Family and friends are central to human life and well-being. Most people maintain both family and friendship relationships and these relationships might show interdependencies that have scarcely been addressed. We examined the relative frequency of daily contact with family and friends (i.e. friends/family-contact) and its link with personality traits and affective well-being. In an experience sampling study with 396 participants (Mage= 40 years, range 14–88 years, 52% females), we studied how friends/family-contact was associated with Big Five traits and affective well-being across six daily measurements on nine days (average of 55 assessments). Most participants reported more daily contact with family than friends (i.e. held a family orientation), but individual differences were substantial, moderately stable over time, and largely independent from Big Five traits. With advancing age, participants were relatively more often with friends than family. Furthermore, participants were happier when they were with friends compared to family, and this effect was even stronger with higher extraversion. We discuss how examining friends/family-contact extends previous knowledge on personality differences in social relationships, and how this concept yields promising, yet challenging, future directions in personality-relationship associations.
