A cross-cultural analysis of the Brief Symptom Inventory-18

The Brief Symptom Inventory-18 (BSI-18: Derogatis, 2000) is an abbreviated version of the nine dimension, 53-item BSI (Derogatis, 1993) which is a shortened form of the 90-item Symptom Checklist-90-Revised (SCL-90-R: Derogatis, 1994). Criticism focused on factor structure (cf. Boulet & Boss, 1991; Ruipérez, Ibá?ez, Lorente, Moro, & Ortet, 2001) and the two older versions' poor discriminant validity suggest the scales' usefulness is limited to global scores only. Using principal component analysis, the authors explore the three-dimension factor structure of the BSI - 18 with the understudied population of Central American immigrants to the U.S. (N = 100). Results suggest one underlying factor best used in aggregate as a general screening for overall levels of psychological distress. Cultural differences are discussed.     

Adrenocorticotrophic hormone modulates Escherichia coli O157:H7 adherence to porcine colonic mucosa

Exposure to stress is associated with susceptibility to disease and one stress mediator, norepinephrine, has been reported to enhance the adherence of enterohemorrhagic Escherichia coli O157:H7 (EHEC) to the colonic mucosa. We tested the hypothesis that adrenocorticotropic hormone (ACTH) and other stress-related hormones may act in a similar fashion. Explants of distal colonic mucosa from young pigs were mounted in Ussing chambers and their luminal aspect was exposed to EHEC strain 700728 for 30-90 min. When added to the contraluminal, but not luminal bathing medium, ACTH increased EHEC adherence within 90 min in a concentration-dependent manner (EC50 = 1.2 nM), but did not alter tissue electrical conductance. ACTH had no effect on the adherence of a pig-adapted non-O157 E. coli strain. The effect of 0.1 microM ACTH on luminal EHEC adherence was prevented in tissues pretreated contraluminally with the type 2 melanocortin receptor antagonist ACTH7-38, the neuronal conduction blocker saxitoxin, or the muscarinic cholinergic antagonist atropine. Moreover, ACTH7-38 decreased EHEC adherence in the absence of ACTH. These results suggest that ACTH acts via melanocortin receptors located on enteric nerves to enhance mucosal adherence of EHEC.     

Multisensory processing in the redundant-target effect: a behavioral and event-related potential study

Participants respond more quickly to two simultaneously presented target stimuli of two different modalities (redundant targets) than would be predicted from their reaction times to the unimodal targets. To examine the neural correlates of this redundant-target effect, event-related potentials (ERPs) were recorded to auditory, visual, and bimodal standard and target stimuli presented at two locations (left and right of central fixation). Bimodal stimuli were combinations of two standards, two targets, or a standard and a target, presented either from the same or from different locations. Responses generally were faster for bimodal stimuli than for unimodal stimuli and were faster for spatially congruent than for spatially incongruent bimodal events. ERPs to spatially congruent and spatially incongruent bimodal stimuli started to differ over the parietal cortex as early as 160 msec after stimulus onset. The present study suggests that hearing and seeing interact at sensory-processing stages by matching spatial information across modalities.     

Determinants of the remembered utility of aversive sounds

Retrospective evaluations of aversive episodes were studied in the context of a general model of "judgment by prototype" that has been applied in other situations. Unpleasant sounds of variable loudness and duration were the stimuli. In Experiment 1, continuous reports of annoyance closely tracked variations of noise intensity. Hypotheses about the determinants of retrospective evaluation were examined in Experiment 2. Experiment 3 confirmed a prediction of judgment by prototype: The effects of sound duration and intensity are additive in multitrial experiments. Experiment 4 confirmed a robust preference for aversive episodes that are "improved" by adding a period of reduced aversiveness.     

Offense Characteristics of Incompetent to Stand Trial Defendants Charged With Violent Offenses

The current study compared offender and offense characteristics of pretrial defendants found incompetent to stand trial (IST) against those described as general offenders by victims in the 2008 Bureau of Justice Statistics (BJS) survey and evaluated factors that differentiated IST defendants who allegedly used weapons from those who did not during the course of a violent offense. IST defendants were older and used “weapons” more frequently than those reported in the BJS survey; however, other characteristics, including use of firearms, did not differ. No demographic, clinical, or legal factors differentiated pretrial defendants who used weapons from those who did not. Overall, pretrial defendants were frequently diagnosed with a comorbid substance use disorder, and were homeless, unemployed, and had an extensive history of psychiatric hospitalizations and prior arrests at the time of their alleged offenses. Such results indicate that models for comprehensive discharge planning may have utility in addressing the unique needs of this subgroup of mentally disordered offenders. The findings also raise questions about the federal and state prohibition of gun rights to all IST defendants. Copyright © 2015 John Wiley & Sons, Ltd.     

“Blind” interviewing: Is ignorance bliss?

Current investigative interviewing guidelines [e.g., Technical Working Group: Eyewitness evidence. (1999). Eyewitness evidence: A guide for law enforcement. U.S. Department of Justice, Office of Justice Programs, National Institute of Justice. Retrieved from https://www.ncjrs.gov/pdffiles1/nij/178240.pdf] suggest that interviewers review available case information prior to conducting a witness interview. The present study investigated the effect of interviewers’ pre-interview awareness of crime details on eyewitnesses’ memory and interviewer behaviour shortly after a mock crime or a week later. Results indicate that blind interviewers with no knowledge about the crime elicited more correct information than those who were correctly informed about the crime. Differences in interviewer behaviour emerged only in the very first question of the interview: Blind interviewers were more likely to begin the interview with a non-suggestive question than the informed interviewers. Blind interviewers also recalled more details than the informed interviewers when asked to generate a report after the witness interview documenting the witness’ account.     

Religious conversion among high security hospital patients: a qualitative analysis of patients’ accounts and experiences on changing faith

Research has shown the importance of religion in recovery from mental illness. Previous studies have investigated why individuals change faith during custody in prison, but there has been no research to date on religious conversion in forensic-psychiatric hospitals. The aim of this study was to understand the experience of religious conversion among patients detained in a UK secure hospital. Thirteen patients who had converted their religion were interviewed and the resultant data were analysed using thematic analysis. Three superordinate themes (“reasons for changing faith”, “benefits of having a new faith” and “difficulties with practising a faith”), incorporating eight subordinate themes, emerged. Understanding patients’ reasons for religious conversion is important for the treatment and support not merely of these individuals, but more broadly with patients in forensic-psychiatric care.     

Anxiety,depression, and health-related quality of life in aging people living with HIV compared to diabetes patients and patients with minor health conditions: a longitudinal study

HIV infection has evolved from a fatal to a treatable condition, leading to an increase in the rate of elderly People Living with HIV (PLWH). However, little is known about the psychosocial burden of elderly PLWH. Thus, the aim of this longitudinal multi-center cohort study was to investigate whether elderly PLWH experience more anxiety and depression and reduced health related quality of life (HRQOL) compared to elderly patients with other chronic conditions. PLWH were compared to diabetes patients (DM) and patients with minor health conditions (MHC), e.g. patients with hypertension or allergic conditions. All patients were over 50 years old. Anxiety and depression (HADS) as well as HRQOL (SF-36) were assessed at baseline and after 12 months. 218 PLWH, 249 DM and 254 MHC were included. At baseline, the study groups did not differ in anxiety, depression, and physical HRQOL. However, PLWH indicated lower mental HRQOL than DM and MHC patients (p = 0.001). We did not obtain any moderating effects showing a differential effect of patient characteristics on anxiety, depression, and HRQOL in the three patient groups. At follow-up, the level of anxiety, depression, and HRQOL did not change significantly. The prevalence of anxiety ranged between 27 and 35%, and that of depression between 17 and 28%. Thus, the results of our investigation tentatively suggest that the psychosocial adaptation to HIV among elderly PLWH resembles those of other chronic diseases. There may be some subtle impairments, though, as PLWH experienced lower mental HRQOL.     

The University of South Florida free association, rhyme, and word fragment norms.

Preexisting word knowledge is accessed in many cognitive tasks, and this article offers a means for indexing this knowledge so that it can be manipulated or controlled. We offer free association data for 72,000 word pairs, along with over a million entries of related data, such as forward and backward strength, number of competing associates, and printed frequency. A separate file contains the 5,019 normed words, their statistics, and thousands of independently normed rhyme, stem, and fragment cues. Other files provide n x n associative networks for more than 4,000 words and a list of idiosyncratic responses for each normed word. The database will be useful for investigators interested in cuing, priming, recognition, network theory, linguistics, and implicit testing applications. They also will be useful for evaluating the predictive value of free association probabilities as compared with other measures, such as similarity ratings and co-occurrence norms. Of several procedures for measuring preexisting strength between two words, the best remains to be determined. The norms may be downloaded from www.psychonomic.org/archive/.
