Pediatric Caregiver Version of the Shared Decision Making Process Scale: Validity and Reliability for ADHD Treatment Decisions.

OBJECTIVE: Shared decision making (SDM) is recommended for common pediatric conditions; however, there are limited data on measures of SDM in pediatrics. This study adapted the SDM Process scale and examined validity and reliability of the scale for attention-deficit/hyperactivity disorder (ADHD) treatment decisions. METHODS: Cross-sectional survey of caregivers (n = 498) of children (aged 5-13) diagnosed with ADHD, who had made a decision about ADHD medication in the last 2 years. Surveys included the adapted SDM Process scale (scores range 0-4, higher scores indicate more SDM), decisional conflict, decision regret, and decision involvement. Validity was assessed by testing hypothesized relationships between these constructs. A subset of participants was surveyed a week later to assess retest reliability. RESULTS: Pediatric Caregiver version of the SDM Process scale (M = 2.8, SD = 1.05) showed no evidence of floor or ceiling effects. The scale was found to be acceptable (<1% missing data) and reliable (intraclass correlation coefficient = 0.74). Scores demonstrated convergent validity, as they were higher for those without decisional conflict than those with decisional conflict (2.93 vs 2.46, P < .001, d = 0.46), and higher for caregivers who stated they made the decision with the provider than those who made the decision themselves (3.0 vs 2.7; P = .003). Higher scores were related to less regret (r = -0.15, P < .001), though the magnitude of the relationship was small. CONCLUSIONS: The adapted Pediatric Caregiver version of the SDM Process scale demonstrated acceptability, validity and reliability in the context of ADHD medication decisions made by caregivers of children 5-13. Scores indicate pediatricians generally involve caregivers in decision making about ADHD medication.
