Physical activity (PA) in youth tends to decline with increasing age, while sedentary behaviour including screen time (ST) increases. There are adolescents, however, whose PA and ST do not follow this pattern. The aim of this study is (i) to examine trajectories in PA and ST from grade 7–9 among students in Berlin, and (ii) to investigate the relationship of these trajectories with individual factors and school type. For the present analyses, changes in students’ PA and ST across three time points from 7th to 9th grade were assessed via self-report questionnaires. Positive and negative trajectories were defined for both PA (positive: increasing or consistently high, negative: decreasing or consistently low) and ST (vice versa). Multivariable logistic regression analyses were performed to identify possible predictors of PA and ST trajectories. In total, 2122 students were included (50.2% girls, mean age 12.5 (standard deviation 0.7) years). Compared to grade 7, less students of grade 9 fulfilled PA and ST recommendations (PA: 9.4% vs. 13.2%; ST: 19.4% vs. 25.0%). The positive PA trajectory included 44% of all students (63% boys), while the positive ST trajectory included 21% of all students (30% boys). Being a boy was significantly associated with a positive PA trajectory, while being a girl, having a high socioeconomic status, and attending a high school, were significantly associated with a positive ST trajectory. Different PA and ST trajectories among adolescents should be taken into account when implementing prevention programs for this target group.

This study investigated the relationship of a gap between the intent to be physically active and actual participation in physical activity (‘intention–behavior gap’) and self-efficacy for physical activity during childhood. A self-report questionnaire was used to collect information from 946 children from the fourth and sixth grades in Japan on self-efficacy, intention, and physical activity. Children with an intention–behavior gap (high intent–low activity or low intent–high activity) had higher self-efficacy scores than those with low intent and low activity (27.66 or 27.65 vs. 21.69; p < .001). They had lower self-efficacy scores than those with high intent and high activity (27.66 or 27.65 vs. 30.56; p < .001). Children with an intention–behavior gap had lower self-efficacy for physical activity than those who intended to be and were physically active. Such children may benefit from education interventions that focus on improving self-efficacy.

The relationship of openness-to-experience and mental health was investigated for 30 college women using Strupp and Hadley's 1977 tripartite model of mental health plus Holmes and Rahe's measure of recent stress. The set of mental health measures were employed in multiple regression analyses to predict self-report, behavioral, perceptual, and transactional measures of openness. Only the transactional measure of openness, defined as the ability to increase openness in a facultative situation, was significantly predicted by mental health.

Active Travel To School

Abstract Background: Little is known about the relationship of active travel to school (ATS) with physical activity (PA) and screen time (ST) by individual and parental characteristics among adolescents, especially in China. To address the research gap, this study aimed to explore the difference of sex, age, geographical location, parental occupation and education level in the relationship of ATS with PA and ST among students of grades 7-12 using cross-sectional data.Methods: In 13 cities of Hubei province, China, students from 39 public schools were recruited to engage in the survey. In total, 5898 students (response rate = 89.6%) were invited into this study. Participants were required to report their ATS (including its types), PA and ST as well as sociodemographic information using validated questionnaire. Descriptive analyses were used to report the information of all variables. Regression models were used to analyze the relationships of ATS and its types with PA and ST.Results: In a total of 4128 participants (boy: 50.9%; younger adolescents: 61.9%) included in the final analysis, the proportion of those with ATS was 47.3%. Regarding the types of ATS, walking accounted for over 30%, while cycling was 13.2%. Participants with ATS were more likely to have sufficient PA (OR = 1.26, 95% CI: 1.14-1.39), especially among boys, younger adolescents and those with lower parental education level. However, ATS was not associated with ST (OR = 0.94, 95% CI: 0.86-1.01). Participants with cycling had higher odds ratio of being physically active (OR for cycling = 1.47, 95% CI: 1.27-1.70; OR for walking = 1.18, 95% CI: 1.06-1.32). The association of ATS types with PA and ST differed by gender, age, geographical location and parental educational level as well as occupations.Conclusions: ATS may be a useful approach to increase PA among adolescents, but this should be explained by individual and parental characteristics.

The Relationship

Experiential avoidance (EA) has been connected to various behavioural indicators of psychological distress, implicated in the etiology and maintenance of psychological disorders, and is the target of prevalent psychological treatments. However, the reasons that individuals engage in dysfunctional EA are little understood. One hypothesis focuses on the preference for small, immediate rewards above larger, delayed rewards — in other words, impulsiveness. We examined the relationship of impulsiveness, measured both by self-report and behaviourally, to EA, while statistically controlling for possible confounding variables (i.e., intellectual functioning, gender, ethnicity), in a sample of normal undergraduate participants. Regression analyses suggest a significant relationship exists between EA and self-reported (but not behaviourally measured) impulsiveness. Exploratory analyses indicate nonplanning-type impulsiveness might be the best predictor of EA. Possible confounding variables did not account for a significant amount of variance within either model examined. Thus, support is provided for a theoretically proposed relationship within the Acceptance and Commitment Therapy model of psychopathology between EA and impulsiveness.

The purpose of this study was to examine the relationship between physical activity and creative behaviors. A random sample of 612 college students, ages 18-35, enrolled at a large Southeastern university, were recruited via an anonymous email invitation. Creative behaviors were assessed via two self-report questionnaires, includingthe Kaufman Domains of Creativity Scale (K-DOCS) and the Biographical Inventory of Creative Behaviors (BICB). Self-reported physical activity habits were assessed with the Physical Activity Vital Sign (PAVS) questionnaire. One-week test–retest reliability was established on 10% of the participants.Of the multiple regression analyses that were conducted to examine the hypothesized relation-ship, between physical activity and creative activities, physical activity participation did not meaningfully influence domain-general or domain-specific creative activities. Additional selected independent variables, such as degree of exercise enjoyment and academic major were statistically significantly associated with self-reported creative activities. This study serves to identify more inclusive, yet parsimonious research hypotheses to further scientific knowledge in this under-investigated area.

The relationships between sport involvement variables (participation and interest) and facets of children's morality (reasoning maturity and aggression tendencies) were investigated for 106 girls and boys in grades 4 through 7. Children responded to a sport involvement questionnaire, participated in a moral interview, and completed two self-report instruments designed to assess aggression tendencies in sport-specific and daily life contexts. Analyses revealed that boys' participation and interest in high contact sports and girls' participation in medium contact sports (the highest level of contact sport experience they reported) were positively correlated with less mature moral reasoning and greater tendencies to aggress. Regression analyses demonstrated that sport interest predicted reasoning maturity and aggression tendencies better than sport participation. Results and implications are discussed from a structural developmental perspective.

Abstract. Prosocial behavior is intended to benefit others rather than oneself and is positively linked to personality traits such as Agreeableness and Honesty-Humility, and usually negatively to the Dark Triad traits (i.e., Machiavellianism, narcissism, and psychopathy). However, a significant proportion of the research in this area is conducted solely on self-report measures of prosocial behavior. Therefore, the aim of this study was to investigate the relationship between prosociality and the basic (i.e., HEXACO) and dark personality traits, comparing their contribution in predicting both self-reported prosociality and prosocial behavior. Results of the hierarchical regression analyses showed that the Dark Triad traits explain prosociality and prosocial behavior above and beyond the HEXACO traits, emphasizing the importance of the Dark Triad in the personality space.

Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. The aim of this study was to assess the relationship of L-lactate concentrations measured using a Lactate Scout+ analyzer and a traditional lactate assay colorimetric kit. Blood samples were collected by venipuncture from 96 steers (Black or Red Angus × Hereford/Simmental and Black or Red Angus × Charolais; 247 ± 38.2 kg BW) prior to loading (LO1) and after 36 h of transport, and prior to reloading and after an additional 4 h of road transportation, and on d 1, 2, 3, 5, 14, and 28 after transport. The Lactate Scout+ analyzer strip was dipped in blood at the time of sampling, while blood samples were collected into sodium fluoride tubes for use in the colorimetric analysis. Pearson correlations were calculated to assess the strength of the relationship between the experimental methods for the quantification of L-lactate concentrations. The magnitude and direction of the correlation, and the level of statistical significance varied over the observed time points, ranging from r = −0.03 (p = 0.75; LO1) to r = 0.75 (p < 0.0001; d 3). The correlation for the pooled data was weak but statistically significant (r = 0.33, p < 0.0001). Based on the low magnitude of the correlation due to variability across sampling time points in this study, the Lactate Scout+ analyzer is not a suitable alternative to a lab-based assay (considered the gold standard) for measuring L-lactate in transported cattle.

Abstract Blood metabolites are used to assess a variety of animal conditions for veterinary diagnosis and research. Concentration of metabolites in blood can be measured using a commercially-available lab-based assay or in real-time using a handheld device developed to be more time- and cost-effective than the lab-based method. Lactate is a product of anaerobic glycolysis, used in animal research as an indicator of muscle fatigue. Therefore, it has been used as an indicator of cattle response to long distance transportation. The aim of this study was to assess the relationship of L-lactate concentrations measured using a Lactate Scout+ analyzer (Lactate Scout, EFK Diagnostics, Barleben, Germany) and a lactate assay colorimetric kit (Lactate Assay Kit, Cell Biolabs Inc., San Diego, CA). Blood samples were collected by venipuncture from 96 steers (245 ± 35.7 kg BW) prior to (L1) and after 36 h, and prior to and after an additional 4 h of road transportation, and on d 1, 2, 3, 5, 14, and 28 after transport. The Lactate Scout+ analyzer strip was dipped in blood at the time of sampling, while blood samples were collected into sodium fluoride tubes for use in colorimetric analysis. Pearson correlations were calculated to determine the relationship between the experimental methods for the quantification of L-lactate concentrations. The strengths and levels of statistical significance of the correlation varied over the observed time points, r = -0.03, P = 0.75 (L1) to r = 0.75, P = &lt; 0.0001 (d 3). The correlation for the pooled data was weak but statistically significant (r = 0.33, P &lt; 0.001). Based on the experimental results, the Lactate Scout+ analyzer is not a suitable alternative to a lab-based assay for measuring L-lactate in transported cattle, due to variability across sampling time points and weak correlation with the traditional enzymatic method.
