Scale validation via quantifying item validity using the Dm index

While most validity indices are based on total test scores, this paper describes a method for quantifying the construct validity of items. The approach is based on the item selection technique originally described by Piazza in 1980. Unfortunately, Piazza's P2 index suffers from some substantial limitations. The Dm coefficient provides an alternative which can be used for item selection and provides a validity index for a set of items. The index is similar to that of traditional criterion-related validity indices. Criterion-related validity is used to demonstrate the accuracy of hypothesized relations of the measure with outcome variables of interest in research and practice. This method may be useful when the sample of items or persons is small, rendering more traditional approaches such as factor analysis or item response theory inappropriate. An example of how to use the technique is provided.     

Perceptions of morality and competence in (non)interdependent games

Individuals’ actions and their stated beliefs affect how others perceive them. In a prisoner’s dilemma, a defector who expects others to cooperate is perceived as less moral than a defector who expects others to defect; a cooperator who expects others to defect is perceived as less competent than a cooperator who expects others to cooperate (Experiment 1). This pattern suggests that in a context of interdependence, a stated expectation that the behavior of others will resemble one’s own may protect one’s social reputation. When outcomes are not interdependent, expectations do not moderate the effects of behavior on reputation (Experiment 2). In such a context, inductive reasoning is sufficient to explain social projection. Both types of results are replicated in a modified N-person social dilemma (Experiment 3), further validating the inductive-reasoning hypothesis.     

The midwife case: Do they “walk the talk”?

Expertise depends on hours and hours of practice within a field before a state of proficiency is achieved. Normally, expert skills involve bodily knowledge associated to the practices of a field. Interactional expertise, i.e. the ability to talk competently about the field, however, is not causally dependent on bodily proficiency. Instead, interactional experts are verbally skilled to an extent that makes them impossible to distinguish from so-called contributory experts, the experienced practitioners. The concept of interactional expertise defines linguistic skills as contingent on bodily knowledge. However, recent neuropsychological findings make it plausible that “first-person”-related neural activations would be relevant with respect to the subjects' verbal output, at least when subjects address concepts that refer to tangible objects. Using imitation games, we explore and expand on the apparently arbitrary relation between bodily experiences and linguistic skills in midwifery. In alignment with several findings within grounded cognition studies, the results presented suggest that somehow personal experiences make a linguistic difference, noticeable to contributory experts.     

Perceptions and Punishments of Workplace Aggression: The Role of Aggression Content,Context, and Perceiver Variables1

Aggressiveness and sanctioning ratings made by 360 undergraduates to scenarios of workplace aggression suggest that aggressor gender, occupational status of aggressor relative to the target of aggression, and type of aggression content (i.e., hostility, obstructionism, or overt) affected these ratings. The results support hypothesized main effects for aggression content and aggressor gender, and also a significant interaction between occupational status and aggressor gender. However, the results failed to confirm hypotheses that perceiver variables (e.g., trait aggression) would add significantly to the prediction of either aggressiveness ratings or sanctioning ratings. Implications for policy formation to manage aggressive individuals in organizations are discussed.     

A Model of Competence for Counting

A theoretical framework Is presented that distinguishes among three knowledge sources that form the basis for generative performance. The three knowledge sources, termed conceptual, procedural, and utilizational competence, were implemented as a computational model that derives plans for counting procedures. In a previous analysis, Greeno, Riley, and Gelman (1984) developed a characterization of the conceptual competence (implicit understanding of general concepts and principles) associated with the skill of counting and related conceptual competence to various models of performance. In the current work all three knowledge sources are formalized in a computer program (COUNTPLAN) that generates planning nets of counting procedures. The sufficiency of COUNTPLAN's knowledge components is demonstrated through its capacity to generate new plans for counting in novel settings from a core of conceptual competence. The utility of COUNTPLAN to facilitate the distinction between hypotheses of competence and hypotheses of performance is discussed.

“Vamos a la Escuelita Arte Terapia”: An Art Therapy Protocol for Promoting Resilience with Latino Farm Worker Children

Children of Latino farm worker families risk experiencing emotional and behavioral issues. Yet mental health resources are often inaccessible because of transportation and communication disparities. Subsequently, there is a need for accessible therapy-based programs which cross language and cultural barriers. The pilot study, la Escuelita Arte Terapia, sought to address the compounding needs of the children by running a six-week art therapy protocol within a Latino farm worker community in southern Georgia. The average attendance was 95 percent, with approximately 25 children between the ages of 2 and 7 attending each session. Observational data revealed that several therapeutic goals were successful in building internal resiliency while working to reduce risk factors and improve the participant’s school-readiness. Specifically, participants displayed increased developments in their fine and gross motor skills, creative development, emotional expression, behavioral focus, and social engagement. Several factors contributed to the success of la Escuelita Arte Terapia, which included how the promotores acted as mediators between the art therapists and the families, the art therapists’ supportive role, the art therapy milieu, and the community connections. It is hoped that future endeavors will build on the intervention proposed to help determine how art therapy can address emotional and behavioral disparities with Latino farm worker children.     

Prevalence and correlates of suicidal behavior among adult female victims of intimate partner violence

The prevalence and correlates of suicidal threats and attempts among 662 racially and ethnically diverse adult female victims of intimate partner violence (IPV) were studied. One in five women had threatened or attempted suicide during her lifetime. They observed that multiple logistic regression results indicated that women at greater risk of severe or potentially lethal assaults as measured by the Danger Assessment and those who reported having a chronic or disabling illness were more likely to have threatened or attempted suicide. A linear association was found between age and suicide threats/attempts, with younger women having increased odds. Finally, African American IPV victims were less likely to have threatened or attempted suicide as compared to Latina victims. Study implications are discussed.
