Rejection sensitivity is one of the important constructs in social and clinical psychology that refers to a person's tendency to expect rejection, to quickly recognize possible signs of rejection, and to react strongly emotionally to situations that may be interpreted as inattention, criticism, or abandonment. This trait is especially important in childhood because children at this stage of development are forming their self-concept, self-esteem, sense of social belonging, and communication patterns, and their experiences in family, school, and peer groups can affect their perception of interpersonal relationships. Rejection sensitivity in children does not simply mean discomfort at not being accepted, but can also include a series of negative expectations, biased cognitive interpretations, emotional concerns, and behavioral reactions that are activated in social situations. A child with a high sensitivity to rejection may overestimate the likelihood of not being accepted when confronted with ambiguous behavior from others, interpreting cues such as classmates not responding, delaying receiving messages, not being selected for a game, or receiving corrective feedback from a teacher as a sign of their worthlessness or rejection. Such perceptions can increase feelings of insecurity, worry, sadness, and anger, affecting the quality of a child's social relationships. From a theoretical perspective, rejection sensitivity can be studied in the context of cognitive theories, social learning, attachment, and emotion regulation, as each of these approaches explains part of the process of forming social expectations and the child's reactions to the possibility of rejection. Based on the cognitive approach, the child's previous experiences and beliefs about his or her self-worth and the trustworthiness of others can influence his or her interpretation of social situations. If the child has faced repeated rejection, ridicule, harsh criticism, or emotional neglect in the past, he may gradually expect that new relationships will also be accompanied by rejection. In such a situation, the child will pay more attention to the cues that align with his or her negative expectation rather than unbiasedly evaluate the behavior of others. For example, if a friend is talking to another person during recess, they may assume that their friend is no longer willing to communicate with them. This perception can increase feelings of discomfort and lead the child to withdraw or defensive reactions, even if their friend's behavior has nothing to do with rejection. Repeating this process can lead to the formation of a negative cycle in which the expectation of rejection, negative interpretation of situations, intense emotional reaction, and maladaptive behaviors reinforce each other. One of the most important possible consequences of rejection sensitivity is an increase in interpersonal problems. Interpersonal relationships in childhood play an important role in developing communication skills, learning to collaborate, resolve conflict, and form a sense of belonging. Children who are constantly worried about being rejected may be cautious at the beginning of their relationship with others, need frequent affirmation to receive reassurance, or react strongly emotionally when faced with the slightest possible sign of inattention. These behaviors can affect the quality of social interactions and increase the likelihood of misunderstandings and conflicts. For example, a child who thinks that his classmates have ignored him may react angrily or decide not to talk to them anymore without investigating the reason for their behavior. In contrast, some children may overly give in to others' demands, refuse to express disagreement, or ignore their own personal needs to maintain friendships to avoid rejection. Both patterns can prevent the formation of balanced, mutually respectful relationships. In the first case, defensive and aggressive behaviors increase the likelihood of conflict, and in the second case, excessive dependence on the approval of others can undermine a child's sense of independence and social self-efficacy. Therefore, sensitivity to rejection may affect children's social relationships through different behavioral pathways. An important cognitive factor in this relationship is the negative interpretation of ambiguous social cues. Children's interpersonal situations are not always clear and predictable, and the behavior of others may have multiple causes. For example, a classmate's silence may be caused by fatigue, mental preoccupation, or personal concern, but a child sensitive to rejection may attribute it to apathy or hostility. This type of interpretation can increase feelings of social threat and prompt the child to react that would not be necessary under normal circumstances. As a result, a simple interaction that can be resolved peacefully may lead to conflict or distancing. If such experiences are repeated repeatedly, the child is likely to perceive social relationships as an unsafe environment and avoid communicating with others to prevent emotional harm. This avoidance can reduce the opportunity to learn communication skills and correct negative perceptions, exacerbating interpersonal problems in the long run. The relationship between rejection sensitivity and anxiety symptoms is also theoretical and clinically important. Children who are sensitive to rejection may anticipate potential negative consequences before entering social situations and have strong concerns about being accepted by peers or adults. This concern can manifest itself in situations such as answering a teacher's question, participating in a group activity, attending a birthday party, meeting new friends, or speaking in public. The child may repeatedly check in his or her mind what others will think of him, whether he or she will make a mistake, and whether his behavior will cause ridicule or dismissal. Such predictions can increase physiological arousal, muscle tension, heart palpitations, stomach pain, restlessness, or difficulty concentrating. In some children, worrying about negative evaluations may lead to avoidance of social situations, and in others, it may manifest itself in the form of a strong dependence on parental presence or repeated requests for reassurance. However, rejection sensitivity is not the same as anxiety disorder in itself, and is only one of the possible factors associated with experiencing social anxiety and other anxiety symptoms. To determine the clinical significance of these symptoms, the severity, persistence, proportionality of the child's developmental level, and the extent of impairment in the child's daily functioning must be assessed. From the perspective of attachment theory, the quality of a child's early relationships with primary caregivers can play a role in shaping his or her expectations about the availability of others and the stability of relationships. Children who experience predictable emotional response, acceptance, and support in their early relationships may feel more secure in the face of social uncertainty. In contrast, repeated experiences of rejection, neglect, or unpredictable reactions can be associated with increased anxiety about losing affection and acceptance in some children. However, the relationship between attachment and rejection sensitivity is complex, and a child's interpersonal problems or anxiety cannot be attributed solely to the quality of the initial relationships. Personality traits, subsequent experiences, relationships with peers, cultural circumstances, and environmental support also play a role in this process. Therefore, examining rejection sensitivity requires simultaneous attention to the child's history of emotional relationships and current life circumstances. Parenting style can also be important by influencing self-concept, sense of security, and the way others interpret their behavior. Frequent criticism, comparing the child to siblings or peers, humiliation, threatening to deprive the child of affection, and ignoring his or her emotional needs may undermine a sense of worth. In such a situation, the child may see acceptance of others as a prerequisite for his or her worthiness and become more sensitive to possible signs of disapproval in social relationships. In contrast, emotional support along with setting clear boundaries, encouraging independence, and accepting individual differences can help foster a sense of security and self-confidence. It is important to note that parental support should not become excessive protection of the child from all difficult situations, as such a pattern may limit the opportunity for independent experience, conflict resolution, and learning to tolerate failure. By providing age-appropriate opportunities for decision-making, communication, and conflict resolution, parents can help the child understand that every temporary disagreement or neglect does not mean the end of the relationship or the loss of social acceptance. Negative experiences in the peer group are also important factors associated with rejection sensitivity. Bullying, ridicule, exclusion from group games, gossip, and repeated rejection can reduce a child's sense of social security and affect their expectations of future relationships. Children who have repeatedly encountered disturbing behaviors may also quickly look for signs of danger in new situations and interpret the behaviors of others more cautiously. This reaction may initially be an attempt to protect oneself, but if generalized to all relationships, it can lead to social isolation and increased anxiety. On the other hand, a child's high sensitivity to rejection may alter the way they respond to peers and increase the likelihood of misunderstandings. Therefore, the relationship between rejection sensitivity and interpersonal problems can be two-way; negative social experiences reinforce sensitivity, and sensitivity may contribute to perpetuation of conflict or withdrawal in some situations. In the school setting, this may be associated with reduced class participation, difficulty in teamwork, fear of making mistakes, and dependence on teacher approval. A child who is afraid of criticism or correction of his or her performance may even perceive routine instructional feedback as a sign of personal dissatisfaction. Such a perception can shift his focus from learning to worry about the evaluation of others. Teachers can help reduce social insecurity by providing respectful feedback, clearly explaining expectations, and avoiding inappropriate humiliation or comparisons. Also, creating well-structured group collaboration opportunities and supporting children's gradual participation can provide the ground for learning communication skills. From an emotion regulation perspective, children who have difficulty identifying and managing emotions such as shame, fear, anger, and grief may react more strongly when faced with possible signs of rejection. For example, feelings of shame can lead a child to hide mistakes and avoid interaction, while anger may lead to a defensive or aggressive response. If a child is unable to recognize their emotion properly and think about the cause, they may see an immediate reaction as the only way to protect themselves. Teaching emotion regulation skills can help a child identify how they feel before reacting, review the available evidence, and choose a more appropriate response. Also, strengthening problem-solving and effective communication skills can reduce the likelihood of social misunderstandings turning into enduring conflicts. In this context, empathy training is also important, as understanding that other people's behavior may be influenced by different situations and emotions can prevent hasty interpretations. Research evidence in the field of developmental psychology and interpersonal relationships suggests that rejection sensitivity is associated with certain communication problems, concerns about social evaluation, and symptoms of internalizationare associated with anxiety and negative moods. However, the extent and type of this relationship may vary based on age, cultural background, previous experiences, and individual characteristics. Some rejection-sensitive children exhibit more avoidance behaviors, while others react in the form of emotional reactivity, extreme attempts to gain approval, or conflict with peers. These differences suggest that rejection sensitivity should not be considered the same pattern of behavior in all children. Also, observing the association between rejection sensitivity and anxiety alone does not prove a causal relationship, as both may be influenced by factors such as bullying experience, low self-esteem, emotional insecurity, or emotion regulation problems. Longitudinal research and multi-reference assessments can help clarify the chronological order of these relationships. One of the important applications of these findings is the early identification of children who have severe anxiety in social relationships or who repeatedly consider the behaviors of others as a sign of rejection. Evaluation should include dialogue with the child, examining the perspectives of parents and teachers, recognizing the history of peer relationships, and examining situations in which anxiety or conflict increases. The use of valid tools to measure rejection sensitivity and anxiety symptoms can help to better understand the child's situation along with the clinical interview, but the results of questionnaires should not be used as a basis for diagnosis alone. In terms of intervention, cognitive-behavioral approaches can help reduce rejection-related concerns by identifying negative interpretations, reviewing evidence, and practicing alternative perceptions. In this process, the child learns to distinguish between observable reality and his own subjective perception and to consider different possible explanations for the behavior of others. Practicing social skills, assertive dialogue, conflict resolution, and asking for help can also help increase interpersonal self-confidence. In cases where anxiety has caused significant avoidance, gradual and age-appropriate exposure to social situations, under the guidance of an expert, can provide the opportunity to experience success and correct negative predictions. The involvement of the family and the school in this process is important because the changes made in therapy sessions become more sustainable when the child's living environment also provides an opportunity to practice new skills. One of the important challenges in this area is the distinction between the sensitivity to rejection and the child's natural response to the actual experience of rejection or abuse. If the child is in an environment where he or she is genuinely subjected to ridicule, bullying, or repeated exclusion, simply teaching him or her to change his or her thoughts will not be enough, and the environmental conditions must be corrected. Ignoring the child's actual experience and attributing all of his or her concerns to subjective interpretations can increase feelings of distrust. Therefore, effective intervention should take into account both the child's cognitive perceptions and the true quality of his or her social relationships. Another limitation is the difficulty of accurately evaluating the internal experiences of young children, because some of them are unable to express their concerns and perceptions clearly. Cultural differences in the way emotions expressed, social expectations, and family relationships should also be considered in interpreting the results of the researches. In addition, rejection sensitivity may overlap with social anxiety, depressed mood, low self-esteem, and communication difficulties, so it is necessary to differentiate and pay attention to the general pattern of symptoms. In general, the relationship between rejection sensitivity with interpersonal problems and anxiety symptoms in children can be explained based on the interaction between cognitive expectations, social experiences, emotional reactions, and behavioral patterns. High sensitivity to rejection may cause the child to interpret ambiguous social cues negatively, avoid difficult interactions, or become more dependent on the approval of others to avoid rejection. These patterns can lead to a decrease in the quality of relationships, increased conflict, loneliness, and exacerbation of social concerns in some situations. However, the severity of these outcomes depends on individual characteristics, family circumstances, quality of peer relationships, and the level of environmental support, and the presence of rejection sensitivity alone does not imply a psychological disorder. Practically, increasing the awareness of parents and teachers, strengthening emotion regulation, teaching realistic interpretation of social situations, improving communication skills, and preventing bullying can help reduce the negative consequences of this trait. Finally, a holistic approach that examines both the child's subjective experience and the actual conditions of his or her social relationships can provide the ground for more accurate identification of risk factors, strengthening protective factors, and improving children's mental health and interpersonal adjustment.
