Development of a Distance-Based Effect Size Metric for Single-Case Research: Ratio of Distances

This article describes the development of an effect size measure called Ratio of Distances (RD). The goal was to develop a measure of level change for single case experimental research that met several practical requirements: (a) the measure is adaptable to designs with varying numbers of observations per, and across, phases; (b) the measure is adaptable to situations in which slope does and does not exist; (c) the measure has no ceiling, as is the limitation with commonly used overlap-based measures of effect size; and (d) the measure is computationally transparent and easily computed using widely available analysis tools (e.g., Microsoft Excel). The measure is applicable to single cases and meta-analyses.     

An information theoretic measure for the evaluation of ordinal scale data

This article describes a new measure of dispersion as an indication of consensus and dissention. Building on the generally accepted Shannon entropy, this measure utilizes a probability distribution and the ordered ranking of categories in an ordinal scale distribution to yield a value confined to the unit interval. Unlike other measures that need to be normalized, this measure is always in the interval 0 to 1. The measure is typically applied to the Likert scale to determine degrees of agreement among ordinal-ranked categories when one is dealing with data collection and analysis, although other scales are possible. Using this measure, investigators can easily determine the proximity of ordinal data to consensus (agreement) or dissention. Consensus and dissention are defined relative to the degree of proximity of values constituting a frequency distribution on the ordinal scale measure. The authors identify a set of criteria that a measure must satisfy in order to be an acceptable indicator of consensus and show how the consensus measure satisfies all the criteria.     

The recurrence ratio

The rationale for and method of computing a measure of stuttering recurrence that is superior to methods previously developed is presented. This measure, the recurrence ratio, contrasts especially with the traditional measure of “consistency,” the percentage measure, which yields misleading values.     

Further validation of a measure of irrational belief

Malouff and Schutte (1986) developed a measure of irrational belief intended to be shorter and more content valid than other such measures and reported preliminary evidence of reliability and validity for the measure. The present two studies examined further the validity of the new measure. Study 1 produced evidence of construct validity in that a significant correlation was found between scores on the Malouff & Schutte measure and scores on a measure of hostility, which is a theoretically related construct. Study 2 produced evidence of construct validity in that scores on the Malouff & Schutte measure were found to be correlated with scores on two measures of theoretically related constructs: anxiety and irrational tendencies/beliefs. Study 2 also produced evidence of discriminant validity in that scores on the Malouff & Schutte measure were found to be significantly more highly correlated with scores on the more theoretically similar irrational tendencies/beliefs scale than with scores on the anxiety measure.     

Facet measures and global job satisfaction

This research was an attempt to find evidence for Scarpello and Campbell's (1983) conclusion that a single-item global measure is more content valid than a composite facet measure for assessing overall job satisfaction. The first study investigated responses from employees in three separate plants who completed a facet measure, a single-item global measure, along with items and facets chosen by an employee committee. Results indicated that the employee-chosen facets accounted for some incremental variance in the prediction of the single-item measure. A second study investigated the relationship between a single-item and a facet measure of benefit package satisfaction when the entire benefit package domain was included in the facet measure. The magnitude of the relationship suggested that the single-item measure of global benefit package satisfaction involved consideration of more than merely satisfaction with each element in the package. Limitations and alternative explanations for the findings are discussed.The helpful comments of Mark E. Tubbs and John W. Jones on an earlier version of this article are greatly appreciated.     

Personality correlates and sex differences in the topological representations of self and others

This investigation attempted to identify the underlying components of the Social Self-Esteem measure. Although devised to function as a brief nonverbal measure of self-esteem applicable to a wide range of special populations, understanding of the measure remained limited. Relationships of this measure to related personality constructs and socioeconomic variables were examined to develop a clearer picture of what the Social Self-Esteem measure is actually assessing. Results indicated that the personality factor Capacity for Status was significantly related to the measure's assessment only among males. it was suggested that the Social Self-Esteem measure assesses some aspect Of what may be termed an individual's status ideal. The usefulness of differentiating scoring levels on the measure is demonstrated. Reasons for the lack of measurement usefulness among females were discussed, in terms of continued reliance among females upon significant others for status satisfaction.     

Hyperactive and normal children and the error,latency, and double median split scoring procedures of the matching familiar figures test

To further evaluate the construct validity of Kagan's Matching Familiar Figures Test (MFF), three different scoring methods—the MFF error measure, the MFF latency measure, and Kagan's double median split—were used to compare learning disabled and behavior disordered boys at two age levels with their normal peers on the frequency with which they were designated as impulsive. In the comparison of 7-year-old and 12-year-old learning disabled boys with the normal children, the MFF error measure identified a greater frequency of the learning disabled boys as impulsive at both age levels. No differences occurred between the learning disabled and the normal boys at either age level on the latency measure. Kagan's double median split procedure differentiated only between the older learning disabled and the normal boys. Thus, combining the latency measure with the error measure detracted from the effectiveness of the error measure. None of the MFF scoring procedures differentiated between the behavior disordered and the normal boys at either age level. Although the findings tend to support the results of studies with normal children in indicating that the error measure is more sensitive than the latency measure, the failure of the error measure to designate a greater frequency of the severely behavior disordered boys as being impulsive than are their normal peers raises further questions about the construct validity of the MFF, regardless of the scoring procedure used.     

Forced-choice assessments of personality for selection: evaluating issues of normative assessment and faking resistance

Recent research suggests multidimensional forced-choice (MFC) response formats may provide resistance to purposeful response distortion on personality assessments. It remains unclear, however, whether these formats provide normative trait information required for selection contexts. The current research evaluated score correspondences between an MFC format measure and 2 Likert-type measures in honest and instructed-faking conditions. In honest response conditions, scores from the MFC measure appeared valid indicators of normative trait standing. Under faking conditions, the MFC measure showed less score inflation than the Likert measure at the group level of analysis. In the individual-level analyses, however, the MFC measure was as affected by faking as was the Likert measure. Results suggest the MFC format is not a viable method to control faking.     

Subjective Difficulty of Movements With Ongoing Visual Control

Objective difficulty of a single-component visually controlled movement may be defined by Fitts's (1954) Index of Difficulty, which is a measure of difficulty in the sense that movement time is linearly related to the objective measure. For movements that have multiple components, it becomes difficult to determine an objective measure of task difficulty due to unknown interactions between components of the movement and interactions with other factors. Thus, it may be necessary to use indirect methods for allocating a measure of task difficulty. The purpose of the study was to determine whether participants could validly construct a subjective measure of the movement difficulty and whether this measure was related to the known objective measure of difficulty. Experiments showed that for single-component movements, there was a close relationship between measures of subjective and objective difficulty. With two-component visually controlled movements it was found that subjective difficulty could be related to objective difficulty, but not as simply as for single-component tasks.     

Confirmation and justification. A commentary on Shogenji’s measure

So far no known measure of confirmation of a hypothesis by evidence has satisfied a minimal requirement concerning thresholds of acceptance. In contrast, Shogenji’s new measure of justification (Shogenji, Synthese, this number 2009) does the trick. As we show, it is ordinally equivalent to the most general measure which satisfies this requirement. We further demonstrate that this general measure resolves the problem of the irrelevant conjunction. Finally, we spell out some implications of the general measure for the Conjunction Effect; in particular we give an example in which the effect occurs in a larger domain, according to Shogenji justification, than Carnap’s measure of confirmation would have led one to expect.     

Developing a sense of virtual community measure.

Sense of virtual community is an important feature of virtual communities. This study develops a sense of virtual community (SOVC) measure, building off the strengths of a widely used measure of sense of community (SOC) for face-to-face communities. Although there is overlap between the senses of community for face-to-face and virtual communities, there are significant differences. The new SOVC measure is compared to the SOC measure on 265 members of seven online groups, explaining at least 7% more of the variance from exchanging support and member identification. This study represents an important step in developing a valid measure of SOCV.     

Measuring Processing Fluency: One versus Five Items

While there is an ample amount of consumer behavior research that recruits processing fluency as an explanatory construct, the question how to best measure the fluency experience has received little attention. Therefore, there is a lack of consistency in measuring the construct, particularly with regard to the use of single‐item versus multi‐item measures. The current research, thus, aims to investigate how processing fluency can be consistently measured across different experimental fluency manipulations and which type of measure has the highest validity. Based on classic scale development procedures, we propose a reliable and valid multi‐item measure and compare this measure against a single‐item measure in terms of predictive validity. We show that both measures mediate the effect of five established fluency manipulations and that the single‐item measure is sufficient. In addition to providing a measure for future research that can be adapted to different empirical settings, we provide empirical evidence on the replicability of fluency effects and on the theoretical conjecture that people have a uniform fluency experience across different manipulations of fluency.     

Test of the validity of the Vando R-A Scale

The purpose of this study was to gather evidence on the validity of the Vando R-A Scale, a paper-and-pencil measure of perceptual reactance. The Vando R-A Scale and Petrie's kinesthetic aftereffect measure of perceptual reactance were administered to 46 participants drawn from university undergraduates. The Vando R-A Scale was not a valid measure of perceptual reactance. The continued use of the Vando R-A Scale as an alternate measure of perceptual reactance is contraindicated.     

Contribution d’une catégorisation des RPS à la prédiction du stress et du burnout (ou du mal-être au travail) des soignants

Health-care professionals are strongly affected by distress at work. Our goal is to study the usefulness of a psychosocial risk measure, compared to a measure of psychosocial and organizational work constraints, on the prediction of distress among a population of caregivers. This measure is based on the categorization of psychosocial risk factors issued from the College of experts chaired by Gollac. Seven hundred and fifty-seven health-care professionals filled out a questionnaire composed of measures of psychosocial risks, psychosocial and organizational work constraints specific to caregivers, as well as stress and burnout. Results indicate that the measure of psychosocial risk better predicted the levels of stress and burnout than the measure of psychosocial and organizational work constraints.     

Conceptualizing Sex Offender Denial From a Multifaceted Framework: Investigating the Psychometric Qualities of a New Instrument

The authors examined the psychometric properties of a clinician‐rated measure of sex offender denial. Convergent and discriminant validity for the measure was supported, and given its relationship to treatment attitudes, the measure demonstrated utility for assessing treatment change and readiness.     

Enactivism and predictive processing: a non-representational view

This paper starts by considering an argument for thinking that predictive processing (PP) is representational. This argument suggests that the Kullback–Leibler (KL)-divergence provides an accessible measure of misrepresentation, and therefore, a measure of representational content in hierarchical Bayesian inference. The paper then argues that while the KL-divergence is a measure of information, it does not establish a sufficient measure of representational content. We argue that this follows from the fact that the KL-divergence is a measure of relative entropy, which can be shown to be the same as covariance (through a set of additional steps). It is well known that facts about covariance do not entail facts about representational content. So there is no reason to think that the KL-divergence is a measure of (mis-)representational content. This paper thus provides an enactive, non-representational account of Bayesian belief optimisation in hierarchical PP.

Assessing the Development of Relationships: A New Measure

This paper describes the development and application of a procedure (The Relationship World Index) to measure the development of intimate relationships. Grounded in symbolic interaction theory, the Relationship World Index is a measure of agreement on important aspects of relationships between members of intimate dyads. The development of the measure was guided by assumptions inherent in symbolic interactionism that predict the emergence of a shared construction of reality that bonds relationship members. Research results are presented providing evidence for the reliability and validity of the measure.     

Measuring Airman Job Performance Using Occupational Survey Data

This research effort produced a task-based measure of job performance using data from existing Air Force occupational surveys. Previous performance measures col- lected in the field during the Air Force Job Performance Measurement (JPM) program were time consuming and expensive because they involved hands-on observation and measurement. The alternative, low-cost, readily available measure developed in this study accounted for the number and difficulty of job tasks performed by an airman and was validated against data from the JPM program using airman aptitude and experience as predictor variables. Results showed that the occupational task-based performance measure rank ordered airmen similarly to the JPM measure in terms of average performance, suggesting its value as a more cost-effective measure of work productivity.
