Dyadic Adjustment Scale (DAS; Spanier, 1976)
The DAS is a widely used 32-item measure of global relationship quality. The summed total score, which ranges from 0 to 151 (higher scores reflect better functioning), was used to characterize global relationship functioning. Alpha was .90 for the total sample (.91 wives, .89 husbands).
All standard deviations reported below and in Table 1 for the diary measures represent within-subject variation, not a combination of variation over days and participants. The reliability of these scales represents within-person consistency (reliability of change; Cranford et al., 2006). See Table 1 for means, standard deviations, and reliabilities and Table 2 for intercorrelations between daily measures.
