Summary
This study identified distinct peer victimization groups in middle school students using latent class analysis (LCA). Findings reveal a consistently small, highly victimized group experiencing increased depression and safety concerns.
Area of Science:
- Psychology
- Sociology
- Criminology
Background:
- Peer victimization is a significant issue during adolescence.
- Understanding distinct victimization patterns is crucial for targeted interventions.
- Previous research often categorizes victimization by type rather than degree.
Purpose of the Study:
- To empirically identify distinct groups of victimized students in middle school using Latent Class Analysis (LCA).
- To examine the prevalence and characteristics of these victimization groups over time.
- To assess the concurrent and subsequent psychological impact (safety, depression) on victimized students.
Main Methods:
- Latent Class Analysis (LCA) applied to self-reported peer victimization data.
- Longitudinal data collected from approximately 2,000 urban public middle school students across three academic years (grades 6-8).
- Analyses conducted independently for each semester to identify victim classes based on victimization degree.
Main Results:
- Three distinct victim classes were consistently identified across all semesters, primarily differentiated by the degree of victimization.
- The most victimized class, representing the smallest proportion of students, decreased from 20% in sixth grade to 6% by eighth grade.
- Students in the most victimized class reported lower concurrent school safety and higher depression one semester later.
Conclusions:
- Latent Class Analysis effectively identifies distinct, empirically-based peer victimization groups in middle school.
- A small but persistent group of highly victimized students faces significant psychological distress, including reduced safety and increased depression.
- These findings underscore the importance of considering victimization severity and its longitudinal impact in school-based prevention and intervention efforts.

02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:24Attachment Styles
Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...
02:16Stereotype Content Model
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
01:28Conduct Disorder
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
01:29Theory of Attribution II: Kelley's Covariation Theory
Attribution theory plays a crucial role in social psychology, helping to explain how individuals interpret the causes of behavior. One prominent model within this field is Harold Kelley's covariation theory, which provides a systematic approach to determining whether internal traits or external circumstances drive a person's actions. The model posits that individuals rely on three key types of information—consensus, consistency, and distinctiveness—to make these judgments.Consensus: Comparing...
02:12Relationship Formation
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
