Cross-sectional data from the Medical Outcomes Study (MOS) were analyzed to test the validity of the MOS 36-Item Short-Form Health Survey (SF-36) scales as measures of physical and mental health constructs. Results from traditional psychometric and clinical tests of validity were compared. Principal components analysis was used to test for hypothesized physical and mental health dimensions. For purposes of clinical tests of validity, clinical criteria defined mutually exclusive adult patient groups differing in severity of medical and psychiatric conditions. Scales shown in the components analysis to primarily measure physical health (physical functioning and role limitations-physical) best distinguished groups differing in severity of chronic medical condition and had the most pure physical health interpretation. Scales shown to primarily measure mental health (mental health and role limitations-emotional) best distinguished groups differing in the presence and severity of psychiatric disorders and had the most pure mental health interpretation. The social functioning, vitality, and general health perceptions scales measured both physical and mental health components and, thus, had the most complex interpretation. These results are useful in establishing guidelines for the interpretation of each scale and in documenting the size of differences between clinical groups that should be considered very large.Source

Policy Brief: Addressing Social Determinants of Health through Community Health Workers: A Call to ActionLondon, Katharine; Damio, Grace; Ferrazo, Meredith; Perez-Escamalla, Rafael; Wiggins, Noelle (2018-01-30)This technical report was compiled by the Hispanic Health Council in partnership with Southwestern AHEC and a panel of Community Health Worker Policy Research Experts which included our Katharine London from the Center for Health Law and Economics. The report offers a number of policy recommendations for community health workers for communities that might benefit from community-based services. The report offers recommendations on; payment of community health workers; community health worker caseloads; community health worker recruitment; community health worker training; reflective and trauma-informed mentoring and supportive supervision of community health workers; integration of community health workers into care teams; documenting the effect of community heal worker services on social determination of health. The Hispanic Health Council believes a service design that effectively supports community health workers would incorporate the seven areas of policy recommendation included in this report.

A Public Health Framework for the State Mental Health Authority: A Call for Action by Massachusetts Consumers and Family MembersDelman, Jonathan (2006-01-01)During the Spring of 2006, Consumer Quality Initiatives (CQI) conducted 20 focus groups across the state, 12 with adults with mental illness, 3 with parents of youth with serious emotional disorder, 2 with youth with SED, 1 with family members of adult consumers, and 2 with youth in transition. Supported by a contract with Massachusetts Department of Mental Health (DMH), the goal was to assist DMH in framing the criteria for its upcoming reprocurement. Our findings reveal a frustration with an approach to health care delivery that focuses primarily on the provision of psychiatric care (egs, medication, therapy, hospitalization). We reviewed the focus group reports to identify the most significant themes, which clustered within eight broad categories.

Making the Case for Sustainable Funding for Community Health Worker Services: Talking to Payers and ProvidersLondon, Katharine (2018-01-27)In this presentation, Katharine London of the Center for Health Law and Economics makes her case for offering sustainable funding for community health worker services. Research has shown community health workers can have a distinct impact on health systems, helping them improve population health and contain costs, while also promoting health equity and community engagement. This presentation was designed to assist CHWs and other advocates in engaging with policymakers and payers to support CHW sustainability and develop a financial plan for their CHW work. It was presented as part of a CHW Sustainability event held at the Families USA’s annual conference, Health Action 2018: Staying Strong for America’s Families, in Washington, DC.
