Research Methods in Kinesiology

1


Slide2 l.jpg

Descriptive Research

  • Descriptive research is also known as non-experimental research

  • Asks the basic question: What is?

  • No manipulation of variables

  • Measure and record events that would happen anyway

2


Descriptive research cont d l.jpg
Descriptive Research, cont’d

  • Manipulation of variables may be impossible or unethical

    • Effects of megadoses of anabolic steroids on strength

    • Deliberately causing injury to study different types of therapy

  • No randomization, therefore less control and many threats to internal validity

  • Cause-and-effect is more difficult to establish

3


Slide4 l.jpg

Survey

  • Survey – technique of descriptive research that seeks to determine present practices or opinions of a specified population

  • Types of survey research include the questionnaire, interview, and normative survey

4


Examples of survey research l.jpg
Examples of Survey Research

  • Durell, D. L., Pujol, T. J., & Barnes, J. T. (2003). A survey of the scientific data and training methods utilized by collegiate strength and conditioning coaches. J Strength Cond Res, 17(2), 368-373.

  • Schick MG, Brown LE, Coburn JW, Beam WC, Schick EE, Dabbs NC. Physiological profile of mixed martial artists. Medicina Sportiva. 14(4):182-187, 2010.

  • Rossi MD, Brown LE, Whitehurst M. Knee extensor and flexor torque characteristics before and after unilateral total knee arthroplasty. American Journal of Physical Medicine & Rehabilitation. 85(9):737-746, 2006.

Questionnaire

  • Questionnaire – type of paper-and-pencil survey used in descriptive research in which information is obtained by asking participants to respond to questions rather than by observing their behavior

  • Limitation is that results are simply what people say they do, believe, like, dislike, etc.

6


Slide7 l.jpg

Questionnaire, cont’d

  • Determine the objectives

    • What information is wanted?

    • How will the results be analyzed?

    • Will comparisons be made between groups of respondents?

7


Slide8 l.jpg

Questionnaire, cont’d

  • Delimit the sample

  • What is the specific population you wish to examine?

    • Adults vs. children

    • Exercisers vs. nonexercisers (how do you define exercisers?)

    • Elite coaches

8


Slide9 l.jpg

Questionnaire, cont’d

  • Your sample must be representative of the population

    • Sampling error

      • Many samples may be drawn from a population

      • Each sample will yield different results

      • The difference between samples is the sampling error (amount of error to expect in a single sample)

    • Sample size

      • Must be adequate to represent population of interest

      • Must be practical from the standpoint of time and cost

9


Slide10 l.jpg

Questionnaire, cont’d

  • Construct the questionnaire

    • Open-ended questions

      • Category of question in questionnaires and interviews that allows the respondent considerable latitude to express feelings and to expand on ideas

      • Example: “How do you think things went today?”

      • Drawbacks:

        • Respondents don’t like them

        • They are time-consuming to answer

        • Limited control over the types of answers given

        • May be more difficult to analyze

10


Slide11 l.jpg

Questionnaire, cont’d

  • Closed questions

    • Category of question found in questionnaires or interviews that requires a specific response and that often takes the form of rankings, scaled items, or categorical responses

    • Ranking – type of closed question that forces the respondent to place responses in a rank order according to some criterion

11


Slide12 l.jpg

Questionnaire, cont’d

  • Example of Ranking: From what sources has most of your nutrition information come? Rank top 3

12


Slide13 l.jpg

Survey Research Process, cont’d

  • Scaled items – type of closed question that requires participants to indicate the strength of their agreement or disagreement with some statement or the relative frequency of some behavior

  • Example of scaled item: In a required physical education program, students should be required to take at least one dance class.

    • Strongly disagree

    • Disagree

    • Undecided

    • Agree

    • Strongly agree

13


Slide14 l.jpg

Questionnaire, cont’d

  • Likert-type scale – consists of 3 to 9 items

  • Equal intervals between responses, i.e., difference between “strongly agree, and “agree is considered equivalent

14


Slide15 l.jpg

Questionnaire, cont’d

  • Categorical response – type of closed question that offers the participant only two responses, such as yes or no

  • Possible responses include yes/no, true/false, female/male, etc.

15


Slide16 l.jpg

Questionnaire, cont’

  • Appearance and design

    • Appearance has been shown to affect response rate

    • Provide written instructions for completion

    • First few questions should be easy to answer

    • Short questionnaires have higher response rates

16


Slide17 l.jpg

Questionnaire, cont’d

  • Conduct a pilot study

    • Send questionnaire to colleagues or acquaintances

    • Revise and send to sample of population of interest

    • Analyze results as part of pilot study

    • Revise again and use

17


Slide18 l.jpg

Questionnaire, cont’d

  • Write the cover letter

    • Be professional and concise

    • Explain purpose and importance

    • Assure respondent of their privacy and anonymity

    • Use institutional letterhead if applicable

    • Rewards and incentives may be used, including money

18


Slide19 l.jpg

Questionnaire, cont’d

  • Send the questionnaire

    • Include self-addressed, stamped envelope

    • E-mail, fax, and the internet may also be used

19


Slide20 l.jpg

Questionnaire, cont’d

  • Follow-up

    • Wait at least 10 days for follow-up

    • Wait another 10 days then send another questionnaire

    • Keep in mind that respondents are “self-selected” and this biases your results

20


Slide21 l.jpg

Questionnaire, cont’d

  • Analyze the results

    • These topics will be discussed later in class

21


Slide22 l.jpg

Delphi Survey Method

  • Delphi survey method – survey technique that uses a series of questionnaires in such a way that the respondents (usually experts) reach a consensus about the subject

    • Survey is sent to respondents (experts)

    • Results are sent to respondents and they are asked to reconsider their answers

22


Slide23 l.jpg

Essentially the same as the questionnaire except questioning is done orally instead of in writing

Higher response rate but smaller samples than questionnaire

Personal Interview

23


Slide24 l.jpg

Personal Interview, cont’d is done orally instead of in writing

  • Advantages of the personal interview:

    • More adaptable

    • Interviewer can observe the respondent

    • Greater rate of return than questionnaire

    • Easier to explain questions

24


Normative survey l.jpg
Normative Survey is done orally instead of in writing

  • Normative survey – survey method that involves establishing norms for abilities, performances, beliefs, and attitudes

  • Similar to questionnaire except that tests are administered

  • AAHPERD Youth Fitness Test (1958)

  • National Children and Youth Fitness Study (1985, 1987)


References and cites l.jpg
References and Cites is done orally instead of in writing

Next Class is done orally instead of in writing

  • Tonight-intro and survey
