Brief Description

This is a self-administered, written-response questionnaire consisting of 150 statement-questions, designed to assess various aspects of an individual’s personality. Its purpose is to capture the respondent’s stance or attitude toward themselves across key psychological and social parameters such as self-esteem and self-image, general anxiety and stress, interpersonal relationships, communication skills, optimism or pessimism, emotional fluctuations, social adjustment, decisiveness and stability, as well as fears or phobic reactions.

Purpose

The aim of the questionnaire is to measure the degree of self-awareness and the nature of an individual’s self-perception, in order to identify key areas that may require improvement or further exploration. It contributes to personal development, psychological empowerment, and potentially professional support.

Scoring Method

The respondent is asked to evaluate themselves on each of the 150 statements using a seven-point Likert scale, ranging from 0 to 6. Responses are recorded on a special scoring sheet and graphically represented, forming a personal profile that visually reflects the individual’s overall self-image in relation to the assessed psychological dimensions.

Validity

The questionnaire has undergone pilot testing with a representative sample of adolescents and adults and has been examined for both content and construct validity. The results confirm that the tool’s individual dimensions clearly reflect the theoretical constructs being assessed, providing a valid means of capturing self-perception.

Reliability

The questionnaire’s reliability indicators are considered highly satisfactory. The internal consistency of the subscales (measured via Cronbach’s Alpha) shows high values, and test-retest measurements confirm the stability of results over time, reinforcing confidence in the tool’s use.

Data Analysis and Use

The data derived from the completion of the questionnaire can be utilized in various contexts, including personal introspection and development, counseling or psychological support, as well as educational or research study. The analysis of responses allows for the identification of both strong personality traits and areas of potential dysfunction, encouraging targeted intervention or further exploration.
