TL;DR: The National Council on Pet Population Study and Policy (NCPPSP) as mentioned in this paper found that behavioral problems, including aggression toward people or nonhuman animals, were the most frequently given reasons for canine relinquishment and the second most frequent reason for feline relinquishment, and no association was found between category of relinquishment (behavioral, mixed, nonbehavioral) and gender, number of times mated (males), number of litters (females), purebred status, declaw status, and number of visits to the veterinarian within the past year, for
Abstract: The Regional Shelter Relinquishment Study sponsored by the National Council on Pet Population Study and Policy (NCPPSP) is a national research project designed to explore the characteristics of relinquished dogs and cats, their owners, and the reasons for relinquishment. The NCPPSP Regional Shelter Study found that behavioral problems, including aggression toward people or nonhuman animals, were the most frequently given reasons for canine relinquishment and the second most frequently given reasons for feline relinquishment. No association was found between category of relinquishment (behavioral, mixed, nonbehavioral) and gender, number of times mated (males), number of litters (females), purebred status, declaw status, and number of visits to the veterinarian within the past year, for either dogs or cats. Associations were found between category of relinquishment and number of pets in the household, number of pets added to the household, neuter status of female dogs and cats, neuter status of male dogs, ...

TL;DR: In this paper, the authors examined sources of measurement error variance in the Teacher Efficacy Scale (TES), the most frequently used instrument in the area to assess teacher effectiveness, and the reliability generalization was used to characterize the typical score reliability for the TES.
Abstract: Teacher efficacy has proven to be an important variable in teacher effectiveness. It is consistently related to positive teaching behaviors and student outcomes. However, the measurement of this construct is the subject of current debate, which includes critical examination of predominant instruments used to assess teacher efficacy. The present study extends this critical evaluation and examines sources of measurement error variance in the Teacher Efficacy Scale (TES), historically the most frequently used instrument in the area. Reliability generalization was used to characterize the typical score reliability for the TES and potential sources of measurement error variance across studies. Other related instruments were also examined as regards measurement integrity.

TL;DR: Men and women may have different hormonal responses to interaction with their dogs, and it is unclear to what degree OT reactivity was affected by hormones, personality traits, or interpersonal relationships.
Abstract: Oxytocin (OT) is a neuropeptide increasingly recognized for its role in bonding, socialization, and stress relief. Previous research has demonstrated participants' OT levels increased after interacting with or petting a dog, suggesting OT is at least partially responsible for the calm, relaxing feeling that participants experienced during this intervention. The purpose of our study was to more closely examine changes in oxytocin levels in men and women in response to interaction with their own dog after being separated from the dog while at work all day. This condition was compared with a reading control condition, without the presence of the dog. Because the workplace is a common stressor, participants were examined after work to evaluate how interacting with a pet may help decrease stress, as evidenced by increases in serum oxytocin levels. Ten men and ten women participated in the study. Serum oxytocin levels were obtained before the participants had contact with their dogs and then again after...

TL;DR: This paper investigated empirically exactly how dissimilar in both composition and variability samples inducting reliability coefficients from prior studies were from the cited prior samples from which coefficients were generalized, and concluded that reliability, once proven, is immutable.
Abstract: As measurement specialists, we have done a disservice to both ourselves and our profession by habitually referring to “the reliability of the test,” or saying that “the test is reliable.” This has created a mind-set implying that reliability, once proven, is immutable. More important, practitioners and scholars need not know measurement theories if they may simply rely on the reliability purportedly intrinsic within all uses of established measures. The present study investigated empirically exactly how dissimilar in both composition and variability samples inducting reliability coefficients from prior studies were from the cited prior samples from which coefficients were generalized.

TL;DR: This paper examined body image and relationship satisfaction in male and female college students, and found that women were more dissatisfied with their appearance than were men, whereas men were more satisfied with their relationships and sex lives than were women.
Abstract: The purpose of this study was to examine body image and relationship satisfaction in male and female college students. A total of 101 males and 187 females, primarily Caucasian and middle class, completed a questionnaire designed to measure satisfaction with specific body parts, overall body characteristics, and relationship status. These variables were examined in light of gender and body size differences. Results indicated that women, especially those under or above average weight, were more dissatisfied with their appearance than were men, whereas men were more dissatisfied with their relationships and sex lives than were women. In addition, those body parts with which each gender was most dissatisfied were consistent with the body parts emphasized through “ideal” images. These results are discussed in relation to gender role dynamics and societal pressures.

TL;DR: The historical development of a from other indexes of internal consistency (split-half reliability and Kuder-Richardson 20) and four myths associated with a are discussed, including that it is a fixed property of the scale and that higher values are always preferred over lower ones.
Abstract: Cronbach's a is the most widely used index of the reliability of a scale. However, its use and interpretation can be subject to a number of errors. This article discusses the historical development of a from other indexes of internal consistency (split-half reliability and Kuder-Richardson 20) and discusses four myths associated with a: (a) that it is a fixed property of the scale, (b) that it measures only the internal consistency of the scale, (c) that higher values are always preferred over lower ones, and (d) that it is restricted to the range of 0 to 1. It provides some recommendations for acceptable values of a in different situations.

TL;DR: In this paper, the authors present the important concepts required for implementing two disciplines of factor analysis -exploratory factor analysis (EFA) and confirmatory Factor Analysis (CFA) with an emphasis on EFA/CFA linkages.
Abstract: This volume presents the important concepts required for implementing two disciplines of factor analysis - exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with an emphasis on EFA/CFA linkages. Modern extensions of older data analysis methods (e.g., ANOVA, regression, MANOVA, and descriptive discriminant analysis) have brought theory-testing procedures to the analytic forefront. Variations of factor analysis, such as the factoring of people or time, have great potential to inform psychological research. Thompson deftly presents highly technical material in an appealing and accessible manner. The book is unique in that it presents both exploratory and confirmatory methods within the single category of the general linear model (GLM). Canons of best factor analytic practice are presented and explained. An actual data set, generated by 100 graduate students and 100 faculty from the United States and Canada, is used throughout the book, allowing readers to replicate reported results.

TL;DR: Qualitative research in such mobile health clinics has found that patients value the informal, familiar environment in a convenient location, with staff who “are easy to talk to,” and that the staff’s “marriage of professional and personal discourses” provides patients the space to disclose information themselves.
Abstract: www.mobilehealthmap.org 617‐442‐3200 New research shows that mobile health clinics improve health outcomes for hard to reach populations in cost‐effective and culturally competent ways . A Harvard Medical School study determined that for every dollar invested in a mobile health clinic, the US healthcare system saves $30 on average. Mobile health clinics, which offer a range of services from preventive screenings to asthma treatment, leverage their mobility to treat people in the convenience of their own communities. For example, a mobile health clinic in Baltimore, MD, has documented savings of $3,500 per child seen due to reduced asthma‐related hospitalizations. The estimated 2,000 mobile health clinics across the country are providing similarly cost‐effective access to healthcare for a wide range of populations. Many successful mobile health clinics cite their ability to foster trusting relationships. Qualitative research in such mobile health clinics has found that patients value the informal, familiar environment in a convenient location, with staff who “are easy to talk to,” and that the staff’s “marriage of professional and personal discourses” provides patients the space to disclose information themselves. A communications academic argued that mobile health clinics’ unique use of space is important in facilitating these relationships. Mobile health clinics park in the heart of the community in familiar spaces, like shopping centers or bus stations, which lend themselves to the local community atmosphere.

TL;DR: This survey of sexual practices in the United States has been combed by the media for items of interest to the public: monogamous sex is much more widespread in this country than has been thought.
Abstract: This survey of sexual practices in the United States has been combed by the media for items of interest to the public: monogamous sex is much more widespread in this country than has been thought; infidelity is less frequent than presumed; vaginal intercourse is the defining experience of heterosexual behavior; watching one's partner undress is stimulating to many people; married couples have more sex than single people (unmarried, cohabiting couples have the most sex of all); the majority of couples experience sex twice a week to several times a month; 2.8% of men identify themselves as homosexual and 1.4% of women do so, but a higher percentage of people consider a same-gender experience to have some appeal; 75% of men always experience orgasm compared with 28.6% of women, but more nearly equal numbers of men and women declare themselves satisfied with their sexual experiences. The book is, in fact, a
