Purpose. To examine whether the stages of change of exercise adoption appropriately address strenuous, moderate, and mild intensities of physical activity. Design and Setting. Secondary analysis of four data sets investigating transtheoretical model (TTM) constructs for exercise adoption. Subjects. Four samples of differing age groups (adolescents, n = 400; college students, n = 240; adults, n = 346; seniors, n = 504). Measures. Stage of change algorithm for exercise adoption and self-reported physical activity. Results. Multivariate analysis of variance (MANOVA) results showed that stages of change were distinguished by strenuous and moderate but not mild exercise in the adolescent, college student, and adult sample. In the senior sample, stage differences were found in the frequency of exercising (equivalent for moderate to strenuous exercise) and the frequency of walking (equivalent for mild exercise). Bivariate correlation coefficients as well as sensitivity, specificity, and related quality indices decreased respectively from strenuous to moderate to mild exercise and from exercising to walking. Conclusions. Results provide additional support for the construct validity of the stages of change for strenuous and moderate intensities of physical activity. Development of a new stage assessment instrument for mild intensities of physical activity is recommended. Limitations include use of a different validation measure of exercise behavior in the senior sample.

Short Term Effects

We evaluated a three-level incentive program to promote regular, moderate physical activity among employees working in a federal agency. The objective was to assess the short-term effects of the intervention by examining the stages people go through as they attempt to make permanent changes in physical activity. Indicators of the process by which changes in physical activity take place were based on a modified version of the Transtheoretical Model of Behavior. A one-group pretest/posttest design was used to ascertain which of the stages the 1,192 participants were in both before and after the intervention. Analysis indicated that, of the 1,192 participants, 6.5% regressed one or more stages, 30.3% did not regress or progress from one stage to another, 27.7% remained in the maintenance stage, and 35.4% progressed one (21.1%) or more (14.3%) stages during the 50-day intervention. Among those who progressed, the most common change was from preparation to late preparation (20.8%) and from late preparation to action (19.4%). Findings reinforce the notion that the stages of change concept can serve as indicators of the change process which, in turn, can be used as evidence of the short-term effectiveness of interventions. Findings also indicate this type of intervention holds promise for increasing physical activity among willing participants of a worksite population.

Web Based

A high proportion of individuals with disabilities remain physically inactive. Therefore, this study (web-based survey) investigated the relationships between the Transtheoretical Model (TTM) and physical activity among 224 adults with physical disabilities (M age = 45.4 years, SD = 10.78, females = 71%). Additionally, the most important TTM predictors of the stages of change and physical activity were examined. Standardized self-report scales of the TTM constructs and physical activity were completed. The study findings supported the theorized relationships between the TTM constructs and physical activity. The behavioral and cognitive processes of change distinguished the stages of change. These two constructs and self-efficacy mostly predicted physical activity (R2total = .18). The assessment methodology of the TTM constructs needs to be revisited.

The article contains the results of adaptation and standardization of Russian version of M. Kernis – A. Paradise “The Contingent Self-Esteem Scale” received the translated title “The External Determinants of Self-Attitude Scale”. This scale includes 15 items and is aimed to measure reactivity of self-attitude in relation to external (situational) determinants. The study sample consisted of 440 participants (301 females, 139 males, with a mean age of 18,9 years). The Russian-language version of the technique was verified in terms of internal consistency (Cronbach’s alpha is 0,819), test-retest reliability (after two weeks the Spearman correlation coefficient is 0,805 p<0,01, after four weeks it is 0,782, p<0,01), discriminative ability (Spearman correlation coefficients range from 0,411 to 0,756, p<0,01), external and construct validity. Standardization information is presented as a table for interpretation raw data into stens. The results prove that “The External Determinants of Self-Attitude Scale” is a convenient psychological diagnostic tool and has all the necessary psychometric qualities. Further research steps are associated with standardization within other age groups and refinement of evidence of external and construct validity.

Accurately measuring children’s physical activity and their sedentary behavior is challenging. The present study compared 189 parental responses to a questionnaire surveying physical activity and sedentary behavior of children aged 6–14 years, to accelerometer outputs and time activity diaries for the same group. Responses were analyzed taking age, sex and maternal education into account. Correlation coefficients between questionnaire reports and accelerometer-based physical activity across all age groups were acceptable (up to r = .55). Yet, adjustment for age markedly attenuated these associations, suggesting concomitant influences of biological and behavioral processes linked to age. The comparisons of general time indications in the questionnaire with 24h-diary records suggested that parents tended to under- and over-report single activities, possibly due to social desirability. We conclude that physical activity questionnaires need to be designed for specific age groups and be administered in combination with objective measurements.

Background: A common hypothesis is that crime is a major barrier to physical activity, but research does not consistently support this assumption. This article advances research on crime-related safety and physical activity by developing a multilevel conceptual framework and reliable measures applicable across age groups. Methods: Criminologists and physical activity researchers collaborated to develop a conceptual framework. Survey development involved qualitative data collection and resulted in 155 items and 26 scales. Intraclass correlation coefficients (ICCs) were computed to assess test–retest reliability in a subsample of participants (N = 176). Analyses were conducted separately by age groups. Results: Test–retest reliability for most scales (63 of 104 ICCs across 4 age groups) was “excellent” or “good” (ICC ≥ .60) and only 18 ICCs were “poor” (ICC < .40). Reliability varied by age group. Adolescents (aged 12–17 y) had ICCs above the .40 threshold for 21 of 26 scales (81%). Young adults (aged 18–39 y) and middle-aged adults (aged 40–65 y) had ICCs above .40 for 24 (92%) and 23 (88%) scales, respectively. Older adults (aged 66 y and older) had ICCs above .40 for 18 of 26 scales (69%). Conclusions: The conceptual framework and reliable measures can be used to clarify the inconclusive relationships between crime-related safety and physical activity.
