VERY LITTLE IS KNOWN ABOUT THE COLLEGE
EXPERIENCES OF STUDENTS WITH ADHD/LD
LD/ADHD College Students
 May have increased rates of academic probation
 (Heiligenstein et al., 1999)
 May have lower GPAs-nearly 1 .0 lower
 ( Blasé
et al., 2009; Frazier et al., 2007)
 May have higher graduation rates (and persistence rates)
 (Canto et al., 2005;Huber, 2009; Vogel & Adelman 1992)
 May have lower overall retention & graduation rates: 11% -50%
lower
 Horn et al., 1999; Greg, 2009; Greenbaum et al., 1995;Lee et al. (2008);
Murray et al., 2000)
 May have the same graduation rates by may take longer to
graduate
 (Vogel & Adelman 1990, 1992; Jorgeson et al., 2003, Wessel et al., )

RESEARCH QUESTIONS
 Research Question 1 : Do students in the ADHD/LD Sample have
different enrollment patterns than students in the Random
Sample
 Research Question 2: Do the grade point averages of the
students in the ADHD/LD sample differ from students in the
Random Sample?
 Research Question 3: Are there differences in the graduation
rates between students in the ADHD/LD sample and students in
the Random Sample?
 Research Question 4: Within the ADHD/LD Sample does
diagnosis of ADHD, LD or both ADHD/LD impact graduation rate?
 Research Question 5: Do graduation rates and GPAs of students
with ADHD/LD differ based on the frequency of sessions with a
Learning Specialist?
STATISTICAL ANALYSES
 All descriptive and comparative analyses were performed
using StataIC 12 (StataCorp, 2011).
 Descriptive statistics, including measures of central tendency,
cross-tabulations, and chi-squares were used to compare
means and characterize the sample with respect to student
demographics, high school, and academic success variables.
 Linear regression, logistic regression, and multi -nomial
logistic regression models were employed to examine the
relationships among service use, student characteristics,
diagnosis, and academic success

USE OF SERVICES
ADHD/LD SAMPLE
ADHD/LD SAMPLE: USE OF SERVICES
Numbers of sessions range from 1-94, (M=7,
SD=10)
 76% (n=1,115/1461) of all students cleared for
services return for at least one session.
 Males (75%, n=613) and females (77%, n=502)
return for services at about the same rate.
ADHD/LD: USE OF SERVICES
SAT
 Students who return for services (n=858) are
statistically more likely to have higher SATM & SAT V
scores (by 20 points; p<.01) than those who do not
return (n=277) (ttest).
 Amount of service use: students with higher GPAs
had more service contacts with learning specialists
(b = 1.76, p < .027) [Richman, 2013].
 Students who used services two or more times were
twice as likely to be dually diagnosed with ADHD/LD
(exp(β)=.52, p < .002)[Richman,2013].

LIMITATIONS
 Findings not generalizable to other settings
 Many variables were not included in our data analysis model
(e.g. SES, self-determination, age of diagnosis, resiliency,
accommodation use etc.)
 Data on sessions is limited due to missing data (30%) and
some may not be accurate
 Students in the ADHD/LD group self selected voluntarily
 May be others in the RS given research on low rate of disclosure in
college students with disabilities
 If so, the differences between groups many be even greater
SUMMARY
When compared to their non -disabled peers, college students with
ADHD/LD :
 Are an at-risk population and may not be graduate at the same
rate as their non-disabled peers.
 Are at even greater risk than other at -risk populations
 Are significantly more likely to experience unusual enrollment
patterns than their peers without ADHD/LD
 Are significantly less likely to graduate
 Take longer to graduate
 Have lower GPAs
 Students attending more sessions showed trends (not
significant) toward higher graduation rates;
 Students attending more sessions had significantly higher GPAs
(Richman, 2013)
IMPLICATIONS
 Additional studies are needed in dif ferent settings to see if
findings are consistent and to determine what factors
influence student success
 Need to identify and implement evidenced based practices at
the high school and college level
 Need to disseminate “at -risk” status for transitioning teens
to:
 Parents and teens
 College administrators setting policy and developing programming
for at-risk groups on campuses
 Need creative programming strategies to attract teens reluctant
to access services
