Adult ADHD Self-Report Scale scoring

Usage

asrs_score(
  data,
  col_map = list(),
  na_action = c("keep", "omit", "error"),
  missing_prop_max = 0.2,
  impute = c("none", "mean"),
  prefix = "ASRS",
  partA_items = sprintf("asrs_%02d", 1:6),
  partA_thresholds = rep(2, 6),
  partA_cutoff = 4,
  verbose = FALSE
)

Arguments

data: Data frame containing questionnaire item columns.
col_map: Named list mapping canonical item IDs to column names; defaults assume items are already named.
na_action: How to handle rows with missing items: keep, omit, or error.
missing_prop_max: Maximum allowed proportion of missing items per row before the score is set to NA.
impute: Imputation strategy for missing items when under the threshold: none or mean (row-wise mean).
prefix: Prefix for output column names.
partA_items: Vector of Part A item IDs.
partA_thresholds: Numeric thresholds applied to Part A items.
partA_cutoff: Count threshold for Part A positivity.
verbose: Logical flag for verbose messaging (reserved).

Value

A tibble of score columns only: ASRS_total, ASRS_partA_count, ASRS_partA_positive. Input columns are not included.
