Summary
1 There is evidence that mobiles and landlines access different populations
simply in terms of consent for participation in sex-related research
2 There is evidence that mobile and landline samples differ with respect to the
extent of reported same-sex contact but only for women – not men
3 There is evidence that mobile and landline samples differ with respect to the
extent of reported opposite-sex contact but the differences appear to be
more extreme for women than for men
