Objective: The Australian Therapy Outcome Measures for Occupational Therapy (AusTOMs-OT) are used internationally to measure the outcomes of occupational therapy services across diagnoses, ages, and health care settings. This study reports on the inter-rater and test-retest reliability of the Self-care and Transfer scales as well as the intra-rater reliability of all scales of the Swedish (AusTOMs-OT-S) translation. Methods: Fifteen occupational therapists rated 11 case study clients on two occasions, separated by two weeks. Test-retest reliability and inter-rater reliability were calculated for the Self-care scale and Transfer scales. Moreover, intra-rater reliability was calculated for each of the 15 therapists across all 12 scales. Results: The inter-rater reliability intraclass correlation coefficients (ICCs) were all found to be high to very high, ranging from ICC 0.762 to 0.904; the intra-rater reliability coefficients were also very good with 11 of the 15 therapists achieving ICCs of 0.745 or over, and finally the test-retest ICCs were also found to be high, ranging from 0.705 to 0.920. Conclusions: Although further research is required to confirm reliability, preliminary reliability of the AusTOMs-OT Swedish translation has been demonstrated and therapists can have confidence when using the scales.
