Children and adolescents are a particularly high-risk population for the development of anxiety symptoms (Lin et al., 2024; Rapee et al., 2023), although the age of onset and development of the different forms of anxiety disorders (e.g., specific phobia, panic disorder, separation anxiety, etc.) tends to vary widely (Ohannessian et al., 2017; Rapee et al., 2023). Generalized anxiety disorder (GAD) is one of the most common anxiety disorders in adolescence and tends to occur in the transitional period between late childhood and early adolescence (Beesdo-Baum and Knappe, 2012; Ohannessian et al., 2017). GAD is a syndrome characterized by the experience of excessive, uncontrollable worry about various life circumstances (American Psychiatric Association, 2013). This disorder has a significant impact on the psychological and social functioning of adolescents and tends to become chronic and extend into adulthood (Crocetti et al., 2015).

Central to the worries of people with GAD are social-evaluative concerns in interpersonal interactions (Hudson and Rapee, 2004). This has led clinicians and researchers to focus on the close relationships of affected adolescents, and in particular the quality of their relationship with their parents, when investigating the onset of GAD symptoms. Indeed, despite the fact that during adolescence the individual experiences greater autonomy and the peer group becomes the main referent for emotional support, parents continue to exercise an important function in early adolescence and influence their psychological adjustment (Badenes-Ribera et al., 2019; Sechi et al., 2020). In this study, we will attempt to extend the current knowledge on the association between parental rejection (an emotionally abusive form of parenting experienced by children and characterized by a cold, neglectful, hostile or rejecting parental relationship) (Rohner, 2021) and the risk of developing GAD symptoms in a sample of early adolescents. In addition, our study will attempt to expand the current knowledge of the possible mechanisms involved in this relationship. Considering that several studies report that subjects with GAD tend to have difficulties in recognizing and regulating their emotions (Paniccia et al., 2018), and considering that this emotional competence has its roots in a close, warm and supportive relationship with parents, our study will investigate the possible role of alexithymia. Along these lines, we will seek to explore the possible mediating role of alexithymia in the relationship between both maternal and paternal parental rejection and GAD.

Low quality of the relationship with parents appears to be a risk factor for the development of GAD symptoms in adolescence. In general, insecure attachment is considered a risk factor for anxiety disorders, and this association appears to be stronger in early adolescence (Colonnesi et al., 2011). One factor that negatively shapes the perception of the quality of parental relationships and promotes insecure attachment to the caregiver is parental rejection (Ildiz and Ayhan, 2020). According to the Interpersonal Acceptance-Rejection Theory (IPARTheory; Rohner et al., 2005), “parental warmth” is a key factor in promoting positive psychological adjustment in children, adolescents and adults. According to this theoretical perspective, “parental acceptance” is at one end of the warmth dimension, while “parental rejection” is at the other end (Rohner et al., 2005). Parental acceptance encompasses the warmth, affection, love and interest that parents show toward their children, while parental rejection describes the situation in which parents do not accept or want their children and perceive them as a burden (Rohner et al., 2005). Parental acceptance is expressed by parents with behaviors such as hugging, kissing, stroking, comforting and saying positive words. Parental rejection, which is conceptualized as a form of abuse, is expressed through behaviors such as coldness, deprivation of love, neglect, physical injury, humiliation, and criticism. According to theorists, parental rejection can be experienced by children as a combination of the following expressions: cold and unaffectionate, hostile and aggressive, indifferent and neglecting and undifferentiated rejecting (Khaleque and Rohner, 2012). Adolescents who have experienced rejection in the parental relationship tend to develop a more negative view of self-image and the social world and report a higher risk of developing psychological symptoms (Mendo-Lázaro et al., 2019; Khaleque and Rohner, 2002). Longitudinal evidence from different cultural contexts seems to indicate that both maternal and paternal rejection predict increased internalizing symptoms in adolescence (Rothenberg et al., 2022). In particular, some data suggest that parental rejection is significantly associated with increased GAD symptoms (Hale et al., 2006; Knappe et al., 2022). Overall, it is possible that a low quality of relationship with parents, characterized by a low level of affection and a high level of criticism and rejection, leads individuals to feel unsupported and unloved, establishing in them a negative self-perception and beliefs related to the risk of being rejected and abandoned by others (Badenes-Ribera et al., 2021; Colonnesi et al., 2011). In this way, the experience of parental rejection can be internalized by the individual, developing not only a negative self-image but also a negative expectation toward others, thinking that others will be prone to abandonment and rejection (Knappe et al., 2022), which fuels the anxious worries typical of GAD. This aspect is particularly evident in early adolescence, where the need for belonging and acceptance plays a key role in psychological adjustment processes (Fabris et al., 2024). However, one should be cautious in assuming a strict linear causal relationship between parental rejection and GAD, as some longitudinal studies suggest that GAD is a predictor of perceived parental rejection in adolescents (Hale et al., 2011; Nelemans et al., 2014). In this sense, it is possible that psychopathological symptoms influence self-perception in adolescents with GAD. For these adolescents, a negative self-evaluation could lead them to process social interactions in a way that is consistent with their self-worth, and therefore to perceive their relationship with their parents as more negative, critical and rejecting. Along these lines, adolescents could engage in behaviors that are consistent with their perceptions and thus stimulate more negative parental interactions, ultimately reinforcing perceptions of a loveless and negative relationship and thus higher perceived parental rejection (Nelemans et al., 2014).

In this study, we will examine the relationship between GAD symptoms and parental rejection by measuring paternal and maternal rejection separately. The reason for this is that the literature seems to indicate a differential role of maternal and paternal relationship quality in predicting childhood anxiety symptoms (Möller et al., 2016) and GAD in particular (van Eijck et al., 2012). Furthermore, research on parenting has primarily focused on the mother–child relationship, but we know that fathers can make a unique, significant contribution to child and adolescent development (Miranda et al., 2016). In addition, mothers and fathers may have different parenting attitudes and styles, and the literature seems to indicate that experienced parental dissimilarity in terms of emotional warmth or rejection has been linked to the development of internalizing problems (Miranda et al., 2016). Last but not least, although there is evidence for the association between low perceived parental relationship quality and GAD, few studies have specifically examined parental rejection in early adolescents. Furthermore, although theoretical and empirical evidence supports a possible link between GAD and parental rejection, research is still needed to understand what mechanisms might explain this link. In this vein, our study aims to test the possible mediating role of alexithymia in explaining the relationship between perceived maternal/paternal rejection and GAD symptoms in early adolescence.

To substantiate the subsequent results derived from theoretical assumptions, the initial analysis focuses on examining the relationship between parental rejection (from both mother and father) and alexithymia, as presented in Table 1.

Both the relationship with the father and the mother has a significant negative relationship with alexithymia and its specific subdimensions. The higher the level of acceptance of both the mother and the father, the lower the level of alexithymia among adolescents. Interestingly, the strength of dependency in the relationship with the mother is only slightly higher than in the relationship with the father, suggesting an important role for fathers in the development of the child’s emotional competence. The result for the externally oriented thinking is noteworthy, as it is not significant. However, the dimension related to the lack of importance of emotions is significant. Similar to the other dimensions, this one also shows higher levels when parental acceptance is lower (Table 1).

Another important result from the perspective of the corroboration of the theoretical model is the significant relationship between parental rejection and GAD symptoms among adolescents. The strength of the acceptance/rejection relationship with the mother is greater, but the relationship between the relationship with the father and the symptoms of GAD is also statistically significant.

Finally, it is crucial to mention the strong relationship between GAD and the level of alexithymia and its dimensions outside of the externally oriented thinking. These results confirm that alexithymia, which is also significantly associated with parental rejection, may be an important factor in the development of anxiety disorders among adolescents (Paniccia et al., 2018). Lastly, it is worth noting that the relationship between the age of the participants and the other variables is insignificant, with the exception of the DDF dimension, which correlates with age at a positive, low level (Table 1).

Moving on to the confirmation of the theoretical model, the mediating role of alexithymia in the relationship between parental rejection (from both mother and father) and the symptoms of GAD is examined. The validation of the model was divided into two stages.

The first involves checking whether the overall level of alexithymia mediates the relationship between rejection by the mother or father and the symptoms of GAD, while the second focuses on identifying which dimension of alexithymia serves as the strongest mediator in each relationship.

The first model for the mediating role of alexithymia in the relationship between levels of rejection/acceptance in the relationship with the mother and the intensity of GAD symptoms is well fitted to the data F (2.220) = 87.47; p < 0.001 and explains 44.3% of the variability in GAD symptoms (Figure 1). The dynamic of acceptance/rejection in the relationship with the mother serves as a protective factor against the development of GAD (c = −0.34; p < 0.05). The same is true for the acceptance/rejection relationship with the mother with the level of alexithymia (a = −0.35; p < 0.05) (Figure 1).

On the other hand, the higher the level of alexithymia, the greater the risk of developing GAD (b = 0.61; p < 0.001). After incorporating alexithymia into the model, the strength of the relationship between acceptance/rejection in the relationship with the mother decreased but remained significant (c´ = −0.12; p < 0.05) (Figure 1). The mediation analysis can be considered partial and significant, which is confirmed by the results of the indirect and total effect b = 0.16, 95% CI [−0.22; −0.10]; b = 0.22, 95% CI [−0.28, −0.14].

The second model, examining the mediating role of alexithymia in the relationship between rejection/acceptance in the relationship with the father and the severity of GAD symptoms, also fits the data well F (2.220) = 84.41; p < 0.001 and explains 43.4% of the variability in GAD symptoms (Figure 2).

The levels of acceptance/rejection in the relationship with the father acts as a protective factor in development of GAD (c = −0.26; p < 0.05) (Figure 2). The same is true for the relationship between acceptance/rejection in the relationship with the father and the level of alexithymia (a = −0.30; p < 0.05) (Figure 2). On the other hand, the higher the level of alexithymia, the greater the risk of developing GAD (b = 0.64; p < 0.001). After introducing alexithymia into the model, it turned out that the relationship between acceptance/rejection in the relationship with the Father declined to an insignificant level (c´ = −0.07; n.s.) (Figure 2). The mediation analysis can be considered full and significant, which is confirmed by the results of the indirect and total effect b = 0.11, 95% CI [−0.16; −0.06]; b = 0.19, 95% CI [−0.27, −0.12].

Comparing both models of mediation for the relationship with the Mother and the Father, it is important to highlight that acceptance/rejection in the relationship with the mother is a stronger protective factor in relation to alexithymia and GAD. However, the model for acceptance/rejection in the relationship with the father turned out to be a full mediation, while for the relationship with the mother it was only partial mediation.

After presenting mediation models that took into account the overall level of alexithymia, a number of models were validated to see which dimension of alexithymia would prove to be the strongest mediator. The importance of this analysis stems from the fact that the version of the instrument used for adolescents evaluates four subdimensions of alexithymia, in contrast to the three assessed by most standard versions. At this stage, four separate mediation models were tested to examine the relationship between maternal rejection and symptoms of generalized anxiety disorder (GAD), each model incorporating one of the alexithymia subdimensions (difficulty identifying feelings, difficulty describing feelings, externally oriented thinking, and Lack of subjective significance or importance of emotions) as a potential mediator.

At this stage, four mediation models were tested for the relationship between mother rejection and GAD, with the mediating role of alexithymia subdimensions. All models were found to be significant, respectively for DIF F (2,220) = 98.39, p < 0.001; 47%, DDF F (2,220) = 49.58, p < 0.001; 31.1%, LSS F (2,220) = 31.24, p < 0.001; 22.1%, and one model for EOT was also significant F (2,220) = 14.02, p < 0.001; 11.3%.

However, due to the absence of a statistically significant association between this dimension and generalized anxiety disorder (GAD), it cannot be regarded as theoretically meaningful. Nevertheless, for comparative purposes with alternative models, the associations involving the EOT dimension as a mediator are described and reported (Figure 3). Subsequently, the relationship between acceptance/rejection in the relationship with the mother and specific dimensions of alexithymia was examined, as illustrated in Figure 3. The results indicate significant associations for DIF (a1 = −0.33; p < 0.05), DDF (a2 = −0.30; p < 0.05), EOT (a3 = −0.14; p < 0.05), and LSS (a4 = −0.16; p < 0.05). As predicted, the strongest acceptance/rejection relationship with the mother was found to be for DIF and DDF. Then, the relationship between the dimensions of alexithymia and the level of GAD symptoms was examined. The strongest relationship was shown for the dimension DIF (b1 = 0.60; p < 0.05). A slightly lower result was obtained for DDF (b2 = 0.47; p < 0.05) and LSS (b4 = 0.33; p < 0.05), and for EOT the association with the level of GAD symptoms was negligible EOT (b3 = 0.01; n.s.) (Figure 3). After the introduction of mediators into the mediation models, the direct maternal acceptance/rejection relationship decreased across each alexithymia subdimension, reaching the following level: DIF c´1 = −0.13; p < 0.05; DDF c´2 = −0.20; p < 0.05; EOT c´3 = −0.34; p < 0.05; LSS c´4 = −0.28; p < 0.05 (Figure 3).

Among the reported associations, as previously noted, the mediation effect of the EOT dimension cannot be considered significant. However, for the remaining three dimensions, partial mediation was observed, as confirmed by the significant indirect and total effects for DIF b = 0.15, 95% CI [−0.22; −0.09], b = 0.21, 95% CI [−0.29, −0.13]; DDF b = 0.10, 95% CI [−0.16, −0.05]; b = 0.14, 95% CI [−0.21, −0.07]; LSS b = 0.04, 95% CI [−0.07, −0.01]; b = 0.05, 95% CI [−0.10, −0.01].

As in the case of acceptance/rejection in the relationship with the mother, four models were also tested in the relationship with the father, three of which were found to be relevant, respectively, for DIF F (2.220) = 94.96; p < 0.001; 46.3%, DDF F (2.220) = 45.47; p < 0.001; 29%; LSS F (2.220) = 24.56; p < 0.001; 18.3%. The model for the EOT dimension is also statistically significant, F (2.220) = 7.96; p < 0.001, explaining 6.8% of the variance. However, due to the absence of a significant relationship between EOT and GAD, it cannot be considered theoretically meaningful. Nonetheless, as in the case of the Mother Acceptance/Rejection model, it will be discussed for comparative purposes (Figure 4). The next step was to examine the relationship between levels of acceptance/rejection in the relationship with the father and specific dimensions of alexithymia, which are outlined as follows: DIF (a1 = −0.27; p < 0.05). DDF (a2 = −0.25; p < 0.05). EOT (a3 = −0.11; p < 0.05) and LSS (a4 = −0.16; p < 0.05) (Figure 4). As predicted, the strongest acceptance/rejection relationship with the father turned out to be for DIF and DDF. Then, the relationship between the dimensions of alexithymia and the level of GAD symptoms was examined. The strongest relationship was shown for the dimension DIF (b1 = 0.65; p < 0.05). A slightly lower result was obtained for DDF (b2 = 0.49; p < 0.05) and LSS (b4 = 0.34; p < 0.05), and for EOT the association with the level of GAD symptoms was negligible EOT (b3 = 0.01; n.s.) (Figure 4). After the introduction of mediators into the mediation model, the direct relationship for father acceptance/rejection decreased for each alexithymia subdimension to the following level: DIF c´1 = −0.08; n.s. DDF c´2 = −0.14, p < 0.05; EOT c´3 = −0.26, p < 0.05; LSS c´4 = −0.20, p < 0.05 (Figure 4). Among all the relationships discussed, one case of full mediation was observed for the DIF dimension, along with two partial mediations for the DDF and LSS dimensions, and not significant mediation effect for the EOT dimension. These conclusions are supported by the significant results of the indirect and total effects for DIF b = 0.10, 95% CI [−0.15; −0.05]; b = 0.18, 95% CI [−0.26; −0.10]; DDF b = 0.07, 95% CI [−0.11; −0.03]; b = 0.12, 95% CI [−0.19; −0.05]. LSS b = 0.03, 95% CI [−0.05; −0.01]; b = 0.06, 95% CI [−0.10; −0.01].

The aim of this study was to investigate the relationship between levels of maternal and paternal rejection and GAD in early adolescents, examining the possible mediating role of alexithymia. To our knowledge, this is the first study to examine the relationship between parental rejection and GAD in a sample of early adolescents and attempts to extend knowledge of a possible mediating factor, namely alexithymia. Early adolescence is a critical developmental period, and individuals at this age appear to be at risk of developing anxiety symptoms, particularly GAD. This anxiety syndrome is one of the main reasons for parents to seek psychological intervention for their children. Given the severe impact of GAD on adolescents’ social and academic functioning, it is important to understand what risk factors and mechanisms may play a role.

Our results show a relationship between parental rejection and the risk of GAD in early adolescents. Specifically, when adolescents report a relationship characterized by low levels of acceptance and high levels of rejection, they tend to report more GAD symptoms. These data are consistent with previous literature identifying parental rejection as a possible risk factor for adolescent psychological adjustment (Khaleque and Rohner, 2012) and are in line with previous studies that have found an association between parental rejection and GAD (Hale III et al., 2006; Knappe et al., 2022). In this sense, it is possible that the experience of parental rejection influences the mental representation that individuals develop of themselves as unlovable and of others as subjects prone to abandonment and criticism, fueling the concerns that increase the risk of developing GAD.

Furthermore, our data show that both maternal and paternal rejection directly and indirectly predicted GAD symptoms. This finding is interesting because it confirms the contribution that both parents could make to the occurrence of GAD. The Acceptance/Rejection theory has received solid empirical support for the role of both parents in predicting psychological adjustment in adolescents and young adults (Miranda et al., 2016; Khaleque and Rohner, 2012), while questions remain about the possible association between maternal and paternal rejection and specific developmental outcomes in children, adolescents and adults (Mendo-Lázaro et al., 2019). While some previous findings tend to distinguish the effects of maternal and paternal parenting on the onset of anxiety symptoms (Beato et al., 2016), our study shows how parental rejection significantly predicts GAD symptoms in both the relationship with the mother and the father. Our data are consistent with previous literature showing an association between internalizing symptoms and parental rejection, both maternal and paternal (Giotsa et al., 2018; Giaouzi and Giovazolias, 2015). The only available evidence on the relationship between parental rejection and specifically GAD symptoms in adolescence has examined only the overall level of perceived parental rejection, and therefore further future research is needed to compare our data with other studies. Furthermore, our study shows not only that both paternal and maternal rejection are associated with GAD, but also that the relationship between GAD and parental rejection is stronger for maternal rejection. Some cultural factors may help to understand this. Namely, from a cultural perspective, mothers are entrusted with the task of caring for their children and tend to spend much more time with their children than fathers. Thus, it is possible that children and adolescents are exposed to more criticism and rejecting behavior in the maternal relationship, which could reinforce the association between maternal rejection and GAD compared to paternal rejection. However, there are other explanations. For example, it is possible that mothers, precisely because they are culturally primarily responsible for raising their children, are more likely to resort to disciplinary measures than fathers, which could reinforce adolescents’ perceptions of maternal rejection. In addition, mothers tend to be more at risk of parental burnout (Sorkkila and Aunola, 2020; Scigala et al., 2024) and in this situation it is possible that they are more likely to engage in negative parenting behaviors (Scigala et al., 2024), which could have a greater impact on adolescents’ perceptions of maternal rejection. It is therefore possible that children and adolescents are more intensely confronted with maternal rejection. This may shape the way in which the individual represents themselves and the relationship with others, fueling GAD symptoms. On the other hand, we should point out that the gendered, socially and culturally determined roles that bind mothers to childcare might nurture greater expectations of care, protection and affection from maternal figures than from paternal figures. In this sense, a negative relationship with the mother could reinforce the adolescents’ perception of maternal rejection. However, further research is needed to understand this finding.

Although our data show a stronger association between GAD symptoms and maternal rejection, we should not forget that our data indicate a strong association between GAD symptoms and paternal rejection in adolescents. This finding is important because it also attributes a possible role to the relationship with the father in the onset of GAD symptoms in adolescents. Indeed, the literature has largely ignored the role of the paternal relationship in the development or maintenance of anxiety symptoms in children and adolescents, attributing greater importance to the maternal figure (Bögels and Phares, 2008). This finding prompts us not only to further explore the unique contribution of the paternal figure in relation to GAD symptoms, but also to reflect on the paternal role in a cultural context such as the Italian one, where the maternal figure still tends to occupy the role of primary caregiver, suggesting a greater maternal responsibility in the processes of care, education and growth of children and adolescents.

Our study also shows a significant association between parental rejection (both maternal and paternal) and alexithymic symptoms. This finding is consistent with the literature that attributes an important role to the relationship with caregivers in shaping an individual’s emotional functioning (Cooke et al., 2019). The research data show that both adolescents (Lukas et al., 2022) and adults (Huang et al., 2022) with alexithymia tend to perceive the relationship with their parents as rather negative, characterized by low levels of affection and high levels of criticism and rejection. Parental rejection is seen as a form of emotional abuse that contrasts with the emotional needs for protection, affection and closeness that children express in the primary relationship with the caregiver. In such a relational context, the child is likely to develop an insecure attachment to the caregiver and lack a relationship that supports the child in developing appropriate emotional regulation skills. It is therefore possible that the child growing up in a similar relational context with the caregiver will increasingly use maladaptive emotion regulation strategies, such as suppression of emotions (van Strien et al., 2019). In this way, the child would have difficulty developing skills related to identifying and verbalizing their emotions, increasing the risk of developing alexithymic traits.

In addition, our study revealed the possible mediating role of alexithymia in the relationship between parental rejection and GAD. Specifically, the analyses showed that the three sub-dimensions of alexithymia, relating to “difficulty identifying feelings” (DIF), “difficulty describing feelings” (DDF), and “lack of subjective significance or importance of emotions” (LSS), were significant in mediating the relationship between maternal and paternal parental rejection and GAD, whereas the “externally-oriented thinking” (EOT) dimension was not significant. These data are in line with the research findings of Paniccia et al. (2018), who found in a sample of Italian adolescents that adolescents with GAD had higher scores specifically in the two sub-dimensions of alexithymia, namely “difficulty identifying feelings” (DIF) and “difficulty describing feelings” (DDF), compared to their peers without alexithymia. Similarly, in a comparison of adults with and without a GAD diagnosis, Marchesi et al. (2005) found no significant differences in the alexithymia sub-dimension of “externally-oriented thinking” (EOT), but found that the significant increase in alexithymia in GAD patients depended on the sub-dimension of “difficulty identifying feelings” (DIF). Overall, these data seem to suggest that it may be the affective components of alexithymia that play a role in the onset and maintenance of anxiety symptoms, particularly in GAD. Other evidence seems to point in the same direction. For example, Işıl (2023) recently found that the two sub-dimensions of alexithymia, “difficulty identifying feelings” (DIF) and “difficulty describing feelings” (DDF), are significant in mediating the relationship between remembered maternal rejection and somatic complaints in adults, whereas the subdimension “externally-oriented thinking” (EOT) is not (Işıl, 2023). In addition, our study identified the possible mediating role of the alexithymia subdimension “lack of subjective significance or importance of emotions” (LSS). There are no other studies that have examined this subdimension with which to compare our data, but an explanation could be offered. Indeed, individuals who have experienced a relationship with their parents characterized by rejection and criticism might be more prone to develop avoidant attachment, which is characterized by a marked tendency of the individual to deny their needs for emotional closeness, avoid emotional involvement and intimacy (Fabris et al., 2018). It is therefore likely that these individuals have learned to underestimate the importance of emotions and that this attitude helps them to reduce the occasions for emotional solicitation in interpersonal relationships. Individuals with avoidant attachment tend to use more emotion suppression strategies, and there is evidence that this is the most prevalent form of insecure attachment in the population of individuals diagnosed with GAD (Newman et al., 2016). However, further research is needed.

Overall, our data suggest that parental rejection (both maternal and paternal) is directly and indirectly through alexithymia, associated with the risk of GAD in early adolescents. In particular, our data seem to support the hypothesis that adolescents who experience a relationship with caregivers characterized by rejection and criticism tend to have a higher risk of reporting GAD symptoms, and that certain sub-dimensions of alexithymia (DIF, DDF, LSS) may partially explain this association. It is possible that parental rejection undermines the development of emotion regulation skills and causes the affected individual to resort more frequently to maladaptive emotion regulation strategies, such as emotional suppression, increasing the risk of developing alexithymic symptoms. In this sense, alexithymia, and in particular the difficulty in recognizing and verbalizing one’s own emotions, can make it difficult for the affected person to cope with and regulate negative and painful feelings. In order to avoid experiencing distressing negative emotions and the associated autonomic arousal, GAD individuals tend to use the abstract, verbal–linguistic process of worry (Cassidy et al., 2009). In practice, adolescents with GAD may attempt to defend or distance themselves from negative feelings by shifting their attention from negative emotions toward abstracted, conceptual thoughts (i.e., worry) (Mennin et al., 2002, 2005). Ultimately, worry can be seen as an extreme and maladaptive attempt to down-regulate anxiety triggered by uncertain, unpredictable or uncontrollable situations that trigger particularly strong negative emotions (Borkovec et al., 2004).

In summary, our study found that parental rejection is associated with increased symptoms of Generalized Anxiety Disorder (GAD) in early adolescents, with alexithymia as a potential mediator. Adolescents experiencing low affection and high rejection from parents are at greater risk of GAD due to difficulties in developing emotional skills, which hinders their ability to identify and verbalize emotions. This can lead to challenges in regulating negative emotional states, resulting in increased reliance on worry as a coping mechanism, further elevating the risk of GAD.
