Construction and validation of a psychometric tool for generational identity

There is a lack of a psychometric tool
for generational identity. We have conducted two studies involving senior
Bangladeshi nationals, containing both independence war veterans and
non-veterans, to develop a new generational identity scale (GIS). The
first study (N=300) prepared an initial pool of 31 items and got them
vetted by expert judges, which retained 21 items to form the provisional GIS
(GIS-21). An exploratory factor analysis on GIS-21 excluded nine items and
offered a two-factor solution: (i)
identification with the generation and (ii) awareness of the generational
importance. The second study (N=176) ran a confirmatory factor analysis on
the resulting GIS-12 and dropped
another item to achieve a better model fit (χ2/df =74.74/42
=1.78, CFI =0.96, TLI =0.95, RMSEA =0.05, and SRMR
=0.05). The remaining 11-item GIS (GIS-11) showed excellent
reliability (mean inter-item correlation coefficient =.44, Cronbach’s alpha
=.89) and satisfactory temporal stability (ICC
=.61, 95% CI =0.30 to 0.78) over
a 4-week interval. The
Bangladesh independence war veterans scored higher on GIS-11 than did the
non-veterans, indicating the scale’s diagnostic validity. The scale’s moderate
correlation (rs=.63, p
