Severity Indices of Personality Problems (SIPP-118) in adolescents: reliability and validity

The Severity Indices of Personality Problems (SIPP-118; Verheul et al., 2008) is a self-report questionnaire focusing on core components of (mal)adaptive personality functioning. The SIPP-118 was developed and validated in an adult population. In adult populations, the 16 facets of the SIPP-118 fit into 5 higher order domains: self-control, identity integration, relational capacities, social concordance, and responsibility. In this study we present the 1st psychometric properties of the SIPP-118 in adolescents. We compared the SIPP-118 scores of a patient and a nonpatient sample of adolescents, and compared personality disordered and non-personality disordered adolescents. In addition, the relationship between scores on the SIPP-118 and other clinical instruments (Symptom Checklist-90-Revised; SCL-90-R; Derogatis, 1975; Dimensional Assessment of Personality Pathology-Basic Personality; DAPP-BQ; Livesley & Jackson, 2002) was investigated. The questionnaires were completed by 378 adolescent patients and 389 adolescents in the community. Facets appeared to be homogeneous, as alpha coefficients ranged from .62 to .89, indicating moderate to acceptable reliability. Also, more pathological SIPP-118 scores were found in the patient sample, and more specifically in the personality disordered sample, suggesting that the facet scores of the SIPP-118 can discriminate between various populations (divergent validity). Correlation with other clinical instruments was moderate to high (-.82 to .10). Taken together, the SIPP-118 seems to be a promising instrument measuring personality pathology in adolescents.     

Comfort constrains graphic workspace: Test results of a 3D forearm model

Human movement performance is subject to many physical and psychological constraints. Analyses of these constraints may not only improve our understanding of the performance aspects that subjects need to keep under continuous control, but may also shed light on the possible origins of specific behavioral preferences that people display in motor tasks. The goal of the present paper is to make an empirical contribution here. In a recent simulation study, we reported effects of pen-grip and forearm-posture constraints on the spatial characteristics of the pen tip's workspace in drawing. The effects concerned changes in the location, size, and orientation of the reachable part of the writing plane, as well as variations in the computed degree of comfort in the hand and finger postures required to reach the various parts of this area. The present study is aimed at empirically evaluating to what extent these effects influence subjects' graphic behavior in a simple, free line-drawing task. The task involved the production of small back-and-forth drawing movements in various directions, to be chosen randomly under three forearm-posture and five pen-grip conditions. The observed variations in the subjects' choice of starting positions showed a high level of agreement with those of the simulated graphic-area locations, showing that biomechanically defined comfort of starting postures is indeed a determinant of the selection of starting points. Furthermore, between-condition rotations in the frequency distributions of the realized stroke directions corresponded to the simulation results, which again confirms the importance of comfort in directional preferences. It is concluded that postural rather than spatial constraints primarily affect subjects' preferences for starting positions and stroke directions in graphic motor performance. The relevance of the present modelling approach and its results for the broader field of complex motor behavior, including the manipulation of tools, is indicated briefly.

Should subjects be forewarned of the possible psychological consequences of filling out a PTSD questionnaire?

In 1993 Albach investigated the long-term consequences of sexual abuse on psychological health. A group of abused women a a control group of nonabused women were asked to fill in a questionnaire assessing posttraumatic stress disorder (PTSD). For ethical reasons, the abused women were warned that filling in the questionnaire might be emotionally stressful. The control group did not receive this warning. The abused women scored higher on the questionnaire than the nonabused women. The warning they received may have influenced their reports. Our experiment investigated this. 101 psychology students were divided into two groups, one who received a warning and a control group who did not. The hypothesis was that people who had been previously warned would score higher on a PTSD questionaire than people who had not. There were, however, no significant differences in mean PTSD scores and no known initial differences between groups.     

Charismatic leadership,environmental dynamism,and performance

Most studies relating charismatic leadership to performance have limitations concerning selection of criterion measures and investigation of moderators. Therefore, this study examines relationships between charismatic leadership and multiple performance outcomes under different levels of environmental dynamism (i.e., level of environmental uncertainty, degree of technological change) and per type of Chief Executive Officer (firm owner versus managing director). Results revealed that charismatic leadership was positively related to common-source and multi-source perceptual performance outcomes (i.e., subordinates' positive work attitude) and to organization profitability, but unrelated to organization liquidity and solvency. The relationship between charismatic leadership and perceptual performance was stronger under conditions of environmental uncertainty than under conditions of environmental certainty. Furthermore, charismatic leadership was more strongly related to organization profitability for firm owners than for managing directors who do not own their firm. The results are discussed and several potentially fruitful avenues for future research on charismatic leadership and employee as well as organizational performance are presented.     

How Do Perceptions of God as Autonomy Supportive or Controlling Relate to Individuals' Social-Cognitive Processing of Religious Contents? The Role of Motives for Religious Behavior

Using self-determination theory as a guiding framework, this study examined whether perceptions of God as autonomy supportive and controlling were related to individuals' belief in a transcendent reality and to their social-cognitive style of approaching religious contents (i.e., literal and rigid vs. symbolic and flexible). Further, we examined whether individuals' motives for religious behavior (i.e., autonomous vs. controlled) would mediate these associations. In a sample of 267 religiously active participants, we found that the two types of perceptions of God were positively related to belief in transcendence but were differentially related to a symbolic approach. Specifically, a perception of God as autonomy supportive related positively and a perception of God as controlling related negatively to a symbolic approach. Some evidence was obtained for a mediating role of motives for religious behavior in these associations. Discussion focuses on how self-determination theory can contribute to research on the psychology of religion.     

Why Narcissists are Unwilling to Apologize: The Role of Empathy and Guilt

We hypothesized that narcissists would be unwilling to apologize for their interpersonal transgressions, and that reduced levels of self‐reported empathy and guilt would serially mediate this effect. Narcissism is characterized by little empathy for the victim, which reduces guilt about one's transgressions. Low guilt, in turn, is associated with unwillingness to apologize. In Study 1, we assessed dispositional narcissism, empathy, guilt, and willingness to apologize. In Study 2, we assessed dispositional narcissism and obtained state measures of empathy, guilt, and willingness to apologize. In Study 3, we manipulated narcissism and collected state measures of empathy, guilt, and willingness to apologize. Narcissism was negatively associated with (Studies 1–2) and decreased (Study 3) willingness to apologize, with this link being explained (i.e., serially mediated) by low empathy and guilt. Finally, in Study 4, we showed that antagonistic narcissism (i.e., narcissistic rivalry), but not agentic narcissism (i.e., narcissistic admiration), was negatively associated with willingness to apologize and apologizing behaviour. In all, narcissists are unwilling to apologize for their transgressions, as they experience little empathy for their victims and lower guilt.

Constructing bootstrap confidence intervals for principal component loadings in the presence of missing data: a multiple-imputation approach

Earlier research has shown that bootstrap confidence intervals from principal component loadings give a good coverage of the population loadings. However, this only applies to complete data. When data are incomplete, missing data have to be handled before analysing the data. Multiple imputation may be used for this purpose. The question is how bootstrap confidence intervals for principal component loadings should be corrected for multiply imputed data. In this paper, several solutions are proposed. Simulations show that the proposed corrections for multiply imputed data give a good coverage of the population loadings in various situations.     

Factors associated with parenting among incarcerated juvenile offenders

In regard to the injured offender, research indicates that violent victimization represents only one facet of a constellation of associated risks and consequences, including promiscuity and adolescent parenthood. A relationship between firearm injuries and self-reported promiscuity among incarcerated juvenile offenders has previously been noted. The present study was an attempt to gain additional insight into the larger consequences of violent injuries. Information pertaining to the fathering of children was collected from 258 incarcerated male adolescents from the Richmond, Virginia, metropolitan area during a two-year period. It was hypothesized that adolescent parenting would be associated with firearm injuries. The results indicated that 20% of the juvenile offenders fathered at least one child. Analyses revealed a significant relationship between firearm injuries and increased prevalence of adolescent parenting. Continued involvement in illegal activities, as indicated by a second commitment to a juvenile correctional center, also was associated with increased prevalence of adolescent parenting, while race and involvement in drug selling or violent offending were not. The social and economic implications of these findings, particularly in terms of the health care and social service delivery systems, are discussed.
