Sprecher and Hendrick (2004) - strong correlation between several measures of satisfaction and self-disclosure in hetero couples
Men and women who used SD and those who believed their partners also disclosed = more satisfied with and committed to their romantic relationship
Supports concept of SD being a key component of committed romantic relationships
Strength: Real-life application?
Hass and Stafford (98) - 57% of gay men and women - open and honest SD was a maintenance strategy
Couples used to 'small talk' can be encouraged to increase SD in order to deepen their own relationships
Highlights: Importance of SD and suggests - theory can be used to support people having relationship problems
Limitation: doesn't apply to all cultures?
Tang et al (2013) concluded - people in the US disclose significantly more sexual thoughts and feelings than people in China - collectivist culture
Both levels of SD are linked to relationship satisfaction in those cultures - the pattern of SD is different
Social penetration theory - limited explanation of romantic relationship - not necessarily generalisable to other cultures
Limitation: SD is linked to relationship breakdown?
Sometimes breakdown of relationship is characterised by a reduction in SD - not always the case
Duck's (2007) phase model of the breakdown of relationships- couples often discuss their relationship with each other in intimate detail - this may not be sufficient to save the relationship
Suggests: increased SD may not always lead to positive developments in a relationship
Limitation: Much of the research is correlational?
Studies such as Sprecher and Hendrick (2004) - a positive correlation between SD and satisfaction
However - can't assume the relationship is a casual one
Suggests: such research provides only limited support for the theory
