Definition

The Behavior Assessment System for Children: Second Edition is a series of instruments designed to help aid in the diagnosis and treatment of children, adolescents, and young adults between the ages of 2 and 25.

Description

The Behavior Assessment System for Children: Second Edition (BASC-2) is a series of instruments for children, adolescents, and young adults between the ages of 2 and 25. The BASC-2 system has Parent Rating Scales (PRS), Teacher Rating Scales (TRS), Self-Report of Personality (SRP and SPR-I), a Structured Developmental History (SDH), and a Student Observation System (SOS). The TRS, PRS, and SRP have multiple forms for different age groups. In addition to these forms, the BASC-2 has a Parenting Relationship Questionnaire (PRQ) that assesses the relationships between the child and his/her caregiver(s). The forms are available in English and in Spanish [1, 2].

The BASC-2 TRS and PRS were written to be at the sixth grade reading level and can be completed by the raters in under 20 minutes. The SRP was written at the second grade reading level and can be completed in approximately 30 minutes. On the BASC-2 TRS and PRS, teachers and parents rate how often the examinee’s behavior and symptoms occur on a four point rating scale ranging from Never (N) to Always (A). On the BASC-2 SRP, examinees rate their behavior on the same four point rating scale, as true/false, or as yes/no, depending on the age group [1, 4].

Scales

The items on each form of the BASC-2 can be used to calculate a variety of scales designed to assess for adaptive functioning and for symptoms of psychopathology [3]. Additionally, each form contains validity indices that assess how the rater approached the test.

The items on the TRS and PRS can be used to calculate five composite scales: Adaptive Skills, a Behavioral Symptoms Index, Externalizing Problems, Internalizing Problems, and School Problems. The items can also be used to calculate 16 Clinical and Adaptive Scales and seven Content Scales. The Content Scales can only be calculated by using the scoring software and cannot be calculated by hand [1].

The items on the SRP can also be used to calculate five composite scales: The Emotional Symptoms Index, Inattention/Hyperactivity, Internalizing Problems, Personal Adjustment, and School Problems. In addition to these composite scales, the items on the SRP can be used to calculate 18 Clinical and Adaptive Scales and seven content scales [1].

Scoring

The BASC-2 can be scored either by hand in approximately 30 min or by using the ASSIST Plus software profile. The raw scores are transformed into T scores and percentiles [1, 2].

Psychometric Properties

The BASC-2 was standardized on samples from the United States between 2002 and 2004. The standardization samples for each of the instruments (TRS, PRS, and SRP) were large, ranging from 3,400 (SRP) to 4,800 (PRS). The sample used was representative of the population of the United States at the time of standardization for race, sex, geographic region, and parent’s socioeconomic status. The internal consistency of the BASC-2 instruments is adequate ranges from 0.67 to 0.97. Similarly, the test-retest reliability is good, ranging from 0.56 to 0.99 [1].

Relevance to Childhood Development

The BASC-2 can be used to evaluate children for the presence of psychopathology.
