Compute "Prodromal Psychosis Scale [Youth] (Persistent Distress Score)"

Source: R/scores_mh.R
compute_mh_y_pps__dist__pers_score.Rd

Computes the summary score mh_y_pps__dist__pers_score Prodromal Psychosis Scale [Youth] (Persistent Distress Score)

For the last 3 consecutive waves (this wave, prior annual wave, and the wave before that), if 2 or more waves have a mh_y_pps__dist__curr_score of "1", then score is "1", else "0"; if more than 1 NA values in the last 3 waves, then score is NA.

The persistent flag is derived from a padded annual timeline per participant. Missing annual visits between observed sessions are treated as NA, so each observed session evaluates the current wave plus the two immediately preceding annual slots, even if data were not collected for one of those visits. The special case where both ses-00A and ses-01A meet the threshold (1) is also treated as persistent at ses-01A.

  • Summarized variables:

    • mh_y_pps__dist__curr_score (intermediate score)

  • Excluded values: none

  • Validation criterion: none

Usage

compute_mh_y_pps__dist__pers_score(
  data,
  name = "mh_y_pps__dist__pers_score",
  combine = TRUE
)

Arguments
