Peabody Treatment Progress Battery (PTPB); Bickman et al., 2010) The Peabody Treatment Progress Battery (PTPB) is a set of 11 measures designed to assess mental health outcomes and clinical processes in youth ages 11-18. The information is collected from youth, caregivers, and clinicians, and the measures are appropriate for use as screening tools and for monitoring symptom changes over time (Riemer et al., 2012). The PTPB is intended for use in service settings such as individual outpatient, foster care, and in-home treatment (Bickman et al., 2010). The measures within the PTPB are brief, ranging from 2 to 26 items, and can be administered in just five to eight minutes (Bickman et al., 2010). The first six measures focus on treatment outcomes, while the latter five measures focus on treatment processes such as therapeutic alliance and treatment expectation (Riemer et al., 2012). The first six measures are also sensitive to symptom changes due to treatment (Riemer et al., 2012).
