“…Similar to previous studies (e.g., Mullen, 2001;Mullen et al, 2000Mullen et al, , 2001Mullen & Johnson, 1993, 1995Mullen & Rice, 2003), the present analyses were based on a sample of 19 European ethnic groups (Belgian, Dutch, English, French, German, Greek, Hungarian, Irish, Italian, Norwegian, Polish, Portuguese, Russian, Scots, Spanish, Swedish, Swiss, Turkish, and Welsh). It should be emphasized that the 19 European ethnic groups under consideration in this line of research accounted for 80% to 90% of all immigrants into the United States during the time periods under consideration.…”
