Chapter 9: Problem 19

Does peer victimization during adolescence have an impact on depression in early adulthood? A recent study in the United Kingdom examined data on 3898 participants for which they had information on both victimization by peers at age 13 and the presence of depression at age 18 . The study found more than a twofold increase in the odds of depression between children who were not victimized and those who were frequently victimized." 20 This is an example of (a) an observational study. (b) a randomized comparative experiment. (c) a matched pairs experiment.

Short Answer

Expert verified
The study is an observational study.

Step by step solution

01

Understand the Studies Types

Begin by clarifying the different types of studies mentioned: - An **observational study** involves observing subjects and measuring variables of interest without assigning treatments or interventions. - A **randomized comparative experiment** involves randomly assigning subjects to different treatment groups and comparing outcomes. - A **matched pairs experiment** is a special type of randomized experiment where subjects are paired based on similar characteristics and assigned to different treatments within each pair.
02

Analyze the Study Characteristics

Examine the details of the study described in the exercise. Here, the study examines data collected on participants regarding victimization at age 13 and depression at age 18 without any intervention or treatment assignment. The study observes natural occurrences of victimization and subsequent depression.
03

Determine the Study Type

Because the study involves observing and gathering data on naturally occurring events without any manipulation or intervention, it fits the definition of an **observational study**. The researchers merely collected data and drew conclusions based on what they observed without assigning participants to any specific groups or conditions.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Peer Victimization
Peer victimization refers to the experience of being targeted by peers for harmful actions, such as bullying or social exclusion. This can include physical, verbal, or cyberbullying. Adolescents who face victimization may encounter various negative outcomes, both immediately and later in life. For example, they might feel isolated, anxious, or may even start to doubt their self-worth. These experiences can also lead to more severe issues like depression, especially if the victimization is frequent or particularly severe.
It's essential to recognize the signs of peer victimization early on, such as sudden changes in behavior, avoiding school, or unexplained injuries. Addressing these issues early can help to alleviate the possible long-term adverse effects. Support from peers, teachers, and family can play a crucial role in mitigating the negative impact and fostering a safer social environment for affected individuals.
Adolescent Depression
Adolescence is a critical period for mental health, as teenagers undergo significant psychological, social, and biological changes. Depression during this time can manifest as prolonged periods of sadness, lack of motivation, irritability, and withdrawal from activities and relationships.
There are various factors that can contribute to adolescent depression, such as genetic predispositions, family history, stress, trauma, and peer victimization. The impact of depression during adolescence can be profound, affecting academic performance, social interactions, and overall well-being. If depression is left untreated, it may carry over into adulthood, leading to lifelong challenges. Recognizing symptoms early and seeking mental health support is crucial. This can involve therapy, counseling, and in some cases, medication. Schools and communities can support by offering programs to raise awareness about mental health and providing resources for those in need.
Study Types
Understanding different study types is crucial for interpreting research results effectively. Among the various types of studies, an observational study is most relevant to the topic of peer victimization and adolescent depression. In an observational study, researchers simply observe and record data on subjects without intervention. This allows for the examination of relationships between variables as they naturally occur. The observational study described in the exercise collected data on adolescents aged 13 for peer victimization and then observed their mental health outcomes at age 18. This method doesn't manipulate variables but rather identifies potential correlations, such as whether victims of peer bullying are more likely to experience depression later. Other study types include randomized comparative experiments, which involve assigning participants to different groups to compare outcomes after interventions, and matched pairs experiments, which pair subjects with similar characteristics before assigning different treatments. Each type serves its purpose in research and helps answer different scientific questions.

Treating sinus infections. S?nus infections are common, and doctors commonly treat them with antibiotics. Another treatment is to spray a steroid solution into the nose. A well-designed clinical trial found that these treatments, alone or in combination, do not reduce the severity or the length of sinus infections. 33 The clinical trial was a completely randomized experiment that assigned 240 patients at random among four treatments as follows: (a) The report of this study in the Journal of the American Medical Association describes it as a "double-blind, randomized, placebocontrolled factorial trial." "Factorial" means that the treatments are fomed from more than one factor. What are the factors? What do "double-blind" and "placebo- controlled" mean? (b) If the random assignment of patients to treatments did a good job of eliminating bias, possible lurking variables such as smoking history, asthma, and hay fever should be similar in all four groups. After recording and comparing many such variables, the investigators said that "all showed no significant difference between groups." Explain to someone who knows no statistics what "no significant difference" means. Does it mean that the presence of all these variables was exactly the same in all four treatment groups?

Shared Pain and Bonding. Although painful experiences are involved in social rituals in many parts of the world, little is known about the social effects of pain. Will sharing painful experiences in a small group lead to greater bonding of group members than sharing a similar nonpainful experience? Fifty- four university students in South Wales were divided at random into a pain group containing 27 students, with the remaining students in the no-pain group. Pain was induced by two tasks. In the first task, students submerged their hands in freezing water for as long as possible moving metal balls at the bottom of the vessel into a submerged container; in the second task, students performed a standing wall squat with back straight and knees at 90 degrees for as long as possible. The no-pain group completed the first task using room temperature water for 90 seconds and the second task by balancing on one foot for 60 seconds, changing feet if necessary. In both the pain and no-pain settings, the students completed the tasks in small groups, which typically consisted of four students and contained similar levels of group interaction. Afterward, each student completed a questionnaire to create a bonding score based on answers to questions such as "I feel the participants in this study have a lot in common," or \({ }^{*}\) I feel I can trust the other participants."11 (a) Outline the design of the experiment, following the model of Figure 9.4. (b) Explain how you will randomly assign the subjects at random to the two groups, and then carry out this randomization using software, the Simple Random Sample applet, or Table B beginning at line 125 . (c) Why do you think the experimenter had students in the no-pain group complete similar pain-free tasks in small groups? Do you think this is important for the type of conclusion that can be reached? Explain.

Testosterone for Older Men. As men age, their testosterone levels gradually decrease. This may cause a reduction in lean body mass, an increase in fat, and other undesirable changes. Do testosterone supplements reverse some of these effects? A study in the Netherlands assigned 237 men aged 60 to 80 with low or low-normal testosterone levels to either a testosterone supplement or a placebo. The report in the Journal of the American Medical Association described the study as a "double-blind, randomized, placebo-controlled trial." 15 Explain each of these terms to someone who knows no statistics.

Quitting Smoking and Risk for Type 2 Diabetes. Researchers studied a group of 10,892 middle-aged adults over a period of nine years. They found that smokers who quit had a higher risk of diabetes within three years of quitting than either nonsmokers or continuing smokers. \({ }^{4}\) Does this show that stopping smoking causes the short-term risk for Type 2 diabetes to increase? (Weight gain has been shown to be a major risk factor for developing Type 2 diabetes and is often a side effect of quitting smoking. Smokers also often quit due to health reasons.) Based on this research, should you tell a middlle-aged adult who smokes that stopping smoking can cause diabetes and advise him or her to continue smoking? Carefully explain your answers to both questions.

Does exposure to aircraft noise increase the risk of hospitalization for cardiovascular disease in older people ( 265 years) residing near airports? Selecting a random sample of approximately 650,000 Medicare claims, it was found that about 75,000 people had zip codes near airports and the remaining 575,000 did not. The proportions of hospital admissions related to cardiovascular diseases were computed for those with zip codes near airports and those who did not have zip codes near airports. A larger proportion of admissions for cardiovascular disease was found for older people living in zip codes near airports. Which of the following statements is correct? (a) Because this is an observational study, living in a zip code near an airport may or may not be causing the increase in the proportions of admissions for cardiovascular disease. (b) Because of the large sample sizes from each group, we can claim that living in a zip code near an airport is causing the increase in the proportion of admissions for cardiovascular disease. (c) Because this is an experiment, but not a randomized experiment, we can still conclude that living in a zip code near an airport is causing the increase in the proportions of admissions for cardiovascular disease.
