Construction of a depression scale with the Rasch model

This study examines the psychometric properties of a depression questionnaire. The goal was to improve the technical quality of traditional measures of depression in Spanish youth. 310 participants, aged 18-24 years, filled in the self-report questionnaire. The data were analyzed by means of the Rasch model. Results show that model fit, average item reliability (.97), and average person reliability (.88) are high. After deleting four indicators showing misfit and 12 showing sex bias, the resulting scale measures clinical depression objectively. Using this scale, the expected sex-related differences are found.     

Cross-linguistic assessment of verbal production from a narrative task in Williams Syndrome

Williams Syndrome (WS) is a disorder caused by a delection in chromosome 7, with a cognitive profile characterised by mild to moderate mental deficiency and difficulties in visual-spatial processing, which contrasts with a relative preservation of linguistic functions and narrative production. In this study, verbal performance was analysed in two groups of participants (N = 3), Portuguese and Spanish, genetically diagnosed with WS. Scores were low in Verbal IQ, as in Performance IQ. Narrative performance showed low coherence with respect to structure, process, and content. WS verbal performance was affected and there was no difference between both groups. We could not find any dissociation between cognitive functioning and linguistic production.     

Assessing Violence Risk: A Review and Clinical Recommendations

Guidance to identify and manage clients with a perceived high risk for future violence is of great importance for mental health professionals. In the past decade, several structured instruments have been developed to assess risk of future violence. Awareness of the limits and abilities of such instruments is required. This article reviews the most well‐known risk assessment tools and provides recommendations for how to approach the area of violence risk assessment.     

Spirituality and Counselor Competence: A National Survey of American Counseling Association Members

A random sample of 505 American Counseling Association (ACA) members completed a questionnaire that evaluated respondents' ratings of the importance of 9 competencies developed at the Summit on Spirituality (G. Miller, 1999; “Summit Results,” 1995) meetings to effectively address spiritual and religious issues in counseling practice. Results suggest that, in general, ACA members strongly support the importance of the competencies for effective counseling practice.     

Single‐limit interval estimates as reference points

People often describe uncertain quantities by suggesting a lower or upper limit of an uncertainty interval, rather than the complete range. Five studies are reported, which demonstrate how interval limits function as provisional reference points (PRP), conferring evaluative meanings to the target objects, by suggesting downward or upward comparisons. Thus, a price above X appears expensive, whereas a price below Y appears cheap, even when Y > X. This can give rise to framing effects: a purchase can appear to be recommended or advised against, and a seller can appear as optimistic or pessimistic, and, more generally, an estimate can indicate abundance or scarcity, depending upon which boundary (upper or lower) that is selected. Furthermore, inclusive lower bounds (minimum, at least) and upper bounds (maximum, at most) differ from exclusive lower (more than, above) and upper bounds (less than, below), by suggesting possible (likely) rather than implausible (unlikely) values.

The Role of Job Challenge and Organizational Identification in Enhancing Creative Behavior among Employees in the Workplace

Organizations recognize the importance of creative employees and constantly explore ways to enhance their employees' creative behavior. Creativity research has directed substantial efforts to understanding how work environment fosters creativity. Yet, this research has paid little attention to the importance of specific characteristics of the work environment and organizational identification in augmenting creative behavior in employees at work. The present study examines the influence of job challenge on employees' creative behavior, arguing that organizational identification plays a mediating role in this relationship. The results show that organizational identification mediates the relationship between job challenge and employees' creative behavior.     

Knowledge of one's kinematics improves perceptual discrimination

We tested the hypothesis that our ability to detect fine kinematics variations is tuned to reveal more subtle differences when the motion pattern belongs to the observer compared to another individual. To this purpose, we analyzed the responses of 15 subjects in a same-different task on pairs of movements, which could belong to one or two different subjects. Self vs. Other comparisons were obtained by presenting both the observer's and another participant's kinematics. Subjects responded faster and more accurately when they observed their own gestures compared to movements of another participant. In the latter case, slight kinematic differences were more likely to remain undetected. These findings are discussed within an ecological framework: in observing others, we are more concerned with detection of goals and intentions, i.e., outstanding variations in motion patterns. Conversely, in self-observation detection of more subtle differences is required to facilitate learning and optimization of motor acts.     

Approach‐Avoidance Motivation and the Use of Affect as Information

Individuals often rely on their affect for information. However, positive or negative affect may not be informative for individuals who are more prone to feel affect of this particular valence in general, unless they chronically monitor their internal states. A series of studies demonstrates that differences in individuals’ internal versus external focus of attention and in trait affective valence associated with their approach versus avoidance motivation determine reliance on affect as information. Specifically, our findings show that while positive affect is used as an input in product satisfaction judgments regardless of individuals’ approach versus avoidance motivation, negative affect is used only by individuals with a predominant approach motivation.
