Exam 10: Scale Construction: a Most Fundamental Tool

Identify a recommendation by Brown (2006) regarding confirmatory factor analysis (CFA) for cross-validation of a factor structure.

In sampling and data collection for scale construction, a researcher must ensure that:

Which of the following is a myth on scale construction?

In order for the definition of a construct of interest to be operationalized, the construct should be written in a statement that is measurable.

In the context of counseling research, which of the following is true of the measurement approaches based on the item response theory (IRT)?

Which of the following is true of using scales in different cultural contexts?

Identify a guideline suggested by DeVellis (2012) for developing scale items.

In the context of inclusion of both positive and negatively worded items in a scale, DeVellis suggested that the benefits of having opposite direction items outweighed the disadvantages.

Which of the following is a characteristic of exploratory factor analysis (EFA)?

The fundamental aim of factor analysis is to search for underlying psychological constructs seen in the common dimensions that underlie the original items or variables.

Translating and back-translating the items of a scale ensure the validity of the items or scale in another culture.

In the context of reliability estimates, coefficient alphas provide the researcher with information about the degree of the homogeneity or internal consistency among a set of items.

A criterion-referenced scale measures an individual's ability.

In scale construction, pilot testing provides a powerful tool for a researcher to identify items that might be misunderstood or unclear to the participants.

To enhance the construct validity of a scale, researchers are advised to conduct content analyses and consult with domain experts and to pilot items to identify potential problems with their wording.

According to Kline (2005), when conducting exploratory factor analysis (EFA) for new scale development, principal components analysis (PCA) provides a more realistic estimation of factor structure assuming that "the items are measured with errors."

According to Cohen, Swerdlik, and Phillips (1996), the _____ refers to an indication of how much variance is shared by two variables.

_____ examines the interrelationships among a large number of items or variables and condenses that information into a smaller set of common underlying dimensions.

The _____ of a scale can be established by providing a low correlation coefficient between two measures.

The process of item generation in scale construction is highly linear.
