Description

The Thinking Styles Inventory [TSI-104] is a 104-item questionnaire designed to assess individuals’ preferences regarding how they think, organize their thoughts, and approach different situations. It is based on Sternberg’s theory of mental self-government and uses a seven-point response scale.

Purpose

The main purpose of the TSI-104 is to identify and understand an individual’s preferred thinking styles. According to Sternberg’s theoretical framework, thinking styles influence the way people process information, solve problems, and collaborate with others. They are not equivalent to intellectual abilities, but rather reflect preferences in how those abilities are used.

Assessing thinking styles may contribute to greater self-awareness and may support improvements in learning, communication, and professional or social functioning.

Structure and Scoring

Each statement is rated from 1 to 7, depending on the participant’s degree of agreement or disagreement. Responses are organized into five main groups of thinking styles:

Functions: Legislative, Executive, Judicial.

Forms: Monarchic, Hierarchic, Oligarchic, Anarchic.

Levels: Global and Local.

Scopes: Internal and External.

Leanings: Liberal and Conservative.

The mean score for each style is used to identify the individual’s dominant thinking preferences.

Validity

According to the available material, full validity studies have not yet been completed for a Greek sample. However, international studies have reported associations between thinking styles and variables such as academic performance, personality, and well-being, while factor analyses have provided support for key dimensions of Sternberg’s theory.

Reliability

International findings report internal consistency coefficients for the subscales ranging approximately from 0.64 to 0.89, with an average of around 0.75, indicating satisfactory internal consistency. A complete reliability evaluation for the Greek population has not yet been completed.

Data Analysis and Use

Data analysis is mainly based on calculating the mean score for each thinking style. The results can be used to describe an individual’s preferred cognitive profile and may be applied in research, educational, and professional contexts.

The TSI-104 may be useful in differentiated instruction, career guidance, and psychoeducational interventions.
