Developmental trajectories of experiential avoidance and depressive symptoms and association to health behaviors among adolescents during brief guided online acceptance and commitment therapy
Abstract While many children and adolescents experience psychological problems with up to 20 percent estimated to develop a mental health problem, only few receive treatment. Online interventions can help respond to the need of support among young people without requiring considerable resources. However, relatively few studies have examined the efficacy of online interventions for youth and more research is needed to understand individual differences in benefiting from these interventions. The current study sought to examine different developmental trajectories of experiential avoidance and depressive symptoms and their association to health behaviors measured at baseline during a brief gui…
The role of psychological inflexibility in adolescent satisfaction with the educational track and school dropout intentions
This study aimed to obtain novel understanding of the associations between psychological inflexibility and adolescents' engagement with upper secondary studies. The participants were 885 Finnish adolescents (mean age 15.74 at the outset) whose psychological inflexibility was measured with the short form of the Acceptance and Fusion Questionnaire for Youth (AFQ-Y8) in the fall of the final (ninth) grade of basic education. School engagement was measured as satisfaction with the educational track and as school dropout intentions, and they were measured twice in the first study year after the transition to upper secondary education. The results showed that high psychological inflexibility in t…

A concept to empower self-management of psychophysiological wellbeing: preliminary user study experiences.
In prevention of chronic diseases, health promotion and early interventions based on self-management should be emphasized. Mental health problems and stress cause a significant portion of healthcare costs, and also complicate the management of other chronic conditions. In addition to physical health, psychophysiological and social wellbeing should be equally promoted. Thus, we have previously designed and reported the P4Well or Pervasive Personal and PsychoPhysiological management of WELLness concept for working-age citizens. The concept supports the stress and recovery management on a daily basis through improved health management strategies, and combines psychological methods with persona…

Psychological inflexibility explains distress in parents whose children have chronic conditions
Experiential avoidance, cognitive defusion, and mindfulness have all been associated with psychological disorders and well-being. This study investigates whether they predict psychological distress, i.e., symptoms of burnout, depression, stress and anxiety, in parents of children with chronic conditions. We hypothesized that these factors would exhibit a large degree of common variance, and that when compared to mindfulness and defusion, experiential avoidance on its own would predict a larger proportion of unique variance. 75 parents of children with chronic conditions having burnout symptoms who participated in an intervention study completed measures of burnout, stress, anxiety, depressi…
