Assessment of a State TANF Funded IDA Initiative: A Case Study

Individual development accounts (IDAs), wealth-building programs for the working poor, have existed since the late 1980s. Current research suggests that IDA programs benefit families while contributing to local and state economies. This program evaluation assessed the impact of one state Temporary Assistance for Needy Families (TANF)-funded IDA initiative. Quantitative and qualitative data were collected from four agencies chosen using cluster sampling across the state. Agency programmatic and participant data from the last year of operation (N?=?160) were examined. Agencies also provided contact information for three participants who had graduated and three who exited the program prematurely in the past year of operation. In person, interviews were held with agency directors (n?=?6) and IDA participants (n?=?11) were interviewed by telephone. Results indicate that 69% (n?=?111) of IDA enrollees successfully completed the program. IDA participants who exited the program prior to completion also expressed benefits associated with the time in which they were involved. Programmatic and individual benefits and challenges reported guide recommendations for improving IDA marketability, participant outcomes, and organizational performance rates. A critical implication of the findings is the need to expand the use and design of IDA programs legislatively to better serve historically oppressed and working poor families more effectively.     

Multiplicative-interaction logit models for i×j×2 three-way tables

Multiplicative-interaction (M-I) logit models are proposed for three-way IxJx2 contingency tables where the third variable constitutes a binary response. Models are derived by assigning unknown scores to the categories and forming product interactions from them. Asymptotic results under special sampling constraints are derived for maximum likelihood estimates and the goodness-of-fit statistics. The class of models proposed in this paper are found to be useful when no obvious scores are available. An example is included.     

Pseudo maximum likelihood estimation for the dirichlet-multinomial distribution

Pseudo maximum likelihood estimation (PML) for the Dirich-let-multinomial distribution is proposed and examined in this pa-per. The procedure is compared to that based on moments (MM) for its asymptotic relative efficiency (ARE) relative to the maximum likelihood estimate (ML). It is found that PML, requiring much less computational effort than ML and possessing considerably higher ARE than MM, constitutes a good compromise between ML and MM. PML is also found to have very high ARE when an estimate for the scale parameter in the Dirichlet-multinomial distribution is all that is needed.     

Reporting cumulative proportion of subjects with an adverse event based on data from multiple studies

Experience has shown us that when data are pooled from multiple studies to create an integrated summary, an analysis based on naïvely‐pooled data is vulnerable to the mischief of Simpson's Paradox. Using the proportions of patients with a target adverse event (AE) as an example, we demonstrate the Paradox's effect on both the comparison and the estimation of the proportions. While meta analytic approaches have been recommended and increasingly used for comparing safety data between treatments, reporting proportions of subjects experiencing a target AE based on data from multiple studies has received little attention. In this paper, we suggest two possible approaches to report these cumulative proportions. In addition, we urge that regulatory guidelines on reporting such proportions be established so that risks can be communicated in a scientifically defensible and balanced manner.

Nursing-Home Resident Quality of Life: A Longitudinal Case Study Approach

Longitudinal quality-of-life (QOL) research incorporating multiple perspectives can add to knowledge about how nursing home residents experience QOL, but these methods are seldom used. This study employed interviews and participant observation to conduct multiple-perspective, longitudinal case studies of six residents. Close, reciprocal relationships with staff members, staff knowledge of residents, and autonomy were fundamental to QOL. Autonomy was experienced through choice and self-advocacy. Changes in QOL over time related to changes in resident health status, acclimation to the setting and family member availability. Study results may have implications for staffing and staff training.
