The rate of spinal dysfunction in overweight and obese subjects was significantly higher than the normal group; the overall score of spinal function was worse than the normal group. Discussion The reliability and validity analyses of this study verified the reliability and scientificity of SSFS in the young healthy population. Body weight had a significant influence on SSFS score, and the performance levels were different for the two sexes. Conclusion The novel Self-Reported Spine Functional Scale (SSFS) has high reliability and validity and is applicable to the self-assessment and maintenance of spinal health and the prevention of related spinal disorders in the young healthy population. Body weight has a significant influence on the SSFS score in healthy young people. Overweight and obese males were found to be more likely to have spinal dysfunction, while underweight males displayed poor cervical flexor muscle strength. Underweight females were found to have better overall spinal function and stronger cervical flexor muscle strength.

ObjectiveThis study aimed to develop a patient safety culture (PSC) scale for maternal and child healthcare (MCH) institutions in China.MethodsA theoretical framework of PSC for MCH institutions was proposed through in-depth interviews with MCH workers and patients and Delphi expert consultations. The reliability and validity of the PSC scale were tested in a cross-sectional survey of 1256 MCH workers from 14 MCH institutions in Zhejiang province of China. The study sample was randomly split into half for exploratory and confirmatory factor analyses, respectively. Test–retest reliability was assessed through a repeated survey of 63 voluntary participants 2 weeks apart.ResultsThe exploratory factor analysis extracted 10 components: patient engagement in patient safety (six items), managerial response to patient safety risks (four items), perceived management support (five items), staff empowerment (four items), staffing and workloads (four items), reporting of adverse events (three items), defensive medical practice (three items), work commitment (three items), training (two items) and transfer and handoff (three items). A good model fit was found in the confirmatory factor analysis: χ2/df=1.822, standardised root mean residual=0.048, root mean square error of approximation=0.038, comparative fit index=0.921, Tucker-Lewis index=0.907. The PSC scale had a Cronbach’s α coefficient of 0.89 (0.59–0.90 for dimensional scales) and a test–retest reliability of 0.81 (0.63–0.87 for dimensional reliability), respectively. The intracluster correlation coefficients confirmed a hierarchical nature of the data: individual health workers nested within MCH institutions.ConclusionThe PSC scale for MCH institutions has acceptable reliability and validity. Further studies are needed to establish benchmarking in a national representative sample through a multilevel modelling approach.

BackgroundThe Anxiety Symptoms Questionnaire (ASQ) is a brief self-report questionnaire which measures frequency and intensity of symptoms and was developed to improve assessment of anxiety symptoms in a clinical setting. We examined the reliability and validity of the ASQ in patients with anxiety disorders and/or depression, non-clinical control subjects and college students.Methods240 outpatients with generalised anxiety disorder, social anxiety disorder, panic disorder or major depressive disorder were administered the ASQ and additional questionnaires measuring depression and anxiety, as were 111 non-clinical control subjects and 487 college students. Factor analysis, Pearson’s correlation coefficients and logistic regression were used to assess reliability and validity. Test–retest reliability of the ASQ was measured using a subset who were re-administered the ASQ after 4 weeks.ResultsFactor analysis revealed measurement of a single dimension by the ASQ. Internal consistency and test–retest reliability were strong. The ASQ total score also significantly distinguished patients with an anxiety disorder from the clinical controls above and beyond the clinician-rated Hamilton Anxiety Scale.ConclusionsThe ASQ is a valid, reliable and effective self-rated measure of anxiety and may be a useful tool for screening and assessing anxiety symptoms in psychiatric as well as college settings.

Purpose. To examine psychometric properties of a Commitment to Physical Activity Scale for Adolescents (CPASA). Design. Two test-retest studies and a prospective study, approved by a university institutional review board, were conducted in midwestern U.S. urban areas. Setting. The first test-retest study occurred in four community centers, the second test-retest study took place in a community school, and the prospective study occurred in eight middle schools. Subjects. To measure commitment at baseline and 1 week later, 51 girls in the first test-retest study completed an original 26-item scale, and 91 in the second test-retest study completed a revised 11-item scale. In the prospective study, 503 girls completed the 11-item scale. Measures. Commitment was measured via the CPASA. After completing the CPASA, girls in the prospective study wore ActiGraph GT3X-plus accelerometers that measured light, moderate, and vigorous physical activity (LMVPA) and moderate to vigorous physical activity (MVPA). Analysis. Internal consistency and test-retest reliability were estimated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to cross-validate the factor structure. Results. For the 11-item CPASA, Cronbach α ranged from .81 to .82, and test-retest reliability was .88. Both EFA and CFA indicated a single factor. The scale was significantly correlated with LMVPA (r = .10) and MVPA (r = .11). Conclusion. The 11-item CPASA demonstrated acceptable reliability and validity with girls.

Objective: This study aimed to translate the Brief-Mindful Self-Care Scale (B-MSCS) into Chinese and validate its reliability and validity among hospice nurses.Methods: A total of 510 hospice nurses were recruited from three provinces in China. The reliability of the translated scale was measured by internal consistency, split-half reliability, and test-retest reliability. The validity of the translated scale was evaluated by expert consultation, exploratory factor analysis, and confirmatory factor analysis.Results: The Cronbach's α value of the Chinese version of B-MSCS was 0.920, and the Cronbach's α value of the dimensions ranged from 0.850 to 0.933. The split-half reliability and test-retest reliability were 0.770 and 0.723, respectively. Furthermore, the content validity index of the scale (S-CVI) was 0.946. The 6-factor structure, supported by the eigenvalues, total variance explained, and scree plot were obtained by using exploratory factor analysis. Moreover, as a result of the confirmatory factor analysis, the model fitting indexes were all in the acceptable range.Conclusion: The Chinese version of B-MSCS had suitable reliability and validity among hospice nurses. The developed scale will evaluate the level of mindful self-care of Chinese hospice nurses, providing an opportunity for development of targeted educational plans. Each item is a direct guide for hospice nurses to develop their mindful self-care practice.

Background Therapists frequently advise the use of activity pacing as a coping strategy to manage long-term conditions (eg, chronic low back pain, chronic widespread pain, chronic fatigue syndrome/myalgic encephalomyelitis). However, activity pacing has not been clearly operationalized, and there is a paucity of empirical evidence regarding pacing. This paucity of evidence may be partly due to the absence of a widely used pacing scale. To address the limitations of existing pacing scales, the 38-item Activity Pacing Questionnaire (APQ-38) was previously developed using the Delphi technique. Objective The aims of this study were: (1) to explore the psychometric properties of the APQ-38, (2) to identify underlying pacing themes, and (3) to assess the reliability and validity of the scale. Design This was a cross-sectional questionnaire study. Methods Three hundred eleven adult patients with chronic pain or fatigue participated, of whom 69 completed the test-retest analysis. Data obtained for the APQ-38 were analyzed using exploratory factor analysis, internal and test-retest reliability, and validity against 2 existing pacing subscales and validated measures of pain, fatigue, anxiety, depression, avoidance, and mental and physical function. Results Following factor analysis, 12 items were removed from the APQ-38, and 5 themes of pacing were identified in the resulting 26-item Activity Pacing Questionnaire (APQ-26): activity adjustment, activity consistency, activity progression, activity planning, and activity acceptance. These themes demonstrated satisfactory internal consistency (Cronbach α=.72–.92), test-retest reliability (intraclass correlation coefficient=.50–.78, P≤.001), and construct validity. Activity adjustment, activity progression, and activity acceptance correlated with worsened symptoms; activity consistency correlated with improved symptoms; and activity planning correlated with both improved and worsened symptoms. Limitations Data were collected from self-report questionnaires only. Conclusions Developed to be widely used across a heterogeneous group of patients with chronic pain or fatigue, the APQ-26 is multifaceted and demonstrates reliability and validity. Further study will explore the effects of pacing on patients' symptoms to guide therapists toward advising pacing themes with empirical benefits.

Abstract Background The Mood and Feelings Questionnaire (MFQ) is a widely used screening tool for child and adolescence depression but has not been validated with young people in Thailand. This study aimed to assess the reliability and validity and to determine the optimal clinical cut-off of the Thai MFQ. Methods The Thai MFQ was evaluated in two parts. In part 1, The MFQ was translated and back translated into the Thai language and piloted on a small number of Thai adolescents. Then 1275 young people aged 12–18 years from three secondary schools in Thailand completed the MFQ and related measures of depression. In part 2, 138 students were invited to take part in a structured diagnostic interview (the Thai translation of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children -Present and Lifetime Version (the K-SADS-PL). Of those, 103 students were interviewed and completed the Thai MFQ a second time to assess test–retest reliability. Receiver Operating Characteristics (ROC) analyses were conducted to evaluate diagnosis accuracy and examine the optimal cut-off score of the Thai MFQ. Results The Thai MFQ had excellent internal consistency (α = 0.92) and good to moderate test–retest reliability in 2-week and 4-week intervals. The Thai MFQ also had good convergent validity with related measures of depression. The ROC analyses demonstrated that the Thai MFQ also had excellent accuracy distinguishing between depressed and non-depressed adolescents [AUC = 0.95, 95% CI [0.92, 0.99]. A total score of 28 on the Thai MFQ was the optimal cut-off score (sensitivity was 0.97 and specificity was 0.83). Discussion The Thai MFQ demonstrated excellent psychometric properties and accurately distinguished between depressed and non-depressed adolescents. It is appropriate to use as a screening measure to identify adolescents with depression in community settings in Thailand.

Computer-based neuropsychological assessments have many advantages over traditional neuropsychological assessments. However, limited data are available on the validity and reliability of computer-based assessments. The purpose of this study was to examine the reliability and validity of computer-based dementia assessment contents (Co-Wis). This study recruited 113 participants from Yeungnam University Medical Center in Daegu from June 2019 to December 2019 and received ethical approval. Participants were evaluated using standard and objective dementia cognitive test tools such as the Korean version of the Mini-Mental State Examination (K-MMSE), the Clinical Dementia Rating Scale (CDR), and the Standardized Seoul Neuropsychological Screening Battery-II (SNSB-II). To verify the effectiveness of Co-Wis, the concurrent validity, test–retest reliability (Pearson’s correlation coefficients), construct validity (Factor analysis), and signal detection analysis (ROC curve) were used. In most of the Co-Wis subtests, the concurrent validity and test–retest reliability showed statistically significant correlations (p < 0.05, p < 0.01). The factor analysis showed that Co-Wis assessed the most major cognitive areas (Tucker–Lewis Index (TLI) = 0.876, Comparative Fit Index (CFI) = 0.897, RMSEA = 0.88). Thus, Co-Wis appears clinically applicable and with high reliability and validity. In the future, we should develop tests to evaluate both standard data and big data-based machine learning.

Objective Somatic symptoms in psychiatry include underlying depression, anxiety, or other psychiatric disorders. This study aimed to conduct a validation study of a Korean version of the Somatic Symptom Scale-8 (K-SSS-8), and to utilize the K-SSS-8 effectively in clinical settings.Methods For reliabilty, test-retest reliability and internal consistency were analyzed. For construct validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. Known-group validity was verified, Jonckheere-Terpstra test (J-T statistic) were used.Results Maternal Cronbach’s alpha was 0.85 and r value of test-retest reliability was 0.777. In the EFA, 2-, 3- and 4-factor model showed cumulative percentile for variance of 60% or more. In the CFA, the 3-factor model was found to be the most appropriated and simplest (χ<sup>2</sup>=10.992, df=17, CFI=1.000, TLI=1.022, RMSEA=0.000). The verifying the difference in K-SSS-8 also showed significant difference. (J-T statistic=-2.510, p<0.05).Conclusion K-SSS-8 can be useful for exploring symptoms such as panic symptoms, physical pain, and physiological symptoms experienced by patients in a short time. In addition, the K-SSS-8 is expected to be very useful for determining the current severity by using the severity categories and for establish additionally required assessment plans for depression and anxiety symptoms.

Abstract Objective Shame contains external and internal aspects. However, a Japanese language scale for simultaneously assessing both aspects of shame has not been developed to date. This study aimed to standardize the Japanese version of the External and Internal Shame Scale (EISS-J). An online survey was conducted among university students (N = 203) at six universities in Japan (Study 1). A retest questionnaire was sent to the participants by email three weeks after the first survey (Study 2). Study 1 examined the internal consistency, factor structure, and criterion-related validity of the EISS-J, while Study 2 examined its test-retest reliability. Moreover, an additional study was conducted to examine the criterion-related validity of the scale. Results Study 1 demonstrated the high internal consistency of the EISS-J. Moreover, confirmatory factor analysis indicated a two-factor model: external and internal shame. However, exploratory factor analysis indicated a three-factor structure. Study 2 confirmed the test-retest reliability of the scale. Furthermore, both studies indicated correlations between the EISS-J and fear of compassion, anger, humiliation, depression, anxiety, and stress. In addition, the study established the criterion-related validity of the scale. These results confirmed adequate reliability and validity of the EISS-J.
