The Development of Aggression During Adolescence: Sex Differences in Trajectories of Physical and Social Aggression Among Youth in Rural Areas

To describe trajectories of aggressive behaviors for adolescents living in rural areas, we compared the patterns, timing and sex differences in development of physical and social aggression using five waves of data collected from youth in school surveys administered over 2.5 years. The sample (N = 5,151) was 50.0% female, 52.1% Caucasian and 38.2% African-American. Multilevel growth curve models showed that physical and social aggression followed curvilinear trajectories from ages 11 to 18, with increases in each type of aggression followed by subsequent declines. Physical aggression peaked around age 15; social aggression peaked around age 14. Boys consistently perpetrated more physical aggression than girls, but the trajectories were parallel. There were no sex differences in the perpetration of social aggression. Given the characteristics of the developmental trajectories observed, interventions with both boys and girls targeting physically and socially aggressive behaviors are needed in early adolescence to slow the development of aggression.     

Forgiveness and psychological adjustment following interpersonal transgressions: A longitudinal analysis

Forgiveness is often assumed to be adaptive for psychological adjustment following interpersonal transgressions. Three hundred and forty seven individuals who had experienced a recent interpersonal transgression were surveyed on four occasions over the course of six weeks. Forgiveness was assessed with scales measuring interpersonal avoidance and revenge motivation and psychological adjustment was assessed with scales measuring depression and rumination. Latent growth curve analyses showed that intraindividual changes in forgiveness were positively correlated with changes in adjustment. Latent difference score analyses indicated that adjustment predicted subsequent change in forgiveness, but that forgiveness did not predict subsequent change in adjustment. The results suggest that adjustment facilitates forgiveness, but not that forgiveness facilitates adjustment.     

Multiple trajectories of physical aggression among adolescent boys and girls

Latent growth mixture modeling was used to identify discrete patterns of physical aggression from Grades 7 to 11 among a sample of 1,877 youth. Four trajectory classes adequately explained the development of physical aggression in both boys and girls: Low/No Aggression; Persistent High Aggression; Desisting Aggression, characterized by decreasing risk throughout adolescence; and Adolescent Aggression, characterized by low early risk that increases until Grade 9, levels out, and then declines in late adolescence. Girls were less likely than boys were to be in any trajectory besides the Low/No Aggression trajectory. Parental supervision, deviant peer association, academic orientation, impulsivity, and emotional distress at Grade 7 were all strongly associated with trajectory class membership. These associations did not differ by gender. These findings strongly suggest that the processes involved in the development of physical aggression in adolescence operate similarly in boys and girls.

Form effects on the estimation of students' oral reading fluency using DIBELS

This study examined the effects of passage and presentation order on progress monitoring assessments of oral reading fluency in 134 second grade students. The students were randomly assigned to read six one-minute passages in one of six fixed orders over a seven week period. The passages had been developed to be comparable based on readability formulas. Estimates of oral reading fluency varied across the six stories (67.9 to 93.9), but not as a function of presentation order. These passage effects altered the shape of growth trajectories and affected estimates of linear growth rates, but were shown to be removed when forms were equated. Explicit equating is essential to the development of equivalent forms, which can vary in difficulty despite high correlations across forms and apparent equivalence through readability indices.     

Short-term effects of grade retention on the growth rate of Woodcock-Johnson III broad math and reading scores

We investigated the effects of grade retention in first grade on the growth of the Woodcock-Johnson broad mathematics and reading scores over three years using linear growth curve modeling on an academically at-risk sample. A large sample (n = 784) of first grade children who were at risk for retention was initially identified based on low literacy scores. Scores representing propensity for retention were constructed based on 72 variables collected in comprehensive baseline testing in first grade. We closely matched 97 pairs of retained and promoted children based on their propensity scores using optimal matching procedures. This procedure adjusted for baseline differences between the retained and promoted children. We found that grade retention decreased the growth rate of mathematical skills but had no significant effect on reading skills. In addition, several potential moderators of the effect of retention on growth of mathematical and reading skills were identified including limited English language proficiency and children's conduct problems.

The Pleasant Life, the Engaged Life, and the Meaningful Life: What about the Balanced Life?

Martin Seligman, in his very popular book Authentic Happiness (Seligman 2002), argued that authentic happiness is derived from three major sets of experiences in life, namely experiencing pleasantness regularly (the pleasant life), experiencing a high level of engagement in satisfying activities (the engaged life), and experiencing a sense of connectedness to a greater whole (the meaningful life). In this paper, we maintain that balance in life contributes significantly to subjective well-being. Balance contributes to subjective well-being because of the satisfaction limit that people can derive from a single life domain. People have to be involved in multiple domains to satisfy the full spectrum of human development needs. Different life domains tend to focus on different human developmental needs. More specifically, balance contributes to subjective well-being because subjective well-being can only be attained when both survival and growth needs are met. High levels of subjective well-being cannot be attained with satisfaction of basic needs or growth needs alone. Both needs have to be met to induce subjective well-being.     

Life Satisfaction is not a Balanced Estimator of the Good Life: Evidence from Reaction Time Measures and Self-Reported Emotions

A widespread belief in happiness research is that measures of life satisfaction capture the variety of an individual’s experiences along a single favorable—unfavorable dimension. The current article points to a possible violation of this assumption. With a combination of data and theory it argues that life satisfaction is not a balanced reflection of subjective experiences because the evaluation that drives judgments of life satisfaction is tilted towards pleasure and away from engagement. We postulate that feelings of pleasure are overrated in statements of life satisfaction, whereas feelings of engagement are underrepresented. Feelings of engagement and interest are further supposed to be indicators of personal growth. Measures of personal growth and life satisfaction should thus be unrelated. Empirical evidence for our model is provided by self-report and reaction time data from a Norwegian convenience sample (N = 30). Detection latencies for pleasant stimuli correlated significantly with life satisfaction but not with measures of personal growth. Life satisfaction correlated significantly with pleasant experiences, but not with engagement. Personal growth correlated significantly with feelings of engagement. Life satisfaction and personal growth were uncorrelated.
