Background

Individuals who utilize Brain.fm have the opportunity to utilize their app and respond

to their Stress Survey which consists of five stress characteristics: Anxiety, Focus,

Mood, Sleep and Stress. Each characteristics is measured with three dichotomousitems where Yes is indicated by 1 and No is indicated by 0. Participants might take the

survey several times, but the present study took only the first response and the last

response.

Analysis

There are five areas of stress (sleep, focus, anxiety, stress, and mood). Each area is

measured by three binary items (yes = 1, stress, or no = 0 stress). The average area of

stress was computed. For example, on the pretest, 58% of the 274 respondentsindicate sleep stress. On the posttest 49% indicated sleep stress. This shows a

decrease of sleep stress from pretest to posttest.

On all five of the stress areas, there was a decrease of stress from pretest to posttest.

See Table 1.

2. Focus 274 .73 .31 .58 .41 .15

5. Mood 274 .49 .30 .39 .34 .10

The correlations between all of the stress areas were computed. All correlations were

statistically significant. For example the correlation between sleep and mood was .35.

In research periodicals this would be indicated as r = .35, p < .01. In words, this would

be stated that there is a tendency for those high with sleep stress to also be high on

mood stress. In addition those who were low on sleep stress also tended to be low onmood stress.

These correlations indicate some stress relationship underlying all of these five

measures of stress. See Table 2.
