The relationship between purpose in life and depression and anxiety: A meta-analysis

Purpose in life consists of having a sense of meaning and purpose regarding one's activities as well as an overall sense that life is meaningful. This study reports a comprehensive assessment of the relationship of purpose in life with depression and anxiety. A meta-analysis (total n = 66,468, total k = 99) investigated the association of purpose in life with depression and anxiety. Across samples, greater purpose in life was significantly associated with lower levels of depression and anxiety. The mean weighted effect size between purpose in life and depression was r = -0.49, [95% confidence intervals, CIs: -0.52, -0.45], p < 0.001. For the purpose in life and anxiety the mean weighted effect size was r = -0.36, [95% CIs: -0.40, -0.32], p < 0.001. The association of purpose in life with mental health was stronger for clinical populations, especially with regard to the relationship with anxiety. Both approach deficits and avoidance motivation are argued to play a role in the relationship between purpose and psychopathology, with greater purpose potentially limiting avoidance tendencies and reducing the effects of depression and anxiety. Understanding the role that purpose in life may play in depression and anxiety could help to inform current conceptualizations of these disorders and improve treatment outcomes.

Important Correlates of Purpose in Life Identified Through a Machine Learning Approach

OBJECTIVE

A wealth of evidence has linked purpose in life (PiL) to better mental and physical health and healthy aging. Here, the authors aimed to determine important correlates of PiL using a machine learning approach.

METHODS

Participants were recruited from retirement communities by the Rush Memory and Aging Project and assessed for childhood experience, adulthood sociodemographic factors (e.g., education, income, marital status), lifestyle and health behavior (e.g., cognitively stimulating activities, exercise, social activities, social network size), psychological factors (e.g., depression, loneliness, perceived discrimination, perceived social support), personality traits (e.g., PiL, harm avoidance), and medical conditions. Elastic Net was implemented to identify important correlates of PiL.

RESULTS

A total of 1,839 participants were included in our analysis. Among the 23 variables provided to Elastic Net, 10 were identified as important correlates of PiL. In order of decreasing effect size, factors associated with lower PiL were loneliness, harm avoidance, older age, and depressive symptoms, while those associated with greater PiL were perceived social support, more social activities, more years of education, higher income, intact late-life cognitive performance, and more middle-age cognitive activities.

CONCLUSION

Our findings identify potentially important modifiable factors as targets for intervention strategies to enhance PiL.

Social environment and quality of life among older people with diabetes and multiple chronic illnesses in New Zealand: Intermediary effects of psychosocial support and constraints

Purpose: In older people with diabetes, multimorbidity is highly prevalent and it can lead to poor quality of life. The overall purpose of this study was to examine the association between the social environment, psychosocial support and constraints, and overall quality of life among older people with and without with diabetes and multiple chronic illnesses.Methods: Self-reported data from participants in a cohort study of older New Zealanders was analysed. Responses from 380 older people diagnosed with diabetes and multiple chronic illnesses were compared with 527 older people with no health issues on indicators related to the associations of neighbourhood, health and ageing, using structural equation modelling.Results: The final model suggests that social provision, purpose in life and capabilities mediated between the social environment and quality of life, indicate that older people with positive social environment (i.e., neighbourhood advantage, residential stability) are much less likely to experience depression due to having good social support, meaningful life purpose and opportunities to engage.Conclusions: Perceived neighbourhood advantages, such as positive neighbourhood qualities, social cohesion and housing satisfaction, along with the focus on increasing social support, enhancing purpose in life and supporting one's capability to achieve, may serve as protective factors against depression.IMPLICATIONS FOR REHABILITATIONEnvironmental and personal circumstances can contribute to quality of life among older people with diabetes and multimorbidity.By providing older people with diabetes and multiple chronic illnesses a socially just environment that challenges ageism and other forms of oppression, this could reduce social disparities in health, improve inclusion and access to resources.Social and healthcare professionals are encouraged to design clinical care guidelines and rehabilitation goals from a wholistic and person/client centred approach to support older people with diabetes and multiple chronic illnesses.

Quality of life among older people with a disability: the role of purpose in life and capabilities

Purpose: Purpose in life and capabilities are two significant individual elements that enhance quality of life among older people. Capabilities refers to the extent to which older people are free to make choices that are important to them. At present, it is not known how purpose in life interacts with capabilities to influence quality of life for those living with a disability. This study examined the extent to which purpose in life and capabilities interacts with health status to affect quality of life, particularly for older people with a disability.Methods: Self-report data from participants in a longitudinal cohort study of older New Zealanders were analyzed. Responses from 452 older people with a disability were compared with 3299 age- and gender-matched older people without a disability on indicators related to health and aging. The associations were tested using hierarchical regression. Mediational impact of purpose in life and capabilities were tested via path analysis.Results: Mental health, physical health, purpose in life, and capabilities accounted for a significant amount of variance in quality of life for older people with a disability. Purpose in life and capabilities were significant unique mediators for older people with a disability.Conclusions: Purpose in life may help older people with a disability to deal with early onset stressors or changes in mental and physical health to maintain overall quality of life. The role of capabilities suggests that the social environment and access to resources and choices are important in ensuring that older people aging with or into a disability achieve quality of life in a socially just environment.Implications for rehabilitationsPurpose in life and capability are unique mediators of the relationship between health status and quality of life.Purpose in life may act as an effective buffering mechanism to deal with disability in later life while capability can empower older people with a disability to achieve quality of life in a just environment.The notion of successful aging with disability should be re-defined as using psychological, social support, and healthcare resources to live a life consistent with personal values in the context of disabilityRather than emphasizing structural factors and physical functioning in activity participation, older people with disability should be supported to decide and pursue their own preferences.Rehabilitation professionals can work flexibly with older people with disability to maximize their resilience, dignity, autonomy and choice, and positive connection to others.
