Construct Validity of the Schwartz Outcome Scale

Abstract

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.

Construct Validity of the Relationship Profile Test: Links With Measures of Psychopathology and Adult Attachment

“…These results replicate and extend existing research (Bornstein et al, 2010; Haggerty et al, 2012). DO was broadly positively associated with increased psychopathology, whereas HD showed the opposite pattern.…”

“…DD was not significantly correlated with many of the scales of the PAI, and showed smaller magnitude correlations with the SCL-90-R scales than did DO. This latter result was unexpected and could be related to DD’s lower internal reliability; however, when the internal consistency reliabilities of this study are compared to the past 12 RPT studies reporting Cronbach’s alpha values, internal consistency reliability, (Bornstein et al, 2003; Bornstein et al, 2004; Bornstein et al, 2009; Bornstein et al, 2010; Denkle et al, 2011; Denkle et al, 2015; Haggerty et al, 2010; Haggerty et al, 2012; Huprich et al, 2010; Hutchins & Raith, 2014; Porcerelli et al, 2009; Porcerelli et al, 2015) the present values are not much different from previously reported reliabilities (average Cronbach alphas for DO, DD and HD for these 12 studies are .82, .72, .74 respectively).…”

“…We compared RPT scores to scores on two well-validated and widely used broadband measures of psychopathology, the Personality Assessment Inventory (Morey, 1991) and the Symptom Checklist-90-Revised (Derogatis, 1994) as well as a short-form of the Experiences in Close Relationships Scale (Wei, Russell, Mallinckrodt, & Vogel, 2007), a dimensional measure of adult attachment. Past research on the construct validity of the RPT found that the Destructive Overdependence (DO) and Dysfunctional Detachment (DD) scales were negatively correlated with measures of psychological health and attachment security, and positively correlated with measures of psychopathology and attachment insecurity (Bornstein & Huprich, 2006; Bornstein, Porcerelli, Huprich, & Markova, 2009; Haggerty et al, 2010, 2012; Huprich, Hsiao, Porcerelli, Bornstein, & Markova, 2010). The present study seeks to extend these results using different measures, and in a different population—patients with substance use disorders.…”

Psychometric Properties of the Farsi Version of the Schwartz Outcome Scale

“…Internal consistency coefficient of the SOS-10 was acceptable and compared well with the original English version reported by Blais et al, demonstrating a high internal consistency (11,19,31). Furthermore, the scale's testretest reliability among the 50 selected non-patients over one week indicated significant reliability, and the results were consistent with those of the original and other validation and adaptation studies (12,13,17).…”

“…The validity of this scale was measured by using many other psychological measures. Overall, the results show that SOS-10 is a valid and reliable scale for adults and adolescents (10,11,19,30,31).…”
