ObjectiveTo evaluate the clinical reliability and validity of the Chinese version of the Patient Health Questionnaire-9 (C-PHQ-9) in patients with psoriasis.DesignCross-sectional study.SettingTertiary care centre.ParticipantsPatients with psoriasis who have not been diagnosed with depression (n=148; mean age 43.37±17.46 years; 31.19% female).Primary and secondary outcome measuresThe primary outcome measures considered in this study were the C-PHQ-9 and the Hamilton Depression Scale (HAMD). The American Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-V) was used as the gold standard for the diagnosis of depression. Cronbach’s α and test–retest reliability after 1 week were evaluated using reliability analysis, and criterion and structural validity were assessed using validity analysis. Receiver operating characteristic (ROC) analysis was performed to identify the best demarcation score and diagnostic accuracy.ResultsCompared with DSM-V (27.27%), both C-PHQ-9 (39.19%) and HAMD (31.01%) had higher rates for detecting depression. The mean completion time for C-PHQ-9 evaluation (2.02±0.84 min) was significantly less than that for HAMD (23.37±3.21 min, p<0.001). The Cronbach’s α coefficient for the C-PHQ-9 was 0.938. The correlation coefficients of the nine items with the total scale ranged from 0.540 to 0.854, and the mean inter-item correlation coefficients ranged from 0.376 to 0.933. After a week, the retest coefficient was 0.955 (p<0.01). Principal component factor analysis showed that C-PHQ-9 identified a unifactorial structure. The best cut-off point was 9 points, with a sensitivity of 98.00% and a specificity of 90.80%. The area under the ROC curve was 0.979 (95% CI 0.968 to 0.991).ConclusionC-PHQ-9 has good reliability and validity in patients with psoriasis and can be used for primary screening of patients with psoriasis and depression. This scale has obvious time and labour advantages over the HAMD and should be considered for use in clinical practice.

Background: Melasma is hyper-pigmentation of skin, usually seen in young female adults, and previous studies have established substantial psychosocial burden associated with this disease. Aim: To measure the frequency of depression in melasma patients and its correlation with severity of melasma Study Design: Descriptive cross-sectional study. Place and duration of study: Dermatology OPD, HIT Hospital Taxila from 1st January 2021 to 31st August 2021 Methods: One hundred consecutive patients of melasma diagnosed by a skin specialist were enrolled. Elderly patients aged >60 years, those with previous psychiatric disease or chronic illnesses and on long term streroids were not included. After getting written informed consent, enrolled patients were screened for depression using Patient Health Questionnaire 9 (PHQ-9) Results: There were 17 males and 83 females. The mean age was 41.5±8.14 years. On MASI scale for assessing severity of melasma, 38 patients scored mild, 51 scored moderate and 11 scored severe. Using Patient Health Questionnaire 9 (PHQ-9) in patients with melasma, 18 patients didn’t have depression, 38 had mild depression, 31 had moderate depression, 6 had moderately severe depression and 7 had severe depression. Conclusion: The frequency of depression is quite high in patients suffering from melasma. It indicates a need for prompt diagnosis, appropriate intervention at correct time to ensure patient’s compliance to therapy to improve his disease outcome. Keywords: Depression, Melasma, Frequency

Abstract Background Nurses’ palliative and hospice care-specific education is associated with the quality of palliative and hospice care that influences health outcomes of patients with life-limiting illnesses and their caregivers. However, China lacks measures available to assess nurses’ educational needs in palliative and hospice care. The End-of-Life Professional Caregiver Survey (EPCS) is a psychometrically reliable self-reporting scale to measure multidisciplinary professionals’ palliative and hospice care educational needs. This study was performed to explore the psychometric properties of the Chinese version of the EPCS (EPCS-C) among Chinese nurses. Methods We translated and culturally adapted the EPCS into Chinese based on Beaton and colleagues’ instrument adaptation process. A cross-sectional study design was used. We recruited 312 nurses from 1482 nurses in a tertiary hospital in central China using convenience sampling to complete the study. Participants completed the EPCS-C and a demographic questionnaire. Exploratory and confirmatory factor analysis was carried out to test and verify the construct validity of the nurse-specific EPCS-C. Cronbach’s alpha coefficient was used to appraise the reliability of the nurse-specific EPCS-C. Results A three-factor structure of EPCS-C was determined, including cultural, ethical, and national values; patient- and family-centered communication; and effective care delivery. The exploratory factor analysis explained 70.82% of the total variances. The 3-factor solution of the nurse-specific EPCS-C had a satisfactory model fit: χ2 = 537.96, χ2/df = 2.96, CFI = 0.94, RMSEA = 0.079, IFI = 0.94, and GFI = 0.86. Cronbach’s alpha coefficient of the overall questionnaire was 0.96. Conclusions The nurse-specific EPCS-C showed satisfactory reliability and validity to assess nurses’ palliative and hospice care educational need. Further research is required to verify the reliability and validity of the EPCS-C in a larger sample, especially the criterion-related validity.

BackgroundBecause of symptom overlap, there is uncertainty about the validity of depression rating scales in neurologic populations. The objectives of this study were to evaluate the validity of the Patient Health Questionnaire-9 (PHQ-9) for detecting Diagnostic and Statistical Manual–defined major depressive episodes in people with neurologic conditions.MethodsParticipants were recruited from outpatient clinics for multiple sclerosis, epilepsy, migraine, Parkinson disease, and stroke for this cross-sectional study. Participants were administered a questionnaire (this included the PHQ-9), chart review, and a follow-up telephone interview. The Structured Clinical Interview for Depression was used as the reference standard for psychiatric diagnoses. The performance of PHQ-9 was analyzed using sensitivity, specificity, diagnostic odds ratios (DORs), and receiver operator curve analysis.ResultsAll neurologic subpopulations had a specificity greater than 78% and sensitivity greater than 79% at a cut-point of 10. Using a random-effects model, the I-squared value was 13.7%, and Tau2 was 0.05, showing homogeneity across the neurologic subpopulations. The pooled DOR was 25.3 (95% confidence interval [CI] 14.9–42.8). Meta-analytic analysis found that for sensitivity, the pooled estimate was 90% (95% CI 81–97), and for specificity, it was 85% (95% CI 79–90).ConclusionsDespite theoretical concerns about its validity, the PHQ-9 performed well at its standard cut-point of 10. Consistent with the literature, being able to use a validated, brief tool that is available publicly should improve case finding of depression in neurologic populations. When considering clinical practicality along with the findings of this analyzed, this study confirmed that the PHQ-9 is valid in a general outpatient neurologic population.

Brace Questionnaire

Abstract Background: There is an increasing concern about the impact of bracing on the quality of life (QoL) of patients with adolescent idiopathic scoliosis (AIS). However, up to now, few multidimensional questionnaires on this impact are available in China. This cross-sectional study aimed to evaluate the reliability and validity of the Chinese version of Brace Questionnaire (C-BrQ).Methods: The BrQ was translated from Greek into Chinese with proper cross-cultural adaptation.An observational, cross-sectional study in Chinese patients with AIS was conducted to measure the temporal stability of C-BrQ using the intraclass correlation coefficient (ICC). The effects of ceiling and floor were evaluated and the reliability was verified by examining the internal consistency. The C-BrQ domains were compared with the domains in C-SRS-22 using Pearson's correlation coefficient to assess the concurrent validity.Results: A total of 208 patients were included in the study. The results of test-retest reliability for each dimension of C-BrQ were desirable. The floor or ceiling effects were not demonstrated in the C-BrQ and C-SRS-22. Satisfactory internal consistency was found in all the C-BrQ domains. Most C-BrQ and C-SRS-22 domains showed satisfactory correlation coefficients, except when vitality and school activity in C-BrQ were compared with self-image, mental health and management satisfaction in C-SRS -22, respectively.Conclusion: C-BrQ is reliable in evaluating the QoL of AIS patients receiving brace treatment.Trial registration: This study protocol was registered with the Chinese Clinical Trial Registry (Registration number: ChiCTR1800018310).
