Cross-Cultural Adaption and Psychometric Evaluation of the German Craniofacial Pain and Disability Inventory (CF-PDI)

BACKGROUND: The Craniofacial Pain and Disability Inventory (CF-PDI) is a cross-culturally adapted instrument designed from a biopsychosocial perspective to measure pain, disability, and function in orofacial head and neck pain with shown psychometric properties; however, the German cross-cultural adaption is lacking. OBJECTIVES: To carry out a transcultural translation of CF-PDI into German and assess its psychometric properties in patients with painful temporomandibular disorders (TMD) with respect to construct and clinical validity, internal consistency and reproducibility. STUDY DESIGN: Multicenter, prospective, cross-sectional design. SETTING: Patients (n = 398) were recruited from dental and physical therapy clinics in middle and south Germany. METHODS: Structural validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). We investigated know-group validity by means of the scale’s potential to discriminate between affected and unaffected subjects. Multiple linear regression analysis was used to estimate convergent validity. We tested test-retest reliability by the intraclass correlation coefficient and the Internal consistency by Cronbach’s alpha, or each dimension separately, and the total score. Multiple linear regression analysis was used to estimate convergent validity. RESULTS: Two hundred forty-six heterogeneous chronic craniofacial pain patients and 152 patients without complaints were recruited from the middle and south of Germany. The German version CF-PDI-G presents 21 items, 4 factors, and adequate psychometric properties. The test-retest reliability and internal consistency of the CF-PDI-G were both excellent for the entire instrument and also for all sub-scales (intraclass correlation coefficient [ICC] > 0.90) except for the comorbidities and interference with work which was acceptable (ICC = 0.69). Standard error of the measurement (SEM) and minimal detectable change values are sufficiently low. Assessment of clinical validity shows good potential of discrimination and classification into categories “no,” “mild,” “moderate,” and “severe.” The multiple linear regression model showed a strong association between neck disability index, Visual Analog Scale, and anamnestic questionnaire (supporting the scale’s convergent validity). LIMITATIONS: Our sample has a higher prevalence of women and the sample was not recruited consecutively, which may lead to a biased estimation of psychometric properties. CONCLUSIONS: The CF-PDI-G represents valid and reliable instrument to assess pain and disability in patients with orofacial pain and headache suitable for research and clinical practice.

Test Retest Reliability

The English version of the Independent Television Commission-Sense of Presence Inventory (ITC-SOPI), which was developed in 2001 to measure how involved or present participants are when experiencing different media, has substantial psychometric evidence. This study was used to translate and validate the ITC-SOPI in interactive virtual environments among the Chinese population. We used the forward-backward translation procedure. An expert panel reviewed the translated ITC-SOPI until the Chinese version of the ITC-SOPI was finalized. A total of 210 participants (133 males and 77 females), with a mean age of 23.05 years ( SD = 3.56, range = 17–47), completed the Chinese ITC-SOPI. The following psychometric properties were examined: factor structure, internal consistency, test–retest reliability, and convergent validity. Confirmatory factor analysis (CFA) showed a good fit (χ2 /df = 1.70, Tucker–Lewis Index [TLI] = 0.91, comparative fit index [CFI] = 0.92, root mean square error of approximation [RMSEA] = 0.058) of the four-factor model (spatial presence, engagement, ecological validity, and negative effects). For each factor, the Chinese ITC-SOPI had high internal consistency (Cronbach’s α ranging from 0.75 to 0.87) and test–retest reliability (intraclass correlation coefficient ranging from 0.82 to 0.91). Significant correlations were identified between all factors and the Interpersonal Reactivity Index-C (IRI-C) and the Generalized Anxiety Disorder-7 (GAD-7). The Chinese ITC-SOPI had good psychometric properties, suggesting that it is a reliable and valid tool for evaluating media users’ sense of presence in a Chinese-speaking context.

Herth Hope Index

Objectives: This study aims to develop the Greek version of the Herth Hope Index (HHI) and assess its psychometric properties to a palliative care patient sample, using a cross-sectional design. Materials and Methods: The HHI was translated into Greek (HHI-Gr) using the ‘forward-backward’ procedure. It was administered to 130 eligible cancer patients, while for the stability of patients’ responses, 40 of these patients completed the HHI-Gr 3 days later. Along with the HHI-Gr, patients also completed the Hospital Anxiety and Depression Scale (HADS) and the Beck Hopelessness Scale (BHS). The HHI-Gr internal consistency reliability (Cronbach’s a), stability (intraclass correlation coefficient [ICC]), factor structure (factor analysis) and convergent validity (correlation with the HADS and the BHS questionnaires) were examined using the Eastern Cooperative Oncology Group (ECOG) performance status. Results: The HHI-Gr yielded a one-factor model and a Cronbach alpha (0.860) with excellent internal consistency reliability and stability ICC (>0.90). Satisfactory convergent validity was supported by the correlation analysis between the HHI-Gr and BHS (r = 0.718, P < 0.001). Overall test-retest reliability was satisfactory with a range between 0.77 and 0.96 (P < 0.001). Conclusion: These results demonstrate that the HHI-Gr is an instrument with satisfactory psychometric properties and is a valid research tool for the measurement of the levels of hope among Greek oncology patients.

Abstract Considering the importance of health risk behaviors (HRB) and the need for reliable instruments to evaluate them, this study was designed to evaluate the psychometric properties of the items of the Youth Risk Behavior Survey (YRBS) in a sample of 902 college students. Convergent validity, criterion, internal consistency, and temporal stability were evaluated. Higher correlations were observed between use of other drugs and use of marijuana (ρ = 0.537), and alcohol consumption and tobacco use (ρ = 0.418). Criterion validity was observed, with significant differences between domain scores according to gender. Adequate internal consistency, Cronbach’s alpha = 0.770 for overall scale. Most of the domains (82%) showed intraclass correlation coefficient ≥ 0.75 and 64.1% of the items showed kappa ≥ 0.60. The instrument seems to have indicators of criterion validity, internal consistency and temporal stability with satisfactory levels. We recommend that HRB assessment using YRBS should be performed separately on each domain.

Abstract Background Postural control is a very important function in everyday life. However, assessing postural control with commonly used measurement instruments (MIs) is limited due to deficits in their psychometric properties. The Mini-Balance Evaluation Systems Test (Mini-BESTest) is a comprehensive and multidimensional MI for assessing postural control in persons with limited balance function, such as individuals after stroke. Despite the increasing use of the Mini-BESTest worldwide, no German version is available. Research question Is the German version of the Mini-BESTest (GVMBT) comprehensible and valid for measuring postural control in individuals after stroke? Methods The Mini-BESTest was translated and cross-culturally adapted, following established guidelines. It was pilot-tested with ten participants. This observational measurement and validation study was conducted at one point and included 50 participants with subacute and chronic stroke (mean age: 64.58 ± 13.34 years/ 34 men/ 16 women). Convergent validity was investigated using 1) the Berg Balance Scale (BBS) and 2) the Timed “Up & Go” (TUG). The MIs were evaluated for normal distribution with the calculation of skewness, kurtosis and Q-Q-Plots. Spearman correlation coefficients and Bland Altman analysis were used to examine the relationship between the MIs. The internal consistency was assessed using Cronbach’s alpha. Results Comprehension of the GVMBT was confirmed. The GVMBT correlated significantly with the BBS (rs = 0.93) and the TUG (rs = − 0.85). Bland Altman analysis revealed low absolute differences. The GVMBT demonstrated no significant floor or ceiling effects and showed excellent internal consistency (Cronbach’s α = 0.90). Significance The GVMBT has excellent validity and internal consistency. Due to this and its specific subcategories, the GVMBT is recommended for the use in research and clinical practice. Further psychometric properties should be evaluated.

Different measuring tools have been used to understand the outcomes of end-stage renal disease (ESRD) therapies. However, survival, cost-effectiveness and quality of life (QOL) are the main parameters to evaluate treatment of ESRD. The current study meant to assess the psychometric properties (reliability and validity) of the Missoula-VITAS Quality of Life Index (MVQOLI-15) translation to Greek in patients undergoing hemodialysis (HD). A total sample of 79 HD patients voluntarily participated in this pilot study. Domain analysis of MVQOLI-15-Greek was conducted based on the collected data at initial assessment. The reliability properties of the instrument were tested using the following measures; internal consistency, repeatability, test-retest reliability and convergent validity. Domain analysis demonstrated that all domains of the questionnaire had good variability. MVQOLI-15-Greek internal consistency was satisfactory with an overall Cronbach’s a at 0.74. Pearson’s r and intraclass correlation coefficient revealed strong correlations (ranging from 0.91 to 0.98) between initial assessment and reassessment. MVQOLI-15-Greek convergent validity analysis indicated that the domains were strongly related to the same construct. The findings of the study indicate that the Greek version of MVQOLI-15 provided satisfactory psychometric properties supporting its use within pathological populations and in the context of national QOL measurement.

Abstract Background: Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing personal-level outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties. Methods: Patients receiving palliative care in hospice or hospitals completed the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms. Conclusion: Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

Background Cervical sagittal alignment plays an important role in the pathogenesis of cervical spondylotic myelopathy (CSM), but there are limited studies on the cervical sagittal parameters in CSM patients and their correlations with myelopathy. The aim of this study is to investigate the correlations among the preoperative cervical sagittal alignment parameters and their correlations with the development of myelopathy in patients with CSM. Methods We retrospectively collected 212 patients with CSM who underwent surgical interventions. Gender, age, modified Japanese Orthopedic Association score (mJOA), cervical lordosis (CL), C2–C7 sagittal vertical axis (C2–C7 SVA), T1 slope (T1S), neck tilt (NT) and thoracic inlet angle (TIA) were collected before operation. Interobserver and intraobserver reliability were calculated for all measurements (intraclass correlation coefficient, ICC). Data were analyzed with Pearson and Spearman correlation tests and multiple linear regression analysis. Results A total of 212 patients with CSM were included in this study (male: 136, female: 76) with an average age of 54.5 ± 10.1 years old. Intraobserver and interobserver reliability for all included radiographic parameters presented good to excellent agreement (ICC > 0.7). No significant differences in demographic and radiological parameters have been observed between males and females (P > 0.05). We found statistically significant correlations among the following parameters: age with CL (r = 0.135, P = 0.049), age with T1S (r = 0.222, P = 0.001), CL with T1S (r = 0.291, P < 0.001), CL with C2-C7 SVA (r = − 0.395, P < 0.001), mJOA with age (r = − 0.274, P < 0.001), mJOA with C2–C7 SVA (r = − 0.219, P < 0.001) and mJOA with T1S(r = − 0.171, p = 0.013). Linear regression analysis showed that C2–C7 SVA was the predictor of CL (adjusted R2 = 0.152, P < 0.001) and multiple linear regression showed that age combined with C2–C7 SVA was a sensitive predictor of mJOA (adjusted R2 = 0.106, P < 0.001). Discussion There were significant correlations among certain preoperative cervical sagittal parameters in CSM patients. CL was the only predictor of C2–C7 SVA. Age combined with C2–C7 SVA could predict the severity of myelopathy.

Abstract Background: Fatigue is the most disabling symptom in patients with multiple sclerosis (MS). Although there is no standard tool to evaluate fatigue in clinical settings, Fatigue Impact Scale (FIS), Fatigue Severity Scale (FSS) and Multidimensional Assessment of Fatigue scale (MAF) are popular instruments for this purpose. The aim of this study was to compare the psychometric properties of the Persian versions of these scales. Methods: 130 patients with MS and 60 healthy persons participated in this study. They completed the scales on two occasions 3 days apart. Reproducibility and internal consistency were evaluated as intraclass correlation coefficients (ICC) and Cronbach's alpha. Convergent validity was assessed by evaluating the association of the fatigue scales with age, sex, Expanded Disability Status Scale (EDSS), disease duration, and sleep quality. Dimensionality was evaluated with confirmatory factor analysis. Acceptability and known-group validity were also investigated. The effect size of all the scales was computed as well. Results: The ICC of all instruments was 0.99. Internal consistency was 0.97 for MAF, 0.93 for FSS, and 0.83 for FIS. The instruments showed moderate to good correlations with Pittsburgh Sleep Quality Index, EDSS, and duration of disease. Acceptability was acceptable. The FIS had three dimensions, and FSS and MAF were unidimensional. All scales were able to discriminate patients with MS from healthy people. Conclusions: The Persian version of MAF appears to be the most suitable instrument to evaluate fatigue in patients with MS based on its time-efficiency, effect size and detailed data about various aspects of fatigue.

Objective: There are presently no instruments available in German language to assess the therapeutic relationship in psychiatric care. This study validates the German version of the Scale to Assess the Therapeutic Relationship in Community Mental Health Care (D-STAR). Method: 460 persons with severe mental illness and 154 clinicians who had participated in a multicenter RCT testing a discharge planning intervention completed the D-STAR. Psychometric properties were established via item analysis, analyses of missing values, internal consistency, and confirmatory factor analysis. Furthermore, convergent validity was scrutinized via calculating correlations of the D-STAR scales with two measures of treatment satisfaction. Results: As in the original English version, fit indices of a 3-factor model of the therapeutic relationship were only moderate. However, the feasibility and internal consistency of the D-STAR was good, and correlations with other measures suggested reasonable convergent validity. Conclusions: The psychometric properties of the D-STAR are acceptable. Its use can be recommended in German-speaking countries to assess the therapeutic relationship in both routine care and research.
