BACKGROUND:French versions of the Chronic Respiratory Questionnaire (CRQ) and the St George's Respiratory Questionnaire (SGRQ) have largely been used in Canada, although the process by which they were translated remains unknown and the psychometric properties of these translated versions have not been assessed in a properly designed study.OBJECTIVE:To translate and evaluate the psychometric properties of the French-Canadian versions of the CRQ and the SGRQ.METHODS:The questionnaires were translated according to standardized guidelines for cross-cultural adaptation. Measurements were made at baseline and again after two weeks in 27 chronic obstructive pulomonary disease (COPD) patients known to have stable disease. Measurements were also taken pre- and post-treatment in patients with acute exacerbation of COPD (33 patients) or in pulmonary rehabilitation (32 patients).RESULTS:The CRQ showed high test-retest reliability (the majority above 0.70), although it was slightly lower for the dyspnea dimension (0.58 to 0.65). The SGRQ also showed high test-retest reliability (above 0.80), although it was lower for the symptoms dimension (0.54 to 0.58). The internal consistency reliability coefficients ranged from 0.73 to 0.90 for the CRQ and above 0.80 for the SGRQ, except for the symptoms dimension. The Pearson's correlation coefficients were low (less than 0.30) between most of the translated questionnaire dimension scores and forced expiratory volume in 1 s, 6 min walking test and dyspnea measures. The correlation was generally high (greater than 0.50) between the two questionnaires and the 36-item short form health survey, and for those domains that measured the same construct. The changes in the total and subscale scores of the CRQ and the SGRQ (except for the symptoms domain) were all largely above the variability of the score in the stable disease group.CONCLUSION:The present study confirms that the French-Canadian translated versions of the CRQ and the SGRQ perform well with respect to their psychometric properties. They are both suitable for their intended purpose, ie, to detect change in health status in patients with COPD when assessing if a treatment is beneficial. However, the symptoms domain of the SGRQ cannot be used to assess acute change with respect to a given therapy.

Abstract Background The short form of the Stroke Impact Scale (SF-SIS) consists of eight questions and provides an overall index of health-related quality of life after stroke. The goal of the study was the evaluation of construct validity, reliability and responsiveness of the SF-SIS for the use in German-speaking stroke patients in rehabilitation. Methods The SF-SIS, the Stroke Impact Scale 2.0 (SIS 2.0), EQ-5D-5L, National Institutes of Health Stroke Scale (NIHSS) and de Morton Mobility Index were assessed in 150 inpatients after stroke, with a second measurement two weeks later for the analyses of responsiveness. In 55 participants, the test–retest-reliability was assessed one week after the first measurement. The study was designed following the recommendations of the COSMIN initiative. Results The correlations of the SF-SIS with the SIS 2.0 (ρ = 0.90), as well as the EQ-5D-5L (ρ = 0.79) were high, as expected. There was adequate discriminatory ability of the SF-SIS index between patients who were less and more severely affected by stroke, as assessed by the NIHSS. Exploratory factor analysis indicated a two-factor structure of the SF-SIS explaining 59.9% of the total variance, providing better model fit in the confirmatory factor analysis than the one-factorial structure. Analyses of test–retest-reliability showed an intraclass correlation coefficient of 0.88 (95% CI 0.75–0.94). Hypotheses concerning responsiveness were not confirmed due to lower correlations between the assessments change scores. Conclusion Results of this analysis of the SF-SIS’s psychometric properties are matching with the validity analysis of the English original version, confirming the high correlations with the Stroke Impact Scale and the EQ-5D-5L. Examination of structural validity did not confirm the presumed unidimensionality of the scale and found evidence of an underlying two-factor solution with a physical and cognitive domain. Sufficient test–retest reliability and internal consistency were found. In addition, this study provides first results for the responsiveness of the German version. Trial registration The study was registered at the German Clinical Trials Register. Trial registration number: DRKS00011933, date of registration: 07.04.2017

Objectives: Views on who bears how much responsibility for supporting individuals with mental health problems may vary across stakeholders (patients, families, clinicians) and cultures. Perceptions about responsibility may influence the extent to which stakeholders get involved in treatment. Our objective was to report on the development, psychometric properties and usability of a first-ever tool of this construct. Methods: We created a visual weighting disk called ‘ShareDisk’, measuring perceived extent of responsibility for supporting persons with mental health problems. It was administered (twice, 2 weeks apart) to patients, family members and clinicians in Chennai, India ( N = 30, 30 and 15, respectively) and Montreal, Canada ( N = 30, 32 and 15, respectively). Feedback regarding its usability was also collected. Results: The English, French and Tamil versions of the ShareDisk demonstrated high test–retest reliability ( rs = .69–.98) and were deemed easy to understand and use. Conclusion: The ShareDisk is a promising measure of a hitherto unmeasured construct that is easily deployable in settings varying in language and literacy levels. Its clinical utility lies in clarifying stakeholder roles. It can help researchers investigate how stakeholders’ roles are perceived and how these perceptions may be shaped by and shape the organization and experience of healthcare across settings.

Oxford Happiness Questionnaire

The Oxford Happiness Questionnaire short-form (Hills & Argyle, 2002) is an 8-item measure of happiness. This study evaluated the internal consistency reliability and test-retest reliability of the Oxford Happiness Questionnaire short-form among 55 Northern Irish undergraduate university students who completed the measure on two occasions separated by two weeks. Internal consistency of the measure was satisfactory at both Time 1 (alpha = .62) and Time 2 (alpha = .58). Stability across the two administrations was satisfactory (r = .69), and there was no significant change between Time 1 (M = 34.5, SD = 5.4) and Time 2 (M = 34.6, SD = 5.2). These data support the internal consistency reliability and short-term test-retest reliability of the Oxford Happiness Questionnaire short-form.

Background: Only 61% of Malawian women exclusively breastfeed to the recommended 6 months. Paternal support is predictive of exclusive breastfeeding, and significantly related to paternal breastfeeding self-efficacy, defined as fathers’ confidence in their ability to assist mothers with breastfeeding. Research Aims: To (1) examine the psychometric properties of the Paternal Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) in Malawian fathers, including internal consistency reliability, test-retest reliability, construct validity using Confirmatory Factor Analysis (CFA), and convergent validity; and (2) assess the relationship between the BSES-SF and paternal demographic and health factors. Methods: A cross-sectional study was conducted at a maternity hospital in Lilongwe, Malawi, and 180 fathers whose partners had delivered a singleton infant were included. Participants completed the Breastfeeding Self-Efficacy Scale and Quality of Life with confirmatory factor analysis performed to assess the construct validity. The internal consistency reliability and test-retest reliability were evaluated using Cronbach’s alpha coefficient and intra-class correlations. Convergent validity was also assessed. Results: A unidimensional factorial structure of the Malawian Paternal BSES-SF was identified using confirmatory factor analysis. The scale had an excellent Cronbach’s alpha of .90 and a test-retest reliability of .93. Participants’ breastfeeding self-efficacy was significantly correlated with the Quality of Life domains of psychological health ( r = .23; p < .01), social relationships ( r = .28; p < .001), and environmental health ( r = .30; p < .001). Participants who were older, married, and with ≥ two children had significantly higher breastfeeding self-efficacy and were more confident in their ability to support their partner’s breastfeeding. Conclusion: The Paternal Breastfeeding Self-Efficacy Scale-Short Form was a valid and reliable measure to assess fathers’ confidence in their ability to assist mothers with breastfeeding in Malawi.

Stressor Scale

The lack of a suitable assessment tool may limit optimal stress management and impair the health-related quality of life of patients undergoing hemodialysis. The purpose of the study was to examine latent constructs and psychometric properties of the Vietnamese Hemodialysis Stressor Scale (HSS-V). In total, 180 patients receiving hemodialysis were recruited. Psychometric properties of the HSS-V, including the construct validity, internal consistency, and test–retest reliability, were tested after the instrument translation. The exploratory factor analysis resulted in a 24-item HSS-V with four extracted factors, which explained 58.32% of the total variance. The construct validity was confirmed by significant negative correlations between scores on the HSS-V and Vietnamese-version Short Form-36. The internal consistency (Cronbach’s α = .82-.91) and test–retest reliability (intra-class correlations coefficient = .91-.94) of the 24-item HSS-V were satisfactory. A simple structure and preliminary acceptable psychometric properties of the HSS-V were established and can serve as a basis for further studies.

Background: Construct of Alexithymia is important for understanding psychopathology that its assessment is of high interest as persons with difficulty in processing their emotions (either positive and negative) are more vulnerable to psychopathology problems. Objectives: The current study aimed to determine the psychometric properties of the Perth Alexithymia questionnaire (PAQ), and to describe appropriate measures for the field of clinical psychology and psychiatry. Methods: The Persian version of the PAQ was produced through forward translation, reconciliation, and back translation. The study population was all staff (soldiers) of the army force in Tehran, Iran, in 2018 - 2019. Two hundred and fifty four soldiers were selected by convenience sampling method. The following questionnaires were used to collect data: the PAQ, The Deliberate Self-Harm inventory (DSHI), Borderline Personality scale (STB), Cognitive Flexibility inventory (CFI), and Self-Compassion scale (SCS) short-form. The construct validity of the PAQ was evaluated using confirmatory factor analysis, divergent, and convergent validity. Internal Consistency and test-retest reliability (2 weeks’ interval) were applied to evaluate reliability. Data were analyzed using LISREL (version 8.8) and SSPS (version 22). Results: PAQ and its subscales were found as valid and reliable measures, with good internal consistency and good test-retest reliability. The PAQ showed good internal consistency (Cronbach’s α = 0.91). Concerning the convergent validity, PAQ and its subscales showed a significant positive correlation with self-report measures of DSHI and STB (P < 0.05). However, they were negatively correlated with Self-Compassion scale (SCS) short-form and CFI (P < 0.05), which demonstrated a good divergent validity. Moreover, while the results of this study support the five-factor models of the PAQ (RMSEA = 0.08, NFI = 0.94, CFI= 0.95), the two-factor model does not fit the data. Conclusions: The PAQ showed good validity and reliability and can be useful for evaluating Alexithymia in the army force samples. The PAQ can be considered promising as a measure in Alexithymia-related research and clinical settings.

The purpose of this study was to identify the factor structure of the Child Oral and Motor Proficiency Scale (ChOMPS) and to evaluate the psychometric properties, including internal consistency reliability, test–retest reliability, and construct validity as measured by convergent and known-groups validity. Principal component analysis with varimax rotation conducted on responses from 364 parents of children between 6 months and 7 years of age identified four subscales: complex movement patterns, basic movement patterns, oral-motor coordination, and fundamental oral-motor skills. Acceptable internal consistency reliability (Cronbach’s α = .97) and test–retest reliability ( r = .98) were found. Convergent and known-groups validity were supported by significant associations between the ChOMPS and validation measures, as well as significant differences in the ChOMPS scores between children with and without feeding problems. The ChOMPS is a 63-item parent-report measure of eating, drinking, and related motor skills in children aged 6 months to 7 years with evidence of reliability and validity.

Objective This study aimed to validate the Japanese version of the LupusPRO questionnaire for use with systemic lupus erythematosus patients. Methods Participants were 205 lupus patients recruited from three rheumatology centers in Japan. Demographic data were collected and quality of life was assessed using the LupusPRO and the Short Form Health Survey-12. Disease activity was evaluated by physicians using the Systemic Lupus Erythematosus Activity Index. Some participants completed questionnaires 10–14 days after the first survey. Internal consistency reliability, test-retest reliability, content validity and convergent validity were examined, and confirmatory factor analysis was performed. Results Participants’ mean age was 47.8 ± 13.6 years. Older participants scored lower on physical quality of life and higher on coping than younger participants. The LupusPRO showed satisfactory test-retest reliability ( n = 111). Test-retest reliability was lower for the mental and social aspects of quality of life, indicating fluctuations in quality of life during the two-week interval. Internal consistency reliability was good and convergent validity with the corresponding domains of the Short Form Health Survey-12 was satisfactory. Confirmatory factor analysis showed a good model fit. Conclusion The Japanese LupusPRO is a reliable and valid measure to evaluate treatment interventions for systemic lupus erythematosus.

ABSTRACT Objective The Fugl-Meyer motor scale is a well-validated measure for assessing upper extremity and lower extremity motor functions in people with stroke. The Fugl-Meyer Assessment (FM) motor scale contains numerous items (50), which reduces its clinical usability. The purpose of this study was to develop a short form of the FM for people with stroke using a machine learning methodology (FM-ML) and compare the efficiency (ie, number of items) and psychometric properties of the FM-ML with those of other FM versions, including the original FM, the 37-item FM, and the 12-item FM. Methods This observational study with follow-up used a secondary data analysis. For developing the FM-ML, the random lasso method of ML was used to select the 10 most informative items (in terms of index of importance). Next, the scores of the FM-ML were calculated using an artificial neural network. Finally, the concurrent validity, predictive validity, responsiveness, and test–retest reliability of all FM versions were examined. Results The FM-ML used fewer items (80% fewer than the FM, 73% fewer than the 37-item FM, and 17% fewer than the 12-item FM) to achieve psychometric properties comparable to those of the other FM versions (concurrent validity: Pearson r = 0.95–0.99 vs 0.91–0.97; responsiveness: Pearson r = 0.78–0.91 vs 0.33–0.72; and test–retest reliability: intraclass correlation coefficient = 0.88–0.92 vs 0.93–0.98). Conclusion The findings preliminarily support the efficiency and psychometric properties of the 10-item FM-ML. Impact The FM-ML has potential to substantially improve the efficiency of motor function assessments in patients with stroke.
