Scenario
Agency XYZ offers a 12–week parenting education program that aims to
improve childrearing competence and nurturing empathy among parents who
report difficulty in caring for their young children (re: 2–5 years old). Classes
are convened once a week on Wednesday evenings from 7:00 p.m.–9:00
p.m. Enrollment is capped at 15 parents per each 12–week session. Once
parents complete and return the Informed Consent, they are enrolled in the
program on a “first–come, first–served” basis. Prior to the start of the first
class, parents are pre–tested on their levels of childrearing competence and
nurturing empathy. Upon conclusion of the 12th class, parents are post–
tested on their levels of childrearing competence and nurturing empathy. You
have been asked to evaluate the (potential) progress parents have made in
their levels of childrearing competence or nurturing empathy from pre– to
post–test.
Section I
Based on the above scenario, write a research question that could be used to
guide your evaluation. Ensure your research question contains two variables
(i.e., one IV and one DV; delineate which is the IV and which is the
DV). Please note, you are choosing between assessing levels of childrearing
competence or nurturing empathy.
Section II
Based on your research question, state a testable hypothesis. Identify an
instrument you could use to operationalize/measure the DV (remember, as
“hinted” above, your DV will either be childrearing competence or nurturing
empathy). Provide a reference to an article in which this instrument was
used. Explain/provide a rationale for your choice of instrument.
Section III
Consider the research design that is implied in the scenario and answer the
following: (a) identify two strengths and two weakness pertaining to the
internal and external validity of the study; (b) discuss how the strengths
support and weaknesses hinder the causal influence that the parenting
education program improves parents’ levels of childrearing competence and
nurturing empathy; and (c) address how the generalizability (for external
validity) and causal influence (for internal validity) could be improved in
regards to future applications of this program.
Please note, initial posts should be between 300 and 500 words. As
applicable, relate and support your initial post with what you learned from the
course materials for this week and any other resources you want to share
(e.g., from prior courses), using standard APA citations. In addition to starting
a discussion by making your initial post, you are required to read the postings
of fellow students and respond to at least two other initial posts. Your
responses should elaborate on the initial postings of your colleagues (e.g.,
exchange ideas, debate points, and/or add to their ideas) and should be
approximately 150 words each.
