Evaluation Of The Hare-Pscan In A Non-Clinical Population, Cristal Elwood, Norman Poythress, Kevin Douglas

Using 100 university undergraduates as participants, this study examined the structural reliability and construct validity of Hare and Hervé's P-SCAN (Hare & Hervé, 1999) a 90-item measure that purports to serve as an “… early warning system” or “rough screening device” (p. 1) for identifying individuals with substantial psychopathic features. Internal consistency indices (e.g. Cronbach's α, mean inter-item correlations) for the three P-SCAN subscales (Interpersonal, Affective, Lifestyle) suggested excellent reliability. Statistically significant, though modest correlations (range 0.21–0.33) were obtained in 5 of 6 comparisons with the self-report Primary psychopathy and Secondary psychopathy scales developed by Levenson, Kiehl, and Fitzpatrick (1995) …
Frontal Alpha Asymmetry As A Pathway To Behavioural Withdrawal In Depression: Research Findings And Issues, Emmanuel Jesulola, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Peter Wilson
Frontal Alpha Asymmetry As A Pathway To Behavioural Withdrawal In Depression: Research Findings And Issues, Emmanuel Jesulola, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Peter Wilson
Vicki Bitsika
Depression has been described as a process of behavioural withdrawal from overwhelming aversive stressors, and which manifests itself in the diagnostic symptomatology for Major Depressive Disorder (MDD). The underlying neurobiological pathways to that behavioural withdrawal are suggested to include greater activation in the right vs the left frontal lobes, described as frontal EEG asymmetry. However, despite a previous meta-analysis that provided overall support for this EEG asymmetry hypothesis, inconsistencies and several methodological confounds exist. The current review examines the literature on this issue, identifies inconsistencies in findings and discusses several key research issues that require addressing for this field to …
Variation In The Profile Of Anxiety Disorders In Boys With An Asd According To Method And Source Of Assessment, Vicki Bitsika, Christopher Sharpley
Variation In The Profile Of Anxiety Disorders In Boys With An Asd According To Method And Source Of Assessment, Vicki Bitsika, Christopher Sharpley

To determine any variation that might occur due to the type of assessment and source used to assess them, the prevalence of 7 anxiety disorders were investigated in a sample of 140 boys with an Autism spectrum disorder (ASD) and 50 non-ASD (NASD) boys via the Child and Adolescent Symptom Inventory and the KIDSCID Clinical Interview. Boys with an ASD were significantly more anxious than their NASD peers. Data collected from the boys with an ASD themselves showed differences in the severity and diagnostic criterion of anxiety disorders to data collected from the boys’ parents. There were age-related variations to …
