The article presents a study dealing with the perceived effects of voluntarism on marital life in late adulthood among a sample of 595 Israelis (336 men and 259 women). These perceptions were examined from three perspectives: benefits, spousal accommodation, and harmful effects. Comparisons focused on different types of families, based on employment status (pre-retired versus retired) and actual volunteer activity (volunteer versus non-volunteer). The findings revealed that among all types of families, the prevailing tendency was to emphasize the beneficial effects of voluntarism on marital life, whereas perceived harmful effects were least prevalent. Synchronous families (both partners pre-retired) and asynchronous families (pre-retired participant / retired spouse) emphasized the need for spousal accommodation to marital life more than the other two types of families. In addition, men were found to emphasize the need for spousal accommodation more than do women. In asynchronous families (one partner pre-retired and the other retired), women showed a greater tendency than men to mention the harmful effects of voluntarism for the marital relationship. Congruent families (where both partners volunteer) showed a greater tendency to perceive voluntarism as having a beneficial effect on marital life than did other types of families.
