potent sense of independence within them, often accompanied by an emotional ambivalence in their interactions with adults. Consequently, middle school students forge an increasingly robust rapport with the digital realm. Concurrently, their psychological dependence on parental figures remains a salient facet. Parental understanding, support, and protection continue to wield significance in their lives. Hence, this study centers its focus on the middle school student demographic.
