With the introduction in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) of a hybrid system of personality disorder assessment, the ability to assess patients' traits, as well as their level of personality functioning, has become increasingly important. To assess this criterion, the DSM-5 Levels of Personality Functioning Questionnaire (DLOPFQ) was developed. The DLOPFQ assesses individuals' self-impairments and other impairments in several domains (self-direction, identity, empathy, and intimacy) and across 2 contexts (work/school and relationships). A sample of 140 psychiatric and medical outpatients was administered the DLOPFQ and several other measures to assess its reliability and construct, incremental, and discriminant validity. The internal consistency and convergence with validation measures yielded generally meaningful and expected results. Several DLOPFQ scales and subscales were significantly correlated with measures of DSM-5 trait domains and levels of personality functioning. DLOPFQ scales also correlated with self-reported ratings of overdependence, detachment, healthy dependency, and overall mental health and well-being. The DLOPFQ also predicted interpersonal and general functioning beyond DSM-5 trait domains. These results support the reliability and validity of the DLOPFQ, which appears to be suitable for clinical use and warrants ongoing study.

A current trend emphasizes simplified models of traits and personality functioning that would reduce individuals to as few as five potential traits and one dimension of personality functioning. However, the evidence behind those models is based on linear methods of analysis that authors from Cattell to Kernberg (2016) believe do not capture the potential moderating interaction effects of personality. Using models of traits and functioning from the DSM-5, this study demonstrates not only that traits and functioning interact, but that they do so in a rich and meaningful way that points up the dangers of collapsing these concepts. Without taking the interaction into account, satisfaction in romantic or work relationships often could not be predicted or understood. If we cannot predict satisfaction in these relationships with precision, honest confusion arises over how to guide others toward these goals. Low Detachment depends on high levels of Self-Definition, just as low Antagonism relies on high levels of Empathy to be successful. Most interestingly, negative traits and low functioning can actually lead to individual satisfaction, suggesting not only that interaction is key but that nonlinear effects may also be present.
The Instruments for Assessing Understanding and Appreciation of Miranda Rights, hereafter referred to as the Grisso tests, are widely used and recommended psychological tests designed to help assess ability to understand and appreciate Miranda warnings. This article describes the results of these tests administered to 439 individuals who participated in an evaluation to assess knowing and intelligent waiver of Miranda warnings during police questioning. This study is the first of its kind using a large sample of defendants who were referred for an assessment of capacity to waive Miranda rights. This forensic sample includes both juveniles (176) and adults (263), and the results are quite similar to the original Grisso norms. There are strong correlations between performance on these tests and IQ as well as between performance and age. This sample provides a broader foundation for users of the Grisso tests and answers some of the initial criticism of the instruments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
