“…Many of the advances in measurement occurred during the past two decades (e.g., Norton, 1983;Roach, Frazier, & Bowden, 1981;Sabatelli, 1984;Schumm, Nichols, Schectman, & Grigsby, 1-983;Snyder, 1979;Spanier, 1976). Also during this period, research models have been expanded to include a greater diversity ofindependent variables, including such individual characteristics as sex-role orientation and personality traits (Bowen, 1-989;Bowen & Orthner, 1983;Davidson & Sollie, 1987;Li & Caldwell, 1987;Schonnesson, 1987), relationship variables such as commirmenr (Scanzoni & Arnett, 1987;Swanson & Trahaug, 1985), and leisure activity (Holman & Jacquart, 1988). Most of these researchers have been interested in identifying correlates which may explain more of the variation in marital quality and satisfaction.…”
