The Convergent Validity Between Two Adult Self-Report Sensory Processing Scales
None:
Background Occupational therapists use standardized scales to assess how individuals process and respond to sensory information. Currently, there is limited evidence about the convergent validity between the Adult/Adolescent Sensory History (ASH) and the Sensory Processing Measure 2-Adult Form (SPM-2-Adult). Purpose. The study examined the convergent validity of the ASH and SPM-2-Adult when completed by young adults. Method. Fifty Australian adults aged 21-35 completed the ASH and SPM-2-Adult. Spearman's rho correlations were used to analyze the data. Results. Most ASH and SPM-2-Adult subscales were significantly associated with correlations ranging from rho = 0.301 to 0.858 (p < .033-.001). Statistically significant correlations were obtained between the SPM-2-Adult Vision subscale and every ASH subscale (rho = 0.322-0.841, p < .023-.001) while the SPM-2-Adult Taste and Smell subscale yielded the most non-significant correlations with the ASH. Most of the statistically significant correlations between the ASH and SPM-2-Adult were in the moderate range. Conclusion. Promising evidence of convergent validity between the ASH and SPM-2-Adult sensory subscales and total scales was demonstrated, whereas the convergent validity findings between the ASH Functional-Problems subscales and the SPM-2-Adult sensory subscales were less robust. This adds to the psychometric body of concurrent validity evidence between the two scales.

Sensory Modalities
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
