Two approaches. Life-table and Laing cross-sectional calendar approach were applied to two sets of data, the Determinants and Consequences of Contraceptive Use Pattern in Thailand (CUPS) and the 1987 Thailand Demographic and Health Survey (TDHS). Both surveys were taken in the year 1987. The results show that the contraceptive use calendar in CUPS yields slightly lower continuation rates and slightly higher failure rates compared to the results from TDHS. However, the differences in estimated continuation and failure rates are small enough to conclude that either method of data collection can be used to provide those basic rates. The estimated rates for cross-section approach were reliable when the period of observation is two years or more. TDHS type data collection provide reasonable estimates of the rates with moderate effort in data collection. Calendar data is probably more difficult to collect. However, if interview training and data collection are not big obstacles, the calendar method is recommended for more accurate data collection. Furthermore, it is found that among temporary methods IUD was the most acceptable contraceptive method in every period of observation. The second method was pills, followed by injections, withdrawal, rhythm and the least was condom. However, the most effective method was injections while pills and IUD were about the dame level. The least effective methods were withdrawal and rhythm while condom had moderate effectiveness.
