The extent of change in the performance of local mental health authorities (LMHAs) and in the development of community support systems (CSSs) is assessed for nine demonstration cities that participated in the RWJF Program on Chronic Mental Illness and one comparison site. Parallel measures of LMHA and CSS performance were obtained from two data sources (key informant and interorganizational network surveys) conducted at each site at two times during the demonstration: 1989 and 1991. Findings indicate that the LMHAs were successfully implemented at most demonstration sites, but changes in the CSSs lagged behind LMHA performance levels. The amount of system change tended to be greater when estimated from network versus key informant data.

OBJECTIVES This study evaluated the hypothesis that greater integration and coordination between agencies within service systems is associated with greater accessibility of services and improved client housing outcomes. METHODS As part of the Access to Community Care and Effective Services and Supports program, data were obtained on baseline client characteristics, service use, and 3-month and 12-month outcomes from 1832 clients seen at 18 sites during the first year of program operation. Data on interorganizational relationships were obtained from structured interviews with key informants from relevant organizations in each community (n = 32-82 at each site). RESULTS Complete follow-up data were obtained from 1340 clients (73%). After control for baseline characteristics, service system integration was associated with superior housing outcomes at 12 months, and this relationship was mediated through greater access to housing agencies. CONCLUSIONS Service system integration is related to improved access to housing services and better housing outcomes among homeless people with mental illness.

Planning for the delivery of community mental health services has evolved from models of services within individual agencies to community-wide systems of care, but development of methodologies for assessing system performance has lagged behind. This article presents one approach to systemlevel assessment by viewing children’s mental health systems as an interorganizational network. Data are presented on two county-based child mental health systems in North Carolina that participated in the Robert Wood Johnson Foundation Mental Health Services Program for Youth. Site-specific data on client referrals, fund exchanges, and information flows were collected at two time points (1991 and 1993) to measure the cohesiveness and concentration of the service system using network k-core analyses. In addition, stakeholder ratings of service adequacy, quality, availability, coordination, and overall demonstration project goal attainment were obtained at both time periods. Findings indicate that the rural system was outperforming the urban system at the time of the first survey, but the urban system caught up over the study interval. There was high agreement between the network and stakeholder ratings of system performance at both time periods. The method of data collection and analysis used in this study provides tools that can be used in a variety of settings to assess service system growth and development.

Abstract Although network analysis is becoming a more viable and informative methodology for the study of interorganizational behavior, issues involving the accuracy and reliability of self-reported or ‘cognitive’ network data are still unresolved. Two networks based on information and coordination relationships in each of four major cities are examined. Reliability of responses is assessed as the percent of confirmed relationships between agency respondents and by correlating the extent of agreement in each network. In addition, two possible measurement errors are examined: systematic errors which are network-independent and idiosyncratic errors which are network-dependent. These errors are assessed through correlational analyses of the intensity of an organizations relationships with the number of its relationships that are confirmed in each network. Also systematic errors are accounted for by calculating the proportion of confirmed relationships within the different response categories used to judge the strength of relationship between ego organizations in the network. It is concluded that boundary spanning personnel of organizations can provide fairly reliable responses to network generated questions, but that errors in the data tend to be systematic in the way that prior studies of interpersonal cognitive networks report.

The community support network has beenwell-established as a requirement for communitytreatment of individuals with severe mental disorders.This network generally consists of a multidisciplinaryset of organizations that interrelate in some mannerwith individuals in the community. The question ofcoordination within this network has been muchdiscussed; however little published research hasempirically examined the types and extent of coordinationamong network organizations. In particular, littleattention has been given to community support networksin rural communities. In each of seven rural counties, information was obtained on interactions amongorganizations in the community support network. Thesenetworks were analyzed to yield information on networkdensity and centralization. Using measures of centrality, the most central organizations ineach network were identified. Exchanges of informationwere the most common type of interaction amongorganizations in each network. Client referrals occurred less frequently, and sharing of resources wasan even rarer phenomenon. Network analysis of communitysupport networks provides an objective perspective onthe structure of community support networks. An understanding of exchange among organizationswithin these networks is of value to administrators,clinicians, and planners interested in achieving greatereffectiveness, as well as to patients, their families, and advocacy groups concerned with access andquality of care.

The major objective of this research is to examine and characterize service delivery systems for persons with mental illness in a resource scarce environment, i.e. a rural area characterized by persistent poverty and disadvantaged poulations. Although a number of studies have investigated the integration of mental health, general health, and social services, few have focused on systems of care in rural areas. To characterize service delivery systems, this exploratory study uses a case study approach that includes network analysis, quantitative analysis, and a system assessment. The findings suggest that scarcity of resources in these rural environments is an overriding factor in the development of an integrated service delivery system for persons with a mental illness. With no psychiatrists, long waits for commitment, and few emergency accomodations, these rural environments afford service providers little opportunity for proactive or strategic planning. In fact, we view the development of integrated (e.g. client referral and technical information exchange) service networks in rural communities, especially areas of extreme resource scarcity, as problematic. The resource exchange networks that exist are best characterized as informal, moderately centralized, and of limited density. This translates into a system of care that is provider-driven and crisis-oriented.

ABSTRACT This paper describes a two-tiered community intervention model in response to a call from the Center for Mental Health Services for the development of best-practice strategies for homeless mothers with mental health and/or substance use disorders and their children. This model incorporates best practice principles gained from previous research projects pitched at the system and client levels. The model has been conceptualized, presented, and funded by CMHS and is currently being implemented in a local community. This model is unique in that it develops an intervention that addresses both levels of service delivery (i.e., system and client) in a single project. Blending systems integration/wraparound service philosophy and consumer-driven/strength-based development approaches provides a model that encompasses interventions at the individual client level via supported case management, and improved coordination and collaboration at the service system level. While this model was developed for a specific community population, the approach is general inits applicability to other areas of practice.
