Forensic researchers and practitioners continue to face challenges when attempting to differentiate deceptive response styles, notably when comparing malingering and factitious disorder. However, due to the great disparities in research available, forensic examiners may not be adequately informed for considering factitious presentations as a competing hypothesis to malingering. De-emphasis of factitious disorders may also be attributed to the lack of empirical research and poor conceptual understanding of the disorder. Velsor and Rogers conducted a thorough review of various factitious motivations, drawing a parallel to Rogers' explanatory models of malingering. Due to the need for a systematic measure of FPPs, the Inventory of Self and Interpersonal Problems (I-SIP) was developed, largely based on the explanatory models of FPP. The current study employed a construct validity approach to the I-SIP to examine its convergent and discriminant validity in a sample of 80 inpatients from a private psychiatric hospital. Providing strong evidence of construct validity of the I-SIP, dramatic differences emerged between malingered and factitious presentations with extremely large effect sizes (ds = 1.09 – 3.62). In particular, results indicated strong support for the nurturance explanatory model of FPPs, as over-investment in treatment providers was an especially strong discriminator (d = 3.62). Moreover, …

Using a strong invariance structural equation modeling approach, the current study explored the role of parental styles, along with age and IQ, on the expression of psychopathic personality facets in a large (N = 734) male sample of Hispanic and non-Hispanic offenders. Multiple group confirmatory factor analyses revealed evidence of strong invariance across ethnic groups for the psychopathy and parenting scales (CFI = .95; RMSEA .03). Person-centered analyses examining psychopathic versus non-psychopathic cases demonstrated that the former reported greater levels of dysfunctional parenting, particularly abuse. Structural equation modeling results highlighted differential relationships between the variables of interest as a function of race/ethnicity.
