Reliability, validity and psychometric properties of the Greek translation of the Major Depression Inventory.

ABSTRACT: BACKGROUND:The Major Depression Inventory (MDI) is a brief self-rating scale for the assessment of depression. It is reported to be valid because it is based on the universe of symptoms of DSM-IV and ICD-10 depression. The aim of the current preliminary study was to assess the reliability, validity and psychometric properties of the Greek translation of the MDI. METHODS:30 depressed patients of mean age 23.41 (+/- 5.77) years, and 68 controls patients of mean age 25.08 (+/- 11.42) years, entered the study. In 18 of them, the instrument was re-applied 1-2 days later and the Translation and Back Translation made. Clinical diagnosis was reached with the use of the SCAN v.2.0 and the International Personality Disorders Examination (IPDE). The Center for Epidemiological Studies-Depression (CES-D) and the Zung Depression Rating Scale (ZDRS) were applied for cross-validation purposes. Statistical analysis included ANOVA, the Spearman Product Moment Correlation Coefficient, Principal Components Analysis and the calculation of Cronbach's alpha. RESULTS:Sensitivity and specificity were 0.86 and 0.94, respectively, at 26/27. Cronbach's alpha for the total scale was equal to 0.89. The Spearman's rho between MDI and CES-D was 0.86 and between MDI and ZDRS was 0.76. The factor analysis revealed two factors but the first accounted for 54% of variance while the second only for 9%. The test-retest reliability was excellent (Spearman's rho between 0.53 and 0.96 for individual items and 0.89 for total score). CONCLUSION:The current study provided preliminary evidence concerning the reliability and validity of the Greek translation of the MDI. Its properties are similar to those reported in the international literature, but further research is necessary.

Project description:BackgroundDue to changes in Polish society resulting from a significant inflow of immigrants to Poland, the need to develop the cultural competences of various professional groups who have contact with immigrants in their work has increased. These groups should include healthcare professionals, especially because of the significant increase in the number of culturally diverse patients. Therefore, medical education in Poland has had to rapidly adapt to this novel situation. For instance, the teaching process should be now more focused on the development and evaluation of the cultural competences of prospective health care workers. However, there is still a lack of standardized, valid and reliable instruments to assess cross-cultural competences among healthcare professionals. The purpose of the present paper was to describe, for the first time, the translation, adaptation, and psychometric evaluation of the Polish version of the Cross-Cultural Competence Inventory.MethodsAcross two studies, we examined psychometric properties of the Cross-Cultural Competence Inventory (CCCI) such as reliability (i.e. internal consistency, test-retest reliability, factor structure) and validity (i.e. theoretical, criteria, convergent). In the first study, 408 participants (75% were healthcare professionals) completed the Polish version of the CCCI and the Positive/Negative Attitude Towards Culturally Divergent People Questionnaire. In the second study, 317 participants (97% were healthcare professionals) completed the CCCI twice, with an interval of at least 22 days. In addition, across two study sessions, participants completed questionnaires constructed to measure (a) cultural intelligence, (b) need for cognitive closure, (c) emphatic sensitiveness, (d) emotional intelligence, (e) self-esteem, (f) social desirability, and (g) personality. Finally, to additionally examine the theoretical validity, 36 professional cross-cultural competence trainers completed the CCCI during a one-session study.ResultsOur findings confirm the reliability and validity of the CCCI. More precisely, in study 1 we proved the theoretical validity and reliability (i.e. internal consistency) of the CCCI. While the assumed structure did not fit the data well, all items were significantly related to the general factor, thus providing strong support for the usage of the total score of the CCCI. In study 2, we additionally estimated the test-retest reliability and theoretical, criterion and convergent validity. Across two studies we were able to successfully confirm these psychometric properties. The reliability was satisfactory and ranged from .83 to .86. We also observed a high and significant positive correlation between CCCI and the Cultural Intelligence Scale, which measures a concept similar to the one measured by CCCI. In addition, a significant relationship between intercultural competences (CCCI) and other variables such as personality, empathic sensitivity, emotional intelligence, self-esteem (positive correlations) and the need for cognitive closure (mainly negative correlation) were demonstrated.ConclusionsThe obtained results support the usage of the CCCI questionnaire in scientific research, such as, for example, among healthcare professionals (nurses, doctors) and students of medical fields (nursing, medicine).

Project description:BackgroundThe upper limb functional index is broadly used outcome measure for musculoskeletal disorders of the upper limb. The main objective of the study was to translate and validate the upper limb functional index (ULFI) outcome measure in the Urdu language.MethodsUpper limb functional index was translated into Urdu language using Beaton et al. guidelines through forward and backward translation along with the expert committee reviews. Two fifty (n = 250) Urdu-speaking patients with sub-acute or chronic conditions of upper limb musculoskeletal disorders were included in the study. The mean age was 32.33 ± 4.67 years. The data were collected from the physical therapy department of The University of Lahore Teaching hospital. All participants completed the upper limb functional index-Urdu (ULFI-U), Numeric pain rating scale (NPRS), Quick Disability of arm, shoulder, and hand (QuickDash), and (health survey) SF-12 at baseline while only ULFI-U at day three. Reliability was assessed through internal consistency by Cronbach's alpha and test-retest reliability by intra-class correlation (ICC). Content validity was measured by Lynn and Lawshee method. Spearman's correlation has been used to measure criterion validity. The construct validity was measured through hypothesis testing. The structural validity has been explained through factor analysis by exploratory factor analysis (EFA) using Maximum likelihood extraction (MLE) with Promax rotation.ResultsThe English version of ULFI was translated into the Urdu language with minor alterations. The Urdu version ULFI has demonstrated high levels of reliability with intra-class correlation (ICC2,1= 0.91) and Cronbach's alpha (α = 0.94). The content validity index found as 0.808, the criterion validity for ULFI-U correlating with quick Dash was found excellent (r = 0.845) and ULFI-U established strong correlation with 6 domains of SF-12(r = 0.697 to 0.767) and weak correlation with its 2 domains and NPRS(r = 0.520). A two-factor structure was obtained using EFA.ConclusionsThe ULFI-U is a valid and reliable patient-reported outcome (PRO) that can be used to assess upper limb musculoskeletal disorders in Urdu-speaking patients.Trial registrationThis study was registered in the U. S National Library on clinicaltrial.gov under registration no. NCT05088096 . (Date: 21/10/2021).
