SALLIS, J. F., J. J. PROCHASKA, and W. C. TAYLOR. A review of correlates of physical activity of children and adolescents. Med. Sci. Sports Exerc., Vol. 32, No. 5, pp. 963‐975, 2000. Background: Understanding the factors that influence physical activity can aid the design of more effective interventions. Previous reviews of correlates of youth physical activity have produced conflicting results. Methods: A comprehensive review of correlates of physical activity was conducted, and semiquantitative results were summarized separately for children (ages 3‐12) and adolescents (ages 13‐18). The 108 studies evaluated 40 variables for children and 48 variables for adolescents. Results: About 60% of all reported associations with physical activity were statistically significant. Variables that were consistently associated with children’s physical activity were sex (male), parental overweight status, physical activity preferences, intention to be active, perceived barriers (inverse), previous physical activity, healthy diet, program/facility access, and time spent outdoors. Variables that were consistently associated with adolescents’ physical activity were sex (male), ethnicity (white), age (inverse), perceived activity competence, intentions, depression (inverse), previous physical activity, community sports, sensation seeking, sedentary after school and on weekends (inverse), parent support, support from others, sibling physical activity, direct help from parents, and opportunities to exercise. Conclusion: These consistently related variables should be confirmed in prospective

Pedagosko i psiholosko testiranje i procjenjivanje spadaju među najvažnije doprinose znanosti o ponasanju nasem drustvu i pružaju temeljna i znacajna poboljsanja u odnosu na ranije postupke. Iako se ne može ustvrditi da su svi testovi dovoljno usavrseni niti da su sva testiranja razborita i korisna, postoji velika kolicina informacija koje ukazuju na ucinkovitost kvalitetnih instrumenata u onim situacijama u kojima je njihovo koristenje potkrijepljeno validacijskim podacima. Pravilna upotreba testova može dovesti do boljih odluka o pojedincima i programima nego sto bi to bio slucaj bez njihovog koristenja, a također i ukazati na put za siri i pravedniji pristup obrazovanju i zaposljavanju. Međutim, losa upotreba testova može dovesti do zamjetne stete nanesene ispitanicima i drugim sudionicima u procesu donosenja odluka na temelju testovnih podataka. Cilj Standarda je promoviranje kvalitetne i eticne upotrebe testova te uspostavljanje osnovice za ocjenu kvalitete postupaka testiranja. Svrha objavljivanja Standarda je uspostavljanje kriterija za evaluaciju testova, provedbe testiranja i posljedica upotrebe testova. Iako bi evaluacija prikladnosti testa ili njegove primjene trebala ovisiti prvenstveno o strucnim misljenjima, Standardi pružaju okvir koji osigurava obuhvacanje svih relevantnih pitanja. Bilo bi poželjno da svi autori, sponzori, nakladnici i korisnici profesionalnih testova usvoje Standarde te da poticu druge da ih također prihvate.

Standards for educational and psychological testing

The purpose was to: 1) perform a systematic review of studies examining the relation between physical activity, fitness, and health in school-aged children and youth, and 2) make recommendations based on the findings. The systematic review was limited to 7 health indicators: high blood cholesterol, high blood pressure, the metabolic syndrome, obesity, low bone density, depression, and injuries. Literature searches were conducted using predefined keywords in 6 key databases. A total of 11,088 potential papers were identified. The abstracts and full-text articles of potentially relevant papers were screened to determine eligibility. Data was abstracted for 113 outcomes from the 86 eligible papers. The evidence was graded for each health outcome using established criteria based on the quantity and quality of studies and strength of effect. The volume, intensity, and type of physical activity were considered. Physical activity was associated with numerous health benefits. The dose-response relations observed in observational studies indicate that the more physical activity, the greater the health benefit. Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters (e.g., obese). To achieve substantive health benefits, the physical activity should be of at least a moderate intensity. Vigorous intensity activities may provide even greater benefit. Aerobic-based activities had the greatest health benefit, other than for bone health, in which case high-impact weight bearing activities were required. The following recommendations were made: 1) Children and youth 5-17 years of age should accumulate an average of at least 60 minutes per day and up to several hours of at least moderate intensity physical activity. Some of the health benefits can be achieved through an average of 30 minutes per day. [Level 2, Grade A]. 2) More vigorous intensity activities should be incorporated or added when possible, including activities that strengthen muscle and bone [Level 3, Grade B]. 3) Aerobic activities should make up the majority of the physical activity. Muscle and bone strengthening activities should be incorporated on at least 3 days of the week [Level 2, Grade A].

Evaluating the Factorial Structure of the Revised Causal Dimension Scale in Adolescents

Physical Activity Questionnaire for Older Children

The purpose of this investigation was to determine the relationship between cognitive appraisal and self-reported affect during challenging physical activity by 55 adults (16 females, 39 males) with physical disabilities. Eleven cognitive appraisals related to perceived challenge in physical activity plus positive and negative affect experienced in a recent challenging physical activity were assessed in an interview. The data indicated that perceived challenge was characterized by higher levels of positive affect (M=4.03, SD=.71) compared to negative affect (M=1.54, SD=.61). Correlational analyses revealed that the appraisals of fitness and health, learning skills, demonstrating competence, effort, social approval, task value, and external control were all significantly related to positive affect. A regression analysis for positive affect revealed that a two-term equation using task value and social approval could account for 39% of the variance. No appraisals were significantly related to negative affect.

OBJECTIVE Transition to university is a vulnerable period for discontinuing regular physical activity that can have implications for students' physical and psychological health. Accordingly, it is imperative to find and implement cost and time-effective interventions to mitigate the consequences of this transition. Intervention research has shown mental contrasting is an effective means of promoting various health-enhancing behaviors including physical activity. However, the efficacy of this intervention approach may be bolstered by targeting affective judgments (e.g., enjoyable-unenjoyable), which exert greater influence on physical activity behaviors compared to health-related instrumental judgments (e.g., useful-useless). The purpose of this study was to compare the relative efficacy of a mental contrasting intervention that targeted affective judgments associated with physical activity, in relation to a mental contrasting intervention that targeted instrumental judgments, and a "standard" mental contrasting intervention (with no modifications). METHOD Using a 3-arm parallel randomized controlled trial design (ClinicalTrials.gov Number NCT02615821), 110 insufficiently active, female, university students were randomly assigned to an affective, instrumental, or standard mental contrasting intervention following simple randomization procedures. Assessments were conducted at baseline and 4 weeks postintervention. RESULTS Participants in the affective mental contrasting condition displayed higher levels of moderate-to-vigorous physical activity than those in the instrumental or standard comparison conditions, F(2, 90) = 3.14, p < .05, ηp2 = 0.065. CONCLUSION Overall, affective mental contrasting has the potential to represent a low-cost and time-efficient intervention that may help insufficiently active, female students increase activity or attenuate declining levels of moderate-to-vigorous physical activity that occurs during university.
