Cocaine addiction is a multi-dimensional behavioral disorder characterized by a loss of control over cocaine taking despite of detrimental consequences. Structural MRI studies have revealed association between cocaine consumption and gray matter volume (GMV) in cocaine-addicted patients. However, the behavioral correlates of GMV in cocaine addiction are poorly understood. Here, we used a DSM-IV-based rat model of cocaine addiction with high face validity for structural imaging. According to three behavioral sub-dimensions of addiction, rats were separated into two groups showing either addict-like or non-addict-like behavior...

Radiotherapy of lung and liver lesions has changed from normofractioned 3D-CRT to stereotactic treatment in a single or few fractions, often employing volumetric arc therapy (VMAT)-based techniques. Potential unintended interference of respiratory target motion and dynamically changing beam parameters during VMAT dose delivery motivates establishing 4D quality assurance (4D QA) procedures to assess appropriateness of generated VMAT treatment plans when taking into account patient-specific motion characteristics...

Citizen science enables volunteers to contribute to scientific projects, where massive data collection and analysis are often required. Volunteers participate in citizen science activities online from their homes or in the field and are motivated by both intrinsic and extrinsic factors. Here, we investigated the possibility of integrating citizen science tasks within physical exercises envisaged as part of a potential rehabilitation therapy session. The citizen science activity entailed environmental mapping of a polluted body of water using a miniature instrumented boat, which was remotely controlled by the participants through their physical gesture tracked by a low-cost markerless motion capture system...

A major success in personality has been the development of a consensual structure of traits. However, much less progress has been made on the structure of an equally important aspect of human psychology: motives. We present an empirically and theoretically structured hierarchical taxonomy of 161 motives gleaned from a literature review from McDougall to the present and based on the cluster analysis of similarity judgments among these 161 motives, a broader sampling of motives than previous work. At the broadest level were: Meaning, Communion, and Agency...

Several studies in different countries have been conducted to investigate factors affecting food choices. The objective of this study was to understand the motivations of specific food and beverage choices for different eating occasions in a typical diet of the Turkish people. A convenience sample of 141 respondents from seven different geographical regions in Turkey completed an online survey questionnaire that included questions about demographic information and details about their latest eating occasion...

Childhood obesity has reached epidemic proportions and is linked to hypertension among African American youth. Optimistic bias influences behavior of youth causing them to underestimate their susceptibility to negative health outcomes. This study explored adolescent behaviors and prevalence of high blood pressure and obesity in a school district. We examined the relationship between individual health risk practices and optimistic bias on health outcomes; 433 African American high school students were administered a survey and had their obesity and blood pressure measured by the school nurse...

BACKGROUND: Adverse medical events (AMEs) pose serious threats to patient safety. One of the major challenges of AME reporting is low physician engagement. This study attempted to examine how punishment and reward can improve physicians' AME reporting in China. METHODS: A survey was conducted in a large hospital with 1693 beds in China. Data were collected from 311 physicians. Ordinal and binary logistic regression was used for data analysis. RESULTS: This study reveals that both punishment and reward are positively associated with intention to report AMEs...

The author explores the nature of hypnosis, which he characterizes as a motivated mode of neural functioning that enables most humans to alter, to varying degrees, their experience of body, self, actions, and world. The essence of hypnosis is not to be found in hetero-hypnosis; instead, it lies in the spontaneous self-activation of that mode of neural functioning. The hypnosis field has substantially lost sight of spontaneous self-activation, because the word hypnosis is usually used to mean hetero-hypnosis...

Research based on the Eccles model of parent socialization demonstrated that parents are an important source of value and ability information for their children. Little is known, however, about the bidirectional effects between students' perceptions of their parents' beliefs and behaviors and the students' own domain-specific values. This study analyzed how students' perceptions of parents' beliefs and behaviors and students' mathematics values and mathematics-related career plans affect each other bidirectionally, and analyzed the role of students' gender as a moderator of these relations...

This study examined mostly lower-middle-income Latino (37%) and African American (33%) adolescents' (N = 90, Mage = 15.90) conceptions of how U.S. wealth is and ought to be distributed, and whether these judgments are related to adolescents' views about societal and legal fairness and their immediate academic plans. Individually administered multipart interviews assessed conceptions regarding (a) actual and ideal U.S. wealth distribution and related "Rawlsian" judgments, (b) social system and legal fairness, and (c) adolescents' near-term life goals...

The effect of scientific training on course learning in undergraduates is still controversial. In this study, we investigated the academic performance of undergraduate students with and without scientific training. The results show that scientific training improves students' test scores in general medical courses, such as biochemistry and molecular biology, cell biology, physiology, and even English. We classified scientific training into four levels. We found that literature reading could significantly improve students' test scores in general courses...

BACKGROUND: Individuals with schizophrenia engage in goal-directed activities significantly less often compared to healthy individuals in the community. There is ample evidence documenting the presence of motivational deficits in schizophrenia using observer-based ratings; however, purely self-reported accounts of patients' motivation are less well understood. This study examined subjective accounts of trait achievement motivation among relatively young, clinically stable, early-course outpatients with schizophrenia...

INTRODUCTION: Adherence to medicines is vital in treating diseases. Initial medication non-adherence (IMNA) - defined as not obtaining a medication the first time it is prescribed - has been poorly explored. Previous studies show IMNA rates between 6 and 28% in Primary Care (PC). The aims of this study were to determine prevalence and predictive factors of IMNA in the most prescribed and expensive pharmacotherapeutic groups in the Catalan health system. METHODS: Retrospective, register-based cohort study which linked Catalan PC System (Spain) prescription and invoicing databases...

Dawn K Wilson, Allison M Sweeney, Heather Kitzman-Ulrich, Haylee Gause, Sara M St George
Nurturing environments within the context of families, schools, and communities all play an important role in enhancing youth's behavioral choices and health outcomes. The increasing prevalence rates of obesity among youth, especially among low income and ethnic minorities, highlight the need to develop effective and innovative intervention approaches that promote positive supportive environments across different contexts for at-risk youth. We propose that the integration of Social Cognitive Theory, Family Systems Theory, and Self-Determination Theory offers a useful framework for understanding how individual, family, and social-environmental-level factors contribute to the development of nurturing environments...

RATIONALE: The negative affective state, e.g., anhedonia, emerges after abstinence from abused drugs may be linked to the motivational processes of drug craving and relapse. Although anhedonia diminishes over time with drug abstinence, it is not yet rather explicit whether anhedonia exists or not following protracted withdrawal. OBJECTIVES: The behavioral responses to natural rewards were examined after 2 to 3 weeks withdrawal from morphine. Male rats were pretreated with either a binge-like morphine paradigm or daily saline injection for 5 days...

Medication adherence is poor among pediatric cystic fibrosis (CF) patients, with adolescents having one of the lowest adherence rates. We wanted to identify an adherence intervention that would be acceptable to CF adolescents and assess its feasibility. We surveyed 40 adolescents with CF and asked about barriers to and motivators for their own adherence and to generate ideas for potential adherence interventions. Since most of the respondents chose frequent spirometry at home and medication reminders for interventions, we selected 5 subjects, 10 to 14 years of age, with CF to test the feasibility of home spirometry and medication reminders in pediatric CF patients...

We study the relationship among real, self-perceived, and desired body mass index (BMI) in 21,288 adults from the Mexican National Health and Nutrition Survey 2012, analyzing the effect of sex and diagnosis of obesity/overweight by a healthcare professional. Self-perceived and desired BMI are analyzed via a figure rating scale question and compared to real BMI. Only 8.8 and 6.1% of the diagnosed and non-diagnosed obese, respectively, correctly identify themselves as such. For the obese, 20.2% of non-diagnosed and 12...
