Methods: As it is a single group design that adopts common-person equating method, a total of 460 patients with MDD completed the PHQ-9, GAD-7 and HADS at the same time. Rasch analysis was used to filter out invalid participants, investigate the psychometric properties of test items and participants, link the PHQ-9 and HADS-D as well as GAD-7 and HADS-A, and produce conversion tables respectively.
Objectives: The objective of this research was to verify the psychometric characteristics of the Chinese Adaptation of self-report HAMD-6.
Methods: Outpatients and inpatients who met the DSM-5 criterion for major depressive disorder (MDD) were evaluated by the Chinese self-report HAMD-6, seventeen items of Hamilton Depression Rating Scale (HAMD-17), Patient Health Questionnaire Depression Scale (PHQ-9) and Improved Clinical Global Impression Scale (iCGI-S). The internal consistency reliability, retest reliability, criterion validity and construct validity of the Chinese self-report HAMD-6 were tested.
Article Synopsis
- Biofilms are common habitats for microbes in drinking water systems, and changes in environmental conditions can cause these biofilms to detach, affecting water quality.
- The study found that higher concentrations of chloramine increased biofilm detachment, with 1.0 mg/L resulting in the most biomass loss; starvation treatment also led to greater detachment rates despite lower overall biomass.
- Analysis showed significant differences in microbial diversity between detached and stubborn biofilms, with starvation increasing the presence of certain bacteria and antibiotic resistance genes (ARGs), highlighting potential health risks in drinking water.
Objective: This study aimed to evaluate the psychometric properties of the Chinese version of the Clinically Useful Depression Outcome Scale (CUDOS).
Methods: One hundred ninety patients with major depressive disorder (MDD) according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria were recruited to the study. The English version of the CUDOS was translated into Chinese using a forward and backward translation method, which was according to the guidelines of adaptation and validation of instruments in cross-cultural health care research.
