障害児をもつ母親の心的ストレスに関する研究 (II)

We investigated theitem analysls of QRS which Holroyd had developed since 1973. Data used for our analysis were 236 QRSs which were answered by 28 mothers of autism, 33 mothers of blind, 67 mothers of cripple and 108 mothers of mental retardation. Ages of children of 4:6-12:11 were 122, and 13:0-19:10 were 114. Ages of mothers 25:O-39:11 were 105, and 40:0-60:O were 131.
We calculated corrected item-total correlations in 206 items. Correlations above 50 were only 71 items.
Secondly We factor analysed items in each scale by means of principal component method. The first factor extracted accounted for low proportions of the total variance in each scale.
Thirdly we factor analysed items separately in three categories. In Parent problems we extracted five factors - Mother's Affliction, Pessimism about Child Development, Overprotection / Dependancy, Anxiety for the Future of Handicapped child, and Social Isolation. In Family problems we extracted three factors - Burden for the Member of the Family, Fmancial Problems, and Lack of Family Integration. In Child problems we extracted three factors - Intellectual Incapacitation, Physical Incapacitation, and Need for the Care of the Child.
These results showed QRS did not consist of 15 scales Holroyd had assumed.
We preceeded to investigate from the result of our factor analysis. We calculated the factor scores for each case in eleven factors. The main results were as follows. The mothers with high factor scores in Child problems showed the high factor scores in Parent problems and Family problems The mothers of autism reported more problems than other groups. The second stressful mothers were cripple. The mothres of blind were the least stressful of four groups. The mothers with institutionalized mentally retarded children reported greater stress than the mother with noninstitutionalized.
We believe these results gave us the basic and many informations to understand the psychic stress of the mother and the family with handicapped child.
