Type of Study: Pretest–posttest study with a nonequivalent control group (Quasi-experimental)
Number of Participants: 28

Population:

  • Age — Mean=12.39 years
  • Race/Ethnicity — 12% Caucasian/White, 10% Multi-Racial, 3% African America/Black, 3% Native American, and 1% Hispanic/Latinx

  • Status — Participants were youth in a long-term inpatient residential program.

Location/Institution: Midwestern region of the United States

Summary: (To include basic study design, measures, results, and notable limitations)
The purpose of the study was to estimate the degree of therapeutic equivalence between the Developmental Trauma and Attachment Program (DTAP) and its abbreviated counterpart (DTAP-A). Participants received either DTAP or DTAP-A. Measures utilized include the UCLA Post-traumatic Stress Disorder Reaction Index (PTSD-RI) and the Behavior Assessment System for Children, Third Edition (BASC). Results indicate that scores on the PTSD-RI and BASC did not identify any statistical or practical significance between DTAP and DTAP-A program completers’ self-reported treatment gains. However, DTAP program completers tended to report clinically significant changes in posttraumatic stress disorder and personal adjustment to greater degrees when compared to those completing the DTAP-A protocol. Limitations include the small sample size, the sample was associated with a single long-term treatment facility, and the lack of controlled postintervention follow-up.

Length of controlled postintervention follow-up: None.

The purpose of the study was to inspect the degree of symptom improvement associated with the Developmental Trauma and Attachment Program (DTAP) for decreasing symptoms of posttraumatic stress disorder (PTSD) among youth in residential treatment following complex trauma scenarios associated with domestic and international adoption/foster care. Participants received the DTAP intervention. Measures utilized include the PTSD Reaction Index (PTSD-RI) and UCLA PTSD Reaction Index. Results indicate statistically significant decreases in symptoms from admission to discharge associated with medium-effect sizes across PTSD symptoms. Nearly one in three participants reported clinically significant changes associated with treatment, whereas two in five reported improvements but not in the clinically significant range. Female participants reported greater decreases in negative cognitions; however, no other differences in treatment response based on participant characteristics were detected. Limitations include the lack of a control group and that the measurement of study outcomes was based solely on scores from the PTSD-RI. Note: This article was not used in the rating process due to the lack of a control group.

The purpose of the study was to inspect the degree of symptom improvement associated with the Developmental Trauma and Attachment Program (DTAP) for decreasing disruptive behavior symptoms among youth in residential treatment following traumatic experiences within domestic and international adoption and foster care systems. Participants received the DTAP intervention. Measures utilized include the Behavior Assessment System for Children-Third Edition (BASC–3) and the Strengths and Difficulties Questionnaire (SDQ). Results indicate statistically significant decreases in disruptive behavior symptoms from admission to discharge associated with small and medium effect sizes. Nearly one in four participants reported clinically significant changes associated with treatment, with about one in three reporting improvements, but not within the clinically significant range. Limitations include the small sample size, lack of a control group, and reliance on self-report measures. Note: This article was not used in the rating process due to the lack of a control group.
