This information was gathered with the SSNF for persons in each of the following categories:
The definition of "friend" provided to the interviewees was a person a student considered to be "socially important" and somebody they "liked." Psychometric characteristics of the SSNF were studied previously (Kennedy, 1991) and the instrument was found to have a test/retest reliability of 90% (mean percent agreement) and a congruent validity for social contact validity as indexed against a direct observation measure (i.e., the SCAF of r  = .87p [is less than] .01).
Data collection using the SCAF and SSNF began in October 1994 and continued until May 1995.
During 39%, 46%, and 15% of SCAF, SIC, and SSNF sessions, respectively, interobserver agreement (IOA) was assessed.
Two sources of information were used to assess the occurrence of social support behaviors -- direct observations (SIC) and interviews (SSNF).
Table 4 shows a second set of the outcomes for social support behaviors and are arrayed as the percentage of people listed on the SSNF who engaged in at least one instance of a particular social support behavior during the previous 2 weeks.
Data from the SSNF were used to assess and compare students' friendship networks and the duration of social relationships.
