A Comparison of the Nomological Networks Associated With Forced-Choice and Likert Formats of the Narcissistic Personality Inventory

The Narcissistic Personality Inventory (NPI) is one of the most popular measures of narcissism. However, its use of a forced-choice response set might negatively affect some of its psychometric properties. The purpose of this research was to compare a Likert version of the NPI, in which only the narcissistic response of each pair was given, to the original NPI, in 3 samples of participants (N = 1,109). To this end, we compared the nomological networks of the forced-choice and Likert formats of the NPI in relation to alternative measures of narcissism, narcissistic personality disorder, entitlement, self-esteem, general personality traits (reported by self and informants), interpersonal styles, and general pathological traits included in the DSM–5. The Likert format NPI—total and subscales—manifested similar construct validity to the original forced-choice format across all criteria with only minor differences that seem to be due mainly to the increased reliability and variability found in the Likert NPI Entitlement/Exploitativeness subscale. These results provide evidence that a version of the NPI that employs a Likert format can justifiably be used in place of the original.     

Computer-Guided Problem-Solving Treatment for Depression,PTSD, and Insomnia Symptoms in Student Veterans: A Pilot Randomized Controlled Trial

Depression is a highly prevalent psychological disorder experienced disproportionately by college student military veterans with many deleterious effects including risk for suicide. Treatment can help, but the debilitating nature of depression often makes seeking in-person treatment difficult and many are deterred by stigma, inconvenience, concerns about privacy, or a preference to manage problems themselves. The current study examines the efficacy of a computer-guided Problem-Solving Treatment (ePST^®) for reducing symptoms of depression, posttraumatic stress disorder (PTSD), and insomnia in student military veterans. Twenty-four student veterans (Mean_age = 32.7) with symptoms of depression were randomly assigned either to a treatment group receiving six weekly sessions of ePST or to a minimal contact control group (MCC). Participants completed the Patient Health Questionnaire-9 (PHQ-9) depression scale at baseline and then weekly through post-ePST or post-MCC. PTSD and insomnia questionnaires were also completed at baseline and posttreatment. A linear mixed model regression showed a statistically significant Group (ePST vs. MCC) × Time (pretreatment through posttreatment) interaction for depression, with the ePST showing substantial improvements in depressive symptoms over the 6-week period. Significant improvements were also seen in PTSD and insomnia symptoms. Results suggest that ePST can effectively treat depression, PTSD, and insomnia symptoms in student military veterans and may be a viable alternative for those who are not able to access live therapy. Future work should examine the durability of treatment effects and utility for more severe depression and suicide prevention.     

Power Evangelism in a Protestant Context? Reflections after a Workshop in Samosir/Indonesia

This article discusses how the neo‐Pentecostal concept of power evangelism, read from a liberation perspective, might be useful to contextualize evangelism in the Toba Batak region of Samosir. In a situation where evangelistic preaching follows an evangelical forensic paradigm but Christians turn to traditional religious rituals for blessing, healing, and protection, a new approach is needed. Preaching and liturgies informed by a power paradigm might resolve the problem of syncretism, but important theological questions need to be clarified.     

Increasing correct participation in an exercise class for adult day care clients

Facilities which provide services to the elderly offer a wide variety of activities to engage their clients. In many cases, however, clients do not participate in these activities, or they do not participate in ways which are likely to provide them with benefits. This study sought to increase meaningful participation in an exercise class by four elderly clients attending an adult day care program; in these four cases, the quality of their participation was seriously inadequate. Participants were praised when they participated correctly in an exercise, verbally prompted if they did not participate, and physically assisted to participate if they did not participate following verbal prompting. To show experimental control over exercise behaviors, a single subject multiple baseline design was used. The results suggest that clients attending facilities such as an adult day care program may be easily recruited to participate correctly in exercise sessions through the use of prompts and social reinforcers.

Instrumental and expressive representations of aggression: One scale or two?

The Expagg questionnaire was developed to measure a subject's view of their own aggression as a relatively instrumental or relatively expressive act. Two issues have been raised pertaining to the dimensional structure of the questionnaire: the use of principal components analysis on dichotomous responses and the possibility that instrumental and expressive representations might be independent dimensions rather than opposite ends of a single continuum. In study 1, dichotomous Expagg data from 405 subjects were subjected to microfact, principal components, and factor analysis. Each produced a first general factor, and the correlations between the item loadings were in excess of r = .99. In study 2, a 40‐item Likert scale version of Expagg was given to 295 subjects. Principal components analysis, paired item correlations, and subscale correlations suggested partial independence of instrumental and expressive items. Two new 8‐item scales measuring instrumental and expressive representations were constructed that maximise their independence. Potential uses of these revised scales are discussed. Aggr.

On the role of stimulus preference assessment in the evaluation of contingent access to stimuli associated with stereotypy during behavioral acquisition

Previous authors have reported successful behavioral acquisition in children diagnosed with autism using contingent access to stereotypic responding as reinforcement. Other studies have demonstrated robust reinforcement effects when consequences were selected using stimulus preference assessments. We conducted two stimulus preference assessments with a six-year-old female diagnosed with autism. Her acquisition of a non-vocal imitation response was then evaluated during two reinforcement conditions: contingent access to (i) a stimulus associated with stereotypic object manipulation and (ii) a stimulus unassociated with such stereotypy. Both stimuli were identified from the stimulus preference assessments. Nearly identical response patterns were observed in both conditions; correct responses to verbal prompts greatly increased while correct responses to gestural and physical prompts decreased to near-zero levels. These preliminary findings are discussed in the context of improving stimulus selection in this area. © 1998 John Wiley & Sons, Ltd.     

Aggression and testosterone: Testing a bio-social model

Based upon reports of a positive correlation between circulating testosterone levels and aggression, we draw upon evolutionary psychology to place the action of testosterone in a broader perspective. We propose that testosterone affects competitive status-seeking and that under certain circumstances (including youth) this is expressed as aggression. Involvement in aggression in turn is associated with adherence to an instrumental social representation of aggression which justifies aggression as a means of imposing control over others and increasing self-esteem. Measures of salivary testosterone, masculinity, preferred social representation of aggression, and multiple aggression scales were collected from an undergraduate sample of 119 men. An Aggression factor was derived from principle components analysis of the aggression measures. The strongest correlates of Aggression were holding an instrumental social representation of aggression and youth. Testosterone showed no significant relationship to the single or aggregate measures of aggression or to any of the other psychometric measures. We suggest ways in which previous work may have over-estimated the strength of the association between circulating testosterone and aggression and discuss the possible relationships between age, social representation, and aggression.

Mapping Residents' Perceptions of Neighborhood Boundaries: A Methodological Note

Neighborhood influences on children and youth are the subjects of increasing numbers of studies, but there is concern that these investigations may be biased, because they typically rely on census-based units as proxies for neighborhoods. This pilot study tested several methods of defining neighborhood units based on maps drawn by residents, and compared the results with census definitions of neighborhoods. When residents' maps were used to create neighborhood boundary definitions, the resulting units covered different space and produced different social indicator values than did census-defined units. Residents' agreement about their neighborhoods' boundaries differed among the neighborhoods studied. This pilot study suggests that discrepancies between researcher and resident-defined neighborhoods are a possible source of bias in studies of neighborhood effects.     

Thought-action fusion and anxiety disorders symptoms in normal adolescents.

The present study examined thought-action fusion (TAF) in a large sample of normal adolescents (n=427). Participants completed the Thought-Action Fusion Questionnaire for Adolescents (TAFQ-A) and scales measuring trait anxiety, symptoms of obsessive-compulsive disorder, other anxiety disorders, and depression. Results showed that the TAFQ-A is a reliable instrument assessing two dimensions of TAF, viz. Morality (i.e., the belief that unacceptable thoughts are morally equivalent to overt actions) and Likelihood (i.e., the belief that thinking of an unacceptable or disturbing situation will increase the probability that that situation actually occurs). Furthermore, TAF was not only associated with symptoms of OCD, but also with symptoms of other anxiety disorders and depression. However, when controlling for levels of trait anxiety, most connections between TAF and anxiety disorders symptoms disappeared. Symptoms of OCD and generalised anxiety remained significantly related to TAF. Altogether, the data are supportive of the notion that TAF is involved in a broad range of anxiety disorders and in particular OCD.
