Female conduct disorder: health status in young adulthood.

PURPOSE: One of the risk factors for poor adult health may be adolescent antisocial behavior, especially in girls. This study was conducted to determine if negative young adult health outcomes in girls who previously had adolescent antisocial behavior could be explained by demographic factors and pre-existing health problems. METHODS: This 3-year longitudinal study recruited 93 girls, ages 15-17 years (52 with conduct disorder [CD]; 41 with no psychiatric illness [normal controls; NC]) from the community. Baseline interviews of girls and parents collected demographic, psychiatric, and medical history data. Three annual interviews collected data about medical problems, health care service utilization, and reproductive health. In addition, the final follow-up included a standardized self-report questionnaire about young adult health status. RESULTS: CD and NC groups did not differ in age, racial composition, social class, proportion of smokers, or drug and alcohol experimentation. They were qualitatively different in baseline medical histories. Controlling for age at follow-up and baseline medical problems, the CD group as young adults had worse overall health, more discomfort, higher rates of unhealthy habits, lower rates of healthy behaviors, and more pregnancies at earlier ages. There were no group differences in rates of disorders, injuries, or health care usage. CONCLUSIONS: Adolescent girls with CD as young adults have poorer overall health, more discomfort, more health risk behaviors, and earlier onset of adult reproductive behaviors, even when controlling for demographic factors and pre-existing health history. Clinical and research implications are discussed.

Computerized adaptive measurement of depression: a simulation study.

BACKGROUND: Efficient, accurate instruments for measuring depression are increasingly important in clinical practice. We developed a computerized adaptive version of the Beck Depression Inventory (BDI). We examined its efficiency and its usefulness in identifying Major Depressive Episodes (MDE) and in measuring depression severity. METHODS: Subjects were 744 participants in research studies in which each subject completed both the BDI and the SCID. In addition, 285 patients completed the Hamilton Depression Rating Scale. RESULTS: The adaptive BDI had an AUC as an indicator of a SCID diagnosis of MDE of 88%, equivalent to the full BDI. The adaptive BDI asked fewer questions than the full BDI (5.6 versus 21 items). The adaptive latent depression score correlated r =.92 with the BDI total score and the latent depression score correlated more highly with the Hamilton (r =.74) than the BDI total score did (r =.70). CONCLUSIONS: Adaptive testing for depression may provide greatly increased efficiency without loss of accuracy in identifying MDE or in measuring depression severity.

Child sex differences in primary care clinicians' mental health care of children and adolescents.

BACKGROUND: Sex differences in the medical and mental health care of adults are well established. OBJECTIVE: To study the effect of child patient's sex on whether primary care clinicians (PCCs), including pediatricians, family physicians, and nurse practitioners, found or treated mental health problems in primary care settings. DESIGN: The data were collected by clinicians and parents from 21 065 individual child visits (50.3% girls) in 204 primary care practices. METHODS: Each PCC enrolled a consecutive sample of approximately 55 children and adolescents aged 4 to 15 years. Parents filled out questionnaires, including the Pediatric Symptom Checklist, before seeing the clinician. Clinicians completed a survey after the visit about the psychosocial problems and recommended treatments, but they did not see the results of the Pediatric Symptom Checklist or any other data collected from the parents. RESULTS: Boys were more likely to be seen for a mental health-related visit and by a clinician who identified them as "my patient." Boys with parent-reported symptom profiles that were similar to those of girls were more likely to be identified as having attention-deficit/hyperactivity problems or behavior or conduct problems and less likely to be identified as having internalizing problems. Adjusting for parent-reported symptoms, PCCs were more likely to prescribe medications for boys. Child sex differences in referrals to mental health specialists and the provision of counseling to families were not statistically significant. CONCLUSION: There are substantial sex differences in the mental health care of children in the primary care system.

Multidimensional adaptive testing for mental health problems in primary care.

OBJECTIVES: Efficient and accurate instruments for assessing child psychopathology are increasingly important in clinical practice and research. For example, screening in primary care settings can identify children and adolescents with disorders that may otherwise go undetected. However, primary care offices are notorious for the brevity of visits and screening must not burden patients or staff with long questionnaires. One solution is to shorten assessment instruments, but dropping questions typically makes an instrument less accurate. An alternative is adaptive testing, in which a computer selects the items to be asked of a patient based on the patient's previous responses. This research used a simulation to test a child mental health screen based on this technology. RESEARCH DESIGN: Using half of a large sample of data, a computerized version was developed of the Pediatric Symptom Checklist (PSC), a parental-report psychosocial problem screen. With the unused data, a simulation was conducted to determine whether the Adaptive PSC can reproduce the results of the full PSC with greater efficiency. SUBJECTS: PSCs were completed by parents on 21,150 children seen in a national sample of primary care practices. RESULTS: Four latent psychosocial problem dimensions were identified through factor analysis: internalizing problems, externalizing problems, attention problems, and school problems. A simulated adaptive test measuring these traits asked an average of 11.6 questions per patient, and asked five or fewer questions for 49% of the sample. There was high agreement between the adaptive test and the full (35-item) PSC: only 1.3% of screening decisions were discordant (kappa = 0.93). This agreement was higher than that obtained using a comparable length (12-item) short-form PSC (3.2% of decisions discordant; kappa = 0.84). CONCLUSIONS: Multidimensional adaptive testing may be an accurate and efficient technology for screening for mental health problems in primary care settings.

Primary care clinicians' use of standardized tools to assess child psychosocial problems.

BACKGROUND AND OBJECTIVES: Children's psychosocial problems are prevalent but often inaccurately diagnosed. This study investigated primary care clinicians' (PCCs) use of standardized tools for psychosocial problems among children in whom they reported finding a problem. METHODS: The data consisted of 21 065 unique visits by children ages 4 to 15 years in 204 practices. Parents completed questionnaires before seeing the PCCs, who completed a survey after the visit. This analysis included 3934 children who were recognized by PCCs as having one or more psychosocial problems. The primary outcome was the PCCs' usage of a tool to assess child psychosocial problems. RESULTS: PCCs used a tool in 20.2% of visits where a psychosocial problem was recognized, whereas 50% of PCCs never used such tools. Tools were less likely to be used by female PCCs and family practitioners and were less likely to be used with girls and African American children. Tools were more frequently used with children with attention problems, during visits for psychosocial problems, and when the PCC knew about the problem before the visits. CONCLUSIONS: PCCs use standardized tools infrequently to screen for, confirm, or monitor psychosocial problems.
