Julie B Schnur, Matthew J Dillon, Rachel E Goldsmith, Guy H Montgomery
OBJECTIVE: Some 25% of women and 8% of men in the United States have experienced childhood sexual abuse (CSA) before the age of 18. For these individuals, healthcare visits and interactions can be retraumatizing due to perceived similarities to past abuse (e.g., pain, undressing, lack of control). However, no prior studies have provided formal qualitative analyses regarding CSA survivors' reactions to cancer treatment. Therefore, our study's objective was to identify key themes pertaining to CSA survivors' cancer treatment experiences...

OBJECTIVE: Understanding the impact of tobacco marketing on e-cigarette (EC) susceptibility and perceptions is essential to inform efforts to mitigate tobacco product burden on public health. METHODS: Data were collected online in 2016 from 634 conventional cigarette (CC) smokers and 393 non-smokers using a convenience sample from Amazon Mechanical Turk. Logistic regression models, stratified by smoking status and adjusted for socio-demographics, examined the relationship among tobacco advertisements and coupons, EC and CC susceptibility, and EC perceptions...

The field of gambling studies has extensively focused on isolating risk factors for developing a gambling disorder. Conversely, little attention has been paid to identifying protective factors against gambling disorder among people who choose to not gamble at all. Moreover, the limited number of studies that have focused on non-gamblers have neglected to differentiate current from lifetime non-gamblers. The purpose of the present study was to examine motives for not gambling among a diverse sample of adult lifetime non-gamblers recruited from the community and to compare these motives to an undergraduate student sample of non-gamblers from a previous study...

This article reports on the development of a new self-report questionnaire measure of schizotypy - the Multidimensional Schizotypy Scale (MSS). Schizotypy offers a useful and unifying construct for understanding schizophrenia-spectrum psychopathology. Questionnaire measures have been widely used to assess schizotypy and have greatly informed our understanding of the construct. However, available measures suffer from a number of limitations, including lack of a clear conceptual framework, outdated wording, unclear factor structure, and psychometric shortcomings...

In order to reconstruct environments associated with Plio-Pleistocene hominins in southern Africa, researchers frequently rely upon the animals associated with the hominins, in particular, animals in the Family Bovidae. Bovids in southern Africa are typically identified by their teeth. However, identifying the taxon of a bovid tooth is challenging due to various biasing factors. Furthermore, inaccurate identification of fossil bovids can have significant consequences on the reconstructed paleoenvironment. Recent research on the classification of bovid fossil teeth has relied on using elliptical Fourier analysis to summarize the shape of the outline of the occlusal surface of the tooth and the resulting harmonic amplitudes...

Suicide is ranked as the tenth leading cause of death for all ages in the United States (Centers for Disease Control and Prevention, 2012). Joiner's (2005) interpersonal theory of suicide stated thwarted belongingness-the feeling of being alienated from others-and perceived burdensomeness-the feeling of being a liability to others-are the primary proximal factors leading to suicidal desire. The current study focused on thwarted belongingness and examined its relationship to face-to-face interactions and online interactions in both an undergraduate and community sample...

Systematic reviews are increasingly used to inform health care decisions, but are expensive to produce. We explore the use of crowdsourcing (distributing tasks to untrained workers via the web) to reduce the cost of screening citations. We used Amazon Mechanical Turk as our platform and 4 previously conducted systematic reviews as examples. For each citation, workers answered 4 or 5 questions that were equivalent to the eligibility criteria. We aggregated responses from multiple workers into an overall decision to include or exclude the citation using 1 of 9 algorithms and compared the performance of these algorithms to the corresponding decisions of trained experts...

BACKGROUND AND AIMS: Probability discounting refers to the effect of outcome uncertainty on decision making. Using probability discounting, we examined the degree to which self-identified chronic pain patients (CPP) were likely to try a novel analgesic medication given increasing addiction risk. We postulated that propensity for opioid misuse, trait impulsivity, and previous opioid experience would be positively associated with likelihood of risky medication use. DESIGN: This cross-sectional online study determined state/trait associations with addiction-related medication decisions in CPP...

Prior research with preschool children has established that dialogic or active book reading is an effective method for expanding young children's vocabulary. In this exploratory study, we asked whether similar benefits are observed when a robot engages in dialogic reading with preschoolers. Given the established effectiveness of active reading, we also asked whether this effectiveness was critically dependent on the expressive characteristics of the robot. For approximately half the children, the robot's active reading was expressive; the robot's voice included a wide range of intonation and emotion (Expressive)...

BACKGROUND: Diabetic retinopathy (DR) is a leading cause of vision loss in working age individuals worldwide. While screening is effective and cost effective, it remains underutilized, and novel methods are needed to increase detection of DR. This clinical validation study compared diagnostic gradings of retinal fundus photographs provided by volunteers on the Amazon Mechanical Turk (AMT) crowdsourcing marketplace with expert-provided gold-standard grading and explored whether determination of the consensus of crowdsourced classifications could be improved beyond a simple majority vote (MV) using regression methods...

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...

Gambling is a serious concern for society because it is highly addictive and is associated with a myriad of negative outcomes. The current study applied the Reasoned Action Model (RAM) to understand and predict gambling intentions and behavior. Although prior studies have taken a reasoned action approach to understand gambling, no prior study has fully applied the RAM or used the RAM to predict future gambling. Across two studies the RAM was used to predict intentions to gamble, past gambling behavior, and future gambling behavior...

The link between early initiation and problematic use has been observed for substance use disorders; however, this link has not been as clearly established for Internet gaming disorder (IGD). Available studies indicate that individuals who initiate Internet use at younger ages exhibit an increased risk for general Internet addiction. Prior research also suggests unique cognitive processes in online gaming, such that an individual's overall sense of self-worth can become contingent upon self-esteem derived from the gaming environment...

Insomnia is robustly associated with suicidal behavior, but methodological limitations in existing studies hinder nuanced understanding of this relationship. The current study addressed these limitations by utilizing a longitudinal design and advanced statistical modeling. Participants who endorsed lifetime experience of suicidal behavior were recruited through Amazon's Mechanical Turk (N = 589) and completed self-report online surveys at 6 time points over a 15-day period. Latent difference score modeling was utilized to investigate whether levels and/or changes in insomnia symptoms drive subsequent changes in suicide ideation, or vice versa...

BACKGROUND: Models measuring the interactions between consumption of conventional cigarettes and electronic cigarettes (e-cigarettes) in the marketplace are becoming vital forecast tools as the popularity of e-cigarettes increases and policy on tobacco products changes. Behavioral economics, which involves the integration of psychology and consumer demand, can be used to measure individuals' purchase behavior under different marketplace conditions. Our goal was to measure hypothetical conventional cigarette and e-cigarette purchasing among smokers with varying e-cigarette use patterns...

The current study examined relational aggression as a potential mechanism that explains the association between off-time pubertal development and internalizing problems in youth. Youth gender was also examined as a moderator for the association between these variables. It was hypothesized that early pubertal maturation would be associated with higher levels of relationally aggressive behavior which, in turn, would be associated with elevated levels of internalizing problems. Parents of 372 children between the ages of 8 and 17 were recruited through Amazon's Mechanical Turk...

Accumulating laboratory-based evidence indicates that reducing delay discounting (devaluation of delayed outcomes) with the use of episodic future thinking (EFT; mental simulation of future events) improves dietary decision-making and other maladaptive behaviors. Recent work has adapted EFT for use in the natural environment to aid in dietary and weight control by engaging participants in EFT repeatedly throughout the day. These efforts may benefit from minimizing the amount of time required for measurement and implementation of EFT...

Bayesian truth serum (BTS) is an exciting new method for improving honesty and information quality in multiple-choice survey, but, despite the method's mathematical reliance on large sample sizes, existing literature about BTS only focuses on small experiments. Combined with the prevalence of online survey platforms, such as Amazon's Mechanical Turk, which facilitate surveys with hundreds or thousands of participants, BTS must be effective in large-scale experiments for BTS to become a readily accepted tool in real-world applications...
