Strengths And Limitations Of Correlational Design

Correlational designs have been used in all areas of research. Forensic psychology research is no exception. As you have seen from your readings, many phenomena do not lend themselves to true experimental design. For example, an experimental research study that looks at the effect of viewing violent content, either on television or in video games, would be more challenging, both practically and ethically, than a similar study using a correlational design. Correlational research designs allow researchers to study behavior as it occurs naturally. However, to do so probably would compromise the ability to draw cause-and-effect conclusions.

To prepare for this assignment:

  • Review Chapter 9 in your course text, Research Methods for the Behavioral Sciences. Consider the strengths and limitations of using correlational data, in general, and as it relates to research in forensic psychology or in forensic settings.
  • Review the article, “Forensic Psychology: An Empirical Review of Experimental Research.” Focus on the strengths and limitations of empirical and correlational design.
  • Using the Walden Library, select and review two research articles covering different topic areas, both of which use a correlational design.
  • Think about the strengths and limitations of the correlational design used in each of the two research articles you chose.

The assignment (1–3 pages):

  • Briefly describe each of the studies in the two research articles you selected. Include a description of the results of the studies and the correlational relationship reported.
  • Explain the strengths and limitations of using a correlational design in each of the studies.

Ab Psy 2 Case Study Question Is Attached In The Bottom

The DSM is a classification manual used by professionals in the field of psychology. For this assignment, you will diagnose three clients. The vignettes for each client, “Case Study Vignettes,” are located in resources. For each client, indicate:

  • The diagnosis, discussing each criterion the client fits and does not fit for that diagnosis from the DSM-5 (which you should cite).

Select one of the clients and in a separate, final section of the paper, complete the following:

  • Analyze two recommended treatments for the client and explain why they would be recommended (one or both of these treatments should come from a current peer-reviewed journal article).
  • Support your analysis with a peer-reviewed journal article about the diagnosis you chose for this client.
  • How well does the article’s discussion of the diagnosis compare to the behaviors the client displays?
  • As a professional in the field of psychology, how would you use the information from the article to inform your professional behavior?
Additional Requirements

For this assignment, you are expected to meet the following requirements:

  • Title page: Include your name, course, date, and instructor.
  • ReferenceDSM-5, textbook, two or more peer-reviewed journal articles.
  • Written communication: Written communication is free of errors that detract from the overall message.

Case Study Vignettes

Anxiety, Trauma, Stressor, and Obsessive Compulsive Related Disorders

1. Fred

Fred was raised in Houston. His father and mother were both successful realtors. He is the middle of three brothers, who remain close. He remembers, “We never wanted for anything.” Fred was an A student in high school and college and a top athlete. He completed medical school and now practices as an anesthesiologist at a local hospital.

Fred experienced some emotional distress a number of years ago as he considered coming out and letting his family know he is homosexual. His father initially struggled with the news but came to accept it. Fred’s father is quite amiable towards Fred’s partner. Fred’s oldest brother was nonplussed by the news. Fred and his partner are welcomed in his brother’s home. Fred’s mother’s response was “I don’t believe it. Please never mention this again.” The youngest brother’s response was to accuse Fred of hurting mom.

Fred has again been experiencing emotional distress this past year as he and his partner discuss the idea of either marrying or having a commitment ceremony. Fred is certain that he wants to do this but struggles with the question of what to tell family members and whether to even invite his mother and youngest brother.

In this context Fred complains of daily panic attacks. These generally occur when he is getting ready for work or near the end of the work day. The panic attacks started several weeks after Fred was robbed at gunpoint at a subway station. This occurred four months ago. He stated he does not think he was particularly affected by the attack but wonders because the panic attacks started soon after. Following the attack, Fred decided he is not going to use the subway anymore because it is too dangerous. Fred has been commuting by bicycle even though it is often difficult to negotiate the city streets by bike.

Fred reports that there is no mental illness that he is aware of in his immediate family. He strongly suspects that his mother’s father was an alcoholic because he remembers his grandfather smelling of alcohol during his (Fred’s) childhood and because his mother refuses to have any alcohol in her home.

2. Phil

Phil is 20. He comes in because he is “stressed” now that he is not working. Phil reports that his first job was at a restaurant, but he quit because it was “too messy.” After work he would shower for hours to get the food smells out of his hair. Even after showering he would feel greasy and dirty. He next found work at a clothing store. Phil reports that he was initially very well regarded by his boss at the clothing store at which he worked. He worked hard, always making sure displays were orderly and the clothes were perfectly folded and arranged in order by size. His boss so appreciated the attention that he took with the displays that she made him the assistant manager and put him in charge of the other employees. She was relieved that she had a second in command so that she could leave the store under his supervision.

However, the boss soon became frustrated with Phil. He did little to help manage the employees or problem-solve difficulties. He did not seem able to field customer complaints. He did a poor job on some of the managerial tasks assigned to him. But he did continue to neatly fold the clothes and arrange them by size, even after the boss told him he should delegate this to another employee so he could focus on his role. After several warnings about this, Phil was eventually terminated.

Phil reported he had been married for a year but his wife left him because she found him controlling. He is not sure what this means but notes that they often argued because he got frustrated that she did not put things away where they belonged. She would especially get upset because he would try to clean up the kitchen when she was cooking, so “things wouldn’t get too messy.”

3. Stacey

Stacey is 35 years old and lives alone.  Stacey was married when she was 20 and was married for 4 years. The couple did not have any children. Stacey’s mother describes that Stacey was shy when she was little and tended to play alone with her dolls and stuffed animals. She had a brother who was ten years older than her. The family lived in the country and had a lot of pets and other animals, such as horses and chickens. Stacey loved the animals and was good at helping to care for them.

Stacey had a close childhood friend named Anna who she met in the first grade. The two girls would sometimes get to play at each other’s houses and sometimes would spend the night. When they were in the fourth grade, Anna’s family moved out of state. Stacey was small for her age and wore glasses. She became a target for other kids to make fun.

Following Stacey’s divorce, she became more reclusive. Stacey’s former husband, Chad, was critical of Stacey and left because in his words she “was a doormat with no personality.” She currently maintains a job as a cashier at a local grocery store. She has worked there for seven years and her employers are happy with her performance. She is highly accurate and efficient at her job. When she is off of work, she tends to stay home alone with her pets.

Four years ago Stacey enrolled in college thinking she might like to become a nurse. Several of her classes required her to give presentations in front of the class, and Stacey described that she was “paralyzed with fear” in thinking about public speaking. She was afraid she would not be able to get through her speech and that her classmates and teachers would make fun of her. She dropped those classes, and therefore was unable to move forward in her education.

Stacey says that she is content with her job and with living alone with her pets. She has three dogs, two cats, and several birds. All of the pets came to her through a pet rescue agency.  She states that pets are accepting and loving and don’t criticize.

Discussion: Research Design For One-Way ANOVA

Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will perform an article critique on ANOVA testing. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another.

To prepare for this Discussion:

· Review the Learning Resources and the media programs related to ANOVA testing.

· Search for and select a quantitative article specific to your discipline and related to ANOVA testing. Help with this task may be found in the Course guide and assignment help linked in this week’s Learning Resources. Also, you can use as guide the Research Design Alignment Table located in this week’s Learning Resources.

By Day 3

Write a 3- to 5-paragraphs critique of the article. In your critique, include responses to the following:

1. Which is the research design used by the authors?

2. Why did the authors use ANOVA test?

3. Do you think it’s the most appropriate choice? Why or why not?

4. Did the authors display the data?

5. Do the results stand alone? Why or why not?

6. Did the authors report effect size? If yes, is this meaningful?

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Evidence And Non-Evidence Based Treatment Options

Prior to beginning work on this discussion, please read both “Limitations to Evidence-Based Practice” and “Rationale and Standards of Evidence-Based Practice,”and listen to the Case Studies in Non-evidence Based Treatment Part One. On the last day of Week 5, listen to Case Studies in Non-evidence Based Treatment Part Two.

For your initial post, you will choose one of the case studies from this week’s audio file selection on which to base your remarks. Based on the available information, evaluate the symptoms and presenting problems for the patient in the chosen case study and propose a provisional diagnosis. Describe one evidence-based treatment for this diagnosis and provide a rationale for your choice. Research at least two peer-reviewed articles to support your evidence-based treatment selection.
