This dataset contains all longitudinal data for the entirety of the WRRMP. This includes 10 waves worth of twin data, with extensive reading, math, behavioral, and environmental measures. Due to the twin nature of the data, data is presented as both long and wide, with each twin represented twice within the dataset.
This dataset contains results from the initial survey assessment completed by parents and twins (who were 9 years or older) regarding the twin pair's environments and behaviors (2010). T
This dataset contains results from the third wave of surveys sent to parents of twin pairs in 2016. In these surveys, parents were asked to rate themselves, their home, and their twins on various questionnaire measures including: family demographic measures (parent education, household income, etc.), home environmental measures (home literacy environment, family routines, CHAOS, etc.), family history (Colorado Learning Disabilities Questionnaire), and various behavioral measures (ADHD ratings, internalizing and externalizing behaviors, executive function, etc).
This dataset contains results from the second wave of surveys sent to parents of twin pairs in 2014. Within said surveys, parents were asked to rate themselves, their home, and their twins on various questionnaire measures including: family demographic measures (parent education, household income, etc.), home environmental measures (home literacy environment, family routines, CHAOS, etc.), family history (Colorado Learning Disabilities Questionnaire), and various behavioral measures (ADHD ratings, internalizing and externalizing behaviors, executive function, etc).
This dataset contains results from the first wave of surveys sent to parents of twin pairs in 2012.
These data are for each item on all achievement and behavioral assessments completed during the original intervention projects. The dataset is wide, with separate variable names for each wave of assessment. All participants (n= 4,038) are included. These data can be linked to the "total level" data using the PK_ID variable.
These data represent a combined dataset of Drs. Stephanie Al Otaiba and Carol Connor's RCT projects. Therefore, these data are not unique, in that the original investigators may have shared the individual datasets in other places that we are not aware of.
