This study concerns the manner in which the traumatic events suffered by the parent in the Nazi holocaust are communicated to the second generation born after the Second World War. Additionally we investigated the effects of differences in wartime experiences on subsequent communication behaviors. Communication behaviors in families whose parents had been prisoners in concentration camps were compared with those of families who had displayed active resistance (i.e., were partisans) during the Second World War. The data indicate greater legitimacy and openness in discussing holocaust-related issues in the homes of ex-partisans than in the homes of ex-prisoners in concentration camps. Also, sons and daughters of the former group have better knowledge of the holocaust and hold more favorable attitudes than do sons and daughters in the second group. The implications of these findings are discussed. 相似文献

The work of the Center for the Study of the Family in Milan has had wide influence. We describe its influence on us--the positive connotation of many car journeys, our self-training, and changes in how we view, and function in, our personal and professional lives. 相似文献

Suicidal thoughts and their relationship to family stress and personal problems among high school seniors and college undergraduates 总被引:2,自引:0,他引:2
L S Wright 《Adolescence》1985,20(79):575-580
This study investigated the incidence of serious suicidal thoughts (ST's) among 207 high school seniors and 901 college students, and the relationship between ST's and family stress, drinking and drug-abuse problems, and delinquency in these groups. Over 10% of the high school and over 6% of the college students reported ST's. Those considering suicide attempts in both groups were more likely than their classmates to view their parents as having many conflicts with each other, to think of their relationship with their father as poor, to see at least one of their parents as either angry or depressed much of the time, and to perceive themselves as having a drinking or drug-abuse problem. These findings support the call for comprehensive counseling programs at both the high school and college levels. 相似文献
