Psicometría: Modelo unidimensional y de factores correlacionados

Understanding Unidimensional and Correlated Factor Models

Overview of Instrument Models

• The discussion begins with the distinction between unidimensional models (single dimension) and correlated factor models (multiple factors), which are common in psychological assessments.

• Examples of unidimensional scales include workload assessment and general well-being scales, highlighting their widespread use.

Correlated Factors in Emotional Dependency

• A specific example of a correlated factor model is emotional dependency, which includes factors such as fear of loneliness, boundary expression, attention-seeking behavior, and psychological well-being dimensions like acceptance and self-control.

• Other dimensions mentioned include autonomy, social connections, and project management skills within the context of emotional dependency.

Clarification on Model Types

• It is emphasized that the discussed model should not be confused with a bifactor model; instead, it is referred to simply as a two-factor correlated model or a three-factor correlated model for clarity.

• The speaker stresses the importance of using precise terminology when discussing these models to avoid confusion in future discussions.

Future Discussions on Bifactor Models

• The session concludes with an indication that subsequent lessons will cover bifactor or second-order models in more detail.
