Factor Structure and Construct Validity of Children Participation Assessment Scale in Activities Outside of School-Parent Version (CPAS-P).

The aim of this study was assess the factor structure, reliability and construct validity of the Children Participation Assessment Scale in Activities Outside of School-Parent Version (CPAS-P). The participants of this study were 700 parents of children aged 6-12 years. For data analysis, the confirmatory factor analysis, internal consistency, and test-retest reliability were conducted. Convergent validity was calculated by correlation with the Vineland Adaptive Behaviour Scale. The results indicated the CPAS-P has good internal reliability. Overall, Cronbach's alpha for the participation measures ranged between 0.87 and 0.91, indicating good homogeneity, and Spearman correlations for convergent validity was acceptable. The temporal stability of the CPAS-P was supported with Intra-Class Correlations ranging from 0.79 to 0.94. Therefore, the CPAS-P, which evaluates all eight areas of occupation (i.e., activities of daily living, instrumental activities of daily living, play, leisure, social participation, education, work, and sleep/rest) has demonstrated good psychometric properties; and can be used as a reliable and valid measure to assess children's participation at the age of 6-12 years.

Translation, reliability and validity of Persian version of Adolescent/Adult Sensory Profile in dementia.

Our study aimed at the reliability and validity of the Persian version of the Adolescent/Adult Sensory Profile (AASP). This study was conducted on 130 people with dementia as well as 77 healthy elderlies. After translating the AASP into Persian, its content validity was determined based on 9 experts working in the same field. Cronbach's alpha and the Intraclass correlation coefficient (ICC) were calculated to assess the internal consistency and test-retest reliability of the Persian version of AASP. The two groups of people with dementia and healthy elderlies were compared in terms of scores in the four quadrants by performing an Independent t-test. All items in the Content Validity Ratio (CVR) and Content Validity Index (CVI) received an acceptable score. The Cronbach's alpha score for different parts of AASP was also calculated (α between 0.894 and 0.916; p < 0.001). The test-retest reliability of sub-tests of AASP was excellent (ICC between 0.885 and 0.948; p < 0.001). There was a statistically significant difference between the healthy Elderlies and dementia persons for low registration, sensory avoiding quadrants (p < 0.05). The Persian version of the AASP questionnaire is a reliable and valid questionnaire for people with dementia in Iran.
