OBJECTIVE To assess the reliability of the Kids' Activity and Nutrition Questionnaire (KAN-Q) as part of a tiered process for developing Supplemental Nutrition Assistance Program-Education tools. METHODS The KAN-Q was administered at 2 time points to assess internal consistency using standardized values of Cronbach α and test-retest reliability using the intraclass correlation coefficient for...

Typically, when using existing scales, researchers conduct a confirmatory factor analysis and estimate reliability indices such as Cronbach alpha. Results are then used to select items that are subsequently incorporated in models. However, this process is inefficient as results from several studies consistently indicate that certain factors have low factor loadings. This study addressed this is...

OBJECTIVES To assess the reliability and validity of the Brazilian version of the Attentional Function Index. METHOD Methodological study. The sample was made up of 138 students from an undergraduate nursing course. The psychometric properties were assessed through the convergent construct validity, using the Brazilian version of the Attentional Function Index and the Portuguese-language vers...

On the basis of an empirical study of measures of constructs from the cognitive domain, the personality domain, and the domain of affective traits, the authors of this study examine the implications of transient measurement error for the measurement of frequently studied individual differences variables. The authors clarify relevant reliability concepts as they relate to transient error and pre...

Purpose: The main goals of this study were to translate and assess the psychometric properties and reliability of the Portuguese version of the SAQOL-39 in a group of chronic aphasia patients. Methods: We used the translation and retroversion method from the original scale to ensure conceptual uniformity. The instrument was administered to 33 aphasia patients. Internal consistency was assessed ...

The authors are preparing for cross-cultural studies of immunosuppressive behaviors and emotions, commonly called "Type C," in both healthy persons and in patients with cancer. To this end, validity and reliability of a Type C Personality Inventory were assessed in a sample of 128 healthy volunteers. Reliability of the instrument was supported by moderate to high Cronbach alpha coefficients. Ac...

OBJECTIVE To determine the validity and reliability of a nutrition knowledge questionnaire for adults in California. METHODS A convenience sample of adults was recruited for cognitive interviews. A mail-based survey of 400 randomly selected addresses was used to assess internal consistency (Cronbach α). Researchers assessed content validity (Student t test) and test-retest reliability (Pearso...

UNLABELLED Examinations at the Faculty of Medicine of Mu'tah University are based on a single best answer multiple-choice questions (MCQs) format. However, the reliability of this examination format has not been determined. OBJECTIVE Using an examination of obstetrics and gynaecology as a model, this study aims to analyze the difficulty (facility) index, the discriminatory power and reliabili...

IMPORTANCE Because tonsillar enlargement can have substantial ill health effects in children, reliable monitoring and documentation of tonsil size is necessary in clinical settings. Tonsil grading scales potentially allow clinicians to precisely record and communicate changes in tonsil size, but their reliability in a clinical setting has not been studied. OBJECTIVE To assess the interobserve...

STUDY DESIGN Questionnaire translation and validation. OBJECTIVE The aim of this study was to translate and cross-culturally adapt the Early Onset Scoliosis-24 item Questionnaire (EOSQ-24) into traditional Chinese, and to assess its validity, reliability, and sensitivity in Southern-Chinese patients diagnosed with early onset scoliosis (EOS). SUMMARY OF BACKGROUND DATA Relying on radiograph...
