Index of Social Interaction
Description of Measures
Purpose
To measure the social interaction.
Objects
ISI is appropriate for the assessment of social interactions over twelve years old.
Conceptual Organization
ISI was developed for evaluating social interactions of various types and includes 18 items. Factor analysis revealed 5 subscales: 1) Independence, which includes having a motivation to live an active lifestyle, taking an active approach towards one’s life, being motivated to live a healthy life, and having a regular or routine lifestyle; 2) Social curiosity, which comprised reading newspapers, reading books, trying to use new equipment, having a hobby, and having a feeling of importance; 3) Interaction, composed of communication within the family, communication with non-family persons, and interactions with non-family persons; 4) Participation in society, made up of participation in social groups, participation in neighborhood affairs, watching television and having an active role in society; and 5) Feelings of safety, meaning having counsel, and having someone to give support in an emergency (see Table 1).
Materials
Non-copyrighted TCS (Tobishima Cohort Study) version of the form is included in this manual
Time Required
Less than five minutes
Scoring
Score Types
Each item’s score was rated one point for a positive response (yes, I do this or yes, I have this) and zero for a negative response. Thus, both subscale scores and the total ISI score were calculated simply by summing the positive responses. For missing data, the mean score of the rest of the items was used to replace the missing score.
Score Interpretation
Higher scores reflect higher level of social interaction.
Psychometric Support
Reliability and Validity
The Index of Social Interaction (ISI) was tested on 1,064 community dwelling elderly in Japan and it show highly significant correlations with future health decline and dementia.
Cronbach’s alpha for the subscales ranged from .78-.81 (Anme, 2007).
