Abstract

Neurodevelopmental maturation takes place in a social environment in addition to a neurobiological one. Characterization of social environmental factors that influence this process is therefore an essential component in developing an accurate model of adolescent brain and neurocognitive development, as well as susceptibility to change with the use of marijuana and other drugs. The creation of the Culture and Environment (CE) measurement component of the ABCD protocol was guided by this understanding. Three areas were identified by the CE Work Group as central to this process: influences relating to CE Group membership, influences created by the proximal social environment, influences stemming from social interactions. Eleven measures assess these influences, and by time of publication, will have been administered to well over 7,000 9–10 year-old children and one of their parents. Our report presents baseline data on psychometric characteristics (mean, standard deviation, range, skewness, coefficient alpha) of all measures within the battery. Effectiveness of the battery in differentiating 9–10 year olds who were classified as at higher and lower risk for marijuana use in adolescence was also evaluated. Psychometric characteristics on all measures were good to excellent; higher vs. lower risk contrasts were significant in areas where risk differentiation would be anticipated.

Assessing the measurement properties of neighborhood scales: from psychometrics to ecometrics.

Mahasin S. Mujahid, Ana V. Diez Roux, Jeffrey D Morenoff … (2007)

Most studies examining the relation between residential environment and health have used census-derived measures of neighborhood socioeconomic position (SEP). There is a need to identify specific features of neighborhoods relevant to disease risk, but few measures of these features exist, and their measurement properties are understudied. In this paper, the authors 1) develop measures (scales) of neighborhood environment that are important in cardiovascular disease risk, 2) assess the psychometric and ecometric properties of these measures, and 3) examine individual- and neighborhood-level predictors of these measures. In 2004, data on neighborhood conditions were collected from a telephone survey of 5,988 residents at three US study sites (Baltimore, Maryland; Forsyth County, North Carolina; and New York, New York). Information collected covered seven dimensions of neighborhood environment (aesthetic quality, walking environment, availability of healthy foods, safety, violence, social cohesion, and activities with neighbors). Neighborhoods were defined as census tracts or census clusters. Cronbach's alpha coefficient ranged from 0.73 to 0.83, with test-retest reliabilities of 0.60-0.88. Intraneighborhood correlations were 0.28-0.51, and neighborhood reliabilities were 0.64-0.78 for census tracts for most scales. The neighborhood scales were strongly associated with neighborhood SEP but also provided information distinct from neighborhood SEP. These results illustrate a methodological approach for assessing the measurement properties of neighborhood-level constructs and show that these constructs can be measured reliably.

The roles of conflict engagement, escalation, and avoidance in marital interaction: a longitudinal view of five types of couples.

John Gottman (1993)

Seventy-three couples were studied at 2 time points 4 years apart. A typology of 5 groups of couples is proposed on the basis of observational data of Time 1 resolution of conflict, specific affects, and affect sequences. Over the 4 years, the groups of couples differed significantly in serious considerations of divorce and in the frequency of divorce. There were 3 groups of stable couples: validators, volatiles, and avoiders, who could be distinguished from each other on problem-solving behavior, specific affects, and persuasion attempts. There were 2 groups of unstable couples: hostile and hostile/detached, who could be distinguished from each other on problem-solving behavior and on specific negative and positive affects. A balance theory of marriage is proposed, which explores the idea that 3 distinct adaptations exist for having a stable marriage.
