Handicap-related problems in mothers of children with physical impairments.

An inventory was developed for the measurement of handicap-related problems experienced by mothers of children with chronic physical conditions and an initial evaluation of its psychometric properties was completed in a sample of 119 mothers of children with physical or sensory impairments. Principal component analysis of the Handicap-related Problems for Parents Inventory (HPPI) yielded three subscales, which accounted for 54% of the total variance. The HPPI demonstrated excellent internal consistency for each scale and total score. It also generally had good test-retest reliability over 6-, 12-, and 18-month periods. There was minimal covariation between HPPI scores and demographic status. Concurrent validity was demonstrated by significant correlations between appropriate HPPI scales and measures of daily stress and the child's physical condition or disability status. Support for its construct validity was obtained when expected convergent and discriminant relationships were confirmed between HPPI scales and measures of maternal adaptation, maternal social support, and child behavior problems. Among other results, HPPI scores predicted maternal adaptation 18 months later. The potential uses of the HPPI in research and intervention with mothers of children with chronic physical conditions were discussed.
