1Development and Initial Validation of the Student
Strengths Inventory A Measure of Non-cognitive
Variables that Impact Student Performance and
Retention

- Drake University
2Graduation and Retention Rates
- 34 - Four-year graduation rate at two-year
institutions - (Swail, 2004)
- 53 - Six-year graduation rate at four-year
institutions - (Carey, 2004)
- First to second year retention rates
- (ACT, 2009)
Selective 82.2
Traditional 71.5
Open 65.1
Two-Year 53.9
3Student Success Models
- Primary focus on cognitive factors (ACT, HSGPA)
- Pre-enrollment situational (e.g., SES)
- Post-enrollment situational (e.g., Housing)
- Non-cognitive/motivational (e.g., engagement)
- 10 non-cognitive variables that are strong
predictors of student outcomes - Different predictors for retention vs.
performance - Approximately 4 6 of these offer significant
incremental validity over standardized tests and
HS GPA - Robbins et al., (2004)
4SSI Development
- Rational and factor analytic methods
- Homogeneous and objective measures of six factors
- Initial pool of 243 items developed by team of 6
researchers - Reduced to 81 items through consensus
- 10 14 items for each construct
- 1 6 (strongly disagree strongly agree)
- Academic engagement
- Academic self-efficacy
- Campus engagement
- Social comfort
- Resiliency
- Educational commitment
5Methods
- Administered to N 760 first-year college
students at two large western universities (one
urban commuter and one rural residential) - 45 men and 55 women
- Caucasian (65), Mexican/Chicano (9),
multiracial (5), Asian American (5), American
Indian (5), Puerto Rican/Cuban/Other (3.4) and
African American (2.6) - Over 8,000 students included in predictive
modeling analysis
6Analysis
- Factor Analysis
- Principal axis factoring with oblique rotation
- 6 factor structure converged in 11 iterations
- Accounted for 45 of variance among items
- Reliability
- Internal Consistency
- Construct Validity
- Correlation with Student Readiness Inventory
- Predictive Validity
- Prediction of retention and first semester GPA

Student
Strengths Inventory Scales and Sample Items
Scale Definition Sample Item
Academic Engagement The value an individual places on academics and attentiveness to school work. I turn my homework in on time.
Academic Self-Efficacy An individuals confidence in his or her ability to achieve academically and succeed in college. I will excel in my chosen major.
Educational Commitment An individuals dedication to college and the value placed upon a college degree. I see value in completing a college education.
Resiliency An individuals approach to challenging situations and stressful events. I manage stress well.
Social Comfort An individuals comfort in social situations and ability to communicate with others. I am comfortable in groups.
Campus Engagement Involvement in campus activities and attachment to the college/university. Being active in extra-curricular activities in college is important to me.
