Prevention of Paralytic Shellfish Poisoning in Subsistence Shellfish Harvest Communities of Southeast Alaska

The investigators will assess student learning with pre-unit and post-unit written evaluations that collect information on students' cultural and scientific knowledge using Likert scale questions. Likert-scale responses ranged from disagree (1) to agree (5). Here we report post education unit outcomes. We report pre education unit outcomes in baseline characteristics. Questions 10 and 13 of our survey reflect this outcome measure.

The investigators will assess changes in student self-reported behavioral history and student behavioral intentions with pre-unit and post-unit written evaluations that collect information on students' history to date of participating in subsistence shellfish harvest activities and students' behavioral intentions to participate in subsistence shellfish harvest activities and to check the SEATOR website, measured using Likert scale questions. Likert-scale responses ranged from disagree (1) to agree (5). Here we report post education unit outcomes. We report pre education unit outcomes in baseline characteristics. Questions 6, 7, 8, 15, and 16 reflect this outcome measure. Questions 8 and 16 are excluded from the pre-post program statistical tests as these questions are only relevant in the post-program survey.

The investigators will assess changes in student self-reported feelings about shellfish harvesting relevant to the Theory of Planned Behavior, including whether students think shellfish harvesting is enjoyable and rewarding, whether peers approve of shellfish harvesting and participate in shellfish harvesting, and whether students feel empowered to make shellfish harvesting decisions, with pre-unit and post-unit written evaluations that collect information on students' feelings about shellfish harvesting, measured using Likert scale questions. Likert-scale responses ranged from disagree (1) to agree (5). Here we report post education unit outcomes. We report pre education unit outcomes in baseline characteristics. Questions 1, 2, 3, 4, 5, 9, 10, 11, 12, 13, and 14 reflect this outcome measure. Questions 10 and 13 are used to assess both this outcome and primary outcome 1 and so are reported under both measures.

The investigators conducted interviews at the beginning and end of each semester's program (before and after all units). To analyze data, a codebook was generated using both inductive and deductive approaches. First, codes were identified based on major themes in the interview protocol and relevant to the TPB. Next, all transcripts were reviewed to identify further themes not captured in deductively developed codes. This grounded theory approach was important to identify new themes raised by participants. Data was coded and analyzed using Dedoose software. Here we report themes raised in post-program interviews. Participant quotations reflecting these themes can be found in the published paper from this study.

The investigators will follow up with participants one year after participation in the educational program to assess whether participants have had any behavior changes related to subsistence shellfish consumption, measured using Likert scale questions. Likert-scale responses ranged from disagree (1) to agree (5).
