Psychometric evaluation of the shortened version of the Functional Difficulties Questionnaire to assess thoracic physical function

Objective: The aim of this study was to investigate the psychometric properties of the shortened version of the Functional Difficulties Questionnaire (FDQ). Design: This is a multisite observational study. Setting: The study was conducted in four tertiary care hospitals in Australia. Subjects: A total of 225 participants, following cardiac surgery, were involved in the study. Intervention: Participants completed the original 13-item FDQ and other measures of physical function, pain and health-related quality of life. Method: Item reduction was utilized to develop the shortened version. Reliability was evaluated using intraclass correlation coefficients (ICCs), the smallest detectable change and Bland–Altman plots. The validity and responsiveness were evaluated using correlation. Anchor and distribution-based calculation was used to calculate the minimal clinical important difference (MCID). Results: Item reduction resulted in the creation of a 10-item shortened version of the questionnaire (FDQ-s). Within the cohort of cardiac surgery patient, the mean (SD) for the FDQ-s was 38.7 (19.61) at baseline; 15.5 (14.01) at four weeks and 7.9 (12.01) at three months. Validity: excellent internal consistency (Cronbach’s α > 0.90) and fair-to-excellent construct validity (>0.4). Reliability: internal consistency was excellent (Cronbach’s α > 0.8). The FDQ-s had excellent test–retest reliability (ICC = 0.89–0.92). Strong responsiveness overtime was demonstrated with large effect sizes (Cohen’s d > 1.0). The MCID of the FDQ-s was calculated between 4 and 10 out of 100 (in cm). Conclusion: The FDQ-s demonstrated robust psychometric properties as a measurement tool of physical function of the thoracic region following cardiac surgery.

Abstract Objective: To produce a transcultural adaptation of the Thirst Distress Scale (TDS) into Brazilian Portuguese and analyze the scale’s psychometric properties for patients on hemodialysis (HD). Methods: The original scale was translated, back translated, and discussed with psychometric assessment experts. The final version was tested with 126 patients on HD and retested with 70 individuals from the original patient population. Cronbach’s alpha was used to measure the scale’s internal consistency. Reliability of thirst intensity evaluated via the visual analogue scale (VAS) was tested with Kappa statistic and the Bland-Altman plot. Reproducibility was assessed based on the intraclass correlation coefficient (ICC). Results: The wording of three items and the verb tenses of six had to be adjusted in the final version of the Brazilian Portuguese TDS. Comprehension of the scale by patients on HD was good, the scale’s internal consistency was satisfactory (0.84; p<0.001), agreement with a visual analogue scale (VAS) was moderate (kappa=0.44; p<0.001), and reproducibility neared perfection (ICC=0.87; p<0.001). Conclusion: Our results showed that the Brazilian Portuguese version of the scale might be used reliably. The Brazilian Portuguese version of the TDS is a practical, affordable, accessible and well-accepted tool that has a lot to offer for the management of patients with HD.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.

ObjectiveEven though continuity is essential after discharge, there is a lack of reliable questionnaires to measure and assess patients’ perceptions of continuity of care. The Patient Continuity of Care Questionnaire (PCCQ) addresses the period before and after discharge from hospital. However, previous studies show that the factor structure needs to be confirmed and validated in larger samples, and the aim of this study was to evaluate the psychometric properties of the PCCQ with focus on factor structure, internal consistency and stability.DesignA psychometric evaluation study. The questionnaire was translated into Swedish using a forward–backward technique and culturally adapted through cognitive interviews (n=12) and reviewed by researchers (n=8).SettingData were collected in four healthcare settings in two Swedish counties.ParticipantsA consecutive sampling procedure included 725 patients discharged after hospitalisation due to angina, acute myocardial infarction, heart failure or atrial fibrillation.MeasurementTo evaluate the factor structure, confirmatory factor analyses based on polychoric correlations were performed (n=721). Internal consistency was evaluated by ordinal alpha. Test–retest reliability (n=289) was assessed with intraclass correlation coefficient (ICC).ResultsThe original six-factor structure was overall confirmed, but minor refinements were required to reach satisfactory model fit. The standardised factor loadings ranged between 0.68 and 0.94, and ordinal alpha ranged between 0.82 and 0.95. All subscales demonstrated satisfactory test–retest reliability (ICC=0.76–0.94).ConclusionThe revised version of the PCCQ showed sound psychometric properties and is ready to be used to measure perceptions of continuity of care. High ordinal alpha in some subscales indicates that a shorter version of the questionnaire can be developed.

Abstract Background The absence of Respectful Maternity Care (RMC) deters mothers from seeking maternity care services. Given the importance of RMC and the lack of a standard tool for its assessment in Iran, the present study was conducted to translate and assess the psychometric properties of the RMC questionnaire in Iranian women. Methods Forward-backward method was used for translating the questionnaire from English into Persian. A total of 265 postpartum women entered the study by simple random sampling from public and private hospitals in Tabriz, Iran. The validity of the questionnaire was confirmed through the face, content and construct validity. Construct validity was assessed through exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were used to confirm the reliability of the questionnaire. Internal consistency was examined by measuring the Cronbach’s alpha in a sample of 20 mothers, and test-retest stability by calculating the Intraclass Correlation Coefficient (ICC) in the same group of mothers, who had completed the questionnaire twice with a two-week interval. Results The exploratory factor analysis led to the extraction of one factor. Item 12 was eliminated due to its low factor loading. X2/df was less than 5, and RMSEA was less than 0.08, which confirms the validity of this model. The Cronbach’s alpha coefficient was obtained as 0.93 and ICC (with 95% confidence interval) as 0.98 (0.96 to 0.99). Conclusion The results of the study demonstrated that the Iranian RMC scale can be used as a valid and reliable instrument to assess RMC in Iran.

Abstract Background The Balance Evaluation Systems Test (BESTest) and its abbreviated version, the Mini-BESTest are clinical examination of balance impairment, but its psychometric properties have not yet been tested in European Spanish. We aimed to assess the psychometric properties of BESTest and Mini-BESTest in Spanish in community-dwelling elderly people. Methods We designed a cross-sectional transcultural adaptation and validation study. Convenience sample of thirty (N-30) adults aged 65 to 89 years old without balance problems were recruited. Two physiotherapists assessed participants at the same time. Internal consistency of Spanish BESTest and Mini-BESTest was carried out by obtaining the Cronbach Alpha. The reproducibility between raters was studied with the Intraclass Correlation Coefficient. The Pearson correlation coefficient was calculated by comparing the relationship between the BESTest, mini-BESTest, Berg Balance Scale (BBS) and Falls Efficacy Scale-International (FES-I). Results BESTest and Mini-BESTest showed good internal consistency. BESTest and Mini-BESTest total scores showed an excellent inter-rater agreement. There was a significant correlation between total score of the BESTest and the Mini-BESTest (r = 0.65; p < 0.001). BESTest had a moderate association with BBS and a strong association with FES-I. Mini-BESTest had a fair correlation with BBS and FES-I. Total scores obtained by women at BESTest and at Mini-BESTest were significantly lower than those reached by men. The differences observed in all the test when disaggregating data by sex require further research. Conclusions Spanish versions of BESTest and Mini-BESTest are comprehensible for new raters. They are reliable tools to provide information on which particular balance systems show impairment in community dwelling older adults. Elderly women had a worse quality of balance and a greater perception of their risk of falling. Trial registration This study was registered in ClinicalTrials.gov with NCT 03403218 on 2018/01/17.

AbstractThe effects of treatments on tinnitus have been difficult to quantify. The Tinnitus Functional Index (TFI) has been proposed as a standard questionnaire for measurement of tinnitus treatment outcomes. For a questionnaire to achieve wide acceptance, its psychometric properties need to be confirmed in different populations.To determine if the TFI is a reliable and valid measure of tinnitus, and if its psychometric properties are suitable for use as an outcome measure.A psychometric evaluation of the TFI from secondary data obtained from a cross-sectional clinic survey and a clinical trial undertaken in New Zealand.Confirmatory factor analysis and evaluation of internal consistency reliability were undertaken on a sample of 318 patients with the primary complaint of tinnitus. In a separate sample of 40 research volunteers, test–retest reliability, convergent and divergent validity were evaluated. Both samples consisted of predominantly older Caucasian male patients with tinnitus.The internal structure of the original US TFI was confirmed. The Cronbach’s Alpha and Intraclass correlation coefficients were >0.7 for the TFI overall and each of its subscales, indicating high internal consistency and test–retest reliability. Strong Pearson correlations with the Tinnitus Handicap Questionnaire and tinnitus numerical rating scales indicated excellent convergent validity, and a moderate correlation with the Hearing Handicap Inventory, indicated moderate divergent validity. Evaluation of the clinical trial showed good test–retest reliability and agreement between no-treatment baselines with a smallest detectable change of 4.8 points.The TFI is a reliable and valid measure of tinnitus severity in the population tested and is responsive to treatment-related change. Further research as to the TFI’s responsiveness to treatment is needed across different populations.

Abstract Background: The original Rainbow Model of Integrated Care Measurement Tool (RMIC-MT) is based on the Rainbow Model of Integrated Care (RMIC), which provides a comprehensive theoretical framework for integrated care. To translate and adapt the original care provider version of the RMIC-MT and evaluate its psychometric properties by a pilot study in Chinese primary care systems.Methods: The translation and adaptation process were performed in four steps, forward and back-translation, experts review and pre-testing. We conducted a cross-sectional study with 1610 community care professionals in all 79 community health stations in the Nanshan district. We analyzed the distribution of responses to each item to study the psychometric sensitivity. Exploratory factor analysis with principal axis extraction method and promax rotation was used to assess the construct validity. Cronbach’s alpha was utilized to ascertain the internal consistency reliability. Lastly, confirmation factor analysis was used to evaluate the exploratory factor analysis model fit.Results: During the translation and adaptation process, all 48 items were retained with some detailed modifications. No item was found to have psychometric sensitivity problems. Six factors (person- & community-centeredness, care integration, professional integration, organizational integration, cultural competence and technical competence) with 45 items were determined by exploratory factor analysis, accounting for 61.46% of the total variance. A standard Cronbach’s alpha of 0.940 and significant correlation among all items in the scale (>0.4) showed good internal consistency reliability of the tool. And, the model passed the majority of goodness-to-fit test by confirmation factor analysis Conclusions: The results showed initial satisfactory psychometric properties for the validation of the Chinese RMIC-MT provider version. Its application in China will promote the development of people-centered integrated primary care. However, further psychometric testing is needed in multiple primary care settings with both public and private community institutes.

The Mindful Eating Questionnaire is a reliable tool for the assessment of mindful eating behavior among the general population. This study aimed to determine the reliability and validity of The Malay Mindful Eating Questionnaire (MEQ-M) in a sample of overweight and obese adults. This is a cross-sectional survey which involved 144 overweight and obese adults in a selected public university. After linguistic validation of the Malay version of the MEQ, exploratory factor analysis (EFA) with varimax rotation was performed on the scale constructs. The psychometric properties of the MEQ were assessed through Cronbach’s alpha and intraclass correlation coefficient (ICC) analysis. The EFA of the MEQ produced a seven-dimensional model (58.8% of overall variances). The concurrent validity analysis between total MEQ scores and total Mindfulness Attention Awareness Scale (MAAS) scores indicated a weak non-significant correlation (p = 0.679). The internal consistency reliability of the MEQ was reasonable (Cronbach’s α = 0.64). The agreement stability of the MEQ over eight weeks was poor (ICC = 0.10). In conclusion, the psychometric properties of the Malay-translated MEQ are acceptable through construct validity and internal consistency reliability tests. This instrument may be used for assessing mindful eating habits in the Malaysian population, especially among overweight and obese adults.

Introduction: There is a need to have appropriate information about the ability of Parkinson's disease (PD) patients to perform cognitive instrumental activities of daily living (IADL). The purpose of the present study was to assess the psychometric properties of the Persian version of the Penn Parkinson's Daily Activities Questionnaire-15 (PDAQ-15). Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The Clinical Dementia Rating Scale, Hoehn and Yahr staging, Hospital Anxiety and Depression Scale (HADS) and Lawton IADL scale were included in the study. Internal consistency and test-retest reliability were evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages. Results: The PDAQ-15 showed strong internal consistency (Cronbach's α = 0.99) and test-retest reliability (ICC= 0.99). Only one dimension identified for the PDAQ-15 in the factor analysis. There was strong correlation between PDAQ-15 with depression domain of HADS scale and Lawton IADL scale. (rs = |0.71–0.95|). The correlation of PDAQ-15 with anxiety domain of HADS scale was moderate (rs = 0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages. Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument that can be useful in clinical and research settings.

Abstract Background:Although Oswestry Disability Index (ODI) is broadly used in clinical and research settings for assessing the disability level in patients with lumbar radiculopathy but it has not been translated into Urdu language according to the pre-established translation guidelines as well as the validity and reliability of ODI Urdu version has not been tested yet. The aim of this study was to translate ODI in native Urdu language (ODI-U) according to recommended guidelines and to measure its psychometric properties in Urdu speaking patients suffering from lumber radiculopathy. Methods: The ODI-U was developed through previously described translation procedures. 108 participants were recruited, out of which 54 were healthy and 54 were patients of lumber radiculopathy. ODI-U was filled by all participants. However, the patients were administered through ODI-U and visual analogue scales for disability (VAS disability) and pain intensity (VAS pain) at baseline and after 3 days. Reliability was investigated through test-retest method, internal consistency, standard error of measurement (SEM) and smallest detectable change (SDC) at 95% confidence level. ODI-U was assessed for exploratory factor analysis, construct (convergent and discriminative) validity and content validity. Alpha level <0.05 was considered statistically significant and psychometric standards were evaluated contrary to priori hypothesis.Results: The culturally adapted ODI-U revealed excellent test-retest reliability for total score (ICC=0.95) and for all item (ICC=0.72-0.98). Cronbach’s alpha of 0.89 showed excellent internal consistency and a moderate correlation between ODI-U total score and each item was observed through spearman’s correlation coefficient (r=0.51 to 0.76). One factor structure was created for ODI-U explaining 52.5% variance. There was no floor and ceiling effect of total ODI-U score showing good content validity. The discriminative validity was assessed by independent sample t-test which indicated significant difference in ODI-U total score between healthy and patients (P<0.001). The convergent validity was evaluated through Pearson’s correlation showing moderate correlation between ODI-U and VAS pain (r=0.49) as well as VAS disability (r=0.51).Conclusion: ODI-U showed adequate psychometric properties. ODI-U was found to be a reliable and a valid tool to measure the level of disability in Urdu-speaking patients with lumber radiculopathy.
