How Do Racial/Ethnic Groups Differ in Their Use of Neighborhood Parks? Findings from the National Study of Neighborhood Parks.

The current study examined racial/ethnic differences in use of parks and park facilities and features and self-reported park use and perceptions. We conducted observations in a nationally representative sample of 193 neighborhood parks in 27 US cities over a 1-week period between April and August of 2016 using the System of Observing Play and Recreation in Communities (SOPARC). To determine the propensity of different racial/ethnic groups to use parks relative to expectation based on their representation in the surrounding neighborhood, we calculated the percentages of park users of each race/ethnicity and compared these to the percentages of racial/ethnic groups residing in the neighborhood within a 1-mile radius of the park based on 2010 U.S. Census data. In the same parks, we administered an intercept survey to assess park users' self-reported use and perceptions of the park (N = 1872). We examined racial/ethnic differences in self-reported use and perceptions of parks using GEE models that adjusted for several individual- and park-level covariates. Hispanics comprised a disproportionate percentage of observed park users. Racial/ethnic groups generally did not differ in their self-reported park use and perceptions, except for the social context of park visits. In adjusted models, Hispanics had significantly higher odds of visiting with a child family member (OR = 1.44) and lower odds of visiting alone than non-Hispanic whites (OR = .55). Findings highlight Hispanics' greater propensity to use parks and indicate that parks may serve a communal purpose for Hispanics that they do not serve for other racial/ethnic groups.

Park Use in Low-Income Urban Neighborhoods: Who Uses the Parks and Why?

We examined individual and environmental influences on park use among residents of two low-income predominantly African American neighborhoods to identify determinants of park use in lower-income urban neighborhoods. We analyzed data from interviews of 1003 individuals randomly selected from the neighborhoods, systematic observations of neighborhood parks, and police-recorded crime incidence within a .5-mi buffer around each park. Most participants (82.4%) had previously visited a neighborhood park, and nearly half (46.2%) had visited one in the past month. However, only 8.5% of participants were aware of their closest park. Compared with the parks closest to home, parks that participants reported visiting most were larger and had more amenities and features and fewer incivilities and reported crimes of a serious nature. Park use among residents of lower-income neighborhoods may be increased by offering more amenities and features and ensuring the presence of a well-appointed park within easy walking distance of residents' homes.

Attitudes and Barriers to Healthy Diet and Physical Activity: A Latent Profile Analysis.

Healthy diet and physical activity (PA) prevent and reduce chronic disease. Social cognitive theory delineates multiple attitudes and barriers that influence these behaviors. Understanding covariation in these attitudes and barriers is complex. We examined whether individuals could be grouped into a small number of categories that are easier to study. Interviews were conducted with 982 adults from two low-income, predominantly African American neighborhoods in the same city. Social cognitive constructs, including self-efficacy, social norms, and internal and external barriers to diet and exercise, and walking were self-reported. We measured moderate to vigorous physical activity with accelerometers and diet with 24-hour recalls. We conducted a latent profile analysis of attitudes and barriers to diet and PA and identified four classes: (a) moderate diet and negative exercise attitudes, where participants were roughly average on dietary attitudes but reported exercise-related challenges, including lower social support, outcome expectancies, physical functioning, and self-efficacy; (b) few barriers and benefits of healthy diet and exercise, where participants reported fewer barriers and lower outcome expectancies for diet and PA; (c) moderate overall attitudes, where participants had average scores on most indicators but below-average exercise self-efficacy and slightly more exercise barriers; and (d) positive overall attitudes, characterized by more positive attitudes toward both diet and PA across most domains, particularly regarding self-efficacy to overcome exercise barriers. These profiles could inform efforts to tailor individual-level interventions for diet and PA of persons at high risk of chronic diseases.

Does where you shop or who you are predict what you eat?: The role of stores and individual characteristics in dietary intake.

Interventions to address diet, a modifiable risk factor for diabetes, cancer, and cardiovascular disease, have increasingly emphasized the influence of the physical environment on diet, while more traditional approaches have focused on individual characteristics. We examined environmental and individual influences on diet to understand the role of both. Household interviews were conducted in 2011 with 1372 individuals randomly selected from two low-income, predominantly African American neighborhoods in Pittsburgh, PA. Participants reported their sociodemographic characteristics, food shopping behavior, and dietary intake. Both food shopping frequency at different types of food stores and sociodemographic characteristics showed significant associations with diet in adjusted regression models. More frequent shopping at convenience and neighborhood stores and being younger, male, without a college degree, and receiving SNAP benefits were associated with greater intake of sugar-sweetened beverages (SSBs), added sugars, and discretionary fats. Being older, male, and having a college degree were associated with greater intake of fruits and vegetables. However, while food shopping behavior and sociodemographic characteristics accounted for similar amounts of nonoverlapping variance in fruit and vegetable intake, food shopping behavior accounted for much less variance, and little unique variance, in SSBs, added sugars, and discretionary fats in models with sociodemographic characteristics. The current study reinforces the need for policies and interventions at both the environmental and individual levels to improve diet in food desert residents. Individual interventions to address food choices associated with certain sociodemographic characteristics might be particularly important for curbing intake of SSBs, added sugars, and discretionary fats.

Measurement invariance across administration mode: Examining the Posttraumatic Stress Disorder (PTSD) Checklist.

The Posttraumatic Stress Disorder (PTSD) Checklist (PCL) is commonly used to screen for PTSD in clinical and research contexts. While the PCL is utilized within numerous settings and populations, research has not yet established the extent to which individuals respond similarly across different modes of administration. The use of both telephone and web survey administration modes has numerous potential benefits, including data quality improvement, but may introduce an additional source of measurement error. The current study examined the psychometric properties, including factor structure and measurement invariance, of the PCL across telephone and web administration modes among 455 wounded, ill, or injured airmen who were medically retired or undergoing evaluation for disability caused by injuries and illnesses of a physical or psychological nature. Findings suggest the properties of the PCL were invariant with regard to the mode of administration, such that the overall scale structure and size of the loadings were similar across groups. Corrections were applied to the computation of probable PTSD diagnosis to account for partial scalar invariance. The lack of complete invariance did not affect probable PTSD diagnosis. Finally, differences in latent means across the telephone and web group were nonsignificant and modest in magnitude. These results indicate that although the PCL only achieved partial scalar invariance across administration modes, the practical impact of this difference on rates of probable PTSD is negligible. The practical benefits of administering the PCL over the telephone and on the web do not appear to be outweighed by the potential cost of additional measurement error. (PsycINFO Database Record

Where do food desert residents buy most of their junk food? Supermarkets.

OBJECTIVE: To examine where residents in an area with limited access to healthy foods (an urban food desert) purchased healthier and less healthy foods. DESIGN: Food shopping receipts were collected over a one-week period in 2013. These were analysed to describe where residents shopped for food and what types of food they bought. SETTING: Two low-income, predominantly African-American neighbourhoods with limited access to healthy foods in Pittsburgh, PA, USA. SUBJECTS: Two hundred and ninety-three households in which the primary food shoppers were predominantly female (77·8 %) and non-Hispanic black (91·1 %) adults. RESULTS: Full-service supermarkets were by far the most common food retail outlet from which food receipts were returned and accounted for a much larger proportion (57·4 %) of food and beverage expenditures, both healthy and unhealthy, than other food retail outlets. Although patronized less frequently, convenience stores were notable purveyors of unhealthy foods. CONCLUSIONS: Findings highlight the need to implement policies that can help to decrease unhealthy food purchases in full-service supermarkets and convenience stores and increase healthy food purchases in convenience stores.

Is cohesion within military units associated with post-deployment behavioral and mental health outcomes?

PURPOSE: Prior studies suggest that cohesion among members of military units has a positive impact on behavioral and mental health sequelae of combat deployment. However, these studies have not distinguished variation in cohesion across units from variation in perception of cohesion across individuals within units. METHODS: A sample of U.S. Marines was assessed before and after deployment to Iraq or Afghanistan in 2010 or 2011. Within-group centering was used to distinguish unit-level from individual-level associations of cohesion with four behavioral and mental health outcomes assessed after deployment: alcohol misuse, violation of the Uniform Code of Military Justice (UCMJ), probable posttraumatic stress disorder (PTSD) and a positive screen for depression. RESULTS: Unit-level cohesion is associated positively with alcohol misuse (OR=1.86, 95% CI 1.05-3.29) and negatively with UCMJ violations (OR=0.41, 95% CI 0.20-0.83) but not with probable PTSD (OR=1.00, 95% CI 0.60-1.6) or a positive screen for depression (OR=1.00 95% CI 0.58-1.72). Lower perception of cohesion relative to the other members of the same unit is associated with higher likelihood of UCMJ violations, probable PTSD and a positive screen for depression. LIMITATIONS: Data on all members of the studied units were not available. CONCLUSIONS: Distinguishing unit-level from individual-level variation in cohesion among military unit members reveals more varied associations with behavioral and mental health outcomes of deployment than have been reported in previous studies, in which these levels have been collapsed. Associations between individual-level variation in cohesion and mental health outcomes may result from pre-existing traits related to both perception of cohesion and risk for psychiatric disorders.

Longitudinal Associations Among Pain, Posttraumatic Stress Disorder Symptoms, and Stress Appraisals.

Comorbidity of posttraumatic stress disorder (PTSD) and pain is well documented, but the mechanisms underlying their comorbidity are not well understood. Cross-lagged regression models were estimated with 3 waves of longitudinal data to examine the reciprocal associations between PTSD symptom severity, as measured by the Clinician-Administered PTSD Scale (CAPS), and pain, as measured by a brief self-report measure of pain called the PEG (pain intensity [P], interference with enjoyment of life [E], and interference with general activity [G]). We evaluated stress appraisals as a mediator of these associations in a sample of low-income, underserved patients with PTSD (N = 355) at federally qualified health centers in a northeastern metropolitan area. Increases in PTSD symptom severity between baseline and 6-month and 6- and 12-month assessments were independently predicted by higher levels of pain (ß = .14 for both lags) and appraisals of life stress as uncontrollable (ß = .15 for both lags). Stress appraisals, however, did not mediate these associations, and PTSD symptom severity did not predict change in pain. Thus, the results did not support the role of stress appraisals as a mechanism underlying the associations between pain and PTSD.

Diet And Perceptions Change With Supermarket Introduction In A Food Desert, But Not Because Of Supermarket Use.

Placing full-service supermarkets in food deserts--areas with limited access to healthy food--has been promoted as a way to reduce inequalities in access to healthy food, improve diet, and reduce the risk of obesity. However, previous studies provide scant evidence of such impacts. We surveyed households in two Pittsburgh, Pennsylvania, neighborhoods in 2011 and 2014, one of which received a new supermarket in 2013. Comparing trends in the two neighborhoods, we obtained evidence of multiple positive impacts from new supermarket placement. In the new supermarket neighborhood we found net positive changes in overall dietary quality; average daily intakes of kilocalories and added sugars; and percentage of kilocalories from solid fats, added sugars, and alcohol. However, the only positive outcome in the recipient neighborhood specifically associated with regular use of the new supermarket was improved perceived access to healthy food. We did not observe differential improvement between the neighborhoods in fruit and vegetable intake, whole grain consumption, or body mass index. Incentivizing supermarkets to locate in food deserts is appropriate. However, efforts should proceed with caution, until the mechanisms by which the stores affect diet and their ability to influence weight status are better understood.

Prevalence of mental health problems among Iraq and Afghanistan veterans who have and have not received VA services.

OBJECTIVE: Roughly half of veterans who served in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) have not received services from the Veterans Health Administration (VHA). This study assessed probable posttraumatic stress disorder (PTSD) and depression among OEF/OIF veterans by receipt of VHA services. METHODS: In 2010 a mixed-mode survey assessing symptoms and VHA services utilization was fielded in a random sample of 913 New York State OEF/OIF veterans. RESULTS: Probable PTSD and depression were roughly three times more common among veterans who had received VHA services (N=537) (PTSD, 23%; depression, 21%) than those who had not (N=376) (PTSD, 6%; depression, 8%). CONCLUSIONS: Studies of veterans receiving VHA services likely overstate the prevalence of mental health problems among the broader OEF/OIF veteran population. However, many veterans with mental health problems are not receiving VHA services. Policies that improve outreach to this population may improve health outcomes.

The psychometric development and initial validation of the DCI-A short form for adolescent therapeutic community treatment process.

The 5-factor client-report Dimensions of Change in Therapeutic Communities Treatment Instrument-Adolescent (DCI-A) was developed to assess adolescent substance abuse treatment process in the therapeutic community (TC). The goal of this study was to use bifactor modeling to derive a unidimensional DCI-A short-form (DCI-A-SF) that would represent content from the original DCI-A factors. Data are from 442 adolescents receiving treatment at one of seven residential TC programs. Bifactor analyses suggested selection of seven DCI-A items to comprise the short form. Three items are from the treatment motivation factor, and one item was selected from each of the remaining four factors. Confirmatory factor analysis suggested that the 7-item DCI-A-SF is strongly unidimensional, and unidimensional IRT analysis of the items indicated good internal consistency. A structural equation model that demonstrates the mediating relationship of DCI-A-SF with other measures, including demographic and pre-treatment characteristics, and subsequent treatment completion, provides preliminary evidence of internal validity.

Integrating primary care into community behavioral health settings: programs and early implementation experiences.

OBJECTIVE: This article describes the characteristics and early implementation experiences of community behavioral health agencies that received Primary and Behavioral Health Care Integration (PBHCI) grants from the Substance Abuse and Mental Health Services Administration to integrate primary care into programs for adults with serious mental illness. METHODS: Data were collected from 56 programs, across 26 states, that received PBHCI grants in 2009 (N=13) or 2010 (N=43). The authors systematically extracted quantitative and qualitative information about program characteristics from grantee proposals and semistructured telephone interviews with core program staff. Quarterly reports submitted by grantees were coded to identify barriers to implementing integrated care. RESULTS: Grantees shared core features required by the grant but varied widely in terms of characteristics of the organization, such as size and location, and in the way services were integrated, such as through partnerships with a primary care agency. Barriers to program implementation at start-up included difficulty recruiting and retaining qualified staff and issues related to data collection and use of electronic health records, licensing and approvals, and physical space. By the end of the first year, some problems, such as space issues, were largely resolved, but other issues, including problems with staffing and data collection, remained. New challenges, such as patient recruitment, had emerged. CONCLUSIONS: Early implementation experiences of PBHCI grantees may inform other programs that seek to integrate primary care into behavioral health settings as part of new, large-scale government initiatives, such as specialty mental health homes.

Protective effects of maternal and peer support on depressive symptoms during adolescence.

The current study examined the contributions of maternal and peer support to depressive symptoms in early to mid-adolescence and variation in these contributions across age, gender, and race. Five waves of data on maternal support, peer support, and depressive symptoms were collected on rural youth (N = 3,444) at 6 month intervals. Multilevel modeling was used to evaluate within and between-person effects of maternal and peer support on depressive symptoms. Within-person effects of peer support did not vary by age, gender, or race. At the between-person level, peer support predicted levels of depressive symptoms at age 12, but this effect became nonsignificant after controlling for maternal support. Within-person effects of maternal support did not vary with age but were qualified by gender and race. Between-person effects of maternal support on depressive symptom levels at age 12 and slopes varied across race and gender, respectively. Findings highlight the robustness of the protective effects of maternal and peer support during adolescence among girls and white youth.

Gender Differences in Depressive Symptoms During Adolescence: The Contributions of Weight-Related Concerns and Behaviors.

A theoretical model of gender differences in depressive symptoms during adolescence was evaluated using data from Waves I and II of the National Longitudinal Study of Adolescent Health. The theoretical model under examination was primarily informed by the gender-additive model of gender differences in depressive symptoms during adolescence proposed by Stice and Bearman (2001). In the model, it was posited that BMI would be associated with perceiving oneself as overweight, which would then lead to a higher probability of dieting, which would be associated with greater depressive symptoms. Participants were 10,864 male and female adolescents. Gender did not moderate any of the model pathways, but mediation analysis indicated that gender differences in changes in depressive symptoms were mediated by perceived weight status and dieting. Findings suggest that one explanation for girls' higher depressive symptoms in adolescence relative to boys is girls' greater tendencies to perceive themselves as overweight and to diet.

Racial/ethnic differences in Body Mass Index: the roles of beliefs about thinness and dietary restriction.

The greater BMI of African American relative to Caucasian women is implicated in racial/ethnic disparities in health outcomes. The principal aim of the current study was to evaluate a theoretical account of racial/ethnic differences in BMI. Thin-ideal internalization, the perceived romantic appeal of thinness, dietary restriction, weight, and height were assessed via self-report measures on a sample of female undergraduates of African American (n=140) and Caucasian (n=676) race/ethnicity. Using structural equation modeling, support was obtained for the primary hypothesis that racial/ethnic differences in BMI are explained by Caucasian women's greater thin-ideal internalization and perceived romantic appeal of thinness, thereby resulting in greater levels of dietary restriction. Current findings illustrate the potential for racial/ethnic differences in sociocultural standards of appearance to influence racial/ethnic disparities in physical health, of which BMI is a marker, via effects on weight control behavior.

Adherence, body mass index, and depression in adults with type 2 diabetes: the mediational role of diabetes symptoms and self-efficacy.

OBJECTIVE: Evidence indicates that depression is linked to the development and worsening of diabetes, but the mechanisms underlying this link are not well understood. The authors examined the hypothesis that diabetes-related symptoms mediate the effect of both behavioral adherence and body mass index (BMI) on depression. In addition, they examined whether a prior finding that self-efficacy mediates the effect of behavioral adherence and BMI on depression would replicate with a larger sample size (W. P. Sacco, K. J. Wells, C. A. Vaughan, A. Friedman, S. Perez, & R. Morales, 2005). Also, the relative contributions of diabetes-related symptoms and self-efficacy to depression were evaluated. DESIGN AND PARTICIPANTS: Cross-sectional design involving adults diagnosed with Type 2 diabetes (N = 99). MAIN OUTCOME MEASURES: The primary outcome measure was depression (Patient Health Questionnaire: Nine Symptom Depression Checklist). Predictors of depression were diet and exercise adherence (Summary of Diabetes Self-Care Activities Questionnaire), diet and exercise self-efficacy (Multidimensional Diabetes Questionnaire), diabetes symptoms (Diabetes Symptom Checklist), and BMI (based on height and weight data from medical records). RESULTS: Path and mediation analyses indicated that adherence and BMI each contributed to depression indirectly, via their effects on self-efficacy and diabetes-related medical symptoms. CONCLUSION: Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms.

Depression in adults with type 2 diabetes: the role of adherence, body mass index, and self-efficacy.

Considerable evidence links depression with the development and worsening of diabetes, but the factors contributing to this link have not been established. The authors examined the role of adherence, body mass index (BMI), and self-efficacy. Adult patients with Type 2 diabetes (N = 56) completed self-report measures of diet and exercise adherence, diet and exercise self-efficacy, and depression. BMI was obtained from medical records. Path and mediation analyses indicated that both adherence and BMI independently contributed to self-efficacy. Self-efficacy mediated both the association between adherence and depression and the association between BMI and depression. These findings are consistent with the proposal that lower self-efficacy in reaction to adherence failure and higher BMI contributes to depression in adults with diabetes.
