The National Family Research of Japan {NFRJ} 2008-2012 Panel Study {NFRJ-08Panel} project finished its scheduled surveys after completing Wave 5 in February-March in 2013. The official report {NCID:BB15480829} has been published by the NFRJ Committee. In this paper, we review and evaluate the survey responses for the NFRJ-08Panel Waves 1-5.
I. The number of responses for each wave of the NFRJ-08Panel: Valid responses amounted to 1,622 for Wave 2 (2010), 1,555 for Wave 3 (2011), 1,515 for Wave 4 (2012), and 1,594 for Wave 5 (2013). Even for the Wave 4 with the fewest responses, we obtained more than 1,500 valid responses.
II. Detailed patterns of responses and valid response rates among waves: 1,317 returned valid responses for all waves. 217 returned three valid responses, 123 returned two, 121 returned one, and 101 returned no valid response for the four surveys of Waves 2-5. When we conducted {NFRJ08} (in 2009) for the sample of 9,400 people, there were 4,197 nonresponses for the NFRJ08 survey and 3,324 refusals to participate in the following panel surveys. Waves 2-5 (in 2010-2013) yielded 1,515 to 1,622 valid responses, indicating that withdrawals ranged from 257 to 364. 14.0% of the sampled 9400 people responded to the all five waves.
III. Methods of distribution and collection of questionnaires for Waves 1 and 5: Among all the valid responses for {NFRJ08}, 87.4% were handed an unsealed questionnaire to the canvasser, 11.0% were sealed in an envelope, and 1.6% were returned by mail (NFRJ08 1st report {NCID:BB02272294} p. 36). Among those who returned one or more valid response for Waves 2-5, 91.0% of the Wave 1 responses were retrieved in an unsealed questionnaire, a higher rate than for the whole pool of NFRJ-08 respondents, with an accordingly lower rate of collection with sealed envelope. These figures suggest that NFRJ08 respondents tended not to participate in our panel study, if they felt that handing an unsealed questionnaire to the canvasser compromised their privacy.
