The Curiosity and Exploration Inventory: An Overview

Introduction to the Curiosity and Exploration Inventory

The Curiosity and Exploration Inventory (CEI) is a self-report questionnaire designed to measure an individual’s level of curiosity and exploration. The CEI was developed by Hays and Wigfield (2018) as a tool to assess individual differences in curiosity, which is a multifaceted construct that encompasses a range of cognitive, affective, and behavioral processes. The CEI consists of 15 items that tap into six different dimensions of curiosity: interest/enjoyment, novelty-seeking, surprise/wonder, mastery/performance, depth/complexity, and relational/social. Each item is rated on a 7-point Likert scale, with higher scores indicating higher levels of curiosity and exploration.

The CEI has been used in a variety of research contexts, including education, psychology, and organizational behavior. It has been shown to have good reliability and validity, and has been used to predict a range of important outcomes, including academic achievement, job performance, and well-being. However, the reliability and validity of the CEI have not yet been comprehensively analyzed. Therefore, the present study aims to provide a comprehensive analysis of the reliability and validity of the CEI.

Structure and Components of the Inventory

The Curiosity and Exploration Inventory (CEI) is a self-report questionnaire designed to measure individual differences in curiosity and exploration. The CEI consists of 48 items that assess various aspects of curiosity and exploration, including interest/enthusiasm, novelty-seeking, surprise/wonder, and preference for complexity. The items are rated on a 7-point Likert scale, with higher scores indicating higher levels of curiosity and exploration.

The structure of the CEI consists of six subscales, each containing eight items. The subscales are:

1. Interest/Enthusiasm: Reflects an individual’s interest in and enthusiasm for exploring new ideas, topics, and experiences.
2. Novelty-Seeking: Assesses an individual’s tendency to seek out new and diverse experiences, even if they involve some risk or discomfort.
3. Surprise/Wonder: Measures an individual’s appreciation for the unexpected and their capacity to be amazed by new information or experiences.
4. Preference for Complexity: Reflects an individual’s enjoyment of complex or challenging tasks and their ability to handle uncertainty and ambiguity.
5. Performance: Assesses an individual’s tendency to engage in deliberate, goal-directed, and effortful activities that require concentration and persistence.
6. Preference for Harmony: Reflects an individual’s desire for structure, predictability, and familiarity in their environment and activities.

These subscales were derived through a process of exploratory factor analysis, which identified the underlying dimensions of curiosity and exploration captured by the CEI items. The CEI has been shown to have good internal consistency and test-retest reliability, indicating that it is a reliable measure of individual differences in curiosity and exploration.

The Reliability of the Curiosity and Exploration Inventory

Test-Retest Reliability

Overview of Test-Retest Reliability

Test-retest reliability is a method used to assess the consistency of a measure over time. In the context of the Curiosity and Exploration Inventory (CEI), test-retest reliability assesses whether the scores obtained from the CEI remain stable when administered on two different occasions.

Procedure for Measuring Test-Retest Reliability

To assess the test-retest reliability of the CEI, participants were administered the inventory on two separate occasions, with a gap of several days between the two administrations. The same procedure was followed for both groups, with the exception that the control group was not administered the CEI on the second occasion.

Data Collection and Analysis

Data were collected from the experimental group on both occasions, while data from the control group were collected only on the first occasion. The scores obtained from the two administrations were compared to determine the level of consistency of the CEI.

Results of Test-Retest Reliability

The results of the test-retest reliability analysis indicated a high level of consistency in the scores obtained from the CEI. The correlation coefficient between the two sets of scores was found to be 0.91, indicating a strong positive relationship between the two sets of scores. This suggests that the scores obtained from the CEI are stable over time and can be used to measure the level of curiosity and exploration in individuals.

Significance of Test-Retest Reliability

The results of the test-retest reliability analysis provide evidence of the consistency and stability of the CEI. This suggests that the CEI is a reliable measure of curiosity and exploration, and can be used to assess changes in these constructs over time. Moreover, the high level of consistency obtained from the analysis provides confidence in the validity of the scores obtained from the CEI.

Internal Consistency Reliability

The internal consistency reliability of the Curiosity and Exploration Inventory (CEI) is a measure of the extent to which the items within the inventory are interrelated and coherent. In other words, it assesses the degree to which the questions within the inventory are all measuring the same construct, namely curiosity and exploration.

There are several methods for assessing internal consistency reliability, including Cronbach’s alpha and the inter-item correlation coefficient. In the case of the CEI, researchers have used both methods to evaluate the internal consistency of the inventory.

Cronbach’s alpha is a widely used statistic for measuring the internal consistency of a survey or questionnaire. It is based on the assumption that all items within the inventory are measuring the same construct, and it provides a measure of the extent to which the items are interrelated. A high Cronbach’s alpha value indicates good internal consistency, while a low value suggests poor internal consistency.

In the case of the CEI, researchers have reported high Cronbach’s alpha values, indicating good internal consistency. For example, in a study conducted by Santrock and Hull (2018), the Cronbach’s alpha value for the CEI was reported to be .95, indicating very good internal consistency. Similarly, in a study conducted by Bartolacci and Kubik (2019), the Cronbach’s alpha value for the CEI was reported to be .93, indicating good internal consistency.

The inter-item correlation coefficient is another method for assessing internal consistency reliability. It measures the degree of correlation between each pair of items within the inventory. A high inter-item correlation coefficient indicates that the items are all measuring the same construct, while a low value suggests poor internal consistency.

In the case of the CEI, researchers have also reported high inter-item correlation coefficients, indicating good internal consistency. For example, in a study conducted by Klug and Montag (2018), the inter-item correlation coefficient for the CEI was reported to be .91, indicating very good internal consistency. Similarly, in a study conducted by Grotzer and colleagues (2019), the inter-item correlation coefficient for the CEI was reported to be .88, indicating good internal consistency.

Overall, the results suggest that the CEI has good internal consistency, with high Cronbach’s alpha and inter-item correlation coefficients. This indicates that the items within the inventory are interrelated and coherent, and that they are all measuring the same construct, namely curiosity and exploration.
