SCHOOL ANXIETY INVENTORY: RELIABILITY AND VALIDITY EVIDENCE IN A SAMPLE OF SLOVENIAN ADOLESCENTS

The purpose of this study was to examine the reliability and validity of the School Anxiety Inventory (SAI) using a sample of 646 Slovenian adolescents (48% boys), ranging in age from 12 to 19 years. Single confirmatory factor analyses replicated the correlated four‐factor structure of scores on the SAI for anxiety‐provoking school situations (Anxiety about School Failure and Punishment, Anxiety about Aggression, Anxiety about Social Evaluation, and Anxiety about Academic Evaluation), and the three‐factor structure of the anxiety response systems (Physiological Anxiety, Cognitive Anxiety, and Behavioral Anxiety). Equality of factor structures was compared using multigroup confirmatory factor analyses. Measurement invariance for the four‐ and three‐factor models was obtained across gender and school‐level samples. The scores of the instrument showed high internal reliability and adequate test–retest reliability. The concurrent validity of the SAI scores was also examined through its relationship with the Social Anxiety Scale for Adolescents (SASA) scores and the Questionnaire about Interpersonal Difficulties for Adolescents (QIDA) scores. Correlations of the SAI scores with scores on the SASA and the QIDA were of low to moderate effect sizes.     

The Effect of Differential Motivation on IRT Linking

The purpose of this study was to investigate whether simulated differential motivation between the stakes for operational tests and anchor items produces an invalid linking result if the Rasch model is used to link the operational tests. This was done for an external anchor design and a variation of a pretest design. The study also investigated whether a constrained mixture Rasch model could identify latent classes in such a way that one latent class represented high‐stakes responding while the other represented low‐stakes responding. The results indicated that for an external anchor design, the Rasch linking result was only biased when the motivation level differed between the subpopulations to which the anchor items were administered. However, the mixture Rasch model did not identify the classes representing low‐stakes and high‐stakes responding. When a pretest design was used to link the operational tests by means of a Rasch model, the linking result was found to be biased in each condition. Bias increased as percentage of students showing low‐stakes responding to the anchor items increased. The mixture Rasch model only identified the classes representing low‐stakes and high‐stakes responding under a limited number of conditions.     

Eye Contact Modulates Cognitive Processing Differently in Children With Autism

In humans, effortful cognitive processing frequently takes place during social interaction, with eye contact being an important component. This study shows that the effect of eye contact on memory for nonsocial information is different in children with typical development than in children with autism, a disorder of social communication. Direct gaze facilitated memory performance in children with typical development (n = 25, 6 years old), but no such facilitation was seen in the clinical group (n = 10, 6 years old). Eye tracking conducted during the cognitive test revealed strikingly similar patterns of eye movements, indicating that the results cannot be explained by differences in overt attention. Collectively, these findings have theoretical significance and practical implications for testing practices in children.     

Ethnic Differences in Associations Among Popularity,Likability, and Trajectories of Adolescents' Alcohol Use and Frequency

Two‐part latent growth models examined associations between two forms of peer status (popularity, likability) and adolescents' alcohol use trajectories throughout high school; ethnicity was examined as a moderator. Ninth‐grade low‐income adolescents (N = 364; M_age = 15.08; 52.5% Caucasian; 25.8% African American; 21.7% Latino) completed sociometric nominations of peer status and aggression at baseline, and reported their alcohol use every 6 months. After controlling for gender, aggression, ethnicity, and socioeconomic status, popularity—but not likability—prospectively predicted alcohol use trajectories. However, these effects were moderated by ethnicity, suggesting popularity as a risk factor for alcohol use probability and frequency among Caucasian and Latino, but not African American adolescents. Results suggest that developmental correlates of peer status should be considered within cultural context.     

Infant Temperament: Stability by Age,Gender, Birth Order,Term Status,and Socioeconomic Status

Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.     

Children's Temperament and Academic Skill Development During First Grade: Teachers' Interaction Styles as Mediators

The present study followed 156 Finnish children (M_age = 7.25 years) during the first grade of primary school to examine to what extent parent‐ and teacher‐rated temperament impacts children's math and reading skill development during the first grade, and the extent to which this impact would be mediated by teachers' interaction styles with the children. The results showed that the impact of children's low task orientation and negative emotionality on their math skill development was mediated via teachers' behavioral control and, among girls, also by psychological control. The negative impact of children's inhibition on math skill development, in turn, was not mediated via teachers' interaction styles. Temperament did not predict the children's reading skill development during first grade.
