Optimal Well-Being after Major Depression

Association of probiotics, prebiotics, synbiotics or yogurt supplement with prevalence and all-cause mortality of depression: NHANES 2005-2016

BACKGROUND

A growing body of studies revealed that enteric dysbacteriosis could result in depression via the "gut-microbiota-brain axis" (GMBA). Whether probiotics, prebiotics, and synbiotics supplements could lessen the risk of depression is a topic attracting attention. This research was conducted to evaluate the relationship between probiotics, prebiotics, synbiotics, or yogurt supplements and depression with large cross-sectional data.

METHODS

All data in our research was sourced from the National Health and Nutrition Examination Survey (NHANES) (2005-2016). Probiotics, prebiotics, synbiotics, and yogurt supplements were identified using Food Frequency Questionnaire (FFQ) and Dietary Supplement Use 30-Day (DSQ). We employed the Patient Health Questionnaire (PHQ-9) for evaluating depression. Logistic regression and the Kaplan-Meier curve were performed to examine the correlation between the supplements and depression, as well as mortality.

RESULTS

A total of 17,745 adult participants were selected. The participants who supplemented probiotics, prebiotics, synbiotics, or yogurt products in the last 30 days showed a significantly lower depression rate compared with those who didn't. Specifically, the supplements could alleviate depressive symptoms including sad, anhedonia, sleep problems, fatigue, appetite changes, and psychomotor changes. This association was more prominent in specific populations such as the population aged 40-60 years, male, whites. The supplements also show more significant effects on increasing survival rates in patients with mild depression.

LIMITATION

Cross-sectional analysis reveals correlative but not causative association.

CONCLUSION

Based on the analysis of NHANES data, our research highlights the positive effect the supplements have on preventing depression, relieving depressive symptoms and increasing survival rates. This effect varied across populations.

Biological age and brain age in midlife: relationship to multimorbidity and mental health

Biological age and brain age estimated using biological and neuroimaging measures have recently emerged as surrogate aging biomarkers shown to be predictive of diverse health outcomes. As aging underlies the development of many chronic conditions, surrogate aging biomarkers capture health at the whole person level, having the potential to improve our understanding of multimorbidity. Our study investigates whether elevated biological age and brain age are associated with an increased risk of multimorbidity using a large dataset from the Midlife in the United States Refresher study. Ensemble learning is utilized to combine multiple machine learning models to estimate biological age using a comprehensive set of biological markers. Brain age is obtained using Gaussian processes regression and neuroimaging data. Our study is the first to examine the relationship between accelerated brain age and multimorbidity. Furthermore, it is the first attempt to explore how biological age and brain age are related to multimorbidity in mental health. Our findings hold the potential to advance the understanding of disease accumulation and their relationship with aging.

Contributions of Eudaimonic Well-Being to Mental Health Practice

Purpose

Synergies between a eudaimonic model of psychological well-being (Ryff, 1989) and mental health practice are examined. The model grew out of clinical, developmental, existential, and humanistic perspectives that emphasized psychological strengths and capacities, in contrast to the focus on emotional distress and dysfunction in clinical psychology.

Design/Approach

Conceptual foundations of the eudaimonic approach are described, along with the six components positive functioning that are used to measure well-being. These qualities may be important in facilitating the recovery experiences, which are of interest in Mental Health and Social Inclusion.

Findings

Four categories of empirical evidence about eudaimonia are reviewed: (1) how it changes with aging, (2) how it matters for health, (3) what are its biological and neurological underpinnings, and (4) whether it can be promoted. Major contemporary forces against eudaimonia are also considered, including ever-widening inequality, the enduring pandemic, and world-wide strife. In contrast, encounters with the arts and nature are put forth as forces for eudaimonia. The relevance of these ideas for mental health research and practice is considered.

Originality

Mental health is often defined as the absence of mental illness. The novelty of the eudaimonic approach is to define mental health as the presence of well-being, assessed with different components of positive functioning.

Practical Implications

Enormous suffering defines our contemporary world. Such realities call for greater attention to factors that undermine as well as nurture the realization of human potential, the core of eudaimonic well-being.

Psychological well-being in US veterans with non-fatal suicide attempts: A multi-cohort population-based study

BACKGROUND

Most people who survive suicide attempts neither re-attempt suicide nor die by suicide. Research on suicide attempt survivors has primarily focused on negative endpoints (e.g., increased suicide risk) rather than positive outcomes. One important outcome is psychological well-being (PWB), defined as positive functioning across emotional, intrapersonal, and interpersonal domains. We compared PWB among US military veterans with (i.e., attempt survivors) and without (i.e., non-attempters) a history of suicide attempt(s) using data from three nationally representative cohorts.

METHODS

Each US veteran cohort (Cohort1: N = 3148; Cohort2: N = 1474; Cohort3: N = 4042) completed measures of suicidality (e.g., attempt history), character strengths (e.g., curiosity, optimism), psychological symptoms (e.g., depression), and indicators of PWB (e.g., happiness). t-Tests were conducted to examine group differences in PWB; hierarchical regressions were conducted to examine suicide attempt status as a predictor of PWB controlling for symptoms and demographics. Multivariable regressions were conducted to identify predictors of PWB among attempt survivors.

RESULTS

In each cohort, reported PWB was markedly lower among suicide attempt survivors than non-attempters (ds = 0.9-1.2), even after adjusting for mental health symptoms. Individual differences in PWB were observed, with a subset of suicide attempt survivors reporting higher PWB levels than non-attempters (1.4-7.4 %). Curiosity and optimism were positively associated with PWB among suicide attempt survivors (rs = 0.60-0.78).

LIMITATIONS

Data were cross-sectional, limiting inferences about causation and directionality of associations.

CONCLUSIONS

Findings highlight diminished PWB as an important and understudied concern among veteran attempt survivors. Collectively, our findings underscore the importance of considering PWB in the research, assessment, and treatment of suicidality.

Well-Being After Psychopathology: A Transformational Research Agenda

If one struggles with depression, anxiety, or suicidal impulses, what is the best outcome that one can hope for? Can psychopathology be a bridge to a better place where people operate with autonomy and self-mastery, enjoy healthy relationships, experience frequent positive emotions, and view life as meaningful and purposeful? Studies of national samples have revealed that a substantial number of people with depression, panic disorder, and suicidal impulses go on to achieve high levels of psychological well-being. We consider the practical and theoretical implications of these findings and call for a transformational mental-health agenda that focuses on good outcomes.

Future Well-Being Among U.S. Youth Who Attempted Suicide and Survived

To what extent does a suicide attempt impair a person's future well-being? We estimated the prevalence of future well-being (FWB) among suicide attempt survivors using a nationally representative sample of 15,170 youths. Suicide attempt survivors were classified as having high FWB if they reported (a) a suicide attempt at Wave I, (b) no suicidal ideation or attempts over the past year at Wave III (7 years after), and (c) a well-being profile at or above the top quartile of nonsuicidal peers. Seventy-five of 574 suicide attempt survivors (∼13%) met criteria for FWB at Wave III, compared to 26% of nonsuicidal peers. Wave I well-being levels, not depressive symptoms, predicted the likelihood of FWB at Wave III (OR = 1.23, 95% CI [1.05, 1.44], p < .05). In conclusion, a nonfatal suicide attempt reduced but did not preclude FWB in a large national sample. The observation that a segment of the population of suicide attempt survivors achieves FWB carries implications for the prognosis of suicidal behavior and the value of incorporating well-being into investigations of suicide-related phenomena.

Positive and meaningful lives: Systematic review and meta-analysis of eudaimonic well-being in first-episode psychosis

BACKGROUND

First-episode psychosis typically has its onset during adolescence. Prolonged deficits in social functioning are common in FEP and yet often variance in functioning remains unexplained. Developmental psychology frameworks may be useful for understanding these deficits. Eudaimonic well-being (EWB), or positive self-development, is a developmental psychology construct that has been shown to predict mental health outcomes across multiple populations but has not been systematically reviewed in FEP.

AIM

Our aim was to systematically review the evidence for: the predictors of EWB, the effectiveness of EWB interventions and to examine the quality of this research in FEP.

METHODS

Selected studies measured either composite or components of EWB. A systematic search produced 2876 abstracts and 122 articles were identified for full screening which produced 17 final papers with 2459 participants.

RESULTS

Studies comprised six RCTs, eight prospective follow-up studies and three case-controlled studies. Self-esteem and self-efficacy were the most commonly measured components. A meta-analysis of RCTs revealed no statistically significant effect of interventions on self-esteem. The extant research indicates that character strengths may be associated with higher EWB. Self-esteem may be lower in FEP compared with age matched controls but not different from ultra-high risk patients. Self-esteem appears to be associated with poorer insight and improved therapeutic alliance. Significant problems with both external and internal validity of reviewed studies were apparent.

CONCLUSIONS

The hypotheses that lowered EWB is a risk factor for both onset of FEP and for poorer functional outcomes warrant further investigation. There is currently no evidence for effective interventions for EWB in FEP.

Future Well-Being Among People Who Attempt Suicide and Survive: Research Recommendations

Over 48,000 people died by suicide in 2018 in the United States, and more than 25 times that number attempted suicide. Research on suicide has focused much more on risk factors and adverse outcomes than on protective factors and more healthy functioning. Consequently, little is known regarding relatively positive long-term psychological adaptation among people who attempt suicide and survive. We recommend inquiry into the phenomenon of long-term well-being after nonfatal suicide attempts, and we explain how this inquiry complements traditional risk research by (a) providing a more comprehensive understanding of the sequelae of suicide attempts, (b) identifying protective factors for potential use in interventions and prevention, and (c) contributing to knowledge and public education that reduce the stigma associated with suicide-related behaviors.

Optimal well-being in the aftermath of anxiety disorders: A 10-year longitudinal investigation

BACKGROUND

Although preliminary research has explored the possibility of optimal well-being after depression, it is unclear how rates compare to anxiety. Using Generalized Anxiety Disorder (GAD) and Panic Disorder (PD) as exemplars of anxiety, we tested the rates of optimal well-being one decade after being diagnosed with an anxiety disorder. Based on reward deficits in depression, we pre-registered our primary hypothesis that optimal well-being would be more prevalent after anxiety than depression as well as tested two exploratory hypotheses.

METHOD

We used data from the Midlife in the United States (MIDUS) study, which contains a nationally representative sample across two waves, 10 years apart. To reach optimal well-being, participants needed to have no symptoms of GAD, PD, or major depressive disorder (MDD) at the 10 year follow-up and exceed cut-offs across nine dimensions of well-being.

RESULTS

The results failed to support our primary hypothesis. Follow-up optimal well-being rates were highest for adults previously diagnosed with MDD (8.7%), then PD (6.1%), and finally GAD (0%). Exploratory analyses revealed optimal well-being was approximately twice as prevalent in people without anxiety or depression at baseline and provided partial support for baseline well-being predicting optimal well-being after anxiety. Results were largely replicated across different classifications of optimal well-being.

LIMITATIONS

Findings are limited by the somewhat unique measurement of anxiety in the MIDUS sample as well as the relatively high rate of missing data.

CONCLUSIONS

We discuss possible explanations for less prevalent optimal well-being after anxiety vs. depression and the long-term positivity deficits from GAD.

Derailment within the landscape of psychopathology

When perceived changes in course occur, individuals can be left feeling disconnected from who they were in the past. This sensation of being 'off-course' in life is an individual difference we call 'derailment.' In this article, we review derailment's unique contribution to the psychological literature, the role of perceived self and identity change in mental health, and the nuanced association between derailment and depression. Although depression has been emphasized in research to date, we argue for derailment's role in other types of mental illness, motivating several exciting directions for future work. For the pervasiveness of identity in our everyday lives, the study of derailment confers opportunities for better understanding the experience of psychopathology and approaching its treatment.

The unique predictive value of discrete depressive symptoms on derailment

BACKGROUND

Studies have consistently demonstrated a positive cross-sectional association between depressive symptoms and derailment, or the sense of being "off-course" in life. Still unknown is whether all symptoms of depression similarly relate to derailment. Given that depressive symptoms do not weigh equally in the prediction of other important outcomes, this study aimed to bridge the gap between these novel findings and emerging perspectives focused on the impact of individual depressive symptoms.

METHODS

The study was preregistered prior to data collection. The analytic sample contained 1,457 adults (M_age = 37.46 years, 54.22% female) recruited from Amazon's Mechanical Turk. Participants self-reported on depression using the Patient Health Questionnaire-9, and perceived changes in identity and self-direction using the Derailment Scale.

RESULTS

All symptoms of depression shared positive unadjusted associations with derailment. Feelings of failure, fatigue, and sleep problems shared positive unique associations with derailment, and represented the top three contributors to the explained variance in derailment.

LIMITATIONS

This study relied on self-report methods, making results vulnerable to bias (e.g., social desirability, errors in memory, interpretation).

CONCLUSIONS

As work understanding the association between depressive symptoms and derailment continues to unfold, this study has provided markers for researchers and clinicians by suggesting that those who feel like they have failed, are fatigued, or report sleep problems may be the most likely to feel off-course and disconnected from their past selves. This work helps establish the utility of considering identity within the context of mental health, and future directions stemming from these findings are discussed.
