The relative importance of rumination, experiential avoidance and mindfulness as predictors of depressive symptoms

The role of experiential avoidance in the early stages of an online mindfulness-based intervention: Two mediation studies

Objectives There is evidence to suggest that only 2-4 weeks of mindfulness-based interventions (MBIs) can already alleviate emotional stress. The current studies sought to examine whether experiential avoidance mediated the effects of MBIs on emotional distress during an early stage of the intervention. Methods: Chinese participants with high emotional distress were recruited. Study 1 included 324 participants, randomly assigned to an online MBI (N = 171) or a control group (N = 153). Experiential avoidance and general emotional distress were measured at baseline and after the 3rd week of the intervention. Study 2 included 158 participants, randomly assigned to an online MBI (N = 79) or a control group (N = 79). Experiential avoidance and emotional distress were measured at baseline and weekly in the first three weeks. Results: Compared to the control group, experiential avoidance and emotional distress were significantly improved in the MBI group during the first three weeks of the intervention (Cohen's d = 0.22-0.63). Moreover, changes in experiential avoidance mediated the effects of MBI on emotional distress in the early stage in both contemporary and lagged mediation models. Discussion: Experiential avoidance is an important mediator during the early-stage of MBIs for alleviating emotional distress.

Assessing the mindfulness predictors of mental health: does mindfulness practise or dispositional mindfulness better protect young peoples' mental health?

Background

University is an important time in a young person's life. Although it is a time of exploration, self-discovery and socialising, it is also a time of increased vulnerability to mental health problems such as anxiety and depression. Studies have shown that engagement in mindfulness activities can have a positive effect on mental health. However, research is limited in its scope in particular in relation to stressful (transitional) periods of life.

Methods

The current study aims to address this issue by providing evidence on the predictive impact of both mindfulness practice and 'dispositional' (or trait) mindfulness on students' mental health. In total, we gathered data from 190 first-year students.

Results

A multiple regression was utilised for data analysis. This showed that 'dispositional' mindfulness, but not mindful activity had a significant impact on mental health scores.

Conclusion

This provides data for future research into the effectiveness of mindfulness interventions for student adaptation to university and potential interventions.

Transdiagnostic factors in symptoms of depression and post-traumatic stress: a systematic review

The current systematic review sought to identify quantitative empirical studies that focused on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination, and their relation with depression and post-traumatic stress disorder (PTSD). The overall research aim was to examine the relationship between these transdiagnostic factors and their relation with depression and PTSD symptoms. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Out of the 768 articles initially identified, 55 met the inclusion criteria for the current review. The results determined that intolerance of uncertainty is indirectly related to depression and PTSD symptoms, mainly through other factors including emotion dysregulation and rumination. Additionally, emotional dysregulation is a significant predictor of both depression and PTSD symptoms. Rumination is a robust factor related to depression and PTSD symptoms, this relationship was significant in cross-sectional and longitudinal studies. This review provides evidence on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination in the relationship with depression and PTSD symptoms.

Longitudinal Associations between Internalizing Symptoms, Dispositional Mindfulness, Rumination and Impulsivity in Adolescents

Mindfulness has been associated with fewer negative mental health symptoms during adolescence, but fewer studies have examined longitudinal associations between mindfulness and symptoms in conjunction with two vulnerability factors for psychopathology with mindfulness: rumination and impulsivity. This study examined longitudinal associations between internalizing symptoms (depression, anxiety, stress), mindfulness, rumination, and impulsivity over a one-year period among 352 Spanish adolescents (57.4% girls; M = 14.47, SD = 1.34). Participants completed self-reported measures of symptoms, mindfulness, rumination, and impulsivity at two time points. Mindfulness negatively predicted stress and depressive symptoms, and a bidirectional negative association was found between mindfulness and impulsivity. Impulsivity positively predicted stress, and anxiety positively predicted depressive symptoms, stress, and rumination. This study highlights the importance of mindfulness as a protective factor and impulsivity and anxiety as risk factors for internalizing symptoms throughout adolescence. These findings build on previous studies that examined longitudinal associations between mindfulness and symptoms by including rumination and impulsivity’s roles.

Cognitive arousal mediates the relationship between perceived ostracism and sleep quality but it is not moderated by experiential avoidance

Previous research suggests that longer-term perceived ostracism is related to poor sleep quality. In this study, we investigated the mediating effect of cognitive arousal on the perceived ostracism-sleep quality relationship. We also investigated whether experiential avoidance was a moderator of the cognitive arousal-sleep quality relationship. Participants (N = 251) were recruited through online research portals to take part in an online survey. A path analysis was used to test a moderated mediation effect between variables. It was found that cognitive arousal mediated the perceived ostracism-sleep quality relationship; however, experiential avoidance was not a significant moderator. These findings suggest that further research needs to be conducted to elucidate the mechanism of experiential avoidance to account for when it may impact sleep quality. Moreover, treatment interventions targeted at reducing cognitive arousal (e.g., cognitive behavioural therapy) prior to sleep are likely to bear some fruit.

Work-Family Conflict and Mindful Parenting: The Mediating Role of Parental Psychopathology Symptoms and Parenting Stress in a Sample of Portuguese Employed Parents

Aims: The aims of the current study are to examine whether parents' work-family conflict, emotional distress (anxiety/depressive symptoms and parenting stress) and mindful parenting vary according to the type of employment (full-time, part-time, and occasional), the type of work schedule (fixed, flexible, and shift), and the number of working hours per week and to explore whether parental emotional distress mediates the association between work-family conflict and mindful parenting dimensions. Methods: A sample of 335 employed parents (86.3% mothers) of children and adolescents between the ages of 1 and 19 years old completed a sociodemographic form and measures of work-family conflict, anxiety/depression symptoms, parenting stress, and mindful parenting. The differences in study variables among types of employment, work schedules and number of weekly working hours were analyzed. A path model was tested through structural equation modeling in AMOS to explore the indirect effect of work-family conflict on mindful parenting dimensions through anxiety, depression and parenting stress. The invariance of the path model across children's age groups (toddlers, preschool and grade school children, and adolescents) and parents' gender was also examined. Results: Parents with a shift work schedule, working full-time and 40 h or more per week, presented significantly higher levels of work-family conflict than those with a fixed or flexible schedule, working part-time and less than 40 h per week, respectively. Parents with a flexible work schedule presented significantly higher levels of self-regulation in parenting and of non-judgmental acceptance of parental functioning than parents with a shift work schedule. Higher levels of work-family conflict were associated with lower levels of mindful parenting dimensions through higher levels of anxiety/depression symptoms and parenting stress. The model was invariant across children's age groups and parents' gender. Discussion: Work-family conflict is associated with poorer parental mental health and with less mindful parenting. Workplaces should implement family-friendly policies (e.g., flexible work arrangements) that help parents successfully balance the competing responsibilities and demands of their work and family roles. These policies could have a critical impact on the mental health of parents and, consequently, on their parental practices.
