Are park proximity and park features related to park use and park-based physical activity among adults? Variations by multiple socio-demographic characteristics.

BACKGROUND: Parks are valuable resources for physical activity (PA) given their widespread availability and low cost to maintain and use. Both proximity to parks and the availability of particular features are important correlates of PA. However, few studies have explored multiple measures of proximity simultaneously or the specific facilities associated with park use and park-based PA among adults, let alone differences across socio-demographic characteristics. The purpose of this study was to examine associations between park proximity and park facilities and adults' park use and park-based PA, while also exploring differences by gender, age, race, and income. METHODS: Data on monthly park use and weekly amount of PA undertaken in parks were collected via a mail survey of adults from randomly-selected households (n = 893) in Kansas City, Missouri (KCMO) in 2010-2011. Three measures of park proximity were calculated within 1 mile of participating households: distance to the closest park, number of parks, and total park area. All parks in KCMO were audited using the Community Park Audit Tool to determine the availability of 14 park facilities within 1 mile of each participant (e.g., trail, playground, tennis court). Multilevel logistic regression was used to examine the relationship between each of park use and park-based PA and 1) three measures of park proximity, and 2) the availability of 14 park facilities within 1 mile of participants. Separate analyses were conducted by gender, age, race, and income, while controlling for all socio-demographic characteristics and BMI. RESULTS: Across all sub-samples, distance to the closest park was not significantly related to either park use or park-based PA. However, numerous significant associations were found for the relationship of number of parks and amount of park space within 1 mile with both outcomes. As well, diverse facilities were associated with park use and park-based PA. For both park proximity and facilities, the significant relationships varied widely across gender, age, race, and income groups. CONCLUSIONS: Both park proximity and park facilities are related to park use and park-based PA. Understanding how such associations vary across demographic groups is important in planning for activity-friendly parks that are responsive to the needs of neighborhood residents.

Exploring the distribution of park availability, features, and quality across Kansas City, Missouri by income and race/ethnicity: an environmental justice investigation.

BACKGROUND: Parks are key community assets for physical activity, but some evidence suggests these resources are not equitably distributed. PURPOSE: This study examined disparities by income and race/ethnicity in the availability, features, and quality of parks across Kansas City, Missouri. METHODS: All parks and census tracts (CTs) were mapped using geographical information systems, and park features and quality were determined via audits. Multivariate analyses of covariance analyzed differences in park availability, features, and quality across low-, medium-, and high-income and race/ethnicity CT tertiles. RESULTS: Low-income CTs contained significantly more parks, but also had fewer parks with playgrounds and more quality concerns per park. High minority CTs had more parks with basketball courts, but fewer parks with trails. Medium-income CTs contained more aesthetic features per park. CONCLUSIONS: Future research should examine policies that contribute to and that might rectify disparities in park features and quality, especially in low-income and high minority areas.

Teaching children with autism to respond to disguised mands.

Children with autism spectrum disorder (ASD) often have difficulty inferring the private events of others, including private verbal behavior (e.g., thoughts), private emotional responses, and private establishing operations, often referred to as "perspective taking" by the general psychology community. Children with ASD also have difficulty responding to disguised mands. Skinner's description of the "disguised mand" is verbal behavior wherein the speaker's mand directly describes neither its reinforcer nor the corresponding establishing operations. Appropriate responding to disguised mands is required for successful social interaction, making it a social skill worth teaching to children with ASD. We used a nonconcurrent multiple baseline across participants design to investigate the effects of a multiple exemplar training package consisting of rules, role play, and feedback for teaching three boys with ASD to respond to disguised mands. The intervention was effective and generalization to novel disguised mands and people was observed.

Teaching children with autism to tell socially appropriate lies.

This study used a nonconcurrent multiple baseline across participants design to evaluate the use of rules, role-play, and feedback for teaching 3 children with autism spectrum disorder to tell socially appropriate lies when (a) presented with an undesired gift and (b) someone's appearance changed in an undesired way. The intervention was effective in teaching use of socially appropriate lies, and generalization to untrained people and gifts or appearances was observed.

A systematic replication of teaching children with autism to respond appropriately to lures from strangers.

We evaluated the effects of behavioral skills training in the home for teaching children with autism to abstain from going with strangers and immediately inform a familiar adult of the stranger's attempt to lure them in the natural environment. All participants learned to respond correctly to lures in the home and demonstrated concomitant changes in untrained natural settings. In situ training and an added incentive were necessary for 1 participant.

Association of street connectivity and road traffic speed with park usage and park-based physical activity.

PURPOSE: The purpose of this study was to examine associations between street connectivity and road traffic speed and neighborhood residents' use of parks and park-based physical activity. DESIGN: Cross-sectional. SETTING: Kansas City, Missouri. SUBJECTS: Participants were 893 adults from randomly selected households. MEASURES: Both self-reported park use and park-based physical activity were dichotomized as some versus none. Intersection density was calculated around each participant, and network analysis was used to determine whether participants had to travel on or cross a road with traffic speed greater than 35 miles per hour (mph) to reach the closest park. ANALYSIS: Multilevel logistic regression examined the association between intersection density and traffic speed wit park use and park-based physical activity. RESULTS: Compared to those in the lowest intersection density quartile, participants in the third and fourth quartiles were more likely to use parks and to engage in physical activity in parks (odds ratio [OR] = 1.76-2.34; all p < .05). Likewise, compared to those who had a high-speed road on their way to the closest park, participants with slower traffic routes to parks were more likely to use the parks (OR = 1.47; 95% confidence interval [CI] = 1.05-1.92). CONCLUSION: In addition to park proximity and the design of park features, ensuring direct and safe access to parks through street network design and traffic speed reduction strategies may be key to facilitating park-related physical activity.

Planning for health: a community-based spatial analysis of park availability and chronic disease across the lifespan.

The purpose of this study was to explore the spatial relationship between park availability and chronic health conditions (CHCs) across age groups in Kansas City, MO. Multinomial logistic regression examined the association between having a park within one-half mile from home and the likelihood of having 0, 1, or 2 or more CHCs. Among respondents aged 40-59, those without a park within one-half mile from home were more than twice as likely to have 2 or more CHCs compared to respondents that had a park nearby. Parks may be an important protective factor for chronic diseases, especially among middle-aged adults among whom access to neighborhood recreational environments may be particularly important.

Teaching children with autism to seek help when lost in public.

Children with autism may not develop safety skills (e.g., help-seeking behaviors) without explicit teaching. One potentially hazardous situation is when a child with autism becomes separated from caregivers in a retail establishment or other public setting. The purpose of this study was to evaluate a treatment package (rules, role playing, and praise) delivered in the natural environment for teaching 3 boys with autism to seek assistance from store employees when they became lost. Treatment was effective, and help-seeking behaviors generalized to untrained stores for all participants.

A review of research on procedures for teaching safety skills to persons with developmental disabilities.

Safety skills are an important but often neglected area of training for persons with developmental disabilities (DD). The present study reviewed the literature on teaching safety skills to persons with DD. Safety skills involve a variety of behaviors such as knowing how to cross the street or what to do in case of a house fire. A number of studies have been conducted on teaching these skills to individuals with DD. The studies reviewed have varying degrees of success and demonstrate varying degrees of generalization, but the general finding has been that prompting, reinforcement, and role-playing are effective teaching procedures across a variety of participants, skills, and settings.

Comparison of data-collection methods in a behavioral intervention program for children with pervasive developmental disorders: a replication.

Cummings and Carr (2009) compared two methods of data collection in a behavioral intervention program for children with pervasive developmental disorders: collecting data on all trials versus only the first trial in a session. Results showed that basing a child's progress on first-trial data resulted in identifying mastery-level responding slightly sooner, whereas determining mastery based on all trials resulted in slightly better skill maintenance. In the current replication, no such differences in indication of mastery or maintenance were observed when data were collected on all trials or the first trial.
