The contribution and interplay of implicit and explicit processes on physical activity behavior: empirical testing of the physical activity adoption and maintenance (PAAM) model.

The adoption and maintenance of physical activity (PA) is an important health behavior. This paper presents the first comprehensive empirical test of the Physical Activity Adoption and Maintenance (PAAM) model, which proposes that a combination of explicit (e.g., intention) and implicit (e.g., habit,, affect) self-regulatory processes is involved in PA adoption and maintenance. Data were collected via online questionnaires in English, German, and Italian at two measurement points four weeks apart. The study included 422 participants (Mage= 25.3, SDage= 10.1; 74.2% women) from Germany, Switzerland, Italy, Canada, and the U.S. The study results largely supported the assumptions of the PAAM model, indicating that intentions and habits significantly mediate the effects of past PA on future PA. In addition, the effect of past PA on future PA was shown to be significant through a mediation chain involving affect and habit. Although the hypothesis that trait self-regulation moderates the intention-behavior relationship was not supported, a significant moderating effect of affect on the same relationship was observed. The results suggest that interventions targeting both explicit and implicit processes may be effective in promoting PA adoption and maintenance.

WiN-Reha-effectiveness and durability of effects of orthopedic rehabilitation programs and the study of psychological determinants of aftercare behaviors: a study protocol.

Background and aim: Rehabilitation programs have been shown to have a positive impact on patients' health and work ability. However, the durability of these effects and the extent to which patients alter their health behaviors remain underexplored. This study is divided into two parts; the first assesses the effectivity of rehabilitation programs for orthopedic patients and the durability of effects. The second part examines psychological determinants of aftercare health behaviors. Subject and methods: Study Part 1 employs a longitudinal study design with up to nine measurement occasions encompassing a three-year follow-up period. Treatment is provided as per orthopedic indications through rehabilitation centers. Measures include subjective health, work ability, body weight, and physical activity behavior. Study Part 2 incorporates a mixed-methods design, involving both quantitative and qualitative assessments. The quantitative component aims to recruit a subsample from Study Part 1 to assess psychological determinants of aftercare health behaviors over 12 to 24 weeks using Ambulatory Assessment. The qualitative component aims to explore the reasons for maintenance and discontinuation of health behaviors and involves a reflexive thematic analysis of interviews with at least 16 individuals, analyzing the differences between those who adopt and those who discontinue their aftercare health behavior. Discussion: This comprehensive research project may offer insights into the long-term effectivity of rehabilitation programs. Furthermore, it may foster a more profound understanding of the successful incorporation of health-promoting aftercare behaviors, such as physical activity, into everyday life. Therefore, this study may contribute significantly to the evolving field of patient-centered rehabilitation. Trial registration: The trial has been registered at the German Register of Clinical Studies (DRKS) with the registration number: DRKS00032257.

Impact of digital and conventional rehabilitation aftercare on physical and mental health in orthopedic patients in Germany.

The integration of digital interventions in health rehabilitation offers promising opportunities to improve patient outcomes. However, empirical studies comparing the effectiveness of digital and traditional rehabilitation interventions remain scarce. This study was designed to evaluate the impact of a digital aftercare program, compared to traditional aftercare and a control group, on both psychological and physical health outcomes in individuals undergoing orthopedic rehabilitation. Additionally, the study also aimed to examine the moderating effects of age and gender. The study employed a partially controlled trial design, engaging a cohort of 805 orthopedic patients, divided into: digIRENA (n = 323, digital aftercare), IRENA (n = 252, traditional aftercare), and a control group (n = 230, without organized aftercare). Measurements took place at four different time points: baseline (start of the rehabilitation program), T1 (13 weeks after the start of rehabilitation, marking the midpoint of aftercare), T2 (26 weeks, marking the end of aftercare), and T3 (43 weeks, to assess the sustainability of aftercare effects). The SF-12 Health Survey was the primary data collection instrument for measuring trends in physical and mental health outcomes over these intervals using repeated measures ANOVA. The results show that rehabilitants in the digIRENA group participated for a longer period of time than rehabilitants in the IRENA group, while the two groups did not differ in terms of motivation at T0 and organized physical activity outside of aftercare at T3. A significant improvement in physical health outcomes was observed in all groups across time, with digIRENA participants showing the greatest improvement. For mental health, all groups showed initial improvements, with the digIRENA group showing the most pronounced increase at T2. Overall, there was a decline in the effects achieved 4 months after the end of aftercare. When age and gender were included as covariates, the time effect for mental health disappeared, showing a significant time * gender interaction due to significantly lower baseline scores of women compared to men. The results of the study show that digital interventions, in particular the digIRENA program, contribute to improving health rehabilitation outcomes. The digIRENA program and similar digital health interventions may offer potential for improving health rehabilitation aftercare.

Exploring proportions of spontaneous and goal-directed self-talk - It is not always the one or the other.

The dichotomous classification of self-talk statements into goal-directed as a more controlled type of self-talk and spontaneous as a more uncontrolled type of self-talk might be an oversimplification. To address this issue, two studies were conducted aiming to explore the idea that the distinction between the two self-talk types should rather be proportional and not mutually exclusive. In Study 1, football players took part in a penalty competition and were subsequently asked to state the self-talk they had before and after the penalty. In Study 2, table tennis players took part in two activities (i.e., a precision task and a competitive set) and were subsequently asked to state the self-talk they had before the individual rounds in each activity. In both studies, the players subsequently rated for each self-talk statement the extent to which it was spontaneous and the extent to which it was goal-directed. The majority of self-talk statements were rated to some extent as both spontaneous and goal-directed. For Study 1, paired-sample t-tests showed that before a penalty kick self-talk was more goal-directed than spontaneous and after the penalty kick it was more spontaneous than goal-directed. In the more exploratory Study 2, multilevel regression analyses showed that the two types of self-talk could not predict sports performance. While the results support the usefulness of the distinction between spontaneous and goal-directed self-talk, treating the two types of self-talk as proportional rather than dichotomous might reflect more accurately the mental activity. Key words: dual-process, organic self-talk, self-regulation, System 1, System 2.

Examining the relation between emotional experiences and emotional expressions in competitive tennis matches.

Introduction: Emotions consist of different components such as the emotional experience, physiological reactions, action tendencies, or emotional expressions. Assessing the relation of these components may help to better understand the role of emotions in sport competitions. Based on the component process model of emotions, the goal of the present study was to assess the relation between emotional experiences and emotional expressions. Methods: Twenty tennis players (7 female) with an average age of 23.10 (SD = 4.88) were taped during competitive tennis matches. Thereafter, in individual meetings, after having watched themselves on the footage at pre-selected points, the players had to indicate whether, immediately after the end of a rally, they had a positive or a negative emotional experience and, in case they had one, rate its intensity. Moreover, based on their observable behavior, the players were also asked to state whether they could recognize a positive or a negative emotional expression and, in case they recognized one, rate its intensity. The occurrence of emotional expressions was additionally rated by two external coders. Using multilevel models, separate analyses were conducted for positive emotions after won points and negative emotions after lost points. Results and discussion: For both positive and negative emotions, the results indicated a positive correlation between emotional experiences and emotional expressions. Moreover, the intensity of emotional experiences could predict the occurrence of an emotional expression rated by both the players or external coders. These insights into the relation between emotional experiences and emotional expressions may help players to more effectively regulate their emotions.
