Figure 1. Parental responses to items probing factors that may influence decision to enroll a child in type 1 diabetes clinical trials (T1DCTs).. From: Factors That Influence Parental Attitudes toward Enrollment in Type 1 Diabetes Trials.

Parents were asked: “There are lots of things that might affect a parent/guardian's decision to enroll a child in clinical trials. How much would the following influence your decision to enroll a child in a type 1 diabetes clinical trial?” Shapes correspond to endorsed degree of influence on a five-point Likert scale: black square  =  not at all, black circle  =  a little, white triangle  =  some, white circle  =  a great deal, white square  =  completely. The X-axis represents proportion of parents endorsing a specific level of influence.

Figure 2. Parental responses to items probing comfort with various clinical trial protocols.. From: Factors That Influence Parental Attitudes toward Enrollment in Type 1 Diabetes Trials.

Parents were asked: “We would like to know more about how specific tasks that may be part of a Type 1 diabetes clinical trial may influence your decision to enroll your child. How comfortable would you feel if your child were asked to do the following?” Shapes correspond to self-described comfort score on a five-point Likert scale: black square  =  not at all, black circle  =  a little, white triangle  =  some, white circle  =  a great deal, white square  =  completely. The X-axis represents proportion of parents endorsing a specific comfort score. “All Respondents” indicates protocol-specific comfort breakdown for all parents; “Willing to Enroll” indicates protocol-specific comfort breakdown for parents who endorsed they were “completely” or “a great deal” willing to enroll a child with diabetes; “Not Willing to Enroll” indicates protocol-specific comfort breakdown for parents who endorsed they were “not at all” or “a little” willing to enroll a child with diabetes. Breakdown for reponses depending on willingness to enroll an unaffected child are not shown as results are similar. Green box highlights tasks with which >60% of all parents were “a great deal” or “completely” comfortable. The purple box highlights tasks with which <30% of all parents were “a great deal” or “completely” comfortable. Comfort with all protocols surveyed had a statistically significant positive correlation with both willingness to enroll a child with diabetes and a non-affected child (r = 0.23–0.6). This effect can be appreciated above by the larger green and much smaller purple box among parents who reported willingness to enroll their children in T1DCTs.
