BackgroundThe use of positive psychological interventions may be considered as a complementary strategy in mental health promotion and treatment. The present article constitutes a meta-analytical study of the effectiveness of positive psychology interventions for the general public and for individuals with specific psychosocial problems.MethodsWe conducted a systematic literature search using PubMed, PsychInfo, the Cochrane register, and manual searches. Forty articles, describing 39 studies, totaling 6,139 participants, met the criteria for inclusion. The outcome measures used were subjective well-being, psychological well-being and depression. Positive psychology interventions included self-help interventions, group training and individual therapy.ResultsThe standardized mean difference was 0.34 for subjective well-being, 0.20 for psychological well-being and 0.23 for depression indicating small effects for positive psychology interventions. At follow-up from three to six months, effect sizes are small, but still significant for subjective well-being and psychological well-being, indicating that effects are fairly sustainable. Heterogeneity was rather high, due to the wide diversity of the studies included. Several variables moderated the impact on depression: Interventions were more effective if they were of longer duration, if recruitment was conducted via referral or hospital, if interventions were delivered to people with certain psychosocial problems and on an individual basis, and if the study design was of low quality. Moreover, indications for publication bias were found, and the quality of the studies varied considerably.ConclusionsThe results of this meta-analysis show that positive psychology interventions can be effective in the enhancement of subjective well-being and psychological well-being, as well as in helping to reduce depressive symptoms. Additional high-quality peer-reviewed studies in diverse (clinical) populations are needed to strengthen the evidence-base for positive psychology interventions.
There is a growing consensus that mental health is not merely the absence of mental illness, but it also includes the presence of positive feelings (emotional well-being) and positive functioning in individual life (psychological well-being) and community life (social well-being). We examined the structure, reliability, convergent validity, and discriminant validity of the Mental Health Continuum-Short Form (MHC-SF), a new self-report questionnaire for positive mental health assessment. We expected that the MHC-SF is reliable and valid, and that mental health and mental illness are 2 related but distinct continua. This article draws on data of the LISS panel of CentERdata, a representative panel for Longitudinal Internet Studies for the Social Sciences (N = 1,662). Results revealed high internal and moderate test-retest reliability. Confirmatory factor analysis (CFA) confirmed the 3-factor structure in emotional, psychological, and social well-being. These subscales correlated well with corresponding aspects of well-being and functioning, showing convergent validity. CFA supported the hypothesis of 2 separate yet related factors for mental health and mental illness, showing discriminant validity. Although related to mental illness, positive mental health is a distinct indicator of mental well-being that is reliably assessed with the MHC-SF.
Mental health has long been defined as the absence of psychopathologies, such as depression and anxiety. The absence of mental illness, however, is a minimal outcome from a psychological perspective on lifespan development. This article therefore focuses on mental illness as well as on three core components of positive mental health: feelings of happiness and satisfaction with life (emotional well-being), positive individual functioning in terms of self-realization (psychological well-being), and positive societal functioning in terms of being of social value (social well-being). The two continua model holds that mental illness and mental health are related but distinct dimensions. This model was studied on the basis of a cross-sectional representative internet survey of Dutch adults (N = 1,340; 18–87 years). Mental illness was measured with the Brief Symptom Inventory and mental health with the Mental Health Continuum Short Form. It was found that older adults, except for the oldest-old, scored lower on psychopathological symptoms and were less likely to be mentally ill than younger adults. Although there were fewer age differences for mental health, older adults experienced more emotional, similar social and slightly lower psychological well-being. In sum, today’s older adults have fewer mental illness problems, but they are not in a better positive mental health than today’s younger adults. These findings support the validity of the two continua model in adult development.
Evidence is accumulating on the effects of subjective aging-that is, how individuals perceive their own aging process-on health and survival in later life. The goal of this article is to synthesize findings of existing longitudinal studies through a meta-analysis. A systematic search in PsycInfo, Web of Science, Scopus, and Pubmed resulted in 19 longitudinal studies reporting effects of subjective aging on health, health behaviors, and longevity. The authors combine the outcomes reported in these studies using a random effects meta-analysis, assuming that there would be differences in effect sizes across studies. The meta-analysis resulted in an overall significant effect of subjective aging (likelihood ratio = 1.429; 95% confidence interval = 1.273-1.604; p < .001). The analyses revealed heterogeneity, with stronger effects for studies with a shorter period of follow-up, for studies of health versus survival, for studies with younger participants (average age of the studies varies between 57 and 85 years with a median of 63 years), and for studies in welfare systems where state provisions of welfare are minimal. However, effects did not vary either across different operationalizations of subjective aging or by study quality. Subjective aging has a small significant effect on health, health behaviors, and survival. Further theoretical conceptualizations and empirical studies are needed to determine how subjective aging contributes to health and survival.
The personal experience of aging, the resources relevant to it, and the consequences for subjective well-being were investigated in a sample of 4034 Germans aged 40 to 85. The data revealed 3 dimensions of aging experiences as particularly relevant: (a) physical decline, (b) continuous growth, and (c) social loss. Not only being younger but also having better subjective health, higher income, less loneliness, higher education, and greater hope were negatively associated with physical decline and social loss and positively associated with continuous growth. The number of children participants had played no role. All three dimensions of the aging experience were also found to be related to both positive and negative affect and, with the exception of physical decline, to life satisfaction.
Age identities play a role in more varied aspects of psychosocial adaptation in the United States than in Germany. It is concluded that the cultural context needs to be included more explicitly in gerontological theories and research.
BackgroundThere is a rapidly growing interest in psychological well-being (PWB) as outcome of interventions. Ryff developed theory-based indicators of PWB that are consistent with a eudaimonic perspective of happiness. Numerous interventions have been developed with the aim to increase PWB. However, the effects on PWB measured as coherent outcome have not been examined across studies yet. This meta-analysis of randomized controlled trials of behavioral interventions aims to answer the question whether it is possible to enhance PWB.MethodsA systematic literature search was performed in PsycINFO, Cochrane and Web of Science. To be included, studies had to be randomized controlled trials of behavioral interventions with psychological well-being as primary or secondary outcome measure, measured with either Ryff’s Psychological Well-Being Scales or the Mental Health Continuum—Short Form. The meta-analysis was performed using a random effects model. From the 2,298 articles found, 27 met the inclusion criteria. The included studies involved 3,579 participants.ResultsWe found a moderate effect (Cohen’s d = 0.44; z = 5.62; p < .001). Heterogeneity between the studies was large (Q (26) = 134.12; p < .001; I2 = 80.62). At follow-up after two to ten months, a small but still significant effect size of 0.22 was found. There was no clear indication of publication bias. Interventions were more effective in clinical groups and when they were delivered individually. Effects were larger in studies of lower quality.ConclusionsIt appears to be possible to improve PWB with behavioral interventions. The results are promising for the further development and implementation of interventions to promote PWB. Delivering interventions face-to-face seems to be the most promising option. We recommend to keep including clinical groups in the research of psychological well-being. Heterogeneity is a limitation of the study and there is need for more high-quality studies.
Humans are able to reflect on and interpret their own aging. Thus, as individuals grow older, calendar age may become increasingly a subjective variable. This theoretical paper proposes the concept of Awareness of Aging (AoA) as a superordinate construct that can serve an integrative function in developmental research on subjective aging. It is argued that the AoA construct can incorporate the theoretical components of other existing concepts by acknowledging that judgments of subjective aging tend to be made on an awareness continuum ranging from pre-conscious/implicit to conscious/explicit. We also argue that processes of AoA are inherently self-related processes and that AoA is a particular aspect of self-awareness that results in specific aging-related self-knowledge. Over time, aging individuals incorporate this self-knowledge into their self-concept and personal identity. We provide theoretical evidence showing that although all major theories of adult development and aging draw on phenomena related to AoA, the explicit incorporation of aging-related awareness processes has been missing. We also provide an overarching framework to illustrate in a heuristic way how AoA in combination and interaction with other influences affects developmental outcomes. Finally, we argue that attention to AoA-related processes has a number of societal and applied implications and thereby addresses issues of applied developmental psychology.
