Purpose: The objective was to study how sedentary behaviour (SB) and physical activity (PA)change during a 6-months multimodal lifestyle intervention including a Multimodal Lifestyle Intervention, a Multimodal Lifestyle and Medical food intervention and a control subgroup, for people with prodromal Alzheimer's disease (AD). Further, the aim was to explore the predictive value of outcome expectancies and self-efficacy beliefs on level of PA in the two intervention subgroups.  Methods: A secondary analysis of existing data (n=66) from MIND-AD trial with a descriptive evaluation design was conducted. Descriptive and non-parametric statistical analysis were used for between- and within groups analysis. To explore the predictive value of a model with self-efficacy and outcome expectancies at baseline on PA at 6 months, regression analysis was conducted. Effect size was calculated for between-group and withingroup differences. Results: Objectively measured PA increased in the Multimodal Intervention subgroup. SB did not change during the intervention. Outcome expectancies for that impact of exercise is beneficial for health in the long run increased during the intervention. Participants higherinitial outcome expectancies for the impact of exercise would lead to less AD-related difficulties predicted higher PA level at 6 months. Self-efficacy for exercise or outcome expectancies for the impact of exercise on AD-related difficulties did not change during the intervention. Conclusions: PA increased in the Multimodal Intervention subgroup. This difference could not be shown with PA measured by questionnaire which indicates that objective measurements are better suited to measuring PA in people with prodromal AD than subjective measurements. Increased outcome expectancies for that impact of exercise arebeneficial for health in the long run demonstrate the participants strengthened intentions to improve their long-term health. Increasing outcome expectancies to manage AD-related difficulties can be an important part of interventions targeting PA in people with prodromal AD.

Based on previous research findings, which have found significant relationships between the hypothesized components of self-efficacy judgments for avoiding heavy drinking and actual levels of alcohol consumption in college students, the present study examined the role of anxious affect on self-efficacy for avoiding heavy drinking in college students. Specifically, it was hypothesized that heavy drinking subjects who were either high or low on dispositional social anxiety would report lower levels of self-efficacy for avoiding heavy drinking in response to feelings of social anxiety induced via anticipation of a self-disclosing heterosocial interaction. In addition, it was hypothesized that subjects who were high in dispositional social anxiety would report greater alcohol expectancies of social facilitation and tension reduction than subjects who were low in dispositional social anxiety. Subjects ill = 440) completed measures of alcohol expectancies, social anxiety, and quantity/frequency of alcohol use to identify heavy drinkers who were also either high or low in dispositional social anxiety. Identified subjects (n = 73) were then assigned to either an anxiety inducing or non-anxiety inducing condition and asked to complete measures of state anxiety and self-efficacy for avoiding heavy drinking in positive, negative, and socially anxious situations. Results failed to find a significant main effect for anxiety manipulation on self-efficacy for avoiding heavy drinking, but a main effect of ii dispositional social anxiousness was found on subjects' self-efficacy for avoiding heavy drinking in negative and socially anxious situations. The results of the study also failed to find significant relationships between alcohol expectancies of tension reduction and dispositional social anxiousness, but did find a significant positive relationship between social anxiety and alcohol expectancies of social facilitation. Lastly, exploratory analyses found significant relationships between positive and negative alcohol expectancies and self-efficacy for avoiding heavy drinking in socially anxious situations. Moreover, significant relationships were also found between alcohol expectancies and the frequency of drinking episodes and actual quantity consumed. Results are discussed in terms of the relationship between affect, self-efficacy, and outcome expectancies and implications for alcohol intervention programs with college students. / Master of Science

Students tend to perform at the academic level expected of them. Although most expectation research has centered investigation of decontextualized teacher-student dyads to understand whether students behaviorally confirm their teacher’s expectation, we now know that expectations operate at whole-group or system levels. Since underestimation is more common within historically marginalized learning communities, these student groups can experience comprehensive systems of underestimation at the level of the institution, with lifelong consequences for success and wellbeing. While intervening in such systems is possible (e.g., changing beliefs or practices to ensure over-estimation), it remains difficult because researchers do not yet understand how academic expectations are constructed or what governs the process. This is essential knowledge for generating more equitable expectation systems. Academic expectations constitute a complex and dynamic system. However, methodologies traditionally used to investigate them have collectively assumed otherwise, likely masking the pervasiveness of underestimation in marginalized settings. In this ethnographic case study I examine expectation co-construction in one 11th grade classroom serving marginalized students. Analyzing over seven hours of classroom discourse and fieldnotes across a five week span, participant recall interviews, learning artifacts, and archival data, I investigate three interdependent system facets: teachers’ and students’ expectation-related discourse; sociocultural inputs operating at multiple levels; and the emerging role identities of teachers and three focal students in relation to expectations. I describe and map an integrated network of 27 emerging expectations, and explain the how and why of their situated co-construction by members of the learning community. I argue that individuals’ awareness of their own contributions to the everyday behaviors, beliefs, and discourse that construct and reproduce underestimated expectations is critical to disrupting such systems. This study offers practitioners and researchers an adaptable methodology to build this awareness and inform subsequent interventions. / Educational Psychology

<p>This study explores older adolescents’ positive and negative beliefs about illicit drug use from a preventive perspective. By positive beliefs is meant positive expectancies and benefit perceptions. By negative beliefs is meant negative expectancies and risk perceptions. The choice of studying beliefs originates from the assumption that there is much to gain for prevention in considering the target audience’s starting point. An appraisal of the extent to which positive and negative beliefs are held suggests the margins for change.</p><p>The data used for the study derive from a survey conducted among a sample of third-year students in upper secondary school in the greater Stockholm area (n=2104). Overall, findings demonstrate that high negative beliefs are held and that positive beliefs to some extent are held. While this being the general trend, marked differences emerge between individuals who have used illicit drugs and individuals who have not. By and large, experienced individuals rate the negative sides as lower and the positive sides as higher than the other group. Substantial differences are found among lifetime users of illicit drugs as well. Those who have used illicit drugs more frequently during the last 12 months differ in particular from those who have refrained during this period. The differences are dramatic in some cases. In addition, consistent differences are documented between the sexes. Males are found to hold lower negative beliefs and higher positive beliefs across most measures employed. Few systematic relationships are found between other variables and outcomes.</p><p>Plausible explanations for the findings are discussed theoretically and potential implications for drug prevention are highlighted. A saturation hypothesis is introduced in order to accentuate that the overall room for change in negative beliefs probably is limited. Conversely, the fact that positive beliefs are held to a certain degree suggests a belief domain with change potential.</p>

Evidências recentes na literatura apontam um elevado consumo de álcool entre estudantes universitários. Expectativas relacionadas aos efeitos do uso de álcool têm sido associadas tanto ao início quanto à manutenção do beber de jovens. De forma análoga, o grupo de pares é um aspecto de destacada relevância sobre o comportamento dos jovens, inclusive no que se refere ao uso de álcool. Por sua vez, tanto expectativas quanto grupo de pares podem modular de forma diferente o comportamento do beber de homens e de mulheres. O objetivo deste estudo foi avaliar diferenças de gênero sobre o uso de álcool, expectativas relacionadas aos efeitos do uso de álcool e o envolvimento com o grupo de pares de risco para o uso de álcool entre estudantes universitários da área da saúde. Participaram 238 estudantes (105 homens) de todos os anos dos cursos de Medicina e Fisioterapia da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo. Estudantes preencheram um questionário estruturado autoaplicável contendo os instrumentos AUDIT (Alcohol Use Disorders Identification Test), para avaliar o uso de álcool, AEQ-A (Alcohol Expectancy Questionnaire Adolescent Form), para avaliar as expectativas dos efeitos do uso de álcool, e DUSI (Drug Use Screening Inventory), para avaliar o grupo de pares. A prevalência do uso de álcool no ano foi de 92,1% entre os homens e de 81,2% entre as mulheres (X²=10,87; p=0,02). Homens também apresentaram maior prevalência do padrão de uso problemático de álcool (X²=8,19; p<0,01) e de binge drinking (X²=8,13; p<0,01). Expectativas de transformações globais positivas (Z=-2,12; p=0,03) e de melhora no desempenho sexual (Z=-2,76; p<0,01) associadas ao consumo de álcool foram mais significativamente relacionadas ao gênero masculino. Entretanto, não houve diferenças de gênero na pontuação média para a escala de relação de pares do instrumento DUSI (Z=-1,67; p=0,09). Apesar do elevado uso de álcool para ambos os gêneros, homens apresentaram maior prevalência de uso de álcool no ano, uso problemático e binge. Grupo de pares parece ser um possível fator de vulnerabilidade para o uso de álcool, independente do gênero. Entretanto, expectativas se correlacionaram de maneira positiva com o uso de álcool apenas entre os homens. Esses resultados podem indicar que diferenças de gênero podem ter importante papel na elaboração de estratégias de prevenção mais precisas e eficazes sobre o uso de álcool. / Recent evidences in scientific literature have indicated an increasing alcohol consumption in university students. Alcohol expectancies have been associated to the beginning and maintenance of drinking by young adults. Peer group is also a relevant aspect on young behavior, mainly on alcohol use. Both, alcohol expectancies and peer group can modulate drinking behavior of men and women by different pathways. This study aimed to evaluate gender differences of alcohol use, alcohol expectancies and peer relationship in university students of the health area. Observational, transversal study design on a convenience sample of 238 university students (105 men) from Medicine and Physiotherapy courses of the School of Medicine of Ribeirão Preto of University of São Paulo. Students completed self-reported questionnaire, including AUDIT (Alcohol Use Disorders Identification Test), to evaluate alcohol use, AEQ-A (Alcohol Expectancy Questionnaire - Adolescent Form), to evaluate alcohol expectancies, and DUSI (Drug Use Screening Inventory), to evaluate peer group. 92.1% of men and 81.2% of women declared to have drank alcohol in the last 12 months (X²=10.87; p=0.02). Men scored significantly higher on prevalence of problematic alcohol use and binge drinking (X²=8.13; p<0.01). Expectancies of positive global transformations (Z=-2.12; p=0.03) and sexual enhancement (Z=-2.76; p<0.01) associated to alcohol consumption were more evident in male. However, no gender differences on peer relationship was observed (Z=-1.67; p=0.09). Despite of increased alcohol use for both gender, male have presented a greater prevalence of alcohol use in the last 12 months, problematic alcohol use and binge drinking. Peer group may be a possible vulnerability factor on alcohol consumption, independent of gender. However, alcohol expectancies presented a positive correlation to alcohol use only in men. Results indicate that gender differences may have an important role for the development of more efficient strategies for alcohol abuse prevention.

Background:Non-medical use of prescription opioids (NMUPO) has become a clear threat to public health. Young adults (aged 18 to 25) have a high risk of NMUPO. My prior work on Chinese undergraduates indicates a high prevalence of lifetime NMUPO (49.2%). Health behavior theories propose that outcome expectancies are robust psychosocial determinants of substance use. Literature has identified the influence of outcome expectancies on alcohol and drug use. However, the role of outcome expectancies in NMUPO in China is unknown, and a scarcity of a valid measures for NMUPO outcome expectancies may be a barrier. Our previous research also found an association of cultural orientation with NMUPD in Chinese college students, implying that cultural orientation may affect NMUPD-related perceptions, such as outcome expectancies. The purposes of this study were to (1) conduct initial work to develop and validate an NMUPO outcome expectancies scale (NMUPOES) for Chinese college students; (2) examine the association of cultural orientation with factors identified in NMUPOES. Method: Partial data (n = 202) derived from a bigger online dataset collected from 849 undergraduates (average age = 19.65) at two universities in Beijing and Macau in Jan-April 2017 was used in this study. Participants completed the NMUPOES and reported their past-3-month NMUPO and cultural orientation. Exploratory factor analysis, confirmatory factor analysis, and structural equation modeling were employed to test the study hypotheses. Results: Findings suggested four subscales in the 50-item NMUPOES (i.e., social enhancement and tension reduction, academic enhancement, physiological discomfort, and guilt and dependence) and two higher-order factors (i.e., positive expectancies and negative expectancies). All subscales were positively correlated and had good internal consistency. The negative expectancies scale was negatively associated with past-3-month NMUPO. No significant association was found between cultural orientation and the two expectancy factors. Conclusion:NMUPOES is a psychometrically appropriate measure of NMUPO expectancies for Chinese college students. Future research may validate the NMUPOES using a large sample size in both clinical and non-clinical populations in China. An intervention program tailored to outcome expectancies may be beneficial to reduce the risk of NMUPO in Chinese college students.
