Self-perceived weight status, dieting and unhealthy weight-control behaviors among Spanish male adolescents

Introduction: Self-perceived weight status among adolescents has been associated with weight-control behaviors. However, this relationship varies across weight status. Objectives: The aim of this study was to examine the effect of self-perceived weight status on dieting and unhealthy weight-control behaviors among Spanish male adolescents, across weight status. Method: Participants were 597 Spanish male adolescents (M = 13.94 years old, SD = 0.60). Body weight and height were measured in situ. Self-perceived weight status, dieting, and unhealthy weight-control behaviors were evaluated. Results: The adolescents were inaccurate on estimating their weight status. Those who were overweight or obese, or who perceived themselves to be so, were more likely to report dieting and unhealthy weight-control behaviors. Discussion: There is a need to promote healthier eating behaviors among adolescents, and to take into account the fact that self-perceived weight status may hinder the adoption of such behaviors.

A communication partner training program: Assessing conversational behaviors and attitudes towards communication in Persons with Aphasia and their Communication Partners

This study examined the conversational behaviors of eleven dyads consisting of a person with aphasia (PWA) and their familiar communication partner (CP), and investigated changes in behaviors as a result of attending a communication partner-training program CPT). Attitudes about communication were examined and related to conversational behaviors observed pre- and post- training. Results indicated that CPs and PWA used significantly more facilitating behaviors than barrier behaviors, although most dyads experienced some barriers. A comparison of pre-and post-CPT conversations revealed a significant interaction between time and type of behavior, with the increase in the number of facilitators approaching significance. Overall, persons with aphasia and their conversational partners expressed positive attitudes about communication. There were no significant correlations between scores on attitude surveys and behaviors pre or post-training. This study demonstrated that these dyads employed facilitative conversational behaviors even before CPT, and that facilitative behaviors can increase after a one-day training workshop.

An interpretative phenomenological analysis of the lived experience of suicidal behaviour

Background: In Scotland, suicide prevention is a major public health challenge, with two people, on average, dying every day due to suicide. Any efforts to prevent suicide should be aided by research. Existing research on suicide is dominated by quantitative research that has largely focused on providing explanatory accounts of suicidal phenomena. Research providing rich and detailed accounts of suicidal behaviour among individuals who have directly experienced it is growing but remains relatively embryonic. This study sought to supplement existing understanding of attempted suicide specifically by exploring the processes, meaning and context of suicidal experiences among individuals with a history of attempted suicide. Methods: The study used a retrospective qualitative design with semi-structured in-depth interviews. Participants were patients (n=7) from a community mental health service in Glasgow, Scotland who had attempted suicide within the previous 12-month period. The interviews were transcribed verbatim and were analysed for recurrent themes using interpretative phenomenological analysis (IPA). Results: Three super-ordinate themes, each with inter-related sub-themes, emerged from the analysis. 1) “Intentions”: This theme explored different motives for suicide, including providing relief from upsetting feelings; a way of establishing control; and a means of communicating with others. 2) “The Suicidal Journey”: This theme explored how individuals’ thinking can change when they are suicidal, including feeling overwhelmed by a build-up of distress and a narrowing of their perspective. 3) “Suicidal Dissonance”: This theme explored how people can feel conflicted about suicide and can be fearful of the consequences of their suicidal behaviour. Conclusion: Participants’ accounts were dominated by experience of significant adversity and psychological suffering. These accounts provided valuable insights into the suicidal process, highlighting implications for clinical practice and future research.

Attachment patterns and suicidal behaviours on higher education students

Introduction: Every individual has a necessity to establish affective relationships throughout life in order to feel comfort and support. This need is called attachment and allows the human being to explore the world, acquiring knowledge about himself and everyone else(1) There are several changes that occur on students’ lives when enrolling and attending university, a period that is known to include a set of situational and academic transitions which might lead to mental health problems, and thus making students more vulnerable and more prone to develop suicidal behaviours. Objectives: To determine the prevalence of suicidal ideation on higher education students and to assess its relationship with attachment patterns. Methods: Quantitative, descriptive and correlational study, applied on a sample of 1074 students from a Portuguese higher education institution. Data collection was possible through an online platform that included a survey with questions regarding sociodemographical and academic profiling, the Portuguese version of the Adult Attachment Scale (EVA)(2) and the Suicidal Ideation Questionnaire(3) Results: Students’ age varies between the 17 and 49 ( = 23,9 years old ± 6,107 Sd), the vast majority (64.7%) are females. Results show that the presence/severity of suicidal thoughts is low ( = 13.84; ± 20.29 Sd) on a scale from 0 to 180 and cut-off point > 41 for values that suggest potential suicidal risk, and based on that, 84 students were identified (7,8%). We verified significant relationships between suicidal ideation and anxiety and attachment (r=0.314 p=0.000). Conclusions: Although there is not a high prevalence of suicidal ideation on students, we found 84 students in our sample (7,8%) that reveal a potential risk for suicide. The results also show that young students with safe attachment patterns display less suicidal ideation. Safe attachment patterns are essential on interpersonal and social relationships and play an important role during the academic period. We cannot be indifferent towards this issue due to its individual, familiar and social repercussions. Every higher education institution should then establish student support offices and develop mental health promotion programs as well as suicide prevention campaigns.

Perceptions and risky behaviors associated with Leptospirosis in an endemic area in a village of Ubon Ratchathani Province, Thailand.

Background: Leptospirosis, a disease caused by Leptospira species, a spirochaete bacterium that can develop in an appropriate environment and/or grow in human and/or animal hosts, is a serious problem for the Ministry of Public Health, Thailand. Objective: To investigate people’s perceptions and behavioral risks regarding leptospirosis infection. Methods: The cross-sectional descriptive study collected data in May, 2013. Data on individuals’ perceptions and risky behaviors concerning leptospirosis were collected from 104 completed questionnaires. Results: Regarding perceptions of leptospirosis, we found them to be at a high level (97.1%) and risky behaviors regarding leptospirosis were reported at a moderate level (74.0%). The study found no correlation between perceptions and risky behaviors regarding leptospirosis (r 0.186, p-value 0.059). Conclusion: This study suggest that people in these areas have good knowledge about leptospirosis. However, some people have risky behavior associated with leptospirosis. Thus, a behavioral change campaign should be promoted to encourage people awareness of the dangers of such behavior.

Cybersex in portuguese chatrooms: A study of sexual behaviors related to online sex

The present article is about a particular form of sexual activity on the Internet: cybersex in chatrooms-in Portuguese by Portuguese people. This study aims to identify the reasons for engaging in cybersex on chats and the behavioral domains that characterize this activity. To carry out the study, we developed a self-report questionnaire that we made available on a website. The sample was collected online (n = 400) through the Portuguese Internet Relay Chat. Factor analyses revealed seven domain structures: (a) social skills, (b) preference for cybersex, (c) filter for a later date, (d) sex by phone, (e) fantasies, (f) using masks, and (g) impact on real relationships. We found a huge variety of sexual attitudes and behaviors connected to cybersex in chatrooms and the existence of two major trends: (a) people that use these chats as a starting place for offline relationships (online anonymity prevents the fear of rejection and social sanctions in real life), and (b) people who want and prefer online sex without any interest in further real contacts.

Regional Disparities in Sedentary Behaviors and Meal Frequency in Iranian Adolescents: The CASPIAN-III Study

Background: The prevalence of obesity is increasing among Iranian youngsters like other developing countries. Objectives: This study was conducted to assess regional disparities in sedentary behaviors and meal frequency in Iranian adolescents. Patients and Methods: In this national survey, 5682 students aged 10 - 18 years from urban and rural districts of 27 provinces of Iran were selected via stratified multi-stage sampling method. The country was classified into four sub-national regions, based on criteria of the combination of geography and socioeconomic status (SES). Mean of meal frequency and physical activity levels as well as prevalence of omitting meals and sedentary behavior were compared across regions with different SES after stratifying with sex and age group. Results: Meal frequency in lower socio-economic regions was significantly higher than two other regions in 10 - 13 and 10 - 18 years old groups (P trend < 0.001). However, the mean of working hours with computer was linearly increased with increasing the SES in studied regions (P trend < 0.001), whereas the corresponding figure was not significant for the mean of watching TV (P trend > 0.05). Frequency of adolescents omitting their meals was higher in higher SES regions especially in West Iran (P < 0.001) in 10 - 13 years old age group. Having personal computer and working with it more than two hours per day mainly was observed in central Iran which ranked as the highest SES group. Conclusions: Efforts to ensure Iranian youth meet healthy food habits and screen time guidelines include limiting access to screen technologies and encouraging parents to monitor their own screen time is required.

Changes in skin protection behaviors, attitudes, and sunburn: In a population with the highest incidence of skin cancer in the world

This study describes changes in skin protection attitudes and outdoor behaviors of adults in Queensland, Australia, using two cross-sectional telephone surveys conducted in 1988/89 (N = 1699) and 1991/92 (N = 2317). After adjustment for potential confounders, there were significant improvements in some skin protection attitudes, time spent outside, hat wearing, sunscreen use, overall skin protection (p < 0.01) and shade use (p < 0.05) between 11:00 AM and 3:00 PM on the previous Sunday. The degree of attitudinal and behavioral change varied with age, gender, region, and reported skin type. However, recent sunburn experience remained unchanged. A similar study in Victoria, Australia, observed changes in skin protection attitudes, behaviors, and recent sunburn. We speculate on possible explanations for the lack of improvement in recent sunburn experience despite the improvement in skin protection attitudes, and behaviors, and suggest that part of the explanation may be environmental differences. This has implications for generalizability of such studies outside the geographical region in which they were conducted. Article in Cancer Detection and Prevention 20(6):566-75 · January 1996

Gender Differences in the Influence of Protective Factors, Risk Factors, and Health Risk Behaviors on HIV Risk Behaviors Among Youth in South Florida

Adolescents engage in a range of risk behaviors during their transition from childhood to adulthood. Identifying and understanding interpersonal and socio-environmental factors that may influence risk-taking is imperative in order to meet the Healthy People 2020 goals of reducing the incidence of unintended pregnancies, HIV, and other sexually transmitted infections among youth. The purpose of this study was to investigate gender differences in the predictors of HIV risk behaviors among South Florida youth. More specifically, this study examined how protective factors, risk factors, and health risk behaviors, derived from a guiding framework using the Theory of Problem Behavior and Theory of Gender and Power, were associated with HIV risk behavior. A secondary analysis of 2009 Youth Risk Behavior Survey data sets from Miami-Dade, Broward, and Palm Beach school districts tested hypotheses for factors associated with HIV risk behaviors. The sample consisted of 5,869 high school students (mean age 16.1 years), with 69% identifying as Black or Hispanic. Logistic regression analyses revealed gender differences in the predictors of HIV risk behavior. An increase in the health risk behaviors was related to an increase in the odds that a student would engage in HIV risk behavior. An increase in risk factors was also found to significantly predict an increase in the odds of HIV risk behavior, but only in females. Also, the probability of participation in HIV risk behavior increased with grade level. Post-hoc analyses identified recent sexual activity (past 3 months) as the strongest predictor of condom nonuse and having four or more sexual partners for both genders. The strongest predictors of having sex under the influence of drugs/alcohol were alcohol use in both genders, marijuana use in females, and physical fighting in males. Gender differences in the predictors of unprotected sex, multiple sexual partners, and having sex under the influence were also found. Additional studies are warranted to understand the gender differences in predictors of HIV risk behavior among youth in order to better inform prevention programming and policy, as well as meet the national Healthy People 2020 goals.

Learning data-driven models of non-verbal behaviors for building rapport using an intelligent virtual agent

There is a growing societal need to address the increasing prevalence of behavioral health issues, such as obesity, alcohol or drug use, and general lack of treatment adherence for a variety of health problems. The statistics, worldwide and in the USA, are daunting. Excessive alcohol use is the third leading preventable cause of death in the United States (with 79,000 deaths annually), and is responsible for a wide range of health and social problems. On the positive side though, these behavioral health issues (and associated possible diseases) can often be prevented with relatively simple lifestyle changes, such as losing weight with a diet and/or physical exercise, or learning how to reduce alcohol consumption. Medicine has therefore started to move toward finding ways of preventively promoting wellness, rather than solely treating already established illness.^ Evidence-based patient-centered Brief Motivational Interviewing (BMI) interventions have been found particularly effective in helping people find intrinsic motivation to change problem behaviors after short counseling sessions, and to maintain healthy lifestyles over the long-term. Lack of locally available personnel well-trained in BMI, however, often limits access to successful interventions for people in need. To fill this accessibility gap, Computer-Based Interventions (CBIs) have started to emerge. Success of the CBIs, however, critically relies on insuring engagement and retention of CBI users so that they remain motivated to use these systems and come back to use them over the long term as necessary.^ Because of their text-only interfaces, current CBIs can therefore only express limited empathy and rapport, which are the most important factors of health interventions. Fortunately, in the last decade, computer science research has progressed in the design of simulated human characters with anthropomorphic communicative abilities. Virtual characters interact using humans’ innate communication modalities, such as facial expressions, body language, speech, and natural language understanding. By advancing research in Artificial Intelligence (AI), we can improve the ability of artificial agents to help us solve CBI problems.^ To facilitate successful communication and social interaction between artificial agents and human partners, it is essential that aspects of human social behavior, especially empathy and rapport, be considered when designing human-computer interfaces. Hence, the goal of the present dissertation is to provide a computational model of rapport to enhance an artificial agent’s social behavior, and to provide an experimental tool for the psychological theories shaping the model. Parts of this thesis were already published in [LYL+12, AYL12, AL13, ALYR13, LAYR13, YALR13, ALY14].^

Investigation of Escape and Negative Student Behaviors Related to Florida State High Stakes Test Preparation in Miami-Dade County Public High Schools, having been approved in respect to style and intellectual content, is referred to you for judgment

The purpose of this study was to determine whether there was a relationship between pressure to perform on state mandated, high-stakes tests and the rate of student escape behavior defined as the number of school suspensions and absences. The state assigned grade of a school was used as a surrogate measure of pressure with the assumption that pressure increased as the school grade decreased. Student attendance and suspension data were gathered from all 33 of the regular public high schools in Miami-Dade County Public Schools. The research questions were: Is the number of suspensions highest in the third quarter, when most FCAT preparation takes place for each of the 3 school years 2007-08 through 2009-10? How accurately does the high school’s grade predict the number of suspensions and number of absences during each of the 4 school years 2005-06 through 2008-09? The research questions were answered using repeated measures analysis of variance for research question #1 and non-linear multiple regression for research question #2. No significant difference could be found between the numbers of suspensions in each of the grading periods nor was there a relationship between the number of suspensions and school grade. A statistically significant relationship was found between student attendance and school grade. When plotted, this relationship was found to be quadratic in nature and formed a loose inverted U for each of the four years during which data were collected. This indicated that students in very high and very low performing schools had low levels of absences while those in the midlevel of the distribution of school performance (C schools) had the greatest rates of absence. Identifying a relationship between the pressures associated with high stakes testing and student escape behavior suggests that it might be useful for building administrators to reevaluate test preparation activities and procedures being used in their building and to include anxiety reducing strategies. As a relationship was found, it sets the foundation for future studies to identify whether testing related activities are impacting some students emotionally and are causing unintended consequences of testing mandates.
