Psychometric properties of the scale of self-protection skills from sexual abuse for students with mental disabilities integrated into the preparatory stage.

The current research aimed to verify the psychometric properties of the scale of self-protection skills from sexual abuse for students with mental disabilities integrated into the preparatory stage. The scale was applied to a sample of (30) students with mental disabilities integrated into the preparatory stage, whose chronological ages ranged from (13-16) years, with an average age of 76.14 years, and a standard deviation of 54.3. The research results the percentage of agreement of the arbitrators onranged between (80-100%), and the discriminant validity of the scale was calculated, as the difference between the highest quartile and the lowest quartile was statistically significant at the level of (0.01) and in the direction of the highest quartile level; which means that the scale has strong discriminant validity. The correlation coefficients between the dimensions and the total score ranged between (0.599 - 0.828), and the correlation coefficients between the score of each statement and the total score of the dimension to which it belongs ranged between (0.636 - 0.897), which are significant values at (0.01), indicating that the scale statements have an acceptable degree of consistency. The stability of the scale was verified in two ways, the first using the alpha stability coefficient, where the value of Cronbach's alpha coefficient for the scale dimensions ranged between (0.78 - 0.88), which are acceptable values. The stability was also calculated by the re-application method using the Spearman correlation coefficient, whose values ranged between (0.86 - 0.95), which are significant values at the (0.01)
