Insights

Child maltreatment, including abuse and neglect, significantly impacts cognitive function, high school completion, and employment in young adulthood. Early intervention is crucial for affected youth.

Area of Science:

  • Developmental Psychology
  • Public Health
  • Child Welfare

Background:

  • Child maltreatment is linked to negative outcomes, but its long-term cognitive and educational effects are understudied.
  • A birth cohort design is essential for tracking developmental trajectories from early life into adulthood.

Purpose of the Study:

  • To examine the association between child maltreatment and cognitive function, high school completion, and employment at age 21.
  • To investigate the specific impacts of abuse and neglect on young adult outcomes.

Main Methods:

  • A longitudinal birth cohort study followed 7223 participants from prenatal stages to age 21.
  • Child maltreatment data was obtained through official government records.
  • Statistical analyses adjusted for sociodemographic and perinatal factors.

Main Results:

  • Child maltreatment was associated with a significant decrease in cognitive performance (Peabody Picture Vocabulary Test).
  • Maltreated individuals had threefold odds of not completing high school.
  • Those maltreated were more than twice as likely to be disengaged from education or employment at age 21.

Conclusions:

  • Child maltreatment, encompassing abuse and neglect, predicts poorer cognitive, educational, and employment outcomes in young adulthood.
  • Findings underscore the importance of child maltreatment prevention and support services for affected individuals.

Birth Control Methods01:22

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome01:11

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
