Spence Children’s Anxiety Scale (SCAS) is a 38 item scale that has two separate forms as child and parent report. Both forms consist of six subscales: panic attack and agoraphobia, separation anxiety, physical injury fears, social phobia, obsessive compulsive disorder, and generalized anxiety. In the present study, Spence Children’s Anxiety Scale Parent Version (SCAS-P) was first translated into Turkish, and then it was administered to 280 volunteer mothers to determine the factor structure and reliability of the scale. SCAS-P was previously adapted for Australian, German, and Japanese populations. Principal components factor analysis with varimax rotation revealed five factors in which all items had a factor loading of 0.30 or more. Since the number of items loaded more than one factor are too much and confirmatory factor analysis did not yield a result supporting 5 factor model, it was decided to keep the original 6 factors. Therefore, the further validity and reliability analysis have been conducted for 6 factors. The overall scale had a high degree of internal consistency, with an alpha coefficient of 0.88, and the split half reliability of 0.79. Internal consistency of the subscales ranged from 0.54 to 0.71. Inter-correlations among the factors and the total score of the scale were found to be satisfactory (r s 0.24 - 0.58, p < .01). Analysis indicated that the top 27th percentile of the sample was significantly scored higher than the bottom 27th percentile of the sample in terms of the total score and factor scores of the scale. (p < .01). The boys significantly scored higher than girls in term of the total score and lower order factor of the SCAS-P except panic attack and agoraphobia factors. There was no significant difference in term of age groups for all measures. The highest score reported by mothers was on the physical injury fear factor. These results are discussed in the light of the literature and the limitations of the study.
