A) positive.
B) negative.
C) curvilinear.
D) causal.

Question 7

A) direct observables.
B) indirect observables.
C) constructs.
D) a nominal variable.
E) validity.

Question 8

A study tests the hypothesis that the provision of social work intervention will reduce the school dropout rate.Iinds that social work intervention reduces the dropout rate only of children whose families are experiencing high levels of family stress.In this study,what type of variable is "level of family stress"?

A) independent variable.
B) dependent variable.
C) moderating variable.
D) It could be an independent or dependent variable; it depends on whether it is stated first or second in the hypothesis.

Question 9

Extraneous variables are variables that are irrelevant to a particular study.

Question 10

Some operational definitions of a particular variable can be more valid than other operational definitions of the same variable.

Question 11

One possible operational definition of optimism is degree of hopefulness.

Question 12

The following is an example of a good hypothesis: "Social work practitioners who work in mental health agencies do not care adequately for the chronically mentally ill."

Question 13

In social work studies testing hypotheses involving the variable "level of social functioning" that variable is:

A) always the dependent variable.
B) always either the dependent or control variable.
C) always the independent variable.
D) an independent, dependent, or control variable, depending on what is being conceptualized and postulated in any given study.

Question 14

The real and observable things that give evidence of the presence or absence of the concept being studied are called:

A) dimensions
B) indicators.
C) concepts.
D) measures.
E) definitions.

Question 15

If we find that self-esteem is higher among children who are more active in sports,we have found what type of relationship?

A) positive.
B) negative.
C) curvilinear.
D) causal.

Question 16

Researchers who operationally define the severity of substance abuse as a total score on a scale with multiple questions asking research participants to indicate how often they use various types of substances are using what source of data for their operational definition?

A) Direct observation.
B) Self-report.
C) Available records.
D) Direct observables.

Question 17

Which of the following is NOT an operational definition of degree of homophobia?

A) a score on a scale measuring attitude about homosexuality.
B) whether or not participates in protests against gay marriage.
C) view of homosexuality.
D) number of derogatory statements made about homosexuality in a conversation about it.

Question 18

If level of marital satisfaction increases when socio-environmental stress decreases,that would be an example of a positive relationship:

Question 19

Concepts are

A) empirical measurements.
B) variables.
C)mental images.
D) hypotheses.
E) definitions.

Question 20

Measuring how practitioners feel about working with minority clients when you really want to know how well informed they are about cross-cultural practice is a problem of operationalization concerning

A) the use of single or multiple indicators.
B) how observations are going to be made.
C) the specific dimensions of the variable to be studied.
D) the relevant range of variations.
E) the degree of precision needed between extremes.

Question 21

Construct two hypotheses of interest to social workers.One should predict a positive relationship,the other a negative relationship: Identify the independent and dependent variables in each hypothesis.Identify a control variable for each hypothesis.Operationally define each variable.

Question 22

Illustrate how a child's level of behavioral problems could be operationally defined in three different ways using three different sources of data.

Question 23

Construct a hypothesis predicting that a particular intervention will be effective regarding a particular long-term outcome.Then identify a mediating variable and a moderating variable that could be assessed in testing the hypothesis.Explain why one variable is the mediating variable and the other is the moderating one.

Question 24

Discuss how the quantitative and qualitative perspectives on operational definitions differ.

Question 25

It is possible to have several indicators of only one concept.

Question 26

Examining police records of the number of arrests for domestic violence is an example of the use of self-report as a source of data for an operational definition.

Question 27

Concepts are mental images that summarize collections of seemingly related observations and experiences.

Question 28

If we study whether motivational interviewing is effective in treating substance abuse by the mechanism of increasing the likelihood that clients will complete substance abuse treatment programs,then whether clients complete such programs is our mediating variable.
