Dietary planning,self-efficacy,and outcome expectancies play a role in an online intervention on fruit and vegetable consumption

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (M_age = 41.2, SD_age = 11.45; range: 19–66 years) was conducted in Italy, Spain and Greece, followed up at three and six months, comparing a static with a dynamic, feedback-intensive platform.

Results: Linear mixed models yielded an increase in FV consumption in both the dynamic and the static intervention arms. In men, outcome expectancies were positively related to follow-up FV intake. Dietary planning interacted with self-efficacy on behavioural outcomes.

Conclusion: FV intake increased overall, and being a woman and involvement in planning facilitated behaviour change. Women seemed to be more engaged in the dynamic platform resulting in a higher amount of planning. Initial motivation, as indicated by outcome expectancies, seemed to be beneficial for men. Self-efficacious individuals benefitted from their engagement in planning, but self-efficacy did not compensate for failing to plan.     

Emotional intelligence, personality, and task-induced stress

Emotional intelligence (EI) may predict stress responses and coping strategies in a variety of applied settings. This study compares EI and the personality factors of the Five Factor Model (FFM) as predictors of task-induced stress responses. Participants (N = 200) were randomly assigned to 1 of 4 task conditions, 3 of which were designed to be stressful. Results confirmed that low EI was related to worry states and avoidance coping, even with the FFM statistically controlled. However, EI was not specifically related to task-induced changes in stress state. Results also confirmed that Neuroticism related to distress, worry, and emotion-focused coping, and Conscientiousness predicted use of task-focused coping. The applied utility of EI and personality measures is discussed.     

Tracking the mind during reading: the influence of past, present, and future words on fixation durations

Reading requires the orchestration of visual, attentional, language-related, and oculomotor processing constraints. This study replicates previous effects of frequency, predictability, and length of fixated words on fixation durations in natural reading and demonstrates new effects of these variables related to 144 sentences. Such evidence for distributed processing of words across fixation durations challenges psycholinguistic immediacy-of-processing and eye-mind assumptions. Most of the time the mind processes several words in parallel at different perceptual and cognitive levels. Eye movements can help to unravel these processes.     

Adoption and maintenance of physical activity: Planning interventions in young, middle-aged, and older adults

Young, middle-aged, and older adults in orthopaedic outpatient rehabilitation (N?=?373) were randomly assigned to either an interviewer-assisted or a standard-care self-administered planning intervention. Physical activity planning consisted of specifying action plans to facilitate action initiation, and coping plans to overcome barriers. The interviewer-assisted condition led to more complete action plans and a longer duration of physical activities up to six months after discharge. Regarding coping planning, older and middle-aged adults benefited more from interviewer-assisted planning while younger adults benefited more from self-administered planning. Planning as such was found to be an effective tool for enactment irrespective of chronological age. The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.     

Translating intentions into nutrition behaviors via planning requires self-efficacy: evidence from Thailand and Germany

A first step towards the improvement of daily dietary behaviors is forming an intention to change one's nutrition. However, an intention by itself is not sufficient for successful action. Rather, to translate intentions into behavior, careful planning is recommended. Thus, planning constitutes a mediator between the intention and the behavior. However, if a person lacks self-efficacy, this mediation might fail. Previous research in Costa Rica and South Korea has identified perceived self-efficacy as a moderator of the intention-planning-behavior relationship. To examine further the moderator role of self-efficacy, two additional studies were designed in Thailand and Germany. Study 1 surveyed 1718 Thai university students in terms of a low-fat diet; Study 2 surveyed 1140 German internet users in terms of their fruit and vegetable consumption at two measurement points in time, 6 months apart. Intentions served as predictor, planning as mediator, self-efficacy as moderator, and behaviors as outcomes. First, intentions were translated into nutrition behaviors by planning. Second, self-efficacy moderated this mediation in both studies: The strength of the mediated effect increased along with levels of self-efficacy, even when accounting for baseline behaviors. For planning to mediate the intention-behavior relation, people must not harbor self-doubts. If they lack self-efficacy, intentions are not well translated into nutrition behavior through planning.     

Planning and Self-Efficacy in the Adoption and Maintenance of Breast Self-Examination: A Longitudinal Study on Self-Regulatory Cognitions

Many women may be reluctant to perform breast self-examination (B.S.E.) regularly due to motivational or self-regulatory deficits. The Health Action Process Approach (Schwarzer, R. (1992). Self-efficacy in the adoption and maintenance of health behaviors: theoretical approaches and a new model. In: Schwarzer, R. (Ed.), Self-efficacy: Thought Control of Action , pp. 217-243. Hemisphere, Washington DC; Schwarzer, R. (2001). Social-cognitive factors in changing health-related behavior. Current Directions in Psychological Science , 10 , 47-51.), a health behavior change model that advocates the separation of motivation and action phases, such as goal setting and goal pursuit, was applied to data from 418 young women whose risk perceptions, outcome expectancies, self-efficacy, intention to perform B.S.E., planning, and reported examination behaviors were examined at two points in time. Risk perception was found to have a negligible influence in a path analysis, whereas self-efficacy emerged as the best predictor of intention and planning. Planning, in turn, appeared to be the best predictor of B.S.E. behaviors, followed by self-efficacy. The results point to the influential role that self-regulatory strategies (such as planning) play in translating goals into action. The study contributes to the current debate on stage theories of health behavior change and the orchestration of self-beliefs and strategies in the context of goal-directed behaviors.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.     

Environmental anxiety: Assessing emotional distress and concerns after toxin exposure

Abstract

Anxiety in face of environmental risks is common, but few attempts have been made to assess individual differences psychometrically and to validate the measures in samples that have suffered from exposure to neurotoxic substances. The present study deals with this problem in two ways. First, levels of general anxiety were determined in two large independent samples of workers who were exposed to multiple organic solvents and in their nonexposed referents. In both samples, anxiety was substantially higher in exposed subjects than in their referents. Second, an Environmental Worry Scale (EWS) was developed and validated in three samples. This 17-item instrument and its 8-item subscale yielded satisfactory psychometric properties and also succeeded in discriminating solvent exposed from nonexposed subjects. Finally, the EWS was used in a structural equation model that was designed to predict the intention to avoid chemicals. The worry factor served as a mediator between exposure and intention, whereas exposure by itself did not influence intentions.     

Activity experiences shape perceived fitness trajectories: Results from a 6-month randomized controlled trial in older women

ABSTRACT

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70–93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities.
