Functional constipation (FC) is a common disease in children, defined based on Rome ΙV criteria as delayed or difficult defecation for two weeks or more without any organic cause (
1). About 3% of referrals to pediatricians and 25% of referrals to pediatric gastroenterologists are due to constipation (
2). The prevalence of FC has been reported to be higher in South Asia and South America compared to other regions in the world (
3). Among the factors predisposing vulnerable children to FC are urbanization, civil unrest, poor parenting skills, child maltreatment, and psychological distress (
3). The troublesome symptoms associated with this disease, such as abdominal pain, as well as rectal and anal pain, can significantly compromise the quality of life of these patients. In addition, fecal incontinence (known as soiling or fecal leakage to underwear) can be a major concern that decreases children’s self-confidence and exposes them to social isolation and punishment by parents, leading to more psychological harm to these children (
4). Overall, the chronic nature of constipation and unconstructive family performance can cause many behavioral problems, such as social isolation, low self-esteem, depression, aggression, anxiety, and, finally, decreased quality of life (

Anxiety disorders are among the most common disorders in children and adolescents, and social anxiety or social phobia is one of the most important of them (
8). This disorder is a complex neuro-psychological syndrome that has been recognized as an independent diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM5) (
9). Social anxiety disorder is a type of anxiety characterized by intense fear and anxiety in social situations caused by the fear of negative judgments by others. This highly debilitating type of anxiety interferes with many aspects of a person’s life. In young children, this type of anxiety may manifest itself as screaming, crying, or hugging relatives around them. On the other hand, older children and adolescents, when they face stressful social situations, experience panic-like symptoms. Individuals suffering from this disorder perceive social situations as annoying and try to avoid such situations as much as possible because they considerably hurt their professional, educational, and social functioning. In severe cases, social anxiety can considerably reduce the person's quality of life (
10,
11). According to epidemiological studies, this disorder, in most cases, initially appears in childhood and adolescence, underlining the importance of this period to prevent and manage this disorder (
12). The lifetime prevalence of this disorder in adolescents has been estimated between 10% and 15%, and girls have been reported to experience social anxiety disorder 1.2 to 2.1 times more than boys (
10,
13).
Different studies have noted the role of psychological factors in the development and persistence of FC. Depression, anxiety, and panic have been described to be related to constipation in several studies (
14-
16). Social anxiety is believed to be rooted in the child’s low self-confidence, and also, chronic FC is associated with decreased self-confidence in children due to its behavioral problems. Therefore, investigating the relationship between the two disorders can open new ideas in explaining the psychological consequences of FC. However, no study investigated the relationship between social anxiety disorder and constipation in children, reporting inconsistent results on the relationship between these two. This is while if such a relationship is confirmed, patients can benefit from appropriate psychological and nursing interventions, which can have an essential role in taking care of the children (
