The CBCL includes competence items to assess a child’s adaptive functioning and positive behaviors. These items evaluate participation in activities, social interactions, and academic performance. Parents or caregivers rate the child’s competence on a scale, providing insights into their strengths and areas for support. The competence items are divided into categories such as activities, social, and school functioning, offering a comprehensive view of the child’s abilities. This section helps identify positive behaviors that may serve as strengths, distinguishing them from problem behaviors. The results are compared to normative samples, aiding in understanding the child’s developmental and functional status. This assessment is crucial for holistic evaluation and intervention planning.
Problem items
The CBCL includes problem items to identify behavioral and emotional difficulties in children. These items assess a wide range of issues, such as anxiety, aggression, and hyperactivity. Parents or caregivers rate each item on a 0- to 2-point scale, indicating the severity of the problem. The problem items are categorized into internalizing (e.g., anxiety, withdrawal) and externalizing (e.g., aggression, delinquency) domains. The CBCL/6-18 contains 120 problem items, providing a comprehensive evaluation of potential issues. This section helps identify patterns of behavior that may require intervention. By comparing scores to normative data, professionals can determine if behaviors fall within typical or clinical ranges, aiding in diagnosis and treatment planning.
Syndrome scales
The CBCL includes eight syndrome scales, which are empirically derived groupings of problem items. These scales assess specific behavioral patterns, such as Anxious/Depressed, Withdrawn/Depressed, and Aggressive Behavior. Each scale aggregates related items to provide a clearer understanding of a child’s behavioral profile. Scores on these scales help identify patterns of behavior that may indicate emotional or psychological difficulties. The syndrome scales are based on factor analysis and are designed to reflect common behavioral syndromes observed in children. They are widely used in clinical and research settings to guide diagnosis, treatment planning, and ongoing assessment of behavioral changes over time. These scales enhance the utility of the CBCL in understanding childhood behavioral challenges comprehensively.

DSM-oriented scales
The CBCL includes six DSM-oriented scales, designed to align with diagnostic categories from the Diagnostic and Statistical Manual of Mental Disorders (DSM). These scales assess behaviors associated with specific disorders, such as Attention-Deficit/Hyperactivity Problems, Anxiety Problems, and Conduct Problems. Each scale consists of items that reflect symptoms consistent with DSM criteria, providing a link between behavioral assessments and potential diagnoses. These scales are particularly useful for clinicians to identify areas of concern that may warrant further evaluation. The DSM-oriented scales enhance the CBCL’s clinical utility by offering a framework for understanding behavioral issues within a diagnostic context.

The measure is intended for children aged 6-18 years, and the administrator should ideally have regular interaction with the child to provide reliable data. This ensures the responses reflect the child’s typical behavior and emotional functioning accurately.
Scoring system and interpretation
The CBCL uses a 3-point Likert scale to rate the frequency or severity of each behavior, with scores ranging from 0 (not true) to 2 (very true or often true). The measure includes competence items, which assess positive behaviors, and problem items, which identify behavioral or emotional difficulties. Scores are compared to age- and gender-specific normative data, allowing for standardized interpretation. High scores on problem items may indicate significant behavioral or emotional challenges, while low scores on competence items suggest difficulties in social, academic, or personal functioning. The CBCL provides profiles that categorize scores into normal, borderline, or clinical ranges, aiding clinicians in identifying areas of concern and guiding intervention strategies. This systematic approach ensures reliable and consistent assessment of child behavior.
Normative data and clinical ranges
The CBCL uses normative data based on large, representative samples of children, stratified by age and gender, to provide standardized comparisons. Scores are categorized into normal, borderline, and clinical ranges, with clinical ranges indicating behaviors more common in referred samples. High scores on problem items or low scores on competence items suggest potential difficulties. Normative data helps identify whether a child’s behavior is within typical ranges or may require further evaluation. Clinical ranges are derived from empirical data, ensuring reliable interpretation. This system allows clinicians to assess severity and monitor changes over time, making the CBCL a valuable tool for both assessment and treatment planning.
