Structured Inventory Of Malingered Symptomatology
The Structured Inventory of Malingered Symptomatology (SIMS) is a 75-item true-false questionnaire intended to measure malingering; that is, intentionally exaggerating or feigning psychiatric symptoms, cognitive impairment, or neurological disorders. Psychometric Characteristics Low Specificity If psychologists rely on the SIMS Manual's recommended cut score of 14, the SIMS has substandard specificity. For instance, SIMS specificity calculated by Richard Rogers et al. for a total SIMS cutoff score of over 14 was 0.28: With this inpatient sample, the recommended SIMS total cut score of >14 functioned poorly, because most genuine responders also exceeded this cut score (i.e., specificity = .28). Even at a 25% base rate, more than two thirds (positive predictive power, PPP = .70) of those identified will be genuine responders. At least for these inpatients, a much higher SIMS total cut score (> 44) is required to achieve a very high specificity. Low specificity hinders the tes ...

Malingering
Malingering is the fabrication, feigning, or exaggeration of physical or psychological symptoms designed to achieve a desired outcome, such as relief from duty or work. Malingering is not a medical diagnosis, but may be recorded as a "focus of clinical attention" or a "reason for contact with health services". Malingering is categorized as distinct from other forms of excessive illness behavior such as somatization disorder and factitious disorder, although not all mental health professionals agree with this formulation. Failure to detect actual cases of malingering imposes an economic burden on health care systems, workers' compensation programs, and disability programs, such as Social Security Disability Insurance and veterans' disability benefits. False accusations of malingering often harm genuine patients or claimants. History Antiquity According to 1 Samuel in the Old Testament, King David feigned madness to Achish, the king of the Philistines. Some scholars believe t ...

Sensitivity And Specificity
''Sensitivity'' and ''specificity'' mathematically describe the accuracy of a test which reports the presence or absence of a condition. Individuals for which the condition is satisfied are considered "positive" and those for which it is not are considered "negative". *Sensitivity (true positive rate) refers to the probability of a positive test, conditioned on truly being positive. *Specificity (true negative rate) refers to the probability of a negative test, conditioned on truly being negative. If the true condition can not be known, a " gold standard test" is assumed to be correct. In a diagnostic test, sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can identify true negatives. For all testing, both diagnostic and screening, there is usually a trade-off between sensitivity and specificity, such that higher sensitivities will mean lower specificities and vice versa. If the goal is to return the ratio at w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iatrogenesis
Iatrogenesis is the causation of a disease, a harmful complication, or other ill effect by any medical activity, including diagnosis, intervention, error, or negligence. "Iatrogenic", ''Merriam-Webster.com'', Merriam-Webster, Inc., accessed 27 Jun 2020.

Court-martial
A court-martial or court martial (plural ''courts-martial'' or ''courts martial'', as "martial" is a postpositive adjective) is a military court or a trial conducted in such a court. A court-martial is empowered to determine the guilt of members of the armed forces subject to military law, and, if the defendant is found guilty, to decide upon punishment. In addition, courts-martial may be used to try prisoners of war for war crimes. The Geneva Conventions require that POWs who are on trial for war crimes be subject to the same procedures as would be the holding military's own forces. Finally, courts-martial can be convened for other purposes, such as dealing with violations of martial law, and can involve civilian defendants. Most navies have a standard court-martial which convenes whenever a ship is lost; this does not presume that the captain is suspected of wrongdoing, but merely that the circumstances surrounding the loss of the ship be made part of the official record.

Uniform Code Of Military Justice
The Uniform Code of Military Justice (UCMJ, 10 U.S.C. §§ 801–946 is the foundation of military law in the United States. It was established by the United States Congress in accordance with the authority given by the United States Constitution in Article I, Section 8, which provides that "The Congress shall have Power....To make Rules for the Government and Regulation of the land and naval forces". History On June 30, 1775, the Second Continental Congress established 69 Articles of War to govern the conduct of the Continental Army. Effective upon its ratification in 1788, Article I, Section 8 of the United States Constitution provided that Congress has the power to regulate the land and naval forces. On 10 April 1806, the United States Congress enacted 101 Articles of War, which were not significantly revised until over a century later. Discipline in the sea services was provided under the Articles for the Government of the United States Navy (commonly referred to as ''Ro ...

Epidemiology Of Motor Vehicle Collisions
Worldwide it was estimated that 1.25 million people were killed and many millions more were injured in motor vehicle collisions in 2013. This makes motor vehicle collisions the leading cause of death among young adults of 15–29 years of age (360,000 die a year) and the ninth cause of death for all ages worldwide. In the United States, 40,100 people died and 2.8 million were injured in crashes in 2017, and around 2,000 children under 16 years old die every year. History and trends Road toll figures in developed nations show that car collision fatalities have declined since 1980. Japan is an extreme example, with road deaths decreasing to 5,115 in 2008, which is 25% of the 1970 rate per capita and 17% of the 1970 rate per vehicle distance travelled. In 2008, for the first time, more pedestrians than vehicle occupants were killed in Japan by cars. Besides improving general road conditions like lighting and separated walkways, Japan has been installing intelligent transportat ...

Rivermead Post-concussion Symptoms Questionnaire
The Rivermead Post-Concussion Symptoms Questionnaire, abbreviated RPQ, is a questionnaire that can be administered to someone who sustains a concussion or other form of traumatic brain injury to measure the severity of symptoms. The RPQ is used to determine the presence and severity of post-concussion syndrome (PCS), a set of somatic, cognitive, and emotional symptoms following traumatic brain injury that may persist anywhere from a week,Legome E. 2006Postconcussive syndrome.eMedicine.com. Retrieved 14 November 2012. to months, or even more than six months. The RPQ has been cited in over 40 papers. The test was presented in 1995 by a group led by N.S. King. At the time of its design, no measure of PCS severity had been developed. Questionnaire contents The test, which can be self-administered or given by an interviewer, asks patients to rate the severity of 16 different symptoms commonly found after a mild traumatic brain injury (MTBI). Patients are asked to rate how s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-concussion Syndrome
Post-concussion syndrome (PCS) is a set of symptoms that may continue for weeks, months, or a year or more after a concussion – medically classified as a so-called mild traumatic brain injury (TBI). About 34 to 35% of people with concussion experience persistent or prolonged symptoms 3 to 6 months after injury. Prolonged concussion is defined as having concussion symptoms for over four weeks following the first accident in youth and for weeks or months in adults. A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury. Loss of consciousness is not required for a diagnosis of concussion or post-concussion syndrome. However, it is important that patients find help as soon as they notice lingering symptoms within one month, and especially when they notice their mental health deteriorating, since they are at risk of post-concussion syndrome depression. Though there is no specific treatment for PCS, symptoms can be imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiplash (medicine)
Whiplash is a non-medical term describing a range of injuries to the neck caused by or related to a sudden distortion of the neck associated with extension, although the exact injury mechanisms remain unknown. The term "whiplash" is a colloquialism. "Cervical acceleration–deceleration" (CAD) describes the mechanism of the injury, while the term "whiplash associated disorders" (WAD) describes the subsequent injuries and symptoms. Whiplash is commonly associated with motor vehicle accidents, usually when the vehicle has been hit in the rear; however, the injury can be sustained in many other ways, including headbanging, bungee jumping and falls. It is one of the most frequently claimed injuries on vehicle insurance policies in certain countries; for example, in the United Kingdom 430,000 people made an insurance claim for whiplash in 2007, accounting for 14% of every driver's premium. In the United States, it is estimated that more than 65% of all bodily injury claims are whipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Industrial Disasters
This article lists notable industrial disasters, which are disasters caused by industrial companies, either by accident, negligence or incompetence. They are a form of industrial accident where great damage, injury or loss of life are caused. Other disasters can also be considered industrial disasters, if their causes are rooted in the products or processes of industry. For example, the Great Chicago Fire of 1871 was made more severe due to the heavy concentration of lumber industry facilities, wood houses, and fuel and other chemicals in a small area. The Convention on the Transboundary Effects of Industrial Accidents is designed to protect people and the environment from industrial accidents. The Convention aims to prevent accidents from occurring, to reduce their frequency and severity, and to mitigate their effects. The Convention addresses primarily industrial accidents in one country that affect the population and the environment of another country. Defense industry * Dec ...

Analysis Of Variance
Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher. ANOVA is based on the law of total variance, where the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical test of whether two or more population means are equal, and therefore generalizes the ''t''-test beyond two means. In other words, the ANOVA is used to test the difference between two or more means. History While the analysis of variance reached fruition in the 20th century, antecedents extend centuries into the past according to Stigler. These include hypothesis testing, the partitioning of sums of squares, experimental techniques and the additive model. Laplace was performing hypothesis testing ...
