調查方法
| 有關主權回歸後整體環境變化的調查是由九七年七月一日起計，大約在25、 50、75、100、200、300、500、600、及1000日後進行，採用先密後疏策略。每 次調查皆屬嚴格督導下的訪員進行的親身電話問卷訪問。 | ||
| 所有調查的訪問對象皆為十八歲或以上之操粵語的香港市民。 | ||
| 電話號碼抽樣方法是從住宅電話簿中首先以隨機方法抽取「種籽」號碼，再 以加一減一加二減二的方法產生另一組號碼，然後在混合後再過濾重覆號碼 ，再以隨機排列方式排次成為最後樣本。 | ||
| 抽取住戶成員的方法是由訪員在成功接觸目標住戶後，用「即將出生日期」 的方法由當時在家的成員抽取其中一人進行訪問。 | ||
Survey Method
 | Surveys on people's assessment of the overall condition are conducted around the 25th, 50th, 75th, 100th, 200th, 300th, 500th, 600th, and 1000th day after the handover day of July 1, 1997. The intervals between these surveys thin out gradually. All surveys are conducted by telephone interviewers under close supervision. | ||
| Target population of these surveys are Cantonese speakers in Hong Kong of age 18 or above. | ||
| Telephone numbers are first selected randomly from telephone directories as seed numbers. Another set of numbers is then generated by using the plus/minus one/two method. Duplicate numbers are then screened out, and the remaining numbers mixed in a random order to become the final sample. | ||
| Upon successful contact being made with a target household, one member of the household is selected among those present using the "next birthday" rule. | ||
