Men who have sex with menArchived
In Europe, behavioural surveillance in MSM is mainly based on convenience samples of this population. Selected features of available methods for collecting behavioural data for surveillance among MSM are presented in the Table 1 below.
The second table presents the best three methods proposed by the experts according to two different contexts.

Design | Advantages | Disadvantages | Comments |
---|---|---|---|
"Convenience samples", non-representative designs |

Venue-based surveys (a) |
|
Not representative of the whole target population, although there is information on the bias. |

Internet surveys (b) |

The second table presents the best three methods proposed by the experts according to two different contexts:
- the population is reachable in known settings and is not severely stigmatised
- the population is not very well known, not easy to reach, and/or stigmatised
