BACKGROUND: Amazon's Mechanical Turk (MTurk) platform has become a data source for peer-reviewed academic research publications, with over 24,000 Google Scholar search results. Although well-developed and supportive in other disciplines, the literature in health and medicine comparing results from samples generated on MTurk to gold standard, nationally representative health and medical surveys is beginning to emerge. OBJECTIVE: To compare the demographic, socioeconomic, and self-reported health status variables in an MTurk sample to those from 2 prominent national probability surveys, including the Medical Expenditure Panel Survey (MEPS) and the Behavioral Risk Factor Surveillance System (BRFSS)...

A series of self-report measures of personality disorder from the perspective of the five-factor model (FFM) have been published; however, no informant-report versions have been developed. An informant version of the Five Factor Narcissism Inventory (FFNI) is particularly apt, given the degree of distortion in self-description inherent to narcissism. The present study provides initial validation for the Informant Five-Factor Narcissism Inventory (IFFNI). In Study 1, informant reports from friends, romantic partners, parents, and other family members were compared with self-reports provided by undergraduate college students on the IFFNI, FFM personality, and social dysfunction...

Megan L Rogers, Thomas E Joiner
Suicide-specific rumination, defined as a mental fixation on one's suicidal thoughts, intentions, and plans, may be an important predictor of suicidal behavior. To date, suicide-specific rumination has demonstrated convergence with, yet distinction from, a variety of suicide risk factors, and differentiated suicide attempters from ideators. However, no research has examined whether suicide-specific rumination is associated with lifetime suicide attempts above and beyond the presence of a host of other relevant suicide risk factors...

INTRODUCTION: Many e-cigarette users find the variety of e-cigarette flavors appealing. We examined whether preferences for e-liquid flavors and the total number of flavors preferred differed between samples of adolescent and adult e-cigarette users. We also examined whether these preferences were associated with e-cigarette use frequency for adolescents or adults, respectively. MATERIALS AND METHODS: The analytic samples comprised 1) 396 adolescent, past-month e-cigarette users from 5 Connecticut high schools who completed an anonymous, school-based survey in Fall 2014 (56...

BACKGROUND: Prevention researchers have identified parental monitoring leading to parental knowledge to be a protective factor against adolescent substance use. In today's digital society, parental monitoring can occur using technology-mediated communication methods, such as text messaging, email, and social networking sites. OBJECTIVES: The current study aimed to identify patterns, or clusters, of in-person and technology-mediated monitoring behaviors, and examine differences between the patterns (clusters) in adolescent substance use...

Crowdsourcing services, such as MTurk, have opened a large pool of participants to researchers. Unfortunately, it can be difficult to confidently acquire a sample that matches a given demographic, psychographic, or behavioral dimension. This problem exists because little information is known about individual participants and because some participants are motivated to misrepresent their identity with the goal of financial reward. Despite the fact that online workers do not typically display a greater than average level of dishonesty, when researchers overtly request that only a certain population take part in an online study, a nontrivial portion misrepresent their identity...

BACKGROUND: There has been a sharp increase in the number of pedestrians injured while using a mobile phone, but little research has been conducted to explain how and why people use mobile devices while walking. Therefore, we conducted a survey study to explicate the motivations of mobile phone use while walking. OBJECTIVE: The purpose of this study was to identify the critical predictors of behavioral intention to play a popular mobile game, Pokemon Go, while walking, based on the theory of planned behavior (TPB)...

BACKGROUND: Mechanical Turk (MTurk) is an online portal operated by Amazon where 'requesters' (individuals or businesses) can submit jobs for 'workers.' MTurk is used extensively by academics as a quick and cheap means of collecting questionnaire data, including information on alcohol consumption, from a diverse sample of participants. We tested the feasibility of recruiting for alcohol Internet intervention trials through MTurk. METHODS: Participants, 18 years or older, who drank at least weekly were recruited for four intervention trials (combined sample size, N = 11,107)...

Although decades of research show that people tend to see themselves in the best possible light, we present evidence that people have a surprisingly grim outlook on their social lives. In 11 studies (N = 3,293; including 3 preregistered), we find that most people think that others lead richer and more active social lives than they do themselves. We show that this bias holds across multiple populations (college students, MTurk respondents, shoppers at a local mall, and participants from a large, income-stratified online panel), correlates strongly with well-being, and is particularly acute for social activities (e...

BACKGROUND: Families face many barriers related to creating or maintaining a healthy lifestyle, which likely contributes to the prevalence of childhood obesity in the United States; however, no measure currently exists to examine these barriers. This study developed a quantitative measure of parents' perceptions of barriers to family healthy lifestyle. METHODS: Parents of children between the ages of 7-17 were recruited using Amazon Mturk (n = 812). Exploratory and confirmatory factor analyses and preliminary convergent validity analyses were conducted...

Cognitive and affective antecedents of the desire to avoid or punish non-offending pedophilic individuals are not well understood. In this article, we examined the effects of non-offending motivation (internal vs. external) and sexual orientation (pedophilic vs. teleiophilic) on cognitive apprehensions (amorality, dangerousness, abnormality), emotions (fear, anger, disgust), punitive attitudes, and social distance toward a man experiencing a sexually transgressive impulse. A total of 205 U.S.-based MTurk workers were randomly assigned to one of four groups in this 2 × 2 factorial vignette study...

INTRODUCTION: Cost-utility analyses (CUA) are useful when the treatment conditions depend on patient preferences that are in turn dependent on health state utility value. Spina bifida (SB) is an example of such a preference-sensitive condition. Historically, the SB utility value for CUA has been gathered via a traditional face-to-face interview. However, due to funding and time constrains, utility estimation via online crowdsourcing has recently gained popularity. Our aim was to estimate the utility value for a generic SB health state using a validated online tool...

In judging normalcy, surgeons rely on established facial anthropometric measures and proportions. However, there exists a range of "normal," and a degree of disproportion may be considered more attractive. The authors set out to determine how changes in only intercanthal distance affect the layperson's perception of beauty and personality traits of a face. The authors used Amazon.com's Mechanical Turk (MTurk), a crowdsourcing tool, to determine how changes in intercanthal distance affect overall perception of beauty and personality...

BACKGROUND: The effects of orthognathic surgery go beyond objective cephalometric correction of facial and dental disproportion and malocclusion, respectively. The authors hypothesized that there is tangible improvement following surgery that alters publicly perceived personality traits and emotions. METHODS: The authors used Amazon.com's Mechanical Turk (MTurk), a crowdsourcing tool, to determine how preoperative and postoperative images of orthognathic surgery patients were perceived on six personality traits and six emotional expressions based on posteroanterior and lateral photographs...

OBJECTIVE: High rates of sexually transmitted infections (STIs) and unintended pregnancy suggest a role for multipurpose prevention technologies (MPTs) designed to combine contraception and infection prophylaxis into one unified method. This study aims to determine factors associated with interest in MPTs among US women. STUDY DESIGN: We administered a national cross-sectional survey via MTurk. Eligibility criteria included female gender, age 18-29 years, residence in the USA, and sexual activity with a male partner in the past three months...

Common mental health consequences following the experience of potentially traumatic events include Posttraumatic Stress Disorder (PTSD) and addictive behaviors. Problematic smartphone use is a newer manifestation of addictive behaviors. People with anxiety severity (such as PTSD) may be at risk for problematic smartphone use as a means of coping with their symptoms. Unique to our knowledge, we assessed relations between PTSD symptom clusters and problematic smartphone use. Participants (N = 347), recruited through Amazon's Mechanical Turk (MTurk), completed measures of PTSD and smartphone addiction...

BACKGROUND: The involvement of patients in research better aligns evidence generation to the gaps that patients themselves face when making decisions about health care. However, obtaining patients' perspectives is challenging. Amazon's Mechanical Turk (MTurk) has gained popularity over the past decade as a crowdsourcing platform to reach large numbers of individuals to perform tasks for a small reward for the respondent, at small cost to the investigator. The appropriateness of such crowdsourcing methods in medical research has yet to be clarified...

Nathan Miller, Frances Prevatt
OBJECTIVE: The purpose of this study was to reexamine the latent structure of ADHD and sluggish cognitive tempo (SCT) due to issues with construct validity. Two proposed changes to the construct include viewing hyperactivity and sluggishness (hypoactivity) as a single continuum of activity level, and viewing inattention as a separate dimension from activity level. METHOD: Data were collected from 1,398 adults using Amazon's MTurk. A new scale measuring activity level was developed, and scores of Inattention were regressed onto scores of Activity Level using curvilinear regression...
