1. Participants: 65 Pregnant Adolescents in Teen Parent Programs Means: age: 16.12, GPA: 2.04, age/grade lag:.17, Grade: 10.8, FOB/MOB age difference: 3.17 year Percentage: AA (13%), Hispanic (42%), Caucasian (45%). Refusal rate: 2% Attrition: 6% (fetal demise, diagnosis of CA) 7 Sites: Relationship of demographics to school attendance: site, ethnicity, SES, age, grade, GPA P values:.13 -.95 Was I happy?

3. Questionnaire Reliability  72 items on questionnaire  Likert scale: evenly spaced  Response set bias: Some positive, some negative; Took 15-20 minutes to complete  Test-Retest: Okay  4 practice questions related to eating at McDonald’s  Paper and pencil  6 questions on a page  5 th grade reading level

4. Internal Validity: Controlling It!  History? Took place over 9 months  Maturation?  Selection? convenience sample. Refusal rate: 2%; demographics the same among sites.  Mortality: 6% attrition for unforeseen reasons

5. Statistical tests: Were the right ones used?  Demographics: 7 groups: ANOVA used.. not 42 T-Tests  Linear Regression: Not single order correlations  DV: school attendance: interval data: 1-21 days.  Variables entered into the computer in a step-wise manner based on the TPB: 1 st : Demographics then TPB concepts

6. DV: C = School attendance: IV: A= Attitude: r = AC + ABC R2= AC beta = AC IV: B= Social Norm r = BC+ABC beta= BC

8. Did the theory (model) work? How do you know? Why are the R2 and Adjusted R2 different (think sample size!) R2Adjusted R2FP (.05).140.0933.007.023

9. Does the TBP help us understand school attendance? IVs: Demographics: Did not predict school attendance: P =.28 -.62 IVs: Attitude + Social Norm + Perceived Control + Intention Predicted: DV: School Attendance Why is this a helpful thing to know?
