The Effects of Implicit Theories on Body Weight Information Avoidance.

Regular self-weighing is associated with more effective weight control, yet many individuals avoid weight-related information. Implicit theories about weight, or perceptions of how malleable weight is, predict more effortful weight management and may also influence weight-related information avoidance. Participants (N = 209) were randomly assigned to read an article stressing an incremental theory of weight (i.e., weight is malleable), an article stressing an entity theory (i.e., weight is fixed), or to a control condition. We then examined their self-reported preference to avoid their body composition (i.e., body fat, weight, and muscle composition), their willingness to have their body composition measured during the lab visit, and their eating and exercise intentions. There were no notable differences across conditions, but higher self-reported incremental beliefs predicted less self-reported avoidance of body composition. The findings suggest that implicit theories may influence weight-related information avoidance, but a brief manipulation is not powerful enough to create meaningful change.

Using artificial intelligence to identify the top 50 independent predictors of subjective well-being in a multinational sample of 37,991 older European & Israeli adults.

Subjective well-being (SWB) is widely recognized as an important health outcome, but its complexity, myriad predictors, and analytic requirements pose significant challenges to identifying the relative order and impact of SWB determinants. This study involved a representative sample of 37,991 older adults from 17 European countries and Israel. An aggregate index of SWB was developed and compared across countries, and machine-learning algorithms were used to rank-order the strongest 50 (of an initial 94) SWB predictors from 15 categories. General Additive Modeling (GAM) and low-degree polynomials (i.e., splines) were used to determine the independent effect sizes and significance levels for each of these top-50 SWB predictors. Of the 18 countries included in this study, Denmark had the highest mean SWB, while Greece had the lowest. The two top-ranked SWB predictors (loneliness, social activity satisfaction) were social factors, which also had the highest overall group ranking, followed by physical health, demographics, financial status and personality. Self-reported health was the strongest health-related predictor, neuroticism was the strongest personality predictor, and women reported higher SWB than men. SWB decreased with age, and increased with income up to 350,000 euros/year, after which it declined. Social factors were of primary importance for subjective well-being in this research, while childhood experiences and healthcare status exerted the smallest effects. The vast majority of the top 50 SWB predictors were statistically significant, with the notable exceptions of body mass index and most health behaviors, which may impact SWB indirectly through their effects on physical health. Future multivariate modeling is recommended to clarify the mechanisms for these and other observed relationships.

Multilevel mobile health approach to improve cardiovascular health in resource-limited communities with Step It Up: a randomised controlled trial protocol targeting physical activity.

INTRODUCTION: Although physical activity (PA) reduces cardiovascular disease (CVD) risk, physical inactivity remains a pressing public health concern, especially among African American (AA) women in the USA. PA interventions focused on AA women living in resource-limited communities with scarce PA infrastructure are needed. Mobile health (mHealth) technology can increase access to PA interventions. We describe the development of a clinical protocol for a multilevel, community-based, mHealth PA intervention for AA women. METHODS AND ANALYSIS: An mHealth intervention targeting AA women living in resource-limited Washington, DC communities was developed based on the socioecological framework for PA. Over 6 months, we will use a Sequential Multi-Assignment, Randomized Trial approach to compare the effects on PA of location-based remote messaging (named 'tailored-to-place') to standard remote messaging in an mHealth intervention. Participants will be randomised to a remote messaging intervention for 3 months, at which point the intervention strategy will adapt based on individuals' PA levels. Those who do not meet the PA goal will be rerandomised to more intensive treatment. Participants will be followed for another 3 months to determine the contribution of each mHealth intervention to PA level. This protocol will use novel statistical approaches to account for the adaptive strategy. Finally, effects of PA changes on CVD risk biomarkers will be characterised. ETHICS AND DISSEMINATION: This protocol has been developed in partnership with a Washington, DC-area community advisory board to ensure feasibility and acceptability to community members. The National Institutes of Health Intramural IRB approved this research and the National Heart, Lung, and Blood Institute provided funding. Once published, results of this work will be disseminated to community members through presentations at community advisory board meetings and our quarterly newsletter. TRIAL REGISTRATION NUMBER: NCT03288207.

Psychological functioning, brain morphology, and functional neuroimaging in Klinefelter syndrome.

Klinefelter syndrome (KS; 47,XXY) impacts neurodevelopment and is associated with an increased risk of cognitive, psychological and social impairments, although significant heterogeneity in the neurodevelopmental profile is seen. KS is characterized by a specific cognitive profile with predominantly verbal deficits, preserved function in non-verbal and visuo-spatial domains, executive dysfunction and social impairments, and by an increased vulnerability toward psychiatric disorders. The neurobiological underpinnings of the observed neuropsychological profile have not been established. A distinct pattern of both global and regional brain volumetric differences has been demonstrated in addition to preliminary findings of functional brain alterations related to auditory, motor, language and social processing. When present, the combination of cognitive, psychological and social challenges has the potential to negatively affect quality of life. This review intends to provide information and insight to the neuropsychological outcome and brain correlates of KS. Possible clinical intervention and future directions of research will be discussed.

Assessing Mozambicans' willingness and determinants to use pre-exposure prophylactic HIV medication.

In anticipation of the introduction of the pre-exposure prophylaxis drugs as an additional HIV prevention tool, we mapped the different positions of Mozambicans' willingness to use it. Overall, 507 adults indicated willingness to use under different conditions varying as a function of perceived susceptibility to and severity of infection, side effects, administration protocol, and cost. Three qualitatively different positions were found: Unwillingness irrespective of conditions (4%), depend on circumstances (76%), and unconditional willingness (8%). A large majority of participants were willing to use pre-exposure prophylaxis drugs, provided that the administration is not too constraining, and the adverse side effects can be minimized.

Identifying determinants of Mozambican men's willingness to use a male contraceptive pill.

Objective: Given the possibility of a male contraceptive pill in the near future, understanding men's attitudes towards this contraceptive method is crucial, especially in high-risk populations with limited access to education. This research was conducted to identify the determinants of Mozambican men's willingness to use a contraceptive pill when it is made available. Methods: A sample of 412 Mozambican men was presented with 36 vignettes comprising four within-subject factors (cost of pills, pill efficacy, side effects and context). Each vignette presented a scenario in which a man is asked by his partner to use the contraceptive pill, and participants indicated their own willingness to use the pill under each circumstance. Results: Cluster analysis revealed that participants took one of four different positions regarding their willingness to use a contraceptive pill: never (11%); depends on side effects alone (25%); depends on side effects and costs (11%); depends on side effects and context (46%). These positions were associated with participants' sociodemographic characteristics. Conclusion: Among the Mozambican men in this study, a minority appeared to believe that the responsibility for contraception should be shared between sexual partners. Men's willingness to use a contraceptive pill was, however, more pronounced in the case of serious medical risk to their partner. Overall, only about one-fifth of participants were either reluctant or unwilling to consider using a male contraceptive pill.

How does education lead to healthier behaviours? Testing the mediational roles of perceived control, health literacy and social support.

OBJECTIVES: Educational attainment is increasingly recognised as a unique dimension of socioeconomic status (SES) and a powerful determinant of health behaviour-and thus physical health and mortality. However, very little is known about the specific pathways through which education influences these health behaviours. DESIGN: The present study used a nationally representative US survey to test three potential psychosocial pathways (perceived control, health literacy and social support) through which education might influence intake of fruits and vegetables (FV), physical activity (PA) and sedentary behaviour (SB), controlling for other aspects of SES (income, health insurance status) and demographics (age, gender, race/ethnicity). RESULTS: Both aspects of perceived control (locus of control, cancer fatalism) mediated the impact of education on FV and PA while only locus of control mediated the impact of education on SB. Further, only one aspect of health literacy (ability to understand recommendations) mediated education's effect on any health behaviour (FV). Social support did not mediate any of the effects of education on health behaviors. CONCLUSION: Future work explicitly assessing and testing these mediational pathways is needed to better understand how education influences people's health behaviours throughout their lives.

Anxiety and depression in Klinefelter syndrome: The impact of personality and social engagement.

Klinefelter syndrome (KS) (47, XXY) is the most common sex chromosome disorder, with a prevalence of 1 in every 660 newborn males. Despite the profound adverse effects of anxiety and depression, and their greater prevalence in KS populations, no research has been conducted to date to identify the determinants of anxiety and depression among patients with KS. We examined the relationships between personality traits, social engagement, and anxiety and depression symptoms among KS patients (n = 69) and a group of male controls (n = 69) matched for age and years of education. KS patients experienced more anxiety and depression symptoms than control participants. Neuroticism was the strongest and most consistent mediator between KS and both anxiety and depression symptoms. This research suggests that neuroticism may play a central role in attention switching, anxiety and depression among patients with Klinefelter syndrome. The central role of neuroticism suggests that it may be used to help identify and treat KS patients at particularly high-risk for attention-switching deficits, anxiety and depression.

Quality of life in men with Klinefelter syndrome: the impact of genotype, health, socioeconomics, and sexual function.

PurposeKlinefelter syndrome (KS) is associated with lower socioeconomic status and greater morbidity. However, relatively little is known about the quality of life for men with KS, or how KS and other factors combine to determine it.MethodsA total of 132 men with KS were recruited in clinics, and 313 matched controls were identified by Statistics Denmark. Demographics, socioeconomic status, health problems and behaviors, sexual function, medical follow-up, and mental and physical quality of life (MQoL and PQoL, respectively) were assessed for all participants through surveys.ResultsMen with KS reported significantly lower education attainment levels, income, physical activity, and both PQoL and MQoL, as well as more illness, medication, and sexual dysfunction. KS status was associated directly with lower PQoL, as well as indirectly through reduced income, physical activity, and sexual function, and increased body mass index. KS status and younger age were associated directly with lower MQoL, as well as indirectly through reduced income, physical activity, and partner status (for KS status), or through partner status (for age).ConclusionKS status is associated with lower PQoL and MQoL through both direct and indirect paths. These results suggest the need for more comprehensive research and clinical approaches to addressing quality of life for men with KS.

The Impact of E-diaries and Accelerometers on Young Adults' Perceived and Objectively Assessed Physical Activity.

OBJECTIVE: E-diaries and accelerometers promise more objective, real-time measurements of health behavior. However, social-psychological theory suggests that using electronic behavioral monitoring may influence rather than just record physical activity (PA), especially when a device is novel. DESIGN: Participants (n=146) were randomly assigned to either an accelerometer-only, e-diary-only, accelerometer+e-diary, or a no-technology control group for one week to assess how these technologies influenced PA, both perceived and actual, in young adults. METHOD: Participants reported their PA, overall and number of discrete exercise sessions (DES) at baseline and follow-up; accelerometers provided daily step counts and e-diaries captured daily reports of PA for the active week of the study. RESULTS: Average daily steps in the accelerometer-only and accelerometer+e-diary groups did not differ nor did daily reports of PA via e-diary compared to accelerometer+e-diary group, showing that neither technology affected actual PA. ANCOVAS tested group differences in perceived PA; The accelerometer-only group had increased perceived overall PA but not DES compared to no-technology control. CONCLUSIONS: Accelerometers may increase perceived overall PA, but the tested technologies did not increase DES or actual PA, suggesting that they may be viable unbiased measures of PA.

The role of genes, intelligence, personality, and social engagement in cognitive performance in Klinefelter syndrome.

INTRODUCTION: The determinants of cognitive deficits among individuals with Klinefelter syndrome (KS) are not well understood. This study was conducted to assess the impact of general intelligence, personality, and social engagement on cognitive performance among patients with KS and a group of controls matched for age and years of education. METHODS: Sixty-nine patients with KS and 69 controls were assessed in terms of IQ, NEO personality inventory, the Autism Spectrum Quotient (AQ) scale, and measures of cognitive performance reflecting working memory and executive function. RESULTS: Patients with KS performed more poorly on memory and executive-function tasks. Patients with KS also exhibited greater neuroticism and less extraversion, openness, and conscientiousness than controls. Memory deficits among patients with KS were associated with lower intelligence, while diminished executive functioning was mediated by both lower intelligence and less social engagement. CONCLUSION: Our results suggest that among patients with KS, memory deficits are principally a function of lower general intelligence, while executive-function deficits are associated with both lower intelligence and poorer social skills. This suggests a potential influence of social engagement on executive cognitive functioning (and/or vice-versa) among individuals with KS, and perhaps those with other genetic disorders. Future longitudinal research would be important to further clarify this and other issues discussed in this research.

Lay theories of smoking and young adult nonsmokers' and smokers' smoking expectations.

This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed.

Psychological resilience: the impact of affectivity and coping on state anxiety and positive emotions during and after the Washington, DC sniper killings.

This research examined the impact of affectivity and coping on state anxiety and positive emotions among young adults living in the Washington, DC metro area both during and after the Washington, DC sniper killings. Participants completed questionnaires during three waves of data collection: (1) during the sniper attacks (n=92); (2) within two weeks after the snipers were captured (n=45); and (3) six months later (n=43). Affectivity (measured by neuroticism) was significantly associated with state anxiety and positive emotions during all three time periods. Coping (measured by constructive thinking) predicted state anxiety and positive emotions during the shootings, but was unrelated to either outcome immediately after the attacks, and marginally related to them six months later. Consistent with the Dynamic Model of Affect, state anxiety and positive emotions were more strongly (and negatively) correlated with each other during the killings than they were after the snipers were apprehended. Taken together, these results support transactional models of stress that emphasize the interaction between dispositional and situational influences, and they suggest that affectivity reflects a fundamental set of reactions to one's environment, while coping dispositions result in more stress-specific responses. Additional theoretical and practical implications of these findings are also discussed.

What makes people anxious about pain? How personality and perception combine to determine pain anxiety responses in clinical and non-clinical populations.

Although anxiety has both dispositional and situational determinants, little is known about how individuals' anxiety-related sensitivities and their expectations about stressful events actually combine to determine anxiety. This research used Information Integration Theory and Functional Measurement to assess how participants' physical concerns sensitivity (PCS) and event expectancy are cognitively integrated to determine their anxiety about physical pain. Two studies were conducted - one with university students and other with anxiety clinic patients - in which participants were presented with multiple scenarios of a physically painful event, each representing a different degree of event probability from which subjective expectancies were derived. Independent variables included PCS (low, moderate, and high) and event expectancy (low-, medium-, high-, and non-probability information). Participants were asked to indicate their projected anxiety (dependent measure) in each expectancy condition in this 3 × 4 mixed, quasi-experimental design. The results of both studies strongly suggest that PCS and event expectancy are integrated additively to produce these pain anxiety scores. Additional results and their implications for the treatment of anxiety-related disorders are also discussed.

The cognitive processing of somatic anxiety: using functional measurement to understand and address the fear of pain

Although anxiety has both dispositional and situational determinants, little is known about how individuals’ anxiety-related sensitivities and their expectations about stressful events combine to determine anxiety. This research used Information Integration Theory and Functional Measurement to assess how participants’ anxiety sensitivity and event expectancy are cognitively integrated to determine their anxiety about physical pain. Two studies were conducted—one with university students and one with anxiety clinic patients—in which participants were presented with multiple scenarios of a physically painful event, each representing a different degree of event probability, from which subjective expectancies were derived. Independent variables included anxiety sensitivity (low, moderate, high) and event expectancy (low, medium, high, no probability information). Participants were asked to indicate their anxiety (dependent measure) in each expectancy condition in this 3 X 4 mixed, quasi-experimental design. The results of both studies strongly suggest that anxiety sensitivity and event expectancy are integrated additively to produce somatic anxiety. Additional results and their implications for the treatment of anxiety-related disorders are also discussed(AU)

The impact of group psychotherapy on social development in children with pervasive developmental disorders.

Thirty-nine children with a diagnosed pervasive developmental disorder (PDD) participated in homogeneous psychotherapy groups. Their social development was assessed at home and at school both before and after treatment. Significant improvements in social functioning were observed in both settings, and these gains were not attributable to demographic variables or cognitive development. This research provides psychometric validation for the Vineland Adaptive Behavior Scale (VABS; Sparrow, Balla, & Cicchetti, 1984) and the Tyminski Social Skills Checklist (SSC), a new index designed to assess children's social functioning in educational settings. The results suggest that group therapy may be an important modality for better understanding and developing crucial social skills among the growing number of children diagnosed with a pervasive developmental disorder.

Depression, constructive thinking and patient satisfaction in cardiac treatment adherence.

Many patients fail to adhere to prescribed treatment regimens, particularly patients who are depressed. This study examined the link between depression and adherence among 92 patients undergoing post-operative cardiac rehabilitation. Self-reported adherence was measured in terms of both general recommendations and specific health behaviours. Greater depression was associated with general - but not specific - adherence, and this relationship was mediated by lower satisfaction with their doctor - patient interactions. The link between depression and patient satisfaction was itself mediated by less constructive thinking among patients. These results suggest that adherence among cardiac rehabilitation patients may be enhanced by addressing patients' cognitive coping, and by improving the quality of their doctor - patient interactions.

Psychosocial factors in medical and psychological treatment avoidance: the role of the doctor-patient relationship.

A community sample of 1106 adults was examined to assess the impact of the doctor-patient relationship on participants' avoidance of treatment for a recognized medical or psychological problem. Of five aspects of participants' previous experience with their physicians, all but waiting time predicted participants' self-reported treatment avoidance. In two logistic regression models participants who felt their physicians listened more to their concerns were less likely to avoid treatment for both medical and psychological problems during the previous 12 months. These findings suggest that patients' perceptions of how they are treated by physicians may help explain why many people delay or avoid healthcare treatment, even when faced with a significant health problem.

Socioeconomic status and health: the role of sleep.

OBJECTIVE: Examine the role of sleep in the relationship between socioeconomic status (SES) and health. METHOD: Self-reported measures of income and education, sleep quantity and quality, and mental and physical health were obtained in a community sample of 1139 adults. RESULTS: More education was associated with higher income (p <.001), and higher income was associated with better physical health (p <.001) and psychological outcomes (p <.001). The effects of income on both mental and physical health were mediated by sleep quality (p values <.01), and sleep quantity was related to both measures of health (p values <.01) but to neither index of SES. CONCLUSION: Sleep quality may play a mediating role in translating SES into mental and physical well-being, and income seems to mediate the effect of education on sleep and, in turn, health.

The Long-term Physical Health and Healthcare Utilization of Women Who Were Sexually Abused as Children.

This article addresses the relationship between childhood sexual abuse and the long-term physical health and healthcare utilization of 148 female participants in an eight-year prospective study. Five factors of physical health emerged: General Health; Vegetative Health Symptoms; Colds and Flu; Gastrointestinal/Gynecological; and Healthcare Utilization. Abused females scored higher on the healthcare utilization and gastrointestinal/gynecological factors than comparison females. Abused females experiencing multiple perpetrators, violence, longer duration and older age at onset endorsed significantly more gastrointestinal/gynecological problems than did the other abused females and the comparison group. Findings suggest that: (1) sexual abuse affects long-term health outcomes and healthcare utilization; and (2) physical health sequelae of abuse may differentially affect females, depending upon the pattern of abuse characteristics.
