This study was designed to establish and validate a multidimensional empirically based typology of clinically referred adolescent substance abusers. A total of 141 adolescent substance abusers, most of whom were male, African-American, and juvenile justice involved, comprised the study sample. Youth and their parents completed comprehensive…

Drawing upon self-categorization theory, we predicted that the content of children's stereotypes concerning the gender in-group would be contextually variable. Two studies are reported, each looking at five-, seven-, and 10-year-old children's stereotypes of the gender in-group in two different contexts. Study 1 examined judgements of the…

This study examined children's reading performance and its developmental trajectories during the first and the second grade. Ninety children were tested five times on word reading and reading comprehension. Qualitatively different groups were identified through cluster analysis: Competent, Technical, and Poor Readers. The results showed that the…

Nine children with severe-profound prelingual hearing loss and single-word reading scores not more than 10 months behind chronological age (Good Readers) were matched with 9 children whose reading lag was at least 15 months (Poor Readers). Good Readers had significantly higher spelling and reading comprehension scores. They produced significantly…

The hypothesis that an economic recession in society leads to class equalisation in the recruitment of new students to higher education is tested, using data from Sweden. The 1990s is a period suitable for these analyses, as the recession started in 1991, reached the highest unemployment level in 1993; finally, at the end of the decade the labour…

Despite ongoing concern about substance use during adolescence, very little is known about alcohol and drug use among teens living in affluent social settings. In this longitudinal study, cluster analysis was used to characterize patterns of substance use and change in other dimensions of psychosocial adjustment within a cohort of 292 high school…

In separate studies, observers viewed upright biological motion, inverted biological motion, or arbitrary motion created from systematically randomizing the positions of point-light dots. Results showed that observers (a) could learn to detect the presence of arbitrary motion, (b) could not learn to discriminate the coherence of arbitrary motion,…

Hierarchical agglomerative cluster analysis (HACA) may yield different solutions under permutations of the input order of the data. This instability is caused by ties, either in the initial proximity matrix or arising during agglomeration. The authors recommend to repeat the analysis on a large number of random permutations of the rows and columns…

The occupational identity statuses of 232 college students were analyzed by examining their family emotional environment and the identity control processes that drive career decision making. Results of multivariate analysis showed that each family differentiation construct, family tolerance for connectedness, and separateness explained significant…

Mokken scale analysis (MSA) can be used to assess and build unidimensional scales from an item pool that is sensitive to multiple dimensions. These scales satisfy a set of scaling conditions, one of which follows from the model of monotone homogeneity. An important drawback of the MSA program is that the sequential item selection and scale…

The study of emerging adulthood--the prolonged transition to adulthood extending into the 20s--is a rapidly growing area of research. Although identity issues are prominent during this period, the role of personal agency and individualization in the identity formation process during these years is not well understood. This study examines three…

This study examined the convergent relations between scores from four clinical clusters from the Woodcock-Johnson III Tests of Cognitive Abilities (WJ III) and measures of executive functions using a sample of school-aged children and a sample of adults. The WJ III clinical clusters included the Working Memory, Cognitive Fluency, Broad Attention,…

Community policing agencies seek to engage communities to build working partnerships, solicit the input of neighborhood residents, and stimulate informal control of crime. A common barrier to these efforts is a lack of citizen participation. The purpose of this article is to assess the relationship between neighborhood-level variables and citizen…

Marriage markets have become increasingly filled with those who already have children, which may discourage marriage. Research has generally failed to assess the role of prospective stepchildren in new union formation, particularly from the point of view of the men who might become their stepfathers. Using data from the National Survey of Families…

In the common two-step structural equation modeling process, modifications are routinely made to the measurement portion of the model prior to assessing structural relations. The effect of such measurement model modifications on the structural parameter estimates, however, is not well known and is the subject of the current investigation. For a…
