Psychometric Investigation

The original 90-item Creative Behavior Inventory (CBI) was a landmark self-report scale in creativity research, and the 28-item brief form developed nearly 20 years ago is a popular measure of everyday creativity. Relatively little is known, however, about the psychometric properties of this widely used scale. In the current research, we conduct a detailed psychometric investigation into the 28-item CBI by applying methods from item response theory using a sample of 2,082 adults. Our investigation revealed several strengths of the current scale: excellent reliability, suitable dimensionality, appropriate item difficulty, and reasonably good item discrimination. Several areas for improvement were highlighted as well: (1) the four-point response scale should probably have fewer options; (2) a handful of items showed gender-based differential item functioning, indicating some item bias; and (3) local dependence statistics revealed clusters of items that are probably redundant. These analyses support the continued use of the CBI for assessing engagement in everyday creative behaviors and suggest that the CBI could benefit from thoughtful revision.

The Humor Styles Questionnaire (HSQ) is one of the most popular self-report scales in humor research. The present research conducted a forward-looking psychometric analysis grounded in Rasch and item response theory models, which have not been applied to the HSQ thus far. Regarding strengths, the analyses found very good evidence for reliability and dimensionality and essentially zero gender-based differential item functioning, indicating no gender bias in the items. Regarding opportunities for future development, the analyses suggested that (1) the seven-point rating scale performs poorly relative to a five-point scale; (2) the affiliative subscale is far too easy to endorse and much easier than the other subscales; (3) the four subscales show problematic variation in their readability and proportion of reverse-scored items; and (4) a handful of items with poor discrimination and high local dependence are easy targets for scale revision. Taken together, the findings suggest that the HSQ, as it nears the two-decade mark, has many strengths but would benefit from light remodeling.

The human ability for self-consciousness—the capacity to reflect on oneself and to think about one’s thoughts, experiences, and actions—is central to understanding personality and motivation. The present research examined the psychometric properties of the Self-reflection and Insight Scale (SRIS), a prominent self-report scale for measuring individual differences in private self-consciousness. Using tools from Rasch and item response theory models, the SRIS was evaluated using responses from a large sample of young adults (n = 1192). The SRIS had many strengths, including essentially zero gender-based differential item functioning (DIF), but a cluster of poor performing items was identified based on item misfit, high local dependence, and low item difficulty and discrimination. Based on the IRT analyses, a concise 12-item scale, evenly balanced between self-reflection and insight, was crafted. The short SRIS showed strong dimensionality, reliability, item fit, and local independence as well as essentially no gender DIF. Taken together, the many psychometric strengths of the SRIS support its popularity, and the short form will be useful for research and applied contexts where an efficient, concise version is needed.

Abstract Objective The Texas Functional Living Scale (TFLS) is a performance-based measure of functional abilities assessing the domains of time, money and calculation, communication, and memory. It is likely that certain items are more sensitive at different levels of functional impairment, with some signaling milder degrees of functional difficulty. This study analyzed psychometric characteristics of individual TFLS items using item response theory (IRT) in an outpatient clinical sample. Method In total, 270 adult outpatients completed the TFLS during clinical neuropsychological evaluation. IRT analysis using 2PL and graded response model was applied to the TFLS. Results Item parameters, item characteristic curves, and information curves were produced. Item difficulty (a) parameters ranged from 1.05 to 2.23, and item discrimination (b) parameters ranged from −4.11 to 0.51. Conclusions TFLS items were differentially sensitive along the continuum of functional impairment. Items that were most sensitive to milder degrees of functional impairment involved clock drawing, microwave programming, financial calculation, and prospective memory. Other items that were optimally precise in more severe degrees of functional impairment involved interacting with a calendar and a relatively simple financial calculation task. These findings suggest that the ability to pass at least some of the items on the TFLS may not necessarily reflect fully intact functional abilities. Certain TFLS items may be able to detect the presence of subtle functional difficulties.

Psychopathic Personality Inventory

This study examined item and scale functioning in the Psychopathic Personality Inventory–Revised (PPI-R) using an item response theory analysis. PPI-R protocols from 1,052 college student participants (348 male, 704 female) were analyzed. Analyses were conducted on the 131 self-report items comprising the PPI-R’s eight content scales, using a graded response model. Scales collected a majority of their information about respondents possessing higher than average levels of the traits being measured. Each scale contained at least some items that evidenced limited ability to differentiate between respondents with differing levels of the trait being measured. Moreover, 80 items (61.1%) yielded significantly different responses between men and women presumably possessing similar levels of the trait being measured. Item performance was also influenced by the scoring format (directly scored vs. reverse-scored) of the items. Overall, the results suggest that the PPI-R, despite identifying psychopathic personality traits in individuals possessing high levels of those traits, may not identify these traits equally well for men and women, and scores are likely influenced by the scoring format of the individual item and scale.

Applying the graded response model within the item response theory framework, the present study analyzes the psychometric properties of Karwowski’s creative self-efficacy (CSE) scale. With an ethnically diverse sample of US college students, the results suggested that the six items of the CSE scale were well fitted to a latent unidimensional structure. The scale also had adequate measurement precision or reliability, high levels of item discrimination, and an appropriate range of item difficulty. Gender-based differential item functioning analyses confirmed that there were no differences in the measurement results of the scale concerning gender. Additionally, openness to experience was found to be positively related to the CSE scale scores, providing some support for the scale’s convergent validity. Collectively, these results confirmed the psychometric soundness of the CSE scale for measuring CSE and also identified avenues for future research.
