In an effort to develop a multidimensional theory of self-disclosure, the present research considered two dimensions of disclosure content—degree of personalness (intimacy) and valence (positiveness or negativeness)—as well as gender of the discloser, timing of disclosure in relationship development, and the recipient of disclosure. In Study I, the variables of personalness and valence were manipulated through the use of prototypical disclosure statements with subjects blocked by sex. Subjects were asked to use a scale indicating phases of relationship development to rate when they would likely disclose statements. The analysis revealed significant main effects for all three factors: personal-ness, valence, and gender, as well as a significant interaction between personalness and valence. In Study II, personalness and valence were again manipulated, along with blocking for sex. The variable of disclosure recipient (target) was manipulated by asking subjects to separately indicate whether or not they would disclose each statement to five targets: stranger, acquaintance, parent, friend, and spouse. The analysis revealed significant main effects for three factors: personalness, valence, and target. All possible interactions of these variables were also significant. Due to the many consistencies between the findings of these two studies and the many highly significant interactions, it was concluded that a multidimensional approach to the study of self-disclosure is both justified and required.
