Personality disorders as a predictor of counterproductive knowledge behavior: the application of the Millon Clinical Multiaxial Inventory-IV

PurposeThis study investigates the role of personality disorders in the context of counterproductive knowledge behavior.Design/methodology/approachData were collected through a survey administered to 120 full-time employees recruited from Amazon’s Mechanical Turk. Personality disorders were measured by means of the Millon Clinical Multiaxial Inventory-IV.FindingsPersonality disorders play an important role in the context of counterproductive knowledge behavior: employees suffering from various personality disorders are likely to hide knowledge from their fellow coworkers and engage in knowledge sabotage. Of particular importance are dependent, narcissistic and sadistic personality disorders as well as schizophrenic and delusional severe clinical syndromes. There is a need for a paradigm shift in terms of how the research community should portray those who engage in counterproductive knowledge behavior, reconsidering the underlying assumption that all of them act deliberately, consciously and rationally. Unexpectedly, most personality disorders do not facilitate knowledge hoarding.Practical implicationsOrganizations should provide insurance coverage for the treatment of personality disorders, assist those seeking treatment, inform employees about the existence of personality disorders in the workplace and their impact on interemployee relationships, facilitate a stress-free work environment, remove social stigma that may be associated with personality disorders and, as a last resort, reassign workers suffering from extreme forms of personality disorders to tasks that require less interemployee interaction (instead of terminating them).Originality/valueTo the best of the authors’ knowledge, this work represents one of the first attempts to empirically investigate the notion of personality disorders in the context of knowledge management.

The Prevalence of Personality Disorders among Emergency Nurses Based on MMPI-2 Questionnaire; a Cross-sectional Study.

The prevalence of behavioral disorders is substantially higher in stressful working environments such as emergency departments. The present study aimed to evaluate the prevalence of personality disorders among emergency nurses. In the present epidemiologic study, the prevalence of personality disorders among emergency nurses of three educational hospitals, Tehran, Iran, were evaluated based on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) test. After the questionnaires were filled, data were entered to a special software for MMPI-2 test and the final result was interpreted based on the opinion of a clinical psychologist. Findings were reported using descriptive statistics. 102 emergency nurses with the mean age of 30.2 ± 5.6 years were enrolled (100% female; 100% with master's degree in nursing). The mean working time and experience of studied nurses were 210.8 ± 47.9 hours/month (130-370) and 4.1 ± 3.6 years (1-20), respectively. 32 (31.4%) cases showed symptoms of personality disorders The most common personality disorder detected in this study was somatization with 8.8%, hysteria with 6.9% prevalence, and pollyannaish with 4.9%. Among the studied factors only recent history of unpleasant event has significant correlation with existence of personality disorders (p = 0.015). The present study showed that somatization, hysteria, and pollyannaish were the most common personality disorders among the emergency nurses. History of an unpleasant event in the past year was the only effective factor in existence of personality disorders in the studied nurses.

Le psychiatre de liaison et le Tako Tsubo…

Stress cardiopathy, also called "Tako Tsubo" is a cardiac pathology linked to an acute coronary syndrome with electrocardiographic signs and an increase in the level of cardiac enzymes, without any abnormality on coronarography. This syndrome is secondary to great physical or mental stress. Mortality and the risk of recurrence are low. However, there is no consensus for treatment or prevention.We report the case of 75-year-old woman presenting recurrent cardiogenic shocks. A symptomatic sinusal dysfunction motivated the introduction of a pacemaker in March 2008. One month later, she was hospitalized for a new cardiogenic shock with left ventricular dysfunction, a 40% ejection fraction, and a third degree mitral insufficiency. Cardiac enzymes were initially elevated. Electrocardiogram showed an ST elevation. The transthoracic echocardiogram revealed a left anterolateral ventriculogram dysfunction, and cardiac catheterization showed healthy coronary arteries. The cardiologist wondered about the existence of an anxiodepressive syndrome. No personal psychiatric background was known. The patient was widowed 3 years earlier. She described herself as a naturally anxious person. She hadn't experienced any recent stressing event. She was not depressed and wasn't taking any psychotropic drug. Her family was caring for her. The next day, the patient had another cardiogenic shock and died a few hours later. Maybe the introduction of the pacemaker occasioned one more stress for this patient…We know that people with a stressing job have probably more chance to suffer a myocardial infarction (the risks are 1.5 or two times greater for them). The prevalence of cardiomyopathy syndrome is 4.9% for women. These women have gone through the menopause, with a history of hypertension and anxiodepressive symptoms. However, we do not find any similar description (behavioural scheme type A) as is shown by the psychosomatic school in cases of patients who have gone through myocardial infarction. We also can question ourselves about the fact that some people can be predisposed to suffer from "Tako Tsubo" cardiomyopathy and about the existence of personality disorders. What then is the role of the psychiatrist with these patients?
