The results from the first survey were widely used by academics and policymakers. Towards the end of the 1990s, it became increasingly clear that the NATSAL I results were growing outdated and that repeat measures were needed not only to provide up-to-date information for estimating the likely extent of the HIV epidemic in Britain, but also to look at behaviour change over time and to include new questions to take account of current information needs in the field of sexual health.<br> <br> The main objectives of NATSAL II were to:<ul><li>provide a detailed understanding of patterns of sexual behaviour in Britain (including for example, numbers of sexual partners, frequency of different sexual practices, and homosexual experience)</li><li>provide data for HIV/AIDS projections in Britain</li><li>assess whether there have been changes in behaviour since NATSAL I</li><li>measure the prevalence of <i>chlamydia trachomatis</i> infection, via urine samples</li></ul>Given the importance of making comparisons with NATSAL I data, NATSAL II was largely a repeat of the 1990 survey. However, it was also recognised that a number of methodological developments in survey research in the intervening period could lead to improvements in the data collection process for NATSAL II. In particular, the use of Computer Assisted Personal Interview (CAPI) and Computer Assisted Self-Interview (CASI) techniques had the potential to improve on response rates and data quality, as well as maximise the disclosure of sensitive behaviours.<br> <br> Along with the changes in methodology, there were a number of other differences between NATSAL I and II:<ul><li>NATSAL II covered a younger age group (ages 16-44) than NATSAL I (16-59) in order to focus survey resources on a group greater at risk</li><li>people living in the Greater London area were purposely over-sampled</li><li>a boost sample of people from four ethnic minority groups - Black Caribbean, Black African, Indian and Pakistani - was included</li><li>new question modules were introduced on, for example, partnership formation, sexual mixing abroad, preferred sources of contraception and advice, history of sexually transmitted infections, and sexual dysfunction</li><li>a urine specimen was collected from consenting respondents, to test for <i>chlamydia trachomatis</i></li></ul><br></h5><h3>Main Topics:</h3><h5>The face-to-face interview included sections on: general health, family, learning about sex, first sexual experience, contraception, attitudes, and household classification. <br> <br> The self-completion questionnaire included sections on: sexual attraction and experience, heterosexual sex, homosexual sex, number of partners, sex abroad, most recent partners, paying for sex (males only), miscarriage, sexually transmitted diseases, HIV/AIDS testing, sexual problems.</h5> <h3>Coverage: </h3><h5> <br><i class='myclass'>Dates of Fieldwork: </i> May 1999 - August 2001 <br><i class='myclass'>Country: </i> Great Britain <br><i class='myclass'>Spatial Units: </i> Government Office Regions (GORs); Standard Regions <br><i class='myclass'>Observation Units: </i> Individuals <br><i class='myclass'>Kind of Data: </i> Numeric data; Individual (micro) level </h5> <h3>Universe Sampled: </h3><h5> <i class='myclass'>Location of Units of Observation:</i> National <br><i class='myclass'>Population:</i> Men and women aged 16-44 living in private households in Great Britain in 2000-2001. </h5> <h3>Methodology: </h3><h5> <i class='myclass'>Time Dimensions: </i> Repeated cross-sectional study<br> Second wave: the first survey was conducted in 1990-1991. <br><i class='myclass'>Sampling Procedures: </i> Multi-stage stratified random sample <br><i class='myclass'>Number of Units:</i> 12,110 cases <br><i class='myclass'>Method of Data Collection: </i> Face-to-face interview; Self-completion; Clinical measurements <br><i class='myclass'>Weighting: </i> Weighting used.
