9. 9 1. discuss sex similarities and differences in same-sex friendship. By the end of today’s class, you should be able to: 2. identify desired characteristics and sources of relationship satisfaction in same-sex friendship. 3. identify the age period during which sex differences in self-disclosure emerge.

10. 10 6. review research findings regarding the social desirability of self-disclosure among females and males. 5. discuss the relation between self-disclosure and gender. 4. define the term: co-rumination.

11. 11 Are there sex similarities in same-sex friendship? A number of sex similarities in same-sex friendships have been identified: 1. Friendship network size: Mean = 5 – 8 (Urberg et al., 1995).

12. 12 2. Desired characteristics:  Affective (i.e., emotional) support more important than instrumental (i.e., task-oriented) support (Burleson et al., 1996).  Trust and authenticity most important (Parker & de Vries, 1993).  Seek friends with similar characteristics (Berndt, 1982; Linden-Anderson et al., 2009).

13. 13 3. Sources of relationship satisfaction: Include support, enjoyment, and equal power status (Bank & Hansford, 2000; Fehr, 2000; Reisman, 1990; Veniegas & Peplau, 1997). 4. Knowledge of friends/relationship (Simpkins et al., 2006).

14. 14 Are there sex differences in same-sex friendship? A number of sex differences in same-sex friendships have been identified: 1. Group size during play: Females tend to play in dyads; males tend to play in groups (Baines & Blatchford, 2009; Rose & Rudolph, 2006). 2. Best friends: Females are more likely than males to report having a best friend and to be “clique” members (Urberg et al., 1995).

15. 15 3. Self-disclosure:  Female-female friendships are characterized by greater self-disclosure than male-male friendships (e.g., Buhrmester & Furman, 1987; McNelles & Connolly, 1999; Sheets & Lugar, 2005).  Sex differences in self-disclosure appear in childhood and are consistent across age groups (Buhrmester & Furman, 1987; Swenson & Rose, 2009):

17. 17 Mean Intimate Disclosure Scores in Same-Sex Friendships for Women and Men (Sheets & Lugar, 2005) Intimate Disclosure Scores

18. 18  Among females, self-disclosure is not influenced by gender. Among males, masculinity is negatively correlated with self-disclosure and femininity is positively correlated with self-disclosure (Winstead et al., 1984; also see Shaffer et al., 1996).  When self-disclosing, females are more likely than males to engage in “co-rumination” (Rose, 2002; Rose et al., 2007).

19. 19  Research suggests that males are less likely to self- disclose than females because self-disclosure among males is less socially desirable:

20. 20 Derlaga and Chaikin, 1976 (also see Collins and Miller, 1994; Mickelson, Helgeson, & Weiner, 1995) Female and male participants read a case study and evaluated the target’s levels of adjustment and likeability. The stories manipulated the sex of the target and the level of self-disclosure that the target engaged in with respect to a traumatic event.

21. 21 Male Target Female Target Psychological Adjustment as a Function of Level of Disclosure and Sex of Discloser (Derlaga & Chaikin, 1976) Psychological Adjustment

22. 22 Also found that self-disclosure was positively correlated with likeability scores among females but not among males.
