Developing a Japanese version of the Injustice Experience Questionnaire-chronic and the contribution of perceived injustice to severity of menstrual pain: a web-based cross-sectional study.

ABSTRACT:

Background

Menstrual pain causes low quality of life among women of reproductive age, and often interferes with daily activities. Perceived injustice is a cognition linked to adverse symptoms. The aims of this study were to develop a Japanese version of the Injustice Experience Questionnaire-chronic (IEQ-chr-J), and to examine if perceived injustice is associated with pain intensity and impairment from menstruation.

Methods

We investigated 130 Japanese women (aged 20-45?years) with menstrual pain in the past 3?months using online self-administered questionnaires. We examined the psychometric properties of the IEQ-chr-J including: structural validity; internal consistency; and test-retest reliability (intra-class correlation coefficients; ICC). Concurrent validity was examined by correlations among the IEQ-chr-J, the Pain Catastrophizing Scale (PCS), the Hospital Anxiety and Depression Scale (HADS), a numerical rating scale (NRS) for maximum/average menstrual pain, and the Brief Pain Inventory (BPI) pain interference domain. We used multivariable regression analysis to investigate the association between perceived injustice and severity of menstrual pain, after excluding 10 hormone drug users.

Results

The IEQ-chr-J showed sufficient validity and reliability (Cronbach's ??=?0.96, ICC 0.75, [95% confidence interval (CI): 0.61-0.88]. Pearson's correlation coefficients for the IEQ-chr-J, PCS, HADS anxiety, HADS depression, NRS, and BPI pain interference ranged from 0.27-0.65. The IEQ-chr-J was correlated with impairment due to menstrual pain (ICC 0.36, 95% CI: 0.14-0.58), an independent diagnosis of endometriosis, anxiety, and depression, but not with maximum or average pain intensity.

Conclusions

The IEQ-chr-J has acceptable psychometric properties, and perceived injustice is associated with impairment from menstrual pain.

Project description:BackgroundThere is increasing international interest in clinical practice and research related to mental health in the international sports society. The athlete-specific psychological distress assessment tool that addresses potential mental health needs can help promote early detection and recovery of mental illness, as well as physical illnesses. Currently, little is known about the applicability of the useful assessment tool for Japanese elite athletes. The Athlete Psychological Strain Questionnaire (APSQ) is a brief, effective and reliable screening tool to identify early signs of athlete-specific distress and potential mental health symptoms. We examined the applicability and reliability of a Japanese version of the APSQ (APSQ-J) in a Japanese elite athlete context. Further, we examined the construct validity of the APSQ-J.MethodsWe collected web-based anonymous self-report data from 219 currently competing Japanese professional male rugby players. A two-stage process was conducted to validate the factor structure of the APSQ-J using exploratory factor analysis (EFA) in a randomly partitioned calibration sample and confirmatory factor analysis (CFA) in a separate validation sample. Cronbach's alpha is used to assess internal consistency. Pearson product-moment correlation coefficients were calculated to determine if the APSQ-J was significantly associated with measures of psychological distress and well-being using Kessler-6 (K6) and the WHO-5 Well-Being Index, respectively.ResultsWe identified a one-factor structure for the APSQ-J. Confirmatory factor analysis supports this one-factor model, revealing good model fit indices. The standardized path coefficients for each of the items were β = 0.41-0.83 (p < 0.001). A Cronbach's alpha of 0.84 was obtained for the APSQ-J. The APSQ-J demonstrated significant correlations with the K-6 (r = 0.80, p < 0.001) and WHO-5 (r = -0.58, p < 0.001).ConclusionThe APSQ-J can be an appropriate and psychometrically robust measure for identifying athlete-specific distress in elite athletes in Japan. Widely disseminating and utilizing this scale in Japanese sports society may support athletes' mental health via early detection of symptoms of psychological distress.

Project description:BackgroundHeart failure is a worldwide health problem that significantly affects patients' physical function and health state. The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a disease-specific patient-reported outcome measure commonly used for the assessment of health states of patients with heart failure. This study aimed to evaluate the psychometric properties of the Japanese version of the KCCQ.MethodsUsing pooled data of 141 Japanese patients with chronic heart failure from three clinical trials, the Japanese version of the KCCQ was evaluated for validity and reliability, with a focus on the clinical summary score (CSS) and its component domains. For construct validity, the associations of baseline KCCQ scores with New York Heart Association (NYHA) class and the EuroQol five-dimension, three-level (EQ-5D-3L) scores at baseline were analyzed. For reliability, internal consistency was assessed using Cronbach's α, and test-retest reliability (reproducibility) was assessed among stable patients. Responsiveness to changes in patients' clinical status was assessed by analyzing score changes between two timepoints among patients whose health states improved.ResultsAmong 141 patients (mean age, 73.7 ± 10.9 years), 76.6% were NYHA class II at baseline. For CSS and its component domains (physical limitations, symptom frequency, and symptom severity), baseline scores were all significantly lower in patients with a higher NYHA class (p < 0.001 for all, Jonckheere-Terpstra test). The physical limitations domain and CSS showed a moderate correlation (Spearman's ρ = - 0.40 to - 0.54) with three functional status-related EQ-5D dimensions (mobility, self-care, and usual activities). The Cronbach's standardized α was high (> 0.70) for all KCCQ domain/summary scores. In the test-retest analysis among 58 stable patients, all domain/summary scores minimally changed by 0.3-4.2 points with intraclass correlation coefficients of 0.65-0.84, demonstrating moderate to good reproducibility, except for the symptom stability domain. Among 44 patients with improved health states, all domain/summary scores except for the symptom stability and self-efficacy domains substantially improved from baseline with a medium to large effect size of 0.62-0.88.ConclusionsThe Japanese version of the KCCQ was demonstrated to be a valid and reliable tool for the assessment of symptoms and physical function of Japanese patients with chronic heart failure.
