Question

Here is a brief summary of the data collection plan of a fictitious study. Read the summary and then respond to the questions that follow.
Traina conducted a study to investigate the relationship between adults' blood pressure and their suppression of anger. Data were gathered from a sample of 347 healthy men and women aged 22 to 60 who were members of a gym in Washington DC. Subjects completed two paper and pencil scales: The Feeling of Anger Scale and the Expression of Anger Scale. The scales used a 9 point rating scales. Responses to each scale were summed to yield a total score for each variable. The subjects' BP was measured by nurses using zero calibrated aneroid sphygmomanometers. Weight was measured with subjects wearing only gym shorts and a t-shirt on an upright scale to the nearest 10th of a pound. Heights was measured without shoes, feet together. All instruments were assessed at being below the eighth grade level. The results indicated for both men and women higher diastolic and systolic BP was associated with higher levels of suppressed anger even when various variables were statistically controlled.
a. Which of the following types of data were collected in this study (self-report, observation, biophysiologic, records)?
b. Were the data collection methods structured or unstructured?
c. For which variables did Traina NOT derive numeric information?
d. Which of the following specific methods were used (likert-type scale, semantic differential scale, event history calendar, rank-order questions, Q-sort)?
e. Which type of data collection was used: telephone interview, personal interview, web-based interview, or self-administered questionnaire?
f. Was readability assessed? At what level?
g. Provide at least one way that data collection and measurement effort be improved in this study based on your readings. Here is a brief summary of the data collection plan of a fictitious study. Read the summary and then respond to the questions that follow.

Explanation / Answer

A, self-report, observation and biophysical data were collected in this study.

B, it is structured because subjects the feeling of anger scale and the expression of anger scale.

C,the scale used a 9 point rating scales..Responses for each were summed to yield a total score for each variable..Triana not derive numeric information for BP measuring.

D, Rank- order question they used.This survey compare differ items using a common scale..

E, .Data collection was used is personal interview..

F, yes here readability assessed at being below the eight grade level.

G, there are many factors that impact the quality of a research study.The research proposal should be based on scientific principles.In all sources of bias should be eliminated or reduce bias where possible..
