- Validation of the Chinese version of the 12-Item multiple sclerosis walking scale in individuals with multiple sclerosis: a psychometric and item response theory analysis
He Zhang, Nabi Nazari
BMC Psychology, 2025
BACKGROUND: The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is widely used to assess patient-perceived walking disability in individuals with multiple sclerosis (MS). Despite its international application, a validated Mandarin version has been lacking. This study aimed to translate and validate the Chinese version of the MSWS-12 and examine its psychometric properties using both classical test theory (CTT) and item response theory (IRT) approaches. METHODS: The MSWS-12 was translated into Chinese following international guidelines, including forward and backward translation, expert panel review, and cognitive debriefing. Cognitive debriefing was conducted with 20 individuals with MS (10 urban, 10 rural; 40% with a high school education or lower), confirming that all items were clear, culturally relevant, and conceptually equivalent. Participants were recruited from neurology clinics and included adults with clinically confirmed MS who had sufficient cognitive and physical function to complete the self-report instrument. Measurement properties were evaluated in accordance with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline, including internal consistency, test-retest reliability, structural validity, measurement invariance, and item-level analysis using the Graded Response Model (GRM). RESULTS: Participants (N = 292) had a mean age of 41.72 years (SD = 5.23), with 60.6% identifying as female, and represented a diverse educational backgrounds. The Chinese version of the MSWS-12 demonstrated excellent internal consistency (Cronbach's α = 0.92; McDonald's ω = 0.91) and strong test-retest reliability (intraclass correlation coefficient [ICC] = 0.91, 95% CI [0.86, 0.94]), indicating high temporal stability. CFA supported a unidimensional structure with excellent model fit (CFI = 0.987, TLI = 0.984, IFI = 0.987, SRMR = 0.032, RMSEA = 0.038. 90% CI [0.015, 0.056]). Measurement invariance was confirmed across sex, residency, and disease duration at configural, metric, scalar, and strict levels (ΔCFI < 0.010, ΔRMSEA < 0.015). IRT analysis showed high item discrimination parameters (α = 2.01 - 2.95) and well-ordered respnse thresholds. No evidence of differential item functioning (DIF) was found (Δpseudo-R² < 0.02). Criterion-related validity was supported by strong correlations with the T25FW (r = .64, 95% CI [0.57, 0.70]) and the 6MWT (r = -.61, 95% CI [-0.67, -0.53]). Convergent validity was indicated by moderate associations with the EDSS (r = .47, 95% CI [0.37, 0.55]) and the MFIS (r = .45, 95% CI [0.36, 0.54]), while discriminant validity was confirmed by a weak association with the PHQ-9 (r = .28, 95% CI [0.17, 0.38]). CONCLUSION: The Chinese version of the MSWS-12 is a psychometrically sound, culturally valid tool for assessing ambulatory disability in Mandarin-speaking individuals with MS. Its demonstrated reliability, validity, and measurement invariance support its application in clinical practice and cross-cultural research. - The Buffering Role of Self-compassion in the Association Between Loneliness with Depressive Symptoms: A Cross-Sectional Survey Study Among Older Adults Living in Residential Care Homes During COVID-19

Background Insomnia is a highly prevalent sleep disorder frequently comorbid with mental health conditions in nurses. Despite the effectiveness of evidence-based cognitive behavioral therapy for insomnia (CBT-I), there is a critical need for alternative approaches. This study investigated whether internet-delivered mindfulness-based stress reduction (IMBSR) for insomnia could be an alternative to internet-delivered CBT-I (ICBT-I). Objective The hypothesis was that the IMBSR would be noninferior to the ICBT-I in reducing the severity of insomnia among nurses with insomnia. Additionally, it was expected that ICBT-I would produce a greater reduction in the severity of insomnia and depression than IMBSR. Method Among 240 screened nurses, 134 with insomnia were randomly allocated (IMBSR, n = 67; ICBT-I, n = 67). The assessment protocol comprised clinical interviews and self-reported outcome measures, including the Insomnia Severity Index (ISI), Patient Health Questionnaire-9 (PHQ-9), the 15-item Five Facet Mindfulness Questionnaire (FFMQ), and the Client Satisfaction Questionnaire (CSQ-I). Results The retention rate was 55% with 77.6% (n = 104) of participants completing the study. At post-intervention, the noninferiority analysis of the ISI score showed that the upper limit of the 95% confidence interval was 4.88 (P = 0.46), surpassing the pre-specified noninferiority margin of 4 points. Analysis of covariance revealed that the ICBT-I group had significantly lower ISI (Cohen’s d = 1.37) and PHQ-9 (Cohen’s d = 0.71) scores than did the IMBSR group. In contrast, the IMBSR group showed a statistically significant increase in the FFMQ-15 score (Cohen’s d = 0.67). Within-group differences showed that both the IMBSR and ICBT-I were effective at reducing insomnia severity and depression severity and improving mindfulness. Conclusion Overall, nurses demonstrated high levels of satisfaction and adherence to both interventions. The IMBSR significantly reduced insomnia severity and depression, but the findings of this study do not provide strong evidence that the IMBSR is at least as effective as the ICBT-I in reducing insomnia symptoms among nurses with insomnia. The ICBT-I was found to be significantly superior to the IMBSR in reducing insomnia severity, making it a recommended treatment option for nurses with insomnia. - Self-Compassion Moderates the Association Between Body Dissatisfaction and Suicidal Ideation in Adolescents: A Cross-Sectional Study

Identifying risk and protective factors for suicidal ideation during adolescence is essential for suicide prevention. One potential risk factor is body dissatisfaction which appears to peak during adolescence. The present study investigated the self-compassion buffering effects in the relationship between body dissatisfaction and suicidal ideation. A convenience sample comprising 580 adolescents (mean age 16.35 years; SD = .87; range 14–18 years) was recruited from public schools. The results indicated a strong positive association between body dissatisfaction and suicidal ideation (Cohen’s f2 = .25). The association was significantly moderated by the self-compassion (β = − .16, SE = .04, p = .01, t = 2.4.34, .95% CI [− .16, − .01]). Structural equation modeling analysis showed that the lack of self-kindness was associated with a moderate suicidal ideation level (Cohen’s f2 = .14). Also, higher levels of self-judgment predicted suicidal ideation with a moderate to large effect size (Cohen’s f2 = .28). The findings suggest that therapeutic programs designed to develop self-compassion should be implemented to reduce the risk of suicidal ideation among adolescents with body dissatisfaction. The findings empirically show that a higher degree of self-judgment is strongly associated with suicidal thoughts among adolescents, which must be systematically addressed in clinical studies on suicidal risk. - Psychometric Validation of the Indonesian Version of the Fear of COVID-19 Scale: Personality Traits Predict the Fear of COVID-19

The coronavirus disease-2019 (COVID-19) pandemic is a global health crisis that has generated fear and negative psychological consequences. The present study evaluated the validity and factor structure of Fear of COVID-19 Scale (FCV-19S) among a sample from the general Indonesian population. The English version of the FCV-19S was translated and back-translated into Indonesian language, followed by a pilot study. Using convenience sampling method, a total of 728 participants completed an online survey distributed on various social media platforms. The survey included the FCV-19S, personality traits (neuroticism and extraversion), Positive and Negative Affect Scale (PANAS), Generalized Anxiety Disorder Scale (GAD-7), and the nine-item Patient Health Questionnaire (PHQ-9). The Indonesian FCV-19S had very good internal consistency (Cronbach’s alpha and McDonald’s omega) and composite reliability (alpha = 0.88, omega = .86, composite reliability = .87). Maximum likelihood confirmatory factor analysis (CFA) was conducted to test construct validity (χ2/df = 2.51, CFI = .984, SRMR = .028, PCLOSE = .15 > .05, RMSEA = .06, 90% CI [.03, .09]). As for criterion-related validity, the FCV-19S score positively correlated with the score on PHQ-9, GAD-7, negative affect, and neuroticism and negatively correlated with extraversion. Negative affect was identified as the most important predictor of the fear of COVID-19. Personality traits also predicted the fear of COVID-19. The findings provide evidence that the FCV-19S is a reliable and valid instrument for assessing fear generated by COVID-19 among a healthy Indonesian-speaking population. - Psychometric evaluation of the Russian version of the Gaming Disorder Scale for Adolescents

Problematic gaming has become an emerging global health issue. Formal recognition of gaming disorder in the ICD-11 is a new opportunity for the discipline to conduct further investigation concerning the psychological consequences of problematic gaming. The present study investigated the psychometric properties and construct structure of the recently developed Gaming Disorder for Scale for Adolescents (GADIS-A), a multi-dimensional instrument that screens for gaming disorder symptoms, among Russian adolescent gamers. The sample comprised 933 adolescent gamers (547 boys and 386 girls) recruited via a web-based platform, using a multistage sampling method. Analysis showed the GADIS-A had very good internal consistency (Cronbach’s alpha coefficient = .891; Composite reliability = .89) and adequate test–retest reliability after two weeks (intraclass coefficient =0.68 with 95% CI [0.61, 0.77]. Exploratory structural equation modeling (ESEM) showed the data fitted well. Measurement invariance testing indicated the GADIS-A was invariant by gender and gaming medium (online vs. offline). As for criterion-related validity, high scores on the GADIS-A positively correlated with scales assessing depression, anxiety, impulsivity, and difficulties in emotion regulation, and negatively correlated with social connectedness and life satisfaction. Using latent profile analysis, four groups of gamers were identified, and problematic gaming was associated with greater mental health problems. The findings indicated that psychological comorbidity (e.g., depression and anxiety) was more prevalent among gamers with higher risk of GD. The findings indicate that GADIS-A is a reliable and valid instrument to assess the symptoms and severity of gaming disorder among Russian adolescents.

Background Insomnia and poor sleep quality are highly prevalent conditions related to coronavirus disease 2019 (COVID-19) complications among clinical nurses. Although cognitive behavioral therapy for insomnia (CBT-I) is a first-line treatment, CBT-I suffers from several major drawbacks. This study investigates whether the application of the internet-delivered mindfulness-based stress reduction (iMBSR) intervention will produce effects that are non-inferior to the internet-delivered CBT-I (iCBT-I) intervention in reducing the severity of insomnia in clinical nurses with insomnia at the end of the study. Methods This study protocol presents an internet-delivered, parallel-groups, assessor-blinded, two-arm, non-inferiority randomized controlled trial. The primary outcome is sleep quality, assessed by the Insomnia Severity Index. Secondary outcomes include depression, dysfunctional beliefs, five facets of mindfulness, and client satisfaction. Conclusion It is expected that this study may address several gaps in the literature. The non-inferiority study design is a novel approach to evaluating whether a standardized, complementary treatment (i.e., MBSR) is as practical as a gold standard treatment rather than its potential benefits. This approach may lead to expanded evidence-based practice and improve patient access to effective treatments. Trial registration Trial registration number: ISRCTN36198096.

Background Research predominantly suggests that nurses are at high risk of developing psychopathology. The empirical data show that the occurrence rate of problem-related sleep quality among clinical nurses is high. Therefore, this study was conducted to address the lack of information on the relationship between the coronavirus disease 2019 (COVID-19) pandemic and insomnia. Methods A convenience sample of nurses (n = 680) completed an online survey that included the Insomnia severity index, the COVID-19-related psychological distress scale, the general health questionnaire, neuroticism, dysfunctional beliefs, attitudes about sleep scale, and difficulties in emotion regulation scale. Results The results showed that 35.8% (n = 253) of nurses were classified as individuals with moderate to severe clinical insomnia. The results showed that the psychological distress generated by COVID-19 predicted insomnia (β = .47, SE = 0.02, P < .001, t = 13.27, 95% CI 0.31–0.46). Additionally, the association is mediated by psychopathology vulnerabilities, emotion dysregulation, dysfunctional beliefs about sleep, and neuroticism. Moreover, female nurses exhibited higher levels of insomnia (Cohen’s d = .37), neuroticism (Cohen’s d = 30), psychopathology vulnerability (Cohen’s d = .26), and COVID-19-related psychological distress (Cohen’s d = .23). Conclusion The present study’s findings help to explain how pandemic consequences can be associated with insomnia. Additionally, the findings make a significant contribution to better understanding the role of neuroticism, emotion dysregulation, beliefs, and psychopathology vulnerability in the development of insomnia among nurses. The findings suggest the potential influence of cognitive behavioral therapy for insomnia (CBT-I) and transdiagnostic integrated therapies that could be incorporated into therapeutic programs designed to develop as a way of inhibiting or preventing insomnia among clinical nurses. - The role of healthy emotionality in the relationship between fear of COVID-19 and mental health problems: a cross-sectional study
