Exercise and the experience and appraisal of daily stressors: a naturalistic study

Thirty-eight men and 35 women completed diaries of exercise, mood, and the experience and appraisal of daily stressors over 12 consecutive days. It was hypothesized that exercise would be associated with positive moods and with the experience of fewer daily stressors. Positive moods were rated higher and depression lower on exercise days than no-exercise days. Participants low in trait anxiety reported fewer stressful events on the days on which they exercised. Those with strong personal (health, physical appearance, and mood) motives for exercise reported more stressful daily events overall; in addition, they experienced more potentially stressful events as nonstressful on the days during which they engaged in physical exercise. The results are discussed in relation to the acute after-effects of exercise on mood and stress responsivity and the long term of psychological benefits of regular exercise.     

A Cross-Cultural Investigation of Cognitions and Depressive Symptoms in Adolescents.

Adolescents (N=2,272) from Hong Kong and the United States provided information regarding their depressive symptoms, cognitions (self-efficacy, negative cognitive errors, and hopelessness), and stressful events between 2 surveys 6 months apart. Depressive symptoms and hopelessness were higher, and self-efficacy and negative cognitive errors were lower in Hong Kong than in the United Stales. Cognitions were associated with concurrent depressive symptoms and predicted depressive symptoms 6 months later in both cultures. The "reverse" model was also supported with more variance predicted by depressive symptoms to later cognitions than from cognitions to depressive symptoms. There was some support for the hypothesis that self-efficacy is less salient in collective compared with individualistic cultures. These findings extend cognitive theories of depression to a non-Western culture. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Growth trajectories of exercise self-efficacy in older adults: Influence of measures and initial status.

Objective: This study examined differential trajectories of exercise-related self-efficacy beliefs across a 12-month randomized controlled exercise trial. Method: Previously inactive older adults (N = 144; M age = 66.5) were randomly assigned to one of two exercise conditions (walking, flexibility-toning-balance) and completed measures of barriers self-efficacy (BARSE), exercise self-efficacy (EXSE), and self-efficacy for walking (SEW) across a 12-month period. Changes in efficacy were examined according to efficacy type and interindividual differences. Latent growth curve modeling was employed to (a) examine average levels and change in each type of efficacy for the collapsed sample and by intervention condition and (b) explore subpopulations (i.e., latent classes) within the sample that differ in their baseline efficacy and trajectory. Results: Analyses revealed two negative trends in BARSE and EXSE at predicted transition points, in addition to a positive linear trend in SEW. Two subgroups with unique baseline efficacy and trajectory profiles were also identified. Conclusion: These results shed new light on the relationship between exercise and self-efficacy in older adults. They also highlight the need for strategies for increasing and maintaining efficacy within interventions, namely targeting participants who start with a disadvantage (lower efficacy) and integrating efficacy-boosting strategies for all participants prior to program end.

Contextual correlates of adolescents' self-efficacy after smoking cessation.

Recent research has shown that daily changes in self-efficacy predict lapses and relapse into smoking after quitting among adolescent daily smokers, but it is not known if and how momentary self-efficacy is associated with affect-motivational states and external contexts. In the present study, 134 adolescent daily smokers were monitored daily during 1 week prior to and 3 weeks after they began their quit attempt. Participants completed questions on smoking, self-efficacy, affect-motivational states (craving and negative affect), and external contexts (seeing others smoke, experiencing a stressful event, and alcohol and coffee consumption) three times a day. Affect-motivational states as well as all external contexts (except for coffee consumption) were associated with lower self-efficacy when participants were still abstinent, but also after they had lapsed. Associations between the situational contexts and self-efficacy did not largely depend on individual characteristics such as baseline self-efficacy and age. Among girls, however, the negative associations between self-efficacy and negative affect and drinking alcohol were found to be stronger. These results show that adolescents' self-efficacy during a quit attempt may be responsive to affect-motivational states and external contexts, both before and after lapsing.

The impact of working life on health behavior: The effect of job strain on the cognitive predictors of exercise.

The theory of planned behavior (TPB) and R. A. Karasek's (1979) job strain model were used to investigate the predictors of exercise in a group of employees. A total of 241 employees completed an initial questionnaire; 1 week later 213 employees responded to a questionnaire measuring behavior. Employees in high-strain jobs did significantly less exercise than those in low-strain jobs, although they did not intend to do less, suggesting that work may impede the intention implementation. Intenders who failed to exercise had significantly higher work demands and lower exercise self-efficacy than intenders who succeeded in exercising. Work also affected exercise indirectly through self-efficacy. Thus, work may be a target for behavior change intervention because of its impact at 2 stages of the TPB.

Common and specific process factors in cardiac rehabilitation: Independent and interactive effects of the working alliance and self-efficacy.

Objective: Therapeutic processes in cardiac rehabilitation programs are virtually unexamined. Models were tested by which changes in the working alliance between patient and staff (agreement on goals/tasks; emotional bond) may affect outcomes in conjunction with changes in patient self-efficacy to change their diets and increase exercise. Design: Cardiac patients (n = 79) participated in a 12-week program, and completed assessments at early, mid, and late treatment. Main Outcome Measures: Changes in cardiac depression, physical health, perceived exertion during exercise, rate/pressure product at submaximal exercise tolerance, weight loss, return to work, total fat intake. Results: Early-treatment changes in agreement on goals/tasks were related to changes in psychosocial factors and perceived exertion during exercise independent of effects of changes in self-efficacy. Early-treatment changes in goals/tasks and self-efficacy interacted to predict changes in cardiorespiratory fitness, weight loss, and return to work such that patients high on both goals/tasks and self-efficacy showed the most gains. Conclusion: Sound therapeutic relationships between patients and staff may play an important role in facilitating the achievement of a wide-range of salutary outcomes during cardiac rehabilitation.

The effects of behavioural outcome goals, learning goals, and urging people to do their best on an individual's teamwork behaviour in a group problem-solving task.

States that research has shown that learning goals are superior to outcome goals on complex tasks. The effectiveness of behavioral outcome goals (set using behavioral observation scales), learning goals, and urging people to do their best was examined in the context of a training program designed to improve an individual's teamwork behavior in a group problem-solving task. 50 participants (mean age 25.3 yrs) who set behavioral or learning goals had higher self-efficacy relative to those urged to "do their best". Self-efficacy correlated positively with teamwork behavior and goal commitment. Behavioral goals were superior to learning goals and being urged to "do your best" in bringing about teamwork behavior. These findings suggest that behavioral outcome goals may mitigate the need for learning goals on complex tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predicting performance under acute stress: The role of individual characteristics.

This prospective study examined how differences in coping style, coping self-efficacy, and metacognitive awareness influence coping behavior and performance during a realistic acute stressful exercise in 2 military samples (n = 122 and n = 132). Results showed that coping self-efficacy and coping style affected coping behavior, and that, in turn, coping behavior affected performance. The findings of a post hoc analysis suggested that metacognitive awareness had an indirect relationship with coping behavior, through task-focused coping style and coping self-efficacy, instead of a predicted direct relationship. Together, these results indicate that coping style and coping self-efficacy are important predictors of performance under acute stress, and that this effect is mediated by coping behavior.

Timing of dietary change in response to a telephone counseling intervention: Evidence from the WHEL study.

Objective: Little is known about temporal patterns of diet change within interventions, nor about predictors of early and sustained successful change. Social-cognitive theory asserts that early successes in achieving behavior change increase self-efficacy, leading to longer-term success. Design: The authors conducted exploratory cluster analyses using dietary data from the first month of the telephone counseling intervention of the Women's Healthy Eating and Living (WHEL) Study. Main Outcome Measure: Change in dietary pattern at three early intervention timepoints. Results: Three clusters were identified: Cluster 1 (25%) was close to meeting study goals at baseline, but still made major changes; Cluster 2 (49%) and Cluster 3 (26%) were not achieving study goals at baseline, but Cluster 2 made substantial immediate changes, while Cluster 3 changed their diet more gradually. Baseline demographic and behavioral variables were associated with cluster membership; however, the strongest predictors of cluster were self-efficacy, motivation, and approaches to study goals. Cluster membership predicted dietary pattern at 12 months. Conclusion: These data suggest that a one-on-one telephone counseling intervention that is intensive in the early weeks may maximize the level of change achieved in a study.

Effects of exercising before versus after eating on dieting and exercise evaluations: A preliminary investigation.

Psychological processes may play a role in the evaluation of the effectiveness of exercise and subsequent food intake. In order to further investigate this phenomenon, the effects of the timing of exercise relative to an eating opportunity were evaluated. Female undergraduate participants who were of average weight and did not exercise regularly were randomly assigned to one of three conditions (exercise before eating [n = 10], exercise after eating [n = 11], or no exercise [n = 12]). Expectations of the effectiveness of the exercise, value of dieting, and intake were assessed. Participants who exercised after eating had higher expectations of the effectiveness of the exercise than those who exercised before eating, while those who exercised before eating reported valuing dieting more than controls. No effects on intake emerged; therefore, there appears to be a disconnect between dieting appraisals and actual eating behaviour. The results are discussed in relation to theories on conflicting goals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Walking to meet health guidelines: The effect of prompting frequency and prompt structure.

This study assessed the effects of frequency of prompting (phone calls once a week versus once every 3 weeks) and structure of prompting (high versus low structure) in 135 participants (132 women and 3 men) in a walking program designed to meet the American College of Sports Medicine's cardiovascular exercise goals. Survival analysis using 6 months of data points and using the criteria of walking at least 20 min a day for at least 3 times per week indicated an effect for more frequent versus less frequent prompting (46% and 13%) but not for high- versus low-structure prompting (30% and 31%). The results suggested the efficacy of frequent prompting delivered in inexpensive ways as a means to increase exercise adherence and the further parametric study of other basic behavior change strategies.

Expectancy-value constructs and expectancy violation as predictors of exercise adherence in previously sedentary women.

This prospective study examined effects of expectancy of exercise benefits, value of benefits, expectancy violation, and self-efficacy (SE) on exercise behavior and study dropout in sedentary women (n?=?86). SE predicted exercise for study completers but did not predict study dropout. After 6 and 12 weeks, participants evidenced expectancy violations, particularly for fitness and weight. Initial value, expectancy, and Expectancy?×? Value did not predict exercise for study completers, but dropouts had higher initial positive expectancies than did completers. Expectancy violations produced in Weeks 1–6 did not predict exercise in Weeks 7–12 in study completers, but dropouts in Weeks 7–12 had higher expectancy violations for weight in Weeks 1–6 than did completers. Follow-up revealed that study dropouts stopped exercising. Identifying individuals with high initial expectancies and expectancy violations may improve health behavior intervention and research.

Manipulating self-efficacy in the exercise environment in women: Influences on affective responses.

Self-efficacy was experimentally manipulated in an exercise context, and its effect on affective responses was examined. College women (N?=?46) were randomly assigned to a high- or low-efficacy condition, and efficacy expectations were manipulated by means of bogus feedback and graphs depicting contrived normative data. The manipulation successfully influenced affective responses, with participants in the high-efficacy group reporting more positive and less negative affect than did the low-efficacy group. Efficacy was significantly related to feeling-state responses during and after activity but only in the high-efficacy condition. The results suggest that self-efficacy can be manipulated and that these changes are related to the affective experience associated with exercise. Such findings may have important implications for the roles played by self-efficacy and affect in exercise adherence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory in posttraumatic stress disorder: Properties of voluntary and involuntary, traumatic and nontraumatic autobiographical memories in people with and without posttraumatic stress disorder symptoms.

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were made of memories of stressful events versus control events and involuntary versus voluntary memories in people high versus low in posttraumatic stress disorder (PTSD) symptom severity. For all participants, stressful memories had more emotional intensity, more frequent voluntary and involuntary retrieval, but not more fragmentation. For all memories, participants with greater PTSD symptom severity showed the same differences. Involuntary memories had more emotional intensity and less centrality to the life story than voluntary memories. Meeting the diagnostic criteria for traumatic events had no effect, but the emotional responses to events did. In 533 undergraduates, correlations among measures were replicated and the Negative Intensity factor of the Affect Intensity Measure correlated with PTSD symptom severity. No special trauma mechanisms were needed to account for the results, which are summarized by the autobiographical memory theory of PTSD.

Comparison of participatively set and assigned goals in the reduction of alcohol use.

The effects of setting goals on goal commitment, self-efficacy for goal achievement, and goal achievement in the context of an alcohol use intervention were examined using an experimental design in which participants were randomized to participatively set goals, assigned goals, and no goal conditions. One hundred and twenty-six heavy-drinking college students received a single cognitive-behavioral assessment/intervention session and completed measures of goal commitment, self-efficacy for goal achievement, and alcohol use. Results were consistent with, and expanded upon, previous research by demonstrating that having a goal for limiting alcohol consumption was predictive of lower quantity and frequency of alcohol use relative to not having a goal. Participation in goal setting yielded greater goal commitment and self-efficacy for goal achievement than assigned goals, but did not result in significantly greater reductions in alcohol use relative to assigned goals. Goal commitment and self-efficacy explained unique variance in the prediction of alcohol use at follow-up. Findings support the importance of goal setting in alcohol interventions and suggest areas for further research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does life satisfaction moderate the effects of stressful life events on psychopathological behavior during adolescence?

Psychologists within a positive psychology framework have proposed the existence of a set of psychological strengths that buffer against the development of psychopathology. To date, most research efforts in positive psychology have focused on adults. This longitudinal study tested the prediction that adolescents' judgments of life satisfaction moderate the influence of stressful life events on the subsequent development of psychopathological behavior. Using a sample of 816 middle and high school students, the study demonstrated support for the moderational model for externalizing behavior outcomes, but not internalizing behavior problems. Specifically, adolescents with positive life satisfaction (vs. those who were dissatisfied with their lives) were less likely to develop later externalizing behaviors in the face of stressful life events. The study also revealed that adolescent life satisfaction reports show moderate stability across a one-year time frame and independently predict subsequent externalizing behavior even while controlling for prior levels of externalizing behavior...

Sex differences in math performance: The role of children's approach to schoolwork.

This research examined whether the tendency for girls to outperform boys in the classroom is due to differences in how girls and boys approach schoolwork. In 5th grade and then again in 7th grade, children (N=518) reported on how they approach schoolwork (i.e., achievement goals and classroom behavior), their learning strategies, and their self-efficacy in math; math grades and achievement test scores were also collected. Girls were more likely than boys to hold mastery over performance goals and to refrain from disruptive classroom behavior, which predicted girls' greater effortful learning over time. The sex difference in learning strategies accounted for girls' edge over boys in terms of grades. Girls did not do better on achievement tests, possibly because self-efficacy, for which there was also no sex difference, was the central predictor of performance on achievement tests.

Physical activity after cardiac rehabilitation: Evidence that different types of self-efficacy are important in maintainers and relapsers.

Objective: To test whether maintenance self-efficacy predicts physical activity among individuals who maintain an active lifestyle and whether recovery self-efficacy predicts physical activity among those who relapse to a less active lifestyle. Study Design and Participants: In a longitudinal study, data were collected from 114 participants 4-10 days after a myocardial infarction (MI), 2 weeks after rehabilitation (2 months after MI), and 8 months after MI. Results: In a subgroup of participants who maintained regular activity at 8 months after MI, maintenance self-efficacy predicted physical activity. Among participants who had relapsed by 8 months after MI, recovery self-efficacy predicted physical activity. Conclusions: Those who conduct interventions among cardiac rehabilitation patients should aim to increase recovery self-efficacy among those patients who are at risk for relapse and to increase maintenance self-efficacy among those patients who are likely to maintain their level of physical activity.

Faith and unfaithfulness: Can praying for your partner reduce infidelity?

[Correction Notice: An erratum for this article was reported in Vol 99(4) of Journal of Personality and Social Psychology (see record 2010-20570-001). The article contained an error in Table 2, in the third column table heading. The correct table heading is provided in the erratum.] Because religion and/or spirituality is integral to the lives of a majority of the world population, we conducted 3 studies on the role of prayer in romantic relationships. Study 1 (N = 375) showed that prayer for the partner predicted lower levels of extradyadic romantic behavior over a 6-week period, over and beyond relationship satisfaction, and initial levels of extradyadic romantic behavior. In Study 2 (N = 83), we used an experimental design to show that participants assigned to pray for each day for 4 weeks engaged in lower levels of extradyadic romantic behavior during that time, compared with those who engaged in daily positive thoughts about the partner or a neutral activity. Perception of the relationship as sacred mediated the relation between experimentally manipulated prayer and later infidelity. Study 3 (N = 23) showed that objective observers rated participants who had been praying for their partner for 4 weeks as more committed to their romantic relationship than control participants. The implications of these results are then discussed.

The instability of health cognitions: Visceral states influence self-efficacy and related health beliefs.

Objective: To determine how visceral impulses, such as hunger and drug craving, influence health beliefs. Design: The authors assessed smokers' self-efficacy and intentions to quit while in a randomly assigned state of cigarette craving or noncraving (Study 1), and assessed dieters weight-loss beliefs while hungry or satiated (Study 2). Main outcome measures: Self-efficacy, smoking cessation, weight-loss goals. Results: The authors found, in both the context of smoking and weight-loss, that participants in a cold (e.g., satiated) state had different health beliefs than participants in a hot state (e.g., hungry). Specifically, in Study 1, the authors found that smokers who experienced cigarette craving had lower self-efficacy than did satiated smokers. Consequently, smokers who craved a cigarette had less intention to quit smoking in the future compared with satiated smokers. In Study 2, the authors found that hungry dieters had less self-efficacy than did satiated dieters. This difference led hungry dieters to form less ambitious future weight-loss goals and view prior weight-loss attempts with more satisfaction. Conclusion: These findings contribute to our understanding of the nature of health beliefs and reveal that health beliefs are more dynamic than previously assumed.
