Background/Description
Inspiration is a complex phenomenon that has been studied by philosophers, psychologists, and artists for centuries. It is often described as a sudden feeling of insight or creativity, often accompanied by a sense of excitement and motivation. Inspiration can be triggered by a variety of things, such as a new experience, a work of art, or a conversation with another person.
Despite its importance, there is no single definition of inspiration that is universally accepted. However, most researchers agree that inspiration is a cognitive-emotional process that involves the interaction of several different factors, including:
- Creativity: Inspiration is often associated with creativity, as it is often the spark that ignites new ideas and insights.
- Motivation: Inspiration can also lead to increased motivation, as it can give people the energy and drive to pursue their goals.
- Emotion: Inspiration is also accompanied by a range of positive emotions, such as excitement, joy, and awe.
In 2003, Thrash and Elliot developed the Inspiration Scale (IS) to assess the frequency and intensity of inspiration experiences. The IS is a brief, self-report measure that consists of four items.
The IS has been shown to have good psychometric properties, including internal consistency, temporal stability, and measurement invariance across time and populations. It has also been shown to be a valid measure of inspiration, as it correlates with other measures of positive emotions, motivation, and creativity.
The IS is a valuable tool for researchers and clinicians alike. It can be used to assess individuals’ levels of inspiration, to track changes in inspiration over time, and to identify factors that promote and hinder inspiration.
Administration, Scoring and Interpretation
- Provide instructions to the participant. Explain to the participant that they are being asked to complete a brief questionnaire about their inspiration experiences.
- Hand the participant the IS questionnaire. The IS questionnaire can be administered in a variety of ways, such as in paper-and-pencil format, online, or through a mobile app.
- Ask the participant to complete the questionnaire. The participant should read each item carefully and answer both of the questions associated with each item.
- Collect the completed questionnaire. Once the participant has completed the questionnaire, collect it from them.
Reliability and Validity
The Inspiration Scale (IS) has been shown to have good reliability and validity.
Reliability refers to the consistency of a measure. In other words, a reliable measure will produce similar results when administered to the same person multiple times.
The IS has good internal consistency reliability, as measured by Cronbach’s alpha. Cronbach’s alpha is a measure of how closely related the items in a scale are to each other. A Cronbach’s alpha of 0.70 or higher is considered to be good reliability. The IS has a Cronbach’s alpha of 0.80, indicating that it has good internal consistency reliability.
The IS has also been shown to have good test-retest reliability. Test-retest reliability refers to the consistency of a measure over time. In other words, a measure with good test-retest reliability will produce similar results when administered to the same person twice, even if some time has elapsed between the two administrations.
A study by Thrash and Elliot (2003) found that the IS had a test-retest reliability of 0.79 over a two-week period. This indicates that the IS is a reliable measure of inspiration over time.
Validity refers to the extent to which a measure measures what it is intended to measure. In other words, a valid measure of inspiration will accurately measure the level of inspiration that a person experiences.
The IS has been shown to have good construct validity. Construct validity refers to the extent to which a measure correlates with other measures of the same construct. In other words, a measure with good construct validity will correlate with other measures of inspiration.
A study by Thrash and Elliot (2003) found that the IS correlated significantly with other measures of positive emotions, motivation, and creativity. This indicates that the IS is a valid measure of inspiration.
The IS has also been shown to have good discriminant validity. Discriminant validity refers to the extent to which a measure does not correlate with measures of other constructs. In other words, a measure with good discriminant validity should not correlate with measures of other constructs, such as anxiety or depression.
A study by Thrash and Elliot (2003) found that the IS did not correlate significantly with measures of anxiety or depression. This indicates that the IS has good discriminant validity.

Frequently Asked Questions
Q: What is the Inspiration Scale?
A: The Inspiration Scale (IS) is a brief, self-report measure of the frequency and intensity of inspiration experiences.
Q: Who developed the Inspiration Scale?
A: The Inspiration Scale was developed by Todd M. Thrash and Andrew J. Elliot in 2003.
Q: How is the Inspiration Scale scored?
A: The Inspiration Scale is scored by averaging the frequency and intensity scores for each item. The frequency and intensity scores are rated on a 7-point Likert scale.
Q: How is the Inspiration Scale interpreted?
A: The Inspiration Scale can be interpreted as follows:
- Low score (1-3): Low levels of inspiration
- Medium score (4-5): Medium levels of inspiration
- High score (6-7): High levels of inspiration
Q: What are the applications of the Inspiration Scale?
A: The Inspiration Scale can be used in a variety of research and clinical settings to assess individuals’ levels of inspiration, track changes in inspiration over time, and identify factors that promote and hinder inspiration.
Q: Is the Inspiration Scale reliable and valid?
A: Yes, the Inspiration Scale has been shown to have good reliability and validity.
