Mastery motivation is a psychological force that stimulates an individual to attempt to master a task that is challenging to him or her. This prospective longitudinal study examined the relationship between maternal stress, using the Parenting Stress Index-Short Form, and infant mastery motivation, using the Dimensions of Mastery Questionnaire, for 150 mother-infant pairs assessed at both 6- and 18-months of age. Infants of mothers with elevated stress levels at 6 months tended to show lower mastery motivation at 18 months (standardized beta = −.46, p=.001). Conversely, infants with lower general competence (standardized beta = −.24, p=.021) and lower persistence during social interactions with other children (standardized beta = −.18, p=.037) at 6 months of age had mothers with elevated total stress at 18 months of age. Implications for programs which simultaneously intervene with child and mother are discussed.
The authors investigated the reliability and construct validity of the Marschak Interaction Method Rating System (MIMRS), a new observational scoring system for the play-based Marschak Interaction Method (MIM), particularly its ability to capture high-risk parenting in adolescent motherchild dyads. The MIMRS demonstrated high interrater reliability and high internal consistency. Convergent validity was supported by moderately negative correlations between the MIMRS and the Parenting Stress Index/Short Form. The MIMRS demonstrated good contrasted groups validity, differentiating between 15 adolescent-child dyads and 16 adult-child comparison dyads, even after adjustment for differences in children's age. These results suggest that the MIMRS has the potential be a valuable rating system for research and practice with the MIM, as well as understanding and assessing parent-child relationships.
The specialized needs of pregnant and parenting women in the treatment of drug addiction must not be underestimated. The impact of substance abuse on developmental outcomes for young infants and children supports the notion that attention to the parent-child relationship is a critical aspect of addiction treatment for this population. As such, the standard of care appears to be shifting from separating mothers and young children while the mother completes addiction treatment to women residing with their children while in treatment and receiving concurrent addiction treatment and parenting education. While parenting education is important, it may not provide the needed relationship intervention to address the myriad of issues often present for female recovering addicts and their children. This article describes the evolution and workings of a program for integrating infant mental health practice into a long-term residential treatment community for pregnant and parenting women with addiction. The principles and structure of the modified therapeutic community are described, as are the ways in which infant mental health practice have been effectively integrated and incorporated into the addiction treatment philosophy. A case example is provided, and clinical implications are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
