Tool-Description

The Adolescent Systemizing Spectrum Quotient (SQ-55) – Parent Version is a psychometric tool designed to assess the level of systemizing in adolescents aged 12-15 years, based on observations made by their parents. Systemizing refers to an individual’s ability to identify, understand, and predict patterns and systems, an ability often associated with the autism spectrum.
The SQ-55 consists of 55 questions that cover various aspects of systemizing, such as:
The adolescent’s interest in understanding systems (e.g., machines, computer programs, numerical systems).
Their preference for activities that require categorization, organization, or structured logic.
The degree to which the adolescent exhibits behaviors related to analyzing and understanding details in everyday situations.

Data Analysis and Usage

The data collected from the SQ-55 – Parent Version can be analyzed to evaluate the level of systemizing in the adolescent. Parents are asked to rate, using a Likert-type scale, the intensity or frequency with which the adolescent exhibits specific behaviors or interests.
The analyses conducted include:
Reliability analysis to calculate the internal consistency of the responses, using the Cronbach’s alpha coefficient.
Factor analysis to identify the main dimensions that make up systemizing.
Correlation analysis with other variables, such as social skills or cognitive flexibility, to understand the relationship between systemizing and other psychological characteristics.
The data obtained can be used in research and clinical settings to understand the role of systemizing in adolescent development.

Purpose

The primary goal of the Adolescent Systemizing Spectrum Quotient (SQ-55) – Parent Version is to assess the level of systemizing in the adolescent, based on their parents’ perceptions. This tool helps:
Identify high levels of systemizing, which may be indicative of characteristics associated with the autism spectrum.
Understand how systemizing affects the daily life and development of adolescents.
Develop educational and therapeutic interventions that can support adolescents with pronounced systemizing characteristics.

Calibration

The calibration of the SQ-55 – Parent Version involves the following steps:
Reliability analysis to ensure the consistency of parents’ responses across different items on the scale.
Confirmatory factor analysis to validate the dimensions of the questionnaire.
Cross-validation with different populations to ensure the tool’s generalizability and validity across various groups of adolescents.
