Is dispositional optimism or dispositional pessimism predictive of ideal cardiovascular health? The Young Finns Study

Objective: We examined the independent association between dispositional optimism compared to dispositional pessimism and ideal cardiovascular health (defined by the American Heart Association).

Design: A prospective design with a study sample of 1113 participants aged 24–39 years from the longitudinal Young Finns Study.

Main outcome measures: Ideal cardiovascular health (comprised of seven ideal cardiovascular health metrics) was measured in 2001. The ideal cardiovascular health metrics were reassessed in 2007.

Results: Low pessimism rather than high optimism was a better predictor of ideal cardiovascular health in 2007. When examining the association between optimism and pessimism and the seven ideal cardiovascular health metrics in 2007 (BMI, diet, physical activity, smoking status, blood pressure, total cholesterol and plasma glucose), low pessimism predicted non-smoking status, ideal physical activity and eating a healthy diet, while high optimism was associated with eating a healthy diet.

Conclusion: Our findings suggest that low pessimism rather than high optimism is associated with ideal cardiovascular health, especially with health behaviours such as not smoking, being physically active and eating a healthy diet. Socio-economic status was the potential mediating or confounding factor. Future studies should examine the differential meaning of the optimism/pessimism concepts to further clarify their relation to health outcomes.     

Prospective Relations between Overeating,Loss of Control Eating,Binge Eating,and Depressive Symptoms in a School-Based Sample of Adolescents

A sample of 353 community adolescents (grades 9 to 12, 57.6 % female) participated in a 2-wave longitudinal study of eating behaviors (overeating, loss of control eating [LOC], and binge eating) and depression. The study addresses 4 hypotheses. (1) The prospective relations between eating behaviors and depressive symptoms will be reciprocal, with each predicting the other over time. (2) These relations will be stronger for girls than for boys. (3) These relations will be stronger for adolescents with high (not low) body mass index (BMI). (4) LOC will show incremental predictive utility in relation to depressive symptoms over and above overeating. Evidence supported reciprocal relations between binge eating and depressive symptoms and between overeating and depressive symptoms, but not between LOC and depressive symptoms. Sex and BMI did not substantially moderate these relations. Taken separately, overeating but not LOC predicted depressive symptoms. Taken together, neither predictor was significant controlling for the other. Results raise questions about the importance of LOC alone in predicting depressive symptoms in adolescence.     

Challenging body weight: evidence from a community-based intervention on weight,behaviour and motivation

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention within a commercial fitness centre on body weight, moderate to vigorous physical activity (MVPA), dietary intake, and behavioural regulations for exercise and healthy eating. Using a quasi-experimental design, the intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. Outcome variables were assessed at three time points over a six month period. Results showed a significant interaction for body weight (p = .04) and dietary changes (p < .05) following the weight loss challenge but were not maintained across the six month period. Changes in behavioural regulations favoured the intervention condition. Results imply that a 12 week weight loss challenge within a commercial fitness centre may be effective at prompting short-term weight loss and support the internalization of behavioural regulations specific to healthy eating and exercise.     

Resisting temptation: alcohol specific self-efficacy mediates the impacts of compensatory health beliefs and behaviours on alcohol consumption

Awareness of health risks linked with excessive alcohol consumption appears to have little influence on how much some people drink. Compensatory health beliefs (CHBs), in which the consequences of unhealthy behaviour are considered to be neutralised by additional healthy behaviours, are one way of justifying poor health choices. Currently, the role of CHBs within the context of drinking behaviour is not well understood. This research examined associations between alcohol specific compensatory health beliefs (ACH-Beliefs) and behaviours (ACH-Behaviours), alcohol consumption and alcohol specific self-efficacy (ASE), via an online survey completed by 249 participants, aged 18 + years (63.1% female; M age = 41.62 years; SD = 14.80). Higher ACH-Beliefs were associated with increases in ACH-Behaviours. While both predicted alcohol consumption, a greater proportion of variance was explained by ACH-Behaviours. ASE was a significant mediator of those relationships, suggesting that those with higher ASE may be better equipped to regulate drinking behaviour. Recommendations for future research include measuring both CHBs and behaviours within an experimental design, and further investigation of related cognitions such as compensatory behaviour intentions. Alcohol misuse interventions may wish to consider the potential roles of CHBs and behaviours in facilitating maladaptive coping strategies, and how addressing these may reduce harms.     

‘I feel better when…’: An analysis of the memory-experience gap for peoples’ estimates of the relationship between health behaviours and experiences

Objective: People often overestimate how strongly behaviours and experiences are related. This memory-experience gap might have important implications for health care settings, which often require people to estimate associations, such as “my mood is better when I exercise”. This study examines how subjective correlation estimates between health behaviours and experiences relate to calculated correlations from online reports and whether subjective estimates are associated with engagement in actual health behaviour.

Design: Seven-month online study on physical activity, sleep, affect and stress, with 61 online assessments.

Main Outcome Measures: University students (N = 168) retrospectively estimated correlations between physical activity, sleep, positive affect and stress over the seven-month study period.

Results: Correlations between experiences and behaviours (online data) were small (r = ?.12–.14), estimated correlations moderate (r = ?.35–.24). Correspondence between calculated and estimated correlations was low. Importantly, estimated correlations of physical activity with stress, positive affect and sleep were associated with actual engagement in physical activity.

Conclusion: Estimation accuracy of relations between health behaviours and experiences is low. However, association estimates could be an important predictor of actual health behaviours. This study identifies and quantifies estimation inaccuracies in health behaviours and points towards potential systematic biases in health settings, which might seriously impair intervention efficacy.     

Examination stress and changes in mood and health related behaviours

Abstract

The present exploratory study evaluated the effect of stress (an examination period) on changes in mood and health related behaviours. 83 medical students completed measures of mood and health related bchaviours at baseline and four weeks later either during their examinations period (the stress condition) or after a comparative control period (the control condition). All subjects also completed ratings of stress mediating variables: social support, perceived control and coping style at baseline. The results showed deterioration in mood in terms of increases in depression and anxiety and changes in health related behaviours in terms of increased numbers of subjects who identified thcmsehes as smokers, and dcmascs in alcohol consumption, exercise and food intake in subjects in the stress condition. The results also suggest that social support moderated the effects of the examination stress and was related to greater decreases in smoking, decrcases in alcohol craving and increases in eating behaviour. In addition, an avoidance coping style (problem avoidance, wishful thinking) was related to greater decreases in eating behaviour. 'Ihe nsults an discussed in the context of the stress/illness link and the role of behavioural change.     

Testing compensatory health beliefs in a UK population

Compensatory health beliefs, beliefs that healthy behaviours can compensate or neutralise unhealthy behaviours, have been proposed as one way of understanding why people engage in health-risk behaviours (Knäuper, B., Rabiau, M., Cohen, O., & Patriciu, N. (2004). Compensatory health beliefs scale development and psychometric properties. Psychology and Health, 19, 607–624). However, measuring compensatory health beliefs has proved a challenge, with several recent studies being unable to replicate the psychometric properties of Knäuper et al.'s (2004) scales. The aims of this study were to: (1) test the factor structure of the compensatory health beliefs scale in the UK, (2) examine the predictive validity of the scale by testing the relationships between compensatory health beliefs and health behaviours over a six-month time interval and (3) assess the 6-month test–retest reliability of the scale. A total of 393 participants completed measures of compensatory health beliefs and health behaviours at two time points separated by six months. The findings were potentially problematic for research into compensatory health beliefs: the factor structure was not confirmed, there was little evidence of predictive validity, and test–retest reliability was poor. Further research is required to understand the operation of compensatory health beliefs and to develop the measurement of compensatory health beliefs.     

Self-efficacy,planning, and preparatory behaviours as joint predictors of physical activity: A conditional process analysis

Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual’s level of self-efficacy.

Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.

Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.

Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity.     

The role of pain behaviour and family caregiver responses in the link between pain catastrophising and pain intensity: A moderated mediation model

Objectives: This study investigated the mediating role of pain behaviours in the association between pain catastrophising and pain intensity and explored the moderating role of family caregivers’ responses to pain in the link between pain behaviours and pain intensity.

Methods: The sample consisted of 154 chronic pain patients and their family caregivers. Patients completed questionnaires regarding pain intensity, pain catastrophising, pain behaviours and their caregivers’ responses to their pain. Family caregivers reported their responses to the patients’ pain.

Results: Pain catastrophising was associated with pain intensity (r = 0.37) and pain behaviours partly mediated this association. The positive association between pain behaviours and pain intensity was significant only if patients reported that their family caregivers showed high levels of solicitous (effect = .49) and distracting responses (effect = .58), and if caregivers reported to show high levels of solicitous responses (effect = .51). No support was found for negative responses as a moderator neither based on patients’ perception of negative responses nor based on caregivers’ perception of negative responses.

Conclusions: The findings are in line with the idea that family caregivers’ solicitous and distracting responses convey to patients that their condition is serious, which may reinforce patients’ pain and pain behaviours, especially in those who catastrophise.

Externalizing behaviours of Turkish-Dutch and Moroccan-Dutch youth: The role of parental cultural socialization

The present study examines whether perceived parental cultural socialization (e.g., encouraging cultural practices, traditions, language and cultural pride) is negatively associated with externalizing problem behaviours (e.g., fighting, expression of anger, lying and stealing) among Turkish-Dutch (n = 143) and Moroccan-Dutch (n = 164) youth (age 14–18), with ethnic in-group connectedness as a mediator. The results show that Turkish-Dutch youth, who report more cultural socialization efforts by their parents, are less likely to exhibit externalizing behaviours, because of their increased connectedness to the ethnic in-group. For Moroccan-Dutch youth, however, in-group connectedness is lower and we find no indirect effect of perceived parental cultural socialization on externalizing behaviours. We conclude that Turkish-Dutch youth seem to reap mental health benefits from what they perceive as their parents’ cultural socialization efforts. Thus, it is important to study ethnic differences in parental cultural socialization to enhance youth development across diverse youth populations in Europe.     

Through the eyes of dieters: Biased size perception of food following tempting food primes

Why do some dieters succeed in controlling their diet while others do not? This research focused on a perceptual process—size perception of food objects—that may moderate the success of dieters in self-control dilemmas. We assessed successful and unsuccessful dieters' size perception of palatable food (Study 1) and diet-food (Study 2) after pre-exposing them to tempting food primes. Dieters perceived palatable food as bigger when primed with tempting food (vs. control prime), regardless of self-regulatory success in dieting (Study 1). Palatable food thus looms larger for both unsuccessful and successful dieters when in a “hot” state. In contrast, the perceived size of diet-food was increased by a tempting food prime only for successful dieters, but decreased for unsuccessful dieters (Study 2). These results are interpreted in terms of differences in the mental accessibility of competing goals (eating enjoyment vs. dieting) in successful vs. unsuccessful dieters. Indeed, when the dieting goal was made accessible for all dieters by a diet prime, even unsuccessful dieters perceived diet-food as bigger (Study 2). This research provides insight into a perceptual process that may be detrimental or beneficial in resolving self-control conflicts in the domain of eating and dieting behavior—and probably other domains of self-control as well.     

Feeling bad about progress does not lead people want to change their health behaviour

Objective: When do people decide to do something about problematic health behaviours? Theoretical models and pragmatic considerations suggest that people should take action when they feel bad about their progress – in other words, when they experience negative progress-related affect. However, the impact of progress-related affect on goal striving has rarely been investigated.

Design and Methods: Study 1 (N = 744) adopted a cross-sectional design and examined the extent to which measures of progress-related affect were correlated with intentions to take action. Study 2 (N = 409) investigated the impact of manipulating progress-related affect on intentions and behaviour in an experimental design.

Results: Study 1 found that, while engaging in health behaviours had the expected affective consequences (e.g. people felt bad when they were not eating healthily, exercising regularly or limiting their alcohol consumption), it was feeling good rather than bad about progress that was associated with stronger intentions. Study 2 replicated these findings. Participants induced to feel good about their eating behaviour had marginally stronger intentions to eat healthily than participants led to feel bad about their eating behaviour.

Conclusion: The findings have implications for interventions designed to promote changes in health behaviour, as well as theoretical frameworks for understanding self-regulation.     

Resisting temptation of unhealthy food: interaction between temptation-elicited goal activation and self-control

Counteractive control theory suggests that the cognitive accessibility of a goal in response to a temptation cue predicts self-regulation of behaviour consistent with that goal. The current study provided a novel test of this effect in the eating domain, exploring the moderating role of trait self-control. A sample of 124 women (18–25 years) completed a lexical decision task to assess cognitive accessibility of the weight-management goal after food temptation priming. Eating self-regulation was operationalised as unhealthy snack food intake measured in a task disguised as a taste-test. Participants completed trait self-control and temptation experience intensity measures. Cognitive accessibility predicted lower food intake, but only among high self-control participants. The relationship was mediated by temptation experience intensity: participants with high cognitive accessibility felt less tempted, and subsequently ate less food. Results suggest that changing the processes underlying the temptation experience, rather than the cognitive accessibility of a goal may more effectively enhance self-regulation among low self-control individuals.     

Situation Taxonomy and Behavioral Diagnosis Using Prospective Self-Monitoring Data: Application to Dietary Adherence in Patients with Type 1 Diabetes

The goals of this study were to create a taxonomy of problem situations for diet adherence in persons with insulin-dependent diabetes mellitus (Type 1 diabetes) and a behavioral diagnosis by grouping patients together who have similar adherence problems. In study one, 29 patients with Type 1 diabetes kept food diaries for 4 weeks. Adherence was assessed using eight behavioral measures: (1) compliance with a meal plan, (2) energy intake, (3) protein, (4) carbohydrates, (5) fat, (6) self-reported overeating, (7) self-reported undereating, and (8) ratings of impulsive eating. The occurrence of each behavior was quantified in a wide range of situational contexts including meal, social context, physical location, and mood. Cluster analysis of behaviors, situations, and behaviors-in-situations was used to create a hierarchical classification model consisting of five major categories of adherence problems: (1) compliance with meal plan, (2) undereating, (3) overeating, (4) impulsive eating, and (5) lifestyle differences. Within each category, situations were associated with everyday eating habits and special circumstances such as social events, and meals in restaurants. Grouping patients based on the similarity of their adherence problems resulted in five diagnostic groups: (1) emotional binge eaters, (2) restrained eaters, (3) unrestrained eaters, (4) undereaters, and (5) cyclical diet bingers. In study two, 28 subjects kept diaries during an intervention program designed to enhance dietary adherence. Study two results were similar to study one. Situation taxonomy and behavioral diagnosis are potentially useful ways to understand the intervention needs of those attempting maintaining dietary behavior changes.     

Job crafting and job performance: A longitudinal study

In this three-wave study (N = 288), we examined whether job crafting intentions and work engagement led to actual job crafting behaviours and, in turn, to higher levels of prospective work engagement and job performance. We used the Job Demands-Resources model as a theoretical framework and defined job crafting as the self-initiated changes that employees make in their job demands and resources. One month after reporting their job crafting intentions, respondents rated their actual job crafting behaviours. Again one month later, they rated their levels of work engagement, in-role performance, and organizational citizenship behaviour towards individuals (OCBI). Results of structural equation modelling showed that job crafting intentions and work engagement significantly related to actual job crafting, which, in turn, related to higher levels of work engagement, while controlling for job characteristics. Results further showed that engaged employees performed better on their in-role tasks but did not perform more OCBIs. The findings suggest that employees can increase their own work engagement and job performance through job crafting.     

The structure and correlates of a measure of prosocial moral reasoning in adolescents from Spain

The study was designed to examine the structure and correlates of a measure of prosocial moral reasoning in a sample of young and middle-aged adolescents. Participants were 1,556 students (53% male, M _age = 13.12 years, SD = 0.87) from Valencia, Spain, who completed paper-and-pencil measures of prosocial moral reasoning (PROM), empathy, prosocial behaviours, and aggression. As expected, a series of confirmatory factor and structural equation modelling analyses revealed a four-factor solution of the PROM to have the best fit (as compared to alternative models) among Spanish youth (across gender and grade). Moreover, higher level and other-oriented forms of prosocial moral reasoning were generally positively related to empathy and prosocial behaviours, and negatively related to aggression. In contrast, generally, lower level and self-focused modes of prosocial moral reasoning were negatively related to such prosocial tendencies, and positively related to aggression. Discussion focuses on the usefulness of the PROM, its relations to theoretically relevant correlates, and its usefulness to study the development and universality of prosocial moral development.     

Learning and memory in the Port Jackson shark,Heterodontus portusjacksoni

Basic understanding of the fundamental principles and mechanisms involved in learning is lacking for elasmobranch fishes. Our aim in this study was to experimentally investigate the learning and memory capacity of juvenile Port Jackson sharks, Heterodontus portusjacksoni. Sharks (N = 30) were conditioned over a 19-day period to associate an underwater LED light or stream of air-bubbles [conditioned stimulus (CS)] with a food reward [unconditioned stimulus (US)], using three procedures (delay, trace and control). During experiments, the CS signalled at a random time between 180 and 300 s for 30 s (six times per day). For the delay the US overlapped in time with the CS, for the trace the US delivered 10 s after the CS and for our control the US was delivered at random time between 180 and 300 s after the CS. H. portusjacksoni sharks trained in all procedures improved consistently in their time to obtain food, indicative of Pavlovian learning. Importantly, the number of sharks in the feeding area 5 s prior to CS onset did not change over time for any procedures. However, significantly more sharks were present 5 s after CS onset for delay for both air-bubble and light CS. Sharks trained in the delay and trace procedures using air-bubbles as the CS also displayed significantly more anticipatory behaviours, such as turning towards the CS and biting. Sharks trained with the light CS did not exhibit such behaviours; however, trace procedural sharks did show a significant improvement in moving towards the CS at its onset. At 20 and 40 days after the end of the conditioning experiments, some sharks were presented the CS without reward. Two sharks trained in the delay procedure using air-bubbles as the CS exhibited biting behaviours: one at 20 and the other at 40 days. This study demonstrates that H. portusjacksoni have the capacity to learn a classical conditioning procedure relatively quickly (30 trials during 5 days) and associate two time-separated events and retention of learnt associations for at least 24 h and possibly up to 40 days.     

The interactive effects of temperament and maternal parenting on toddlers' externalizing behaviours

The present study aimed to determine the potential moderating effects of temperamental traits on the relation between parenting and toddlers' externalizing behaviours. For that purpose, this study examined the interplay between temperament and maternal parenting behaviours in predicting the level as well as the development of toddlers' externalizing behaviours. Participants were 115 boys (wave 1, M=16.9 months; wave 2, M=23.2 months) and their mothers, who were observed in a 13‐min structured play session at home. With regard to the prediction of the level of externalizing behaviours at wave 1, main effects were found for children's temperamental characteristics. In addition, maternal negative control interacted significantly with children's inhibitory control in predicting this level of externalizing behaviours. The findings with regard to the development of externalizing behaviours showed that the effects of maternal negative control and lack of maternal sensitivity were stronger for toddlers with a difficult temperament: maternal negative control and lack of maternal sensitivity were related to an increase in externalizing behaviours for temperamentally difficult children only. These results offer support for the goodness‐of‐fit hypothesis, stressing the idea that the effects of temperament and the social environment depend to a large extent on their interplay.
