The study was to verify the validity and reliability of the Self Scaling on Stuttering Situations (SOS).
Participants included 20 adults who stutter (AWS) and 20 adults who don’t stutter (AWNS). They completed the SOS and the Subjective screening of stuttering severity, locus of control and avoidance, Revised edition (SSS-R). The validity (i.e., content, construct, and concurrent validities), the internal consistency reliability (i.e., Cronbach’s alpha and test-retest reliability), and the item discrimination tests were measured.
The SOS showed high validity and reliability as follows, 1) the mean content validity of the SOS was 4.43 (SD = 0.28), 2) the correlation coefficients between the total score and the scores of the three sections (construct validity) were 0.672-0.925, 3) the correlation coefficients between the SOS and the SSS-R (concurrent validity) were 0.665-0.825 except the frequency of the SOS, 4) the Cronbach’s alpha values of the three sections were 0.905-0.965, 5) the test-retest reliability values using the Pearson correlation analysis were 0.821-0.958, 6) the item discrimination to test between AWS and AWNS indicates that no significant difference was found in the frequency of occurrence, however significant differences were found in the 14 items of the Avoidance and 23 items of the stuttering severity.
The results showed that the SOS could be a valid and reliable instrument to evaluate AWS more comprehensively on 23 situations. SOS may be used as a tool to establish treatment goals of fluency disorders in various situations.
Key Words: Subjective screening of stuttering, Situations, Stuttering severity, Avoidance, Validity and reliability.
