Studies have shown that important events in life can affect a person’s emotional performance, but some of these events do not necessarily have long-term destructive effects and vary between different people depending on the coping strategies employed. Studies have shown that patients with psychosomatic problems do not have adaptive coping strategies (
1). Gastrointestinal diseases, such as peptic ulcer, are examples of psychosomatic diseases that largely lead to referral to hospitals (
1). Peptic ulcer is referred to as mucosal lesions in the stomach, pylorus, duodenum, and esophagus. Peptic ulcer is a very common condition with a higher prevalence in men than in women (
2). The most common symptom of peptic ulcer is the burning pain that can be felt anywhere above the sternum. Weight loss, anorexia, and blood in stool are the other common symptoms of this disease (
3). Although this disease is not associated with a high mortality rate, it has many psychosocial, emotional, and economic consequences as it is highly prevalent (10 to 12%) (
4). Small ulcers are responsible for about 45% to 60% of hospitalizations due to acute gastrointestinal bleeding in the world (
5).
Preliminary studies on gastric ulcer have shown the role of psychological factors in the development of gastric ulcers (
6,
7). Psychological stress has been reported to induce gastric acid secretion (
8). Although stressful events have been considered major risk factors in bio-psychosocial research, many researchers believe that how people react to stressful events is more important than the stress itself (
9). Recent research has shown that the type of the coping strategies used by a person affect not only his/her mental health but also his/her physical well-being (
10). Coping strategies are the same behaviors and thoughts that are automatically used by people to deal with and minimize psychological damage. Stressful situations, if they are not managed properly, can cause psychological problems (
11). There are three types of coping strategies: (1) cognitive strategy, which involves evaluating the event as stressful (e.g., comparing it to past situations), (2) active-behavioral coping strategies, which include tasks used by people to assess stressful situations, which sometimes makes situations worse (such as smoking, rather than solving the problem), and (3) avoidance coping strategy, referring to avoiding facing a problem (i.e., escaping from it, for example, sleeping more hours and trying not to think about it (
12). Studies have shown that coping strategies are recognized as mediators between stress and illness (
13) and play an important role in reducing anxiety, depression, and physical problems (
14).
Peptic ulcers may develop in patients whose personalities and life experiences make them physically react to stressful stimuli. Some studies have identified active-behavioral and avoidance coping strategies as the most effective mediators of the disease-stress relationship (
15). Some other studies suggested that stress-related illnesses such as peptic ulcer were more common in those who constantly use active-behavioral and avoidance coping strategies (
16). On the other hand, employment of the cognitive coping strategy against stressful situations render events less stressful and soften reactions to its negative consequences (
16).
Figure 1 shows the relationship between coping strategies and stress in people with and without PUD, as mentioned in various studies (
17-
20).
Previous reports have often been focused on the role of biological agents, such as
Helicobacter pylori, and used a clinical approach and pharmaceutical treatment to manage PUD (
21). Meanwhile, the effect of socio-psychological variables on the occurrence and progression of peptic ulcers has not been investigated, especially in Iran. A few studies have examined the relationship between coping strategies in the face with stressful situations and PUD among Iranians (
17-
20), but most of these studies are correlational, and no interventional experiments have yet been done to assess the causative effects of these coping strategies. Therefore, this research investigated the efficacy of emotion regulation training on coping responses in attenuating the stress of life events in patients with PUD.
