Scaling of items
Agree, disagree, or not sure
Total scale score based on number of subject agreements with specific responses to individual items (possible range for LSI-A with one point given for each agreement: 0-20; possible range for LSI-Z with 2 points given for each agreement: 0-26)
Content validity assured by items based on repeated interviews with people aged 50 - 90 years about life pattern, attitudes, values, daily activities, social interaction, and other concerns.
Construct validity demonstrated through correlations between LSI-A and a Life Satisfaction Rating and between LSI-Z and a Life Satisfaction Rating. Factor analysis of the LSI-A produced 4 factors, of which 3 were interpretable: mood tone; zest for life; and congruence.
