Summary
Probability sampling is superior to convenience sampling for accurately measuring public attitudes toward stuttering using the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S). This ensures generalizable results for specific geographic areas.
Area of Science:
- Speech and Language Pathology
- Public Health Research Methods
Background:
- Public attitudes toward stuttering are crucial for effective interventions.
- Accurate measurement of these attitudes is essential for research generalizability.
Purpose of the Study:
- To compare probability sampling with convenience sampling for measuring public attitudes toward stuttering.
- To evaluate the effectiveness of a Turkish translation of the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S).
Main Methods:
- A convenience sample of adults in Eskişehir, Turkey, was compared to two school-based probability cluster sampling schemes.
- The Public Opinion Survey of Human Attributes-Stuttering (POSHA-S) was administered to assess public attitudes.
Main Results:
- Probability samples yielded demographically distinct results compared to the convenience sample.
- Significant differences in POSHA-S subscores were observed between convenience and probability samples, indicating varied public attitudes.
Conclusions:
- Probability sampling is a more effective research strategy than convenience sampling for studies aiming to generalize findings to specific geographic areas.
- Researchers using the POSHA-S should consider probability sampling for more representative data on public attitudes toward stuttering.

02:16Surveys
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
00:55Convenience Sampling Method
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

01:04Social Facilitation
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.
02:16Stereotype Content Model
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
00:52Social Proof
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.
02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
