The shaping of personality: genes, environments, and chance encounters

I started my career as a clinical psychologist with an interest in personality assessment. But a loss of faith in psychoanalytic theory, projective tests, and clinical case studies in general led to a shift in my interests to personality research. Subsequent jobs at research institutes and universities allowed me to indulge in science. I developed the trait-state concept and its application in tests for affect measurement. For 10 years I did experimental research in the field of sensory deprivation. The sensation seeking idea and tests evolved from this work but soon expanded to many other areas. Research in the biological basis of sensation seeking started with genetic and psychophysiological research, but research conducted in other laboratories also pointed to a psychopharmacological basis for the trait. Over the last several decades, I have formulated a psychobiological model for personality. I have used factor analysis and the biosocial model to develop an "alternative-five" factorial trait structure for personality.     

Risk of false positives when identifying malingered profiles using the trauma symptom inventory

The Trauma Symptom Inventory (TSI; Briere, 1995) is a 100-item self-report measure of posttraumatic symptomatology that includes an Atypical Response (ATR) validity scale designed to differentiate honest from malingered profiles. In this study, using an analogue design to experimentally manipulate honest and malingered responses on the TSI, we found that proposed ATR cut scores produce a significant risk of false positives. Furthermore, the functioning of proposed cut scores worsened when we used posttraumatic stress disorder relevant samples and low estimates of malingering base rates. In light of these findings, the TSI should be used with caution when assessing claims of posttraumatic stress in forensic or disability settings.     

Family secrecy: a comparative study of juvenile sex offenders and youth with conduct disorders

The reported research was designed to compare adjudicated male juvenile sexual offenders and youth with conduct disorders on five aspects of family secrecy and deception. Twenty-nine male juvenile sex offenders and 32 comparison youth from three child welfare agencies in New York State participated in the study. Research assistants, blind to the hypotheses of the study and status of the youth, coded agency records for five variables identified a priori as a basis of comparison. Analyses revealed that the two groups were different on three of the five and on the total number of items scored. Families of juvenile sex offenders told more lies, had more family myths, and were more likely to be involved in taboo behavior. Logistic regression revealed that this factor of family deception significantly increased the odds of sexual offending over and above other measures of family pathology. These data support the hypotheses of the study and have implications for both clinical practice and future research in this area.     

Demythologizing the emotions: adaptation,cognition, and visceral representations of emotion in the nervous system

This article highlights four issues about the neurobiology of emotions: adaptation vs. dysfunction, peripheral and central representations of emotion, the regulation of the internal milieu, and whether emotions are cognitive. It is argued that the emotions evolved to play diverse adaptive roles and are biologically vital sources of information processing. They were not designed as pieces of pathology, though they certainly can underlie some psychophathologies. Emotions are, in part, appraisal systems that are operative at numerous level of the nervous system from the brainstem to the cortex. Like other information processing systems they are not perfect cognitive systems. Emotional systems often utilize somatic and visceral information for appraisals of events to facilitate decisions of whether to approach or avoid objects. The neural systems of emotions traverse the entire neural axis and are linked to the regulation of the internal milieu. Thus, in addition to the experiential aspects of emotions, emotions embody appraisal systems that are pervasive to all levels of the brain to facilitate function, adaptation, and survival.     

Effects of involuntary outpatient commitment on subjective quality of life in persons with severe mental illness

Recent evidence suggests that involuntary outpatient commitment (OPC), when appropriately applied, can improve adherence with psychiatric treatment, decrease hospital recidivism and arrests, and lower the risk of violent behavior in persons with severe mental illness. Presumably these are benefits that improve quality of life (QOL); however, insofar as OPC involves legal coercion, the undesirable aspects of OPC could also exert a negative effect on quality of life, thus offsetting clinical benefits. Involuntarily hospitalized subjects, awaiting discharge under outpatient commitment, were randomly assigned to be released or continue under outpatient commitment in the community after hospital discharge, and were followed for one year. Quality of life was measured at baseline and 12 months follow-up. Treatment characteristics and clinical outcomes were also measured.Subjects who underwent longer periods of outpatient commitment had significantly greater quality of life as measured at the end of the 1 year study. Multivariable analysis showed that the effect of OPC on QOL was mediated by greater treatment adherence and lower symptom scores. However, perceived coercion moderated the effect of OPC on QOL. Involuntary outpatient commitment, when sustained over time, indirectly exerts a positive effect on subjective quality of life for persons with SMI, at least in part by improving treatment adherence and lowering symptomatology.     

Assessment of behavioral and psychological symptoms of dementia

In spite of their prevalence and persistence, why are behavioral and psychological symptoms of dementia difficult for clinicians to assess and manage? This paper provides an overview of the methodological challenges encountered in measuring behavioral disturbances of dementia. Specifically, conceptual constructs of behavioral and psychological symptoms of dementia, the strengths and weaknesses of the currently existing rating instruments, analytic methodologies, and the utility of technological devices are outlined in the service of formulating future directions in behavioral and psychological symptoms of dementia assessment research.     

Comparison of brain activation during word retrieval done silently and aloud using fMRI

Using functional MRI we compared the patterns of activation in an effortful word retrieval task (stem completion) performed both silently and aloud. The silent and overt conditions showed expected differences in activation magnitude in regions such as primary motor cortex. Some regions, such as frontal operculum and dorsolateral frontal cortex, showed similar activation magnitude across conditions. Thalamus was more active on the left in both conditions and showed a symmetric drop in activity in the silent compared with the overt condition. Putamen was also more active in the overt condition and showed a larger decrease in activity on the right than on the left in the silent compared with the overt condition. Thus it appears that silent and overt performance of this task engage the thalamus and putamen in different ways.     

Gone Today but here Tomorrow: Extending the Unfolding Model of Turnover to Consider Boomerang Employees

Turnover research typically views voluntary turnover as an end state that severs the employment relationship permanently. However, this perspective overlooks the possibility that an employee who quits may return in the future. Anecdotal and empirical evidence suggest that these “Boomerangs” can be a valuable staffing resource for their organizations. Yet, research regarding this type of employee is largely absent. Thus, we know little about whether the experiences of these temporary leavers differ from those who leave an organization permanently. In this paper, we examined differences between Boomerangs (employees who quit but are later rehired) and “Alumni” (employees who quit but will not return) using both qualitative and quantitative data. In a large sample of professional service employees, we found that Boomerangs and Alumni reported different reasons for having quit, which meant they were more likely to be classified on different paths in the unfolding model of turnover. In addition, survival analyses on the time to turnover suggest that Boomerangs quit earlier than Alumni in their original tenure, paradoxically suggesting that employees who quit earlier may be the very employees who will return in the future. Together, our findings suggest an extension to the unfolding model that considers how the timing of and reasons for turnover impact post‐turnover (return) decisions.     

Miami Thrives: Weaving a Poverty Reduction Coalition

In an environment where community based organizations are asked to do increasingly more to alleviate the effects of complex social problems, networks and coalitions are becoming the answer for increasing scale, efficiency, coordination, and most importantly, social impact. This paper highlights the formation of a poverty reduction coalition in south Florida. Our case study approach chronicles a developing coalition in Miami-Dade County and the role of one organization acting as lead to the initiative. Drawing on interviews with lead organization staff, participant observation field notes, network mapping and analysis of documents and artifacts from the initiative, we analyze the local organizational context and illuminate important processes associated with supporting a developing coalition. Findings offer a picture of the interorganizational relationships in the community using social network analysis and identify the organizational capacity factors that contribute to and inhibit the formation of a cohesive and effective coalition in this context. This study also highlights the utility of an action research approach to organizational learning about coalition-building in such a way that informs decision making.     

Assessing Changes in Counselor Trainees' Multicultural Competence Related to Service Learning

This mixed methods study examined changes in self‐reported multicultural competence and distress reactions of 32 counselor trainees engaged in service learning. Whereas 3 trainees significantly increased in self‐reported multicultural competence, 5 significantly decreased. Trainees who significantly increased in multicultural competence reported less distress; those who significantly decreased reported greater distress. However, changes in multicultural competence appeared to be unrelated to themes uncovered in the qualitative data. Implications for training and practice are discussed. Este estudio de métodos mixtos examinó los cambios en competencia cultural y reacciones de aflicción reportados por 32 consejeros en formación que realizaban prácticas para su aprendizaje. A pesar de que 3 consejeros en formación comunicaron un aumento significativo de su competencia cultural, 5 de ellos reportaron una disminución significativa. Los consejeros en formación que aumentaron considerablemente su competencia cultural reportaron un nivel menor de aflicción; aquellos que disminuyeron considerablemente reportaron mayor aflicción. Sin embargo, los cambios en la competencia cultural no tenían relación aparente con los temas desvelados en los datos cualitativos. Se discuten las implicaciones para la formación y prácticas.
