A new SAS procedure for latent transition analysis: transitions in dating and sexual risk behavior

The set of statistical methods available to developmentalists is continually being expanded, allowing for questions about change over time to be addressed in new, informative ways. Indeed, new developments in methods to model change over time create the possibility for new research questions to be posed. Latent transition analysis, a longitudinal extension of latent class analysis, is a method that can be used to model development in discrete latent variables, for example, stage processes, over 2 or more times. The current article illustrates this approach using a new SAS procedure, PROC LTA, to model change over time in adolescent and young adult dating and sexual risk behavior. Gender differences are examined, and substance use behaviors are included as predictors of initial status in dating and sexual risk behavior and transitions over time.     

Social risk and protective factors for African American children's academic achievement and adjustment during the transition to middle school

The transition to middle school is often marked by decreased academic achievement and increased emotional stress, and African American children exposed to social risk may be especially vulnerable during this transition. To identify mediators and protective factors, the authors related severity and timing of risk exposure to academic achievement and adjustment between 4th and 6th grade in 74 African American children. Longitudinal analyses indicated that severity more than timing of risk exposure was negatively related to all outcomes and that language skills mediated the pathway from risk for most outcomes. Transition to middle school was related to lower math scores and to more externalizing problems when children experienced higher levels of social risk. Language skills and parenting served as protective factors, whereas expectations of racial discrimination was a vulnerability factor. Results imply that promoting parenting and, especially, language skills, and decreasing expectations of racial discrimination provide pathways to academic success for African American children during the transition from elementary to middle school, especially those exposed to adversity.     

Stereotyping and victim blaming of individuals with a laryngectomy

This study examined whether individuals with a laryngectomy are at risk for stereotyping and victim blaming. Undergraduate students (3 men and 41 women) volunteered to listen to a recording of a man who used tracheoesophageal speech or a man who was a typical adult speaker. A written vignette was provided prior to the listening activity to assess whether knowing that the speaker did or did not have a history of smoking affected the listeners' judgments of the speaker. Semantic differential data and qualitative responses indicated that participants did not report victim blaming; however, they did report that users of tracheoesophageal speech were less highly employable than typical adult speakers. Participants also indicated they relied on the vocal characteristics of speakers and used empathy- or experienced-based reactions to make judgments about users of such speech.     

Heuristic Implementation of Dynamic Programming for Matrix Permutation Problems in Combinatorial Data Analysis

Dynamic programming methods for matrix permutation problems in combinatorial data analysis can produce globally-optimal solutions for matrices up to size 30×30, but are computationally infeasible for larger matrices because of enormous computer memory requirements. Branch-and-bound methods also guarantee globally-optimal solutions, but computation time considerations generally limit their applicability to matrix sizes no greater than 35×35. Accordingly, a variety of heuristic methods have been proposed for larger matrices, including iterative quadratic assignment, tabu search, simulated annealing, and variable neighborhood search. Although these heuristics can produce exceptional results, they are prone to converge to local optima where the permutation is difficult to dislodge via traditional neighborhood moves (e.g., pairwise interchanges, object-block relocations, object-block reversals, etc.). We show that a heuristic implementation of dynamic programming yields an efficient procedure for escaping local optima. Specifically, we propose applying dynamic programming to reasonably-sized subsequences of consecutive objects in the locally-optimal permutation, identified by simulated annealing, to further improve the value of the objective function. Experimental results are provided for three classic matrix permutation problems in the combinatorial data analysis literature: (a) maximizing a dominance index for an asymmetric proximity matrix; (b) least-squares unidimensional scaling of a symmetric dissimilarity matrix; and (c) approximating an anti-Robinson structure for a symmetric dissimilarity matrix. We are extremely grateful to the Associate Editor and two anonymous reviewers for helpful suggestions and corrections.     

Grade retention and enrollment in post-secondary education

Students retained in grade have dropout rates three to seven times higher than do their promoted peers, yet little is known about the outcomes for the most persistent of the retained students who graduate high school. The purpose of this research was to examine the post-secondary (PSE) enrollment rates of retained but persistent high school graduates. Ten thousand 1992 high school graduates in the National Education Longitudinal Study (NELS) data base composed the sample. A logistic regression controlling for gender, socio-economic status (SES), race–ethnicity, and achievement yielded odds ratios indicating significantly lower odds of PSE enrollment for retained graduates compared to promoted graduates. Later grade retention generally reduced the odds of PSE enrollment. Findings suggest that retaining students may be related to negative educational outcomes not realized for many years.     

Evaluating Cognitive Training Outcomes: Validity and Utility of Structural Knowledge Assessment

Conventional approaches to evaluating cognitive outcomes of training typically use paper-and-pencil tests that emphasize gains or differences in declarative knowledge. Yet a key factor in differentiating expert and novice performance is the way individuals organize their knowledge. Accordingly, the acquisition of meaningful knowledge structures and methods of assessing structural knowledge are potentially important issues for designing and evaluating training programs. Two studies were conducted to examine the validity and utility of one structural assessment technique called Pathfinder (Schvaneveldt, Durso, & Dearholt, 1989). Results from academic and organizational samples indicated that Pathfinder measures of structural knowledge quality predicted individual differences in performance self-efficacy. After controlling for differences in declarative knowledge, measures of structural knowledge quality added to the prediction of performance self-efficacy in the student sample, but not in the organizational sample. The unique features and potential advantages of structural assessment for training evaluation are discussed.     

Dimensions of Perfectionism, Unconditional Self-Acceptance, and Depression

The current research investigated the associations among dimensions of perfectionism, unconditional self-acceptance, and self-reported depression. A sample of 94 students completed the Multidimensional Perfectionism Scale, the Unconditional Self-Acceptance Questionnaire, and a self-report depression measure. Correlational results indicated that all three trait dimensions of perfectionism (i.e., self-oriented, other-oriented, and socially prescribed perfectionism) were associated negatively with unconditional self-acceptance. Also, as expected, depression was associated with relatively low unconditional self-acceptance. Finally, a path analysis revealed that unconditional self-acceptance mediated the association between socially prescribed perfectionism and depression, and other-oriented perfectionism was found to affect depression only indirectly through its association with low levels of self-acceptance. The findings indicate that perfectionists evaluate themselves in terms of a contingent sense of self-worth, and as such, they are vulnerable to psychological distress when they experience negative events that do not affirm their self-worth.     

Predicting Positive Academic Intention Among African American Males and Females1

Significant attention has been given to the educational shortcomings of African American students. This study examined predictors of educational success among African American high school sophomores. It explored factors that predict differences in students’ academic intention to complete the school year, and how these factors differ by gender. The study was guided conceptually by the theory of planned behavior (TPB). We also assessed perceptions of self. Results indicated that most students had positive predispositions toward school‐year completion, with females being more positively oriented toward academic success than males. The TPB's attitude component was the only predictor tested to operate differentially across gender. Having a positive attitude toward school was a significantly greater predictor of intention to complete the school year for males than for females.     

Towards Culturally Relevant Preventive Interventions: The Consideration of Racial Socialization in Parent Training with African American Families

We present a rationale for the inclusion of culture-based parenting practices (i.e., racial socialization) in the design and implementation of empirically based parenting programs with African American families. We begin with a discussion of the limitations of the current parent training literature related to cultural considerations. Second, we examine the cultural and racial contexts of parenting for African Americans, review the literature on racial socialization, and discuss empirical support for considering its inclusion in parent training programs. Third, we examine the extent to which racial socialization operates in low-income African American families by presenting the findings from a qualitative pilot. We conclude by discussing how findings from the qualitative pilot might inform intervention efforts.     

Effects of Victim and Defendant Race on Jurors' Decisions in Child Sexual Abuse Cases1

We examined the influence of victim and defendant race, victim age, juror gender, and juror prejudice on jurors' decisions in child sexual abuse cases. In Experiments 1 and 2, mock jurors judged Black and Hispanic child victims to be more responsible for their sexual abuse than White victims. In Experiment 2, jurors assigned more guilt to defendants in cases involving victims and perpetrators of the same race compared to different races. Experiment 3 illustrated that laypeople believe same‐race cases to be more plausible generally. Experiment 2 revealed that high‐prejudiced White mock jurors made no more racially biased judgments than low‐prejudiced mock jurors. Finally, women were generally more pro‐victim in their case judgments than were men, and older victims were disadvantaged compared to younger victims in terms of perceived credibility and responsibility, and their cases were less likely to draw convictions.
