Differentiating specialists and generalists within college students' social support networks 总被引:1,自引:0,他引:1
G. Anne Bogat Robert A. Caldwell Fred A. Rogosch Julie Ann Kriegler 《Journal of youth and adolescence》1985,14(1):23-35
In order to examine the relationships among social network structure, types of social support, and determinants of support satisfaction, an alternative method was used to score the Social Support Questionnaire (SSQ). Factor analysis procedures suggested that college students' (N=198) social networks consisted of four groups: nuclear family, other family, friends, and others. Satisfaction with support was positively related to the proportion of the network occupied by nuclear family and negatively related to the proportion of friends in the network. Evidence was found for the presence of both support specialists and support generalists in the networks of the college students. These results are discussed from a developmental perspective with attention to the implications for interventions. 相似文献

Murder-suicide in New Hampshire, 1995-2000 总被引:1,自引:0,他引:1
Combined murder-suicide is defined as homicide(s) followed by the perpetrator's suicide within 1 week of the homicide(s). This phenomenon is observed worldwide with generally similar incidence rates. The authors report data from New Hampshire, a population distinguished from those in previous United States studies by its location, racial homogeneity, nonurban character, and low homicide rate. Sixteen murder-suicide events occurred in New Hampshire between October 1995 and October 2000. This represents an incidence of 0.26 per 100000 person-years, a rate similar to previously reported values. Murder-suicide events accounted for 14.7% of all homicides in the state, higher than previous studies but not unexpected in view of the state's lower homicide rate. Most perpetrators were male (94%), and most victims were female (88%), often in a spousal or consortial relationship. Firearms accounted for the majority of deaths. Various cofactors are examined, and a comparison of two recently proposed classification systems is discussed. 相似文献
