Review of last week
• Which one is not the purpose of a “process
study”?
1. Fidelity study of the intervention
2. The outcome of the intervention
3. Whether the intervention was implemented
correctly
4. How well the staff were trained in the new
intervention

Review of last week
• Which type of study – efficacy or effectiveness, is
conducted with more rigorous research methods?
• True or false: an intervention is determined to be a “best
practice” when the professional community comes to
consensus about it being one.
• True or false: there is no relationship between research
methods and an agency’s attempts to improve the
quality of its services.
• True or false: one reason why a desired outcome isn’t
achieved could be that the target population was not
accurately recruited

Purposes of Literature Review
in Research
1) To focus the research topic and questions
2) To gather statistics about the target population and/or
extent of the problem you’re addressing
3) To find relevant theory for your topic
4) To find out what methods have been done to answer
the research questions
5) To look for gaps in the research
a) Target populations not yet studied or excluded
b) Interventions not yet studied
c) Methods not yet conducted
6) What were implications of the study, and what were
the recommendations for further study?

Library Resources
http://library.sjsu.edu/online-tutorials/onlinetutorials
For example:
• Finding Scholarly, Peer-Reviewed Articles
• Topic development-http://library.sjsu.edu/video/art-topicdevelopment
ScWk 240 9/17/12

Bibliography
• Peer reviewed articles
http://library.sjsu.edu/video/finding-scholarly-peer-reviewed-articles
– For the Bibliography, aim for 15 out of the
minimum 20 required
– Websites ok, but the priority ones are:
• Research organization sites
• Policy sites
• Online government reports
• Journals relevant to social work: see Rubin & Babbie
appendix, “Using the Library”
• APA—everything double spaced

Student report #1
Describe the relationship between theory and
hypotheses.

The Role of Theory in Research
• Definition of theory: Definition of theory in the social
sciences: “a systematic set of interrelated statements
intended to explain some aspect of social life or enrich our
sense of how people conduct and find meaning in their daily
lives.” (Rubin & Babbie)
• What are the purposes of theory in developing and
conducting research?
– Makes explicit any underlying assumptions
– Justifies how or why we think something is true (such as an
hypothesis) or why one thing can cause another thing to
occur or predict its occurrence
• Such, as: What do you think causes people to behave the way
they do? Genetic predisposition? Environmental factors?
Psychological temperament?
• Discussion: why would you expect that social activity would
allow older adults to maintain cognitive functioning?

The types of theories relevant to social
work research
• Theories of human behavior (developmental theories, stress
& coping, etc.)
• Theories about groups, organizations and communities
• Political, sociological and economic theories
• Theories about environment and culture (ecological theory,
acculturation theory, feminist/gender role theories, etc.)
• Program theory (explains how a practice, program or
intervention should work based on the objectives of the
program and other theories)

The role of theory in the types of
SW research
Type of SW Research
Role of Theory
Descriptive research
No role of theory
Explanatory research
Very important role:
•Explains the relationship among variables
•Deductive reasoning—theory is tested
Exploratory research
Very important role:
•Theory is necessary, but underdeveloped
•Inductive reasoning—theory is
developed from observation
ScWk 240 9/17/12
12
Deductive reasoning
• Deductive reasoning--we develop hypotheses
based on a theory
– If X happens, then Y is true (or false), or
– X and Y are (or are not) related, or
– The more X occurs, the more (or less) Y occurs
• “Hypothesis”: a testable statement about
empirical reality
Example: Parent Mentor program and Stress
Coping Theory

Student report #2
What’s the difference between an independent
and dependent variable?
ScWk 240 9/17/12
14
Independent and Dependent Variables
•What is a variable? Observable characteristics that vary among
individuals
• Independent variable— variables used to explain, predict or cause
another variable. (Hint—“independent” implies that these variables
are unaffected by the predicted variable.)
• Dependent variable— the variable that is assumed to be affected,
caused or predicted by others. (Hint: “dependent” on others.)
•The opposite of variable is constant. What’s the difference?
–For young women between 16-25, does involvement in criminal justice
have anything to do with extent of prior abuse?
•Name the IV, the DV and the constant
•Can you identify a theory that might explain this statement?
ScWk 240 9/17/12
15
Name the IVs (Xs) and DVs (Ys)
• Name the IV and DV:
– Is educational attainment related to income level?
– What role does self esteem play in a young adult’s
job interview abilities?
– Do those receiving medication for depression with
case management have better outcomes (less
depression) than those receiving only case
management? (Hint—”outcomes” are always
dependent variables)

Student report #3
What are “attributes” of a variable? Give two
examples.
ScWk 240 9/17/12
17
Attributes
“Attributes” – characteristics of persons or
things (the choices of a variable’s
characteristics)
What are the likely attributes of these variables?
• Gender
• Ethnicity
• Income
• GPA
• Employment status
ScWk 240 9/17/12
18
Something like this “might” be on a test…
“For uninsured adults with substance abuse problems
in San Jose, males are more likely than females to be
referred to follow up care.”
– What is the independent variable? __________ What are
its attributes?
– What is the dependent variable? _________ What are its
attributes?
– What is the constant?
– What would the research question for this study?
• Note: Hypotheses and research questions can be stated in terms of
variables; OR in terms of their attributes

Topics for Student Reports, Week 3
1. Why is it important to protect research subjects? What areas
need protecting? Valerie
2. What is the difference between “confidentiality” and
“anonymity”? Arlene
3. What is “culturally competent measurement” in research?
Relate this to one or more (of the 5) areas of the
Transcultural Perspective. Elisse
