Research tools for assessing nonsuicidal self-injury (NSSI) epidemiology in community populations are few and are either limited in the scope of NSSI characteristics assessed or included as part of suicide assessment. Though these surveys have been immensely useful in establishing the presence of NSSI and in documenting basic epidemiological characteristics, they have been less useful in descri...

Introduction: Since the 1950s, air travel has grown exponentially. In 2018, the number of international air passengers was estimated at 4.1 billion. Air travel exposes the passenger to a number of constraints (like physical constraints, stress) that can be correlated and lead to an inflight medical event, especially for passengers with chronic conditions or fragile health.<br /...

The objective of the present research was to develop a single measure of the major symptoms of both neuropathic and non-neuropathic pain that can be used in studies of epidemiology, natural history, pathophysiologic mechanisms, and treatment response. We expanded and revised the Short-form McGill Pain Questionnaire (SF-MPQ) pain descriptors by adding symptoms relevant to neuropathic pain and by...

The Structured Interview for Hoarding Disorder (SIHD) is a semi-structured instrument designed to assist clinicians and trained interviewers with the nuanced diagnosis of hoarding disorder (HD). The manuscript introduces the rationale, development, and design of the SIHD and presents a test of the instrument's inter-rater reliability and convergent/discriminant validity. Ninety-nine individuals...

Lindley distribution is a continuous with various applications some of which are in medicine, genetics, epidemiology, biology, finance and actuarial sciences, ecology, meteorology, sociology, demography, agriculture, hydrology, geosciences, reliability engineering, life testing survival analysis, airborne systems communications, environmental studies modeling describing human mistakes, strikes,...

In the context of COVID-19 pandemic, there is a need to adjust educational programs at medical universities for in-depth study epidemiology and infection prevention in such disciplines as “epidemiology hygiene”, which are necessary training qualified preventive doctors, who currently high demand various institutions industrial

Clinical epidemiology versus public health epidemiology Epidemiology is growing, and so is the need for developing subspecialties. One subspecialty which has achieved a certain prominence is clinical epidemiology. The term had already been coined in 1938,1 and although it has many different interpretations,2 the growing number of textbooks providing an introduction to the area shows that it has...

A plethora of software reliability models have been developed over the years but, in spite of extravagant claims for their efficacy, none can be trusted to give accurate results in all circumstances. This presents potential users with a serious difficulty, and has probably been the main reason why there has been such a poor take-up of these techniques. Recent work in CSR has largely overcome th...

This article is a continuation of the previous module on designing questionnaires and clinical record form in which we have discussed some basic points about designing the questionnaire and clinical record forms. In this section, we will discuss the reliability and validity of questionnaires. The different types of validity are face validity, content validity, criterion validity, and construct ...
