Reliability and validity of the Danish version of the Self-Assessment of Modes Questionnaire

Abstract

Background

The Self-Assessment of Modes Questionnaire (SAMQ) is developed to help therapists identify their preferred use of modes when interacting with clients in clinical practice. A Danish translation of the SAMQ has been developed (D-SAMQ). To provide a robust instrument for occupational therapy practice and research, evaluation of the psychometric properties of the D-SAMQ is needed.

Objectives

The study aims to evaluate test-retest reliability, measurement error and content validity in terms of cultural relevance of the D-SAMQ.

Material and methods

Danish occupational therapists were recruited to represent diverse clinical settings and to work with various age groups. The D-SAMQ consists of 20 clinical cases. A repeated measures design was employed with evaluation of content validity at the second timepoint. The Content Validity Index and Kappa statistics were employed.

Results

In most cases (n = 12, 60%) agreement (test–retest reliability and measurement error) was moderate or strong. Also, there was a moderate (n = 6 cases, 30%), strong (n = 4 cases, 20%) or almost perfect agreement (n = 10 cases, 50%) on the cultural relevance of the cases.

Conclusions

Acceptable test–retest reliability, measurement error and content validity were found. The SAMQ may support occupational therapists to adapt their therapeutic style to meet the needs of the clients.
