This component contains materials and the preregistration for the Year Long Longitudinal Study 2019.
# Original Study
## Preregistration
- Method Preregistration ([uploaded file][1] / [actual registration][2])
- Additional Behavior Items ([uploaded file][3] / [actual registration][4])
- Additional Virus Items ([uploaded files][5] / [actual registration][6])
- Booster / Extension Samples ([uploaded files][7] / [actual registration][8]) Note: completed after data collection for the first Booster sample wave was collected, but before the data was downloaded and processed.
## Materials
There are three surveys for the first wave. Each one is needed to recruit participants in proportion to their 2016 vote choice. The 3 wave 1 surveys are otherwise identical. After the first wave, only one survey was needed per wave.
- Wave 1 (Non-voters: [Word][9] / [Qualtrics][10])
- Wave 1 (Trump voters: [Word][11] / [Qualtrics][12])
- Wave 1 (Clinton voters: [Word][13] / [Qualtrics][14])
- Wave 2 ([Word][15] / [Qualtrics][16])
- Wave 3 ([Word][17] / [Qualtrics][18])
- Wave 4 ([Word][19] / [Qualtrics][20])
- Wave 5 ([Word][21] / [Qualtrics][22])
- Wave 6 ([Word][23] / [Qualtrics][24])
- Wave 7 ([Word][25] / [Qualtrics][26])
- Wave 8 ([Word][27] / [Qualtrics][28])
- Wave 9 ([Word][29] / [Qualtrics][30])
- Wave 10 ([Word][31] / [Qualtrics][32])
- Wave 11 ([Word][33] / [Qualtrics][34])
- Wave 12 ([Word][35] / [Qualtrics][36])
- Wave 13 ([Word][37] / [Qualtrics][38])
- Wave 14 ([Word][39] / [Qualtrics][40])
- Wave 15 ([Word][41] / [Qualtrics][42])
- Wave 16 ([Word][43] / [Qualtrics][44])
- Wave 17 ([Word][45] / [Qualtrics][46])
- Wave 18 ([Word][47] / [Qualtrics][48])
- Wave 19 ([Word][49] / [Qualtrics][50])
- Wave 20 ([Word][51] / [Qualtrics][52])
- Wave 21 ([Word][53] / [Qualtrics][54])
- Wave 22 ([Word][55] / [Qualtrics][56])
- Wave 23 ([Word][57] / [Qualtrics][58])
- Wave 24 ([Word][59] / [Qualtrics][60])
- Wave 25 ([Word][61] / [Qualtrics][62])
- Wave 26 ([Word][63] / [Qualtrics][64])
# Booster / Extension Samples
To more fully capture opinion dynamics over the course of the COVID19 pandemic, we collected additional data. First, a booster sample was collected to cover Wave 26 + 4 additional waves (closing near the end of June). Second, the original sample was re-recruited for an additional 4 waves (closing near the end of June).
- Wave 26 Booster (Non-voters: [Word][65] / [Qualtrics][66])
- Wave 26 Booster (Clinton-voters: [Word][67] / [Qualtrics][68])
- Wave 26 Booster (Trump-voters: [Word][69] / [Qualtrics][70])
- Wave 27 Booster ([Word][71] / [Qualtrics][72])
- Wave 27 Extension ([Word][73] / [Qualtrics][74])
- Wave 28 Booster/Extension ([Word][75] / [Qualtrics][76])
- Wave 29 Booster/Extension ([Word][77] / [Qualtrics][78])
- Wave 30 Booster/Extension ([Word][79] / [Qualtrics][80])
