The Preschool Behavior Questionnaire [PBQ-39]

Brief Description

The Preschool Behavior Questionnaire (PBQ) is based on Rutter’s Behavior Questionnaire (1967) and was developed by L. Behar in 1977. It is a clinical assessment tool consisting of 36 items that evaluate emotional and behavioral problems in preschool-aged children. The PBQ is designed to detect early signs of disorders and is used both in typical populations and in high-risk groups.

Purpose

The PBQ aims to provide a clinical assessment of emotional and behavioral problems in preschool-aged children. It is particularly sensitive to detecting changes in a child’s behavior, thereby facilitating the early identification of psychological difficulties or disorders.

Scoring Method

The questionnaire consists of 36 statements that are evaluated by the teacher or caregiver based on the frequency of the observed behavior. The responses are divided into three distinct domains: (a) emotional problems, (b) extroverted-aggression, and (c) anxiety-fear. The total score offers an overall picture of the child’s emotional and behavioral condition.

Validity

The conceptual validity of the PBQ is supported through correlations with other assessment tools. These correlations with validated measures indicate good construct validity, making it appropriate for use in preschool populations.

Reliability

The reliability of the PBQ is considered satisfactory, both in terms of internal consistency and test-retest reliability. Internal consistency is confirmed by high evaluation index scores, while repeated assessments yield stable results.

Data Analysis and Use

Data from the PBQ can be analyzed based on the three dimensions it evaluates, allowing for the identification of behavioral profiles. The results can be used for individual monitoring of children as well as for research purposes in preschool populations. Evaluation is typically conducted by mental health professionals or educators and can support the design of interventions.
