Summary
Sedentary behaviors like computer use and TV watching have different correlates in adolescents. Understanding these differences is key for developing effective interventions to reduce screen time and combat obesity.
Area of Science:
- Public Health
- Adolescent Health
- Behavioral Science
Background:
- Sedentary behavior is linked to obesity in youth.
- Targeted interventions require understanding specific sedentary behavior correlates.
- Leisure computer use and television viewing are prevalent sedentary behaviors in adolescents.
Purpose of the Study:
- To examine individual, family, and environmental correlates of leisure computer use.
- To examine individual, family, and environmental correlates of television viewing.
- To identify differences in correlates between these two sedentary behaviors in California adolescents.
Main Methods:
- Analysis of data from the 2005 California Health Interview Survey.
- Inclusion of 4,029 adolescents in the study sample.
- Use of linear regression analyses to identify correlates.
Main Results:
- Television viewing correlates: male sex, American Indian/African American race, lower income, lower physical activity, lower parent education, more parent work hours.
- Computer use correlates: older age, Asian race, higher income, lower physical activity, less parental knowledge, higher proportion of nonwhite/low-income neighbors.
- Physical activity was the only correlate similarly associated with both behaviors.
Conclusions:
- Correlates of adolescent television viewing and leisure computer use significantly differ.
- Understanding these distinct correlates is crucial for designing effective interventions.
- Reducing screen time is a viable strategy for combating adolescent obesity.

01:18Cognitive Development During Adolescence
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the recognition that people have...
02:57The Sense of Self: Reflected Self-Appraisal and Social Comparison
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
01:24Revisionist Views of Adolescent and Adult Cognition
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.
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;...
01:30Social Foundations of Self IV: Self in Digital Communication
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...
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.
