Relationship Formation

40.9K
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,...

Erikson's Theory on Socioemotional Development during Adulthood

257
Erik Erikson's theory of psychosocial development outlines a series of stages through which individuals progress across the lifespan. Each stage involves a psychosocial conflict that significantly influences personal growth and well-being. Three key stages — intimacy versus isolation, generativity versus stagnation, and integrity versus despair — highlight the developmental challenges faced in adulthood.

Factors Affecting Illness01:18

Factors Affecting Illness

4.4K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Erikson's Theory on Socioemotional Development during Adolescence

334
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...

Social Facilitation01:04

Social Facilitation

32.8K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Theory of Romantic Attachment in Adulthood

44.3K
Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.

Area of Science:

  • Gerontology
  • Public Health
  • Social Epidemiology

Background:

  • Frailty is defined by loss or decline and predicts negative health outcomes.
  • Factors associated with frailty include biological, psychological, economic, and social elements.
  • Social vulnerability, a stable state, may increase frailty risk.

Purpose of the Study:

  • To assess if social vulnerability increases the risk of incident frailty.
  • To investigate the relationship between social status and the development of frailty.

Main Methods:

  • 1531 participants aged 65+ from the PAQUID cohort study.
  • Cox regression models analyzed the association between the Social Vulnerability Index (SVI) and Frailty Index (FI) over 27 years.
  • SVI comprised 28 social items; FI comprised 25 health items.

Main Results:

  • Higher SVI was associated with increased risk of incident frailty (HR=3.85) after adjusting for age and sex.
  • The association remained significant after controlling for IADL disability, comorbidities (HR=3.40), and MMSE (HR=2.34).

Conclusions:

  • Poor social status is a significant risk factor for frailty.
  • Results support distinguishing frailty (an ongoing decline) from fragility (a stable state due to social conditions).
  • Social vulnerability should be considered in frailty risk assessment.
