About Me

I graduated at the University of Twente and completed my Master of Science in Positive Psychology and Technology. During my study, I developed a strong interest in concepts of positive clinical psychology, psychological disorders and how to promote mental health. Since 2017, I'am working as researcher at the department of Psychology, Health & Technology at the University of Twente. The focus of my PhD thesis lies on the effectivenes of a multi-component positive psychology intervention to enhance well-being and personal recovery in patients with bipolar disorders.

Enhancing well-being in patients with bipolar disorder

In the course of my PhD thesis, me and my colleagues focus on the development, implementation and validation of a multi-component positive psychology intervention for patients with bipolar disorders.

The study aims to investigate whether the intervention as an adjunct to care as usual offered to patients with bipolar disorder, is effective in the short and long term in improving outcomes of mental health, personal recovery and psychopathology and to reduce relapse. Furthermore, we aim to explore possible working mechanisms for the intervention, including positive emotions, positive emotion regulation, self-compassion and positive relationships. Preliminary results are expected in summer 2019.

This PhD project is supervised by prof. dr. Ernst Bohlmeijer, prof. dr. Ralph Kupka, dr. Peter ten Klooster and dr. Melissa Chrispijn.

Validation of the Responses to Positive Affect Questionnaire

Cognitive responses to affective states are an important factor for the onset, maintenance and recurrence of mood disorders such as bipolar disorder. The Responses to Positive Affect Questionnaire (RPA) is a valid measure to assess cognitive responses to positive affect. However, the RPA has not been validated in clinical samples yet. In this cross-sectional survey research we aim to investigate the psychometric properties and utility of the RPA in a clinical sample of people with bipolar disorders.

The effect of positive psychology interventions on well-being in clinical populations: a systematic review and meta-analysis

Positive psychology interventions (PPIs) show beneficial effects on mental health in non-clinical populations, but the current literature is inconclusive regarding its effectiveness in clinical settings. The aim of this systematic review and meta-analysis was to examine the effects of PPIs on well-being (primary outcome), depression, anxiety, and stress (secondary outcomes) in clinical samples with psychiatric or somatic disorders. Findings indicate that PPIs, wherein the focus is on eliciting positive feelings, cognitions or behaviors, not only have the potential to improve well-being, but can also reduce distress in populations with clinical disorders.

Feasibility, acceptability and effectiveness of positive psychology interventions in serious mental illness: a systematic review

Positive psychology interventions (PPIs) have been shown to improve well-being in healthy individuals, people with mild to moderate psychopathology and in clinical populations. However, the effect of PPIs in individuals with severe mental illness is scarcely known. The aim of the current study was to systematically review literature on applications of positive psychology in severe mental illness and examine the effectiveness of PPIs in improving mental health and clinical outcomes.

BiPositive: Enhancing well-being and personal recovery in patients with bipolar disorder

During his PhD project, Jannis aims to evaluate the effectiveness of an innovative multi-component positive psychology intervention for patients with bipolar disorder (BD). BD is characterized by recurrent depressive, (hypo)manic or mixed episodes that alternate with phases, in which patients are relatively symptom free (i.e. euthymic phase). Treatment for BD during the euthymic phase often focuses on symptomatic and functional recovery. The chance of relapse into mood episodes is high and needs of patients relating to improvement of well-being and personal recovery are often unmet. The focus of the intervention lies on enhancing personal recovery in patients with BD by improving well-being. In the course of this 8-week  group intervention participants learn to savor positive experiences, to identify and use personal strengths, to formulate life-goals, and to apply optimism in relation to these life-goals. The goal of the intervention is to improve well-being and personal recovery and avoid relapse into depressive or (hypo)manic phases.
