Migraine is the second neurological disorder with deep pain that causes a wide range of problems for the affected people and those around them. Therefore, the purpose of this study was to model the causality of pain perception in migraine sufferers based on distress intolerance with the mediating role of fear of disease progression.

The current research is descriptive and the statistical population included all people with migraine who referred to clinics and neurologists' offices in Mashhad in 2022; out of which, 200 applicants were selected as a sample using the convevience sampling method. And they responded to Simons and Gaher's Emotional Distress Tolerance, Melzack's Pain Perception, and Herschbach et al.’s Fear of Disease Progression Questionnaires. To analyze the data, structural equation modeling was used.

A positive and significant relationship was observed between pain perception score and fear of disease progression score (r=0.470, p<0.01), and a negative and significant relationship was observed between pain perception score and distress tolerance score (r=-0.425, p<0.01). Furthermore, emotional distress tolerance had indirect association with pain perception through affecting the fear of disease progression.

The findings showed that the fear of disease progression plays a mediating role between the intolerance of distress and the perception of pain in migraine sufferers. Considering the association of pain perception and intolerance of distress and fear of disease progression in migraine, psychologists and specialists can use the improvement of these factors to increase the effectiveness of other methods for migraine treatment.

Chronic diseases challenge the cognitive and behavioral systems of patients. The purpose of the present study was to compare the effectiveness of group training of coping skills and mindfulness on pain perception and cognitive flexibility in patients with kidney failure with a lasting effect.

This semi-experimental study was carried out cross-sectionally. The statistical population of this study included all kidney failure patients who were referred to Shariati Hospital in 2021-2022 (from February to June). Accordingly, 45 patients with kidney failure were selected voluntarily and were randomly assigned to two experimental groups and one control group by using matching method. All the three groups responded to the McGill Pain Questionnaire (1997) and the Cognitive Flexibility Questionnaire (2010) in the pre-test, post-test and follow-up stages. The group therapy program based on mindfulness on the first experimental group and coping skills on the second experimental group were implemented in eight sessions, each lasting for one hour and a half.

The findings indicated that group training of coping skills and mindfulness leads to a reduction in pain perception and an increase in cognitive flexibility. Therefore; There is no significant difference between the effectiveness of group training of coping skills and mindfulness on pain perception and cognitive flexibility in patients with kidney failure (P = 0.001).

Two types of grouping training interventions, coping skills and mindfulness; can affect pain perception and cognitive flexibility in patients with kidney failure, and this effectiveness continue

MS is one of the most common chronic diseases of the central nervous system. This disease causes many mental disorders in patients. The purpose of this study was to investigate the effectiveness of acceptance and commitment therapy on life expectancy and pain perception in patients with MS in Mashhad.

This was a semi-experimental study with a pre-test, post-test and control group design. The statistical population included all patients with MS in Hazrat Qaim (AS) hospital in Mashhad in 2022, from among whom 30 people were selected by available sampling method and randomly placed in two experimental and control groups, 15 people in each group. became The experimental group received 8 60-minute sessions of acceptance and commitment therapy, and the control group was placed on the waiting list. The research tool was Miller's Life Expectancy Questionnaire and McGill's Pain Perception Questionnaire. Research data were analyzed by multivariate covariance analysis and using SPSS version 21 software.

The findings showed that acceptance and commitment therapy is effective on life expectancy and pain perception in patients with MS in Mashhad (P<0.05).

Treatment based on acceptance and commitment can be a suitable treatment for improving the psychological factors of life expectancy and pain perception of patients with MS.

Sport, especially at the professional level, is associated with a high risk of injury. One of the high-risk sports is Taekwondo, which according to the World Taekwondo Federation (2020) is one of the most popular sports with 75 to 120 million practitioners in more than 174 countries. Like other martial sports, there is a lot of potential for injury in Taekwondo along with sports performance; In such a way, the surveys conducted in taekwondo competitions show that the total injury rate is 139-5/20 per 1000 competitions for men and 105-5-3/25 for women. Anterior cruciate ligament injury is one of the injuries that taekwondo athletes face. As a static and dynamic structure, the cruciate ligament plays an important role in the stability of the knee joint, and it is a very important injury in the knee joint that affects the physical and mental health of athletes. It occurs after an air strike. There are increasing changes in subjective outcomes following sports-related cruciate ligament treatment and surgery, so that psychological factors also play a role in post-treatment outcomes and affect how athletes perceive pain, as well as their willingness to return to their previous level of activity and participation. They affect rehabilitation. One of the psychological dimensions and related skills that are of interest to psychologists and sports officials and experts; Pain perception is related to people's sports performance and can play an important role in the athlete's decision not to return to sports, especially after procedures such as cruciate ligament reconstruction. Athletes may exhibit "pain catastrophizing," a tendency to exaggerate pain and ruminate on the pain experience. In fact, the perception of pain changes the mental and social performance of the athlete and can be considered as an important factor limiting the physical and mental health of the injured athlete. Subjective interpretation of injury-induced pain is influenced by injury history in athletes; As long as the person's assessment of the pain experience caused by the injury does not change, the person will remain in this vicious cycle, leading to fear of movement or fear of re-injury; In such a way that in this case, the person is very worried about possible injuries caused by physical activities. Sports injuries are associated with negative psychological responses; Psychological factors play a role in post-treatment outcomes and affect how athletes perceive pain as well as their willingness to return to their previous activity level and participate in rehabilitation. Therefore, the aim of the present study was the effectiveness of psychological skills training on mental strength and self-confidence in taekwondo athletes with anterior cruciate ligament injury.

The present study was a pre-test-post-test experiment with a control group in terms of its practical purpose and design. The statistical population included all male taekwondo athletes with cruciate ligament injury in Tehran in 1402. First, a list of taekwondo clubs in different areas of Tehran city was prepared and then 30 people were selected from among the athletes with cruciate ligament injuries using a random sampling method and completely randomly divided into two experimental groups (15 people) and the control group. (15 people) were replaced. Then, the experimental group was invited to participate in the psychological skills training course, and after the introduction, confidence building and description of the intended goals; It was explained to the athletes that this intervention is a part of a research activity and that the matters raised in the meetings and their identity information will not be included and discussed anywhere without their consent and will not be given to any unit. Next, the McGill Pain Perception Questionnaire (MPQ) was given to both groups as a pre-test. Then, the experimental group was trained in the psychological training program for 16 sessions (2 sessions per week and each session for 45 minutes). The control group did not receive any training. The data was analyzed based on univariate analysis of covariance (ANCOVA) by SPSS-26 software.

The result of covariance analysis test showed that the sum of squares of the independent variable is 102.612, which leads to the F test size of 74.717, which is reported to be significant at the 0.01 level. In other words, there is a significant difference between the two control and experimental groups in the amount of pain perception after adjusting the effect of the pre-test. According to the average scores of the experimental and control groups in the post-test, it can be concluded that the practice of psychological skills has an effect on the pain perception of taekwondo athletes with anterior cruciate ligament injury. The effectiveness rate was also reported as 0.79.

In explaining this finding, it can be said that the perception of pain changes the mental and social functioning of the athlete and can be considered an important factor limiting the physical and psychological health of the injured athlete. The perceptual evaluation of pain is more complicated than other sensory thresholds due to its subjective nature. Subjective interpretation of injury-induced pain is influenced by injury history in athletes. As long as the person's evaluation of the pain experienced from the injury does not change, the person will remain in this vicious cycle, leading to fear of movement or fear of re-injury. In such a way, in this case, the person is very worried about possible injuries caused by physical activities. It seems that psychological skills in the field of voluntary skills (to overcome pain and fatigue due to specific performance needs) leave a positive and significant performance. In fact, injured athletes use psychological interventions to increase satisfaction in the rehabilitation process, improve treatment time, and return to the original physical state after surgery, as well as prevent further injuries, manage pain, and improve the level of rehabilitation. Conscious and purposeful intervention is therefore a critical criterion for volitional regulation processes. By focusing on performance-related processes, performance is actively aligned and the distraction of performance barriers is reduced. Self-talk, visualization, and relaxation techniques in the field of psychological skills were used separately or in combination to control the focus on relevant processes during sports activity. The ability to manage pain with psychological processes has been considered since the 1970s and is considered a threat to the physical integrity of a person It is associated with increased arousal and anxiety, which makes it even more uncomfortable. The body stiffens, which makes physical effort even less effective and more painful. However, what athletes experience during training and competition can be considered discomfort and not pain. They can always control the pain by reducing or stopping physical activity. Athletes have a higher perception of their pain when playing due to their motor skills, sports history and higher self-confidence; The opiate-like systems in their frontal cortex are less active and as a result, their sensitivity to pain has decreased. In general, it can be said that the practice of psychological skills has an increasing effect on the perception of pain in taekwondo athletes with anterior cruciate ligament injury.

Neuropathic pain is a large and difficult group of peripheral nerve diseases, which are complicated to treat. This study was designed to determine the effectiveness of acceptance and commitment therapy (ACT) on psychological well-being and pain perception among patients with chronic neuropathic pain.

This clinical trial was performed on 30 patients with chronic neuropathic pain who were referred to the Rohani Hospital and private clinic of a neurologist in Babol (Iran) in 2022. The patients were randomly divided into an interventional and a control group. The patients completed the psychological well-being scale (Ryff) and pain belief and perception inventory (Williams and Thorn) in the pretest. Then, ACT (120 minutes) was performed for the interventional group, 8 sessions a week. The patients completed the scales after the treatment course and 2 months after the posttest.

In the first follow-up, there were significant differences between the two groups in terms of total score of psychological well-being (P<0.05), the subscales of self-acceptance (P<0.05), positive relationships with others (P<0.05), autonomy (P<0.05), environmental mastery (P<0.05), purpose in life (P<0.05), personal growth (P<0.05), the total score of pain perception (P<0.05), the subscales of belief in the stability of pain in the present (P<0.05) and belief in the mysteriousness of pain (P<0.05). The treatment results were maintained in the second follow-up phase. In the first follow-up, the subscales of belief in the continuation of pain in the future and belief in self-blame did not differ significantly between the two groups, but in the second follow-up, the subscales of belief in the continuation of pain in the future (P<0.05) and belief in self–blame (P<0.05) differed significantly between the two groups. In addition, the average psychological well-being in the intervention group was higher than that in the control group, and the average pain perception in the intervention group was lower than that in the control group.

This study shows the ACT could be an effective intervention for improving psychological well-being and pain perception among patients with chronic neuropathic pain.

Integrative transdiagnostic and dialectical behavioral therapy seem to affect the hope and pain perception of cancer patients. The aim of this study was to compare the effectiveness of integrated transdiagnostic therapy and dialectical behavioral therapy on hope and pain perception of cancer patients in Isfahan.

The method of this study was quasi-experimental with a control group. The statistical population of the study was all cancer patients in Isfahan in 1400. Of statistical population, 63 patients were selected by available sampling and randomly assigned to two experimental groups and one control group. The experimental groups were trained with specialized protocols. Data were analyzed by repeated measures analysis of variance and Bonferroni post hoc test. 

Compared to the control group, integrated transdiagnostic and dialectical behavioral therapy resulted in improved hope and pain perception of cancer patients in the post-test (P<0.001), and these results also showed a lasting effect in the follow-up phase. The effect of integrated transdiagnostic and dialectical behavioral therapy on hope and pain perception of patients with cancer was not different in post-test and follow-up stages.

Integrative transdiagnostic and dialectical behavioral therapy are likely to improve hope and pain perception in cancer patients.

 Safe and satisfactory delivery with the least pain experience is one of the important principles in providing midwifery services in any society and culture. The key point in the management of labor pain is the ethical commitment of the service providers. Therefore, this study was conducted with the aim of comparing the relationship between the observance of medical ethics on the part of the medical team during the delivery process and labor pain perception in the women having natural births from the perspective of the parturient women visiting the birthing centers in Yasuj and Shiraz.

 This research is a correlational descriptive study. The study population consisted of 400 parturient women visiting the maternity hospitals affiliated to Yasuj and Shiraz University of Medical Sciences in 2019. Sampling was done through convenience sampling method. The data collection tools included a demographic information questionnaire, the Perception of Labor Pain Questionnaire (PLPQ) by Yadollahi etal and Medical Ethics Attitude in Vaginal Delivery Questionnaire (MEAVDQ) by Mirzaee et al. The data were analyzed through SPSS 22 software using Pearson's correlation coefficient and regression analysis. The significance level was p<0.05.

Ethical Considerations:

 Ethical considerations were observed through completing the informed consent form, voluntary participation and explaining the research objectives.

 According to the parturient women in the city of Yasuj (group 1), respect for autonomy (β=-0.530, P=0.001) as well as the principles of beneficence and non-maleficence (β=-0.361, P=0.002) were the negative predictors of the score of labor pain perception. However, according to the women in Shiraz (group 2), only the principles of beneficence and non-maleficence (β=-0.267, P<0.037) were the negative predictors of the score of labor pain perception. In addition, observing the principle of respect for autonomy was different from the viewpoints of the parturient women in the two groups (P=0.006)

 Considering that the second and the third principles of medical ethics, beneficence and non-maleficence, are of equal importance in both cultures, the delivery team can reduce the severity of labor pain through paying complete attention to both the mother and the fetus, as well as avoiding unnecessary intervention in any culture. Therefore, it is possible to take a step towards promoting maternal and child health and prevent further irreparable psychological harm to mothers.

To present a structural model of pain perception based on childhood trauma, early maladaptive schemas mediated by emotion regulation in people with chronic pain.

The research method was descriptive of correlation and structural equations. It was in 1399 that 300 of them (175 females and 125 males) were selected by available sampling method. They responded to the Granfsky and Craig (2006) Emotional Cognitive Regulation Questionnaires, Young's Early maladaptive Schemas (1991), and the Visual Animal Scale. The data were analyzed using structural equation analysis and hierarchical regression analysis. Showed that both positive emotion regulation strategies and negative emotion regulation strategies play a mediating role in the relationship between pain perception and early maladaptive schemas in patients with chronic pain. 

The tendency of individuals to use positive or negative leaders of emotional cognitive regulation can be a determining factor in the effect ofchildhood trauma, maladaptive schemas on the perception of chronic pain.

Research evidence confirms physiological and psychological differences in men and women with substance abuse. In this regard, in the present study with the aim of examining gender differences in the treatment of drug abuse, in the psychological dimension, pain perception, resilience, failure tolerance and aggression of women and men who have been treated who compared with methadone maintenance program.

In a descriptive study with causal-comparative method among people referring to addiction treatment centers in Tehran, Iran in the fall and winter of 2019 who were in-treatment with methadone, 300 people (150 men and 150 women) with an age range of 17 Up to 36 years and high school diploma or higher education were selected by multi-stage random cluster sampling method and answered the questionnaires of pain perception with (0.87 reliability), resilience (0.84 reliability), failure tolerance (0.72 reliability) and aggression (0.71 reliability). The obtained data were analyzed using Paired-Sample T-Test by SPSS software version 24.

The highest frequency was related to people between 22 and 26 years old with bachelor's degree and 11 to 15 years of work experience. Variables’ means in women and men were respectively 4.152±0.521 and 3.258±0.359 for pain perception, 3.961±0.357 and 3.651±0.198 for resilience, 4.208±0.303 and 3.247±0.137 for failure tolerance and 3.621±0.211 and 4.188±0.652 for aggression. The difference between men and women in pain perception, failure tolerance and aggression was significantly observed. However, there was no significant difference between men and women in resilience.

Women experience more pain and less failure in the process of quitting drugs with methadone than men, but men show more aggression than women. The process of quitting methadone seems to be more difficult for women than men. The resilience of men and women in this treatment program have no differences.

The process of cancer and its treatment has effects on patients, so that the physical and mental function of the patient is reduced. In this regard, the use of therapeutic approaches to improve mental health problems caused by the disease has been identified and presented. Considering the repetition of other therapeutic strategies and the variety of psychological problems of patients with cancer, lack of use of two strategies of integrated transdiagnostic treatment and dialectical behavior therapy (DBT) in the group of patients with cancer, and the impact of a person's cognitive skill on maintaining mental health, the purpose of the present study was to compare the effectiveness of integrated transdiagnostic treatment and DBT in psychological well-being and pain perception of patients with cancer

The design of this quasi-experimental study was pre-test, post-test, and follow-up with a control group. The statistical population of the study consisted of all patients with cancer in Isfahan, Iran, in 2021. The study sample consisted of 63 patients with cancer who were selected by the available sampling method and randomly assigned to three experimental and control groups. Research data were collected using McGill Pain Questionnaire (MPQ) and Ryff's Psychological Well-Being Scale and analyzed using repeated-measures analysis of variance (ANOVA) in SPSS software.

Integrated transdiagnostic and DBT education was effective in improving pain perception and psychological well-being of patients with cancer in the experimental group compared to the control group. Moreover, there was a significant difference between the two educational strategies (integrated transdiagnostic and DBT) in the post-test for variable of pain perception (P = 0.58 and P = 0.42, respectively) and for the psychological well-being variable (0.27 and 0.17, respectively). In the follow-up phase, it was obtained as 0.58 and 0.43 for the pain perception variable and 0.30 and 0.17 for the psychological well-being variable (P < 0.01). Integrated transdiagnostic treatment has been more effective in the psychological well-being and pain perception of patients with cancer.

Integrated transdiagnostic treatment and DBT lead to increased psychological well-being and improved pain perception in patients, and health professionals can use this treatment method to improve the psychological performance of patients.
