Introduction. A careful assessment of dental anxiety is necessary for its management. The Modified Dental Anxiety Scale (MDAS) is one of the most commonly used questionnaires to measure dental anxiety in the world. The reliability and validity of the Japanese version of MDAS have been demonstrated using undergraduates and a few patients with dental anxiety. The aim of the present study was to examine the reliability and validity of the Japanese version of the MDAS using a wide range of age samples in dental clinics. Methods. A total of 275 outpatients (145 men and 130 women; 21–87 years) from two dental clinics participated in the present study. Dental anxiety was assessed using the Japanese version of the MDAS and the Dental Fear Survey (DFS). The psychometric evaluation included exploratory factor analysis, and Cronbach’s α was used to evaluate for internal consistency. Criterion validity was assessed by correlating the MDAS and DFS scores using Spearman’s correlation coefficient. validity was evaluated by examining related factors’ differences in the MDAS score (e.g., sex and negative dental experiences). Results. Six patients (2.2%) reported high levels of dental anxiety (MDAS score ≥ 19). The internal consistency of the MDAS score was high (Cronbach’s α = 0.88). Dental anxiety was significantly higher among women (P=0.007), in patients with previous negative dental experiences (P<0.001), and among those with lower frequencies of dental visits (P<0.001). The MDAS score was significant and related to age (r = 0.48) and the DFS score (r = 0.87). Factor analysis revealed all items measured only one construct. Conclusions. The Japanese version of the MDAS score was found to be a reliable and valid measure of dental anxiety among dental outpatients. It could be useful for the Japanese dental practitioner to measure dental anxiety in a clinical setting.

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.

ObjectivesThe Ocular Surface Disease Index (OSDI) questionnaire is widely used to evaluate subjective symptoms of dry eye disease (DED) as a primary diagnostic criterion. This study aimed to develop a Japanese version of the OSDI (J-OSDI) and assess its reliability and validity.Design and settingHospital-based cross-sectional observational study.ParticipantsA total of 209 patients recruited from the Department of Ophthalmology at Juntendo University Hospital.MethodsWe translated and culturally adapted the OSDI into Japanese. The J-OSDI was then assessed for internal consistency, reliability and validity. We also evaluated the optimal cut-off value to suspect DED using an area under the receiver operating characteristic curve (AUC) analysis.Primary outcome measuresInternal consistency, test–retest reliability and discriminant validity of the J-OSDI as well as the optimal cut-off value to suspect DED.ResultsOf the participants, 152 had DED and 57 did not. The J-OSDI total score showed good internal consistency (Cronbach's alpha=0.884), test–retest reliability (interclass correlation coefficient=0.910) and discriminant validity by known-group comparisons (non-DED, 19.4±16.0; DED, 37.7±22.2; p<0.001). Factor validity was used to confirm three subscales within the J-OSDI according to the original version of the questionnaire. Concurrent validity was assessed by Pearson correlation analysis, and the J-OSDI total score showed a strong positive correlation with the Dry Eye-Related Quality-of-Life Score (γ=0.829). The optimal cut-off value of the J-OSDI total score was 36.3 (AUC=0.744).ConclusionsThe J-OSDI was developed and validated in terms of reliability and validity as an effective tool for DED assessment and monitoring in the Japanese population.

Abstract Background Personal recovery is increasingly recognised as an important outcome measure in mental health services. This study aimed to develop a Japanese version of the Questionnaire about the Process of Recovery (QPR-J) and test its validity and reliability. Methods The study comprised two stages that employed the cross-sectional and prospective cohort designs, respectively. We translated the questionnaire using a standard translation/back-translation method. Convergent validity was examined by calculating Pearson’s correlation coefficients with scores on the Recovery Assessment Scale (RAS) and the Short-Form-8 Health Survey (SF-8). An exploratory factor analysis (EFA) was conducted to examine factorial validity. We used intraclass correlation and Cronbach’s alpha to examine the test-retest and internal consistency reliability of the QPR-J’s 22-item full scale, 17-item intrapersonal and 5-item interpersonal subscales. We conducted an EFA along with a confirmatory factor analysis (CFA). Results Data were obtained from 197 users of mental health services (mean age: 42.0 years; 61.9% female; 49.2% diagnosed with schizophrenia). The QPR-J showed adequate convergent validity, exhibiting significant, positive correlations with the RAS and SF-8 scores. The QPR-J’s full version, subscales, showed excellent test-retest and internal consistency reliability, with the exception of acceptable but relatively low internal consistency reliability for the interpersonal subscale. Based on the results of the CFA and EFA, we adopted the factor structure extracted from the original 2-factor model based on the present CFA. Conclusion The QPR-J is an adequately valid and reliable measure of the process of recovery among Japanese users with mental health services.

The purpose of the present study was to adapt COVID-19 Induced Anxiety Scale (CIAS) and Protective Behaviors towards COVID-19 Scale (PBCS) into Turkish language, and to investigate their psychometric properties. 593 adults participated in the study. Data were collected through CIAS and PBCS as well as The Fear of COVID-19 Scale (FCS). Cronbach alpha (α) and McDonald’s Omega (ω) coefficients were utilized for reliability of the Turkish forms of the scales, and validity of the scales was tested with exploratory factor analysis, confirmatory factor analysis and criterion validity. The analysis showed that α and ω reliability coefficients of both scales were over .70. The results of exploratory and confirmatory factor analyses revealed that CIAS had a single factor structure while PBCS had three dimensions as indicated in original forms of the scales. Significant and positive relationships were also found between the scores obtained from CIAS and PBCS and fear scores. To conclude, Turkish forms of CIAS and PBCS were proved to be valid and reliable tools to measure severity of COVID-19 induced anxiety through CIAS and individuals’ protective behaviors towards COVID-19 through PBCS.

Background & Aim: Self-care in patients with heart failure can improve multiple outcomes and reduce mortality. Measuring self-care requires valid and reliable tools. This study aimed to determine the psychometric properties of the 9-items European Heart Failure Self-Care Behavior Scale. Methods & Materials: The present study is a psychometric evaluation. The original version of the tool was translated from English to Persian using the standard Backward-Forward method. The questionnaire's validity was assessed using face, content, criterion (the Self-Care of Heart Failure Index v.6 as a criterion), and construct validity.  An exploratory factor analysis approach was used to construct validity with a sample of 216 patients with chronic heart failure referred to Dr. Shariati and Imam Khomeini Hospital's heart clinics in Tehran; and Ayatollah Mousavi Hospital in Zanjan. The reliability of the questionnaire was evaluated by internal consistency and stability methods. Results: After the validation process (validity and reliability), all 9 items of the questionnaire were approved and remained. The content validity index of the total content of the questionnaire was calculated to be 0.96. Based on factor analysis, only one factor was confirmed for the questionnaire. The correlation between the present questionnaire and the Self-Care of Heart Failure Index v.6 was positive and significant (p<0.001, r=0.753). Internal consistency (α=0.728) and stability (0.897) of the questionnaire were also confirmed. Conclusion: The European Heart Failure Self-Care Behavior Scale is valid and reliable for measuring Iranian patients' self-care behaviors with heart failure.

Abstract Background Appropriate assessment is essential for the management of chemotherapy-induced peripheral neuropathy (CIPN), an intractable symptom that cannot yet be palliated, which is high on the list of causes of distress for cancer patients. However, objective assessment by medical staff makes it easy to underestimate the symptoms and effects of CIPN in cancer survivors. As a result, divergence from subjective evaluation of cancer survivors is a significant problem. Therefore, there is an urgent need to develop a subjective scale with high accuracy and applicability that reflects the experiences of cancer patients. We developed a comprehensive assessment scale for CIPN in cancer survivors, named the Comprehensive Assessment Scale for Chemotherapy-Induced Peripheral Neuropathy in Survivors of Cancer (CAS-CIPN), and demonstrated its reliability and validity. Methods We developed a questionnaire based on qualitative studies of peripheral neuropathy in Japanese cancer patients and literature review. Twelve cancer experts confirmed the content validity of the questionnaire. A draft version comprising 40 items was finalized by a pilot test on 100 subjects. The participants in the present study were 327 Japanese cancer survivors. Construct validity was determined by factor analysis, and internal validity by confirmation factor analysis and Cronbach’s α. Results Factor analysis showed that the structure consisted of 15 items in four dimensions: “Threatened interference in daily life by negative feelings”, “Impaired hand fine motor skills”, “Confidence in choice of treatment/management,” and “Dysesthesia of the palms and soles.” The CAS-CIPN internal consistency reliability was 0.826, and the reliability coefficient calculated using the Spearman-Brown formula [q = 2r/(1 + r)] was 0.713, confirming high internal consistency and stability. Scores on this scale were strongly correlated with Gynecologic Oncology Group-Neurotoxicity scores (r = 0.714, p < 0.01), confirming its criterion-related validity. Conclusions The CAS-CIPN is an assessment tool with high reliability and validity for the comprehensive evaluation of CIPN in cancer survivors. The CAS-CIPN is simple to use, and can be used by medical professionals for appropriate situational assessment and intervention.

Background: Patient participation in treatment and care is often encouraged and is desirable because of its proven positive impact on treatment, quality of care and patient safety. Aims: To develop an instrument to measure patient participation in health care and to investigate the measurement properties of the Patient Participation Questionnaire (PPQ). Methods: A literature review was conducted to develop a model of patient participation. The PPQ was constructed consisting of 17 items organized into four subscales. Psychometric evaluation of factor structure, convergent construct validity by hypothesis testing and analyses of internal consistency using Cronbach’s alpha were performed on data from a hospitalised mixed group of patients with cardiac disease, pulmonary disease and cancer ( N=378 patients). Results: Confirmatory factor analysis did not show a clear model fit, which is why an exploratory factor analysis was performed, suggesting a different four subscale structure consisting of a total of 16 items. The four subscales were labelled Shared decision power, Adapted and individualized knowledge, Collaboration and Human approach. There were strong ceiling effects on all items. Analysis of convergent construct validity showed a moderate correlation (0.59) between the PPQ and another instrument measuring patient participation. Internal consistency for the total PPQ score was high: 0.89. Conclusion: In a mixed group of patients with cardiac disease, pulmonary disease and cancer, the PPQ showed promising psychometric properties in terms of factor structure, convergent construct validity and internal consistency. The PPQ may be used to shed light on the experience of patient participation and guide quality improvements.

The capacity to direct attention (CDA) is a pivotal facet of cognitive functioning that allows people to focus on trains of thought, complex tasks, and the daily business of life. According to a theoretical framework of directed attentional fatigue (DAF) and restoration, excessive demand for attention depletes CDA, a condition called DAF. Attentional demands are factors such as feelings of loss and worries that require intense or prolonged use of CDA and thus can lead to DAF. The purposes of this study were to determine reliability and validity for an instrument to measure attentional demands, the Attentional Demands Survey (ADS). The ADS was administered to 197 (142 females, 50 males) community-dwelling elderly (ages 65-98 years, M = 77). A factor analysis revealed 4 factors/subscales consistent with theorized domains. Internal consistency for each subscale ranged from .87 to .90 and test-retest reliability was .91. The ADS can be used to explore the relationships among attentional demands, CDA, and interventions to support and restore attentional functioning for elders.

Attitudes Toward War

A measure on attitudes toward war was administered to 125 student participants at a California university to assess psychometric properties for this scale for possible use in current research. A 5-point scale was substituted for the 2-point one originally. Item analysis indicated 23 of 32 items were viable. Using Cronbach reliability coefficient α and factor analysis, the shortened measure had an internal consistency reliability of .85. Factor analysis yielded a 4-factor structure: (1) War is Bad, (2) War is Necessary, (3) Positive Aspects of War, and (4) No Justification. These results indicate this seemingly outdated measure of war attitudes remains useful for current research purposes involving measuring attitudes toward war. However, longitudinal research is necessary.
