Question

A health psychologist was interested in investigating whether mindfulness training would help people suffering from chronic pain such as arthritis. He recruited 60 middle aged residents from Albuquerque who claimed in a screening telephone interview to have suffered from chronic pain for at least two years. When subjects arrived at his lab he gave them a standard pain assessment scale to determine the extent and severity of their pain. He then randomly assigned each subject to one three groups. One group received a one-day mindfulness training workshop and a second group received a one-day training workshop in yoga. Both groups were instructed to practice their methods once a day. A third group was told that they were on a wait list and would receive pain management training when it became available. At the end of 12 weeks he administered the same pain assessment scale to all subjects. The primary dependent variable was the change in scores from the first to second assessments. He performed a one-way ANOVA on these change scores and found that both mindfulness training and the wait list groups had experienced reduced pain in comparison to the yoga group. What type of research design was used? How many levels of the independent variable were there? What were the null and research hypotheses? Can you think of an alternative way to analyze the data? Can you think of some ways to improve the study?

Explanation / Answer

the design was atched subject type as the group of 60 people were divided into 3 groups getting dfferent ,manioulations of independent variable

the independent variable is the mindfulness of training onw group got mindfulness theory the other got yoga and the third got none. hence the level of independent variabla was 3 one group got mindfulness training the other got an alternative the third got none

the data could be analysed by using the comparison method and showing a correolation between the techniques by comparing initial pain nd pain after the study

the study could have been improved by taking a larger sample size and also by increasing the variety in age group of the sample.

the hypothesis of the test is that mindfulness training helps people suffering from chronic pain and the null hypothesis is that mindfulness training doesnt has any effect on people with chronic pain
