Summary: The Quebec Incidence Study of Reported Child Abuse and Neglect (QIS/EIQ) is conducted every five years with Quebec’s CPS caseworkers. Aside from estimating the annual incidence of child maltreatment reports investigated by CPS, the study produces the only reliable province-wide data to describe the maltreatment situations, the psychosocial profiles of the children and their parents, and their housing conditions. At every QIS cycle (1998, 2003, 2008, 2014), the approach has been essentially the same: A representative sample of child maltreatment reports assessed by CPS from October 1 to December 31 of the target year is constituted (sample size varies from one cycle to the next; in 2014, it totalled 4,011 reports) and, for each report in the sample, the primary caseworker completes a study form (QISF) after completing each report assessment.
Another way to measure maltreatment is to code CPS report using a standardized coding grid. The instrument most often used for this purpose in research is the Modified Maltreatment Classification System (MMCS; English et al., 1997). It has been used in more than 75 studies (Huffhines et al., 2016) and is considered the most complete instrument of its kind by experts in the field (Jackson et al., 2019). The MMCS is a revised and improved version of the Maltreatment Classification System (MCS; Barnett et al., 1993), which was updated as part of the well-known LONGSCAN longitudinal study in the United States. A revision of the MMCS was called for, however, to take account of the findings of the past 25 years of research, primarily regarding psychological maltreatment. Whereas the MMCS comprises only one global category for “emotional maltreatment”, research has shown that various subtypes of emotional or psychological maltreatment are identifiable (Glaser 2002, 2011; Hart et al., 2017) and numerous researchers have underscored the importance of refining how psychological maltreatment is measured (English et al., 2015a, 2015b; Tailleu et al., 2016). S. Monette completed an update of the MMCS, which we call the Extended Modified Maltreatment Classification System (EMMCS). The reason for this update was to define different subtypes of psychological maltreatment. The EMMCS has all of the strong suits of the MMCS, namely, it still covers the following dimensions: 1) types and subtypes (augmented) of maltreatment; 2) severity per event; and 3) frequency of maltreatment events. However, it also covers the following new dimensions: 4) developmental periods of exposure; and 5) maltreatment chronicity. Some parental risk factors and some child adverse life event risk factors are also now documented.
The aim of this project is to compare different methods of measuring maltreatment based on data in CPS files. More specifically, three methods will be applied to 200 files and compared: 1) a QIS form completed by a CPS caseworker, which is the usual method used in the QIS; 2) a QIS form completed by a research assistant (based on CPS narrative reports); and 3) coding of CPS narrative reports with the EMMCS by two research assistants. The sub-objectives of this study include verifying whether rates (McNemar test) and agreement (kappa statistic) for maltreatment are similar: 1) between the QIS form completed by a caseworker and the QIS form completed by a research assistant; and 2) between the QIS form completed by a caseworker and the EMMCS coded by two research assistants (consensual coding). Another sub-objective is to validate the EMMCS by: 3) determining the instrument’s inter-rater reliability (200 files coded by two research assistants) and: 4) determining the instrument’s convergent validity by comparing the maltreatment rates obtained with the EMMCS and with the QIS form completed by a research assistant.
