Case Studies

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Censoring Survival Data

Censoring Survival Data

Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Group Design

Group 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...

Interval Level of Measurement

Interval Level of Measurement

For effective statistical analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using the interval scale are similar to ordinal level data because they have a definite arrangement. However, in the interval level of measurement, the differences between data values are meaningful even though the data does not have a starting point.
Temperature is measured using the interval scale. It is measurable data, and the difference between...

Summary

This summary is machine-generated.

Partial interval recording (PIR) data can be misleading due to construct invalidity. New analysis methods are proposed to accurately interpret behavioral data from PIR, avoiding incorrect intervention inferences in research.

Background:

Partial interval recording (PIR) is a common behavioral measurement technique in single-case research.
PIR data is susceptible to construct invalidity, hindering accurate interpretation of behavioral characteristics.
Ignoring PIR's construct invalidity can lead to erroneous conclusions about intervention effectiveness.

Purpose of the Study:

To demonstrate how construct invalidity in PIR data can yield misleading research inferences.
To propose novel analytical methods for PIR summary measurements.
To enable accurate inferences about interpretable behavioral parameters using PIR data.

Main Methods:

Utilized an alternating renewal process model to represent the behavior under observation.
Simulated and analyzed PIR data, highlighting the impact of construct invalidity.
Developed and applied four distinct analytical methods to PIR summary measurements.

Main Results:

Demonstrated that ignoring PIR construct invalidity can lead to incorrect conclusions, such as misinterpreting intervention effects on undesirable behaviors.
The proposed analytical methods provide a means to draw valid inferences about underlying behavioral parameters.
Successfully applied the new methods to data from two single-case studies involving problem behavior.

Conclusions:

Construct invalidity is a significant issue in partial interval recording that requires careful consideration.
The proposed analytical methods offer a robust solution for analyzing PIR data more accurately.
These methods enhance the interpretability of behavioral research utilizing partial interval recording.
