Testing a self-determination theory intervention for motivating tobacco cessation: supporting autonomy and competence in a clinical trial.

A longitudinal randomized trial tested the self-determination theory (SDT) intervention and process model of health behavior change for tobacco cessation (N = 1006). Adult smokers were recruited for a study of smokers' health and were assigned to intensive treatment or community care. Participants were relatively poor and undereducated. Intervention patients perceived greater autonomy support and reported greater autonomous and competence motivations than did control patients. They also reported greater medication use and significantly greater abstinence. Structural equation modeling analyses confirmed the SDT process model in which perceived autonomy support led to increases in autonomous and competence motivations, which in turn led to greater cessation. The causal role of autonomy support in the internalization of autonomous motivation, perceived competence, and smoking cessation was supported.     

Who do students with mild disabilities nominate as cool in inclusive general education classrooms?

Examined the nominations that elementary students with mild disabilities made for peers they perceived as cool. The total sample was comprised of 948 students (496 girls, 452 boys) from the metropolitan Chicago area and North Carolina and included 107 (11.3%) students with mild disabilities. Overall, students with mild disabilities nominated prosocial and athletic peers who affiliate with students with mild disabilities. However, aggressive boys who are central in the social network were highly likely to view aggressive peers as cool. Results are discussed in relation to implications for social interventions for students with mild disabilities.     

School achievement strongly predicts midlife IQ

The relationship between measures of IQ and standardized school achievement tests is well established at around r ≈ 0.5 when the two are measured in close proximity. The current paper examined the stability of this correlation when comparing elementary school achievement (grades 3–8) and midlife IQ. Iowa Adoption Study participants who had standardized school achievement measures (ITBS) on file were given the WAIS-III. Mean age at IQ testing was 44.01 years (SD 6.65 years). The correlation between school achievement and WAIS-III FSIQ was r = 0.64, suggesting substantial life span stability in this relationship. Furthermore, elementary school achievement was substantially correlated with occupational status and household income at midlife. These findings suggest that standardized school achievement data is a useful measure of premorbid IQ.     

Is television traumatic? Dreams, stress, and media exposure in the aftermath of September 11, 2001

The terrorist attacks of September 11, 2001, were traumatic for people living throughout the United States. It has been suggested that people living far from the attacks experienced increased stress because of their exposure to the terrorist events via the media, particularly via television. Following a traumatic or stressful event, individuals may have dreams that reflect that experience. As part of a course on dreaming, individuals recorded their dreams both prior to and following the terrorist attacks of September 11, 2001. On September 12, these same individuals reported their activities and media exposure the previous day. Results revealed (a) changes in dream features following the attacks and (b) a strong relation between exposure to the events on television and changes in dream features after the attacks. Because of the study's within-subjects design, the results provide evidence for a direct association between television viewing and subsequent increases in stress and trauma.     

Parent–Infant Synchrony: Biological Foundations and Developmental Outcomes

ABSTRACT— Synchrony—a construct used across multiple fields to denote the temporal relationship between events—has been applied to the study of mother–infant interaction and is suggested here as a framework for the study of interpersonal relationships. Defined as the temporal coordination of micro-level social behavior, parent–infant synchrony is charted in its development across infancy from the initial consolidation of biological rhythms during pregnancy to the emergence of symbolic exchange between parent and child. Synchrony is shown to depend on physiological mechanisms supporting bond formation in mammals—particularly physiological oscillators and neuroendocrine systems such as those involving the hormone oxytocin. Developmental outcomes of the synchrony experience are observed in the domains of self-regulation, symbol use, and the capacity for empathy across childhood and adolescence. Specific disruptions to the parameters of synchrony that may be observed in various pathological conditions, such as prematurity or maternal affective disorder, are detailed. A time-based, micro-analytic behavioral approach to the study of human relationship may offer new insights on intersubjectivity across the lifespan.     

The relationship between adolescent depression and a history of sexual abuse

The purpose of this study was to examine the occurrence of depression among adolescents attending family planning clinics, and to determine the relationship among depression, a history of sexual abuse, and other risk behaviors. The sample consisted of 279 minority females. Results of the study indicated that 40 adolescents (14.3%) scored at or above a raw score of 77 for depression based on the Reynolds Adolescent Depression Scale (RADS). This suggests that these adolescents should be identified for further evaluation. Results of the Stepwise Linear Regression indicated that a history of sexual abuse was the most potent factor in predicting depression. These findings highlight the importance of screening concurrently for depression and a history of sexual abuse in family planning and other healthcare settings.     

A multilevel study of leadership, empowerment, and performance in teams

A multilevel model of leadership, empowerment, and performance was tested using a sample of 62 teams, 445 individual members, 62 team leaders, and 31 external managers from 31 stores of a Fortune 500 company. Leader-member exchange and leadership climate related differently to individual and team empowerment and interacted to influence individual empowerment. Also, several relationships were supported in more but not in less interdependent teams. Specifically, leader-member exchange related to individual performance partially through individual empowerment; leadership climate related to team performance partially through team empowerment; team empowerment moderated the relationship between individual empowerment and performance; and individual performance was positively related to team performance. Contributions to team leadership theory, research, and practices are discussed.     

A Comparison of Study Session Formats on Attendance and Quiz Performance in a College Course

We compared two formats for optional study sessions offered to students in a research methods course. Study sessions alternated between a game format (e.g., Behavioral Jeopardy) and a student-directed question and answer format, presented in counterbalanced order across different sections of the same course. The results of the alternating treatments design in Study 1 indicated that, despite improvements in quiz performance relative to baseline, there were no consistent differences between the two formats on attendance at the study sessions or on weekly quiz performance. Similar results were obtained in a systematic replication (Study 2) in which opportunities to respond to game questions were equated across study sessions.     

The motivating potential of teams: Test and extension of cross-level model of motivation in teams

Although individual- and team-level studies of motivational processes abound, very few have sought to link such phenomena across levels. Filling this gap, we build upon Chen and Kanfer’s (2006) multilevel theoretical model of motivation in teams, to advance and test a cross-level model of relationships between individual and team motivation and performance. Data from two samples of undergraduates performing simulated team tasks supported the direct and mediated cross-level relationships between team-level prior performance, efficacy, and action processes with individual-level self-efficacy, goal striving, and performance. The findings provide support for a multilevel, system-based formulation of motivation and performance in teams. Findings also contribute to the on-going debate on whether motivational processes account for performance once controlling for prior performance.
