Monitoring session reactions in psychotherapy practice: Psychometric evaluation of the Session Reactions...

This study aimed to assess the psychometric properties of the Czech and Slovak versions of the brief version of the Session Reactions Scale-3 (SRS-3-B). The SRS-3-B was constructed to be used and interpreted primarily at the item level, but it yields scale and subscale scores as well. Therefore, psychometric analysis focused on both the item and scale levels.

Czech (N = 231) and Slovak (N = 235) samples were collected via an online survey. At the item level, item distributional properties, item redundancy, and construct and convergent validity were assessed. At the scale level, the factor structure, reliability, and convergent validity were assessed.

The items demonstrated reasonable response distribution, non-redundance, construct validity, and convergent validity at the item level. At the scale level, a two-factor solution was selected as the most meaningful and was invariant at the metric level across the Czech, Slovak, and English versions. The total scale and the subscales demonstrated reasonable reliability and convergent validity.

The Czech and Slovak versions of the SRS-3-B are valid process measures. They can be used to elicit rich and clinically meaningful feedback from clients within the context of measurement-based care.
