[Parental stress in mothers of preschool children: validation and Quebec norms for the Parental Stress Inventory].

The authors examine the metrological qualities of a French version of the Parenting Stress Index (Abidin, 1983; Loyd and Abidin, 1985) based on a sampling of 122 Québec mothers with a preschool child. Results show that the Parental Stress Inventory presents internal consistency indices that are equivalent to those obtained in the U.S. sampling. However, the samplings differ on seven out of 13 subscales, as well as concerning the scores obtained for the child's realm and the overall stress, Québec mothers show higher scores. The factorial analysis of the subscales supports the existence of a hierarchical structure composed of a general factor of parental stress and two specific factors: the realm of the child and the realm of the parent. The score relative to the realm of the parent varies according to the socioeconomic level and the marital status of the mother. The mother's age is negatively correlated with the score of the child's realm. The child's aggressiveness/hyperactivity level, as perceived by the teacher in a class situation, is positively correlated with the score of the subscale Difficulty to accept the child's characteristics and the subscale Distraction and hyperactivity of the child. The authors present benchmarks that were developed in order to take into account the noted differences between the Québec and U.S. samplings.
