Increasing Positive Health Behaviors in Adolescents with Nutritional Goals and Exercise

Research has documented that low-income urban youth are at risk for obesity and related health problems. Our goal was to develop a brief, developmentally informed intervention to increase positive health behaviors (e.g., diet and exercise) among low-income, minority adolescents. Our study was designed to examine the feasibility and potential impact of our single session intervention that was delivered in a primary care setting. The participants were 100 adolescents from an urban adolescent medicine clinic who were randomly assigned to one of two conditions: a) a 3–5?min goal-only session or b) a 15–20?min motivationally enhanced intervention. Health behaviors and individual characteristics (i.e., autonomous motivation, self-efficacy) were assessed at baseline and re-assessed at follow-up 1 month later with 53?% of the youth completing the follow-up assessment. Those in the enhanced intervention group were more likely to participate in the follow-up as were those who reported higher baseline motivation and self-efficacy. Both groups reported statistically significant health behavior improvements over time and older adolescents reported more improvements. The two conditions did not significantly differ in reported health improvements. Self-efficacy predicted improvements in self-reported fruit and vegetable intake at follow-up. Results support that a brief “chat” with adolescents about their personal goals and values appears to have the potential to increase their positive health behaviors and appears to be useful as a preparatory intervention for weight management efforts for urban teens. The study demonstrates the feasibility and potential efficacy of implementing this 20?min intervention into primary care settings, thereby helping urban youth focus on their individualized goals, values, and motivations for health.     

Self‐regulation as relating to one's ideal possible self

People dream of countless ideal possible selves they hope to become, but they have a difficult time actualizing them. In the present work, we review and integrate prior research regarding possible selves, self‐regulation, and interpersonal relationships. We draw on multiple perspectives to define ideal possible selves and clarify their structure. We suggest that framing self‐regulation of an ideal possible self as relating to one's ideal possible self affords an explanation that ideal possible selves can (but sometimes do not) motivate current self‐regulation. We discuss two ways ideal possible selves motivate current self‐regulatory behavior: through increased vividness of the ideal possible self and through commitment to the ideal possible self. These routes pave the way for future research designed to help people increase their efforts toward becoming their ideal possible selves.     

Effects of a Self-Efficacy Intervention on Exercise: The Moderating Role of Diabetes and Cardiovascular Diseases

The paper examines the influence of a brief tailored intervention on exercise levels and self-efficacy beliefs in the context of participants' health status. We hypothesised that the effects of a self-efficacy intervention targeting more frequent exercise would be larger among people with diabetes or cardiovascular diseases (CVD), compared to the effects of the intervention among individuals without such diseases. The treatment was tailored to participants' self-efficacy and was delivered by e-mail. Data from 187 adults were collected at two measurement points, with a 6-month follow-up. Participants reported their exercise frequency and self-efficacy scores, along with several social-cognitive variables, such as risk perception and intentions. Besides the influence of the intervention on exercise and self-efficacy, we found that the treatment effects were moderated by diabetes or CVD: Participants with those illnesses benefited from the intervention, compared to people without such diagnosis. Among participants with CVD or diabetes the effects of the intervention on behavior were mediated by changes in efficacy beliefs. The results indicated that a parsimonious treatment may contribute to change in exercise over the longer term, in particular among individuals with a disease related to the respective behavior. Changes in behavior may be explained by changes in respective beliefs.     

Possible selves and delinquency

The relationship between possible selves and delinquency is explored. In this study, 238 youths between the ages of 13-16 who varied in the degree of their delinquency were asked to describe their possible selves. Although many similarities were found among their hoped-for selves, the groups of youth differed markedly in the nature of their expected and feared selves. The balance between expected possible selves and feared possible selves was the particular focus. Balance is hypothesized to occur when expected possible selves are offset by countervailing feared selves in the same domain (e.g., expecting a job, but fearing being unemployed). It was found that the officially nondelinquent youths were quite likely to display balance between their expectations and fears, unlike the most delinquent youth. In contrast, a conventional measure of self-esteem that indicates how people feel about themselves currently did not predict degree of delinquency.     

Doubting one’s doubt: A formula for confidence?

People feel, think, and act differently when doubt rather than confidence is accessible. A traditional perspective on the accessibility of doubt holds that multiple sources of doubt activation should lead to increased levels of uncertainty. In contrast, we find that under some conditions two sequential sources of doubt activation result in decreased levels of uncertainty. We suggest that this follows from a meta-cognitive process in which people come to “doubt their doubt.” In Study 1, individuals with chronically accessible uncertainty who were further exposed to an uncertainty manipulation paradoxically reported reduced uncertainty. In Study 2, participants were first primed with doubt or certainty and then exposed to a manipulation associated with either confidence (i.e., head nodding) or doubt (head shaking). Supporting the idea that people can either trust or doubt their own doubts, head nodding (vs. shaking) accentuated (vs. attenuated) the impact of the initial doubt vs. certainty manipulation. These findings advance the literature on meta-cognition, self-doubt, and embodiment, and may have clinical applications.     

Expecting to Work,Fearing Homelessness: The Possible Selves of Low‐Income Mothers1

We explored the content of possible selves of low‐income mothers and the strategies they have to work on their possible selves. Positive expected possible selves focus on getting a job, making ends meet, and caregiving. Negative to‐be‐avoided possible selves focus on failing to make ends meet, losing (or not getting) jobs, and problems with mental health. Immediate social context—rather than demographic characteristics or global work–family variables—was associated with content of possible selves. Controlling for demographic and work–family variables, job‐focused possible selves (and strategies to attain them) were more salient; and caregiving and mental‐health‐related possible selves were less salient to mothers in job‐training programs vs. welfare offices.     

Exercise as a buffer of life stress: a prospective study of adolescent health

The hypothesis that physical exercise provides benefits to individuals under periods of life stress has rarely been subject to empirical verification. This article presents the results of a longitudinal study of stress and well-being in adolescence in which the ability of exercise to buffer stress-induced deteriorations in physical health was examined. In accordance with predictions, prospective analyses revealed that the negative impact of stressful life events on health declined as exercise levels increased. These findings suggest that exercise may be a valuable resource for combating life stress. Discussion centers on possible mediating mechanisms and on the practical implications of the results.     

Future orientation in the self-system: possible selves, self-regulation, and behavior

Possible selves are representations of the self in the future. Early theoretical accounts of the construct suggested that possible selves directly influence motivation and behavior. We propose an alternative view of possible selves as a component in self-regulatory processes through which motivation and behavior are influenced. We demonstrate the advantages of this conceptualization in two studies that test predictions generated from theoretical models of self-regulation in which the possible selves construct could be embedded. In one study, we show how viewing possible selves as a source of behavioral standards in a control-process model of self-regulation yields support for a set of predictions about the influence of possible selves on current behavior. In the other study, we examine possible selves in the context of an interpersonal model of self-regulation, showing strong evidence of concern for relational value in freely generated hoped-for and feared selves. These findings suggest that the role of possible selves in motivation and behavior can be profitably studied in models that fully specify the process of self-regulation and that those models can be enriched by a consideration of future-oriented self-representations. We offer additional recommendations for strengthening research on possible selves and self-regulation.     

Roles of Boredom and Life Goals in Juvenile Delinquency1

The relationship between possible selves and boredom in juvenile delinquency was examined in 418 high school students. The construct Possible Selves refers to the representation of the self that each person would like to become, could become, and is afraid of becoming. Participants who acknowledged high levels of delinquent behaviors reported more negative possible selves, a higher tendency to experience boredom, and fewer positive possible selves than did adolescents who engaged in lower levels of delinquent behaviors. Also, the number of negative possible selves, the number of positive possible selves, boredom proneness, and gender accounted for 32% of the variance in juvenile delinquency. Overall, the results provide evidence that boredom and a negative view of one's future play a significant role in adolescent delinquent behavior.     

Possible selves in patients with right- versus left-onset Parkinson’s disease

Possible selves can be used to self-regulate and guide behavior towards what is desired to be achieved or avoided in life. Previous work suggests laterality effects exist within the brain regarding approach and avoidance systems to achieve self-regulation. A modified version of the possible selves task was administered to 45 patients with PD (22 right-onset and 23 left-onset) and 25 community dwelling control subjects (CS). Only 11.1% of patients exhibited balance among their hoped-for and feared possible selves versus 28% of CS. More right-onset patients used a promotion strategy whereas more left-onset patients used a prevention strategy. Patients with left-onset PD thought more about their feared selves, exhibiting reduced goal-directed behavior. Findings among the left-onset group indicate relative dependence of self-regulation on right-sided avoidance brain systems. This may point to an inability to move away from negative outcomes and to work towards rewarding outcomes, which could affect psychological health.     

Coping With Life Events Through Possible Selves1

This study examines the integration of life events into the possible‐selves repertoire and explores the potential relationship between event‐related possible selves and coping. The sample consisted of 198 participants between 18 and 84 years old. Participants were given the Possible Selves Interview, the Social Readjustment Rating Scale, and the Ways of Coping Checklist–Revised. The results indicate that a positive correlation exists between the stress level of a life event and the degree to which that event integrates into the possible‐selves repertoire. A life event that demonstrates a high degree of integration results in a positive impact on coping. This study paves the way for prevention programs aimed at promoting an individual's well‐being while facing challenging life events across adulthood.     

Long-term adverse health outcomes of physical workplace violence: a 7-year population-based follow-up study

The aim of the present study was to analyse whether physical workplace violence increases the risk of long-term adverse health outcomes (i.e., high number of visits to the general practitioner, outpatient treatment, hospital admittance, antidepressant use, and/or having a mental disorder). The study was based on representative survey data from 2006 and 2010 (entitled “How are you?”) merged with register data for a 7-year follow-up period (N = 30,812). To examine if physical workplace violence was a predictor of adverse health outcomes, logistic regression models were conducted for the total follow-up period and for each follow-up year with the different outcome measures as the dependent variables. In the follow-up period, individuals who were exposed to physical workplace violence had a higher number of visits to the general practitioner, had more often received outpatient treatment, and had more often been admitted to hospital than their non-exposed counterparts. Moreover, exposed individuals had higher odds of using antidepressants in the last three follow-up years than did non-exposed individuals. The findings call for heightened attention to securing preventive as well as rehabilitative strategies to help victims of physical workplace violence with the aim of avoiding adverse long-term health consequences.     

Use of positive interventions: Does neuroticism moderate the sustainability of their effects on happiness?

Previous research indicates that performing positive activities boosts happiness. The present studies examined whether neuroticism would moderate the sustainability of the effects of positive activities on happiness. Study 1 showed that the effects of counting blessings/kindness daily for seven days lasted a week after participants stopped performing the activity, but only for low-neuroticism individuals (who reported increased happiness) and not high-neuroticism individuals. However, a week post-intervention, gratitude-/kindness-listing participants were more likely to choose an amusing rather than a sad film, regardless of neuroticism differences. This suggests that behavioral choice is more sensitive to positive intervention effects than self-reported happiness. In Study 2, high-neuroticism individuals who occasionally visualized and wrote about their best possible selves over three weeks were happier than their counterparts in the control condition. The present research illustrates that although neuroticism moderates the sustainability of positive intervention effects, encouraging continuance of positive activities may produce more lasting effects.     

The effects of exercise withdrawal on mood and inflammatory cytokine responses in humans

Mechanisms underlying the relationship between exercise and mood are not well understood. This study sought to investigate the role of pro- and anti-inflammatory cytokines and autonomic balance in determining the impact of exercise withdrawal on negative mood. Healthy men and women who regularly exercised (N?=?26, mean age?=?25.5 years, SD?=?4.5 years) were randomised to exercise withdrawal or exercise maintenance for 2 weeks. Protocol adherence was monitored using accelerometers. Inflammatory markers from plasma (interleukin-6, IL-6; tumour necrosis factor-alpha; interleukin-10; and interleukin-1 receptor antagonist), heart-rate variability (HRV) and measures of mood (General Health Questionnaire-28 (GHQ) and the Profile of Mood States (POMS)) were assessed at study entry and at 2-week follow-up. Exercise withdrawal resulted in significant increases in negative mood over time on both the GHQ (p?=?0.028) and the POMS (p?=?0.005). Following the intervention, IL-6 concentration was lower in the exercise withdrawal than exercise maintenance condition (p?=?0.05). No intervention effects were observed for other cytokines or HRV. The mood changes were significantly related to changes in IL-6 concentration (β?=?-?0.50, p?=?0.011), indicating that reduction in IL-6 was related to increased negative mood. Our results are consistent with positive effects of exercise on mental health, but further research on inflammatory pathways is warranted.     

Defensive evaluation of antismoking messages among college-age smokers: the role of possible selves.

This study hypothesized that individuals respond to antismoking messages in a biased or defensive manner to the degree that smoking is a personally relevant activity for them. The authors operationalized the personal relevance of smoking variously as smoking behavior (smoking status, rate, duration, and recent attempts to quit), endorsement of the smoker stereotype, and importance of smoking behavior as an identity within the self-concept (current self and possible selves). In the experiment, smokers (n = 82) and nonsmokers (n = 105) privately viewed several antismoking video segments. Smoking status, current smoking identity, and long-term future smoking identity were significantly associated with a defensive evaluation of antismoking messages. The study concludes that the concept of possible selves (H. Markus & P. Nurius, 1986) is critical in understanding college-age smoking and in the design of effective antismoking campaigns.     

The effects of exercise on body satisfaction and affect

This research used ecological momentary assessment to examine the effects of exercise on state body dissatisfaction and affect in 33 undergraduate females with high trait body dissatisfaction and 28 with low trait body dissatisfaction who exercised at least three times weekly. Trait body dissatisfaction was investigated as a moderator of the effects of exercise as well as different motivations for exercise. Results indicated all participants experienced lower state body dissatisfaction and negative affect and greater positive affect post-exercise. Trait body dissatisfaction moderated the association between motivations and exercise effects. Appearance and weight motivations were related to higher state body dissatisfaction for all individuals. Fitness and health motivations were related to higher state body dissatisfaction for high trait body dissatisfied individuals and lower state body dissatisfaction for low trait body dissatisfied individuals. Thus, although exercise has positive effects on body dissatisfaction and affect for high frequency exercisers, their exercise motivations impact these effects.     

Continuity and Change in Possible Selves in Later Life: A 5-Year Longitudinal Study

This study explored how older adults' possible selves (i.e., images of the self in the future) are influenced by the passage of time. We investigated whether possible selves would display continuity or change, and whether balance exists in the possible selves repertoire (i.e., presence of a hoped-for and a feared self in the same domain). In addition, we examined the influence of psychosocial factors (i.e., health locus of control, life satisfaction). Findings show that both hoped and feared possible selves remain stable and balanced over time. When change was found it was generally emergent in nature, with domains becoming important over time. This was especially true for the domain of health. As the first reported longitudinal study of possible selves, this study highlights the developmental sensitivity of possible selves as a tool for understanding the age-related concerns of older adults.
