# Table 3 Sample Calculations of Maximal Standardized Parent Participation Profiles and Parent Engagement Intensity with Examples of Participation

Possible Activities
(Possible Frequencies)
Maximal PPP
Standardized PPPa
Maximal PEI
Standardized PEIb
School A
control cohort
Parent Surveys (3)
Example – parent completed
2 surveys
1
1/1 = 100%
6
(2 + 2)/6 = 66%
School B
control cohort
Parent Surveys (3)
Example – parent completed 4
About Eating lessons and 1 survey
2
2/2 = 100%
12
(4 + 2)/12 = 50%
School C
FFF cohort
About Eating lessons (6) Recipes (5)
Parent Surveys (3)
Parent Diet Assessment (3)
Youth Diet Assessment (3)
Example – parent completed 3
surveys, 3 youth diet assessments (2 recalls each), and 1 About Eating lesson
5
3/5 = 60%
30
(2 + 2 + 2 + 2 + 2 + 2 + 1)/30 = 43.3%
D – FFF year Family Nights (2); Action Pack (10)
Recipes (5); About Eating lessons (6)
Parent Surveys (3); Accelerometer (3)
Parent Diet Assessment (3)
Child Diet Assessment (3)
Example – Parent completed 5 action packs,
4 About Eating lessons, 2 parent surveys,
2 parent diet assessment (2 recalls each) and 2 youth diet assessments (3 recalls each)
8
5/8 = 62.5%
48
(2 + 4 + 2 + 2 + 2 + 2 + 2 + 2)/48 = 37.5%
1. PPP Parent Participation Profile, PEI Parent Engagement Intensity
2. a Count activity types to calculate PPP; Divide parent PPP by maximal PPP possible to calculate standardized PPP
3. b Multiply Frequency (in parentheses) by the Intensity Factor to calculate PEI; Divide PEI by maximal PEI possible to calculate standardized PEI
4. Frequency: 1 to 3 action packs = 1 point; 4–6 action packs = 2 points; 7–10 action packs = 3 points; 1 recipe =1 point; 2 to 3 recipes =2 points; 4 to 5 recipes =3 points; At each of 3 time points 1 diet recall =1 point, 2 or 3 diet recalls =2 points
5. Intensity Factor: Family Nights 3; Action Packs 2; Recipe Preparation 2; About Eating 1; Parent Survey 2; Parent Diet Assessment 1; Youth Diet Assessment 1; Accelerometry 2
