“…Further, those in the bereaved sample were either native English speakers or highly competent in English, meaning that the experiences of people from culturally and linguistically diverse backgrounds might not be represented adequately in the data. Samples of other research projects on the psychosocial outcomes of crash fatalities have been drawn either from activist groups (e.g., Federation of European Road Traffic Victims, 1993Victims, , 1995Lord, 1987;Tehrani, 2004), or mutual-help groups (e.g., Spooren et al, 2000Spooren et al, -2001Sprang & McNeil, 1998), or the wider community (e.g., Lehman et al, 1989;Shanfield & Swain, 1984). Sampling from four sources (a mutual-help group, an activist group, community newspapers, and snowballing from informants) reduced the likelihood that the sample, and therefore the data, is prejudiced, and thus confidence in a relatively representative sample is high.…”
