A history of abuse in childhood increases the likelihood of lifetime psychopathology; this association appears stronger for women than men.

The reliability and validity of the 12-item General Functioning (GF) subscale of the McMaster Family Assessment Device (FAD) is reported here. Psychometric properties of the FAD have been previously determined, but no independent assessment has been made of the GF subscale, which was used to measure family functioning in the Ontario Child Health Study (OCHS). Reliability was measured by Chronbach's alpha and split-half correlation. Validity was assessed by hypothesizing the relationships expected between the GF scores and other family variables included in the OCHS data set. The results indicate good reliability, and all hypotheses of validity were supported. The brevity and ease of administering the GF subscale recommend it for further use in survey research in which a global assessment of family functioning is required.

EW ISSUES IN THE FIELD OF FAM-ily violence generate as much controversy as screening women for intimate partner violence (IPV) in health care settings. 1,2 Herein, we use the term screening to refer to universal routine inquiry: "a standardized assessment of patients, regardless of their reasons for seeking medical attention," 1 aimed at identifying women who are experiencing or have recently experienced IPV.Proponents of screening emphasize the following as a rationale for its implementation: the high prevalence of IPV and associated impairment, 3,4 the high level of acceptability among women about such inquiry, 5,6 the availability of feasible screening techniques, 7,8 and the opportunity to offer support and refer-rals to patients once IPV is identified. 6,9 Organizations such as the US Preventive Services Task Force 10 and the Canadian Task Force on Preventive Health Care 11 have concluded that insufficient evidence exists to recom-For editorial comment see p 568.

The objective of this paper is to present data from the Ontario Child Health Study on the prevalence of attention deficit disorder with hyperactivity (ADDH). The overall prevalence of ADDH was 9.0% in boys and 3.3% in girls. There were no significant differences in the prevalence of ADDH by age or urban-rural status, but the disorder was significantly more common in boys than in girls. The prevalence of various subtypes of ADDH was also explored: attention deficit with and without hyperactivity, situational vs pervasive ADDH, and ADDH with and without other disorders. The clinical implications of these findings are discussed.

Background Few studies have examined stress reactivity and its relationship to major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) among maltreated youth. We examined differences between maltreated and control participants in heart rate and cortisol resting and reactivity levels in response to a psychosocial stressor. Methods We recruited 67 female youths aged 12 to 16 with no prior history of depression from child protection agencies and a control group of 25 youths matched on age and postal code. Child maltreatment was measured with two self-report instruments. Psychiatric status was assessed using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children. Results Piecewise multilevel growth curve analysis was used to model group differences in resting and reactivity cortisol levels and heart rate in response to the Trier Social Stress Test (TSST). During the resting period, both the maltreated and control groups showed a similar decline in levels of cortisol. During the reactivity phase, youth in the control group showed an increase in cortisol levels following the TSST and a gradual flattening over time; maltreated youth exhibited an attenuated response. This blunted reactivity was not associated with current symptoms of MDD or PTSD. There were no group differences in resting and reactivity levels of heart rate. Conclusions These findings provide further support for hypothalamic-pituitary-adrenal axis dysregulation among maltreated youth. Since the ability to respond to acute stressors by raising cortisol is important for health, these findings may assist in understanding the vulnerability of maltreated youth to experience physical and mental health problems.

A four-attribute health state classification system designed to uniquely categorize the health status of all individuals two years of age and over is presented. A social preference function defined over the health state classification system is required. Standard multi-attribute utility theory is investigated for the task, problems are identified and modifications to the standard method are proposed. The modified method is field tested in a survey research project involving 112 home interviews. Results are presented and discussed in detail for both the social preference function and the performance of the modified method. A recommended social preference function is presented, complete with a range of uncertainty. The modified method is found to be applicable to the task—no insurmountable difficulties are encountered. Recommendations are presented, based on our experience, for other investigators who may be interested in reapplying the method in other studies.

This article describes the development and evaluation of the revised Ontario Child Health Study (OCHS) scales to measure conduct disorder, oppositional disorder, attention-deficit hyperactivity disorder, overanxious disorder, separation anxiety and depression based on DSM-III-R symptom criteria. Problem checklist assessments were obtained from parents and teachers of children aged 6-16 and youths aged 12-16 drawn from: (1) a general population sample (N = 1751); and (2) a mental health clinic sample (N = 1027) in the same industrialized, urban setting. Evaluation of the revised OCHS scales indicates that they possess adequate psychometric properties and provide an efficient means to obtain measurements of childhood psychiatric disorder, in general population studies, that correspond to DSM-III-R classification of disorder.
