Persian Translation, Internal Consistency and Reliability of Wolf Motor Function Test
Background: Wolf Motor Function Test (WMFT) is used in the assessment of upper extremity motor function in stroke patients. This scale contains 15 items and assesses joint-segment movements and functional tasks. Objectives: Translation and assessment of internal consistency and reliability of the Persian version of WMFT in Iranian stroke patients. Materials and Methods: After translation ...
متن کاملThe Adaptation and Experience of Four Shoulder Patient–Centered Outcome Scores
Objective: The aim of this study was to achieve a reliable tool for measuring health related quality of life among Iranians with shoulder pain and disability. Materials & Methods: Through a non-experimental methodology study, four shoulder patient-centered outcome scores were translated and adapted culturally to Persian language. A total of 126 male and female patients with shoulder pain and...
متن کاملDevelopment of a Digital-Based Instrument to Assess Perceived Motor Competence in Children: Face Validity, Test-Retest Reliability, and Internal Consistency
Assessing children’s perceptions of their movement abilities (i.e., perceived competence) is traditionally done using picture scales—Pictorial Scale of Perceived Competence and Acceptance for Young Children or Pictorial Scale of Perceived Movement Skill Competence. Pictures fail to capture the temporal components of movement. To address this limitation, we created a digital-based instrument to ...
متن کاملEffect of Varying Sample Size in Estimation of Coefficients of Internal Consistency
Reliability refers to accuracy of a measurement instrument or scale. Reliability of test scores are estimated through measures of internal consistency has been characterized mathematically in many ways that appear, on the surface at least, to be very different to one another. The coefficient alpha is the most widely used measure of internal consistency for composite scores. In this article, the...
متن کاملA reliability generalization meta-analysis of self-report measures of adult attachment.
This study is a reliability generalization meta-analysis that reviews 5 of the most frequently used continuous measures of adult attachment security: the Adult Attachment Scale, Revised Adult Attachment Scale, Adult Attachment Questionnaire, Experiences in Close Relationships, and Experiences in Close Relationships-Revised. A total of 313,462 individuals from 564 studies provided 1,629 internal...
متن کاملCoefficient alpha and related internal consistency reliability coefficients.
The author studied the conditions under which coefficient alpha and 10 related internal consistency reliability coefficients underestimate the reliability of a measure. Simulated data showed that alpha, though reasonably robust when computed on n components in moderately heterogeneous data, can under certain conditions seriously underestimate the reliability of a measure. Consequently, alpha, w...
