Comparison of Self-Reported and Objectively Measured Sedentary Behavior and Physical Activity in Undergraduate Students

ABSTRACT

The aim of this study was to investigate differences between estimates of sedentary behavior and physical activity (PA) from the International Physical Activity Questionnaire (IPAQ) and accelerometry in undergraduate students. 91 students participated in the study. Sedentary behavior and PA were objectively measured by an accelerometer for 7 days and then self-reported with the IPAQ. Partial correlations were used to assess associations among PA variables and participant characteristics between the methods. Agreement was assessed via the Bland–Altman method. Correlation coefficients between self-reported and objectively measured PA ranged from 0.21 to 0.38 (p≤ 0.05 for all). A higher proportion of students were classified as meeting PA guidelines via self-report compared to objective measurements. Bland–Altman plots revealed acceptable agreement between methods, however, bias was evident for all PA intensities. Sex and lean body mass impacted these differences. Researchers should exercise caution when interpreting PA assessed via the IPAQ in undergraduate students.     

Sport development and physical activity promotion: An integrated model to enhance collaboration and understanding

As inactivity and obesity levels continue to rise, calls are being made for sport development action to be further directed towards capitalising on the value of community participation for health and social benefits. This paper seeks to highlight a current disconnect between physical activity and sport management research, and identify opportunities for collaboration. To date, the sport management literature has predominantly focused on sport as a form of entertainment with spectatorship outcomes, where professional codes are a commonly used setting of research inquiry. There has been less focus on organisational issues related to participation in sport and recreation. This is identified as a gap, given the current push towards increasing focus on sport and recreation promotion for community wellbeing. The present paper sought to examine physical activity and sport management research, to identify commonalities and potential for integration and co-operation. The outcome of this review is a conceptual framework, integrating socio-ecological models, taken from physical activity research, and sport development concepts derived from sport management theory. The proposed conceptual framework seeks to provide sport management researchers with direction in their efforts to promote participation in sport, recreation and physically active leisure domains, particularly for community wellbeing purposes. Furthermore, such direction may also enhance the capacity of researchers to capitalise on opportunities for collaboration and integration across domains of inquiry.     

CS–US interval determines the transition from overshadowing to potentiation with flavor compounds

The present series of five flavor aversion experiments with rat subjects examined compound conditioning at varying CS-US intervals. Using a taste-taste design, Experiments 1A and 1B demonstrated overshadowing at a 0-min CS-US interval and potentiation at a 120-min CS-US interval, and these effects occurred with both tastes of the compound. Experiment 2 showed that the aversion to a single element is reduced when the CS-US interval is increased to 120 min, but the aversion for a compound taste is not. Experiments 3A and 3B explored odor + taste compound conditioning; the results demonstrated odor potentiation across the trace interval and a transition from taste overshadowing to taste potentiation. Collectively, the data show that the change from overshadowing to potentiation was not due to changes in the aversions produced by compound conditioning but, instead, was due to a more rapid loss of conditionability across a trace interval prior to the US in single-element conditioning. These experiments suggest that following compound conditioning, the aversion to each element represents generalization decrement from the configured compound, but the designation of overshadowing or potentiation actually depends on the status of conditioning in the single-element control.     

Further Examination of a Curriculum-Based Value-Added Model for Teacher Preparation: Exploring the Role of Teachers’ Behavior on K–12 Student Learning

Multiple threats to validity and reliability exist when value-added models (VAMs) rely wholly on standardized assessments to measure the relationship between teachers and their K–12 students’ learning gains. Research on a curriculum-based VAM, built on evidence-based practices, continues to establish an explicit link between teacher candidates’ instruction and their K–12 students’ learning gains. Statistical tests of association were used to analyze measures of student learning and university supervisors’ ratings during classroom observations with a department instrument, the Narrative Observation Scale. Results from a sample of 23 teacher candidates revealed that (a) two measures of student learning were related and attributed to candidates’ instruction, and (b) 67.6% of the variance in the percentage of K–12 students meeting their specific learning objectives was accounted for by the teacher candidates’ mastery of specific classroom management behaviors. Limitations and directions for future research are discussed regarding continued efforts to refine a rational, curriculum-based VAM.     

Testosterone during pregnancy and gender role behavior of preschool children: a longitudinal,population study

Levels of testosterone (T) and sex hormone-binding globulin (SHBG) were measured in blood samples from pregnant women and related to gender role behavior in 342 male and 337 female offspring at the age of 3.5 years. Gender role behavior was assessed using the Pre-School Activities Inventory, a standardized measure on which a parent indicates the child's involvement with sex-typical toys, games, and activities. Levels of T, but not SHBG, related linearly to gender role behavior in preschool girls. Neither hormone related to gender role behavior in boys. Other factors, including the presence of older brothers or sisters in the home, parental adherence to traditional sex roles, the presence of a male partner in the home, and maternal education, did not relate to gender role behavior in this sample and did not account for the relation observed between T and behavior. Although other, unmeasured factors may explain the relation, the results suggest that normal variability in T levels prenatally may contribute to the development of individual differences in the gender role behavior of preschool girls.     

An Exploratory Evaluation of Conjoint Behavioral Consultation to Promote Collaboration Among Family,School, and Pediatric Systems: A Role for Pediatric School Psychologists

Pediatric school psychology is a relatively new subspecialty in the field; however, few specific, prescribed roles have been articulated, and fewer have yielded preliminary efficacy data. In this exploratory study, the acceptability and potential efficacy of conjoint behavioral consultation (CBC) as a model for linking families, schools, and pediatric settings to address concerns for children with medical issues were evaluated. Twenty-nine children, their parents, teachers, and consultants were involved in conjoint consultation, a model of cross-system collaboration to address shared concerns of medically referred children. In this structured indirect service delivery model, parents, teachers, and school psychology pediatric consultants worked collaboratively in interdisciplinary problem solving and joint decision making with extensive input regarding medical issues from a developmental pediatrician. Outcome measures included parent and teacher observations of child functioning across home and school settings as a result of consultation-mediated interventions and social validity indices assessing acceptability and consumer satisfaction. Results suggested that CBC is a socially valid procedure for addressing concerns of medically referred children across home and school systems. Both parents and teachers reported the consultation process to be highly acceptable. Preliminary effect size analyses of child outcomes, derived from uncontrolled case study designs, suggest generally positive effects across home and school, although limitations with the methodology preclude conclusive statements. Research is needed to determine the contexts and conditions under which the model is more or less effective using rigorous controlled trials.     

The Relationship between Student Perceptions of Instructor Power and Classroom Justice This manuscript was presented as part of the Top Paper Panel to the Instructional Practices Interest Group of the Eastern Communication Association at its annual meeting in Pittsburgh, 2005.

The study investigated the relationships between student perceptions of instructor power and classroom justice. Partial correlations controlling for student grade expectations indicated that student perceptions of their instructors’ use of coercive, legitimate, referent, and expert power were related to perceptions of fairness in the classroom. Student perceptions of instructor use of reward power were not related to perceptions of any type of classroom justice.     

Daughters' Perceptions of Communication with Their Fathers: The Role of Skill Similarity and Co-Orientation in Relationship Satisfaction

This study examines the communication skill similarity between fathers and daughters. Participants were 186 daughters who identified perceptions of both their own communication competence and their father's communication competence. Results indicated that perceived similarity was related to relational satisfaction and quantity of communication. Using the Family Communication Pattern (FCP) model, father-daughter relationship satisfaction and communication skill similarity varied depending on the family type (i.e., consensual, pluralistic, protective, laissez-faire).     

Improving the Museum Experiences of Children with Autism Spectrum Disorders and Their Families: An Exploratory Examination of Their Motivations and Needs and Using Web‐based Resources to Meet Them

Through a partnership with a local school, the Smithsonian Institution and the Information Policy and Access Center at the University of Maryland conducted an exploratory study to examine the motivations and needs of families visiting museums with children with Autism Spectrum Disorders (ASDs). This study represents one of the first undertakings to study visitors with ASDs, especially children, through a primarily qualitative data collection. Interest‐driven enjoyment emerged as a primary motivation, though to relax and to socialize outside of the family boundaries were not ranked as important motives for visiting museums. Children, who were directly interviewed, gave positive assessments of their museum experiences, while parents commented that challenges, both museum‐ and family‐related (crowds, loud noise, not feeling welcome, and a child's unpredictable behavior) surfaced in public settings like museums. Parents desired a “typical family outing” with their ASDs child, stating that manageable and safe environments helped families experience a museum.
