1.  Social Support Theoretical Perspective

2.  Design and evaluation of theory-informed technology to augment a wellness motivation intervention 
Integrating mobile technology into health promotion strategies has the potential to support healthy behaviors. A new theory-informed app was designed to augment an intervention promoting wellness motivation in older adults with fall risk and low levels of physical activity. The app content was evaluated for clarity, homogeneity, and validity of motivational messages; both the app and device were evaluated for acceptability and usability. The initial evaluation included nine adults (mean age, 75); four of whom also assessed the app’s sensing abilities in the field. As part of an intervention feasibility study, 14 older adults (mean age, 84) also provided a follow-up evaluation of app usability. Evaluation participants assessed the app as valid, usable, acceptable, and able to sense most reported free-living activities, and provided feedback for improving the app. Design processes illustrate methodologic and interpretive efforts to operationalize motivational content in a theory-informed app promoting change in physical activity behavior.

3.  External Validity of Physical Activity Interventions for Community-Dwelling Older Adults with Fall Risk: A Quantitative Systematic Literature Review 
Journal of advanced nursing  2012;68(10):2140-2154.
To appraise the external validity of physical activity interventions designed to reduce falls among community-dwelling older adults, using the reach, efficacy/effectiveness, adoption, implementation, and maintenance framework.
Falls are a globally common, significant, and preventable problem. The efficacy of physical activity interventions to reduce falls among older adults is well established. Translation of this research into practice is slow as evidenced by persistently low proportions of older adults who engage in physical activities and the rising incidence of falls.
Data Sources
Four electronic databases were searched for relevant studies published between 2000 and 2010. Studies that examined the effects of physical activity interventions designed to reduce falls among community dwelling older adults were included in this review (n = 46).
Review Methods
This was a quantitative systematic review with narrative synthesis. The reach, efficacy/effectiveness, adoption, implementation, and maintenance framework guided the identification, appraisal, and synthesis of indicators representing study validity.
The majority of studies in this review described indicators representing internal validity. Details about indicators representing external validity were reported infrequently, limiting the generalizability of fall-preventive physical activity interventions in diverse cultures and social contexts over time.
To foster translational research in real world settings, additional programmatic intervention research is needed that: (a) targets diverse populations; (b) incorporates theories of behavioural change; (c) describes and operationalizes critical content that enables replication and translation; (d) tests innovative measures of fall risk and physical activity; and (e) evaluates feasibility and acceptability.

5.  ReadySteady: App for Accelerometer-based Activity Monitoring and Wellness-Motivation Feedback System for Older Adults 
Increased physical activity and exercise have been found to reduce falls and decrease mortality and age-related morbidity in older adults. However, a large percentage of this population fail to achieve the necessary levels of activity needed to support health living. In this work, we present a mobile app developed on the iOS platform that monitors activity levels using accelerometry. The data captured by the sensor is utilized to provide real-time motivational feedback to enable reinforcement of positive behaviors in older adults. Pilot experiments (conducted with younger adults) performed to assess validity of activity measurement showed that system accurately measures sedentary, light, moderate and vigorous activities in a controlled lab setting. Pilot tests (conducted with older adults) in the user setting showed that while the app is adept at capturing gross body activity (such as sitting, walking and jogging), additional sensors may be required to capture activities involving the extremities.

6.  Salud de Corazon: Cultural Resources for Cardiovascular Health among Older Hispanic Women 
The prevalence of cardiovascular disease risk factors in Hispanic women has been substantiated across studies. While many studies have focused on the impact of these risk factors, few qualitative studies have addressed cultural and contextual meanings of cardiovascular health promotion in this population. This research explored cultural resources for cardiovascular health promotion among older Hispanic women. A qualitative descriptive methodological design using focus groups with 7 Hispanic women was used. Culture provided an overarching perspective, guiding identification and choice of resources and supports in order to promote cardiovascular health. Themes included Living Tradition, Caring for Family, Connecting with Friends, Having Faith, and Moving as Life. Data provide an initial step toward generating a more complete understanding of perceived cultural resources for cardiovascular health in older Hispanic women. Researchers and clinicians are increasingly recognizing that individuals, families and communities uniquely define cultural and contextual meaning of cardiovascular health promotion.

7.  Review of Intervention Studies Promoting Physical Activity in Hispanic Women 
The objectives of this review were to: (a) provide a comprehensive review and evaluation of intervention studies designed to promote physical activity among Hispanic women; and (b) provide recommendations for future research involving Hispanic women in physical activity intervention research.
Computer and manual searches were conducted of articles in the English-language literature from 1980 to present.
Tweleve articles were evaluated, with emphasized physical activity intervention in Hispanic women. A review of current intervention research provides a starting point for determining salient approaches for intervention and evaluation, issues related to program implementation, and the strengths and limits of existing approaches.
Over the past 30 years, very few interventions have been conducted that examines foster physical activity among Hispanic women; those that include Hispanic women across ages support the need for interventions that build upon the strengths and address the limitations of this body of research.

8.  Validity and Reliability of the Index of Self-Regulation Scale for Physical Activity in Older Korean Americans 
Nursing Research and Practice  2011;2011:329534.
The Korean version of the index of self-regulation (KISR) is a nine-item scale designed to measure individuals' level of self-regulation for physical activity. The purpose of this study was to test the psychometric properties of the KISR, including reliability and validity, in a group of older Korean Americans. The KISR was administered to a sample of older Korean Americans at a baseline interview (Time 1) and 12 week followup (Time 2). The internal consistency of the KISR was high at both time points, with Cronbach's alphas of .94 and .95, respectively. The test-retest reliability was moderate-to-high at .68. There was evidence of construct validity of the KISR based on its moderate to high significant correlations with theoretically relevant variables, including motivational appraisal and self-efficacy for physical activity. A principal axis factoring with an oblique rotation resulted in two factors, explaining 89% of the variance. The KISR is a reliable and valid measure to assess the level of self-regulation for physical activity behavior in older Korean Americans.

Recruiting older adults to participate in intervention research is essential for advancing the science in this field. Developing a relevant recruitment plan responsive to the unique needs of the population before beginning a project is critical to the success of a research study. This paper describes our experiences in the process of recruitment of homebound older adults to test a community-based health empowerment intervention. In our study, the trust and partnership that existed between the research team and Community Action Agency facilitated the role of the home-delivered meal drivers as a trusted and untapped resource for study recruitment. Researchers can benefit from thinking creatively and developing meaningful partnerships when conducting research with older adults.
