A control study on pain characteristics and influencing factors in patients with depressive disorders-based on a 5-year follow-up report from the epidemiological survey of mental disorders in Shandong Province, China.

BACKGROUND: This study extends from the 2015 Shandong Province Epidemiological Survey of Mental Disorders in adults aged 18 and above. Over five years, it investigates pain characteristics and influencing factors in individuals with depressive disorders in Shandong Province. METHODS: The study encompasses 871 individuals who met DSM-IV criteria for depressive disorders in 2015. Using 1:1:1 matching by gender, age, and residence, 825 non-afflicted individuals were selected as high-risk controls, and 825 screening-negative individuals became low-risk controls. A follow-up study in 2020 involved 1848 participants. Survey tools included a general information questionnaire, General Health Questionnaire-12 (GHQ-12), SCID-I/P, Global Pain Scale (GPS), Quality of Life Questionnaire (QLQ), PSQI, MoCA, and clinical data questionnaire. RESULTS: GPS scores in the current depressive group were higher than in non-current depressive group (Z = 14.36, P < 0.01). GPS scores in study group exceeded those in high-risk and low-risk control groups (H = 93.71, P < 0.01). GPS scores in non-remission group were higher than in the remission group (Z = 8.90, P < 0.01). Regression analysis revealed positive correlations between GPS scores and physical illnesses, current depression, incumbency, GHQ-12 total score, and PSQI total score. Negative correlations were observed with QLQ total score and MoCA total score. LIMITATIONS: The study could not assess pain during the 2015 survey, limiting controlled pain analysis before and after five years. CONCLUSION: Depression sufferers may experience prolonged heightened pain, potentially relieved when depression subsides. Individual pain is influenced by depression, physical illnesses, sleep quality, quality of life, cognitive function, gender, residence, and occupation.

The Relationship Between Negative Life Events and Nonsuicidal Self-Injury Among Chinese Adolescents: A Moderated-Mediation Model.

Objective: This study aimed to investigate whether anxiety mediates the relationship between negative life events and nonsuicidal self-injury (NSSI) in adolescents and whether this mediating role is moderated through social support. Methods: The model consisted of an anonymous questionnaire survey of 506 Chinese adolescents (253 boys and 253 girls, mean age 15.11 years (SD = 1.83, range 11-18 years)). Self-designed questionnaires were used to collect demographic data. The frequency of NSSI, state anxiety, and social support degree of adolescents was assessed by the Adolescent Life Events Scale, the Chinese version of the Beck Anxiety Inventory, and the social support scale, respectively. Results: Negative life events were significantly and positively correlated with anxiety and the frequency of NSSI, and anxiety was significantly and positively correlated with the frequency of NSSI. The positive association between negative life events and the frequency of NSSI among adolescents was mediated by anxiety after controlling for demographic variables. Furthermore, this mediated relationship was moderated by social support. Conclusion: Anxiety was a potential mechanism linking negative life events to NSSI in adolescents and low social support important risk factor for amplifying this indirect effect. Our findings provide an empirical basis for reducing NSSI in adolescents.

Reliability and Validity of the Chinese Version of the Cognitive Distortions Questionnaire (CD-Quest) in College Students.

BACKGROUND The aim of this study was to evaluate the reliability and validity of the Chinese version of the Cognitive Distortions Questionnaire (CD-Quest) among Chinese college students. MATERIAL AND METHODS A total of 460 college students from Jining were recruited in the study. Sample 1, including 239 college students, was tested for item analysis and exploratory factor analysis. Sample 2, including 221 college students, was tested for confirmatory factor analysis and criterion validity. The criterion validity was tested using the Negative Automatic Thoughts questionnaire (ATQ) and Dysfunctional Attitudes Scale (DAS). Test-retest reliability was evaluated in 40 college students from sample 1 with  4 weeks interval. RESULTS The corrected item-total correction (ITC) ranged from 0.675 (emotional reasoning) to 0.829 (unfair comparison). Exploratory factor analysis revealed the variance of the CD-Quest items was unidimensional, and it explained 55.261% of the data variance. Confirmatory factor analysis indicated all regression coefficients were higher than 0.4. The criterion validity was excellent, as shown by the relationships among CD-Quest, DAS, and ATQ (r=0.447, 0.566, respectively). Cronbach's alpha coefficient was 0.941 and the test-retest reliability was 0.928. CONCLUSIONS The Chinese version of CD-Quest had good reliability and validity, suggesting it is a reliable tool to evaluate cognitive distortion of Chinese college students.

Correlation of clinical features with hs-CRP in TRD patients.

Correlation of clinical features with hypersensitive C-reactive protein (hs-CRP) in patients with treatment-resistant depression (TRD) was investigated. The severity of disease in 103 TRD patients and 103 non-TRD patients was evaluated using the Hamilton Depression Scale (HAMD)-17. The levels of hs-CRP in both groups were detected via immunofluorescence. Clinical features and differences in hs-CRP before and after treatment in both groups were analyzed, and correlation of baseline hs-CRP level with clinical features of TRD patients was also analyzed. Moreover, the relationship between hs-CRP and occurrence of TRD was analyzed using logistic regression analysis, and the diagnostic value of hs-CRP in TRD was evaluated using the receiver operating characteristic (ROC) curve. The onset age in the TRD group was lower than that in the non-TRD group, the education in the TRD group was shorter than that in the non-TRD group, the total course of disease in the TRD group was longer than that in the non-TRD group, and both baseline and post-treatment hs-CRP level in the TRD group (12.05±5.79 and 9.02±3.71 mg/l) were higher than those in the non-TRD group (7.85±2.85 and 6.10±2.74 mg/l) (p<0.05). The HAMD score (r=0.338, p=0.031), anxiety/somatization factor score (r=0.465, p=0.015) and sleep disorder (r=0.387, p=0.029) of TRD patients were positively correlated with the hs-CRP level, but the onset age (r=-0.59, p=0.009) was negatively correlated with the hs-CRP level. Logistic regression analysis revealed that the baseline hs-CRP was included into the TRD regression equation [odds ratio (OR) =2.834, 95% confidence interval (CI) =1.723-4.886], and the area under the ROC curve was 0.893 (p<0.05, 95% CI=0.852-0.933). In the TRD group, the course of TRD in patients was longer, the onset of disease was earlier and the educational level was lower than that in the non-TRD group. Therefore, the level of hs-CRP can serve as a reference for the diagnosis of TRD.
