Abstract Introduction: The IRES -3 questionnaire (Indicators of rehabilitation status, version 3) was developed to evaluate the rehabilitation effect in patients with psychosomatic, cardiac, orthopedic, oncologic, neurologic, gastroenterological and other disorders. Aim: The aim of the present study was to validate the Bulgarian version of IRES-3 and assess its reliability and internal consistency. Materials and methods: Validation of the IRES-3 questionnaire was carried out at the Specialized Rehabilitation Hospital, the National Complex PLtd, the Hisar branch. The study included 46 patients: 14 males (30.43%) and 32 females (69.57%). Patients’ age ranged between 43 and 75 years (mean age 63.52 ± 1.27). All participants got preliminary instructions and after that, within a period of one week, they completed the questionnaire two times. To evaluate IRES-3 reliability we used the split-half-reliability model and calculated the Spearman-Brown coefficients (rsb) for each of the scales. Internal consistency was estimated using Cronbach’s alpha coefficient. We used the mean value of the inter-item correlation coefficients as well. Results: The high values of rsb and Cronbach’s coefficient alpha as well as the low values of the inter-item correlation coefficient which were obtained in our study demonstrate that the questionnaire under investigation is of high reliability and internal consistency. Our results are very similar to the results of the original German questionnaire which have been reported in literature. Conclusion: The Bulgarian version of the IRES-3 questionnaire shows high reliability and cross-cultural validity and can be applied widely for evaluation of the effect of rehabilitation.

Background and aim The Work Osteoarthritis or joint-Replacement Questionnaire (WORQ) is a new assessment tool developed in the Netherlands. It needs translation and cross-cultural adaptation for use in each country. The aim of this study was to translate the Work Osteoarthritis or joint-Replacement Questionnaire into Korean and to verify its reliability and validity. Methods To evaluate the clinimetric quality of the Korean-WORQ, we performed tests for internal consistency (Cronbach's alpha), reliability (intra-class correlation coefficients) and concurrent validity (Spearman's correlation coefficient). Factor analysis was carried out to identify the principal components of the questionnaire. Findings Both the internal consistency and intra-class correlation coefficients showed the reliability of the Korean-WORQ to be excellent. The Korean-WORQ had a strong positive correlation with the Western Ontario and McMaster Universities Osteoarthritis Index and three components were extracted in factor analysis. Conclusions Based on these results, the Korean-WORQ seems to be a suitable questionnaire for assessing the disability levels of patients with knee injuries.

Oral Impacts

The study was conducted to develop and provide initial validation results for an Indonesian version of the Child-Oral Impacts on Daily Performances measure among children aged 12-15 years in Jakarta. The Child-OIDP followed an established process of cross cultural adaptation. The face and content validity, internal consistency reliability, and discriminant validity of the Indonesian version of the Child-OIDP were assessed by evaluating its psychometric properties. This was accomplished through a cross-sectional study of 502 participants using a random sampling method to select 6 of 287 schools among all public junior high schools in Jakarta. Clinical assesment was done according to the Indonesian version of the Child-OIDP. Result of this study confirmed that the cross-cultural adaptation process of  the Indonesian Child-OIDP was well established. All the inter-item correlation coefficients among the eight items of Child-OIDP ranged from 0.12 to 0.41. The corrected item-total correlation coefficients ranged from 0.37 to 0.51. The Cronbach’s alpha coefficient was 0.74. The measure was able to discriminate between different clinical groups in terms of pulpal involvement, ulceration, fistula, and abscess (PUFA), gingival index (GI), and plaque index (PI). Overall, 64.9% of the participants reported at least one oral impact in the past 3 months. The Indonesian version of the Child-OIDP demonstrated excellent internal consistency reliability and was well able to discriminate between different clinical groups among children aged 12-15 years in Jakarta.

The Relationship

Air pollution has been deteriorated seriously in Shanghai as a result of urbanization and modernization. Visibility reduction is the most apparent symptom of air pollution. This paper aims to describe the characteristics of visibility and air pollutants in Shanghai, and to investigate the relationship between them. Visibility in Shanghai was higher in summer and lower in winter. The mean value of visibility during 2006-2010 was 17.8km. Air pollution in Shanghai was also serious. In 2010, Shanghai got the relative better air quality compared with the former four years. Air pollutants and visibility were negatively correlated. SO2 and NO2 had higher correlation coefficients with visibility than PM10. This suggested that the visibility in Shanghai was mainly due to secondary pollutants.

Introduction: The Endometriosis Health Profile-30 is a disease-specific patient-reported outcome measure of health-related quality of life. Cross-cultural validation of the Endometriosis Health Profile-30 has been performed for several translated versions. The aim of this study was to evaluate the measurement properties of a Norwegian version Endometriosis Health Profile-30. Methods: This study was designed as a cross-sectional anonymous postal questionnaire study. A total of 157 women with endometriosis were included during a period from 2012 to 2013. Women aged 18–45 years were recruited from the Norwegian Endometriosis Association. Principal components analysis with varimax rotation was used to assess construct validity. Short Form-36 was used to determine convergent validity. Cronbach’s alpha was used to measure internal consistency. Intraclass correlation coefficients and paired t-tests were used to evaluate test–retest reliability. Floor and ceiling effects were estimated. Results: Factor analysis resulted in a three and five-factor model for the core and modular questionnaire, respectively. Factor analysis could not support construct validity of the scales self-image and treatment. The Norwegian version Endometriosis Health Profile-30 demonstrated acceptable internal consistency and test–retest reliability, except for the scale relationship with children. Floor effects were observed for the scales self-image (20.1%), work life (33.9%), relationship with children (34.2%), and medical profession (20.5%). Conclusion: The construct self-image does not seem to be measured appropriately by the Norwegian version Endometriosis Health Profile-30, suggesting a lack of cross-cultural validity of the Endometriosis Health Profile-30. With multinational studies increasing, adequate translation, cross-cultural adaptation, and cross-cultural validation of instruments are essential to ensure equivalence in languages and cultures other than the original.

The Mean

An impedance plethysmographic method for measuring systolic and diastolic blood pressures in small infants using standard electro-cardiogram recorders has been studied. The overall 95% confidence limit of the mean of five estimations was found to be ±3.74 mm Hg for the systolic and ±3.72 mm Hg for the diastolic value. Comparing this method with intra-arterial measurements gave correlation coefficients (r) of 0.95 (bias 10.09 mm Hg) for systolic pressure and 0.89 (Bias 10.09 mm Hg) for diastolic pressure. Values for the comparison with auscultation were 0.98 (bias 19.29 mm Hg) systolic and 0.86 (bias 10.17 mm Hg) diastolic, and for the comparison of the arithmetic mean value with the flush method 0.84 (bias 30.17 mm Hg). These results reveal a good correlation with the intra-arterial measurements and indicate that this technique can be used for the periodic or continuous blood pressure monitoring of infants.

Abstract Background A valid measure to describe the most important needs and concerns of people with life-threatening illnesses is missing in Cyprus. Our aim was to adapt and test the cross-cultural validity and responsiveness of the Integrated Palliative care Outcome Scale (IPOS) in a cohort of Turkish speaking cancer patients. Methods The IPOS (English) patient-reported measure was translated into Turkish following published guidelines including, 2 independent forward, 2 independent blind backward translations, expert panel review by 7 members and field testing with 11 cognitive interviews (5 patients and 6 specialists) and final approval of the copyright holder. Consecutive cancer patients (n = 234) seen by the community palliative care services were recruited from Help Those with Cancer Society (KHYD); of those 82 were followed-up. The instrument was administered by personal interview. Confirmatory Factor Analysis was used to validate the factor structure of Turkish IPOS. Internal consistency reliability of the subscales was evaluated by Cronbach’s alpha and Intraclass Correlation Coefficient respectively. Validity was assessed by calculating Pearson’s correlation coefficient (r) between Turkish IPOS scores and Turkish version of EQ-5D-3L - a validated generic measure of health status developed by the EuroQol Group. Results Turkish IPOS is conceptually and semantically equivalent to the English version and linguistically valid. The CFA was inconclusive for the three factor structure due to low sample size, as the SRMR and CFI tests only approached the defined minimums warranting further investigation. There were low levels of missing values, and no ceiling or floor effects. The Physical (α = 0.91) and the Social and Quality of Care Issues (α = 0.75) sub-scales showed good internal consistencies, however Emotional sub-scale showed poor internal consistency (α = 0.64). The reliability of the Physical (ICC = 0.51, 0.45–0.56 95% CI) and Social Quality of Care Issues (ICC = 0.50, 0.42–0.57 95% CI) were moderate. Poor internal consistency (α =0.64) and reliability (ICC = 0.31, 0.24–0.39, 95% CI) was obtained for Emotional Subscale. Construct validity was evidenced through significant correlations in the predicted directions and strength with EQ-5D. Turkish IPOS showed higher needs and concerns in participants at more advanced stages than those at earlier stages of cancer. The standardized response mean (SRM) of − 0.94 suggested large internal responsiveness to clinical change. Conclusion Turkish IPOS is a clear, relevant, acceptable measure and responsive to the needs and concerns of cancer patients, observing regional differences, it may have implications for use in other Turkish speaking communities. Future studies are needed to clarify the factor structure, assess its external responsiveness and to improve the properties of its Emotional subscale.

Purpose Indices from 3-D ultrasound may have a role in developmental dysplasia of the hip (DDH) assessment, but require a way to determine spatial orientation relative to body axes. The lateral iliac wall angle is a potentially suitable reference axis in 3-D ultrasound. We sought to quantify normal values and variations of the infant iliac wall angle on radiography, and compare with computed tomography (CT). Methods Acetabular and lateral iliac angles were measured on frontal pelvic radiographs of 200 patients (400 hips, 183 with DDH) and coronal CT of 20 patients (40 hips) aged 0-12 months. Relationships among morphologic indices and demographics were assessed using linear regression, Welch's t-test, Pearson's correlation coefficient (r) and coefficients of variance (CoV). Reliability was assessed using intra-class correlation coefficients (ICC). Results The radiographic iliac angle averaged 53.0° ± 7.7° (mean ± standard deviation; 95% CI, 38°-68°) in DDH vs. 56.2° ± 6.7° (95% CI, 43°-69°) in normal hips (p<0.001), correlated weakly with age (r = 0.25), and showed no inter-sex differences (p = 0.79). Inter-reader and intra-reader reliability were ICC = 0.946 and 0.965. CT iliac angle had mean difference 5.8° ± 6.2° (p<0.01), CoV = 10% and r = 0.68 vs. corresponding radiographs. Conclusions The radiographic infant lateral iliac wall angle has mean value 53-56° in dysplastic and normal hips with consistent range of variation approximately ±15°, was measured with high reliability, does not differ by sex, and is only slightly lower in the youngest infants. The iliac wall angle is an unbiased reference axis that may be suitable to establish general spatial orientation of 3-D hip ultrasound images.

BACKGROUND Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. OBJECTIVE The main objective of this study was to validate the French version of the WART. METHODS Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers’ sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). RESULTS Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI −9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. CONCLUSIONS The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

Background and Objective: Psycho-education of carers is a part of good mental health practice. Our objective was to translate and validate the English questionnaire “Assessment of Psycho-Education of Carers” (APEC) into Urdu (APEC-U), for use in Pakistan. Methods: Following development and validation of APEC, it was translated into Urdu after consultation with experts and translators. After pretesting, one hundred and twenty bilingual male 67(55.8%) and female 53(44.2%) primary carers, who could understand both Urdu and English, and were carers for more than three months, were asked to fill in the self reporting Urdu questionnaire at the Fatima Memorial Hospital Psychiatry Out-Patient Department. The data were collected over a period of three months from September, 2018 to November, 2018. Main outcome measures: Responses were analyzed for internal consistency, reliability, Intraclass correlation coefficients and kappa statistics. Results: APEC-U was understandable and capable of assessing psycho-education in Urdu. High internal consistency was demonstrated on the full scale as 0.859. Degree of agreement (<0.001) between the Urdu and the originally developed English version was evaluated by Cohen’s Kappa, and a high degree of agreement was demonstrated. Conclusion: The Urdu questionnaire can adequately assess psycho-education of carers in psychiatric settings. doi: https://doi.org/10.12669/pjms.35.4.661 How to cite this:Haider II, Tiwana F, Zohra N, Khaleeq Ur Rehman.
