Behavior rating scales are commonly used in the assessment of attention deficit-hyperactivity disorder (ADHD). However, there is little information available concerning the extent to which scales are valid with culturally different students. This study explored the use of the ADHD-IV Rating Scale School Version with male Caucasian (CA) and African American (AA) students from ages 5 to 18 years....

Formatively measured constructs have been increasingly used in information systems research. With few exceptions, however, extant studies have been relying on the partial least squares (PLS) approach to specify and estimate structural models involving constructs measured with formative indicators. This paper highlights the benefits of employing covariance structure analysis (CSA) when investiga...

Over the past 15 years, the use of Partial Least Squares (PLS) in academic research has enjoyed increasing popularity in many social sciences including Information Systems, marketing, and organizational behavior. PLS can be considered an alternative to covariance-based SEM and has greater flexibility in handling various modeling problems in situations where it is difficult to meet the hard assu...

An investigation into support for restrictions on people testing seropositive for HIV is reported on. Data were collected during telephone interviews with two-hundred adults aged eighteen to sixty-five in the Chicago metropolitan area. Using the analytic technique of LISREL, six models which attempt to explain support for restrictions were tested. It was found that the model best supported by t...

The authors propose and test a model of the predictors and outcomes of the role conflicts experienced by individuals simultaneously holding full-time employment and providing care for elderly parents. It is proposed that interrole conflict is predicted by physical and psychological involvement in elder care and predicts both partial absenteeism from work and psychological strain. In turn, psych...

Burnout among human service professionals, such as nurses, has been studied in various countries for years using the Maslach Burnout Inventory (MBI). This paper reports on confirmatory factor analyses using LISREL that examined the factorial validity of the MBI. The sample consisted of 151 registered nurses from west-central Florida. Modifications of the initial hypothesized three-factor struct...

Background and Objective: It was hypothesized that within an invasively treated group and within a group that improved in angina pectoris no difference in effect size would occur between prospective and retrospective measures. Furthermore, it was hypothesized that assessment of perceived change at post-test may be invalid because of recall bias and present-state bias. Study Design and Setting: ...

This study examines consumers’ adoption behaviour of digital information products involving network effect and bandwagon effect simultaneously. Smartphone is selected as a typical object. We propose that perceived number of users is the common measurement of both effects. In addition, perceived complementarily is another factor of network effect, and bandwagon effect consists of popularity and ...

Purpose – E-trade, electronic trading appears to offer increased efficiency in business processes, but only a limited number of small firms have adopted the new processes. The purpose of this paper is to try to establish the obstacles, the perceived barriers, to the continuing use of e-trade technologies by small Korean firms. Design/methodology/approach – The literature was employed to develop...
