Study Description: • Participants were assigned to a control group or a training group. The training group received 1 hour of training every day for one week. During the training, participants learned various techniques for decreasing their stress levels. All participants were given a life stress test to determine their current level of life stress. Scores on the test were labeled as either high or low. After a week, all participants were given a puzzle to put together in a stressful environment (e.g., loud noises, bright lights, etc.). The amount of the puzzle completed in the time frame of 5 minutes was measured according to the number of pieces completed (there were 10 pieces to the puzzle). It was expected that the training group would have different scores on the test than the control group. In addition, those who had high life stress scores were expected to perform differently than those who had low life stress scores. Lastly, those who received training and had high stress scores were expected to perform differently than those who did not receive training and had low stress scores.

The literature suggests that people can learn to better manage their everyday stress by learning and practicing stress-management regimens and stress-reduction processes. The current study investigated the influence of stress reduction training on the puzzle-solving abilities of people living with different levels of life stress. Study participants were grouped into a control group (n=15) and a treatment group (n=15), will all participants receiving training in techniques that can be used to reduce stress levels. Baseline data was collected through the

Following a period of a week, all 30 participants were required to solve a 10-piece puzzle in a stressful environment within a 5-minute period. With only 30 participants total, the sample size was small in this study.
The independent variables included the various life stress levels experienced and perceived by the research participants and the hour-long training in stress reduction they received. The quantitative data consisted of the time participants took to complete the puzzle and the number of pieces of the puzzle assembled.

The research question and the hypotheses are as follows.

RQ1: What influence does stress reduction training have on the performance of people living with different levels of life stress?

H0: stress reduction training does not have an influence on the performance of study participants engaged in a simple puzzle-solving task under stressful conditions

H1: stress reduction training does influence the performance of study participants engaged in a simple puzzle-solving task under stressful conditions

The data were analyzed through the use of SPSS, which included the provision of descriptive and inferential statistics. Descriptive statistics provide measures of central tendency and variability, which provide information about the shape of the distribution for the interval and ratio variables. The skewness and kurtosis of a distribution can provide a graphic representation of data in a frequency…
