Factor structure of the Japanese Interpersonal Competence Scale

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2008
Tomomi Matsudaira ma
Aim:, Assessing social competence is important for clinical and preventive interventions of depression. The aim of the present paper was to examine the factor structure of the Japanese Interpersonal Competence Scale (JICS). Methods:, Exploratory and confirmatory factor analysis was performed on the survey responses of 730 participants. Simultaneous multigroup analyses were conducted to confirm factor stability across psychological health status and sex differences. Results:, Two factors, which represent Perceptive Ability and Self-Restraint, were confirmed to show a moderate correlation. Perceptive Ability involves a more cognitive aspect of social competence, while Self-Restraint involves a more behavioral aspect, both of which are considered to reflect the emotion-based relating style specific to the Japanese people: indulgent dependence (amae) and harmony (wa). In addition, Self-Restraint may be linked to social functioning. Both constructs may confound a respondent's perceived confidence. Conclusion:, Despite its shortcomings, the JICS is a unique measure of social competence in the Japanese cultural context. [source]

Stimulation of the subthalamic nucleus and impulsivity: Release your horses,

ANNALS OF NEUROLOGY, Issue 6 2009
Benedicte Ballanger PhD
Objective In Parkinson disease (PD) patients, deep brain stimulation (DBS) of the subthalamic nucleus (STN) may contribute to certain impulsive behavior during high-conflict decisions. A neurocomputational model of the basal ganglia has recently been proposed that suggests this behavioral aspect may be related to the role played by the STN in relaying a "hold your horses" signal intended to allow more time to settle on the best option. The aim of the present study was 2-fold: 1) to extend these observations by providing evidence that the STN may influence and prevent the execution of any response even during low-conflict decisions; and 2) to identify the neural correlates of this effect. Methods We measured regional cerebral blood flow during a Go/NoGo and a control (Go) task to study the motor improvement and response inhibition deficits associated with STN-DBS in patients with PD. Results Although it improved Unified Parkinson Disease Rating Scale motor ratings and induced a global decrease in reaction time during task performance, STN-DBS impaired response inhibition, as revealed by an increase in commission errors in NoGo trials. These behavioral effects were accompanied by changes in synaptic activity consisting of a reduced activation in the cortical networks responsible for reactive and proactive response inhibition. Interpretation The present results suggest that although it improves motor functions in PD patients, modulation of STN hyperactivity with DBS may tend at the same time to favor the appearance of impulsive behavior by acting on the gating mechanism involved in response initiation.

Can experimental paradigms and animal models be used to discover clinically effective medications for alcoholism?

ADDICTION BIOLOGY, Issue 4 2005
Mark Egli
Evaluating medications in animal laboratory paradigms can reveal whether the compound is effective in an established alcoholism model, at clinically relevant doses and exposure conditions, when administered orally (or transdermally) and without serious limiting side effects. Positive outcomes constitute a possible discovery for relevance to alcoholism and, under favorable marketing conditions, encourage further development. Medication testing using animal models of alcoholism might also guide clinical testing by discriminating clinically effective from clinically ineffective compounds. This ability rests on whether there are tests or, more reasonably, batteries of tests having this discriminative ability. The present paper examines this possibility. Effects of naltrexone and acamprosate in animal paradigms which model behavioral aspects of alcoholism are reviewed and compared with the effects of compounds which have limited effects in alcoholics. It is not clear at present whether any single paradigm or combination of paradigms differentiates clinically effective from clinically limited compounds. Steps are suggested to improve the use of preclinical laboratory tests to predict which compounds are likely to be effective medications for reducing drinking and sustaining abstinence in human alcoholics.

Longitudinal Changes in Religiosity Among Emerging Adult College Students

JOURNAL OF RESEARCH ON ADOLESCENCE, Issue 1 2010
Tara M. Stoppa
Issues of religion are important aspects of the identity process, which for many emerging adults may be intensified by the college experience. This study investigated longitudinal changes in the religiosity of 434 emerging adult college students (52% female) of diverse ethnic backgrounds (32% African American, 29% Latino American, and 39% European American) during the first 3 semesters of university. Results suggest that changes occur throughout this period, but that such changes are not monolithic across dimensions of religiosity. In the aggregate, significant declines in the behavioral aspects of religiosity were observed across semesters. In contrast, importance of religious beliefs remained relatively constant during this time. However, variations in these patterns were observed when considered at the individual level. Findings further demonstrate that heterogeneity in religiosity is also evident based upon gender and religious affiliation, suggesting that it is fruitful to consider the unique ways in which individuals change during this developmental period.

Pain management in horses and farm animals

JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 4 2005
Alexander Valverde DVM, DACVA
Abstract Objective: This review discusses the different analgesic drugs and routes of administration used in large animals for acute pain management. General guidelines and doses are given to assist in choosing techniques that provide effective analgesia. Etiology: Noxious stimuli are perceived, recognized, and localized by specialized sensory systems located at spinal and supraspinal levels. Diagnosis: Localizing the source of the noxious stimulus as well as understanding the behavioral aspects and physiological changes that result from such insult is important to adequately diagnose and treat pain. Pain assessment is far from being definite and objective; not only are there species differences, but also individual variation. In addition, the behavioral and physiological manifestations vary with the acute or chronic nature of pain. Therapy: Pain management should include (1) selecting drugs that better control the type of pain elicited by the insult; (2) selecting techniques of analgesic drug administration that act on pathways or anatomical locations where the nociceptive information is being processed or originating from; (3) combining analgesic drugs that act on different pain pathways; and (4) provide the best possible comfort for the animal. Prognosis: Providing pain relief improves the animal's well being and outcome; however, interpreting and diagnosing pain remains difficult. Continuing research in pain management will contribute to the evaluation of the pathophysiology of pain, pain assessment, and newer analgesic drugs and techniques. [source]
