Mental health correlates of healthy lifestyle attitudes, beliefs, choices, and behaviors in overweight adolescents.

INTRODUCTION: A tripling in the number of overweight adolescents has occurred during the past two decades, with type 2 diabetes reaching epidemic proportions. Although obesity has been identified as a correlate of depression and low self-esteem in adolescents, the relationships among key cognitive/mental health variables and healthy attitudes, beliefs, choices, and behaviors in overweight teens have yet to be explored. Therefore, the aim of this study was to describe these relationships so that an effective intervention program to promote and sustain healthy lifestyle behaviors could be implemented. METHODS: A descriptive correlational study was conducted with 23 overweight teens. Key variables measured included depressive symptoms, state and trait anxiety, self-esteem, beliefs/confidence about engaging in a healthy lifestyle, perceived difficulty in leading a healthy lifestyle, and healthy attitudes, choices, and behaviors. FINDINGS: Teens with higher state and trait anxiety as well as depressive symptoms had less healthy lifestyle beliefs, and teens with higher self-esteem had stronger beliefs about their ability to engage in a healthy lifestyle. Stronger beliefs about the ability to engage in healthy lifestyles were related to healthier living attitudes and healthier lifestyle choices. Teens who perceived healthy lifestyles as more difficult had less healthy attitudes and reported less healthier choices and behaviors. DISCUSSION: Including a strong cognitive behavioral skills building component into clinical interventions with overweight teens may be key in boosting their beliefs/confidence about being able to engage in healthy behaviors and lessening their perceived difficulty in performing them, which should result in healthier choices and lifestyle behaviors.

PASSCLAIM--mental state and performance.

BACKGROUND: The intake of food and drink can influence brain functions, which in turn may have effects on mental state and performance. Therefore, in principle claims to improve mood or specific aspects of cognitive performance by the consumption of functional foods are possible and indeed are currently found on the market. AIM: The paper reviews existing methodologies, which may be used to substantiate and validate such claims of desirable effects of foods on mental state and performance. RESULTS: Mood, arousal, activation, vigilance, attention, sleep, motivation, effort, perception, memory and intelligence have been identified as relevant aspects of mental state and performance. The basic scientific concepts within this field as well as the methodologies to measure these concepts have been reviewed and described. CONCLUSIONS: From this review it is concluded that, in principle, the phenomena in these fields are no different to those in other fields of life science. The scientific methods and protocols described in this report can positively demonstrate the effects of foods on mental state and performance in a scientifically valid way. A claim on mental state and performance like other claims must be based on scientific evidence. This report confirms that methodologies do exist to generate sound scientific evidence in this area. Therefore, claims on the enhancement of specific mental functions can and should be substantiated and validated using the methodologies described in this review.

The uniqueness of human learning.

It is proposed that humans are capable of a unique type of learning. All other animals are limited to contiguous learning (not more than 60 seconds separating the two events). Only humans are capable of "separated" or scientific learning (learning a connection between two or more events separated by more than 60 seconds). Science itself is a generalized type of non-contiguous learning. It is also proposed that humans' capacity for separated learning is dependent upon the unique ability to hypothesize (to propose a connection or relationship between two or more events separated by time). As a result of separated learning, humans are the only animals capable of "separated foresight" (anticipating which events are likely to occur more than one minute into the future).

[Behavioral dental science. Part VIII. The dentist's rating and adolescents' perceptions of oral health].

The purpose of this study was twofold. The first objective was to measure the periodontal status and perceptions of oral health in adolescents. The second objective was to determine the effects that a program of dental health education would have on their periodontal status and perceptions of oral health. The dental health education with a 90-minute lecture had been given to eleventh-grade students (352) in the previous year. The dental health education program was not carried out in tenth-grade students (442) yet. The oral examination was performed by a dentist for both grades. The examination time was about ten seconds per person. The students' periodontal status was scored as "excellent (+2)," "good (+1)," "questionable (0)," "poor (-1)," or "very poor (-2)" according to the criteria of an Oral Rating Index (ORI) System proposed by the present authors. The level of students' perceptions was assessed by the cognition score of our dental health test (10 items concerning dental attitudes and behavior). Main results were as follows: 1. Only 6% of the 10-th grade students were judged as having "excellent (+2)" oral health. Thirty-six percent were "very poor (-2)" or "poor (-1)" periodontal status. 2. The mean cognition score and the mean ORI score of the 11-th grade students were significantly greater for each sex group than those of the 10-th grade students. 3. The cognition score showed a clear relationship to the ORI score in each grade and in all. The behavioral component of the cognition score was more closely related to the ORI score. These findings suggest that the dental health education contributes to the improvement of periodontal status as well as that of perceptions. Furthermore, the ORI may be utilized for a screening system to evaluate adolescents' periodontal status quickly and effectively.

Measuring facial expressions by computer image analysis.

Facial expressions provide an important behavioral measure for the study of emotion, cognitive processes, and social interaction. The Facial Action Coding System (Ekman & Friesen, 1978) is an objective method for quantifying facial movement in terms of component actions. We applied computer image analysis to the problem of automatically detecting facial actions in sequences of images. Three approaches were compared: holistic spatial analysis, explicit measurement of features such as wrinkles, and estimation of motion flow fields. The three methods were combined in a hybrid system that classified six upper facial actions with 91% accuracy. The hybrid system outperformed human nonexperts on this task and performed as well as highly trained experts. An automated system would make facial expression measurement more widely accessible as a research tool in behavioral science and investigations of the neural substrates of emotion.

Evaluation of the noncognitive professional traits of medical students.

BACKGROUND: Professional attributes such as honesty, integrity, and reliability are critical to success in medical school and postgraduate practice, yet such noncognitive attributes have traditionally been poorly evaluated. METHOD: A program of evaluating students' noncognitive professional attributes at the University of New Mexico School of Medicine was reviewed over a four-year period, from 1987-88 through 1990-91, involving the approximately 525 students enrolled at the school at that time. The evaluation program enabled faculty and staff to quantify their impressions of problem students in a uniform manner, by using an evaluation form that listed and described seven basic professional traits. RESULTS: Over the study years the program identified ten students with difficulties in the basic science and clinical years regarding their character and professionalism. For these ten students, interventions ranged from nothing being done, in one case, to such significant remediations as recommendations of extensive counseling and a leave of absence. One student was dismissed, on the basis of poor academic performance, and the other nine have graduated. In some cases, students noticeably improved their professional behaviors, but whether their behaviors changed as a result of the interventions can't be determined. CONCLUSION: By identifying and tracking students with difficulties, the program offers the opportunity for intervention and, ideally, remediation. This program can complement systems that evaluate academic performance. Such a program can help an institution assure not only the cognitive competence of its graduates, but the competence of their professional behaviors as well.

Psychiatric education in an era of rapidly occurring scientific advances.

Scientific advances in the fields of molecular biology, neurobiology, pharmacology, epidemiology, genetics, neuroimaging, and cognitive neuroscience are influencing psychiatric diagnosis and treatment, and this influence will grow substantially in the future. The current shortage of psychiatrists will increase over the next several decades, resulting in the need to train primary care physicians in basic psychiatric care and the use of non-physician mental health professionals to administer time-intensive, formal psychotherapies. The juxtaposition of these two trends-an increasing scientific influence on the clinical practice of psychiatry and fewer psychiatrists to deliver that treatment-is cause for changes in the approach to psychiatric education. In addressing these issues, the authors suggest that (1) psychiatry should be more integrated into undergraduate medical education in both basic science and clinical curricula, (2) residents in primary care disciplines should have more direct exposure to psychiatric training, (3) joint instructional experiences involving psychiatry and primary care residents should be encouraged, (4) psychiatry residency programs should maintain flexibility in order to incorporate rapid advances in diagnostic procedures and treatments into residency training, (5) research experience should be integrated into psychiatry residency programs, and (6) departments of psychiatry must develop the leadership and expertise necessary to implement the incorporation of rapidly advancing scientific discoveries into the psychiatric curriculum.

From autopoiesis to neurophenomenology: Francisco Varela's exploration of the biophysics of being.

This paper reviews in detail Francisco Varela's work on subjectivity and consciousness in the biological sciences. His original approach to this "hard problem" presents a subjectivity that is radically intertwined with its biological and physical roots. It must be understood within the framework of his theory of a concrete, embodied dynamics, grounded in his general theory of autonomous systems. Through concepts and paradigms such as biological autonomy, embodiment and neurophenomenology, the article explores the multiple levels of circular causality assumed by Varela to play a fundamental role in the emergence of human experience. The concept of biological autonomy provides the necessary and sufficient conditions for characterizing biological life and identity as an emergent and circular self-producing process. Embodiment provides a systemic and dynamical framework for understanding how a cognitive self--a mind--can arise in an organism in the midst of its operational cycles of internal regulation and ongoing sensorimotor coupling. Global subjective properties can emerge at different levels from the interactions of components and can reciprocally constrain local processes through an ongoing, recursive morphodynamics. Neurophenomenology is a supplementary step in the study of consciousness. Through a rigorous method, it advocates the careful examination of experience with first-person methodologies. It attempts to create heuristic mutual constraints between biophysical data and data produced by accounts of subjective experience. The aim is to explicitly ground the active and disciplined insight the subject has about his/her experience in a biophysical emergent process. Finally, we discuss Varela's essential contribution to our understanding of the generation of consciousness in the framework of what we call his "biophysics of being."

Children with disabilities: a longitudinal study of child development and parent well-being.

This Monograph presents the results of the Early Intervention Collaborative Study, a longitudinal investigation of the cognitive and adaptive behavior development of children with developmental disabilities and the adaptation of their parents, extending from infancy through middle childhood. The study was designed to generate and test conceptual models of child and family development and contribute to the knowledge base that informs social policy and practice. The sample for the investigation reported here consists of 183 children with Down syndrome, motor impairment, developmental delay and their families who were recruited at the time of their enrollment in an early intervention program in Massachusetts or New Hampshire. Data were collected at five time points between entry to early intervention and the child's 10th birthday. Home visits were conducted at each time point and included child assessments, maternal interview, and questionnaires completed independently by both parents. Trajectories in children's development and parental well-being were analyzed using hierarchical linear modeling. Predictor variables were measured at age 3 years when children were exiting early intervention programs. Children's type of disability predicted trajectories of development in cognition, social skills, and daily living skills. Children's type of disability also predicted changes in maternal (but not paternal) child-related and parent-related stress. Beyond type of disability, child self-regulatory processes (notably behavior problems and mastery motivation) and one aspect of the family climate (notably mother-child interaction) were key predictors of change in both child outcomes and parent well-being. A different aspect of the family climate--family relations--also predicted change in child social skills. Parent assets, measured as social support and problem-focused coping, predicted change in maternal and paternal parent-related stress respectively. The implications of these findings for both the science of child development and the policies and practices of developmental intervention are discussed.

Therapeutic jurisprudence in the courts.

Therapeutic jurisprudence is an emerging field of law and social science inquiry that explores the role of the law in fostering therapeutic or antitherapeutic outcomes. This article considers the relationship between therapeutic jurisprudence and court performance goals, examines applications of therapeutic jurisprudence in court settings, discusses the steps involved in incorporating therapeutic jurisprudence principles into the work of courts, outlines the pros and cons associated with practicing therapeutic jurisprudence primarily in specialized courts, and offers suggestions for fostering continued experimentation by courts.

Language-specific effects on number computation in toddlers.

A fundamental question in developmental science is how brains with and without language compute numbers. Measuring young children's verbal reactions in France (Paris) and in England (Oxford), here we show that, although there is a general arithmetic ability for small numbers that is shared by monkeys and preverbal infants, the development of such initial knowledge in humans follows specific performance patterns, depending on what language the children speak.

Neural networks for longitudinal studies in Alzheimer's disease.

OBJECTIVE: Alzheimer's disease affects a growing population of elderly people today. The predictions about the course of the disease is a key component of health care decision making for patients with Alzheimer's. The physician's prognosis and predicted trajectory of cognitive decline often form the basis of treatment and health care decisions taken by patients and their families. These predictions are difficult to make because of the high variability and non-linearity exhibited by individual patterns of cognitive decline. This paper presents a new method of predicting the course of a disease using longitudinal data collected through multiple clinic visits. Longitudinal databases are similar to temporal databases, with some important differences--data is collected at irregular time intervals that are patient specific and also a varying number of observations are made for each patient, depending upon the number of times the patient visited the clinic. We propose a new type of neural network called the mixed effects neural network (MENN) model that can incorporate this type of longitudinal information. MATERIAL AND METHODS: We have used longitudinal data on 704 subjects enrolled at the Layton aging and research center (LAARC) at Oregon Health and Science University. A back-propagation algorithm, modified for longitudinal data is used to obtain the weight parameters of the MENN. The modified back-propagation algorithm is further embedded in an iterative procedure that estimates the noise variance and the parameters that capture the longitudinal (temporal) correlation structure. RESULTS: We have compared the performance of the MENN with linear mixed effects models and standard neural networks (NN). MENN show better performance (misclassification rate = 0.13 and relative MSE = 0.35) as compared to standard NN (misclassification rate = 0.34 and relative MSE = 2.74) and linear mixed effects models (misclassification rate = 0.14 and relative MSE = 0.4). CONCLUSION: The results show that this method can be a useful tool for predicting non-linear disease trajectories and uncovering significant prognostic factors in longitudinal databases.

Cognitive orientation and genital infections in young women.

The purpose was to explore the psychological determinants of common genital infections in young women. The study was done in the framework of the cognitive orientation theory which assumes that cognition guides behavior and provides predictions of behaviors and psychophysiological phenomena. We expected that beliefs of four types (about self, norms, goals, and general) would predict the occurrence and/or frequency of 17 gynecological symptoms (e.g., itching, swelling, different vaginal discharges, abscesses). The subjects were 195 female volunteers, undergraduates, about 23 years old, without gross gynecological disorders, mostly (87.7%) unmarried, mostly (83.6%) having had intercourse. They were administered anonymously questionnaires about demographic variables, frequency and treatment of gynecological symptoms and 3 urological ones (for control), and about cognitive orientation that referred to pretested themes (e.g., assertiveness, hypochondriasis). Stepwise discriminant and regression analyses showed that the belief types enabled predicting the occurrence and frequency of all symptoms, with a mean 34.5% improvement over the 50% chance level, accounting for 45.7-67.2% of the variance. Also the urological symptoms were predicted although at a lower level. Discussion focuses on the specificity of cognitive-motivational determinants and their role in producing conditions favoring physical pathology.

[The analysis of physicians' work: announcing the end of attempts at in vitro fertilization].

The purpose of this empirical study is to analyze modalities of announcing the end of attempts at in vitro ferti-lization to women who, for various reasons, were not able to have a child after several trials. What are the problems physicians face when, in the course of their work, they make these announcements? How do they give (or not give) support to these women who have placed so much hope in this technique? These are some of the questions that led the authors to conduct this empirical study within the framework of a clinical and qualitative approach to work psychology. Within this framework, work is conceptualised as a complex activity that involves the subject, both bodily and through his various modes of socialisation. The field of clinical and quali-tative approach to work psychology situations focuses on different ways of expressing distress related to contradictory work demands, as the activity is being performed; it also focuses on those creative processes used by the subject to cope with those internal and external conflicts that hinder task performance. A review of the literature and preliminary observations led us to postulate that the problems physicians are faced with when they announce the end of attempts at in vitro fertilisation (IVF) are linked to several conflicts between work values (that are specific to the medical world) and the recognition of work failure: termination of attempts at IVF. The popu-lation that participated in this research project belongs to a network of private practitioners who work with the in-house team of a Parisian clinic. But the group is not uniform and some physicians perform IVFs more frequently than others. Our qualitative study involved 10 semi-directive interviews of approximately 1 1/2 hours each, which were recorded and transcribed. Initial instructions focused on a concrete description of situations of abandonment of attempts at IVF, in terms of their preparation, development, and the way they are experienced . Interviews therefore centred on specific and limited practitioner activity. Each transcription was submitted to a Qualitative Analysis of Discourse, followed by a comparative analysis of the 10 transcriptions. We propose an original method of Qualitative Analysis of Discourse, to be applied to semi-structured clinical interviews. This method seeks to analyse the structure of the resulting egocentric monologue in research si-tuations of semi-directive interviewing. The method of Quali-tative Analysis of Discourse involves three steps, but only the first two were applied in this work: a) identification of sequences of discourse; b) analysis of relationships between statements; c) stylistic analysis of figures of speech. Our first set of analyses showed that seve-ral markers increase in physicians' discourse when they describe difficult and/or conflict-laden consultation situations: logical connectors, impersonal pronouns, reported discourse, anti-cipations regarding the interviewer's judgement. The logical balance of the discourse therefore appears threatened when pro-blems inherent in the work demands involved in ending IVF attempts are mentioned. As a whole, these markers underscore the importance of the implicit dimension of discourse (inferences, presuppositions, hints, allusions, etc.), thus reflecting complex speech that attempts to negotiate between subjective positions and shared cultural values. A comparative analysis of the markers identified in the 10 interviews revealed four areas, each involving nervous tension poles, that are suggestive of cognitive-emotional dissonance in the task to be performed. Some factors increase professional distress while others temper it. They act upon the work situation itself on the one hand, and on the working relationship between physician and patient on the other. 1. Areas of tension relating to the task to be performed. The first area contrasts individual with collective decision-making. The independent status which characterises private medical practice increases self-esteem in cases of success but weakens it when IVF attempts fail. In addition, it goes against collective involvement in the work situation, yet such involvement may act as a strong moderating factor for the experience of distress. The second area contrasts work that is well done with recognition by peers. Indeed, in the hierarchy of medical values, recognition by peers that work has been well performed is anchored in successful healing (in the broad sense of the term), whereas in situations of abandonment of IVF attempts, ending the attempt is considered by everyone to be a failure, even if it has been well conducted . The third area opposes objective medical practice to a necessarily subjective medical involvement. The scientific and ideal values which characterise medicine reflect its objective and scientific orientation, but IVF situations are a reminder that medicine is not an exact science and that it can make mistakes. There are numerous special individual cases which reduce certainty that a decision to terminate IVF is well-founded. The fourth area distinguishes between work that is considered to be well done and work considered to be well conducted . Personal estimation of work that is well done is based on the impression that the maximum feasible has been done . But in IVF situations, constant uncertainty leads to professional over-involvement (examinations, verifications, changes of protocols). Work that is poorly done is work that does not cure or that brings no relief. As a result, work that consists in ending IVF attempts, even if it is well conducted , remains a subjective failure for everyone since it does not bring a cure (pregnancy). 2. Areas of tension in the physician-patient relationship. The first area contrasts women's irrational desire with possible support from their husbands, when the time has come to announce the end of the attempts. But this voice/presence of husbands is consi-dered desirable and important only when attempts have failed, so that husbands are not encouraged to participate in the protocols except to help restrain their wives' over reactions . The second area opposes respect for the patient role with demands made by women. Lack of respect for the patient role, by making demands or by refusing to follow advice, particularly when IVF attempts are abandoned, crystallises all the resentment experienced by physicians in difficult work situations. Two cognitive-emotional worlds, more or less tuned to one another over the course of the IVF, start to clash and lose all mutual understanding: the medical world and the patient's subjective world. The third area results from the second one. It contrasts a listening physician with a powerful one. Physicians are very concerned that their relationship with their patients be one of partnership. But this (idealised) equilibrium is abruptly disrupted by the end of the attempts, inasmuch as it is the physician who has the power to stop these attempts and who decides to do so. The unveiling of this reality of a power relationship becomes a source of suffering and contradicts expressed surface values. The fourth area contrasts an attitude of ongoing patient support based on a belief in success with an attitude of patient support based on the prediction of a possible failure. Indeed, for a patient to be supported in a way physicians would consider right and adequate , the abandonment of IVF attempts should be anticipated in advance so that the physician can prepare both himself and the patients for the high risk of failure. But physicians insist on the fact that medical work can only succeed if they believe in it . As a result, the more energy the physician puts into launching the initial phase of IVF, the greater the feeling of self-accomplishment during the first phase of IVF; but conversely, the weaker the efficacy of the process of seeing the patient through the end of the attempts, the stronger the fee-ling of subjective distress at work will be. Overall, it is a para-doxical work situation for physicians to have to anticipate the interruption of IVF attempts and to have to prepare for seeing the patient through this abandonment. This situation creates conflicts of representations and values within their very practice and generates distress at work. It is worth noting that some moderating factors could alleviate their sense of suffering and contribute to improving their work experience: a) the deve-lopment of a protocol for seeing patients through the end of IVF attempts, which would make abandonment part of a job well done for physicians; b) regular participation by the spouse in these protocols; c) making all decisions to end IVF attempts a collective process, in order to avoid placing exclusive responsibility on the treating physician. The limitations of this study are inherent both in the qualitative nature of the data that involve a small number of physicians, and in the specificity of this population that works within a poorly structured network. On the other hand, our method of Qualitative Analysis of Discourse can be applied to all types of discourse obtained in research situations, provided the discourse is produced through semi-directive or non-directive interviews.

[Fifty years of nutrition counseling. Remarks and perspectives].

Fifty years of nutrition information and education did not reach their goals. Nutrition-dependent diseases, obesity, and misinformation are still increasing. Cognitive information about nutrition does not induce changes in primary emotion-controlled eating habits. Better knowledge of nutrition on the part of consumers mainly activates their bad conscience when they rate their own eating habits. Future prevention campaigns, which clearly address consumer needs using social marketing principles, will be better able to change eating behavior.

Is conscious perception gradual or dichotomous? A comparison of report methodologies during a visual task.

In a recent article, [Sergent, C. & Dehaene, S. (2004). Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink, Psychological Science, 15(11), 720-729] claim to give experimental support to the thesis that there is a clear transition between conscious and unconscious perception. This idea is opposed to theoretical arguments that we should think of conscious perception as a continuum of clarity, with e.g., fringe conscious states [Mangan, B. (2001). Sensation's ghost-the non-sensory "fringe" of consciousness, Psyche, 7, 18]. In the experimental study described in this article, we find support for this opposite notion that we should have a parsimonious account of conscious perception. Our reported finding relates to the hypothesis that there is more than one perceptual threshold [Merikle, P.M., Smilek, D. & Eastwood, J.D. (2001). Perception without awareness: perspectives from cognitive psychology, Cognition, 79, 115-134], but goes further to argue that there are different "levels" of conscious perception.

A description of the social-ecological framework used in the trial of activity for adolescent girls (TAAG).

Social-ecological (SE) models are becoming more widely used in health behavior research. Applying SE models to the design of interventions is challenging because models must be tailor-made for each behavior and population, other theories need to be integrated into multi-level frameworks, and empirical research to guide model development is limited. The purpose of the present paper is to describe a SE framework that guided the intervention and measurement plans for a specific study. The trial of activity for adolescent girls (TAAG) is a multi-center study of interventions to reduce the decline of physical activity in adolescent girls. The TAAG framework incorporates operant learning theory, social cognitive theory, organizational change theory and the diffusion of innovation model in a multi-level model. The explicit and practical model developed for TAAG has already benefited the study and may have elements that can generalize to other health promotion studies.

Theoretical description of teaching-learning processes: a multidisciplinary approach.

A multidisciplinary approach based on concepts from sociology, educational psychology, statistical physics, and computational science is developed for the theoretical description of teaching-learning processes that take place in the classroom. The emerging model is consistent with well-established empirical results, such as the higher achievements reached working in collaborative groups and the influence of the structure of the group on the achievements of the individuals. Furthermore, another social learning process that takes place in massive interactions among individuals via the Internet is also investigated.
