The Weekly Adjustment Indicators Checklist: An Application in the Child Welfare Field

Research on the effectiveness of various home-based interventions implemented in the 1980s and 1990s indicates that results have been equivocal. Because of the unique and complex behavioral challenges presented by each family and the need for individualized treatments and long-term interventions for these families, group research and evaluation designs are often insufficient in assessing effectiveness of home-based interventions. Alternative evaluation strategies are needed. The purpose of this exploratory study was two-fold: (a) to investigate the applicability and acceptability of the Weekly Adjustment Indicators Checklist (WAIC) in monitoring adult and child behaviors and (b) to monitor, on an on-going basis, the progress of a family referred to an urban family preservation and reunification program. The target family on whom data were collected consisted of a 13-year old girl and her foster parent who was her maternal aunt. The findings of this study indicate that the WAIC is applicable in monitoring the progress of children and adults in care and that it has the endorsement of its user, namely, the direct care provider. Other results of the study, limitations of the study, and future research needs are discussed.

Automatic quantitation of multiple sclerosis lesions on MR images

A two-pronged approach for the automatic quantitation of multiple sclerosis (MS) lesions on magnetic resonance (MR) images has been developed. This method includes the design and use of a pulse sequence for improved lesion-to-tissue contrast (LTC) and seeks to identify and minimize the sources of false lesion classifications in segmented images. The new pulse sequence, referred to as AFFIRMATIVE (Attenuation of Fluid by Fast Inversion Recovery with MAgnetization Transfer Imaging with Variable Echoes), improves the LTC, relative to spin-echo images, by combining Fluid-Attenuated Inversion Recovery (FLAIR) and Magnetization Transfer Contrast (MTC). In addition to acquiring fast FLAIR/MTC images, the AFFIRMATIVE sequence simultaneously acquires fast spin-echo (FSE) images for spatial registration of images, which is necessary for accurate lesion quantitation. Flow has been found to be a primary source of false lesion classifications. Therefore, an imaging protocol and reconstruction methods are developed to generate "flow images" which depict both coherent (vascular) and incoherent (CSF) flow. An automatic technique is designed for the removal of extra-meningeal tissues, since these are known to be sources of false lesion classifications. A retrospective, three-dimensional (3D) registration algorithm is implemented to correct for patient movement which may have occurred between AFFIRMATIVE and flow imaging scans. Following application of these pre-processing steps, images are segmented into white matter, gray matter, cerebrospinal fluid, and MS lesions based on AFFIRMATIVE and flow images using an automatic algorithm. All algorithms are seamlessly integrated into a single MR image analysis software package. Lesion quantitation has been performed on images from 15 patient volunteers. The total processing time is less than two hours per patient on a SPARCstation 20. The automated nature of this approach should provide an objective means of monitoring the progression, stabilization, and/or regression of MS lesions in large-scale, multi-center clinical trials. ^

THE DISCHARGED PSYCHIATRIC PATIENT: POST-HOSPITAL ADJUSTMENT AND FACTORS AFFECTING REHOSPITALIZATION

Discharged psychiatric patients were studied six months post-discharge to determine those demographic, social and clinical characteristics affecting positive or negative adjustment and the degree to which the use of mental health services and medication compliance mediated the effects. With the exception of those with primary or secondary diagnoses of OBS, substance abuse or mental retardation, sixty-three psychiatric subjects between the ages of eighteen and sixty-four were chosen from all admissions into the hospital and interviewed six months after discharge using a specially designed questionnaire.^ The subjects' adjustment to community living was found to be marginal. Although not engaged in destructive activities, over half were living with their family members who supported them financially and emotionally. Most were unemployed and had been so for a long time. Others worked sporadically and frequently changed residences. Most did have substantial social ties with extended family and with friends with whom they interacted regularly, but one-fourth were socially isolated. Almost three-quarters continued to obtain regular mental health services after discharge and followed medication instructions under the supervision of their physician. The use of mental health services after discharge and the use of medication did not appear to affect the subjects' community adaption or their rate of rehospitalization.^ Forty percent of those discharged were rehospitalized by the end of the follow-up period. Four levels of risk of rehospitalization emerged. The highest risk was associated with a history of five or more prior hospitalizations, living alone, and social isolation. One third or more of the subjects expressed a need for more counseling, leisure time activities, case-manager assistance, vocational guidance, supervised housing, and placement into a transitional residential treatment program.^ Recommendations were made to enhance the ability to predict recidivism, to develop interorganizational casework management programs linking the patient and family to the community mental health system and to create computerized tracking and monitoring programs that systematically report patient treatment regimen and progress cross-sectionally and longitudinally. ^
