There was a significant reduction in ISADL one month after
trauma. The ISADL score improved three months after
trauma, but it did not reach to its preinjury period (Table
2). Two-way ANOVA showed a significant association between
the scores of ISADL, time interval and type and location
of an injured organ, and the undergoing surgery
as a treatment (Table 3). Other variables including gender,
education, and marital status had no significant effect.
In multiple regression analyses, age and marital status
could explain 67.1% of independence in ISADL before trauma.
One month after trauma, gender, age, occupation,
education, cause of trauma, location of an injured organ
and having surgery for treatment made a model with independence
in ISADL. All these variables could explain
72.6% of ISADL score. Three months after injury only age,
having surgery and kind of treatment showed significant
associations with ISADL and could explain 69.1% of this
variable (Table 4).
