This study aimed to determine whether the relationship between pain resilience and pain catastrophizing in older patients after total knee arthroplasty (TKA) was mediated by cognitive emotion regulation strategies (CERS) and pain management self-efficacy (PMSE). Convenience cluster sampling was used in this cross-sectional study to recruit 382 older adults. The results revealed that pain catastrophizing was negatively correlated with pain resilience, adaptive CERS, and PMSE; however, it was positively correlated with maladaptive CERS (all p < 0.01). Mediation analysis revealed that both CERS (adaptive and maladaptive) and self-management independently and sequentially mediated the relationship between pain resilience and pain catastrophizing in older patients who underwent TKA. These findings demonstrate that CERS (adaptive and maladaptive) and PMSE play chain-mediating roles in the correlation between pain resilience and pain catastrophizing in older patients after TKA.

OBJECTIVE: This study aimed to explore the pathways between family functioning and mental health in people with neuropathic pain, as well as to discuss the mediating role of pain intensity, self-perceived burden, pain catastrophizing, and functional status.
METHODS: Cross-sectional design reported using the STROBE guidelines.
METHODS: A total of 277 people with neuropathic pain completed face-to-face questionnaires to evaluate family functioning, pain intensity, pain catastrophizing, self-perceived burden, functional status, and mental health. Structural equation modeling (SEM) was constructed to analyze the pathways between these variables.
RESULTS: The positive total effect between family functioning and mental health was significant and partially mediated by self-perceived burden, pain catastrophizing, and functional status. In addition, better family functioning was associated with higher pain intensity, which worsens self-perceived burden, pain catastrophizing, and functional status, masking 23.68% of the positive effects between family functioning and mental health.
CONCLUSIONS: Better family functioning was associated with better mental health, as explained by reduced self-perceived burden, reduced pain catastrophizing, and improved functional status. However, this benefit may be partially masked by the relationship that better family functioning explains higher pain intensity.
CONCLUSIONS: Nurses\' comprehensive assessment and management of neuropathic pain from both the family and individual levels, such as family functioning, pain intensity, self-perceived burden, pain catastrophizing, and functional status, may be beneficial in promoting patients\' mental health. In addition, it is necessary to identify why good family functioning is associated with higher pain intensity and intervene in this regard.

BACKGROUND: There is a lack of research on the relationship between pain catastrophizing, kinesiophobia, and physical activity (PA) in people with haemophilia (PWH), and the underlying mechanisms connecting these variables remain unclear.
OBJECTIVE: The study\'s aim was to clarify the roles of kinesiophobia and self-efficacy in the relationship between pain catastrophizing and PA in PWH.
METHODS: This cross-sectional study included adult PWH at the Haemophilia Centre of a Tertiary hospital in Beijing, China. The following questionnaires were used to collect data: the general information, the International Physical Activity Short Questionnaire, the Pain Catastrophizing Scale, the Tampa Scale of Kinesiophobia Scale, and the Exercise Self-Efficacy Scale.
RESULTS: The study included a total of 187 PWH, including 154 having haemophilia A and 33 having haemophilia B. The median interquartile range of PA was 594 (198, 1554) MET-min/wk. There were significant differences in PA of patients based on age stage, treatment modality, highest pain score within the last seven days, and presence of haemophilic arthropathy (p < .05). It was showed that pain catastrophizing could directly predict PA (p < .001), accounting for 38.13% of the total effect. Pain catastrophizing also had indirect effects on PA through the mediating factors of kinesiophobia or self-efficacy, and through the chain-mediating effect of kinesiophobia and self-efficacy, accounting for 38.40%, 17.07%, and 6.40%, respectively.
CONCLUSIONS: The study discovered that PWH have limited PA due to pain catastrophizing. This not only directly affects their activity but also indirectly influences it through kinesiophobia and self-efficacy.

This cross-sectional study aimed to investigate the relationship between family functioning, pain intensity, self-perceived burden, and pain catastrophizing. Moreover, we also wanted to explore the multiple mediating roles of pain intensity and self-perceived burden. From October 2022 to March 2023, 252 Chinese people with neuropathic pain completed face-to-face questionnaires to assess family functioning, pain intensity, self-perceived burden, and pain catastrophizing. Data analysis was done using descriptive statistics and a structural equation model. The results showed better family functioning was significantly associated with more intense pain, less self-perceived burden, and less pain catastrophizing. Mediation analysis showed that family functioning could indirectly affect pain catastrophizing through pain intensity and self-perceived burden in addition to a direct effect on pain catastrophizing. Moreover, the mediating variable of pain intensity played a masking role. These findings suggest that good family functioning can effectively reduce the self-perceived burden and pain catastrophizing in patients with neuropathic pain. However, family functioning cannot show its maximum effectiveness, and it may be necessary to construct a model of family functioning suitable for patients with neuropathic pain in the future.

UNASSIGNED: To examine whether exercise self-efficacy mediates the contributions of pain catastrophizing and kinesiophobia to exercise adherence in patients after total knee arthroplasty.
UNASSIGNED: A cross-sectional study design was conducted. A total 211 post-total knee arthroplasty patients were recruited from three orthopedics units of a tertiary hospital in China. Participants were invited to complete questionnaires on pain catastrophizing, kinesiophobia, exercise self-efficacy, and exercise adherence. Mplus 8.3 software was used to construct mediation models.
UNASSIGNED: Pain catastrophizing and kinesiophobia were negatively correlated with exercise adherence (r = -0.509, r = -0.605, p < 0.001 respectively), while exercise self-efficacy were positively associated with exercise adherence (r = 0.799, p < 0.001). The results found exercise self-efficacy mediated the correlations of pain catastrophizing and kinesiophobia with exercise adherence after adjusting for demographic and clinical covariates. Pain catastrophizing indirectly affected patients\' exercise adherence through its effect on exercise efficacy (indirect effect: -0.412), while Kinesiophobia is directly associated with exercise adherence and also indirectly through exercise self-efficacy (direct effect: -0.184, indirect effect: -0.415).
UNASSIGNED: Patients after total knee arthroplasty who have high levels of psychological distress (pain catastrophizing and kinesiophobia) are vulnerable to be non-adherent to exercise behaviors. Exercise self-efficacy explains the effects of pain catastrophizing and kinesiophobia on exercise adherence and may be a key target for measures to improve exercise behaviors in patients after total knee arthroplasty.

Psychological therapies are important for comprehensive chronic orofacial pain (COFP) treatment. This study is to validate the effects of psychological factors on oral health-related quality of life (OHRQoL) among COFP patients in China. Pain catastrophizing, which is a subjective cognitive emotion used to manage the psychological aspects of pain among COFP patients, was examined in relation to COFP severity and OHRQoL. All 479 participants were recruited in Changsha, Hunan Province, China. Cronbach\'s alpha coefficients (0.868-0.960), composite reliability scores (0.924-0.969), and average variance extracted from each construct (0.555-0.753) all indicated a good model fit. Pearson\'s correlation analysis showed that age and education status have a positive correlation with COFP severity, pain catastrophizing, and anxiety. COFP severity was related to anxiety, depression, and COFP-OHRQoL. Pain catastrophizing was related to employment status. Anxiety and depression symptoms indirectly mediated the correlation between COFP severity and COFP-OHRQoL. As a second-stage moderator, pain catastrophizing moderated the mediating effects of anxiety symptoms and depression symptoms. Our findings suggest that anxiety, depression, and pain catastrophizing should be evaluated jointly to improve COFP-OHRQoL among COFP patients. This evidence will help therapists to comprehensively treat patients for the best treatment effect.

UNASSIGNED: Knee osteoarthritis (KOA) is a painful chronic disorder. Evidence has shown that a history of chronic pain plays an important role in shaping empathy. Empathy, a valuable indicator of social functioning that refers to an individual\'s ability to share the experiences of others, however, has been overlooked in KOA patients. This study aimed to investigate empathy and its association with clinical pain in KOA patients.
UNASSIGNED: KOA patients (n=47) and healthy controls (HCs, n=44) completed two empathy-for-pain tasks: a pain judgment task in which participants judged whether a person in an image felt pain or not, and a pain rating task in which they estimated pain intensity for themselves and others. The Interpersonal Reactivity Index was used to measure participants\' trait empathy, and clinical severity and psychological factors were assessed using relevant instruments.
UNASSIGNED: Compared to HCs, KOA patients showed higher accuracy when judging pain and non-pain images and reported overall higher pain intensity when rating for themselves and others. KOA patients also showed greater personal distress than HCs in terms of their self-reported empathy. Moreover, pain catastrophizing particularly mediated the relationship between pain severity and pain ratings for others, and depression, anxiety, and pain catastrophizing all mediated the association between pain severity and empathy-induced personal distress.
UNASSIGNED: These findings suggest that patients with KOA have increased empathy, demonstrated by elevated sensitivity to pain-related scenes and intense emotional responses.

UNASSIGNED: Although comorbidity of major depressive disorder (MDD) and chronic pain (CP) has been well-studied, their association with pain catastrophizing is largely elusive. This study aimed to investigate the potential effects of pain catastrophizing in patients with a comorbidity.
UNASSIGNED: In total, 140 participants were included in this study and divided into three groups according to the Diagnostic and Statistical Manual of Mental Disorders and the International Association for the study of pain (i.e., the comorbidity group: patients with depression with chronic pain, n = 45; depression group: patients with depression without chronic pain, n = 47; and healthy controls: n = 48). The Hamilton Depression Rating Scale (HAMD)-24 and Hamilton Anxiety Rating Scale (HAMA)-14 were used by professional psychiatrists to evaluate the severity of depression and anxiety. Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI) were conducted by patients\' self-report to assess the symptom severity. The pain intensity numerical rating scale (PI-NRS) was used to assess the pain intensity. Pain Catastrophizing Scale (PCS) and Pain Anxiety Symptoms Scale (PASS) were used to estimate pain-related negative thinking.
UNASSIGNED: The results showed that PASS and PCS scores were significantly different among the three groups. Particularly, the scores in the comorbidity group were the highest. The Pearson correlation analysis revealed a positive correlation between PCS (including the patients\' helplessness, magnification, rumination, and total scores) and the severity of depression symptoms, anxiety symptoms, and pain intensity (P < 0.05). A stepwise regression analysis further demonstrated that the total PCS score, high monthly income level, and BDI score had positive impacts on PASS (P < 0.05). We also found that the total BDI score, disease course ≥1 year, and pain intensity had positive effects on PCS (P < 0.05), whereas years of education (≤ 12 years) had a negative effect on PCS (P = 0.012). In all, we have clearly demonstrated that PCS and PASS could serve as potentially predictive factors in patients suffering from comorbidity of MDD and CP.
UNASSIGNED: Our results suggested that the pain-related catastrophic thinking and anxiety were more severe in the comorbidity group than in MDD-only group and healthy group. Pain-related catastrophizing thoughts and anxiety may have potentially effects on the comorbidity of depression and chronic pain.

BACKGROUND: Pain catastrophizing in preoperative total knee arthroplasty (TKA) patients is associated with several poorly characterised factors in the literature. This study investigated the current state and associated factors of preoperative pain catastrophizing in patients undergoing TKA.
METHODS: This descriptive cross-sectional study was conducted at the orthopedics ward of two tertiary hospitals in Lanzhou, China. Pain catastrophizing was measured using the Chinese versions of the Pain Catastrophizing Scale, Short Form-36 (physical function domain), Numerical Rating Scale, Oxford Knee Score, Hospital Anxiety and Depression Scale, and Life Orientation Test-Revised.
RESULTS: The study included 360 participants. Preoperative TKA pain catastrophizing in all patients was high, with a mean score of 24.92 (SD: 12.38). The stepwise multiple linear regression analysis revealed anxiety (β = 0.548, P < 0.01), education level (β =  - 0.179, P < 0.01), physical function (β =  - 0.156, P < 0.01), and pain intensity during activity (β = 0.105, P = 0.015) as associated factors for pain catastrophizing, possibly explaining 51.2% of the total variation (F = 95.149, P < 0.01).
CONCLUSIONS: Anxiety was the most relevant factor for pain catastrophizing in patients with preoperative TKA. Lower education levels, poor physical function, and stronger pain intensity during the activity were also associated with pain catastrophizing.

Purpose: This study aimed to evaluate the global scientific output of research on pain catastrophizing and explore the hotspots and frontiers from 2010 to 2020 using bibliometric methods. Methods: Publications regarding pain catastrophizing published from 2010 to 2020 were extracted from the Web of Science Core Collection. CiteSpace was used to analyze the number of publications, countries, institutions, journals, authors, cited references, and keywords using standard bibliometric indicators. Results: A total of 1,576 publications on pain catastrophizing were retrieved from 2010 to December 31, 2020. The number and rate of the annual publications gradually increased totally. Pain (130) was the most productive journal. Meanwhile, Pain ranked first in the frequency (1,432) and centrality (0.31) of the cited journals. The most productive country and institution in this frequency field were the United States (642) and the University of Washington (73), respectively. Jensen MP (34) was the most prolific author, and Sullivan MJL (1,196) ranked first among the cited authors. In the ranking of frequency in the cited references, the first article was a critical review about pain catastrophizing published by Quartana (100). The keyword \"Low back pain\" had the highest frequency (556). \"Total hip\" was identified as a frontier research item for 2016-2020. Conclusion: The findings of this bibliometric study provide the current status and trends in the clinical research of pain catastrophizing and may help researchers to identify hot topics and explore new research directions in this field.
