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]) [1]: https://osf.io/65mwg/ [2]: https://osf.io/7h5ds [3]: https://osf.io/fjzqv/ [4]: https://osf.io/rxcqf [5]: https://osf.io/8ankm/ [6]: https://osf.io/7r4bk [7]: https://osf.io/u4zk7/ [8]: https://osf.io/u3dj6 [9]: https://osf.io/dj23h/ [10]: https://osf.io/eu6js/ [11]: https://osf.io/r4qzb/ [12]: https://osf.io/4e8hs/ [13]: https://osf.io/yhabu/ [14]: https://osf.io/k48cn/ [15]: https://osf.io/3sb7q/ [16]: https://osf.io/rd94n/ [17]: https://osf.io/j2dp6/ [18]: https://osf.io/crdv4/ [19]: https://osf.io/n6pmz/ [20]: https://osf.io/zsu84/ [21]: https://osf.io/4xuam/ [22]: https://osf.io/9m6ge/ [23]: https://osf.io/8ge3u/ [24]: https://osf.io/u7mg6/ [25]: https://osf.io/gsnye/ [26]: https://osf.io/n8td2/ [27]: https://osf.io/2jf3r/ [28]: https://osf.io/aw7q4/ [29]: https://osf.io/4u86t/ [30]: https://osf.io/3erbu/ [31]: https://osf.io/49m8a/ [32]: https://osf.io/rpzkf/ [33]: https://osf.io/mg7b4/ [34]: https://osf.io/ty8qv/ [35]: https://osf.io/bnygm/ [36]: https://osf.io/cs683/ [37]: https://osf.io/65u8a/ [38]: https://osf.io/854m2/ [39]: https://osf.io/3t2j4/ [40]: https://osf.io/kfu47/ [41]: https://osf.io/dar7t/ [42]: https://osf.io/xp6jv/ [43]: https://osf.io/rn9z6/ [44]: https://osf.io/n837k/ [45]: https://osf.io/pbgy4/ [46]: https://osf.io/4c6za/ [47]: https://osf.io/eksv3/ [48]: https://osf.io/y2tbg/ [49]: https://osf.io/z6se4/ [50]: https://osf.io/anwqu/ [51]: https://osf.io/9zxh7/ [52]: https://osf.io/awxvd/ [53]: https://osf.io/vcbmu/ [54]: https://osf.io/gjxh6/ [55]: https://osf.io/zuamw/ [56]: https://osf.io/7kmzs/ [57]: https://osf.io/bsg9w/ [58]: https://osf.io/a3gdj/ [59]: https://osf.io/ykmza/ [60]: https://osf.io/uqn6k/ [61]: https://osf.io/w2p45/ [62]: https://osf.io/9nbr3/ [63]: https://osf.io/pn5g4/ [64]: https://osf.io/a3wn5/ [65]: https://osf.io/k4wz7/ [66]: https://osf.io/tkrvq/ [67]: https://osf.io/bqfcg/ [68]: https://osf.io/62m8q/ [69]: https://osf.io/9e6t5/ [70]: https://osf.io/69he8/ [71]: https://osf.io/dpbqk/ [72]: https://osf.io/2fhky/ [73]: https://osf.io/jx792/ [74]: https://osf.io/nmkb8/ [75]: https://osf.io/sz6kx/ [76]: https://osf.io/fhpju/ [77]: https://osf.io/9uf8v/ [78]: https://osf.io/xcpd3/ [79]: https://osf.io/gnfsc/ [80]: https://osf.io/msr2w/
