The Sensory Processing Measure, Second Edition, Adolescent Self-Report Form; Swedish Translation, Cross-Cultural Adaptation, and Establishment of Reliability and Face Validity

The Sensory Processing Measure, second edition (SPM-2), is an American assessment guiding person-centered sensory processing interventions, but it lacks Swedish adaptation for occupational therapists. In eight phases, this study translated the SPM-2 into Swedish and assessed its face validity and preliminary psychometric properties, including internal consistency and inter-scale/item correlations. The findings suggest the Swedish SPM-2 is valid and reliable, although the Social Participation scale showed weak internal consistency. A larger normative study (N = 130) is needed before clinical use.
