Psychometric properties of the Montreal Cognitive Assessment (MoCA) in inpatient liver transplant candidates.

Hepatic encephalopathy (HE) is a consequence of liver disease and often diagnosed via psychometric testing. With inpatients, the Montreal Cognitive Assessment (MoCA) may be used as part of cognitive screening for transplant candidacy. However, the MoCA was developed to detect mild cognitive impairment in aging populations and its psychometric properties in inpatients with liver disease have not been determined.

Identifying Careless Responding With the Psychopathic Personality Inventory-Revised Validity Scales.

The Psychopathic Personality Inventory-Revised (PPI-R) includes validity scales that assess Deviant Responding (DR), Virtuous Responding, and Inconsistent Responding. We examined the utility of these scales for identifying careless responding using data from two online studies that examined correlates of psychopathy in college students (Sample 1: N = 583; Sample 2: N = 454). Compared with those below the cut scores, those above the cut on the DR scale yielded consistently lower validity coefficients when PPI-R scores were correlated with corresponding scales from the Triarchic Psychopathy Measure.

Is the Dodo bird endangered in the 21st century? A meta-analysis of treatment comparison studies.

The Dodo bird hypothesis asserts that when bona fide treatments are compared they yield similar outcomes and this hypothesis is consistent with a common factors or contextual model of psychotherapy. Wampold et al. (1997), the most recent comprehensive meta-analysis to test the Dodo bird hypothesis, yielded consistent evidence of treatment equivalence.
