There is a growing number of eHealth interventionsaiming at enhancing lifestyle to address obesity. However, theexisting interventions do not take the emotional aspects ofobesity into account. Forty percent of the overweight populationis an emotional eater. Emotional eaters gain weight because ofpoor emotion regulation, not just due to bad eating habits. Weaim at developing a personalised virtual coach ‘Denk je zèlf!’providing support for self-regulation of emotions for obeseemotional eaters. This paper presents a research study protocolon validating persuasive coaching strategies in emotionregulation, based on Dialectical Behaviour Therapy, ultimatelytargeting behaviour change. Our goal is to design a personalisedeCoaching framework, allowing us to optimally translatesuccessful behaviour change mechanisms and techniques, suchas dialectical strategies, into personalised persuasive coachingstrategies.

Background: Around 13% of the world’s population suffers from obesity. More than 40% of people with obesity display emotional eating behaviour (eating in response to negative emotions or distress). It is an alternate to moreeffective coping strategies for negative emotions. Our study explored the opportunities for helping adults with emotional overeating using a virtual coach, aiming to identify preferences for tailored coaching strategies applicable in a personal virtual coach environment. Three different coaching strategies were tested: a validating, a focus-on-change, and a dialectical one – the latter being a synthesis of the first two strategies. Methods: A qualitative study used vignettes reflecting the two most relevant situations for people with emotional eating: 1. experiencing negative emotions, with ensuing food cravings; and 2. after losing control to emotional eating, with ensuing feelings of low self-esteem. Applied design: 2 situations × 3 coaching strategies. Participants: 71 adult women (Mage 44.4/years, range 19–70, SD = 12.86) with high scores on the DEBQ-emotional eating scale (Memo 3.65, range 1.69–4.92, SD = .69) with mean BMI 30.1 (range 18–46, SD = 6.53). They were recruited via dieticians’ practices, were randomly assigned to the conditions and asked how they would face and react to thepresented coaching strategies. Data were transcribed and a thematic analysis was conducted. Results: Qualitative results showed that participants valued both the validating coaching strategy and the focus-onchange strategy, but indicated that a combination of validation and focus-on-change provides both mental supportand practical advice. Data showed that participants differed in their level of awareness of the role that emotions play in their overeating and the need for emotion-regulation skills. Conclusion: The design of the virtual coach should be based on dialectical coaching strategies as preferred by participants with emotional eating behaviour. It should be tailored to the different stages of awareness of their emotions and individual emotion-regulation skills.

Objectives: Emotional eating is recognized as a potential contributor to weight gain. Emotional eaters often hide their problems because of feelings of shame about their behavior, making it challenging to provide them with the necessary support. The introduction of a virtual coach might offer a potential solution in assisting them. To find out whether emotional eaters are receptive to online personalized coaching, we presented emotional eaters with two essential proto-typical problem situations for emotional eaters: “experiencing cravings” and “after giving in to cravings,” and asked them whether they preferred one of the three coaching strategies presented: Validating, Focus-on-Change and Dialectical.Methods: An experimental vignette study (2 × 3 design) was carried out. The vignettes featured two distinct personas, each representing one of the two common problem scenarios experienced by emotional eaters, along with three distinct coaching strategies for each scenario. To identify potential predictors for recognition of problem situations, questionnaires on emotional eating (DEBQ), personality traits (Big-5), well-being (PANAS), and BMI were administrated.Results: A total of 62% of the respondents identified themselves with “after giving in to cravings” and 47% with “experiencing cravings.” BMI, emotional eating and emotional stability appeared to be predictors in recognizing both the problem situations. In “experiencing cravings,” the participating women preferred Dialectical and the Validation coaching strategies. In the “after giving in to cravings” condition, they revealed a preference for the Dialectical and the Focus-on-Change coaching strategies.Conclusion: Using vignettes allowed a less threatening way of bringing up sensitive topics for emotional eaters. The personas representing the problem situations were reasonably well recognized. To further enhance this recognition, it is important for the design and content of the personas to be even more closely related to the typical problem scenarios of emotional eaters, rather than focusing on physical characteristics or social backgrounds. This way, users may be less distracted by these factors. With the knowledge gained about the predictors that may influence recognition of the problem situations, design for coaching can be more customized. The participants represented individuals with high emotional eating levels, enhancing external validity.

Obesity has become a major societal problem worldwide [1][2]. The main reason for severe overweight is excessive intake of energy, in relation to the individual needs of a human body. Obesity is associated with poor eating habits and/or a sedentary lifestyle. A significant part of the obese population (40%) belongs to a vulnerable target group of emotional eaters, who overeat due to negative emotions [3]. There is a need for self-management support and personalized coaching to enhance emotional eaters in recognising and self-regulating their emotions.Over the last years, coaching systems have been developed for behavior change support, healthy lifestyle, and physical activity support [4]-[9]. Existing virtual coach applications lack systematic evaluation of coaching strategies and usually function as (tele-)monitoring systems. They are limited to giving general feedback to the user on achieved goals and/or accomplished (online) assignments.Dialectical Behavior Therapy (DBT) focuses on getting more control over one’s ownemotions by reinforcing skills in mindfulness, emotion regulation, and stress tolerance [10]. Emotion regulation is about recognizing and acknowledging emotions and accepting the fact that they come and go. The behavior change strategies within DBT are based on validation and dialectics [11]. Dialectics changes the users’ attitude and behavior by creating incongruence between an attitude and behavior since stimuli or the given information contradict with each other.The ultimate goal of the virtual coach is to raise awareness of emotional eaters on their own emotions, and to enhance a positive change of attitude towards accepting the negative emotions they experience. This should result in a decrease of overeating and giving in to binges. We believe that the integration of the dialectical behavior change strategies and persuasive features from the Persuasive System Design Model by Kukkonen and Harjumaa [12] will enhance the personalization of the virtual coach for this vulnerable group. We aim at developing a personalized virtual coach ‘Denk je zèlf!’ (Dutch for ‘Develop a wise mind and counsel yourself’) providing support for self-regulation of emotions for young obese emotional eaters. This poster presents an eCoaching model and a research study protocol aiming at the validation of persuasive coaching strategies based on behavior change techniques using dialectical strategies. Based on the context (e.g., location), emotional state of the user, and natural language processing, the virtual coach application enables tailoring of the real-time feedback to the individual user. Virtual coach application communicates with the user over a chat timeline and provides personal feedback.The research protocol decribes the two weeks field study on validating persuasive coaching strategies for emotional eaters. Participants (N=30), recruited via a Dutch franchise organization of dietitian nutritionists, specialized in treating emotional eating behaviors, will voluntarily participate in this research study. Participants will be presented with short dialogues (existing questions and answers) and will be asked to select the preferred coaching strategy (validating or a dialectical), according to their (current) emotions. To trigger a certain emotion (e.g., the affect that fits best with the chosen coaching strategy), a set of pictures will be shown to the user that evoke respectively sadness, anger, fear, and disgust [13].Participants will be asked to fill out the demographics data ((nick) name, age, gender, weight, length, place of residence) and three questionnaires: • Dutch Eating Behavior Questionnaire (DEBQ) [14],• Five Factor Personality Inventory (FFPI) [15], • Quality of Life Index Questionnaire [16].This research study aims at answering the following research questions: “Which coaching strategies do users with a specific type of emotional eating behavior benefit most from while consulting their personalized virtual coach?; “Which coaching strategies are optimal for which emotions?” and “Which coaching approach do users prefer in which context, e.g. time of the day, before/after a craving?”

The first year of study is very exciting for many students. Everything is new: the school, your schedule, the teachers, and your fellow students. How can a university ensure a smooth transition for first-year students? For this, Inholland launched the Students for Students (S4S) project in the 2019-2020 academic year. In this project, second-year students (studentcoaches) support first-year students with their studies. They do this based on their own experience and the training they receive during their year as studentcoaches. Research shows that peer-mentoring is very successful in aiding first-year students through their first year of the study program. Peer-mentoring has the potential to increase well-being, social bonding, the feeling of belonging, and student resilience. It also ensures smoother academic integration, as peer-mentoring focuses on developing academic skills as well. Additionally, a studentcoach is often a low threshold point of contact for students where they can go with questions.

Just what and how eight experienced teachers in four coaching dyads learned during a 1-year reciprocal peer coaching trajectory was examined in the present study. The learning processes were mapped by providing a detailed description of reported learning activities, reported learning outcomes, and the relations between these two. The sequences of learning activities associated with a particular type of learning outcome were next selected, coded, and analyzed using a variety of quantitative methods. The different activity sequences undertaken by the teachers during a reciprocal peer coaching trajectory were found to trigger different aspects of their professional development.

Background:More than 40% of the obese population suffer from emotional eating behaviour. They give in to overeating, because they lack effective coping strategies for negative emotions. Our studies explored the opportunities for helping emotional eaters with a virtual coach. Therefore the objective of this study was to identify preferences for coaching strategies for emotional eaters applicable in a personal virtual coach environment. Three different coaching strategies were tested: a validating, a focus-on-change, and a dialectical.Methods:Instruments: Vignettes, reflecting two most relevant situations for emotional eaters: 1. having food cravings experiencing negative emotions. 2. having given into overeating experiencing feelings of low self-esteem; DEBQ.Applied Design: 2 situations x 3 coaching strategies. Participants: 71 female emotional eaters (age mean 44, range 19-70) with high scores on the DEBQ (mean 3,6) with eventual overweight (mean BMI 30,2, range 18-45); recruited via dietist practices), were randomly assigned to the conditions and were asked how they would encounter and react to the presented coaching strategies. Data is obtained by thematic analyses.Findings:Qualitative results showed that emotional eaters clearly preferred dialectical coaching in both conditions. Although this preference is expressed for craving and overeating situations, the other coaching strategies were differently evaluated for both conditions. Our study showed emotional eaters have not only differences in preferences for coaching strategies, they are in different stages of knowledge about emotion regulation.Discussion:Design of the virtual coach should be based on integration of the validation and focus-on-change into dialectical coaching strategies as preferred by emotional eaters and has to tailor to the different stages of self-knowledge about emotion regulation.

Living a sedentary lifestyle is one of the major causes of numerous health problems. To encourage employees to lead a less sedentary life, the Hanze University started a health promotion program. One of the interventions in the program was the use of an activity tracker to record participants' daily step count. The daily step count served as input for a fortnightly coaching session. In this paper, we investigate the possibility of automating part of the coaching procedure on physical activity by providing personalized feedback throughout the day on a participant's progress in achieving a personal step goal. The gathered step count data was used to train eight different machine learning algorithms to make hourly estimations of the probability of achieving a personalized, daily steps threshold. In 80% of the individual cases, the Random Forest algorithm was the best performing algorithm (mean accuracy = 0.93, range = 0.88–0.99, and mean F1-score = 0.90, range = 0.87–0.94). To demonstrate the practical usefulness of these models, we developed a proof-of-concept Web application that provides personalized feedback about whether a participant is expected to reach his or her daily threshold. We argue that the use of machine learning could become an invaluable asset in the process of automated personalized coaching. The individualized algorithms allow for predicting physical activity during the day and provides the possibility to intervene in time.

In this article, the outcomes of a survey aimed to investigate how aware of and how capable coaches in higher vocational Dutch education perceive themselves to assist students displaying mental health and well-being issues are presented. Additionally, the article explores coaches’ perceptions regarding the frequency, form of help offered, topics to be tackled and the preferred form in which this help should be provided. The author conducted a survey that gathered qualitative and quantitative data from coaches (N 5 82) at a Dutch University of Applied Sciences in the north of the Netherlands. A differentiation in coaches’ number of years of teaching and coaching experience was considered.

Acknowledging the knowledge gaps and novel paradigms outlined above within both coaching research and practice, the PhD research aims to investigate how need-supportive coaching—rooted in Self-Determination Theory (SDT)—effectively fulfils the satisfaction of beginning teachers’ basic psychological needs (BPNs) and autonomous motivation in pursuing their coaching goals within dyadic coaching relationships. To systematically explore this overarching objective, this PhD project and thesis adopt a structured, four-step approach, where each step investigates specific and complementary aspects of the coaching process. Collectively, these steps provide a comprehensive examination of how and under what conditions BPN-supportive coaching facilitates optimal motivational outcomes, enriching our understanding of the dynamic processes that shape coaching effectiveness among beginning teachers. Specifically, four research questions systematically guide the four research steps:1. What is the current state of empirical evidence linking BPN support, BPN satisfaction, and autonomous motivation within coach-coachee relationships?2. How do perceptual distances between coaches’ and coachees’ perceptions regarding BPN support relate to the coachees’ BPN satisfaction?3. How do coaches’ and coachees’ BPN satisfaction mutually predict autonomous motivation toward shared goals in their dyadic relationships?4. How do coaches and coachees dynamically co-regulate BPN interactions in real-time dyadic coaching conversations?Chapter 1 outlined a four-step empirical approach across Chapters 2 to 5 to understand BPN-supportive coaching. Chapter 2 meta-analysed the extant literature guided by a circular framework connecting BPN support, BPN satisfaction, and autonomous motivation for both parties. The results revealed that previous studies predominantly used individual-level data, neglecting the dynamic, reciprocal interactions in coaching. Chapter 3 investigated perceptual distance between coaches and coachees regarding BPN support using polynomial regression and response surface analysis. Results indicated that coachees reported greater BPN satisfaction when perceptions were closely aligned. Chapter 4 adopted the Actor-Partner Interdependence Model to examine how both parties’ BPN satisfaction is associated with their own and each other’s autonomous motivation. We found a positive unidirectional association between coachees’ relatedness satisfaction and coaches’ autonomous motivation and bidirectional associations for autonomy satisfaction. Chapter 5 employed State Space Grid analyses to capture the moment-to-moment co-regulation of autonomy in coach-coachee dyads. Results revealed recurrent patterns of predominant functional co-regulation (e.g., autonomy support met with proactive autonomy expression), and occasional dysfunctional co-regulation (e.g., evaluative feedback met with disengagement). Temporal evolvement in autonomy co-regulation was identified across coaching sessions in response to changing goals. Chapter 6 synthesised the contributions of the thesis. Collectively, BPN-supportive coaching can be viewed as a context-sensitive, interdependent, co-regulatory, and dynamic process, and we provided guidance for adaptive and relationally grounded coaching practices.
