Catching sight of children with internalizing symptoms in upper elementary classrooms

Teachers play a crucial role in the assessment of children's internalizing symptoms but may not always succeed in accurately identifying such symptoms in class. Using a multilevel structural equation modeling (MSEM) approach, this study aimed to explore teacher and child characteristics that may explain measurement bias in teachers' ratings of internalizing symptoms at the between- and within-teacher level. Upper elementary school teachers (N = 92, 74.9% female) filled out the Strengths and Difficulties Questionnaire, Student-Teacher Relationship Scale, and Student-Specific Teacher Self-Efficacy Scale for randomly selected children (N = 690, 50.5% girls, Grades 3–6) from their classrooms. Participating teachers and children also responded to several background questions. Multilevel SEMs suggested that teachers' self-efficacy beliefs toward, relationship experiences with, and externalizing symptom ratings of individual children affected their ratings of these children's internalizing symptoms at the within-teacher level. Specifically, given equal levels of internalizing behavior, teachers were likely to systematically under-identify symptoms of anxiety and over-identify bullying for children with more externalizing behavior and conflictual relationships, or in circumstances where teachers had lower self-efficacy. Children with high levels of closeness received systematically higher ratings on somatic complaints and lower ratings on solitary behavior and peer problems. At the between-teacher level, less experienced teachers were more likely to over-identify symptoms of worries than were more experienced teachers, given equal levels of internalizing symptoms. As such, these findings extend the limited body of evidence on children's internalizing symptoms in upper elementary school.     

Are you a “bad driver” all the time? Insights from a weekly diary study on personality and dangerous driving behavior

Research concerning dangerous driving behavior has often favored studying inter-individual differences at the expense of intra-individual ones (especially when verifying its associations with personality factors). Using a 7 weeks diary approach, we aimed at exploring the intra-individual variation of dangerous driving behavior (Errors, Violations and Aggressive driving). Also, we verified if our outcomes could be predicted by both situational variables (weekly km, felt traffic pressure and traffic mood) and dispositional ones (Big-Five personality factors, age and gender). Our findings revealed that Violations, Verbal & Physical aggression and Vehicle aggression had similar intra- to inter-individual variation ratios, with approximately 45% of variance at the intra-individual level. In contrast, Errors had only about 30% of variance at the intra-individual level. Traffic mood was the only significant intra-individual predictor, negatively correlating with all outcomes. Excepting Agreeableness, all personality factors were related to at least one dangerous driving behavior (especially consistent for the association between Extraversion and Aggressive driving). Also, women reported lower levels than men on all outcomes but Errors. Overall, this study raises some questions about the assumed stability of driving behavior, while at the same time confirming several relational patterns between personality factors and dangerous driving.     

Inter- and intra-individual variability in the kinematics of the back squat

The purpose of this study was to explore the level of inter- and intra-individual variability in the kinematic profiles of the back squat movement among skilled weightlifters. Ten competitive weightlifters volunteered for participation in this study. Barbell velocity (V_Barbell) and angular velocity of the ankle (ω_Ankle), knee (ω_Knee) and hip joint (ω_Hip) were obtained by kinematic recording of six trials at 90% of 1RM in the back squat. Inter-individual variability was assessed by analysing inter-individual differences in the velocity curves through the statistical parametric mapping method. Intra-individual variability was assessed through a correlation analysis between the barbell velocity curves of each trial for each participant. Partial least squares regression analysis, was performed to relate changes in intra-individual variability to movement and anthropometric characteristics. Significant inter- and intra-individual differences were identified in V_Barbell, ω_Ankle, ω_Knee, and ω_Hip (p ≤ 0.05). Having a short trunk and thigh, and a long shin in combination with greater anterior-posterior displacement of the barbell and slower velocities during the acceleration phase increased intra-individual movement consistency over movement variability. The results of the present study clearly demonstrate that skilled weightlifters display both significant inter- and intra-individual variability in the successful execution of the back squat.     

Capturing age-group differences and developmental change with the BASC Parent Rating Scales

Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998) Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. The importance of test–content parallelism for developmental studies is discussed.     

Predicting parental social influences: The role of physical activity variability

Objectives

This study examined how variations in the activity of adolescents might relate to the social influences used by parents. Specifically, mean differences in activity across adolescents (individual differences) as well as variation in activity within adolescents (intra-individual variation) were used to predict the use of family social influence.

Design

A prospective design was used.

Methods

High school students (N = 329) completed measures of activity (six times) and social influences received from family (positive, negative, collaborative) (five times) over a one-year period. A multilevel analysis was used to predict each of the three types of social influence. The predictors included activity in two forms: The individual’s mean level of activity (i.e., individual differences) and activity at the previous time point as a deviation from the individual’s mean activity level (i.e., intra-individual variation).

Results

Controlling for age, gender and school, results revealed that both individual differences in mean activity level (b = 0.04, p < .001) and intra-individual variation in activity (b = −0.02, p = .055) predicted use of collaborative influence. For positive influence, only individual differences in mean activity level was a predictor (b = 0.02, p < .001). Neither form of activity predicted parental use of negative influence.

Conclusions

Results revealed support for the positive relationship between both positive and collaborative types of influence and individual differences in activity that is typically reported in the literature. However, a negative relationship between intra-individual variation in activity and collaborative social influences also was found. This negative relationship, where lower activity than normal by the adolescent was related to a greater use of collaborative influence by the parent, may be indicative of a regulatory form of social influence.     

A review of the factors that can influence the effectiveness of sexual offender treatment: Risk,need, responsivity,and process issues

The aim of this paper is to review various factors that may affect the effectiveness of sex offender treatment. First, attention to risk level is discussed as an important factor in terms of ensuring that treatment is administered according to the level of an offender's problems and that treatment addresses criminogenic needs. Second, a number of responsivity/intra-individual characteristics (e.g., psychopathy, motivation, and locus of control), which may influence treatment outcome, are examined. Third, the importance of considering process issues, such as the therapeutic climate of the group, the composition of the group, and therapist characteristics is discussed. Finally, suggestions for future research and for optimizing the effectiveness of sex offender treatment are provided.     

TESTICULAR SELF-EXAMINATION: VALIDATION OF A TRAINING STRATEGY FOR EARLY CANCER DETECTION

Testicular self-examination (TSE) can lead to early diagnosis and treatment of testicular cancer, the third leading cause of death in young men. We evaluated the effectiveness of a brief and specific checklist for teaching TSE skills. Ten men were videotaped while performing testicular self-examinations before and after training. The TSE training resulted in large and significant increases in the number of TSE steps completed and duration of the TSE. Two urological validation measures supported the improvements observed in the mens' self-examinations. Subjects reported continued performance of TSE during a follow-up telephone interview. This pilot study indicates that a brief and specific checklist is an effective strategy for teaching early cancer detection skills.     

Étude exploratoire de la stabilité à long terme des indices standard du WISC-IV

By a Test–Retest procedure, this study explores the long-term stability of the French WISC-IV index scores. The average Test–Retest interval was 2.33 years. The sample consisted of 96 non-clinical children aged between 8 and 12 years. Mean difference between the two testings was not statistically significant for VCI, PRI, WMI, GAI and FSIQ. Test–Retest reliability correlations between the two assessments are high for VCI, GAI and FSIQ (ranging from .81 to .82). An analysis of the performance differences between two assessments indicates intra-individual stability for WMI and GAI. In sum, only GAI demonstrates reliable long-term stability at an inter-and intra-individual level.     

Intra- and Inter-Individual Differences in Adolescent Depressive Mood: the Role of Relationships with Parents and Friends

Utilizing four waves of data from 1126 secondary school Dutch adolescents (Mage = 13.95 at the first wave; 53% boys), the current study examined the interplay between parent-adolescent and friend-adolescent relationship quality (satisfaction and conflict) in relation to adolescents’ depressive mood. Using multilevel analyses, the interacting effects of parent/friend relationship quality on depressive mood were tested at both the intra- and inter-individual level. Analyses at the intra-individual level investigated whether individual depressive mood fluctuated along with changes in their social relationships regardless of one’s general level of depressive mood; and analyses at the inter-individual level examined whether the average differences in depressive mood between adolescents were associated with different qualities of social relationships. We interpreted the patterns of interactions between parent and friend relationships using four theoretical models: the reinforcement, toxic friends, compensation, and additive model. The results demonstrate the covariation of parent- and friend- relationship quality with adolescents’ depressive mood, and highlight that parent and peer effects are not independent from each other—affirming the compensation and additive models at the intra-individual and the reinforcement and additive models at the inter-individual level. The findings highlight the robustness of the protective effects of parent and peer support and the deleterious effects of conflictual relationships for adolescent mental health. The results have implications for both the theoretical and practical design of (preventive) interventions aimed at decreasing adolescents’ depressive mood.     

Sensorimotor Variables and Forced Expiratory Volume as Correlates of Speed,Accuracy, and Variability in Reaction Time Performance in Late Adulthood

The relationship between performance on measures of sensorimotor and physiological function and performance on measures of reaction time (RT) was investigated using an individual differences approach. Older participants showed greater intra-individual variability on the RT measures. They were also slower on measures of four choice visual RT but not on measures of three choice auditory RT. Sensorimotor and physiological variables explained nearly all the age differences in performance on the RT tasks and showed similar patterns of relationships with measures of speed, accuracy, and intra-individual variability. The results support a common factor interpretation of the relationships among these variables in old age.     

Intra-Individual Variability of Normal and Educable Mentally Retarded Children on a Coincidence Timing Task

A visual coincidence timing task was used to compare the level of performance (constant error) and the intra-individual variability of 100 normal and 100 educable mentally retarded children. The mean performance of the intellectually normal children on this task was significantly superior to that of the retarded children, and the intra-individual variability of the latter was significantly greater than that of the former. The hypothesis that high intra-individual variability and depressed level of performance are closely associated was not supported.     

Consistency as a Factor in Predicting Grades

This study attempted to determine whether individual differences in intra-individual consistency are reliable over time and whether future grades can be predicted more accurately for consistent students—those whose grades do not vary much from course to course—than for students with “spotty” records. Measures of intra-individual consistency were computed from grades obtained early in school and from grades obtained later for several samples of students. These measures showed no reliability over time, and there were no differences between consistent and inconsistent students with regard to the accuracy of prediction of future grades. It was recommended that considerable caution be used in attributing any significance to the degree of consistency or inconsistency manifested by a student's academic record.     

The Power to Detect and Predict Individual Differences in Intra-Individual Variability Using the Mixed-Effects Location-Scale Model

Our goal is to provide empirical scientists with practical tools and advice with which to test hypotheses related to individual differences in intra-individual variability using the mixed-effects location-scale model. To that end, we evaluate Type I error rates and power to detect and predict individual differences in intra-individual variability using this model and provide empirically-based guidelines for building scale models that include random and/or systematically-varying fixed effects. We also provide two power simulation programs that allow researchers to conduct a priori empirical power analyses. Our results aligned with statistical power theory, in that, greater power was observed for designs with more individuals, more repeated occasions, greater proportions of variance available to be explained, and larger effect sizes. In addition, our results indicated that Type I error rates were acceptable in situations when individual differences in intra-individual variability were not initially detectable as well as when the scale-model individual-level predictor explained all initially detectable individual differences in intra-individual variability. We conclude our paper by providing study design and model building advice for those interested in using the mixed-effects location-scale model in practice.     

Individual Differences In Intra-Individual Variability

For each of 75 Ss several estimates of intra-individual variations were calculated for each of 4 motor skills. The reliability of intra-individual variation for these data, estimated from Pearson productmoment correlations, ranged from r = .31 to r = .51 (in all cases p < .05). It was also found that in 3 of the 4 skills, intra-individual variation correlated significantly (r = .36, .54, .55) with mean performance level. Second order partial correlations, holding constant the effect of mean performance level, were then used to estimate the reliability of intravariation. These correlations were statistically significant and ranged from r = .27 to r = .34. When correlations of intra-individual variation were calculated among the four skills it was demonstrated that intra-individual variation was approximately 95 to 100% task specific.     

Inter-individual and intra-individual variability of the N2 component: On reliability and signal-to-noise ratio

The nogo N2 component, an anterior negative peak supposed to be generated in the anterior cingulate cortex, has been used as an indicator of conflict monitoring and response conflict in basic and clinical research. Here, we investigate the reliability and the signal-to-noise ratio (SNR) of inter-individual differences of the N2 amplitudes as well as of intra-individual standard deviations of N2 amplitudes. Effects of the number of nogo epochs, type of summary measure (peak vs. average amplitude), and filter cut-offs (1–12 Hz vs. 1–30 Hz) are investigated. A sample of N = 32 participants, performed a go/nogo task. Excellent Cronbach’s alpha coefficients (?.90) were obtained for the fronto-central average N2 amplitude at 40 nogo epochs and for the peak N2 amplitude at 60 nogo epochs. The SNR was higher for the average nogo N2 amplitude compared to the peak N2 amplitude. Split-half reliability coefficients of the intra-individual standard deviation of the nogo N2 amplitudes were at least moderate. Based on these results we provide suggestions for a reliable N2 measurement. Moreover, although intra-individual variability has often been conceived as noise the present findings support the idea that intra-individual N2 variability incorporates systematic variance.     

Within-person profiles of teachers' motivation to teach: Associations with need satisfaction at work,need-supportive teaching,and burnout

ObjectivesAccording to self-determination theory, teachers can engage in their job for a variety of reasons. Motivation can be controlled (feeling externally or internally pressured) or autonomous in nature (enjoying teaching or valuing its importance). The aim of this study was to identify motivational profiles (i.e., within-teacher combinations of autonomous and controlled motivation) and to examine associations between these motivational profiles and the following variables: experiences of need satisfaction, dimensions of teaching style, and burnout.DesignThis study has a cross-sectional design based on teacher reports.MethodsA total of 201 PE teachers signed in for an online questionnaire on motivation to teach, need satisfaction at work, need-supportive teaching and burnout.ResultsFour hypothesized motivational profiles were retained: a poor quality, a low quantity, a high quantity, and a good quality group. The good quality group displayed the most optimal pattern of antecedents and outcomes, closely followed by the high quantity group. The poor quality group displayed the most maladaptive pattern of associations with antecedents and outcomes, even in comparison to the low quantity group.ConclusionsEndorsing a specific motivational profile has implications for teachers' need satisfaction and burnout, but also for students, because the quality of teachers' motivation also shows in provided need support toward the students. This finding might convince school policy members and other stakeholders to value the importance of nurturing teachers' autonomous motivation.     

Encouraging the practice of testicular self-examination: a field application of the theory of reasoned action

Identified factors associated with testicular self-examination (TSE) within the context of the theory of reasoned action. Subjects (232 male college students) received instruction in TSE and completed a questionnaire operationalizing the components of the theoretical model. During the following 6 weeks, a field intervention was conducted in which approximately half the subjects were exposed to posters reminding them to perform the exam. Multiple-regression analyses revealed that intention to perform TSE correlated significantly with attitude and subjective norm and that consideration of self-efficacy and TSE knowledge improved the prediction of intention. Significant differences in outcome expectancies and normative beliefs were found between subjects who intended to perform the exam and those who did not. Intention was moderately (r = .30, p less than .001) correlated with behavior; the intention-behavior correlation, however, was stronger among subjects who intended to perform the exam and were exposed to the posters (r = .55, p less than .001).     

Practice and Persuasive Frame: Effects on Beliefs,Intention, and Performance of a Cancer Self-Examination1

Many behaviors are performed less frequently than intended because they require knowledge and skill to overcome behavioral barriers. This experiment tested effects of two factors, direct experience and message frame, that were hypothesized to affect men's intention to perform the testicle self-exam for cancer (TSE) and their actual exam performance, in part by affecting their knowledge and beliefs about overcoming TSE performance barriers. Men's experience performing the TSE on a life-like model and the frame (negative, positive, or neutral) of the recommendation promoting the exam were manipulated factorially. Consistent with prediction, men who practiced (vs. did not practice) the self-exam: (a) endorsed stronger beliefs about behavior-specific knowledge (e.g., ability to imagine a lump), (b) held more positive intention, and (c) translated that intention more consistently into self-reported action, in part because their behavior-specific knowledge increased their tendency to act on their intention. Consistent with action phase theory (Gollwitzer, 1990), intention related more strongly to behavior-specific beliefs than to general, long-term beliefs, and more strongly than attitude related to behavior-specific beliefs. These findings have practical and theoretical implications for promoting healthful and other intended behaviors.     

Long-Term Development of Employee Well-Being: A Latent Transition Approach

The long-term development of employee well-being is still poorly understood. Consequently, in this three-wave 10-year longitudinal study among Finnish managers (n = 402) the development of employee well-being was examined in in detail. Specifically, the long-term development of job-related affective well-being was investigated at the intra-individual level, simultaneously taking into account positive and negative indicators of well-being, the level of well-being, and the direction of change. Further, the issue how (changes in) job resources and employee well-being were related across time was examined. By applying a novel person-centered methodology, factor mixture modeling and latent transition analysis, the results revealed that the development of favorable job-related affective well-being was eight times more probable than that of unfavorable development across the 10-year study period. Job resources predicted a high level of job-related well-being and, also, job resources increased along with favorable changes in well-being. Overall, the findings contribute to knowledge in the area of positive occupational health psychology by offering a detailed picture of the level of job-related affective well-being and its development over time.     

Individual differences in cognitive plasticity: an investigation of training curves in younger and older adults

To date, cognitive intervention research has provided mixed but nevertheless promising evidence with respect to the effects of cognitive training on untrained tasks (transfer). However, the mechanisms behind learning, training effects and their predictors are not fully understood. Moreover, individual differences, which may constitute an important factor impacting training outcome, are usually neglected. We suggest investigating individual training performance across training sessions in order to gain finer-grained knowledge of training gains, on the one hand, and assessing the potential impact of predictors such as age and fluid intelligence on learning rate, on the other hand. To this aim, we propose to model individual learning curves to examine the intra-individual change in training as well as inter-individual differences in intra-individual change. We recommend introducing a latent growth curve model (LGCM) analysis, a method frequently applied to learning data but rarely used in cognitive training research. Such advanced analyses of the training phase allow identifying factors to be respected when designing effective tailor-made training interventions. To illustrate the proposed approach, a LGCM analysis using data of a 10-day working memory training study in younger and older adults is reported.
