Questionnaire Description

The Conners-28 questionnaire is designed to describe problematic behaviors as assessed by parents and teachers. The evaluation is conducted using a four-point scale, where responses range from “Not at all” to “Very much.” The tool is applied in both research and clinical settings, contributing to the identification of symptoms associated with disorders such as ADHD.

Data Analysis and Use

The general population sample consisted of 31 primary schools from various regions across Greece and is considered nationally representative. The clinical sample consisted of 861 children referred to child psychiatric and psychological services, with a total of 1,733 completed questionnaires. Of these, 881 came from the general population and 852 from the clinical sample. Statistical analysis showed that, despite minor differences in the scale’s subcomponents, the factors found in the American sample are also validated in the Greek population. The tool successfully distinguishes between children from the general population and those from clinical samples, confirming the reliability of the Conners scale as an instrument for epidemiological studies and its structural stability in cross-cultural research.

Purpose

The purpose of the questionnaire is to identify problematic behaviors in children as observed by parents and teachers. Its use supports early intervention and targeted assessment in preventive or therapeutic contexts.

Scoring

Scoring is based on a four-point scale: 1 (Not at all), 2 (Seldom), 3 (Quite often), and 4 (Very much). Data analysis shows that the scores have good internal consistency and validity, making the tool reliable for diagnostic use.
