The feasibility of the Golombok-Rust Inventory of Marital State (GRIMS) in assessing marital satisfaction in a Malaysian population

The purpose of this study is to validate the English version of the Golombok-Rust Inventory of Marital State (GRIMS) in a Malaysian population. Using the test-retest method and Cronbach's alpha, we assessed reliability and internal consistency. Sensitivity to change was expressed as the effect size. Internal consistency was excellent (Cronbach's alpha value = 0.59 to 0.91) Test-retest correlation coefficient and intraclass correlation coefficient were highly significant in majority items (ICC = 0.62 and above), and there was a high degree of sensitivity and specificity. The GRIMS is suitable, reliable, valid, and sensitive to clinical change in a Malaysian population.     

Psychometric properties of Turkish version of Dutch Eating Behaviour Questionnaire (DEBQ). A preliminary results

The purpose of this study was to test the reliability and validity of Dutch Eating Behaviour Questionnaire (DEBQ) among Turkish university students. The questionnaire was administered to 508 participants. Construct validity was assessed by principal component factor analysis with varimax rotation and reliability was tested by Cronbach's alpha coefficient. For testing criterion related validity, EAT-40 with DEBQ was also administered to 508 participants. Results showed the presence of three major factors (emotional eating, restrained eating and external eating) with loadings similar to those of the original questionnaire. Three subscales of DEBQ had higher internal consistency and test-retest reliability. The obtained correlation between EAT-40 and DEBQ was ranged from 0.12 to 0.39. This study clearly demonstrates the factorial validity and the reliability of a Turkish version of the DEBQ.     

Reliability and validity of the Norwegian version of the Functional Outcomes of Sleep Questionnaire

The aim of this study was to validate the Norwegian version of a self-administered 30-item quality of life questionnaire designed to assess disorders of excessive sleepiness, the Functional Outcomes of Sleep Questionnaire (FOSQ). In total 226 patients previously evaluated for obstructive sleep apnea were included in the study. The patients received a postal questionnaire with the FOSQ, the Short Form 36 (SF-36) questionnaire, and a scale for assessment of excessive daytime sleepiness, the Epworth sleepiness scale (ESS). Among the 178 respondents, all five subscales of the FOSQ showed good internal consistency reliability (Cronbach's alpha = 0.84-0.93). Test-retest on average 18 days apart was satisfactory with intraclass correlation coefficients ranging from 0.61 to 0.86. The pattern of Spearman's rank correlation coefficients between FOSQ scales and related and unrelated scales SF-36 scales gave support to the construct validity of the FOSQ. In conclusion, the Norwegian translation of the FOSQ showed satisfactory internal consistency reliability, test-retest reliability and construct validity, in line with the original version.     

Validation of the care transition measure in multi-ethnic South-East Asia in Singapore

ABSTRACT: BACKGROUND: The 15-item Care Transition Measure (CTM-15) is a measure for assessing the quality of care during transition from the patients' perspective. The purpose of this study was to test the psychometric properties of the CTM-15 and CTM-3 (a 3-item version of the CTM-15) in Singapore, a multi-ethnic urban state in South-east Asia. METHODS: A consecutive sample of patients was recruited from two tertiary hospitals. The subjects or their proxies were interviewed 3 weeks after discharge from hospital to home in English or Chinese using the CTM-15 questionnaire. Information about patients' visit to emergency department (ED), non-elective rehospitalisation for the condition of index hospitalisation, and care experience after discharge was also collected from respondents. Psychometric properties of CTM-15 and CTM-3 based on the five-point response scale (i.e. strongly disagree, disagree, neutral, agree, and strongly agree) and the three-point response scale (i.e. [strongly] agree, neutral, and [strongly] disagree) were tested for English and Chinese versions separately. Internal consistency reliability was assessed using Cronbach's alpha and construct validity was tested with T-test or Pearson's correlation by examining hypothesised association of CTM scores with ED visit, rehospitalisation, and experience with care after discharge. Exploratory factor analysis was performed to examine latent dimensions of CTM-15. RESULTS: A total of 414 (proxy: 96.1 %) and 165 (proxy: 84.8 %) subjects completed the interviews in English and Chinese, respectively. Cronbach's alpha values of the different CTM-15 versions ranged from 0.81 to 0.87. In contrast, Cronbach's alpha values of the CTM-3 ranged from 0.42 to 0.63. Both CTM-15 and CTM-3 were correlated with care experience after discharge regardless of survey language or response scale (Pearson's correlation coefficient: 0.36 to 0.46). Among the English-speaking respondents, the CTM-15 and CTM-3 scores based on both the three- and five-point response scales discriminated well between patients with and without ED visits or rehospitalisation for their index condition. Among Chinese-speaking respondents, no difference in CTM scores was observed between patients with and without ED visits or patients with and without rehospitalisation. The English and Chinese versions of the CTM-15 items demonstrated a similar 4-factor structure representing general care plan, medication, agreement on care plan, and specific care instructions. CONCLUSIONS: The care transition measure is a valid and reliable measure for quality of care transition in Singapore. Moreover, the care transition measure can be administered to proxies using a simpler response scale. The discriminatory power of the Chinese version of this instrument needs to be further tested in future studies.
