Showing Affection: How Behaviour Sustains Friendships

How Do You Show Affection in Friendships?

Among the many behaviours that shape friendships, affectionate behaviour holds a special place. In Hays’ (1984) 12-week longitudinal study, it was the only behavioural category that remained stable across all four measurement points — both in its correlation with friendship intensity and in its frequency within successful friendships — unlike companionship, communication, and consideration, which showed considerable fluctuations.

Particularly striking was the early time point: after just three weeks of acquaintance, affectionate behaviour was already significantly more strongly correlated with friendship ratings than all other behavioural categories. While communication showed the weakest correlation at that point (r = .27), affection already reached r = .54. This suggests that affectionate behaviour plays a decisive role in initiating the friendship bond.

Small Gestures, Big Impact

Affectionate behaviour in the FOC instrument includes expressions of emotional connectedness — both positive and negative feelings towards the other person. Concrete examples include: “I told O something I like about him/her,” “I called O just to say hello,” or “O and I performed a ritual of our friendship.” These behaviours signal to the other person that the relationship is valued and goes beyond mere utility.

Clear gender differences also emerged: men showed significantly less affectionate behaviour than women. These differences were already apparent during scale construction — men barely assigned any affectionate behaviours to the casual intimacy level, while women named 18 such items. Hays suggests that this finding contributes to men developing fewer successful close friendships than women (cf. Lewis, 1978). Affection thus appears to serve a dual function: it initiates the friendship bond and sustains it through periods of less frequent interaction.

Affection vs. Appreciation

The special role of affection is consistent with Rubin’s (1970) concept of the “attachment” component in romantic relationships and La Gaipa’s (1977) factor of “positive regard” in friendships. The stability of affectionate behaviour over time contrasts with the dynamic changes in other behavioural categories and suggests that affective bonding signals serve a different function than instrumental or informational exchange. The gender differences confirm earlier findings by Booth (1972) and Rands and Levinger (1979) on lower emotional expressiveness among men in same-gender friendships.

Measuring affectionate behaviour in the FOC had to be collapsed to a single intimacy level because of the strong gender differences, which limits its discriminative power. It remains unclear whether the high correlation between affection and friendship ratings reflects a genuine causal effect or a conceptual overlap — someone who considers a person a friend may automatically report more affectionate behaviour. The cultural specificity of affection expressions should be noted: in cultures with different norms of emotional expressiveness, affection may play a different role. Data from the other dyad member on the reciprocity of affectionate behaviour are also missing.
