Predictors of Early Engagement in Home Visitation

Predictors of engagement in mothers receiving home visitation in the first year of service was examined. Early engagement was studied in three ways: (1) length of time active in the program during the first year of service (duration), (2) number of visits received (quantity), and (3) gaps in service between visits (consistency). Examined visits received in 515 first-time mothers in a Healthy Families America (HFA) program. Parameters of engagement were investigated, and predictors of engagement were identified using demographics and the Kempe Family Stress Inventory. Inclusive of the Assessment Visit, 31.8% of mothers disengaged prior to the first month of service. Remaining active in the program was associated with being Caucasian, and increased parenting risk (mental health/substance abuse history, low social support, increased stress). Most mothers had fewer home visits than prescribed. Gaps in prescribed service were common, with 89.4% of mothers experiencing gaps between visits of 1 month, and dropping to 16.4% having gaps of 2 months. In contrast to findings from clinic-based interventions, early engagement in home visitation is associated with lower levels of functioning and acute needs. These findings add to a growing body of literature suggesting that increased adversity promotes engagement in prevention programs in general, and home visitation programs in particular. To the extent that mothers who are actively engaged in home visitation are likely to have increased psychosocial needs, curricula may require modification and augmentation to address these needs and optimize program effectiveness.

Determination of opiates and cocaine in hair using automated enzyme immunoassay screening methodologies followed by gas chromatographic-mass spectrometric (GC-MS) confirmation

The objective of this study was to develop a two-step strategy for analysis of opiates and cocaine in hair samples involving an immunological screening procedure followed by confirmation of results using gas chromatography-mass spectrometry (GC-MS). A semi-quantitative automated competitive enzyme-linked immunosorbent assay (ELISA) methodology using Oral Fluid Micro-Plate Enzyme Immunoassays (Orasure Technologies, Inc.) was developed and validated. Applicability was proven by analysis of authentic head hair samples from drug users (n=103) and from opiate associated fatalities (n=21). The optimum cutoff values for the ELISA tests were 0.1 ng cocaine-equivalents/mg hair and 0.05 ng morphine-equivalents/mg hair using a 50 mg hair sample. Both ELISA tests had a sensitivity of 100%, the specificity was 66% for cocaine-equivalents and 42% for morphine-equivalents. The intraassay precision was 11% for the cocaine and 3% for the opiates ELISA, while interassay precision was 12% for the cocaine and 4% for the opiates ELISA test. The actual analyte concentrations in the hair samples were determined using GC-MS and were between 0.04 and 5.20 ng/mg for heroin (HER), between 0.04 and 30.01 ng/mg for 6-monoacetylmorphine (MAM), between 0.03 and 11.87 ng/mg for morphine (MOR), between 0.02 and 1.84 ng/mg for codeine (COD), between 0.02 and 2.48 ng/mg for acetylcodeine (AC), between 0.01 and 21.37 ng/mg for cocaine (COC), between 0.03 and 10.51 ng/mg for benzoylecgonine (BE) and between 0.05 and 1.26 ng/mg for cocaethylene (CE). The automated ELISA tests were proven to be valid screening procedures for the detection of cocaine and opiates in hair as confirmed by GC-MS. Screening methods provide rapid and inexpensive automated pre-test procedures to detect drugs in hair or other matrices. For forensic purposes screening therefore represents an ideal complement to routinely applied GC-MS procedures.     

The Substitution Approach To Intergovernmental Relations: The Case Of OSHA

Federal legislation of the last two decades has substantiallyreduced state autonomy in dealing with many regulatory issues.Participation in the implementation of these federal programsmay, however, enable states to exert some leverage over policyoutcomes. Variations in state leverage no doubt exist from oneintergovernmental grant program to the next. Substitution authoritymay be one variable accounting for this variation. Under a substitutionapproach, a federal agency cannot only sever the flow of fundsto a grantee; it can also step in and operate a program if statesfail to meet expectations or choose not to participate. Thisarticle generates more basic propositions about the substitutionapproach by analyzing its implementation under the OccupationalSafety and Health Act of 1970. The article examines the roleplayed by substitution authority in motivating the OccupationalSafety and Health Administration (OSHA) to adopt an aggressiveposture toward the states. The article then assesses whetherOSHA's aggressiveness prompted state grantees to exert considerableeffort on behalf of program goals. Finally, the implicationsof current reform proposals, which call for a sorting out offunctions between the states and the federal government, receiveattention.

Intimate partner violence research in the health care setting: what are appropriate and feasible methodological standards?

The past 20 years of research has exposed the profound cost of intimate partner violence (IPV) in health care problems and health care dollars for victims and bystanders. As a result, professional organizations encourage clinicians to identify IPV victims and to refer them to community resources. To date there is little evidence to show the value of these efforts, and many completed studies are criticized for methodological weaknesses. IPV studies are challenging to design, and the double-blind randomized controlled trial may be an impossible standard. To move forward, funders and study committees are encouraged to reassess the standards for IPV research methodologies.
