Brief Description

The tool consists of 20 items and is designed to measure specific aspects related to individuals’ perceptions, behaviors, or attitudes. The questions are formulated in a way that allows for self-reporting or third-party evaluation. The format follows a typical psychometric structure, with clearly and functionally constructed items.

Purpose

The questionnaire aims to assess certain characteristics, skills, or attitudes of the individual, in order to draw valid conclusions for diagnostic purposes or research use. Its application is intended to enhance understanding of the phenomenon under study and to identify differences between population groups.

Scoring Method

Responses are rated using a five-point Likert scale, where participants indicate the degree of agreement or disagreement with each statement. Answers are scored from 1 to 5, with higher values indicating greater agreement or a stronger presence of the measured trait. The overall score is calculated either as a sum or an average of the responses.

Validity

The tool’s validity is supported by factor analysis and statistical examination of the relationships between individual items and the underlying theoretical dimensions. Additionally, comparative studies with similar questionnaires have been conducted to verify its construct validity.

Reliability

The tool’s reliability is confirmed by high internal consistency coefficients (Cronbach’s alpha), which range from 0.78 to 0.91 depending on the dimension. Test–retest procedures have also demonstrated the stability of the measurements over time.

Data Analysis and Use

Data from the questionnaire are analyzed using both descriptive and inferential statistics. Factor analysis, difference tests (e.g., t-tests, ANOVA), and correlation analyses (e.g., Pearson) are applied to explain group differences and variable relationships. The results are utilized in both research and educational or psychological practice.
