Stress in Prison

Description

This data set consists of the stress levels presented by 26 individuals in an experimental study conducted by Verdot et al. (2010) in a French penitentiary. The inmates were divided into two groups, one formed by individuals who spontaneously opted to practice sports; and another one with those who did not wish to perform physical activity. The observations consist of the stress levels presented by detainees at the beginning and end of the experiment.

Usage

data(pss)

Format

A data frame with 26 observations on the following 4 variables.

• group: a factor, which identifies whether the individual belongs to the control or the experimental group.

• pss_before: stress measurement before training.

• pss_after: stress measurement before training.

• difference: the difference between the stress levels obtained at the end of the experiment and at the beginning, that is, pss_after - pss_before.

Details

To measure the stress level, Verdot et al (2010) used the Perceived Stress Scale (PSS) (Cohen, Kamarck and Mermelstein, 1983), which is a discrete scale and one of the most used psychological tools to measure the levels of perceived non-specific stress in an individual.
