The aim of this study is to develop a mothers’ child-rearing attitude scale based on the enneagram personality typology.
The selection of questionnaire items has been conducted in the following three stages. In the first stage, 162 items were selected based on the descriptions about their child-rearing practices by 46 mothers of preschool children, who have completed 2 sessions of enneagram workshop and were able to identify their own enneagram personality types. In the second stage, 208 mothers of preschool children were tested using the scale developed in the first stage, and the collected data were analysed in relation to content validation for each personality type. Also, 4 enneagram specialists were tested using the same scale, and these data were analysed in terms of the respondents’ degrees of response congruence and content validity ratios. These processes resulted in 90 items composed of 10 items for each personality type. In the third stage, item analyses were conducted by calculating correlation coefficients between each item score and the total score of 10 items for each type. Thus, the final scale composed of 81 items were obtained by discarding the items that showed values of correlation coefficient lesser than .30. Although the 9th personality type showed relatively low reliability coefficients (Cronbach α = .43; test-retest reliability coefficients = .38), the remaining eight types showed high values for both coefficients ranging from .50 to .76. Especially, reliability coefficients for the total scores showed high values of .88, respectively. Accordingly, it is confirmed that the final scale can consistently measure the related traits for each personality type.
