Purpose of the Questionnaire

The ITEBS scale is primarily designed to evaluate the interaction between cognitive processes (thinking), emotions, and behavior. It is intended for both adults and adolescents and is used in psychotherapeutic and counseling contexts. Its goal is to measure how thoughts influence emotions and behavior, as well as how emotions and behavior, in turn, affect thoughts.

Questionnaire Analysis

The scale was developed in 2018 by a team of cognitive-behavioral psychologists, based on the Cognitive Triad model. It consists of 15 statements that capture the interaction between thought, emotion, and behavior. Respondents are asked to indicate the degree of agreement with each statement. The scale includes three subscales: Cognitive Influence, Emotional Reaction, and Behavioral Expression, each comprising 5 questions.

Question Scoring

Each item is rated on a five-point Likert scale:
1 = “Strongly disagree,”
2 = “Disagree,”
3 = “Neither agree nor disagree,”
4 = “Agree,”
5 = “Strongly agree.”
The total score ranges from 15 to 75, with higher values indicating greater correlation and harmony between thought, emotion, and behavior.

Statistical Analysis

The scale has an overall internal consistency index of Cronbach’s α = 0.82. Each subscale ranges from 5 to 25.
Cognitive Influence expresses the extent to which thoughts affect emotions and behavior.
Emotional Reaction describes the influence of emotion on thought and action.
Behavioral Expression evaluates how behaviors are influenced by emotions and thoughts.
High scores in a subscale indicate a stronger influence of that particular dimension on the others.

Validity of the Questionnaire

The ITEBS scale has been validated through correlations with existing standardized scales such as the DASS-21 and the Cognitive Fusion Questionnaire. It has been used in various Greek and international studies, showing positive results regarding discriminant, concurrent, and construct validity.

Reliability of the Questionnaire

The reliability of the scale has been documented with a Cronbach’s Alpha ranging from 0.78 to 0.85 for the subscales, and 0.82 overall. A test–retest within a two-week interval demonstrated stability of results with a correlation of r = 0.74.
