	Responsibility for the problem		The role of humans and specific cities or countries in driving the problem of climate change
	Manufactured problem (S)		Denial of climate change as a real problem, belief that it is manufactured for profits or political gain, or a perception that climate change is being blown out of proportion
Risk & Awareness
	Lack of public knowledge		A deficit of public knowledge on climate change or the risks in general.

	Change is constant (S)		Belief that climate change is natural or normal, or part of a cycle that is constantly changing
	Skepticism or denial of the risk (S)		Belief that climate change is not a risk personally or more generally, that the problem is not worsening
	Temporal risk		When people believe the risk of climate change will be realized
	Geographic risk
		Globally	The risk of climate change for people around the world, or specifically in other countries
		Locally	The risk of climate change for the specific area or city that participants live in
		Personally	The risk of climate change to participants personally
Solutions and politics
	Adaptation		The necessity and measures of adapting to climate change.
	Energy transition		The necessity and measures of transitioning away from fossil fuel energy.
	Individual and collective action		The role of individual and/or collective action
	Disbelief or skepticism of solutions (S)		Skepticism or doubt around some of the climate change solutions (e.g. electric cars)
	Climate science		Scientific consensus on climate change
	Lack of scientific knowledge (S)		Belief that there is a lack of climate or weather data, and other scientific information on climate change
	Government, politics		The political dimensions of climate change
Perceptions of Lyme Disease
Level 1 code	Level 2 code	Level 3 code	Definition
Lack of Knowledge
	Public		A deficit of knowledge on Lyme disease amongst the public, such as lack of public education on symptoms, consequences, and causes.
	Medical		A deficit of knowledge on Lyme Disease amongst doctors and medical professionals, such as misinformation or lack of capacity around diagnosis.
Causes of Spread
	Climate Change		Blacklegged ticks spreading and migrating because of specifically climate change.
	Habitat change		Blacklegged ticks migrating or moving because of loss of habitat cause by humans (e.g. deforestation, encroachment)
	Migration		Blacklegged ticks moving around on animals or otherwise naturally migrating to new areas
	Weather		Tick spreading is due to weather or humidity.
	Spread is not climate change related (LS)		The cause of ticks spreading is specifically not climate change related
	Natural spread, cycles in ticks (LS)		Spread of ticks to new areas is natural or part of a pattern or cycle in their populations
Illness Representation
	Causes		The source of Lyme Disease, such as the specific ticks that carry the disease
	Symptoms		The physical (e.g. bullseye rashes) and mental (e.g. depression) impacts of Lyme Disease.
	Definition		Participants feelings about ticks (e.g. disgust) or feelings about Lyme Disease (e.g. scared).
	Consequences		Outcomes of having Lyme Disease (e.g. loss of job, needing to travel to get treatment, etc.)
	Trajectory		The course of living with Lyme Disease (e.g. curable, chronic)
	Treatment & Prevention
		Preventative Behaviour	What can be or has been done to avoid getting bitten by ticks and contracting Lyme Disease (e.g. applying bug spray)
		Treatment	The process, location, cost, etc. of medical treatment to cure or lessen Lyme disease symptoms
Risk and Awareness
	Temporal and geographic dimensions of risk		Who could get Lyme Disease, where they could get it (e.g. walking their dog, in their grass, etc.) and when they could get it (e.g. seasonality, etc.)
	Increasing public awareness		Hearing about Lyme Disease more, increasing discussion of the disease in the public sphere
	Source of risk information		Sources of information about Lyme Disease (e.g. radio, news, relationships)
		Media coverage	Coverage of Lyme Disease information through media specifically
	Diagnosis or risk increasing (LS)		Skepticism amongst participants about whether the risk of Lyme Disease is increasing or if increasing number of reported cases is just a result of doctors becoming more aware of Lyme Disease and how to diagnose it.
	Risk is not new (LS)		Ticks are not new, and have been around for a long time.
	Absence of risk (LS)		Lack of concern about Lyme Disease, belief that the disease risk is not significant
