Project
Description: This LDbase project page containes the open science materials for our meta-analysis on the reading anxiety and reading achievement.
Dataset
Part of Project: Project KIDS
Description: This data set includes all total scores, demographics, home literacy environment, etc. for Project KIDS. Data are in wide format, with separate variables for each wave of assessments. All 4038 participants are represented in the data.
Dataset
Part of Project: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data are descriptive codes for the studies included in the meta-analysis. There are 31 studies. Data are presented in wide format. There are 34 variables.
Dataset
Part of Project: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data represent effect sizes comparing children with NSCP/L to non-cleft peers. There are 241 effect sizes from 31 studies. Children's ages ranged from 13-months to 104-months (8;7). The data are in long format as there were multiple effect sizes extracted per study.
Dataset
Part of Project: Speech and language skills in children with nonsyndromic cleft palate with or without cleft lip
Description: These data are from our third meta-analysis project. The speech-vocabulary analysis represented eight samples and the speech-mlu analysis represented four samples. The ages ranged from 18-months to 39-months.

Description: Data for student participants including achievement data and demographics. Dataset is in wide format.
Dataset
Part of Project: Reading RULES! Kindergarten (RRK)
Description: These data are for teachers in the RRK study who were randomized to a treatment or control condition.
Dataset
Part of Project: Project KIDS
Description: These data include information on family demographics, home environment, health information, child diet and nutrition, BRIEF, SWAN, all at the item level. This is cross-sectional data. Data can be linked to other Project KIDS data through the PK_ID variable.
Dataset
Part of Project: Reading Anxiety and Reading Achievement: A Meta-Analysis
Description: This is a spreadsheet format of table 4 that is included in the manuscript. Table 4 reports the reading anxiety measure used in each of 44 studies included in the reading anxiety meta-analysis.
Dataset
Part of Project: Reading Anxiety and Reading Achievement: A Meta-Analysis
Description: This is a spreadsheet format of table 3 that is included in the manuscript. Table 3 reports the study quality of the studies included in the reading anxiety meta-analysis. 14 quality indicators were selected from a suggested list by Protogerou and Hagger (2020) and adapted slightly in some cases to fit our current meta-analysis topic.
Dataset
Part of Project: Reading Anxiety and Reading Achievement: A Meta-Analysis
Description: This is the data that was extracted from existing studies for use in this meta-analysis on reading anxiety and reading achievement. This includes 44 studies. Many of the studies had multiple effect sizes. Each row of data represents a effect size (long format).
Dataset
Part of Project: Project KIDS
Description: 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.
