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 = c(3, 3, 3, 4, 4, 4),
  partA_cutoff = 4,
  verbose = TRUE
)

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; if TRUE, emits informational messages about column resolution and scoring progress via hm_inform().

Value

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

Note

Items are expected on a 0–4 scale (Never=0, Rarely=1, Sometimes=2, Often=3, Very Often=4). The default partA_thresholds follow the official WHO ASRS v1.1 guide: items 1–3 are positive at \(\geq 3\) (Often or Very Often) and items 4–6 at \(\geq 4\) (Very Often only).
