Version V1


The Head Start Miami-Dade County, 2014-2015 study seeks to validate a novel computerized measure of motivation orientation among 350 low-income preschoolers served by the Head Start program. To address the lack of developmentally appropriate and reliable measures of motivation orientation, a Computer Administered Battery of Observable Motivation (CABoOM) was developed. CABoOM consists of three tasks (sling shot, escape the grid, and memory matching) ranging in solvability and level of difficulty. The assessments were collected twice in the spring, once on the full sample and a second time within two weeks on a subset of the sample. Direct assessments of school readiness outcomes such as children's language and science abilities were collected, along with a teacher rating scale of approaches to learning in order to allow for the examination of gains across the year.

Study Purpose

This study aimed to address the lack of developmentally appropriate and reliable measures of motivation orientation for young children. In pursuit of this aim, a computer-based direct assessment of motivation orientation was developed. The study assessed the test reliability and the response process validity of CABoOM, as well as, concurrent and predictive validity by examining associations with approaches to learning and gains in school readiness outcomes from the beginning to the end of the Head Start year.

Study Design

Assessments took place over two sessions within a week. During the first session all participants completed a pretest version of all three tasks to establish a baseline ability. They were also given pictures of two puzzles and asked to identify which puzzles were easier and which were harder in order to test for response process validity. The respondents were then administered each task (sling shot, escape the grid, and memory matching game) 7 times with ranging solvability and difficulty. Throughout the process each child was allowed to retry 'failed' tasks or determine the level of difficulty for the next task. The same method was used to collect data in the second session however, only a subset of the sample was assessed.


The final sample consist of 316 children, across 35 classrooms, in 9 Head Start Centers. Mean age of children was 51.38 months (range=37.9 to 62.7) and 52.5 percent of children were female (n=166). The retest sample consists of 60 children randomly selected after stratifying for age and gender. Mean age of children was 52.7 months (range-40.7 to 61.6) and 55 percent of children were female (n=33). Data was collected during the 2014-2015 school year.

Version History

2017-06-14 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.


  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
