Construct validity of the Schwartz Outcome Scale: validation using a 28-day inpatient chemical rehabilitation patient sample.

The Schwartz Outcome Scale-10 (SOS-10) is a 10-item self-report that measures quality of life and psychological well-being. It is easy to administer and score, and past research has revealed its utility, validity, and reliability with different samples (i.e., clinical and nonclinical) and in different clinical settings (i.e., inpatient, outpatient, nonpsychiatry medical settings). The present study looks to investigate the utility of the SOS-10 in measuring psychological well-being and quality of life with the 28-day inpatient chemical dependency sample. In addition, the current study looks to investigate its ability to be used as a treatment outcome measure for chemical-dependent inpatients. The results revealed that the SOS-10 was associated with aspects of interpersonal dependency and alexithymia in predicted ways. The SOS-10 was positively associated to "Healthy Dependence" and negatively related to alexithymia and "Destructive Overdependence" and "Dysfunctional Detachment." The results also showed that the SOS-10 showed healthy change from admission to discharge and that this change was paralleled by healthy change in interpersonal dependency and alexithymia.
