The purpose of this study was to develop a mearsure for evaluation of the level of isolation of the children without friends(from third to sixth grade) on the basis of the estimation by children. The subjects in this study were 392 boys and girls sampled from three elementary schools. The scale consists of 32 items categorized into four domains, that is, emotional loneliness, social loneliness, emotional isolation and social isolation. The data collected were analyzed using the following statistical methods. First, factor analysis were employed to supply evidence for the construct validity of the test. Second, Pearson`s r was computed between this test with five other scales to supply evidence for the concurrent validity of the test. Five other scales are UCLA-R, LSDS, BDI, MEPS and PR. Third, Cronbach α, split-half reliability coefficient and test-retest coefficient for reliability were computed. The results of this research were as follows; 1.The construct validity of the test is supported by the results of factor anlysis and it was found that this test assess a construct, isolation and it is composed by four factors. 2. The concurrent validity, correlations between the scores on this test and those on UCLA-R, LSDS, BDI. MEPS and PR, were computed. They ranged totally from .22 to . 53. 3. The range of the reliability of the test is from .82 to .86 which is considered to be high.
