SAPROF was developed in the Netherlands in 2007 as an instrument for the structured assessment of protective factors for violence risk. Following the structured professional judgment model, the SAPROF was designed as a positive addition to other SPJ risk assessment tools, such as the HCR-20, [1] which at the time was considered the most widely used tool for structured professional judgement.
A retrospective cohort study, also called a historic cohort study, is a longitudinal cohort study used in medical and psychological research. A cohort of individuals that share a common exposure factor is compared with another group of equivalent individuals not exposed to that factor, to determine the factor's influence on the incidence of a ...
The SPF consists of twenty-four statements for which individuals are asked to rate the degree to which each statement describes them. The SPF assesses a wider range of protective factors than other scales. The SPF is the only measure that has been shown to assess social and cognitive protective factors. [2]
Conversely, a Risk factor will increase the chances of a negative health outcome occurring. Just as statistical correlations and regressions can examine how a range of independent variables impact a dependent variable, we can examine how many Protective and Risk factors contribute to the likelihood of an illness occurring.
As the surveillance and reporting of diseases and other health factors become increasingly difficult in humanitarian crisis situations, the methodologies used to report the data are compromised. One study found that less than half (42.4%) of nutrition surveys sampled from humanitarian contexts correctly calculated the prevalence of malnutrition ...
The respiratory protective devices (RPD) can protect workers only if their protective properties are adequate to the conditions in the workplace.Therefore, specialists have developed criteria for the selection of proper, adequate respirators, including the Assigned Protection Factors (APF) - the decrease of the concentration of harmful substances in the inhaled air, which (is expected) to be ...
Using this score function and Hessian matrix, the partial likelihood can be maximized using the Newton-Raphson algorithm. The inverse of the Hessian matrix, evaluated at the estimate of β , can be used as an approximate variance-covariance matrix for the estimate, and used to produce approximate standard errors for the regression coefficients.
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and an abbreviated variant of it, the SF-6D, is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment.
