In gerontology the most recognized and elaborate discourse about sampling is generally thought to be in quantitative research associated with survey research and medical research. But sampling has long been a central concern in the social and humanistic inquiry, albeit in a different guise suited to the different goals. There is a need for more explicit discussion of qualitative sampling issues. This article will outline the guiding principles and rationales, features, and practices of sampling in qualitative research. It then describes common questions about sampling in qualitative research. In conclusion it proposes the concept of qualitative clarity as a set of principles (analogous to statistical power) to guide assessments of qualitative sampling in a particular study or proposal.Questions of what is an appropriate research sample are common across the many disciplines of gerontology, albeit in different guises. The basic questions concern what to observe and how many observations or cases are needed to assure that the findings will contribute useful information. Throughout the history of gerontology, the most recognized and elaborate discourse about sampling has been associated with quantitative research, including survey and medical research. But concerns about sampling have long been central to social and humanistic inquiry (e.g., Mead 1953). The authors argue such concerns remained less recognized by quantitative researchers because of differing focus, concepts, and language. Recently, an explicit discussion about concepts and procedures for qualitative sampling issues has emerged. Despite the growing numbers of textbooks on qualitative research, most offer only a brief discussion of sampling issues, and far less is presented in a critical fashion (Gubrium and Sankar 1994;Werner and Schoepfle 1987;Spradley 1979Spradley , 1980Strauss and Corbin 1990;Trotter 1991; but cf. Denzin and Lincoln 1994;DePoy and Gitlin 1993;Miles and Huberman 1994;Pelto and Pelto 1978).The goal of this article is to extend and further refine the explicit discussion of sampling issues and techniques for qualitative research in gerontology. Throughout the article, the discussion draws on a variety of examples in aging, disability, ethnicity as well as more general anthropology.The significance of the need to understand qualitative sampling and its uses is increasing for several reasons. First, emerging from the normal march of scientific developments that builds on prior research, there is a growing consensus about the necessity of complementing standardized data with insights about the contexts and insiders' perspectives on aging and the elderly. These data are best provided by qualitative approaches. In gerontology, the historical focus on aging pathology obscured our view of the role of culture and personal meanings in shaping how individuals at every level of cognitive and physical functioning personally experience and shape their lives. The individual embodying a "case" or "symptoms" continues to make sense of, manage...

Assistive devices minimize limitations from physical impairment and are integral to rehabilitation. Little is known about older patients' concerns, perceptions, and beliefs about assistive devices. This study used a structured, qualitative approach to describe device perceptions of 103 stroke patients in rehabilitation. Six dimensions of patient concerns were identified, including the operation and utility of devices, social contexts and consequences, and attributions of cultural meanings of use. Initial device use posed cultural value dilemmas originating in discrepancies between sociocultural beliefs and conflicting normative expectations. Knowledge of these dimensions suggests new areas for social science research and refinements to clinical practice.

Aim To explore catalysts to, and circumstances surrounding, patient-to-worker violent incidents recorded by employees in a hospital system database. Background Violence by patients towards healthcare workers (Type II workplace violence) is a significant occupational hazard in hospitals worldwide. Studies to date have failed to investigate its root causes due to a lack of empirical research based on documented episodes of patient violence. Design Qualitative content analysis. Methods Content analysis was conducted on the total sample of 214 Type II incidents documented in 2011 by employees of an American hospital system with a centralized reporting system. Findings The majority of incidents were reported by nurses (39·8%), security staff (15·9%) and nurse assistants (14·4%). Three distinct themes were identified from the analysis: Patient Behaviour, Patient Care and Situational Events. Specific causes of violence related to Patient Behaviour were cognitive impairment and demanding to leave. Catalysts related to patient care were the use of needles, patient pain/discomfort and physical transfers of patients. Situational factors included the use/presence of restraints; transitions in the care process; intervening to protect patients and/or staff; and redirecting patients. Conclusions Identifying catalysts and situations involved in patient violence in hospitals informs administrators about potential targets for intervention. Hospital staff can be trained to recognize these specific risk factors for patient violence and can be educated in how to best mitigate or prevent the most common forms of violent behaviour. A social–ecological model can be adapted to the hospital setting as a framework for prevention of patient violence towards staff.

While the findings support a growing consensus that participation in leisure activities might significantly contribute to prevention of dementia, it also identifies major hindrances to progress. Important limitations detected include a lack of theoretical underpinnings, and little consensus and standardisation in the measured key variables. The study reinforces the critical need to overcome these limitations to enable health care professionals (e.g. occupational therapists) to make evidence-based recommendations for increased participation in activities as a means of promoting health and preventing cognitive decline.

Alcohol consumption has been associated with HIV disease progression; yet, the nature of this association is poorly understood. This study sought to determine the influence of patient beliefs about alcohol on ART adherence, and elucidate clinician beliefs about drinking and taking ART. Most patients (85%) believed alcohol and ART do not mix. The three alcohol consumption groups, light, moderate, and heavy, differed in their beliefs about drinking and ART with 64% of light and 55% of moderate drinkers skipping ART when drinking compared to 29% of heavy drinkers. Beliefs were derived from folk models of alcohol-ART interaction. Patients 50 and older were less likely to skip ART when drinking. Alcohol appears to affect adherence through decisions to forgo ART when drinking not through drunken forgetfulness. Furthermore, over onehalf of clinicians believed alcohol and ART should not be taken together. These findings have implications for patient care and physician training.

This study examined differences between self-report and actual documentation of workplace violence (WPV) incidents in a cohort of health care workers. The study was conducted in an American hospital system with a central electronic database for reporting WPV events. In 2013, employees (n = 2010) were surveyed by mail about their experience of WPV in the previous year. Survey responses were compared with actual events entered into the electronic system. Of questionnaire respondents who self-reported a violent event in the past year, 88% had not documented an incident in the electronic system. However, more than 45% had reported violence informally, for example, to their supervisors. The researchers found that if employees were injured or lost time from work, they were more likely to formally report a violent event. Understanding the magnitude of underreporting and characteristics of health care workers who are less likely to report may assist hospitals in determining where to focus violence education and prevention efforts.

Objective-The aim of this study was to discover and characterize components of engagement in creative activity as occupational therapy for elderly people dealing with life-threatening illness, from the perspective of both clients and therapists. Despite a long tradition of use in clinical interventions, key questions remain little addressed concerning how and why people seek these activities and the kinds of benefits that may result.Method-Qualitative interviews were conducted with 8 clients and 7 therapists participating in creative workshops using crafts at a nursing home in Sweden. Analysis of the interviews was conducted using a constant comparative method.Findings-Engaging in creative activity served as a medium that enabled creation of connections to wider culture and daily life that counters consequences of terminal illness, such as isolation. Creating connections to life was depicted as the core category, carried out in reference to three subcategories: (1) a generous receptive environment identified as the foundation for engaging in creative activity; (2) unfolding creations-an evolving process; (3) reaching beyond for possible meaning horizons. Conclusion-The findings suggest that the domain of creative activity can enable the creation of connections to daily life and enlarge the experience of self as an active person, in the face of uncertain life-threatening illness. Ultimately, the features that participants specify can be used to refine and substantiate the use of creative activities in intervention and general healthcare.

Strict adherence to medication regimens is generally required to obtain optimal response to combination antiretroviral therapy (ART). Yet, we have made limited progress in developing strategies to decrease the prevalence of nonadherence. As we work to understand adherence in developed countries, the introduction of ART in resource-poor settings raises novel challenges. Qualitative research is a scientific approach that uses methods such as observation, interviews, and verbal interactions to gather rich in-depth information about how something is experienced. It seeks to understand the beliefs, values, and processes underlying behavioral patterns. Qualitative methods provide powerful tools for understanding adherence. Culture-specific influences, medication beliefs, access, stigma, reasons for nonadherence, patterns of medication taking, and intervention fidelity and measurement development are areas ripe for qualitative inquiry. A disregard for the social and cultural context of adherence or the imposition of adherence models inconsistent with local values and practices is likely to produce irrelevant or ineffective interventions. Qualitative methods remain underused in adherence research. We review appropriate qualitative methods for and provide an overview of the qualitative research on ART nonadherence. We discuss the rationales for using qualitative methods, present 2 case examples illustrating their use, and discuss possible institutional barriers to their acceptance.
