Chronic pain results from a complex interaction of biological, psychological and social factors that causes the experience of pain. The purpose of this research was to identify the structural model of chronic pain based on mindfulness, social support and life events with the mediating role of psychological distress and pain catastrophizing.

This was a descriptive-correlational study with structural equation modeling. The study population included all patients suffering from chronic pain with musculoskeletal and rheumatoid arthritis related pain, which had referred to Tehran medical centers for follow-up in 2023. A total of 496 people were selected using the convenience sampling method. They completed the McGill Pain Questionnaire (1957), the Bauer Five Factor Mindfulness Questionnaire (2006), the Perceived Social Support of Zimmet et al. (1988), the Pickel's Stressful Life Events (1971), the Leviband's Depression, Anxiety and Stress Questionnaire (1995) and the Pain Catastrophizing Scale of Sullivan et al. (1995). Research data were analyzed using SPSS-26 and AMOS-23 softwares using Pearson correlation coefficient and structural equation modeling.

The results of the structural equation model indicated that this model fits the experimental data well. The direct effects of the standard pathway mindfulness coefficient and the amount of stressors on chronic pain were significant (p<0.01) and the direct effects of social support and the number of stressors for chronic pain was insignificant. Additionally, the effects of standard indirect path coefficients for mindfulness, social support and the number and the amount of stressors with the mediating role of psychological distress and pain catastrophizing on chronic pain was significant (p<0.01).

Mindfulness, social support and life events play an important role in explaining chronic pain through the mediation of psychological distress and pain catastrophizing. Therefore, the findings of this study can be used in more detailed planning of psychotherpeutic interventions for patients with chronic pain.

 The present study was conducted with the aim of determining the effectiveness of acceptance and commitment therapy on pain catastrophizing and life satisfaction in women with chronic pain.

This study was semi-experimental with a pretest-posttest and follow-up with a control group design. The statistical population was made up of female patients with chronic pain referred to Emma Reza hospital in Tabriz city in 2023. In total, 30 people were selected by purposive sampling method, and randomly divided into two groups (15 people each). Members of the experimental group received their treatment in eight sessions of 1.5 hours; however, the control group did not receive any treatment. Both groups answered the 29-question Sullivan et al pain catastrophic and 48-question Diener et al life satisfaction Questionnaires, before, after and 3 months after the intervention. Data were Analyzed using ANOVA with repeated measures.

There was no significant difference between the scores of pain catastrophizing and life satisfaction in the experimental and control groups in the pre-test (P<0.05). The results showed that acceptance and commitment therapy reduced and increased pain catastrophizing and life satisfaction of women with chronic pain in the post-test, compared to the control group, respectively (P<0.001). The effect of acceptance and commitment therapy on pain catastrophizing and life satisfaction was lasting in the follow-up phase (P<0.001).

It seems that acceptance and commitment therapy can reduce pain catastrophizing and increase life satisfaction in women with chronic pain, therefore it is likely to be a useful treatment strategy to improve the pain catastrophizing and life satisfaction in women with chronic pain.

The aim of this study was to determine the effectiveness of acceptance and commitment therapy (ACT) on the aggression and pain catastrophizing in girls with premenstrual dysphoric syndrome.

This study was semi-experimental with a pretest-posttest and follow-up with a control group design. The statistical population was made up of female high school students suffering from premenstrual dysphoric symptoms in Tabriz city in 2023. In total, 30 people were selected by purposive sampling method, and randomly divided into two groups (15 people each). Members of the experimental group received their treatment in eight sessions of 1.5 hours; however, the control group did not receive any treatment. Both groups answered the 29-question Bass and Perry aggression and 13-question Sullivan et al pain catastrophizing  questionnaires before, after and 4 months after the intervention. Data were Analyzed using ANOVA with repeated measures.

In the pre-test, the mean and standard deviation of ACT for aggression were 57.60±5.00 and for pain catastrophizing 37.13±4.79, and in the control group for aggression were 57.93±6.59 and for pain catastrophizing it was 38.40±5.27 (P<0.05). ACT reduced aggression (43.93±5.99) and pain catastrophizing (32.93±5.16) in girls with premenstrual dysphoric syndrome in the post-test (p<0.001). In the follow-up phase, the effect of this treatment for aggression (44.07±5.86) and pain catastrophizing (33.07±5.14) was lasting  (p<0.001).

According to the results of the present study, it can be said that the acceptance and commitment therapy can probably reduce the aggression and pain catastrophizing in girls with premenstrual dysphoric syndrome.

Multiple sclerosis (MS) is a progressive chronic disease that can have an effective role on the psychological status of these people due to physical disability and chronic pain. Considering the importance of this issue, the present study was conducted with the aim of investigating the effectiveness of compassion-focused acceptance and commitment therapy on catastrophizing and acceptance of pain in people with MS.

The statistical population of the present clinical-trial study included all MS patients of Borujerd, Iran, registered in the MS Association in 2022. Fifty participants voluntarily participated in the present research and were randomly divided into two groups; 25 people in each group. Treatment group sessions based on acceptance and commitment with a focus on compassion included 10 90-minute sessions that were held once a week for the intervention group; but the control group did not receive any intervention during this period. In the present study, Pain Catastrophizing Scale (PCS) and Chronic Pain Acceptance Questionnaire – Revised (CPAQ-R) were used. Data analysis was done in SPSS-24 statistical software using repeated measurement variance analysis.

The results indicated that the intervention was significant over time on the variables of pain catastrophizing (F=5.347, p=0.007) and pain acceptance (F=30.446, p=0.001). In fact, the results of the Bonferroni test displayed that in the treatment group, there were changes between pre-test and post-test (p=0.001) and pre-test and follow-up (p=0.001) in the variables of pain catastrophizing and acceptance. There was a significant difference in pain, but no significant difference was observed between the post-test and the follow-up, which indicated the stability of the treatment effect over time. No significant difference was observed in the control group.

In general, it can be concluded that acceptance and commitment therapy with a focus on compassion had an effective role in reducing pain catastrophizing and increasing pain acceptance in MS patients.

The present study was conducted with the aim of investigating the effectiveness of cognitive analytic therapy on anxiety sensitivity and pain catastrophizing in patients with chronic pain and alexithymia.

This was a semi-experimental research with pre-test, post-test ,a two months' follow-up, and a control group. The statistical population included all the patients with chronic pain in Isfahan city in 2022. Sampling was done through convenience sampling method among the volunteer patients referred to private clinics in two stages. 24 patients with chronic pain who scored above 60 in Toronto alexithymia questionnaire (1994) were selected and were randomly assigned to experimental and control groups (n = 12). The instruments included  Sullivan's pain catastrophizing scale questionnaire (1995) and Taylor and Cox's anxiety sensitivity questionnaire (1998. The experimental group received cognitive analytical therapy for 16 90-minute sessions once a week, and the control group did not receive any intervention. Data were analyzed using repeated measure and ANOVA analysis.

The results of data analysis showed that there was a significant difference between the adjusted mean of anxiety sensitivity and pain catastrophizing in the two groups. The mean scores of anxiety sensitivity and pain catastrophizing variables increased in post-test and follow-up phase (P<0/05). Therefore, it can be concluded that cognitive analytic therapy was effective for anxiety sensitivity and catastrophizing pain in patients with chronic pain and alexithymia (P<0/05).

Considering the effect of cognitive analytic therapy on anxiety sensitivity and pain catastrophizing, this treatment method can be used to improve patients with chronic pain and alexithymia.

Premenstrual dysphoric disorder (PMDD) and pain catastrophizing significantly affect the quality of life in adolescent girls. This study aimed at investigating the effectiveness of acceptance and commitment therapy in reducing symptoms of PMDD and pain catastrophizing in this population.

This quasi-experimental study utilized a pre-test, post-test, and follow-up design with a control group. The study population consisted of female high school students with PMDD in Tabriz, Iran, in 2022. Thirty girls were purposefully selected and randomly assigned to either the experimental or control group (15 girls each). The experimental group received eight 1.5-hour therapy sessions, while the control group did not receive any intervention. Both groups completed questionnaires comprising 19 items on PMDD and 13 items on pain catastrophizing before the intervention, immediately after, and three months later.

The mean age of the experimental group was 16.80±0.77 years, and the control group was 16.53±0.64 years. In the pre-test, the mean score for acceptance and commitment therapy for PMDD was 57.60±5.00 and for pain catastrophizing was 37.13±4.79 in the experimental group, while in the control group, they were 57.93±6.59 and 38.40±5.27, respectively (P<0.05). Acceptance and commitment therapy significantly reduced symptoms of PMDD (43.93±5.99) and pain catastrophizing (32.93±5.16) in the post-test (P<0.001). The effects of therapy on PMDD (44.07±5.86) and pain catastrophizing (33.07±5.14) remained significant in the follow-up phase (P<0.001).

Acceptance and commitment therapy shows promise in reducing symptoms of PMDD and pain catastrophizing in adolescent girls, suggesting its potential as an effective intervention for improving their quality of life.

 The purpose of this study was to compare the effectiveness of logotherapy (LT) with acceptance & commitment therapy (ACT) on pain catastrophizing and sense of mental coherence in women with breast surgery experience.

This was a semi-experimental study with a pretest-posttest, controlled design with follow-up. The study population consisted of all women with breast cancer who were undergoing postmastectomy radiotherapy in Tabriz in 2023. In total, 45 women were selected by a purposive sampling method, and divided into three groups, 10 each. The ntervention groups received their respective treatments over 8 sessions of 1.5 hours. The control group did not receive any intervention. Members in three groups responded to the 13-item pain catastrophic of Sullivan et al and 35-item Flensberg Sense of Coherence Questionnaires, after and 4 months after the intervention. Data were analyzed with repeated-measures analysis of variance.

The results showed that LT (30.1±5.3) and ACT (29.9±5.4) in comparison with the control group (37.6±5.2), in the post-test, reduced the pain catastrophizing of women with breast surgery experience (P<0.001), and these results also show a lasting effect in the follow-up stage (P<0.001). Also, the results showed that LT (55.2±3.5) and ACT (55.0±2.9) compared to the control group (48.8±3.5), in the post-test, increased the sense of mental coherence of women with breast surgery experience (P<0.001), and these results also show a lasting effect in the follow-up stage (P<0.001). The results also showed that the effect of these two treatments on pain catastrophizing and sense of mental coherence in the post-test and follow-up stages were not different (P>0.05).

Logotherapy and acceptance & commitment therapy  reduces the pain catastrophizing and increases the sense of mental coherence in women with breast surgery experience.

Chronic pain is one of the most common problems that prompt people to seek medical care and is associated with numerous health, economic and social consequences. This research was conducted with the aim of determining the effectiveness of spiritual therapy on pain catastrophizing and self-control in patients with idiopathic pain.

The present study was a semi-experimental study with a pre-test and post-test design with a control group and a six-month follow-up period. The statistical population of the research included all the patients with muscle pain who referred to pain clinics in Tehran in 2022-203, 30 people were selected by the purposeful sampling method and randomly assigned to two equal groups of 15 people. Data collection was done with the PCS by Sullivan et al, and SCQ by Tangney et al. Spiritual therapy was implemented during 8 sessions, two sessions a week and each session lasted for 1 hour for the subjects of the experimental group, but the subjects of the control group did not receive these programs. Data analysis was done with descriptive statistics and variance with repeated measurements using SPSS-26 statistical software.

The average score of pain catastrophizing and its dimensions (mental rumination, magnification, helplessness) in the experimental group significantly improved after the intervention compared to the control group (P<0.05). Spirituality therapy was beneficial on increasing self-control and its dimensions in the subjects of the experimental group, unlike the control group (P<0.05). The effects of this program on dependent variables continued during the six-month follow-up period (P<0.05).

These findings further clarify the role of mental and behavioral structures in chronic pain sufferers and reveal the necessity of using therapeutic approaches derived from spirituality in order to adjust the symptoms of patients with chronic pain.

To investigate the structural relationships between chronic pain and body mass index mediated by eating behaviors, pain-related fear, anxiety sensitivity, and pain catastrophizing.

The research method was structural equation modeling and the statistical population of men and women with chronic pain referred to the orthopedic, physiotherapy, neurology wards of Al-Ghadir Hospital and orthopedic specialists of Farahbakhsh clinics in Tehran in spring, summer and autumn of 2022, of which 400 they were selected by purposive sampling method and participated in the research. Data were used to calculate participants' body mass index and the Dutch Eating Behavior Questionnaire (Van Strien, Frijters, Bergers & Defares, 1986), Chronic Pain (Vankorff et al, 1990), Pain Anxiety Symptom Scale (Pain-Related Fear) (McCracken & Dhingra, 2002), Anxiety Sensitivity Questionnaire (Patterson and Reese, 1992) and Pain Catastrophic Scale (Sullivan, Bishop, & Pivik, 1995) were collected and analyzed using structural equation modeling in Amos21 software.

The results showed that the model has a good fit with the observed data (df2c <3, GFI, AGFI and CFI> 0.90 and RMSEA <0.08). Chronic pain, pain-related fear, anxiety sensitivity, catastrophic pain, and eating behaviors can explain 29.6% of the variance in body mass index. 55.2% of the variance of eating behaviors is explained by chronic pain, pain-related fear, anxiety sensitivity, and catastrophic pain.

To prevent and treat obesity in people with pain, the variables of pain-related fear, anxiety sensitivity, catastrophic pain and eating behaviors should be targeted.

The purpose of this study was to compare the effectiveness of acceptance & commitment therapy (ACT) with logotherapy (LT) on pain catastrophizing & quality of life in women with breast surgery experience.

This was a semi-experimental study with a pretest-posttest, controlled design with follow-up. The study population consisted of all women with breast cancer who were undergoing postmastectomy radiotherapy in Tabriz in 2022. In total, 45 women were selected by a purposive sampling method, and divided into three groups, 15 each. The ntervention groups received their respective treatments over 8 sessions of 1.5 hours. The control group did not receive any intervention. The research tools were the 13-question questionnaires of pain catastrophizing by Sullivan et al and the 36-question quality of life questionnaires. Data were analyzed with repeated measures analysis of variance.

In the pretest, mean and standard deviation of ACT for pain catastrophizing was (40/00±4/97) & for quality of life was (39/93±4/72); in LT for for pain catastrophizing was (39/07±4/31) & for quality of life was (40/73±5/02); and in the control group for pain catastrophizing was (39/47±4/29) & for quality of life was (40/33±3/69). Both treatments compared to the control group, reduced pain catastrophizing and increased quality of life of patients after the test (p<0.001). In the follow-up phase, the effect of these two treatments on pain catastrophizing and quality of life was lasting (p<0.001). The effect of these two treatments on pain catastrophizing and quality of life at posttest and follow-up was not different (p>0.05).

acceptance & commitment therapy & logotherapy  Reduces the pain catastrophizing and increases quality of life in women with breast surgery experience.

Cancer is one of the most common diseases in the world today that in addition to causing physical problems causes psychological problems for patients. One of these problems is pain catastrophizing.

The purpose of this study was to investigate the role of psychological resilience and mindfulness in predicting pain catastrophizing through mediating role of positive emotions in patients with cancer.

This study was a descriptive and correlational research. The statistical population included all Adult cancer patients (over 18 years old) in Kerman in summer and autumn of 2021, that a total of 141 patients were selected as the sample using purposive sampling. For data collection, Standard Pain Catastrophizing Scale, PANAS Positive Affect Schedule, short form of the Freiburg Mindfulness Questionnaire and Connor and Davidson Resilience Questionnaire, were used. For data analysis, path analysis and Pearson correlation methods were applied by using AMOS software version 24 and SPSS version 23.

Results showed that the direct path of resilience (-0.27) and positive emotions (-0.32) to pain catastrophizing and direct path of resilience (0.24) and mindfulness (0.16) to positive emotions were significant. Also, the results of path analysis showed that the final model of the research had the goodness of fit (CMIN=0.373, NFI=0.99).

The results showed that positive emotions mediate the prediction of pain catastrophizing based on psychological resilience and mindfulness. It is suggested that therapists and cancer-related institutions include treatment programs related to these factors.

Aims and

The aim of the present study was to compare the efficacy of MBCT with ACT on intensity of pain catastrophizing & resilience of patients with spinal cord injury.

The method of this study was semi-experimental with pre-test, post-test and follow up with the control group. The population of the study consisted of patients with spinal cord injury who referred to welfare counseling centers in Tabriz in year 2021. In total, 45 people, They were selected by using simple random sampling and randomly divided into three groups. The experimental groups received their group-specific treatment in 8 sessions 1.5 hours. Measuring instruments were pain catastrophizing of sullivan et al and conner and davidson resilience questionnaires. Analysis of findings through repeated measures analysis of variance & Bonferroni post hoc test.

In the pretest, mean and standard deviation of MBCT for pain catastrophizing was (38/33±4/63) & for resilience was (42/80±4/69); in ACT for for pain catastrophizing was (37/53±4/71) & for resilience was (42/20±4/57); and in the control group for pain catastrophizing was (37/93±4/83) & for resilience was (43/73±4/60). Both treatments compared to the control group, reduced pain catastrophizing and increased resilience of patients after the test (p<0.001). In the follow-up phase, the effect of these two treatments on pain catastrophizing and resilience was lasting (p<0.001). The effect of these two treatments on pain catastrophizing and resilience at posttest and follow-up was not different (p>0.05).

MBCT and ACT increased the acceptance of the disease in patients with spinal cord injury; thus, they can be considered useful treatment strategies to improve the mental status of this patients.

The research design was an experimental pretest-posttest with a control group. At first, 40 hospitalized men in a treatment center were selected by using the purposive sampling method. The experimental group was treated for eight 45-minute sessions by training logotherapy. All subjects completed the questionnaire at the beginning of the study, immediately after the intervention, and one month after the treatment (one-month follow-up). For data analysis, 1-way analysis of variance was used.

The results indicated that logotherapy in the experimental group was more effective than the control group in reducing death anxiety, pain catastrophizing, pain acceptance, and severity of pain in prostate cancer patients. The follow-up results also showed that the effect of logotherapy was sustained on death anxiety, pain catastrophizing, pain acceptance, and severity of pain in prostate cancer patients.

The results showed that Logotherapy has an effect on death anxiety, pain catastrophe, pain acceptance and pain intensity in patients with prostate cancer

Irritable bowel syndrome is the most common, expensive, and debilitating gastrointestinal dysfunction. Psychological factors have a profound effect on its onset, duration and severity. This study aimed to compare the effectiveness of mindfulness based cognitive therapy and Iranian-Islamic positive therapy on pain catastrophizing and symptom severity in women with irritable bowel syndrome.

In this study, semi-experimental research was done on three groups with the two-step plan of pre and post-test.The study sample consisted of 45 women with irritable bowel syndrome in the age range of 18 to 50 years in 2019 which were selected by purposive sampling based on inclusion and exclusion criteria with random assignment in three groups (one control and two experimental groups). To measure the research variables, ROME III diagnostic tool, the diagnostic structured interview for DSM-V-RV (SCID-I), Pain Catastrophizing Scale (PCS) and Bowel Symptom Severity and Frequency (BSS-FS) questionnaire were used in pre-test and post-test phases were used. The groups of mindfulness based cognitive therapy and Iranian-Islamic positive therapy were treated for 8 sessions and the control group remained in the waiting list. Data were analyzed using SPSS23 software and ANCOVA test.

The results showed that there was a significant difference between mindfulness based cognitive therapy and Iranian-Islamic positive therapy with control group in pain catastrophizing (p < 0.01) and severity of symptoms (P < 0.01), but no significant difference was seen between the two treatments (p>0.05).

Based on the findings of this study, it seems that mindfulness based cognitive therapy and Iranian-Islamic positive therapy can be used as a psychological treatment to reduce the catastrophizing and severity of symptoms in women with irritable bowel syndrome.

Chronic physiological diseases can cause psychological damage to people with the disease. according to this the present study was conducted aiming to investigate the effectiveness of Mindfulness Therapyon sleeping quality and pain catastrophizing in the women suffering from osteoporosis in the city of Isfahan.

The research method was quasi-experimental with pretest, posttest, control group and a 45-day follow-up stage. The statistical population of the study included all female patients with osteoporosis in the city of Isfahan in a period of four months beginning from the third quarter of the year in 2018-19 who referred to private orthopedic clinics. The sample size in the study was 26 patients with osteoporosis who were selected through convenient sampling method and they were randomly replaced into experimental and control groups (13 patients in the experimental and 13 in the control groups). The experimental group received ninety-minute therapeutic interventions related to mindfulness during two months once a week while the control group didn’t receive any psychological intervention during the study. Then the people in both groups took the posttest. The follow-up stage was administered after 45 days. The applied instruments included, pain catastrophizing scale (Solivan, et.al, 1995) and Petersbourg sleeping quality questionnaire (Boys, Reynolds, Bermen and Kopfer, 1989). After collecting questionnaires and extracting raw data, data analysis of this study was done via SPSS23 by descriptive statistics and repeated measurements ANOVA.

The results of the study showed that Mindfulness Therapyhas significant effect on sleeping quality (0.77) and pain catastrophizing (0.83) in the women with osteoporosis (p<0.001).

Based on this, we can use mindfulness therapy to improve the sleeping quality and pain catastrophizing in patients with osteoporosis.

People respond to chronic pain in various ways and pain adjustment is not the same in different individuals. The aim of the current study is the assessment of the level of chronic pain adjustment in rheumatoid arthritis (RA) patients based on the quality of life, physical disability, and the level of their depression. In addition, the role of three variables, pain catastrophizing, fear of movement, and self-efficacy in a relationship with chronic pain adjustment was assessed.

In this cross-sectional study, 123 RA patients who had chronic pain and were over 18 years old were included. Patients were attending the outpatient rheumatology clinic, Shariati Hospital from May 2017 until May 2018. Patients were assessed by the Short-Form Health Survey (SF-36), Pain Self-Efficacy Questionnaire (PSEQ), Physical Disability Questionnaire (PDQ), Depression, Anxiety and Stress Scales (DASS), Tampa Scale for Kinesiophobia (TSK), and Pain Catastrophizing Scale (PCS). Data were analyzed by Pearson correlation and multiple linear regression methods.

Our results showed that there is an association between self-efficacy, fear of movement, and pain catastrophizing with chronic pain adjustment (P<0.01). According to the multiple linear regression analysis, fear of movement and pain catastrophizing are in a correlation with the physical disability. The finding demonstrated that self-efficacy and pain catastrophizing variables influence the patient’s depression. In addition, pain catastrophizing, fear of movement, and self-efficacy influenced the patient’s physical and mental quality of life.

The relationship between pain and physical disability and other aspects of chronic pain adjustment are adjusted by pain beleifs and pain coping strategies.

Health literacy is the ability to receive, process, understand and understand health-related information and services in order to make appropriate health decisions. The health literacy for breast cancer patients plays an important role in accessing adequate diagnostic and therapeutic measures. The aim of this study was to investigate the mediating role of Pain catastrophizing in the relationship between health literacy and specific quality of life among patients with breast cancer.

 The present study was a cross-sectional and correlational study in terms of method and was basic science in terms of purpose. In this cross-sectional study, 213 consecutive patients with breast cancer were selected based on the inclusive and exclusive criteria. Then, the patients completed questionnaires of Iranian version of health literacy, quality of life and Pain catastrophizing. Data were analyzed using SPSS and LISREL software by path analysis model.

All components of health literacy and specific quality of life were significantly correlated with Pain catastrophizing. Also there was a significant association between health literacy and specific quality of life. The findings showed that as far as the health literacy is Increase, the Pain catastrophizing scores significantly are also decrease.

It seems that Pain catastrophizing plays the mediating role between health literacy and specific quality of life among patients with breast cancer. Therefore, it is necessary to consider the relational model between these factors for development of psychological protocols and integrating those protocols in therapeutic plans for breast cancer patients.
