Incremental validity of the MMPI-2 PSY-5 scales in assessing self-reported personality disorder criteria

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Personality Psychopathology-Five (PSY-5) scales were developed to measure abnormal personality symptomatology. The present study examines the incremental validity of the PSY-5 scales beyond the clinical and content scales in assessing criteria associated with personality disorders. The current sample includes 240 male and 407 female clients from private practice settings who completed the MMPI-2 and the Multiaxial Diagnostic Inventory (MDI), a self-report checklist of Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised) symptoms. Six of the MDI personality disorder scales, conceptually related to the PSY-5 scales, are used as criteria. Hierarchical regression analyses determine the incremental validity of each PSY-5 scale. In most analyses, PSY-5 scales add a significant increment of variance to the clinical and content scales. Implications of the results are discussed.     

Spatial updating relies on an egocentric representation of space: Effects of the number of objects

Models of spatial updating attempt to explain how representations of spatial relationships between the actor and objects in the environment change as the actor moves. In allocentric models, object locations are encoded in an external reference frame, and only the actor’s position and orientation in that reference frame need to be updated. Thus, spatial updating should be independent of the number of objects in the environment (set size). In egocentric updating models, object locations are encoded relative to the actor, so the location of each object relative to the actor must be updated as the actor moves. Thus, spatial updating efficiency should depend on set size. We examined which model better accounts for human spatial updating by having people reconstruct the locations of varying numbers of virtual objects either from the original study position or from a changed viewing position. In consistency with the egocentric updating model, object localization following a viewpoint change was affected by the number of objects in the environment.     

The role of self-efficacy in performing emotion work

This study used a sample of 154 cabin attendants to examine the role of self-efficacy in the performance of emotion work. On the basis of the literature, we hypothesized that self-efficacy would have a moderating influence on the relationship between emotional job demands (i.e., feeling rules and emotionally charged interactions with passengers) and emotional dissonance, and on the relationship between emotional dissonance and well-being (emotional exhaustion and work engagement). In addition, we predicted that emotional dissonance mediates the relationship between emotional job demands and well-being. The results of a series of hierarchical multiple regression analyses generally supported these hypotheses. Results confirmed that emotionally charged interactions with passengers are related to emotional exhaustion and engagement through their influence on emotional dissonance. Furthermore, self-efficacy buffers the relationship between emotional job demands and emotional dissonance, and the relationship between emotional dissonance and work engagement (but not exhaustion).     

Treatment for Youth in Short-Term Care Facilities: The Impact of a Comprehensive Behavior Management Intervention

We describe a comprehensive program to train emergency shelter staff in effective methods for dealing with youth who have behavioral and emotional problems; assess the degree to which staff implemented the treatment approach; measure the impact of the intervention on shelter-wide incidents such as out-of-control behavior, runaways, and violence against other youth; and examine pre-post changes in staff experiences at the shelter via anonymous surveys. Overall, the short-term shelter staff indicated adequate implementation of the intervention. The rate of youth incidents at the shelter significantly declined from pre to post assessment. Direct-care staff ratings of their satisfaction with their proficiency in behavior management and teaching youth skills increased significantly from pre to post implementation. These findings suggest that it is feasible to deliver an effective staff-training program to improve the behavior management and social skills of youth residing in short-term care facilities within the child welfare system.
