The Student Satisfaction Inventory measures students' satisfaction with
a wide range of college experiences.Principles of consumer theory serve
as the basis for the inventory's construction. Therefore, students are
viewed as consumers who have a choice about whether to invest in education
and where to enroll. In addition, students are seen as individuals who
have definite expectations about what they want from their campus experience.
From this perspective, satisfaction with college occurs when an expectation
is met or exceeded by an institution.
Students rate each item in the inventory by the importance of the specific expecation as well as their satisfaction with how well that expectation is being met. A performance gap is then determined by the difference in the importance rating and satisfaction rating. Items with large perforamnce gaps indicate areas on campus where students perceive their expectations are not being met adequately.
Because the Student Satisfaction Inventory results in three different scores for each item, a significant amount of information is generated for institutional decision makers. Importance score ratings reflect how strongly students feel about the expectation (the higher the score, the more important it is to a student, hence the stronger the expecation). Satisfaction ratings show how satisfied students are that your institution has met the expectation (the higher the score, the more satisfied the student). Performance gap scores (importance rating minus satisfaction rating) show how well you are meeting the expectation overall. A large performance gap score for an item (e.g., 1.5) indicates that the institution is not meeting students' expectations, whereas a small or zero gap score (e.g., .50) indicates that an institution is meeting students' expectations, and a negative gap score (e.g., -.25) indicates that an institution is exceeding students' expectations. Please note that the above performance gap references are examples. What is defined as a large and small performance gap may vary by institution.
In addition to the information provided by the three measurements for each item, inventory composite scales offer a "global" perspective of your students' responses. The scales provide a good overview of your institution's strengths and areas in need of improvement.
The Items
The Student Satisfaction Inventory collects student feedback on over 100
items. Included are:
The Scales
For 4-year colleges and universities, 73 items of expectation and 6
items that assess the institution's commitment to specific student populations
are analyzed statistically and conceptually to provide the following
12 composite scales:
Reliability and Validity
The Student Satisfaction Inventory is a very reliable instrument. Both
the two-year and four-year versions of the SSI show exceptionally high
internal reliability. Cronbach's coefficient alpha is .97 for the set
of importance scores and is .98 for the set of satisfaction scores. It
also demonstrates good score reliability over time; the three-week, rest-retest
reliability coefficient is .85 for importance scores and .84 for satisfaction
scores.
There is also evidence to support the validity of the Student Satisfaction Inventory. Convergent validity was assessed by correlating satisfaction scores from the SSI with satisfaction scores from the College Student Satisfaction Questionnaire (CSSQ), another statistically reliable satisfaction instrument. The Pearson correlation between these two instruments (r=.71; p<.00001) is high enough to indicate that the SSI's satisfaction scores measure the same satisfaction construct as the CSSQ's scores, and yet the correlation is low enough to indicate that there are distinct differences between the two instruments.
