Overview
Brief Summary
This study will examine the feasibility and acceptability of a family-oriented augmentation of the Diabetes Prevention Program lifestyle intervention (DPP), called the Family DPP. It will also preliminarily examine adult and child health and health behavior outcomes. The DPP is a 12-month, group-based lifestyle intervention for adults at high-risk for type 2 diabetes, in which adult participants learn skills and strategies to achieve the program's goals of 5% weight loss and 150 minutes/week of moderate-vigorous physical activity. The Family DPP will consist of all elements of the evidence-based DPP, along with augmentations including additional child-focused sessions in which adult participants will learn about principles and strategies for promoting healthy lifestyle behaviors in children, ages 5 through 12 years. Children may participate in certain child-focused sessions, too. The non-randomized pilot feasibility study will consists of 2 arms/groups: 1) the concurrent "control" group, consisting of adults who are enrolled in the DPP; and 2) the "intervention" arm, in which the adult participants will engage in the Family DPP (and children may participate in certain aspects of the Family DPP focused on children). The study will recruit 10-15 adult-child dyads, for the "intervention" groups, and 10-15 adults for the concurrent control group. In addition to data collected from adult participants as a routine part of the DPP, the study will examine additional adult health behaviors and health outcomes and child health outcomes (change in body mass index z-score) and health behaviors at baseline, 6 months and 12 months (program end) among participants in the "intervention" group.

Outcomes
Primary Outcomes
Adult Participant Attendance in Program as Assessed by Total Number of Required Program Sessions Attended, Core
Time Frame: 6 months
The average total number of required core period program sessions attended by the adult participant (inclusive of make-up sessions) including all DPP (and, if in Family DPP, additional Family DPP sessions); for Family DPP adult participants this will also be examined for the subset of DPP sessions and additional Family DPP sessions.
Adult Participant Attendance in Program as Assessed by Total Number of Program Sessions Attended, Full Program
Time Frame: 12 months
The average total number of all required sessions attended by the adult participant (inclusive of make-up sessions); for Family DPP adult participants this will also be examined for the subset of DPP sessions only, and additional required Family DPP sessions only (of which there were 10), and didactic/required child-focused sessions only (of which there were 8).
Adult Participant Attendance in Program as Assessed by Percentage of Program Sessions Attended, Core
Time Frame: 6 months
The average percentage of required core period program sessions attended by the adult participant (inclusive of make-up sessions) in each arm (denomiator of 18 for DPP, and 20 for Family DPP); for Family DPP adult participants this will also be examined for the subset of required DPP sessions only (denominator is 18) and additional Family DPP sessions only (of which there were 2).
Adult Participant Attendance in Program as Assessed by Percentage of Program Sessions Attended, Full Program
Time Frame: 12 months
The percentage of all required program sessions attended by the adult participant (inclusive of make-up sessions); for Family DPP adult participants this will also be examined for the subset of DPP sessions only, all additional Family DPP sessions only (of which there were 10), and child-focused DPP sessions only (of which there were 8).
Feasibility of Measurement of Child-related Outcomes as Assessed by the Percentage of Total Child Participants for Whom Data Are Collected
Time Frame: 12 months
The percentage of total enrolled child participants (in the Family DPP intervention arm) for whom BMI data and child-health behavior data are collected will be examined for the 12 month data point.
Child Participant Attendance in Family Diabetes Prevention Program
Time Frame: 12 months
The percentage of required child-focused sessions (N=8) attended by the child participant will be examined for child participants in the Family DPP arm only.
Satisfaction With Family Diabetes Prevention Program as Assessed by Study Team Designed Questionnaire
Time Frame: 12 months (end of intervention)
Mean Likert-scale score (for most items, Likert scale on a range of 1 to 4; from strongly disagree (1) to strongly agree (4)), exploring satisfaction with Family DPP content and structure). Mean of participant choice is reported.
Intervention Fidelity as Assessed by a Fidelity Checklist
Time Frame: Up to 12 months
Using an adapted DPP fidelity checklist, this will examine fidelity of delivery of Family DPP specific sessions; percentage of content delivered by coach during session is reported.
Total Cost of Program Delivery
Time Frame: 12 months (end of intervention)
Cost of program delivery (including staffing, materials, wrap-around support) per participant (or for FDPP, per dyad). Calculated separately for DPP and Family DPP (intervention) arm. Total delivery cost of DPP incurred by the delivering center was used for DPP cost/participant- this is calculated as a total cost for a set number of cohorts/participants, divided by number of participants. There is a single value (no variation) for each category of cost that was used to calculate this number, and thus no measure of precision or dispersion can be calculated due to nature of calculating a total cost. For FDPP dyads, additional costs related to FDPP intervention and delivery were included in this calculation.
Recruitment Rate as Assessed by the Rate of Enrollment Per Week
Time Frame: During recruitment period up to 22 weeks
Recruitment rate is calculated as the number of eligible participants (adult controls or adult-child dyad intervention arm) consenting and completing enrollment and participating in the trial, divided by period of recruitment (in weeks). This value is calculated separately for intervention arm and concurrent control group. The measure is calculated as # of participants recruited (total)/total number of weeks of recruitment. (For intervention arm, 12 adult-child dyads/22 weeks; for control arm adults: 10 adults/9.5 weeks).
Survey Administration Feasibility as Assessed by Mean Time for Administration of Surveys to Participants
Time Frame: 12 months
Mean time (minutes) for administration of surveys to adult participant and child participant in the Family DPP (intervention) arm.
