Construct validity of the Schwartz outcome scale‐10: comparisons to interpersonal distress, adult attachment, alexithymia, the five‐factor model, romantic relationship length and ratings of childhood memories

Abstract

The Schwartz Outcome Scale-10 (SOS-10) is a 10-item questionnaire that measures the broad domain of psychological well-being and quality of life. The SOS-10 is easy to administer and score. Past research has shown its utility, reliability and validity in different clinical settings (i.e., inpatient, outpatient and non-psychiatry medical settings) and with diverse clinical populations in measuring treatment outcome. The present study looks to extend the construct validity of the SOS-10 to assessing quality of life and psychological health in non-clinical samples as well. The results reveal that the SOS-10 is associated in predicted ways with established measures of attachment, interpersonal distress, alexithymia and the big five model whose construct validity and psychometric soundness has been well documented. The SOS-10 was also associated in predicted ways with ratings of childhood memories and the length of the participants' longest romantic relationship.

Determining adolescents' suitability for inpatient psychotherapy: Utility of the clinician-rated Readiness for Inpatient Psychotherapy Scale with an adolescent inpatient sample

“…Higher scores on the SOS-10 are representative of better psychological health and well-being. Research has shown that the SOS-10 is a valid and reliable measure of quality of life and psychological well-being with adults and adolescents (Dragomirecka, Lenderking, Motlova, Goppoldova, & Selepova, 2006;Haggerty, Blake, Naraine, Siefert, & Blais, 2010Laux & Ahern, 2003;Rivas-Vazquez et al, 2001;Young, Waehler, Laux, McDaniel, & Hilsenroth, 2003). Cronbach's alpha in the present study was .92.…”

Construct Validity of the Schwartz Outcome Scale

“…We proposed several hypotheses from the research on alexithymia (Grabe et al, 2008;Haggerty et al, 2010a;Lumley et al, 2007) and interpersonal dependency (Haggerty et al, 2010b). SOS-10 total scores were expected to be negatively associated with alexithymia and several aspects of interpersonal dependency (i.e., DO and DD).…”

“…The measure has been translated into Spanish (RivasVazquez et al, 2001) and Czech (Dragomirecka et al, 2006) and has demonstrated good psychometric properties. The utility of the measure has been extended outside of the psychiatry population to more normative samples including college undergraduates (Haggerty et al, 2010a;Young et al, 2003).…”

Early psychotherapeutic empathy, alliance, and client outcome: Preliminary evidence of indirect effects

“…Each item features a 7‐point scale ranging from “0 – never” to “6 – nearly all of the time.” Sample items include “I have confidence in my ability to sustain important relationships” and “I am generally satisfied with my psychological health.” The SOS‐10 is scored by summing the 10 items (higher scores indicate better well‐being). This measure has demonstrated good internal consistency, test‐retest reliability, and convergent/discriminant validity (Haggerty, Blake, Naraine, Siefert, & Blais, ; Young, Waehler, Laux, McDaniel, & Hilsenroth, ). The SOS‐10 exhibited high internal consistency in the present research (Cronbach α = 0.84 at pretreatment).…”
