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 purpose of this study was to examine the clothing practices in the daily selection, care, and purchase of clothing by adolescents in order to determine the extent these practices are performed independently or influenced by others, and to identify the factors involved in the activities. Clothing Practice Profiles were developed for both sexes in the three age groups corresponding to divisions in the Oregon 4-H program. The age group comparison revealed increasing frequency of independent activity in all three clothing practice areas (selection, care, and purchase) as age increased. Parental influence appeared to decrease with increasing age. Siblings' influence was minimal. Peer influence on selection and purchase practices increased. Media influence on daily clothing selection practices and clothing purchase practices in terms of wearing or buying identical or similar clothing was minimal. Media influence in advertisements increased with age, but purchases of advertised clothing items remained about the same. Age group comparisons were also made for selection factors and other care and purchase practices, including responsibilities for care of the member's and family's clothing, planning clothing purchases, sources of funds and methods of paying for clothing, use of clothing label information, and purchase factors.  相似文献

Data for the presenting complaints, average age and sex distribution, average length of stay and the discharge diagnosis for 900 consecutive adolescents treated at the Adolescent Center of Houston International Hospital between 1974 and 1982 were reviewed. The number of cases remained fairly constant over the 9 years. As the males and females showed an increase in age, the increase in age for males (13.4 years to 15.2 years) was greater than that for females (14.4 years to 15.0 years). The average age for male admissions during 1974-1976 was significantly lower than 1980-1982 (p less than 0.03). The average length of stay for males during 1980-1982 was significantly greater than 1974-1976 (p less than 0.05). The most frequent presenting symptoms in decreasing order for 1974-1982 were depression, school problems, family problems, threatening behavior, runaway behavior, and suicidal ideation. Depression increased from 15.6% in 1974-1976 to 29.6% of presenting symptoms. Substance abuse increased from 4% (1974-1976) to 8.8% (1980-1982). Suicidal ideation increased three-fold over the same period (3.3% to 10.6%). A significantly greater number of males presented with 1) impulsivity, 2) aggressiveness, 3) withdrawal behavior, 4) stealing, and 5) disruptive behavior. A significantly greater number of females presented with 1) runaway behavior, and 2) suicidal ideation. The 10 most frequent discharge diagnoses are listed. Depression as a diagnosis increased almost four-fold between 1977-1979 and 1980-1982 (7.6% versus 27.5%).  相似文献

This study compared the symptomatology and diagnoses of adopted and nonadopted adolescents in a psychiatric hospital. Data were gathered from the hospital charts of adolescents who already had been discharged from the hospital. Contrary to expectations, adoptees were no more likely than nonadoptees to have received personality disorder diagnoses, nor were they more likely to be hospitalized as the result of antisocial behavior. However, in comparison with nonadopted adolescents, the adopted adolescents were younger upon admission to the hospital, significantly less often diagnosed psychotic, and significantly more often diagnosed adjustment reaction. It was suggested that adopted adolescents may be less likely than nonadopted adolescents to require severe or prolonged pathology in order to be admitted to a psychiatric hospital. It was also suggested that the antisocial symptomatology so frequently observed in adopted children in mental health settings does not account for the hospitalizations of those receiving inpatient treatment.  相似文献

Some of the common conflicts that occur between therapists and direct-care staff in residential, adolescent treatment facilities are highlighted. These conflicts often parallel those occurring between an adolescent's parents. Common issues include the amount of time spent with the adolescent patient, questions of authority, and communication difficulties. These conflicts can have positive consequences, if each party recognizes that the other brings a needed perspective to adolescent treatment.  相似文献

In a recent article on mood-induction procedures, Clark (1983) concluded that the Velten Mood Induction Procedure (VMIP; Velten, 1968) produces a good analog state of mild, naturally occurring, retarded depression that is not explicable in terms of experimental demand characteristics. Clark concluded, however, that it is erroneous to view the relative success of the VMIP in simulating the effects of depression as support for cognitive theories of depression. While we agree with the first of Clark's conclusions, we disagree with his second conclusion that the VMIP is not a cognitive manipulation. The purpose of the present article is to argue that his ideas regarding the impact of the VMIP on mood and behavior are not supported by the existing data. Therefore, the VMIP results can be used to support Beck's (1976) cognitive theory of depression.  相似文献
