Relationship Formation

46.3K
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,...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Discrepancy and Its Effects

331
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Ending Relationships

201
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Relationship Growth

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...

Social Relationships and Well-Being

327
The significance of social relationships in psychological well-being is a well-established area of inquiry within social psychology. Research consistently demonstrates that the presence of meaningful, supportive relationships enhances emotional health, while the absence or deterioration of such connections can contribute to psychological distress. Relationships serve as a foundation for emotional support, identity, and social belonging, all of which are critical to an individual’s overall...

Summary
This summary is machine-generated.

Relationship functioning suffers when couples have differing marijuana use habits. Greater differences in use frequency correlate with lower satisfaction, responsiveness, and more conflict and aggression over time.

Area of Science:

  • Psychology
  • Sociology
  • Substance Use Research

Background:

  • Discrepant substance use between intimate partners is linked to poorer relationship outcomes.
  • Previous research suggests that differences in alcohol and drug use frequency impact relationship functioning.

Purpose of the Study:

  • To investigate the association between marijuana use discrepancy in couples and relationship functioning.
  • To examine the Actor Partner Interdependence Model (APIM) in the context of marijuana use differences.

Main Methods:

  • Longitudinal study with 4 waves of data over 10 months.
  • Multivariate, two-level models analyzing within-couple and between-couple effects.
  • Sample of heterosexual couples (ages 18-30) with at least one marijuana user (≥2 times/week).

Main Results:

  • Greater marijuana use frequency discrepancy was associated with poorer relationship satisfaction, perceived partner responsiveness, and increased conflict.
  • Negative within-couple discrepancy effects were observed: poorer functioning when use difference exceeded the couple's norm.
  • Effects were consistent regardless of which partner used more; some negative effects linked to higher female use.

Conclusions:

  • Marijuana use discrepancy dynamically impacts relationship functioning over time.
  • The magnitude of the difference in use, not just the use itself, is crucial for relationship quality.
  • Findings highlight the importance of concordant substance use for relationship well-being.
