drug

did the patient take anti-depressant drugs (No or Yes).

length

the length of the current episode of depression, a factor with levels <6m (less than six months) and >6m (more than six months).

treatment

treatment group, a factor with levels TAU (treatment as usual) and BtheB (Beat the Blues)

bdi.pre

Beck Depression Inventory II before treatment.

bdi.2m

Beck Depression Inventory II after two months.

bdi.3m

Beck Depression Inventory II after one month follow-up.

bdi.5m

Details

Longitudinal data from a clinical trial of an interactive, multimedia program known as "Beat the Blues" designed to deliver cognitive behavioural therapy to depressed patients via a computer terminal. Patients with depression recruited in primary care were randomised to either the Beating the Blues program, or to "Treatment as Usual (TAU)".

Note that the data are stored in the wide form, i.e., repeated measurments are represented by additional columns in the data frame.

Examples

  data("BtheB", package = "HSAUR2")
  layout(matrix(1:2, nrow = 1))   
  ylim <- range(BtheB[,grep("bdi", names(BtheB))], na.rm = TRUE)
  boxplot(subset(BtheB, treatment == "TAU")[,grep("bdi", names(BtheB))],
          main = "Treated as usual", ylab = "BDI", 
          xlab = "Time (in months)", names = c(0, 2, 3, 5, 8), ylim = ylim)
  boxplot(subset(BtheB, treatment == "BtheB")[,grep("bdi", names(BtheB))], 
          main = "Beat the Blues", ylab = "BDI", xlab = "Time (in months)",
          names = c(0, 2, 3, 5, 8), ylim = ylim)
