Development and preliminary validation of the C‐SCORE: A brief scale for use in systemic couple therapy

Abstract A new version of the Systemic Clinical Outcome Routine Evaluation (C‐SCORE) was developed for use with couples to assess, plan and monitor progress in therapy. This study aimed to examine the psychometric properties of C‐SCORE in an international community sample of 300 participants. Exploratory and confirmatory factor analysis showed that a twenty‐two‐item, five‐factor version of C‐SCORE best fit the data. The scale and its factor sub‐scales had good internal consistency and test–retest reliability over a 1‐month period. C‐SCORE showed good concurrent and construct validity as evidenced by significant associations with other measures of couple relational functioning, mental health and wellbeing and self‐rated couple issues. These promising findings require further validation with a clinical sample.
