A 2-stage SMART data of children with ADHD

Description

We provide a two-stage sequential multiple assignment randomized trial (SMART) data of 150 children with ADHD mimicking a real world study. At the first stage, children were randomized to treatment of low-intensity behavioral modification (BMOD) or low-intensity methamphetamine (MED) with equal probability. At second stage, children were randomized to treatment of low-intensity BMOD + low-intensity MED, or high-intensity with equal probability. The primary outcome of study was children's school performance score ranging from 1 to 5 assessed at the end of the study for all participants

Usage

smart

Format

A data frame with 11 columns:

id

(factor) IDs of the 150 children.

o11

(factor) Baseline covariate encoded as 0/1: diagnosed with ODD (oppositional defiant disorder) before the first-stage intervention.

o12

(numeric) Baseline covariate: ADHD score at the end of the previous school year (ranging from 0 to 3, larger values for fewer ADHD symptoms).

o13

(factor) Baseline covariate encoded as 0/1: receiving medication during the previous school year.

o14

(factor) Baseline covariate encoded as 0/1: race - white (coded 1) versus nonwhite (coded 0).

a1

(factor) First-stage intervention encoded as -1/1: -1 for low-intensity methamphetamine (MEDS), 1 for low-intensity behavioral modification (BMOD).

r

(factor) First-stage response indicator encoded as 0/1

o21

(factor) Intermediate outcome: number of months until non-response (maximum: 8 months, NA for responders).

o22

(factor) Intermediate outcome encoded as 0/1: adherence to the first-stage intervention, 1 for high adherence.

a2

(factor) Second-stage intervention encoded as -1/1: -1 for low-intensity BMOD + MEDS, 1 for high-intensity BMOD.

y

(factor) Primary outcome (continuous): school performance at the end of the school year (ranging from 1 to 5, higher values reflect better performance)
