Influences on responsiveness: Interactions between mothers and their premature infants

The responsiveness of mothers to their infants has been found to make an important contribution to children's development. Mothers' cognitive ability, emotional state, and life stresses may influence their responsiveness, as may the medical condition of their infants. The patterns of influence may vary between groups of children with different biological risk conditions and should be examined carefully to determine intervention points for different groups. Forty mothers and their 3-month-old (corrected age) infants with intraventricular hemorrhage (IVH) were observed in free play. Mothers' depressive symptoms, cognitive skills, and the degree of infants' IVH were assessed and expected to be influences on mothers' responsiveness. Results indicated that mothers' depressive symptoms and cognitive skills were associated with their responsiveness, but that depressive symptoms were the stronger predictor. Post hoc analyses suggested that socioeconomic status and depressive symptoms may have related effects on mothers' behavior.

A Statistical Consideration Regarding the Threshold of the Psychopathy Checklist–Revised

The Psychopathy Checklist–Revised (PCL–R; Hare, 2003 Hare, R. D. (2003). Hare Psychopathy Checklist–Revised technical manual (2nd ed.). Toronto, ON, Canada: Multi-Health Systems. [Google Scholar]) is one of the most commonly used measures of psychopathy. Scores range from 0 to 40, and legal and mental health professionals sometimes rely on a cut score or threshold to classify individuals as psychopaths. This practice, among other things, assumes that all items contribute equally to the overall raw score. Results from an item response theory analysis (Bolt, Hare, Vitale, &; Newman, 2004 Bolt, D. M., Hare, R. D., Vitale, J. E., &; Newman, J. P. (2004). A multigroup item response theory analysis of the Psychopathy Checklist–Revised. Psychological Assessment, 16, 155–168. doi:10.1037/1040-3590.16.2.155[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), however, indicate that PCL–R items differ in the amount of information they can provide about psychopathy. We examined the consequences of these item differences for using a cut score, detailing the consequences for a previously applied cut score of 30 as an example. Results indicated that there were more than 8.5 million different response combinations that equaled 30 and more than 14.2 million that equaled 30 or more. This raw score, like others, corresponded to a broad range of PCL–R-defined psychopathy, indicating that applying cut scores on this measure results in imprecise quantifications of psychopathy. We show that by using the item parameters along with an individual's particular scores on the PCL–R items, it is possible to arrive at a more precise understanding of an individual's level of psychopathy on this instrument.
