compute_ph_y_bp__sys_nm: Compute "Blood Pressure [Youth] (Systolic): Number missing"

In ABCDscores: Summary Scores of the Adolescent Brain Cognitive Development (ABCD) Study

Compute "Blood Pressure [Youth] (Systolic): Number missing"

Description

Computes the summary score ph_y_bp__sys_nm Blood Pressure [Youth] (Systolic): Number missing

• Summarized variables:

  • ph_y_bp__sys__r01_001

  • ph_y_bp__sys__r01_002

  • ph_y_bp__sys__r01_003

  • ph_y_bp__sys__r02_001

  • ph_y_bp__sys__r02_002

  • ph_y_bp__sys__r03_001

  • ph_y_bp__sys__r03_002

• Excluded values: none

Calculation

There are at most 3 possible rounds of measurements, and the calculation is as follows:

• if round 3 is available, use it, otherwise use round 2, otherwise use round 1

• for round 3 and 2, there are at most 2 measurements

• for round 1, there are at most 3 measurements:

  • participants with 3 measurements, and 0 missing, nm = 0

  • participants with 2 measurements, and 1 missing, nm = 1 - 1 = 0

  • participants with 1 measurement, and 2 missing, nm = 2 - 1 = 1

  • participants with 0 measurements, and 3 missing, nm = 3 - 1 = 2

Usage

compute_ph_y_bp__sys_nm(data, name = "ph_y_bp__sys_nm", combine = TRUE)

Arguments

data	tbl, Dataframe containing the columns to be summarized.
name	character, Name of the new column to be created. Default is the name in description, but users can change it.
combine	logical, If TRUE, the summary score will be appended to the input data frame. If FALSE, the summary score will be returned as a separate data frame.

Value

tbl. The input data frame with the summary score appended as a new column.
