Validity of the Modified Child Psychopathy Scale for Juvenile Justice Center Residents

Adult psychopathy has proven to be an important clinical and forensic construct, but much less is known about juvenile psychopathy. In the present study, we examined the construct validity of the self report modified Child Psychopathy Scale mCPS; Lynam (Psychological Bulletin 120:(2), 209–234, 1997) in a sample of 57 adolescents residing in a Dutch juvenile justice center, aged between 13 and 22 years. The mCPS total score was reliably related to high externalizing problems, low empathy, high anger and aggression, high impulsivity, high (violent) delinquency, and high alcohol/drug use. Unique relations were found for the antisocial-impulsive (mCPS Factor 2), but not the callous-unemotional facet of psychopathy (mCPS Factor 1). Our findings support the validity of the mCPS in that it encompasses the antisocial-impulsive facet of psychopathy, but it is less clear whether the mCPS sufficiently captures the affective-interpersonal facet of psychopathy

Differentiating between children's true and false memories using Reality Monitoring criteria

The present study examined the efficacy of the reality monitoring (RM) criteria in differentiating between children's true and false memories. Two independent judges rated 190 transcripts of children's true and false memory reports along the RM criteria. Results showed that, overall, the RM criteria failed to distinguish between children's accounts of true and false events. However, when examining each RM criterion separately, we found that more visual details were present in children's true memories than in their false memories. Results also showed that more RM criteria were present at the second interview than at the first interview

Early maladaptive schemas and their relation to personality disorders: a correlational examination in a clinical population

Personality Disorder (PD) pathology has been linked to Early Maladaptive Schemas (EMSs; Young, 1999). Because of a large heterogeneity in study populations, sample size, statistical analyses and conceptualizations in the literature, the exact relationships between PDs and EMSs are still unclear. The current study examined the relationship between borderline, dependent, avoidant and obsessive-compulsive PDs, represented dimensionally as number of traits, and 15 different EMSs as measured by the YSQ. A total of N = 130 inpatients took part in the study (Mage = 43.6, gender = 51.5% female). Stepwise regressions indicated that borderline, dependent, avoidant and obsessive-compulsive PD traits were partly characterized by specific EMSs and EMSs grouped as domains (i.e. other-directedness domain for dependent PD and overvigilance for obsessive-compulsive PD), and that relations with a variety of domains and EMSs were overlapping for the PD dimensions (i.e. disconnection and rejection for both borderline and avoidant PD). This suggests that PDs are reflected by a hybrid model of EMSs, with some EMSs and domains that relate to a broader vulnerability factor for PDs, and other domains that differentially relate to the independent PDs. Findings are informative for clinicians, as various EMSs per PD may be targeted in therapy

Valence and the development of immediate and long-term false memory illusions

Across five experiments we examined the role of valence in children's and adults’ true and false memories. Using the Deese/Roediger-McDermott paradigm and either neutral or negative-emotional lists, both adults’ (Experiment 1) and children's (Experiment 2) true recall and recognition was better for neutral than negative items, and although false recall was also higher for neutral items, false recognition was higher for negative items. The last three experiments examined adults’ (Experiment 3) and children's (Experiments 4 and 5) 1-week long-term recognition of neutral and negative-emotional information. The results replicated the immediate recall and recognition findings from the first two experiments. More important, these experiments showed that although true recognition decreased over the 1-week interval, false recognition of neutral items remained unchanged whereas false recognition of negative-emotional items increased. These findings are discussed in terms of theories of emotion and memory as well as their forensic implications
