  • Considering depression as a risk factor for early disengagement in a 12-month eHealth weight loss intervention

    Open AccessLisa Hurley, Lex Hurley et al.ARTICLEJournal of Health Psychology2025Referências: 39

    Depression is often described as likely associated with engagement and risk of disengagement (i.e. non-usage attrition) in digital behavior change interventions, but is rarely studied in-depth outside of mental health-specific programs; thus, we sought to quantify its influence on disengagement risk. Data come from 363 adults (mean age = 51.86, SD = 10.86; 70.3% female) randomized to the intervention groups of the LoseNowPA eHealth weight managem…

  • Supporting physical activity adoption through recommender system technology

    Open AccessJennifer P Agans, Fenglong Ma et al.ARTICLEJournal of Health Psychology2025Referências: 38

    We tested the potential for recommender system technology to provide personalized physical activity (PA) suggestions for inactive young adults with high bodyweight. We developed a recommender system using data from the 2017 Behavioral Risk Factor Surveillance System and assessed interest in using the system among 47 young adults (mean age = 23.0 years; 63.4% female; 65.0% White; mean BMI = 29.4). Eleven of these participants (mean age = 23.6 year…

  • Motivation, accountability, and outcomes in a randomized controlled trial of internet weight-loss programs in primary care

    Open AccessCaitlin E Martinez, Brooke T Nezami et al.ARTICLEJournal of Health Psychology2025Referências: 29

    This study explored whether baseline autonomous motivation (AM), controlled motivation (CM), and relative autonomy index (RAI) scores predicted 12-month weight in a three-arm randomized controlled trial of internet weight loss programs in primary care. It also evaluated perceived accountability to a primary care provider for weight loss as a moderator and study engagement (operationalized as weeks logged into the study website) as a mediator of t…

  • Broad versus narrow bandwidth measures of experienced automaticity for physical activity

    Jenny L Olson, Scherezade K Mama et al.ARTICLEPsychology & Health2024

    Objective: Physical activity is important for health, yet most young adults are insufficiently active. Physical activity is regulated in part, by habit, typically operationalised as automaticity. Little is known about the characteristics of automaticity, or whether broad bandwidth unidimensional measures of automaticity for physical activity are superior to narrower bandwidth multi- dimensional measures. Design: This secondary analysis (N = 238) …

  • The Association between Gender and Physical Activity Was Partially Mediated by Social Network Size during Covid-19

    Open AccessAshley Kuzmik, Yin Liu et al.ARTICLEInternational Journal of…2022

    The COVID-19 pandemic has disrupted physical activity, particularly among women. Limited research has explored how social network support may explain gender-based variations in physical activity during COVID-19. The purpose of this study was to examine the mediating role of social networks in the association between gender and physical activity during a pandemic. This cross-sectional survey assessed whether social network characteristics (i.e., i…

  • Reproductive Life Planning and Contraceptive Action Planning for Privately Insured Women

    Open AccessCynthia H Chuang, Carol S Weisman et al.ARTICLEPerspectives on Sexual and…2019

    The study does not provide evidence that web-based RLP influences contraceptive behaviors in insured women outside of the clinical setting. Further research is needed to identify strategies to help women of reproductive age identify contraceptive methods that meet their needs and preferences

  • Reducing Unintended Pregnancies Through Web-Based Reproductive Life Planning and Contraceptive Action Planning among Privately Insured Women

  • Structural social support predicts functional social support in an online weight loss programme

    Open AccessKevin O Hwang, Jason M Etchegaray et al.ARTICLEHealth Expectations2014

    Background Online weight loss programmes allow members to use social media tools to give and receive social support for weight loss. However, little is known about the relationship between the use of social media tools and the perception of specific types of support. Objective To test the hypothesis that the frequency of using social media tools (structural support) is directly related to perceptions of Encouragement, Information and Shared Exper…

  • "Weighing" Two Qualitative Methods

    Open AccessHeather L Stuckey, Jennifer L Kraschnewski et al.ARTICLECAM2014Citada por: 2Referências: 36

    Two primary forms of qualitative data collection in the health and social sciences include self-report interviews and direct observations. This study compared these two methods in the context of weight management for people who had varying degrees of success with weight loss ( n = 20). We asked general habits of eating as well as barriers to weight loss and maintaining a healthy diet. Video-recorded observations (20 minutes) followed audio-record…

  • A Silent Response to the Obesity Epidemic

    Jennifer L Kraschnewski, Christopher Sciamanna et al.ARTICLEMedical Care2013Referências: 26

    BACKGROUND: Guidelines recommend that physicians screen all adults for obesity and offer an intensive counseling and behavioral interventions for weight loss for obese adults. Current trends of weight-related counseling are unknown in the setting of the US obesity epidemic. OBJECTIVES: To describe primary care physician (PCP) weight-related counseling, comparing counseling rates in 1995-1996 and 2007-2008. RESEARCH DESIGN: Data analysis of outpat…

  • Using Positive Deviance for Determining Successful Weight-Control Practices

    Open AccessHeather L Stuckey, Jarol Boan et al.ARTICLEQualitative Health Research2011Citada por: 10Referências: 49

    Based on positive deviance (examining the practices of successful individuals), we identified five primary themes from 36 strategies that help to maintain long-term weight loss (weight control) in 61 people. We conducted in-depth interviews to determine what successful individuals did and/or thought about regularly to control their weight. The themes included weight-control practices related to (a) nutrition: increase water, fruit, and vegetable …

  • Ethnic/Racial Disparities in Hospital Procedure Volume for Lung Resection for Lung Cancer

    Charles J Neighbors, Meghan L Rogers et al.ARTICLEMedical Care2007Referências: 48

    BACKGROUND: Ethnic/racial minorities experience poorer outcomes from lung cancer than non-Hispanic whites. Higher hospital procedure volume is associated with better survival from lung resection for lung cancer. OBJECTIVES: We examined whether (1) ethnic/racial minorities are more likely to obtain lung resections at lower volume hospitals, (2) ethnicity/race is associated with inpatient mortality, (3) hospital volume mediates this association, an…

  • Cardiovascular comorbidities among public health clinic patients with diabetes

    Open AccessJessica M Robbins, David Webb et al.ARTICLEBMC Public Health2005

    Cardiovascular comorbidities were common both before and after diabetes diagnosis in this low-income cohort, but not substantially different from mixed-income managed care populations, perhaps as a consequence of access to primary care and pharmacy services

  • Effects of a Fingerprint Reader on Survey Responses of Primary Care Patients

    Open AccessChristopher Sciamanna, Christopher N Sciamanna et al.ARTICLEJournal of Health Psychology2003Referências: 9

    Given the potential of patients using computer programs in health care settings, we studied the effect of a fingerprint reader on responses to a computerized health screener. We randomized 76 primary care patients into two conditions: (1) fingerprint reader prior to screener; and (2) control condition. Overall, the reader was well accepted and those who used it had more positive attitudes toward using it than those who did not. The fingerprint re…

  • Dissemination of the AHCPR clinical practice guideline in community health centres

    Judith D DePue, Michael G Goldstein et al.ARTICLETobacco Control2002

    This guideline dissemination effort resulted in quite different provider counselling rates across patient sexes, and visit types. Guideline implementation may require more sustained efforts, with multiple strategies, which are reinforced at higher policy levels, to more fully integrate tobacco interventions into routine primary care practice with all patients who smoke
