An Integrative Approach to Promote Subjective Well-being and Mental Health Based on Transdiagnostic Intervention Components

<i>Background</i>: Despite the vast amount of experimental and correlational studies and the various attempts to understand the mechanisms of change of psychological interventions, researchers and practitioners are still facing unanswered questions about how intervention programs work, and which factors are those which contribute significantly to improvements in mental health and well-being. Numerous programs were developed with varying concepts and theoretical foundations: Each approach has displayed a relevant amount of empirical evidence in fostering mental health which justifies their backing within the researcher and practitioners’ community. Yet, we still don´t know which intervention components and specific factors are relevant to actual change. <i>Method</i>: In this study, a systematic literature review was conducted to analyze existing research related to psychological interventions. <i>Aim</i>: The aim of this study was to provide an overview of current findings on emotional support and integrate them into a comprehensive framework. <i>Results</i>: We present a unifying conceptual framework to integrate those concepts based on a transdiagnostic basis and humanistic conception of human beings. Following the ideas of transdiagnostic approaches, we propose four central components: Mindfulness (MI), Emotion Regulation (ER), Self-Reflection (SR) and Resource Activation (RA) underlying and targeting different psychological processes leading to inner change. <i>Limitations</i>: The limitation of this study is that no empirical approaches were pursued. <i>Conclusion</i>: Despite their initially different approaches, those can meaningfully be integrated into a conceptual framework. It would be desirable for the focus to be more on how different concepts can complement each other.
