Obesity is a fast-growing societal threat, causingchronic conditions, physical and psychological health problems,as well as sickness absence and heavy healthcare costs. Despitenumerous attempts to promote physical activity and healthydiet, existing interventions do not focus on the commonemotional causes of obesity. There is a need for self-managementsupport of this vulnerable target group: emotional eaters. Thispaper presents the results of the design case study focusing on aholistic design and evaluation of a personalised virtual mHealthcoach that provides self-management training ‘Denk je zèlf!’(Dutch for ‘Develop a wise mind and counsel yourself’). Thetarget group are young adults with an emotional eating disorderand who are obese. The contextual inquiry study was conductedto gain insights into the needs and experiences of the targetusers, including interviews and questionnaires with emotionaleaters, patients undergoing obesity treatment, and healthcarepractitioners. Personas and the use-case scenario were derivedfrom these results and translated into the new ‘Denk je zèlf!’virtual coach, based on Dialectical Behaviour Therapy andexperience sampling measures to capture user experience andemotional state. The main contributions of this paper are: (a)combining holistic eHealth design, behavior chain analysis, anddialectic behaviour therapy in one personalised virtual mHealthcoaching application for emotional eaters; (b) applying emotionenrichedPersonas to guide the design; (c) the results of theinitial user evaluation. Preliminary results suggest that the‘Denk je zèlf!’ virtual coach is useful for helping the targetgroup. Future research will be aimed at further iterative (re)-design and evaluation, as well as development of the dialecticaldialogues for the virtual coach and content for the education andinstruction modules.
Obesity is a fast growing societal threat, causing chronic conditions, physical and psychological health problems, as well as absenteeism and large healthcare costs. Despite numerous attempts to promote physical activity and healthy diet, existing interventions do not focus on often occurring emotional causes of obesity. There is a need for self-management support of this vulnerable target group: emotional eaters. This paper presents the results of the design case study focusing on a holistic development of a personalised virtual mHealth coach that provides self-management training ‘Denk je zèlf!’ (Dutch for ‘Develop a wise mind and counsel yourself’). Target group are young adults with emotional eating disorder and obesity. The contextual inquiry study was conducted to get insights into the needs and experiences of the target users, including interviews and questionnaires with emotional eaters, obesity treatment patients and healthcare practitioners. Personas and user stories were derived from these results and translated into a new ‘Denk je zèlf!’ virtual coach, based on Dialectical Behaviour Therapy and experience sampling measures to capture user experience and emotional state. This paper makes two main contributions: (a) combining holistic design with behaviour therapy in one virtual mHealth coaching application for emotional eaters; (b) applying Personas to guide the design. Preliminary results suggest that an online self-management training might be useful for the target group. Future research will be aimed at iterative evaluation and further development of the dialectical dialogues for the virtual coach and content for the education and instruction modules.
Background. Violent criminal offenders with personality disorders (PD’s) can cause immense harm, but are often deemed untreatable. This study aimed to conduct a randomized clinical trial to test the effectiveness of long-term psychotherapy for rehabilitating offenders with PDs. Methods. We compared schema therapy (ST), an evidence-based psychotherapy for PDs, to treatment-as-usual (TAU) at eight high-security forensic hospitals in the Netherlands. Patients in both conditions received multiple treatment modalities and differed only in the individual, study-specific therapy they received. One-hundred-three male offenders with antisocial, narcissistic, borderline, or paranoid PDs, or Cluster B PD-not-otherwise specified, were assigned to 3 years of ST or TAU and assessed every 6 months. Primary outcomes were rehabilitation, involving gradual reintegration into the community, and PD symptoms. Results. Patients in both conditions showed moderate to large improvements in outcomes. ST was superior to TAU on both primary outcomes – rehabilitation (i.e. attaining supervised and unsupervised leave) and PD symptoms – and six of nine secondary outcomes, with small to moderate advantages over TAU. ST patients moved more rapidly through rehabilitation (supervised leave, treatment*time: F(5308) = 9.40, p < 0.001; unsupervised leave, treatment*- time: F(5472) = 3.45, p = 0.004), and showed faster improvements on PD scales (treatment*- time: t(1387) = −2.85, p = 0.005). Conclusions. These findings contradict pessimistic views on the treatability of violent offenders with PDs, and support the effectiveness of long-term psychotherapy for rehabilitating these patients, facilitating their re-entry into the community
