5. Variable-Centered Approach Previous Research Previous Research Specific focus on one activity context Specific focus on one activity context Sum score of extracurricular participation Sum score of extracurricular participation Pattern-Centered Approach  Multiple Activity Settings  Both Constructive and Passive Activities Cooper et al., (1999) Cooper et al., (1999) Shanahan & Flaherty (2001) Shanahan & Flaherty (2001) Bartko and Eccles (2003) Bartko and Eccles (2003)

6. Research Hypotheses  Youth in the Sports Activity patterns will report: Higher academic achievement Higher academic achievement Higher rates of alcohol use Higher rates of alcohol use  Differences between the Sport-Dominant Activity patterns Sports+Act(s) = highest academic achievement Sports+Act(s) = highest academic achievement Sports-only = highest alcohol use Sports-only = highest alcohol use  Continuity of Sports participation Basic Model: Sports, Low Engaged, Others Basic Model: Sports, Low Engaged, Others Multi-Sport Model: Sport-only, Sport+Act(s), Low Engaged, Others Multi-Sport Model: Sport-only, Sport+Act(s), Low Engaged, Others

Sameroff) A community-based longitudinal study A community-based longitudinal study 7 th, 9 th, and 11 th grades, 1 and 3 yrs post H.S. 7 th, 9 th, and 11 th grades, 1 and 3 yrs post H.S. 1,482 adolescents and their families 1,482 adolescents and their families 49% female 49% female 61% African American, 35% White 61% African American, 35% White Pretax family income in 1990: Pretax family income in 1990: Mean: 42,500-52,500 / Range: 5, 000-75,000 Mean: 42,500-52,500 / Range: 5, 000-75,000 Income normatively distributed among both African Americans and Whites.

9. Measures Youth Activities Constructive Activities Constructive Activities Sports, School-related, Community, Volunteer and Religious activities. Sports, School-related, Community, Volunteer and Religious activities. Reading, Homework, Work, Chores and playing a Musical Instrument. Reading, Homework, Work, Chores and playing a Musical Instrument.  Passive Activities  Hanging out with Friends and Watching Television Activities were measured on a scale of 1 thru 5 (1=little to no involvement in the activity 5=participate daily)

10. Measures continued… Academic Achievement  Grade Point Averages (7 th, 9 th,and 11 th Grades)  How far youth is expected to go in school  (1=LE 11thgrade; 6=Bachelor’s Degree; 8=MD, Law, Ph.D)  Actual Educational Attainment (1-3years post-H.S.)  (1=Attrition; 2=Dropout of H.S.; 3=H.S. Diploma/No College; 4=H.S. Diploma and College) Alcohol Use  How often youth had an alcoholic beverage(s) in the past 6 months  (0=none; 1=rarely; 2=2-3times a month; 3=GE 1/week)
