Anxiety formation can be understood as the fulfillment of developmental tasks in this background in a way that is not appropriate for the development period. For example, the development of separation anxiety is facilitated if the autonomy development, which is the

An important discussion in developmental psychology is related to the development of emotions. Does the newborn bring with them feelings or do emotions vary later? Walters and Sroufe [2] argue that emotions will be varied during ontogenesis. The sense of fear develops through steps. It has a sense of not receiving pleasure and is closely related to the child's cognitive and social development. The first observed fear predecessors in the newborn are compulsory attention and insecurity. Fear is activated when there is a negative movement for the child. Izard and Sroufe acknowledge that the first fear appeared in the 7th month. The baby becomes restless if visual stimuli are given to the baby for 10–15 days. First, he reacts calmly and then becomes active, crying and shouting, because the child's activity ability was cut by the object. The content of the visual stimulus is not important here. Infants become restless as a result of a person looking at the baby's face for 30 s. Here, the baby acquainted with other foreign factors. The content of the warning has gained importance. 30 s after the response is the development

and the fear is varied and defines this period as mistrust.

**1.2. The risk factors of anxiety development**

From the 6th month, if a foreign person suddenly gets in the lap of the child, the babies react. This reaction is observed especially in all infants aged 10–12 months. Here, the foreign person is perceived as a kind of reverse event and creates a negative scheme in infants. This is the pioneer of fear/anxiety. As the age progresses, the content of the stimulus plays a greater role,

Fears are common in childhood. Their contents vary by age and are temporary. The cognitive development and developmental period of the child are in relation. For example, at the end of the first year, they fear foreign people, foreign places, and loud voices. At the age of 4, the fear

The most commonly used model in explaining the causes of psychiatric disorders is the diathesis-stress model [3]. Diathesis refers to the Greek predisposition and is considered to be the susceptibility of the individual to both structural and environmental factors and diseases and non-normative behaviors. The definition of an individual's response to any stress caused by the environment can also be extended. This individual predisposition may be determined as genetic, organic, biochemical, psychiatric, and/or social. The concept of diathesis was first used in schizophrenia research [4]. The other definition mentioned with diathesis is the concept of risk.

4 Anxiety Disorders - From Childhood to Adulthood

In family research, the incidence of the same disorder is screened in the relatives of people with psychiatric disorders. A number of family studies reported that panic disorder showed familial frequency [21, 22]. In recent years, the subject is frequently investigated and the relationship between the anxiety of children and the anxiety of parents [6, 7].

In the last family researches conducted by Cynthia Last, [8] 83% of the children diagnosed with separation anxiety were found to meet the anxiety disorder criteria at their mothers' lifetime.

About 57% meet the criteria of an anxiety disorder at the time of research. The second major study by Last [9]. Relatives of children with anxiety disorders, relatives of children with attention deficit hyperactivity disorder, and relatives of children without any psychiatric diagnosis were included in the study. Anxiety disorder was found in 40.4% of the parents of children with anxiety disorders. In the other two groups, anxiety disorder was quite low. The most common type of anxiety disorder among children with anxiety disorders is excessive anxiety (18.9%) and phobic disorder (11.7%). Panic disorder, social phobia, obsessive compulsive disorder, and avoidant personality disorders are more common in the relatives of children with anxiety disorders than in the control group.

Children with a diagnosis of anxiety disorder in their parents have a higher risk of developing anxiety disorder. Both axis studies indicate familial clustering in anxiety disorders. Evidence of more specific transitions, especially in panic disorder and social phobia, was obtained.

#### *1.2.2. Biological risk factors*

The effect of biological risk factors on the development of childhood and adolescent anxiety disorders was investigated in few studies. Studies on the subject were mostly conducted using adult subjects. In these studies, locus ceruleus, sympathetic system, and HPA axis were investigated. It has been shown that the levels of cortisol increases in the stress of normal children [10]. In studies with children with social anxiety, it was observed that heart rate increased compared to normal children. Kagan [11] found the low stimulus threshold with the participation of the amygdala and hypothalamus in the limbic system in children with anxiety.

Shaffer et al. [12] argued that some of the signals could be interpreted as an anxiety disorder precursor. The parents of children with agora phobia were found to be more frequent than the children who had motor-mild symptoms without the agoraphobia (Kaplan et al. [13]).

### *1.2.2.1. Increased startle reaction*

The startle reaction was observed for 6 months from the newborn period (Balaban [14]). In many studies, an increased startle reaction was found in individuals with anxiety disorder compared to the control group [23, 26]. Grillon found that parents with alcohol dependence showed an increased startle reaction to alcohol-dependent parents compared to their children. In the second study performed by the same study group, the startle reaction potentials of the parents of children with different anxiety disorders and the children of parents without a psychiatric disorder were compared. Higher startle potential was determined in girls. As a result, increased startle reaction may be considered as a predisposition factor in the development of anxiety disorder.

According to Kagan the children of individuals with panic disorder and agoraphobia showed more behavioral inhibition than healthy parents (Rosenbaum et al. [15, 16]). According to the results of two prospective studies, children with behavioral inhibition are in a high-risk group

As a result, in children with fixed behavioral inhibition in different time periods, more anxiety disorder can be diagnosed, and more behavioral inhibition is observed in the children of

In 1973, Bowlby [17] first mentioned the theory of attachment; in later years, Ainsworth [18]

Accordingly, in the first year of life, a special relationship behavior develops between the baby and the primary caregiver. As a result of standardized behavioral observations (foreign status test), three types of attachment style are mentioned: (1), secure; (2), ınsecure avoidant;

Parents of children who are securely connected can have empathy with the needs of the child

Depending on the attachment style, the child learns cognitions about interpersonal relationships and develops strategies for emotion control. The child creates an internal working model. What is present in this model is the person he trusts and the world. The child thus evaluates situations and regulates interpersonal relationships. This study model, if it occurs,

Chorpita and Barlow [19] developed a model of vulnerabilities related to the emergence of fear and depression. According to this model, early uncontrollable and predetermined stimuli result in poor control experience and increased neurobiological activity and consequently behavioral inhibition system introduced by Gray. Neurobiological activation leads to indeterminate somatic symptoms that have been described for the first time by Kagan [9]. This diminishing control experience is a risk factor in difficult life events in the future. Physiological effects as well as weakened control experience lead to chronic cognitive deviations and result in fear-anxiety phenomenon. This uncontrollability and prior uncertainty are experienced in

#### *1.2.3. Gender*

Childhood anxiety disorders constitute a risk factor for gender development in girls. Phobic disorder, anxiety disorder, and post-traumatic stress disorder are frequently seen. On the other hand, childhood obsessive compositional disorder is more common in boys. Separation anxiety disorders are seen equally in both sexes [25]. Biological and psychosocial study hypotheses were used to explain gender differences in anxiety disorders. The effects of sex hormones on monthly onset, menopause, pregnancy, and postpartum period anxiety symptoms in biological theories were investigated. In general, these explanations are not sufficient to explain the gender differences that we have found in childhood. Genetic factors are discussed as the cause of anxiety disorders in girls. For example, according to Drowe et al. (1983), the panic disorder is genetically inherited, and the genes responsible for panic disorders in women show a high transition. According to [24], genetic factors play an important role rather than gender-aware environmental factors. At present, it is unclear which gene causes gender difference in anxiety disorders.
