COURSE DESCRIPTION:
This course focuses on the development of knowledge and skill in measuring social,
psychological, environmental, and other factors related to intervention with individuals, families,
groups, and organizations.
COURSE OBJECTIVES (SUBJECT TO APPROVAL OF RELEVANT FACULTY COMMITTEES):
Upon completion of the course, students should be able to:
1. Describe the theoretical, conceptual, and methodological foundations of qualitative and
quantitative measurement;
2. Develop and test theory-based scales, starting from a theoretically and empirically
justified item pool;
3. Conduct cognitive testing of potential scale items with representatives of an appropriate
target audience and analyze the data;
4. Conduct exploratory factor analysis using one or more basic statistics programs to
identify and evaluate the factor structure of scales;
5. Conduct confirmatory factor analysis to further support the validity of scales, and
understand the implications of data characteristics on the choice of software and analysis
strategies
6. Evaluate the reliability and validity of quantitative indices and scales;
7. Apply principles of measurement to research that involves issues of difference arising
from culture, ethnicity, language, race, religion, sexual orientation, and other aspects of
human diversity.
EXPANDED DESCRIPTION:
Research is possible only to the extent that concepts can be measured. If we cannot measure
something, we cannot draw conclusions about how often it occurs, what conditions are
antecedent to it, what factors covary with it, and so on. In that regard, some concepts are easy to
measure. Age and education are often measured in years. Income is measured in dollars and
1
school performance is measured by GPA. Some concepts, however, are harder to measure.
―Practice wisdom,‖ for example, is widely acknowledged as a concept that discriminates more
successful social workers from less successful social workers. What is practice wisdom? How
do we conceptualize and measure it?
For this course, measurement will be defined broadly. It is the craft of systematically
describing something that exists. The course will focus on one qualitative scale development
step and then a sequence of quantitative steps can be used together to develop high quality
measures. Course activities are designed to build both knowledge and skill. Consequently,
students will be expected to engage in a variety of applied learning experiences.
The issues that we will address are at the heart of intervention research. How, for
example, do we measure child abuse, delinquency, client-worker relationships, skills, feelings,
attachment, and other important concepts in the profession? Most people would agree that these
exist, but they are constructs that are not easily operationalized.
The goal if the course is to strengthen your skills in a mixed methods process of
developing quantitative measures of concepts commonly used in social work research. The
course is designed as a seminar. Readings and discussion will focus on the theoretical and
conceptual foundations of quantitative measurement. Students will be expected to take a
leadership role in the course—bringing to class meetings knowledge from outside readings and
experiences, and asking and helping to answer questions related to course topics that further the
growth of all class participants.

TEACHING METHODS:
Teaching methods include lecture, discussion, computer labs, and group activities. Students are
expected to contribute actively to the learning climate of the classroom. Questions on course
topics and other issues in research and professional development are welcome.
ATTENDANCE AND CLASS ASSIGNMENTS:
Attendance. Students are expected to attend all class meetings, complete assigned and
independent readings, and contribute to the development of a positive learning environment in
the seminar. Students who miss 3 class meetings (excused and/or unexcused, and including
cumulative partial missed classes) will be required to take an Incomplete in the course and to
retake either the missed sessions or the entire course the following year before receiving a grade.
Course discussions and activities will be responsive to student interests. It is hoped that students
will share relevant knowledge and experience they already have related to course topics to enrich
the learning of other seminar participants. In addition, contributions based on independent
exploration of measurement topics beyond the stated course content are welcome. Attendance
and participation will be assessed weekly. Students who miss a class are fully responsible for
obtaining all missed information and materials from their classmates.
Graded Assignments:
One paper on your cognitive testing procedures and findings (Due Thursday, October 7)
One homework on EFA and reliability
One critique of an EFA article
One homework on CFA and validity
One critique of a CFA article
GRADING SYSTEM
The course uses the standard grading cutoffs.
H = 94-100
P = 80-93
L = 70-79
F = 69 and below
The final grade will be based on evaluation of seminar participation and written assignments.
One hundred points will be distributed as follows:
30
Cognitive testing paper

POLICY ON INCOMPLETES AND LATE ASSIGNMENTS
An automatic 10% reduction in score will be made for late papers (papers turned in after
the date and time given as deadlines).
POLICY ON ACADEMIC DISHONESTY
Original work is absolutely expected. Submitted work must conform to the Honor Code
of the University of North Carolina. For information on the UNC-CH Honor Code, including
guidance on representing the words, thoughts, and ideas of others, see: http://honor.unc.edu/
Please note that plagiarism is defined in the Instrument of Student Judicial Governance, Section
II.B.1 as, ―…the deliberate or reckless representation of another's words, thoughts, or ideas as
one's own without attribution in connection with submission of academic work, whether graded
or otherwise.‖ In keeping with the UNC Honor Code, if reason exists to believe that academic
dishonesty has occurred, a referral will be made to the Office of the Student Attorney General for
investigation and further action as required. See the School of Social Work Writing Style Guide
(on the School’s Website at the ―for current students‖ link) for information about plagiarism.
Students must not discuss homework or paper assignments or topics evaluated with those
assignments once they have been distributed. Graded work is expected to reflect totally
independent work. On the other hand, students are encouraged to consult written and online
resources on assignment topics (as long as they don’t post questions related to their assignments).
Code of Honor Affirmation. All written products in the course must have a signed Honor
Code statement. Papers without this affirmation will not be accepted. The statement should read
as follows: I have neither given nor received any unauthorized assistance on this assignment.
POLICY ON ACCOMMODATIONS FOR STUDENTS WITH DISABILITIES
Students with disabilities that affect their participation in the course and who wish to
have special accommodations should contact the University’s Disabilities Services and provide
documentation of their disability. Disabilities Services will notify the instructor that the student
has a documented disability and may require accommodations. Students should discuss the
specific accommodations they require (e.g. changes in instructional format, examination format)
directly with the instructor.
POLICIES ON THE USE OF ELECTRONIC DEVICES IN THE CLASSROOM
Use of electronic devices for non-class related activities (e.g. checking email, playing
games) is not acceptable.
