One of the most important theoretical models related to anxiety and depression symptoms is Robert Leahy’s model of emotional schemas (
1). According to this model, individuals vary in how they experience and conceptualize emotions, and depending on their beliefs about emotions, they choose different ways to act. Individuals with many negative emotions tend to take extreme actions in relatively anxiety-provoking or undesirable situations. These individuals often blame themselves, are extremely self-critical, and show excessive sensitivity to others, which can induce emotional problems in the long run (
2).
Repetitive negative thoughts (RNTs) are associated with emotional disorders (
3-
5). Repetitive negative thoughts refer to “repetitive thinking about one or more negative topics that is experienced as difficult to control” (
6). Studies reveal that RNT levels are heightened in as many as 13 different disorders, including depression, PTSD, social phobia, and bipolar disorder (
6). Findings suggest that RNT serves as both a transdiagnostic correlate and a risk factor for the onset of mental disorders (
7). Worry and rumination, components of the RNT construct, are integral to the identification and development of symptoms associated with emotional disorders (

8,
9).
Anxiety sensitivity (AS), characterized by the fear of anxiety and its associated physical sensations, has garnered significant attention as a transdiagnostic construct in the developmental psychopathology and treatment of emotional disorders. Due to its multidimensional nature and the similar ways individuals respond to anxiety, numerous studies have examined its role in predicting and sustaining emotional disorders (
10). Studies have demonstrated that heightened AS is associated with increased severity of emotional disorder symptoms, as individuals misinterpret physical sensations as indicators of danger, leading to more intense anxiety symptoms (
11-
13).
Research indicates that a subgroup of two transdiagnostic factors, AS and cognitive flexibility (CF), is more strongly associated with coronaphobia (
14). Theoretical models of anxiety and depressive disorders frequently highlight CF and executive function processes as key factors in their development and maintenance (
15). Kashdan and Rottenberg identified CF as a fundamental component of psychological well-being and mental health (
16). Cognitive flexibility competence encompasses the development of cognitive processing strategies that enable individuals to adjust their responses according to situational demands (
17). Individuals with a high level of CF can effectively adjust to changing environmental demands by reorganizing their psychological resources, altering their perspectives, and managing competing desires, needs, and life domains (
16). Cognitive flexibility is characterized by an individual’s ability to remain present and self-aware, modify maladaptive behaviors, and engage in actions aligned with personal values. In recent years, it has been increasingly recognized as a framework for understanding psychopathology and mental health. Numerous studies have highlighted its role in alleviating anxiety, depression, and stress while promoting overall psychological well-being (
18,
19).
A study suggests that individuals with panic disorder and obsessive-compulsive disorder exhibit some similarities in metacognitive beliefs, emotional schemas, and CF (
20). After the announcement of COVID-19, people showed more negative emotions (anxiety, depression, and anger) and fewer positive emotions (happiness), leading to the creation of more negative emotions as a protective mechanism (
21). Therefore, psychiatric interventions are necessary during outbreaks of infectious diseases with high mortality rates (
22). Anxiety is a common psychological response in times of disaster (
23). Public health emergencies often lead to a variety of emotional-stress responses, including higher levels of anxiety and other negative emotions (
23). Understanding the potential psychological changes stemming from COVID-19 in a timely manner is necessary. Since mental changes arising from public health emergencies can be directly reflected in emotions and cognition, long-term negative emotions may impair individuals’ immune system function and compromise the balance of their natural physiological mechanisms (
21).
Among the factors associated with coping with and overcoming difficult and critical conditions, such as the COVID-19 crisis, are spirituality, seeking God, and seeking help from God (
24,
25). Attachment to God is defined as an individual’s relationship with and emotional orientation to God (
26). In this relationship model, God possesses many functions of attachment, such as being a safe haven in times of threat, to which believers resort to find the courage to face various life challenges. Although some studies have yielded contradictory results, they have shown a significant positive relationship between attachment to God and anxiety, indicating that greater attachment to God correlates with increased anxiety in performing daily tasks, leading to more anxiety symptoms (
27,
28).
Transdiagnostic approaches to psychiatric disorders propose the existence of shared underlying mechanisms that may function as predisposing or perpetuating factors (
20). Emotional disorders are among the most common psychological disorders humanity has faced to date. Therefore, the importance and necessity of research lie in identifying the factors influencing these disorders, which can lead to significant progress in controlling, preventing, or treating them. Given that emotional problems are not age-restricted and are prevalent in nearly all individuals, addressing the factors that influence them is of great importance.
Most studies in the field of transdiagnostic psychopathology of anxiety and depression have been conducted in normal populations, while this research explores these processes in clinical populations. Emotional schemas, AS, RNTs, CF, COVID-19 anxiety, and attachment to God have not been extensively studied in the Iranian population, and studies on the association of these processes are also surprisingly lacking. From a transcultural perspective, studies focusing on common processes for psychopathology in different cultures would aid in generalizing treatment recommendations for populations with diverse cultural backgrounds. Therefore, testing whether these proposed transdiagnostic processes are equally valid in the Iranian population might contribute significantly to the literature.
