Park, Young Sook

Abstract

OBJECTS: This study aimed at an examination of the item analysis and reliability of the Family screening test which was developed to assess the family's charateristics and the degree of family psychopathology from March 15 to May 30 1996
METHODS
The subjects were 467 housewives who were sampled by the random sampling method in Seoul. This family screening test is composed of 11 subscales, the self-report measure, and a 5-point scale.
RESULTS
1) 98 items were selected by the item analysis and reliability evaluation among the original 1999 items which were categorized 11 subscales. 2) The internal consistency of the Cronbach's alpha and the speraman-Brown split-half correlation coefficients were more than 0.70 for all scales exept 8,9,10,11 scales. 3) The reliability coefficients of the Cronbach's alpha and the split-half correlation for 8,9,19,11 scales were less than 0.70 which were evaluated to have the insufficient corrected item-total correlation coefficients.
CONCLUSIONS
It was suggested that 8,9,10,11 scales need to the most items for increasing the reliability coefficients through the complemantary work.
