Cytochrome P450 testing for better psychiatric care

Genotyping for CYP2D6 and CYP2C19 variations is emerging as a potentially useful clinical tool to help mental health professionals prescribe psychiatric medications for their patients. Cytochrome P450 testing uses a blood sample to determine an individual's required dosage of identified drugs that are metabolized by the two enzymes. To provide care for patients and families, nurses should be able to demonstrate identified essential nursing competencies related to genetics and genomics, which include an understanding of cytochrome P450 testing. As patient advocates, nurses are expected to understand how to identify patients most likely to benefit from CYP2D6 and CYP2C19 testing, how to ensure informed consent for such testing, and how to educate patients about testing and test results.     

State Income Inequality and Presidential Election Turnout and Outcomes*

Objective. This study examines the links among income inequality, voter turnout, and electoral choice at the state level in recent presidential elections. Methods. We introduce two new state‐level ecological data sets, estimated annual Gini coefficients of income inequality from 1969 to 2004 and a measure of income segregation across Census tracts within states in 1999. We test for associations among inequality, turnout, and party preference with cross‐sectional, fixed‐effects, and multilevel analyses. Results. The cross‐sectional effect of inequality on voter turnout and electoral choice is ambiguous. However, a fixed‐effects analysis links higher income inequality to lower voter turnout and also to a stronger Democratic vote. Multilevel results indicate that higher levels of economic segregation likewise are associated with depressed turnout, after controlling for individual voter characteristics and for state‐level income.     

Which factors explain the decline in infant and child mortality in Matlab,Bangladesh?

Infant and child mortality rates have decreased substantially in Matlab, Bangladesh, as they have in many developing areas. We use data from the Matlab Demographic Surveillance System on nearly 94,000 singleton live births that occurred between 1987 and 2002 to investigate the extent to which the change in mortality over this period can be explained by changes in reproductive patterns and socio-economic characteristics. We estimate Cox proportional hazards models for four subperiods of infancy and childhood. Changes over time in reproductive patterns (maternal age, parity, and pregnancy spacing) and in the socio-economic characteristics we consider (e.g. maternal education, SES) explain between 10 and 40% of the decline in mortality rates. Changes in maternal education explain the largest portion of the reduction in infant and child mortality over time that we are able to explain, followed by reductions in the incidence of short interpregnancy intervals. In the other direction, decreases in fertility over time led to increases in the proportion of births that were first births, putting upward pressure on mortality.

Should Mom go back to school? Post-natal educational attainment and parenting practices

Although the relationship between educational attainment and parenting practices is well documented, it is typically examined at only one point in time. What happens if mothers acquire more education after the birth of their children: do they alter their parenting practices? Panel data models based on longitudinal data from ECLS-K indicate that changes in mother’s educational attainment are positively associated with increases in parental school involvement, having books in the home, and participating in non-academic family activities, but not with attitudes toward discipline. Although post-natal maternal education does not change all aspects of parenting, our findings are broadly consistent with the theory of cultural mobility and provide insights into the extent of socio-cultural mobility in contemporary American society.     

Reliability reporting practices in youth life satisfaction research

Due to the emergence of positive psychology in recent years, a growing line of research has focused on aspects of psychological wellness rather than psychopathology. Within the context of positive psychology, life satisfaction has emerged as a key variable of study in relation to adult and youth populations. Accurate measurement of life satisfaction and subsequent interpretation of results requires that the assessment devices yield strong psychometric properties. In terms of consistent measurement, reliability estimates must be calculated with each administration, as changes in sample characteristics may alter the scale’s ability to generate reliable scores. Therefore, the present study was designed to address reliability reporting practices for three youth life satisfaction measures. Seventy-three occasions of use were identified in the literature for the three scales examined in this study. Results suggest that greater than half of the life satisfaction studies calculated reliability coefficients from their own data. A discussion of reliability from classical test theory is provided, examples of correct reliability reporting practices are given, and implications for reporting reliability are discussed.
