Percentage of Dyads (Participant and Caregiver or Parent) Reporting no Difference or Easier to Use for New Genotropin Mark VII Injection Pen Compared to Pre-study Experience With the Genotropin Pen® [ Time Frame: 2 months ]
Ease of use measured using the Injection Pen Assessment Questionnaire (IPAQ) patient-reported outcome (PRO) tool (based on 13 unique characteristics of injection pens). Section I measures ease of use of Genotropin® (very easy, somewhat easy, neither easy nor difficult, somewhat difficult, or very difficult). Section II measures ease of use of new Genotropin Mark VII Pen in comparison to pre-study experience with Genotropin® Pen (Genotropin® pen easier to use, new injection pen easier to use, or no difference) and preference (prefer Genotropin® Pen, prefer new injection pen, or no preference).
Proportion of dyads that reported the experience using the genotropin pen as no different or easier to use than the pre-study pen [ Time Frame: 2 months ]
