Itemmetric and scale analysis of a new computer-assisted competency assessment instrument (CADCOMP)

Male defendants (n = 99) who had been court ordered to a forensic treatment facility as incompetent to stand trial were tested using the Computer-Assisted Determination of Competency to Proceed (CADCOMP) instrument soon after admission (median days = 15). Shortly thereafter, competency was assessed by a forensic psychiatrist and by a majority decision of three mental health professionals who viewed a videotape of the forensic psychiatrist's interview. From the CADCOMP item pool, 18 scales were constructed on conceptual grounds. Internal consistency analyses revealed that most scales had reasonable item homogeneity and scale reliability. In addition, item and scale analyses, with few exceptions, followed predicted patterns of intercorrelation and association with competency as determined by both criteria. Scales and items measuring serious psychopathology, psycholegal ability, and criminal history demonstrated the strongest associations with competency. These findings suggest that additional research on CADCOMP is warranted. The instrument shows promise for use in forensic research and assessment.     

Integrating Exposure and Response Prevention With a Mobile App to Treat Obsessive-Compulsive Disorder: Feasibility,Acceptability, and Preliminary Effects

Many individuals with obsessive-compulsive disorder (OCD) do not receive evidence-based care (specifically exposure and ritual prevention; EX/RP) due to barriers such as a lack of EX/RP-trained clinicians, geographic obstacles, and the cost and time associated with the treatment. Offering an integrated treatment model consisting of brief in-person therapy coupled with a mobile application (app) might be one way to increase access to and reduce the time burden (to clinicians and patients) of EX/RP. This pilot trial evaluated the feasibility, acceptability, and clinical effects of such a treatment program for adults with OCD. Thirty-three participants enrolled in the 8-week open trial. The integrated treatment program consisted of 3 to 5 in-person sessions followed by weekly phone calls supported by a mobile app (nOCD). Participants were evaluated by trained raters and completed self-report measures at baseline, midtreatment, posttreatment and 2-month follow-up; the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was the primary outcome. This integrated treatment program was feasible and acceptable to participants. Of the 33 study entrants, 14 (42%) responded to treatment (Y-BOCS decrease ≥ 35% with CGI- of 1 or 2), and 8 (24%) achieved minimal symptoms (i.e., Y-BOCS ≤ 12). At 2-month follow-up (n = 20), 7/20 (35%) met criteria for treatment response, and 3/20 (15.0%) met criteria for treatment remission. Although preliminary, this model warrants further study as an efficacious and resource-efficient way to deliver EX/RP for some patients with OCD.     

Attitudes Toward Abortion in a Sample of South African Female University Students

This study examines the structure of abortion attitudes in a sample of 124 full-time female university residence students, the relationship between self-rated religiosity and abortion attitudes, as well as their knowledge of the Choice on Termination of Pregnancy Act passed in South Africa in 1996. The data provide evidence for the existence of an underlying structure of abortion attitudes, which is complex and multifaceted. Almost 76% of the students described themselves as religious to very religious , and a pronounced trend toward pro-life is evident.     

Making psycholinguistics musical: Self-paced reading time evidence for shared processing of linguistic and musical syntax

Linguistic processing, especially syntactic processing, is often considered a hallmark of human cognition; thus, the domain specificity or domain generality of syntactic processing has attracted considerable debate. The present experiments address this issue by simultaneously manipulating syntactic processing demands in language and music. Participants performed self-paced reading of garden path sentences, in which structurally unexpected words cause temporary syntactic processing difficulty. A musical chord accompanied each sentence segment, with the resulting sequence forming a coherent chord progression. When structurally unexpected words were paired with harmonically unexpected chords, participants showed substantially enhanced garden path effects. No such interaction was observed when the critical words violated semantic expectancy or when the critical chords violated timbral expectancy. These results support a prediction of the shared syntactic integration resource hypothesis (Patel, 2003), which suggests that music and language draw on a common pool of limited processing resources for integrating incoming elements into syntactic structures.

Ethnic differences in endorsement of the Protestant work ethic: the role of ethnic identity and perceptions of social class

The authors examined ethnic differences in endorsement of the Protestant work ethic (PWE; M. Weber, 1905) among Black (n = 96) and White (n = 149) college students and tested whether differences in ethnic identity and perceptions of social class mediated the relationship between ethnicity and the endorsement of PWE values. Blacks were higher in levels of ethnic identity, more likely to see themselves as working or middle class, and less likely to endorse the PWE. Only perceptions of social class partially mediated the relationship between ethnicity and PWE values. The authors concluded that perception of social class is an important construct that might influence the cultural psychology of different ethnic groups. The authors recommended further research involving PWE and other cultural variables.     

Knowledge Based Solution Strategies in Medical Reasoning

The techniques of propositionol analysis are used to examine the protocols of seven cardiologists in a task involving the diagnosis of a case of acute bacterial endocarditis and an explanation of its underlying pathophysiology. It is shown that the explanations of physicians making an accurate diagnosis can be accounted for in terms of a model consisting of pure forward reasoning through a network of causal rules, actuated by relevant propositions embedded in the stimulus text. These rules appear to derive from the physician's underlying knowledge base rather than any information in the text itself. In contrast, subjects with inacurate diagnoses tend to make use of a mixture of forward and backward reasoning, beginning with a high level hypothesis and proceeding in a top-down fashion to the propositions embedded in stimulus text, or to the generation of irrelevant rules.     

Handling Spirituality/Religion in Professional Training: Experiences of a Sample of Muslim Psychology Students

With increasing research interest in the relationship between spirituality/religion and mental health, the present study uses semi-structured interviews on a select group of Muslim students to explore their understanding and handling of spirituality in a secular training programme. Their understanding of spirituality, its perceived role in therapy and their training experiences are subjected to qualitative analysis using the framework approach (Ritchie & Spencer, 1994. In A. Bryman & R.G. Burgess (Eds), Analysing Qualitative Data. London: Routledge). All five participants perceived spirituality as central to human functioning. Probes into their training experience uncovered issues of bias against religious applicants, apprehension about demonstrating religious commitment, fear of punishment for compromising religious integrity, better rapport with Muslim patients but general uncertainty about handling spiritual issues in therapy, and a strong desire for the integration of spirituality/religion in the program.Cynthia Joan Patel, M.A., is a Lecturer in the School of Psychology at the University of Kwazulu-Natal, Westville Campus, Durban, South Africa.

The Behavioral and Pharmacological Actions of NMDA Receptor Antagonism are Conserved in Zebrafish Larvae

Dizocilpine maleate (MK-801) is one of several NMDA receptor antagonists that is widely used to pharmacologically model the symptoms of psychosis and schizophrenia in animals. MK-801 elicits behaviors in adult zebrafish (Danio rerio) that are phenotypically consistent with behaviors observed in humans and rodents exposed to tbhe drug. However, the molecular and cellular processes that mediate the psychotomimetic, cognitive and locomotive behaviors of MK-801 are unclear. We exposed zebrafish larvae to MK-801 to assess their merit as a model organism to elucidate the behavioral effects of NMDA receptor blockade. Zebrafish larvae were acutely immersed in MK-801 to assess the effect on spontaneous swimming. MK-801 caused a time- and dose-dependent increase in larval swim speed, and the peak response (a five-fold increase in swim speed) was evoked by a three h exposure to a 20 uM dose. Zebrafish larvae did not exhibit sensitivity to the locomotor effects of MK-801 until 5 dpf, suggesting a critical role for developmental in sensitivity to the drug. Exposure to the low potency NMDA antagonist, memantine, did not alter the swim speed of zebrafish larvae. Co-immersion in D(1) or D(2) dopamine receptor antagonists did not disrupt the time course or magnitude of the increase in swim speed, suggesting dopaminergic signaling is not required for the locomotor actions of MK-801. Our findings of the behavioral actions of MK-801 in zebrafish larvae are consistent with previous observations in mammals and imply that the physiological, cellular and molecular processes disrupted by MK-801 are conserved in zebrafish larvae. These data suggest that the zebrafish larvae is a valid and useful model to elucidate neurobehavioral aspects of NMDA receptor antagonism and may provide insight to the neurobiology of psychosis and schizophrenia.     

Accuracy of Reported Community Diagnosis of Autism Spectrum Disorder

To compare community diagnoses of Autism Spectrum Disorder (ASD) reported by parents to consensus diagnoses made using standardized tools plus clinical observation. 87 participants (85% male, average age 7.4 years), with reported community diagnosis of ASD were evaluated using the Autism Diagnostic Observation Schedule) (ADOS-2), Differential Ability Scale (DAS-II), and Vineland Adaptive Behavior Scales (VABS-II). Detailed developmental and medical history was obtained from all participants. Diagnosis was based on clinical consensus of at least two expert clinicians, using test results, clinical observations, and parent report. 23% of participants with a reported community diagnosis of ASD were classified as non-spectrum based on our consensus diagnosis. ASD and non-spectrum participants did not differ on age at evaluation and age of first community diagnosis. Non-verbal IQ scores and Adaptive Behavior Composite scores were significantly higher in the non-spectrum group compared to the ASD group (104.5?±?21.7 vs. 80.1?±?21.6, p?<?.01; 71.1?±?15 versus 79.5?±?17.6, p?<?.05, respectively). Participants enrolled with community diagnosis of PDD-NOS were significantly more likely to be classified as non-spectrum on the study consensus diagnosis than Participants with Autism or Asperger (36% versus 9.5%, Odds Ratio?=?5.4, p?<?.05). This study shows suboptimal agreement between community diagnoses of ASD and consensus diagnosis using standardized instruments. These findings are based on limited data, and should be further studied, taking into consideration the influence of DSM 5 diagnostic criteria on ASD prevalence.
