The Brief Lexington Attachment to Pets Scale
Pet attachment is a phenomenon widely studied in various cultures, but little attention has been devoted to whether it varies across cultures. This topic requires a valid invariant instrument to measure pet attachment. Thus, the aim of this study was cross-cultural examination of the Lexington Attachment to Pets Scale (LAPS). A total of 906 respondents from India, Italy, Poland, and Russia took part in the study. The initial version of LAPS has 2…
Sources of HIV information and women’s HIV knowledge in Southwest Sumba Indonesia
The study's results suggest that more extensive in-depth HIV education is greatly needed to help prevent transmission among women living in small and outlying islands in Indonesia. Wider promotion of HIV information through the media and more intensively through local healthcare providers appears a promising and likely effective means to reach these women
Laps Sa
Human biological and cultural evolution is tied to the relationships established with other animals. Attachment is one of the mechanisms established between dogs/cats and humans and allows the generation of affective bonds and close proximity. Many instruments have been used to study attachment of people to their dogs/cats, such as the Lexington Attachment to Pets Scale (LAPS). Our aim was adapting LAPS for South American populations (Brazil, Arg…
Economic stressors, alcohol use, and health-related quality of life in middle-aged adults
1359 adults ages 40-61 (65.0% women). High economic stress was associated with poor physical and mental HRQoL, and high community disadvantage was linked to poor physical HRQoL only. High alcohol use predicted high physical and mental HRQoL, and low misuse predicted high mental HRQoL only. There was no evidence of mediation, and gender, age, and race moderated a subset of model paths. The discussion considers future directions for research and im…
Profiles of economic and non-economic chronic stressors at midlife
1541 adults ages 40-61 years (35.5 % male, 48.7 % white) responded to questionnaires. Latent profile analyses revealed five stressor profiles, specifically Low Stressors (46.3 % of the sample), Mixed Stressors (22.7 %), High Sicktime Stressors (14.7 %), High Unemployment Stressors (8.5 %), and High Stressors (7.9 %). Respectively, the Low and High Stressor profiles were the most and least advantaged in terms of demographic risk factors, social su…
Service capacity and disability resource integration
Immigrants and refugees in the United States often face significant barriers in accessing social services, including mental health support, legal assistance, ESL or related education, housing, vocational training, workforce resources, transportation, and citizenship support. This article explores the strengths and challenges of community‐based organizations welcoming centers (CBO WC) in Illinois that serve these populations, including people with…

Public perceptions of pollsters in the United States
Objective: Anecdotal evidence suggests that the term “pollster” has, in recent years, become stigmatized in the United States. We explore this and a subsequent question as to whether negative perceptions of pollsters affect people's perceived trustworthiness of survey findings. Methods: Survey experiments were administered to national probability‐based samples after the 2016 and 2020 elections. Results: In each study, pollsters obtained significa…

Effects of chronic workplace harassment on mental health and alcohol misuse
Background Research on the impacts of exposure to workplace harassment (WH) is largely cross-sectional, and existing prospective studies generally are between two and five years of follow-up, with the longest US study being 10 years. However, the effects of exposure to WH may persist longer, particularly if exposure has been chronic. This study fills this gap by examining effects of prior exposure to chronic sexual and generalized WH on psycholog…

Survey participation as a function of democratic engagement, trust in institutions, and perceptions of surveys
Objective With response rates of large‐scale surveys having decreased significantly over the years and rebounds seeming unlikely, many studies now examine how response rates vary with methodological design and incentives. This investigation delves into how individual‐level factors shape survey participation. Specifically, we examine the influence of individuals’ democratic engagement and their trust in institutions on intent to participate in sur…
Individual-Level Cultural Factors and Use of Survey Response Styles Among Latino Survey Respondents
Acquiescent (ARS) and extreme response styles (ERS) can have detrimental effects on survey data and, for unknown reasons, are more frequently used by Latino than non-Latino white respondents. This exploratory study examined the influence of culture on these response styles by investigating their associations with individual-level cultural factors and ARS and ERS among 1,296 Mexican American, Puerto Rican, and Cuban American telephone survey respo…
Covid-19 and the academy
Much of the available evidence regarding COVID-19 effects on the scientific community in the U.S. is anecdotal and non-representative. We report findings from a based survey of university-based biologists, biochemists, and civil and environmental engineers regarding negative and positive COVID-19 impacts, respondent contributions to addressing the pandemic, and their opinions regarding COVID-19 research policies. The most common negative impact w…

Comparing Postpartum Care Utilization from Medicaid Claims and the Pregnancy Risk Assessment Monitoring System in Wisconsin, 2011–2015
The influence of financial practice in developing mathematical probability
The purpose of this paper is to discuss the role of financial practice in the development of mathematics as applied in human judgement. The basis of the paper is in historical research from the 1990s that argues that the monetisation of western commerce, which abstracted value into quantified price, was synthesised with scholastic analysis resulting in a “mathematical mechanistic world picture” that led to the widespread use of mathematics in sci…

A Community-Driven Probability Survey of Disadvantaged Populations in Chicago
Hyper-local data are especially critical for diverse and segregated cities such as Chicago. Lessons learned can be applied to future community surveys done by hospital systems, health departments, and community advocates to maximize the usefulness of findings
The Influence of Item Characteristics on Acquiescence among Latino Survey Respondents
Acquiescence is often defined as the systematic selection of agreeable ("strongly agree") or affirmative ("yes") responses to survey items, regardless of item content or directionality. This definition implies that acquiescence is immune to item characteristics; however, the influence of item characteristics on acquiescence remains largely unexplored. We examined the influence of eight item characteristics on acquiescence in a telephone survey of…
Measuring the Elusive Construct of Personalismo Among Mexican American, Puerto Rican, and Cuban American Adults
Personalismo may have a broad influence on the well-being of U.S. Latinos by shaping social networks and, in turn, access to information and resources. However, research on personalismo is currently constrained by the lack of a psychometrically sound measure of this cultural construct. This research used a mixed-methods approach to develop a personalismo scale across three studies: a cognitive interviewing study with Mexican American adults ( n =…
Why Do Latino Survey Respondents Acquiesce? Respondent and Interviewer Characteristics as Determinants of Cultural Patterns of Acquiescence Among Latino Survey Respondents
Research indicates that Latino survey respondents are more likely to acquiesce than non-Latino European Americans (EAs), thereby decreasing the potential for measurement invariance across cultural groups. To better understand what drives this culturally patterned response style, we examined the influence of respondent and interviewer characteristics on acquiescence. Data were obtained from a telephone survey of 400 Mexican American, Puerto Rican,…
Effects of Rosa’s Law on Intellectual-Disability Reporting
This study examines the effects of legislatively mandated changes in terminology for National Health Interview Survey (NHIS) questions on proxy and self-reports of an important condition. Specifically, we examine changes from the use of the term “mental retardation” to “intellectual disability” that were mandated by what is now known as “Rosa’s Law,” an act signed by President Obama in October 2010. Our analyses focus on changes in national preva…

Validation of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being-expanded (Facit-Sp-Ex) across English and Spanish-speaking Hispanics/Latinos
The validity of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) has been examined in primarily non-Hispanics/Latinos with chronic illness. This study assessed the psychometric properties of the non-illness, expanded FACIT-Sp (FACIT-Sp-Ex) in 5,163 U.S. Hispanic/Latino adults. Measures were interviewer-administered in English or Spanish. Confirmatory factor analyses indicated four factors: Meaning, Peace, Faith…
Psychometric Evaluation of the Lexington Attachment to Pets Scale (Laps)
This paper reports on the development and psychometric evaluation of a scale for assessing emotional attachment of individuals to their pets. Previous attachment scales have suffered variously from low internal consistency and reliance on small or nonrepresentative samples for their development. Telephone interviews of a random, representative sample of 412 pet owners in Fayette County, Kentucky, were completed in September 1990; a 69.5 percent r…
Pet Ownership and Attachment as Supportive Factors in the Health of the Elderly
In order to examine pet ownership and pet attachment as factors supporting the health of the elderly, a national probability sample of Americans 65 years of age and older was drawn. Participants answered telephone survey questions regarding pet ownership, life stress, social support, depression, and recent illness. In multiple regression analyses, pet ownership failed to predict depression and illness behavior, while pet attachment significantly …
Measuring Everyday Racial/Ethnic Discrimination in Health Surveys
While it is clear that self-reported racial/ethnic discrimination is related to illness, there are challenges in measuring self-reported discrimination or unfair treatment. In the present study, we evaluate the psychometric properties of a self-reported instrument across racial/ethnic groups in a population-based sample, and we test and interpret findings from applying two different widely-used approaches to asking about discrimination and unfair…
The Relation Between Culture and Response Styles
The authors investigated at the country level the effects of four cultural orientations identified and studied by Hofstede on two commonly recognized response biases: extreme response style and acquiescent responding. Data are presented from approximately 18,000 survey questionnaires completed by employees in 19 nations on five continents (Australia, Belgium, Brazil, Czech Republic, Germany, Hungary, India, Japan, Malaysia, Portugal, Turkey, the …
Survey Research in Public Administration
Survey research is a common tool for assessing public opinions, perceptions, attitudes, and behaviors for analyses in many social science disciplines. Yet there is little knowledge regarding how specific elements of survey research methodology are applied in practice in public administration. This article examines five mainstream public administration journals over an eight‐year period regarding current methodological practice, organized around t…
The Impact of Question and Respondent Characteristics on Comprehension and Mapping Difficulties
Behavior coding is one technique researchers use to detect problems in survey questions, but it has been primarily explored as a practical tool rather than a source of insight into the theoretical understanding of the cognitive processes by which respondents answer survey questions. The latter is the focus of the current investigation. Using data from a large study in which face-to-face interviews were taped and extensive behavior coding was done…
What is the relation between cultural orientation and socially desirable responding
Research suggests that collectivists are more likely to engage in deception and socially desirable responding to maintain good relationships with others. In contrast, individualists are portrayed as candid and sincere because individualism encourages people to "be yourself." The authors propose that people with both types of cultural orientations or backgrounds engage in desirable responding, albeit in distinct ways. In Study 1, respondents from …
Pet Ownership and Attachment in Relation to the Health of U.S. Adults, 21 to 64 Years of Age
Pet ownership and attachment to a pet have been reported to have a salutary influence on health in selected populations. General population surveys of the beneficial effects of pet ownership have not been conducted. The purpose of this national survey was to examine the relationship of pet ownership and attachment to self-reported illness behavior and emotional distress in three stages of life: early adulthood (21 to 34 years of age), early middl…

Sexual harassment and generalized workplace abuse among university employees
OBJECTIVES: This study hypothesized that interpersonal workplace stressors involving sexual harassment and generalized workplace abuse are highly prevalent and significantly linked with mental health outcomes including symptomatic distress, the use and abuse of alcohol, and other drug use. METHODS: Employees in 4 university occupational groups (faculty, student, clerical, and service workers; n = 2492) were surveyed by means of a mailed self-repo…
Quality of Attachment to Companion Animals among U.S. Adults 21 to 64 Years of Age
Previous reports of scales and indices used in studying attachment to companion animals have not included representative samples of the United States population or have failed to show good psychometric properties. This report includes psychometric analyses of a companionanimal attachment scale used among a national probability sample of United States adults aged 21 to 64 years. Internal structures of the scale were shown to be good with all eight…
Mental Health, Social Relations, and Social Selection
A wide body of literature documents the effect of social networks and social supports on mental health. Fewer studies, however, have examined the reciprocal effect of mental health on social relationships. This problem is examined using data from a national panel survey of adults aged 20-64. For the sample as a whole, support was found for a social selection process, since psychological distress predicted decreases in primary, but not secondary, …
Racial Disparities in Political Participation Across Issues
Attachment to Companion Animals among Older Pet Owners
Psychometric properties are examined in a pet-attachment index used in a national probability survey of households including at least one resident aged 65 or older. Cronbach's alpha for the overall scale was 0.58, indicating low but acceptable internal reliability. Internal structure was evaluated using principal-components analysis. Two factors were identified. Responses to individual questions in the index were associated with a number of respo…
Coming out in color
Disclosing one's sexual minority identity, or "coming out," has varying effects on the mental health of lesbians. Previous research indicates a negative association between disclosure and depression. However, these findings are based on research with White lesbians. To date, there is a paucity of studies that examined how the relationship between disclosure and depression may differ by race/ethnicity among lesbians. To address this gap, we examin…
Survey Mode Effects on Data Quality
Web surveys are being increasingly incorporated into national survey data collection programs in the United States because of their cost/time-efficiencies. Yet, response rates and data quality issues in web surveys remain important challenges. As a basic study designed to better understand data quality in a mixed mode national survey, this article investigates the degree to which web versus mail survey modes affect unit and item responses. Findin…
Demographics of Pet Ownership among U.S. Adults 21 to 64 Years of Age
A telephone survey of a national probability sample of U.S. adults 21 to 64 years old contrasts the demographic characteristics of 816 pet owners and 448 non-owners residing in 1,300 households from 47 states and the District of Columbia.Significant differences between owners and non-owners were found to relate to age groups, number of people and number of children in the household, race, marital status, income, rural/urban residence, and occupat…
Culture Moderates the Relation Between Perceived Stress, Social Support, and Mental and Physical Health
Cultural differences in the relations between perceived stress and mental and physical health, and the role of social support in buffering these relations, are examined in a survey of multiple U.S. cultural/ethnic groups. Findings from a health survey of N = 603 adults comprising approximately equal numbers of non-Hispanic Whites, Mexican Americans, Korean Americans, and African Americans show that perceived stress is negatively correlated with o…
Using Community-Level Correlates to Evaluate Nonresponse Effects in a Telephone Survey
Understanding the relationship between nonresponse processes and key research variables is central to evaluating if and how nonresponse introduces bias into survey estimates. In most telephone surveys, however, little information is available with which to estimate these effects. We report a procedure for examining the potential effects of nonresponse via analyses that (1) investigate the linkages between community-level (zip code) variables and …
Prediction of Depressive Distress in a Community Sample of Women
Objectives. This study compared factors known or hypothesized to influence depressive symptomatology in a community sample of lesbians and heterosexual women. Methods. Data were collected in a multisite survey of lesbians' physical and mental health. Results. Findings confirmed earlier reports suggesting that traumatic life events such as physical and sexual abuse, and individual traits and coping styles are risk factors for depressive distress. …
Response Heaping in Interviewer-Administered Surveys
Response heaping (also referred to as rounding or digit preference) occurs when respondents show a preference for rounded numbers (often those divisible by five or 10). Conventional wisdom is that this is the result of taking cognitive shortcuts to make question answering easier, and as such, that it may be a form of survey satisficing. In four studies, we test this conventional wisdom for the first time by exploring whether response heaping occu…

Longitudinal Associations among Discordant Sexual Orientation Dimensions and Hazardous Drinking in a Cohort of Sexual Minority Women
We examined differences between sexual minority women's (SMW's) sexual identity and sexual behavior or sexual attraction as potential contributors to hazardous drinking across a 10-year period. Data are from a longitudinal study examining drinking and drinking-related problems in a diverse, community-based sample of self-identified SMW (Wave 1: n = 447; Wave 2: n = 384; Wave 3: n = 354). Longitudinal cross-lagged models showed that SMW who report…
Delaying Justice
Some of the Supreme Court’s most famous cases—from Roe v. Wade (1973) to Brown v. Board of Education (1954)—have been decided only after being held over and argued a second time. While few cases take this path, scholars have offered no systematic account for why the Court would ever take such a tack. We develop hypotheses about when reargument is most likely to occur, and test them on all formally decided cases between 1946 and 1985. More specifi…
Physician shortage in Kentucky, 1930-1980
Changes in the number and locations of Kentucky counties with a shortage of physicians (using current federal definitions of medical underservice) were examined for the decennial years 1930 to 1980. The number of counties with a physician shortage were found to have increased from four per cent in 1930 to 20 per cent in 1970 and 1980. The per cent of population in physician shortage counties was also found to have increased between 1930 and 1970,…
The Influence of Rural Physicians' Perceptions on Referral Patterns to a University Hospital
The patient referral process is based on a complex set of social rewards and costs for the referring physician. For the physician or institution potentially receiving referrals, a key question is, why is one institution selected over other available choices? Factor analysis of a survey of rural physicians revealed five factors of reward and cost associated with the choice of where to refer patients. Further analysis of these factors suggested tha…
Evaluation of Medical Center Support for Rural Physicians
Professional isolation remains a problem for rural physicians. To address the problem, a university medical center established a Physician Support Office (PSO). The PSO offered rural physicians toll‐free telephone access to patient referral, patient follow‐up, library reference, and drug information services. A newsletter was also published. The service was evaluated using a quasi‐experimental design. Physicians in the experimental area felt ther…

Social Networks and Depression Among the Elderly
Contradictory findings have been reported about depression in the elderly living in metropolitan and nonmetropolitan regions of the United States. Additionally, the extent to which the same sets of variables are predictive of depression among the elderly living in metropolitan and nonmetropolitan environments is unknown. We examined these issues using the Center for Epidemiologic Studies Depression Scale (CES‐D) and a national sample of elderly r…

A Fairly Common Ambiguity
Although public assessments of the performance of elected officials are often measured by job rating questions using easily understood language, answers to such questions can be difficult to interpret because of their use of generic words containing multiple meanings. The word “fair,” which is often presented as a response intended to signify mild disapproval, is particularly problematic in this regard. Because of this problem, we have used a sta…

Dimensions of Mail Questionnaires and Response Quality
Les AA. estiment que les questionnaires de petite dimension sont des instruments d'enquete moins efficaces que les formulaires standards. Lire et completer un petit document n'offre pas l'avantage de paraitre, aux yeux des enquetes, comme une tâche plus modeste. En revanche l'utilisation de grands formulaires peut donner l'impression de participer a une recherche importante. Ceci peut inciter les individus a repondre aux questions des enqueteurs.…
The Computer Presentation of Musical Research
The traditional format for the presentation of musical research, the journal article, makes referencing musical passages less direct than ideally desired. CD-ROM technology provides a means for the presentation of written comments and analytical sketches simultaneously with a recorded performance of the corresponding music. This article describes a computer project that uses CD-ROM technology to bridge the gap between analytical or theoretical co…

Examining the Effectiveness of a Community‐Based Self‐Help Program to Increase Women's Readiness for Smoking Cessation
This study investigated the effectiveness of two components of a smoking cessation intervention: a reading manual and a series of televised programs. Female smokers in the Chicago metropolitan area with a high school education or less were interviewed at 4 different times: baseline, immediate postintervention, and 6 and 12 months. We examined the effects of several baseline measures (race, age, number of cigarettes smoked, and stage of readiness …
Changes in Self-Efficacy and Readiness for Smoking Cessation among Women with High School or Less Education
The most common theory of smoking cessation postulates that readiness to quit begins with changes in attitudes that move the smoker toward behavioral change and eventual cessation. However, trends in smoking indicate that many who currently smoke are not ready to quit. Hence, strategies that both enhance readiness and focus on quitting are likely to be most effective. We hypothesize that an intervention addressed to motivating behavior change wil…
Prediction of Depressive Distress in a Community Sample of Women
Objectives. This study compared factors known or hypothesized to influence depressive symptomatology in a community sample of lesbians and heterosexual women. Methods. Data were collected in a multisite survey of lesbians' physical and mental health. Results. Findings confirmed earlier reports suggesting that traumatic life events such as physical and sexual abuse, and individual traits and coping styles are risk factors for depressive distress. …
Cross-Cultural Interviewing
Improving the self reporting of tobacco use
The tobacco specific survey introduction is causing some smokers to deny their tobacco use. The data suggest that these smokers tend to be women that smoked occasionally. A desire by the participants to minimise their personal time costs or a growing social disapproval of tobacco use in the USA may be contributing to the creation of previously undetected survey artefacts in the measurement of tobacco related behaviours
