may not be true for all cultures that increasing bredth and depth would cause more intimacy in the relationship
Tang et al 2013 reviewed research on disclosure
he found that women and men in the us (individualist culture) were more likely to reveal thought about sex than men and women in china (collectivist culture)
Though self disclosure was low in china, satisfactory level remained the same between the two countries
limited explanation as it is based off findings from an individualist culture which cannot be generalised to other cultures
