Background: Undergraduate engineering students experiencing distress are less likely than peers to ask for professional help. A population-specific instrument to facilitate the identification of factors that influence mental healthcare utilization could guide development and testing of interventions to increase help seeking. Purpose: We used mixed…

In this paper I explore how Margaret Beier, Lesley Miller, and Shu Wang make claims for the validity and reliability of the instrument they developed to explore the construct of "possible selves" as described in their manuscript, "Science Games and the Development of Scientific Possible Selves."

Investigates some of the psychometric characteristics of the results from visual-analogue scales used to measure mental imagery. Reports that the scores from visual-analogue scales are positively related to scores from longer pencil-and-paper measures of mental imagery. Implications and limitations for the use of visual-analogue scales to measure…

Describes the design of an instrument to measure the attitudes of teachers toward metrication, and reports on its reliability and validity. (GA)

Designs a testing situation to examine the presence of combinatorial analysis, to establish construct validity in the use of an instrument, Combinatorial Analysis Behavior Observation Scheme (CABOS), and to investigate the presence of the schema in young adolescents. (Author/GA)
