Background: In epidemiological surveillance of mental health there is good reason to also include scales that measure the presence of well-being rather than merely symptoms of ill health. The Mental Health Continuum-Short Form (MHC-SF) is a self-reported scale to measure emotional, psychological and social well-being and conduct categorical diagnosis of positive mental health. This particular instrument includes the three core components of the World Health Organization's definition of mental health and had previously not been psychometrically evaluated on adolescents in China.Methods: In total 5,399 students (51.1% female) from schools in the urban areas of Weifang in China were included in the study (mean age = 15.13, SD = 1.56). Participants completed a comprehensive questionnaire with several scales, among them the MHC-SF. Statistical analyses to evaluate reliability, structural validity, measurement invariance, presence of floor and ceiling effects and to some extent external validity of the MHC-SF were carried out.Results: The Cronbach's α coefficients for sub-scales as well as the total scale were all above 0.80 indicating good reliability. Confirmative factor analysis confirmed the three-dimensional structure of the Chinese version of MHC-SF and supported the configural and metric invariance across gender and age. Noteworthy ceiling effects were observed for single items and sub-scales although not for the total scale. More importantly, observed floor effects were negligible. The stronger correlation found between MHC-SF and Minneapolis-Manchester Quality of Life Instrument (as measure of positive mental health) than between MHC-SF and Hospital Anxiety Depression Scale (as measure of mental illness and distress) yielded support for external validity.Conclusion: In conclusion, the main findings of this study are in line with studies from other countries that evaluated the psychometric properties of the MHC-SF and show that this instrument, that includes the three core components of the WHO definition of mental health, is useful in assessing positive adolescent mental health also in China.

Objective • To investigate the value of comprehensive rehabilitation therapy in chronic obstructive pulmonary disease (COPD) and its effect on improvement in patients’ inflammation. Methods • A total of 174 patients with acute COPD exacerbation in the Affiliated Hospital of Hebei University in China from March 2020 to January 2022 were selected as research subjects. They were divided into control, acute and stable groups according to the random number table method (n=58 in each group). The control group was given conventional treatment; the acute group started comprehensive rehabilitation treatment in the acute phase; in the stable group, comprehensive rehabilitation treatment was initiated in the stable period after the condition was stabilized with conventional treatment. Tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and pulmonary function were measured before and after treatment, with the forced expiratory volume in 1 second (FEV1), forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio, and peak expiratory flow rate (PEF). A 6-min walk test (6MWD) was performed on the patient, and the ability to perform activities of daily living (ADL), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess patients’ ability to perform ADL and psychology. Finally, the incidence of adverse events (AEs) in patients was recorded and a quality of life (QoL) survey was completed. Results • The 6MWD test, ADL, FEV1, FEV1/FVC and PEF were elevated in the acute and stable groups compared with the control group, whereas shortness of breath, TNFα, hs-CRP and IL-6 were decreased (P<.05). SAS and SDS scores were reduced in the acute and stable groups after treatment (P < .05), while there was no change in the control group (P>.05). In addition, QoL was higher in the acute and stable groups (P < .05). The improvement of all indicators in the acute group was better than in the stable group (P<.05). Conclusion • Comprehensive rehabilitation therapy can improve the exercise capacity and lung function of patients with COPD, reduce inflammation, and improve patients’ negative psychology.
