The 2001 Child Behavior Checklist for Ages 6-18 (CBCL/6-18; formerly CBCL/4-18) has been updated to incorporate new normative data, include new DSM-oriented scales, and to complement the new preschool forms.

The CBCL/6-18 obtains reports from parents, other close relatives, and/or guardians regarding children’s competencies and behavioral/emotional problems. Parents provide information for 20 competence items covering their child's activities, social relations, and school performance. The CBCL/6-18 has 118 items that describe specific behavioral and emotional problems, plus two open-ended items for reporting additional problems. Parents rate their child for how true each item is now or within the past 6 months using the following scale: 0 = not true (as far as you know); 1 = somewhat or sometimes true; 2 = very true or often true.

The CBCL/6-18 scoring profile provides raw scores, T scores, and percentiles for three competence scales (Activities, Social, and School), Total Competence, eight cross-informant syndromes, and Internalizing, Externalizing, and Total Problems. The cross-informant syndromes scored from the CBCL/6-18, TRF, and YSR are Aggressive Behavior; Anxious/Depressed; Attention Problems; Rule-Breaking Behavior; Social Problems; Somatic Complaints; Thought Problems; and Withdrawn/Depressed. The six DSM-oriented scales are: Affective Problems; Anxiety Problems; Somatic Problems; Attention Deficit/Hyperactivity Problems; Oppositional Defiant Problems; and Conduct Problems. The scales are based on new factor analyses of parents’ ratings of 4,994 clinically referred children, and are normed on 1,753 children aged 6 to 18. The normative sample was representative of the 48 contiguous states for SES, ethnicity, region, and urban-suburban-rural residence. Children were excluded from the normative sample if they had been referred for mental health or special education services within the past year.

The ADM Ages 6-18 Module includes the CBCL/6-18, TRF, and YSR, enabling you to compare any combination of 8 forms per child. The CBCL/6-18 is also available in a newly revised Latino Spanish version.

For children too young for the CBCL/6-18, the Child Behavior Checklist/1½-5 (CBCL/1½-5/LDS) is used instead. Parents and other adults with close relationships to adults aged 18 to 59 can complete the Adult Behavior Checklist (ABCL).
