In spite of the ease of computation of Cronbach Coefficient Alpha, its misconceptions and mis-applications are still widespread, such as the confusion of consistency and dimensionality, as well as the confusion of raw Alpha and standardized Alpha. To clarify these misconceptions, this paper will illustrate the computation of Cronbach Coefficient Alpha in a step-by-step manner, and also explain ...

we examined the psychometric properties of the arabic version of the obsessive compulsive beliefs questionnaire-44 (obq-44) in a sample of kuwait university students. this questionnaire was developed by the obsessive compulsive cognitions working group in order to assess belief domains believed to be crucial in the development of obsessive compulsive symptoms.the arabic version of the obq-44 wa...

The paper discusses bankruptcy prediction model in the UK during the two last decades. My study is provided to support that the Original Altman’s Z-score (1968) might not valid to predict bankruptcy since the business environment changed a lot. However, there are many firms go to bankrupt recently and there is a need to study and improve the bankruptcy predictive ability. And the result shows t...

The aim of this study was to assess the repeatability of an observational gait analysis score that was developed specifically for unilateral amputees. Ten videotaped sequences were analysed by six experienced observers on two separate occasions. Data were analysed using percentage agreement, the kappa statistic and the coefficient of repeatability. The score demonstrated good intraobserver repe...

Abstract It is known since the 1970s that no more than 23 multiplications are required for computing product of two 3 × -matrices. For non-commutative coefficient rings, it not whether can also be done with fewer multiplications. However, there several mutually inequivalent ways doing job In this article, we extend list considerably by providing 17,000 new and schemes multiplying -matrices usin...

BACKGROUND The SF-36 and SF-12 summary scores were derived using an uncorrelated (orthogonal) factor solution. We estimate SF-36 and SF-12 summary scores using a correlated (oblique) physical and mental health factor model. METHODS We administered the SF-36 to 7,093 patients who received medical care from an independent association of 48 physician groups in the western United States. Correlat...
