Gold kiwifruit consumption and increased vitamin C intake have been associated with improved mood, vitality, and wellbeing in healthy individuals(1,2). However, to date, no studies have focussed exclusively on the efficacy of gold kiwifruit for improving such outcomes in participants with disturbed mood. A randomised crossover trial was undertaken to examine the efficacy of ZespriTM SunGoldTM kiwifruit for improving psychological wellbeing and vitamin C concentrations in adults with sub-clinical levels of mood disturbance. In a two-period, non-blinded crossover trial, N = 26 adults aged 21 to 60 years (M = 36.1, SD = 11.0) with mild to moderate mood disturbance were randomised to a counter-balanced sequence. Participants consumed 2x SunGold kiwifruit daily or their typical diet for four weeks, with a two-week washout between periods. The primary outcome was change in mood disturbance, with secondary outcomes including plasma vitamin C, wellbeing, vitality and gut health. Results indicated a significant time x treatment interaction effect for mood disturbance (F(2,107.3) = 6.19, p = ,003) with significant improvements in mood disturbance scores between baseline and post-intervention during the SunGold kiwifruit period. A significant time x treatment interaction effect for blood plasma vitamin C (F(2,98.5) = 3.65, p = ,029) also demonstrated increased vitamin C concentrations during the SunGold kiwifruit period. A significant time x treatment interaction effect for wellbeing (F(2,104.7) = 4.5, p = ,013) was evident with wellbeing significantly improved between baseline and post-intervention during the SunGold kiwifruit period. The time x treatment interaction for vitality approached significance (F(2,104.7) = 2.89, p = ,06) with increases in vitality following SunGold kiwifruit consumption. These results provide preliminary evidence that SunGold kiwifruit consumption improves psychological wellbeing in mood-disturbed adults, which corresponds to increased plasma vitamin C concentrations. Future research is required to replicate this effect and to further demonstrate the potential benefit of whole-food interventions for treating mood-disturbance.

Self-reflection is often viewed positively; paradoxically, however, it is also associated with distress, potentially because of its relationship with rumination. Focusing self-reflection on positive themes may be one way to promote adaptive self-reflection. This study examined whether the disposition to engage in self-reflection motivates use of a journal containing positively focused writing prompts and moderates the benefit gained from it, specifically when rumination is controlled for. For 28 days, participants (N = 152) accessed an app-based mental health intervention containing various features, including the aforementioned journal. Outcomes of self-regulation and psychological wellbeing were assessed, controlling for time spent using other app features. As expected, journaling was associated with improvements in psychological wellbeing but only when baseline self-reflection was average or higher. Journaling was also initially associated with improvements in self-regulation, but this was diminished after controlling for time spent using other app features. Findings suggest self-reflection could be a strength for fostering wellbeing when it is directed in a positive way.

Loneliness is linked to many negative health outcomes and places strain on the economy and the National Health Service in the United Kingdom. To combat these issues, the determinants of loneliness need to be fully understood. Although friendships have been shown to be particularly important in relation to loneliness in older adults, this association has thus far not been explored more closely. Our exploratory study examines the relationship between number of friends and loneliness, depression, anxiety and stress in older adults. Data were obtained from 335 older adults via completion of an online survey. Measures included loneliness (UCLA Loneliness Scale version 3), depression, anxiety and stress (Depression Anxiety Stress Scales DASS-21). Participants also reported their number of close friends. Regression analyses revealed an inverse curvilinear relationship between number of friends and each of the measures tested. Breakpoint analyses demonstrated a threshold for the effect of number of friends on each of the measures (loneliness = 4, depression = 2, anxiety = 3, stress = 2). The results suggest that there is a limit to the benefit of increasing the number of friends in older adults for each of these measures. The elucidation of these optimal thresholds can inform the practice of those involved in loneliness interventions for older adults. These interventions can become more targeted; focusing on either establishing four close friendships, increasing the emotional closeness of existing friendships or concentrating resources on other determinants of loneliness in this population.

The present study is the first to examine the relations between participation in a public early childhood intervention (the Child-Parent Center (CPC) program) and psychological well-being (or, positive functioning) into early mid-life. Data are drawn from the Chicago Longitudinal Study (CLS), which has followed a cohort of 1,539 individuals who grew up in urban poverty for over four decades. Approximately two-thirds of the original study cohort participated in the CPC program in early childhood; the rest comprise a demographically matched comparison group. Participants’ psychological functioning at age 35–37 was assessed using the Ryff Scales of Psychological Wellbeing. Results support a positive relationship between CPC preschool participation and long-term psychological wellbeing. Moderated mediation (e.g., whether CPC effects on wellbeing differ across subgroups) and potential mechanisms across multiple social-ecological levels (according to the 5-Hypothesis Model of early intervention) are also empirically investigated. Future directions for child development research, early childhood intervention, and public policy are discussed.

Despite the growing use of retirement communities and ageing care facilities, little is known about how residing in retirement residences may impact aspects of older adult wellbeing. Living in these communities may hold particular influence on residents’ sense of purpose, if they feel limited in their opportunities for individual action, or could serve to promote purposefulness depending on the social connections available. The current study sought to explore contributing factors as well as barriers to purpose in older adults living in three continuing care retirement communities. Using brief semi-structured interviews, 18 older adults were asked to describe their purpose in life, community-related activities and any perceived challenges limiting their ability to pursue this purpose. Thematic analysis was used to examine themes common across interviews. Interviews presented a mixed picture of the nature of purposefulness in retirement facilities. Residents espoused several benefits of community living such as social and leisure opportunities, while also noting several obstacles to their purpose, including health concerns and the belief that purpose in life was not relevant for older adults. These findings provide insight into how older adults can derive a sense of purpose from activities within their retirement community and how facilities can better tailor programmes to promote purposefulness and support personally valued roles for residents.

Disasters can cause long-lasting damage to survivors and rescue workers. Some rescue workers suffer negative physical and psychological consequences, while others do not. Thus, it is of value to fully understand the characteristics of rescuers who have not been affected by rescue activities. Resilience refers to the ability or capacity to cope with adversity. The aim of this review is to explore and identify the characteristics of resilience among rescue workers. A systematic literature search was conducted of seven electronic databases from inception to May 2019, using keywords and medical subject heading terms related to the resilience of rescuers. Hand searches and searches of leading authors were also performed. A total of 31 articles were eligible for review. Six domains were identified to characterize the resilience of rescuers namely, demographic and physical characteristics, personality traits, coping strategies, perceived resources, being equipped with special skills for disaster rescue, and having less adverse consequences from exposure to disaster. Researchers and disaster managers can take note of these characteristics to comprehensively understand the ‘positive concept’ of resilience. This enhanced understanding of ‘positive resilience’ can in turn be used to develop a framework to assess and establish interventions, and consequently to improve the psychological wellbeing of rescuers after disaster rescue efforts.

Cette étude a pour objectif d’adapter et de valider une échelle de satisfaction des besoins psychologiques fondamentaux chez les personnes âgées (ESBP-PA). Un total de 270 participants gabonais âgés de 60 à 100 ans ont répondu au questionnaire composé de l’ESBP-PA et d’une échelle du bien-être psychologique. L’analyse factorielle exploratoire réalisée a permis d’extraire trois facteurs correspondant aux trois types de besoins psychologiques. La consistance interne, estimée par l’alpha de Cronbach et la fiabilité composite, est satisfaisante pour les trois dimensions. En ce qui concerne la validité convergente, l’analyse de corrélation a soutenu des liens significatifs entre la satisfaction des trois besoins et le bien-être psychologique. Ces résultats rendent compte des bonnes qualités psychométriques de l’instrument. Celui-ci peut être utilisé pour mesurer la satisfaction des besoins d’autonomie, de compétence et d’appartenance sociale.

In this study we used individual differences concepts and analyses to examine whether older people achieve different ageing-well states universally or whether there are identifiable key groups that achieve them to different extents. The data used in the modelling were from a prospective 16-year longitudinal study of 1,000 older Australians. We examined predictors of trajectories for ageing well using self-rated health, psychological wellbeing and independence in daily living as joint indicators of ageing well in people aged over 65 years at baseline. We used group-trajectory modelling and multivariate regression to identify characteristics predicting ‘ageing well’. The results showed three distinct and sizeable ageing trajectory groups: (a) ‘stable-good ageing well’ (classified as ageing well in all longitudinal study waves; which was achieved by 30.2% of women and 28.0% of men); (b) ‘initially ageing well then deteriorating’ (50.5% women and 47.6% men); and (c) ‘stable-poor’ (not ageing well in any wave; 19.3% women and 24.4% men). Significant gender differences were found in membership in different ageing-well states. In the stable-poor groups there were 103/533 females which was significantly lower than 114/467 men (z-statistic = −2.6, p = 0.005); women had a ‘zero’ probability of progressing to a better ageing-well classification in later years, whilst males had a one-in-five probability of actually improving. Robust final state outcome predictors at baseline were lower age and fewer medical conditions for both genders; restful sleep and Australian-born for women; and good nutrition, decreased strain, non-smoker and good social support for men. These results support that ageing-well trajectories are influenced by modifiable factors. Findings will assist better targeting of health-promoting activities for older people.

The Active Ageing Framework has been adapted as a global strategy in ageing policies, practices and research over the last decade. Lifelong learning, however, has not been fully integrated into this discourse. Using survey data provided by 416 adults (aged 60 years and above) enrolled in non-formal general-interest courses in a public continuing education programme in Canada, this study examined the association between older adults’ duration of participation in the courses and their level of psychological wellbeing, while taking their age, gender, self-rated health and vulnerability level into consideration. An analytical framework was developed based on the literature of old-age vulnerabilities and the benefits of lifelong learning. Two logistic regression and trend analyses were conducted. The results indicate that older adults’ participation is independently and positively associated with their psychological wellbeing, even among those typically classified as ‘vulnerable’. This result provides additional evidence that suggests the continuous participation in non-formal lifelong learning may help sustain older adults’ psychological wellbeing. It provides older learners, even those who are most vulnerable, with a compensatory strategy to strengthen their reserve capacities, allowing them to be autonomous and fulfilled in their everyday life. The result of this study highlights the value of the strategic and unequivocal promotion of community-based non-formal lifelong learning opportunities for developing inclusive, equitable and caring active ageing societies.

This study investigates the changes in social network types among older adults in South Korea, and it examines whether, and to what extent, these changes influence their health and psychological wellbeing. Data were obtained from the Korean Longitudinal Study of Ageing. The sample was restricted to respondents over 65 years of age who participated in both the 2006 and 2008 surveys (N = 3,501). The social network types for both years were derived by Latent Class Analysis. Changes in network types over time were then identified. A series of multivariate regression analyses were conducted to examine the effects of social network changes on self-rated health, depressive symptoms and life satisfaction. Restricted, Family, Friend and Diverse network types were derived in each wave of the study. Although the direction of social network changes was not always towards the Restricted type, the Restricted network was the most prevalent and stable type among older Koreans. Older adults who remained in or transitioned to restricted types of social networks were more likely to have poor self-rated health, higher levels of depressive symptoms and lower levels of life satisfaction. This study adds to the limited body of literature on longitudinal network typology, and it expands the knowledge of social network types among older adults in diverse social and cultural contexts.

This study examined the impact of leisure type on leisure satisfaction, along with its subsequent effects on adolescents’ psychological wellbeing, using a longitudinal sample of 3,449 Korean adolescents at two time points (2003 and 2004). The results indicated that the type of leisure activity (measured in 10th grade) had differential effects on students’ long-term psychological wellbeing (measured in 11th grade) according to sex. Specifically, for male students, only active leisure (i.e., sports activities) had a positive effect on leisure satisfaction. By contrast, for female students, although active leisure activities exerted positive effects on leisure satisfaction, passive leisure (i.e., sedentary activities) and social leisure (i.e., spending time with friends) had a negative impact on students’ leisure satisfaction. For both male and female students, leisure satisfaction had longitudinal effects on their psychological wellbeing, with increasing life satisfaction and decreasing stress.

Ageing, by definition, involves moving across lived time. Grounded in developmental psychology, particularly lifespan developmental theory, this study examines two time-related factors that may affect psychological wellbeing in adulthood. Particularly, chronological age and perceived time left to live (i.e. future time perspective) are predicted to act as opposing forces in the construction of psychological wellbeing. Young (N = 285, 19–29 years) and middle-aged adults (N = 135, 47–64 years) self-reported their current psychological wellbeing (across six dimensions) and their sense of future time perspective. As predicted, mediation analyses show that higher levels of chronological age (being in midlife), and having a more open-ended, positive future time perspective are both related to higher psychological wellbeing. Note, however, that being in midlife is related to a more limited and negative future time perspective. As such, confirming our conceptual argument, while both age and future perspective are measures of time in a general sense, analyses show that they act as unique, opposing forces in the construction of psychological wellbeing. The current research suggests that individuals can optimise psychological wellbeing to the extent that they maintain an open-ended and positive sense of the future.
