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...

Revisionist Views of Adolescent and Adult Cognition

310
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...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.5K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Design Example: Vintage Mixing Console

581
A sound engineer at a music company recently encountered a problem. The output from their newly acquired studio's vintage mixing console was too low for the requirements of modern recording equipment. To rectify this situation, the engineer decided to design an audio pre-amplifier using an operational amplifier (op-amp) to boost the signal level.
The specifications for the pre-amplifier were clear. It needed to amplify the audio signal by a factor of 10, have an input impedance above 10...

Methods of reducing fever

1.4K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Area of Science:

  • Digital health interventions
  • Eating disorder (ED) risk factors
  • Adolescent mental health

Background:

  • eHealth interventions show promise for reducing eating disorder (ED) risk factors.
  • High dropout rates and low adherence challenge current eHealth interventions.
  • Mobile applications offer a scalable approach to address ED cognitive risk factors.

Purpose of the Study:

  • To analyze the usability and acceptability of the GGED-AD mobile app.
  • To assess the potential of GGED-AD in reducing cognitive risk factors for eating disorders (EDs) in adolescents.
  • To identify areas for improvement in GGED-AD for enhanced real-world adoption.

Main Methods:

  • Convergent mixed-methods approach utilized.
  • Study involved 42 adolescents (mean age 13.98 years) with eating disorder (ED) risk factors.
  • Usability and acceptability of the GGED-AD mobile app were systematically evaluated.

Main Results:

  • GGED-AD demonstrated satisfactory usability and acceptability among adolescent participants.
  • Participants found the app easy to use, attractive, and encouraging of positive behaviors.
  • Some participants experienced difficulties understanding specific app content, indicating areas for refinement.

Conclusions:

  • GGED-AD shows potential as an eHealth intervention for adolescents at risk of eating disorders (EDs).
  • App design improvements, particularly in content clarity, are recommended to enhance user adherence and real-world effectiveness.
  • Findings offer insights for developing and optimizing future digital health tools for ED prevention.
