1 VERITAS dataset description

Unlike the Eligibility or Health questionnaires, which can mostly be encoded as a flat table, the VERITAS questionnaire implicitly records a series of entities and their relationships:

  • Places: list of geocoded locations visited by participants, along with the following characteristics: category, name, visit frequency, transportation mode
  • Social contacts: people and/or groups frequented by participants
  • Relationships: between social contacts (who knows who / who belongs to which group) as well as between locations and social contacts (places visited along with whom)

The diagram below illustrates the various entities collected throught the VERITAS questionnaire:

2 Basic descriptive statistics

2.1 Section 1: Residence and Neighbourhood

2.1.1 Now, let’s start with your home. What is your address?

home_location <- locations[locations$location_category == 1, ]

## version ggmap
skt_aoi <- st_bbox(filter(home_location, interact_id != "302386742"))
names(skt_aoi) <- c("left", "bottom", "right", "top")
skt_aoi[["left"]] <- skt_aoi[["left"]] - .05
skt_aoi[["right"]] <- skt_aoi[["right"]] + .05
skt_aoi[["top"]] <- skt_aoi[["top"]] + .01
skt_aoi[["bottom"]] <- skt_aoi[["bottom"]] - .01

bm <- get_stadiamap(skt_aoi, zoom = 11, maptype = "stamen_toner_lite") %>%
  ggmap(extent = "device")
bm + geom_sf(data = st_jitter(home_location, .008), inherit.aes = FALSE, color = "blue", size = 1.8, alpha = .3) # see https://github.com/r-spatial/sf/issues/336

NB: Home locations have been randomly shifted from their original position to protect privacy.

# Number of participants by municipalites

2.1.2 When did you move to your current address?

# N of addresses by date of move
year_of_move <- veritas_main[c("interact_id", "home_move_date")]
year_of_move$home_move_date <- year(ymd(year_of_move$home_move_date))

2.1.3 If you were asked to draw the boundaries of your neighbourhood, what would they be?

prn <- poly_geom[poly_geom$area_type == "neighborhood", ]

## version ggmap
bm + geom_sf(data = prn, inherit.aes = FALSE, fill = alpha("blue", 0.05), color = alpha("blue", 0.3))
