The precise operational definition of psychosis in dementia lacks consensus, partially owing to incongruence in the various assessment tools used. This study compares assessments of psychotic symptoms in persons with dementia, specifically of hallucinations and delusions, through the 4 most frequently used assessments. Participants were 74 nursing home residents from 9 nursing homes in Israel, ...

OBJECTIVE To identify regional brain metabolic dysfunctions associated with neuropsychiatric symptoms (NPS) in preclinical Alzheimer disease (AD). METHODS We stratified 115 cognitively normal individuals into preclinical AD (both amyloid and tau pathologies present), asymptomatic at risk for AD (either amyloid or tau pathology present), or healthy controls (no amyloid or tau pathology present...

Narcissism is associated with morally questionable behavior in the workplace, but little is known about the role of specific dimensions of narcissism or the mechanism behind these effects. The current study assessed academic dishonesty among college students. One hundred and ninety-nine participants either self-reported or reported others’ cheating behavior and completed the Narcissistic Person...

Lack of a suitable measuring device hampered the empirical study of narcissism until Raskin and Hall (1979) developed the Narcissistic Personality Inventory (NPI). The NPI possesses desirable psychometric properties, and in this article I used the scale in a variety of studies. Factor analysis of the scale replicated the four-factor solution found by Emmons (1984): Leadership/Authority, Self-Ab...

There is a lack of consensus surrounding the conceptualization of narcissism. The present study compared two measures of narcissism-one used in clinical settings (Personality Diagnostic Questionnaire, PDQ-4+; Hyler, 1994) and one used in social-personality research (Narcissistic Personality Inventory, NPI; Raskin & Terry, 1988)-across two samples. Sample 1 (N=271) was composed of undergraduates...

Narcissistic Personality Inventory (NPI; Emmons, 1984) factors were correlated with Splitting, Self-Consciousness, Depression, Anxiety, and Self-Esteem. Exploitativeness/Entitlement was largely maladaptive, whereas Leadership/Authority, Superiority/Arrogance, and Self-Absorption/Self-Admiration yielded ambiguous outcomes. Partialing out Exploitativeness/Entitlement uncovered stronger ties of th...

Background: Neuropsychiatric symptoms in patients with frontotemporal dementia (FTD) are highly prevalent and may complicate clinical managements. Objective: We tested whether the Neuropsychiatry Inventory (NPI) could detect change neuropsychiatric caregiver´s distress diagnosed behavioral variant (bvFTD) Alzheimer’s disease (AD) from baseline to a 12-month follow-up. Methods: The sample consis...

This study examines the effect of amantadine on irritability in persons in the post-acute period after traumatic brain injury (TBI). There were 168 persons ≥6 months post-TBI with irritability who were enrolled in a parallel-group, randomized, double-blind, placebo-controlled trial receiving either amantadine 100 mg twice daily or equivalent placebo for 60 days. Subjects were assessed at baseli...

Methods. 88 subjects and their family caregivers recruited from memory and psychogeriatric clinics were assessed using the Clinical Dementia Rating scale (CDR), the Barthel Index (BI), the Mini-Mental States Examination (MMSE), the Neuropsychiatric Inventory (NPI), the Disability Assessment for Dementia (DAD) scale, the Geriatrics Depression Scale (GDS), and the Zarit Burden Interview. Correlat...

Influential social and personality psychology research indicates that narcissism is related to psychological health. Such inferences are open to question, however, because they nearly all rely on the same selfreport instrument—the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979, 1981)—to operationalize and measure narcissism. This is problematic because numerous NPI items do not ap...
