Guided by Alberts, Tracy and Trethewey's (2011) integrated theory of the division of domestic labor, this dissertation examined the influence of domestic labor response threshold (i.e., the point at which one is sufficiently disturbed by a task undone so as to feel compelled to attend to it) on domestic labor performance and domestic labor conflict. Three-hundred-ten heterosexual participants (155 marital dyads; average marriage length of 20 years) completed an online questionnaire about their performance of household labor, household labor conflict, and response thresholds. Response thresholds were assessed using traditional verbal measures as well as two visual (i.e., photographic) measures developed for this investigation. The data were analyzed using three methods of dyadic data analysis: structural equation modeling, repeated measures multivariate analysis of variance (MANOVA), and actor-partner interdependence models using multilevel modeling. Results indicate that the lower one's response threshold, and the higher one's partner's response threshold, the greater one's contributions to household tasks. Additionally, the lower one's response threshold, and the higher one's partner's response thresholds, the more likely the demand-withdrawal pattern is to emerge in domestic labor conflicts. Finally, mutual avoidance is more likely when one partner perceives that it is less costly to complete domestic work than to engage in conflict about it, or when one partner perceives that domestic labor is not a worthwhile or appropriate conflict topic. Contributions of this investigation include support for the integrated theory of the division of domestic labor, increased understanding of how individual differences (working in concert with actor sex) contribute to domestic labor allocation and conflict, a more sensitive measure of response threshold, and preliminary evidence of the "logics" of avoidance of domestic labor conflict.
