Comparison of 12-Year-Old Children with Prenatal Exposure to Cocaine and Non-Exposed Controls on Caregiver Ratings of Executive Function

Differences in caregiver reported executive function in 12-year-old children who were prenatally exposed to cocaine (PCE) compared to children who were not prenatally exposed to cocaine (NCE) were assessed. One hundred and sixty-nine PCE and 169 NCE, primarily African-American, low socioeconomic status children participated in a prospective longitudinal study. The Behavior Rating Inventory of Executive Function (BRIEF) Parent Form was administered. Two broadband BRIEF scores (Behavioral Regulation Index (BRI) and Metacognition Index (MI)) and a summary Global Executive Composite (GEC) were computed. Multiple and logistic regression analyses were used to assess the effects of amount of PCE on executive function, controlling for covariates including caregiver (rater) psychological distress, child’s gender and other prenatal drug exposure variables. After adjustment for covariates, amount of PCE was associated with the GEC and two MI subscales, Plan/Organize and Monitor, with heavier exposure associated with more problems of executive function. An amount of PCE by gender interaction revealed amount of PCE effects in other remaining subscales of the MI (Initiate, Working Memory, and Organization of Materials) only among girls. Head circumference did not mediate the effects of cocaine on outcomes. Higher current caregiver psychological distress levels were independently associated with poorer ratings on the executive function scales. Assessment and targeted interventions to improve metacognitive processes are recommended for girls who were prenatally exposed to cocaine.     

The global economic crisis and domestic political agendas

There is an ongoing debate within the economic voting literature about whether the economy's salience systematically fluctuates over time or is constant. The recent global economic slowdown provides leverage to test the proposition that voters give greater weight to economic performance when it is weak. Data on voters' issue priorities from 2000 to 2011 shows that voters were more likely to consider the economy an important issue during periods of bad or volatile economic performance. A weak economy also focuses voter attention on corruption and crime while reducing attention to social policy and foreign affairs. Crime rates, terrorist attacks, globalization, and the level of development also affect the economy's place on the electoral agenda. Thus one impact of the recent financial downturn was a shift toward economic voting in countries where it was deepest.
