Two studies investigated the effectiveness of a self-affirmation exercise on vaccine safety beliefs and intent to vaccinate future children. In Study 1, a sample of 585 parents with at least one child under the age of 18 in the home participated through Amazon's MTurk. Participants were randomly assigned to one of four conditions in a 2 x 2 design. Participants read either correcting information refuting a link between the measles, mumps, and rubella (MMR) vaccine and autism or a control passage about bird feeding...

The current study used the Health Belief Model to develop a measure that assessed the emotional benefits and barriers of professional psychological services in an African American women sample. Data from 251 African American women recruited from online organizations from across the United States (n = 164) and a Midwestern university psychology subject pool (n = 87) were used for exploratory factor analysis. Results revealed a 2-factor structure of the Emotional Benefits and Barriers of Psychological Services (EBBPS) Scale: Life Enhancement and Concerns about Distress, respectively...

The atmospheric residence time of carbon dioxide is hundreds of years, many orders of magnitude longer than that of common air pollution, which is typically hours to a few days. However, randomly selected respondents in a mail survey in Allegheny County, PA (N = 119) and in a national survey conducted with MTurk (N = 1,013) judged the two to be identical (in decades), considerably overestimating the residence time of air pollution and drastically underestimating that of carbon dioxide. Moreover, while many respondents believed that action is needed today to avoid climate change (regardless of cause), roughly a quarter held the view that if climate change is real and serious, we will be able to stop it in the future when it happens, just as we did with common air pollution...

BACKGROUND: Several barriers exist in the recruitment of individuals with a history of mild traumatic brain injury (mTBI). The current study is the first to examine whether crowdsourcing, which has been used in other clinical populations, is useful in the recruitment of those with mTBI. OBJECTIVE: To examine whether Amazon's Mechanical Turk (MTurk), an online crowdsourcing platform, is a useful tool in the recruitment of individuals with a history of mTBI and to examine the injury and psychological characteristics of individuals who report a history of mTBI...

Online crowdsourcing websites such as Amazon's Mechanical Turk (MTurk) are increasingly being used in addictions research. However, there is a relative paucity of such research examining the validity of administering behavioral economic alcohol-related measures, via an online crowdsourcing platform. This study sought to validate an alcohol purchase task (APT) for assessing demand and a questionnaire measure of proportionate alcohol reinforcement, using an online sample of participants recruited via MTurk. Participants (N = 865, 59% female) were recruited via MTurk to complete the APT, proportionate alcohol reinforcement questionnaire, Alcohol Use Disorders Identification Test (AUDIT), and demographics...

BACKGROUND: Social media technologies offer a novel opportunity for scalable health interventions that can facilitate user engagement and social support, which in turn may reinforce positive processes for behavior change. OBJECTIVE: By using principles from health communication and social support literature, we implemented a Facebook group-based intervention that targeted smoking reduction and cessation. This study hypothesized that participants' engagement with and perceived social support from our Facebook group intervention would predict smoking reduction...

OBJECTIVE: Theoretical conceptions of narcissism have long been characterized by two seemingly opposing poles: grandiosity and vulnerability. The goal of the current study was to investigate the extent to which traits associated with one profile are perceived to co-occur with the other within an individual. METHOD: Lay raters (n = 862; 56% female; 80% Caucasian; mean age = 37) recruited from Amazon's MTurk and assigned to one of four conditions in which they rated how often a series of narcissistic traits were displayed by a prototypical grandiose narcissist, vulnerable narcissist, a close friend, or themselves...

OBJECTIVE: There is no empirical information about how parents react when they discover that their young children have seen pornography. To address this gap in the literature, the current study sought to improve our understanding of parental reactions to discovering that their children ages <12 years old have seen pornography using a mixed-methods approach. METHODS: A convenience sample of participants (N = 279) was recruited from the online survey service Mechanical Turk...

Playing drinking games can be characterized as a high-risk drinking activity because games are typically designed to promote heavy alcohol consumption. While research suggests that young adults are motivated to play drinking games for a variety of reasons (e.g., for thrills/fun, for the competition), the Motives for Playing Drinking Games measure has received limited empirical attention. We examined the psychometric properties of this measure with a confirmation sample of young adults recruited from Amazon's MTurk ( N = 1,809, ages 18-25 years, 47% men; 41% not currently enrolled in college) and a validation sample of college students ( N = 671; ages 18-23 years; 26% men)...

Recent research on human behavior has often collected empirical data from the online labor market, through a process known as crowdsourcing. As well as the United States and the major European countries, there are several crowdsourcing services in Japan. For research purpose, Amazon's Mechanical Turk (MTurk) is the widely used platform among those services. Previous validation studies have shown many commonalities between MTurk workers and participants from traditional samples based on not only personality but also performance on reasoning tasks...

Pornography may be a construct with a single trait or one with many traits. Research in the past was inconsistent in this regard with most researchers assuming that pornography was unidimensional (with one single trait of pornography). However, the considerable amounts of residual variation found in these studies beyond that explained by the single trait hints at what might be a multidimensional construct (with multiple traits such as sensitization and differentiation). Consequently, in this study, we intended to address the question of whether pornography consisted of a single trait or if it was multidimensional...

Recruitment for HIV research among gay, bisexual, and other men who have sex with men (MSM) has increasingly moved to the online sphere. However, there are limited data comparing the characteristics of clinic-based respondents versus those recruited via online survey platforms. MSM were recruited from three sampling sites (STI clinic, MTurk, and Qualtrics) to participate in a survey from March 2015 to April 2016. Respondents were compared between each of the sampling sites on demographics, sexual history, substance use, and attention filter passage...

Proposed for the 11th edition of the World Health Organization's International Classification of Diseases (ICD-11) is a dimensional trait model for the classification of personality disorder (Tyrer, Reed, & Crawford, 2015). The ICD-11 proposal consists of 5 broad domains: negative affective, detachment, dissocial, disinhibition, and anankastic (Mulder, Horwood, Tyrer, Carter, & Joyce, 2016). Several field trials have examined this proposal, yet none has included a direct measure of the trait model. The purpose of the current study was to develop and provide initial validation for the Personality Inventory for ICD-11 (PiCD), a self-report measure of this proposed 5-domain maladaptive trait model...

BACKGROUND: Overlapping surgery is highly contentious, both in terms of the safety of the practice and the degree to which patients should be informed. However, no study has surveyed attitudes of the general public toward overlapping surgery and willingness to consent to such a procedure. STUDY DESIGN: A survey on overlapping surgery was completed by participants using Amazon Mechanical Turk, an online crowd-sourcing worksite. Responders completed a 51-question survey on their knowledge of overlapping surgery, expectations on disclosure during the informed consent process, and their willingness to participate in such a procedure...

35 Background: Many patients with acute myeloid leukemia (AML) face a difficult choice about whether to receive palliative chemotherapy or high-dose, potentially-curative chemotherapy that poses a risk of early death. How people weigh these factors in decision-making is unknown. We hypothesized that the possibility of cure primarily drives decision-making, regardless of treatment risk. METHODS: We designed an electronic survey describing two treatment paths: (1) high-dose chemotherapy with possibility of cure but a 10% risk of early death, and (2) palliative chemotherapy with no chance of cure but no risk of early death...

Testing infants in the laboratory is expensive in time and money; consequently, many studies are underpowered, reducing their reproducibility. We investigated whether the online platform, Amazon Mechanical Turk (MTurk), could be used as a resource to more easily recruit and measure the behavior of infant populations. Using a looking time paradigm, with users' webcams we recorded how long infants aged 5 to 8months attended while viewing children's television programs. We found that infants (N=57) were more reliably engaged by some movies than by others and that the most engaging movies could maintain attention for approximately 70% of a 10- to 13-min period...

The world population has doubled over the last half century. Yet, research on the psychological effects of human population density, once a popular topic, has decreased over the past few decades. Applying a fresh perspective to an old topic, we draw upon life history theory to examine the effects of population density. Across nations and across the U.S. states (Studies 1 and 2), we find that dense populations exhibit behaviors corresponding to a slower life history strategy, including greater future-orientation, greater investment in education, more long-term mating orientation, later marriage age, lower fertility, and greater parental investment...

OBJECTIVE: This study examined the relationship between mindful feeding as a novel construct and parent-reported child dietary intake. METHODS: Participants (N=497) were parents of children ages 2.9 to 7.5 recruited through Amazon Mechanical Turk (MTurk). Parents were primarily non-Hispanic white (79%) and female (76%). Simple and hierarchical regression analyses were conducted to examine the associations between parental mindful feeding (i.e., parent mental and emotional presence while feeding a child) and their children's dietary intake...

The use of crowdsourcing platforms such as Amazon's Mechanical Turk (MTurk) for data collection in the behavioral sciences has increased substantially in the past several years due in large part to (a) the ability to recruit large samples, (b) the inexpensiveness of data collection, (c) the speed of data collection, and (d) evidence that the data collected are, for the most part, of equal or better quality to that collected in undergraduate research pools. In this review, we first evaluate the strengths and potential limitations of this approach to data collection...

Researchers recently have begun using Mechanical Turk (MTurk), an online crowdsourcing platform, to recruit addiction populations. However, whether the data obtained from substance users and gamblers on MTurk are reliable and valid is unknown. Herein, we assessed the internal and retest reliability of and concurrent and convergent validity of data obtained from addiction populations on MTurk. Current drinkers (N = 208), cannabis users (N = 200), and gamblers (N = 200) residing in the United States completed measures of alcohol, cannabis, and gambling severity, psychological constructs (e...
