Psychological characteristics and stress differentiate between high from low health trajectories in later life: a machine learning analysis.

Objective: This study set out to empirically identify joint health trajectories in individuals of advanced age. Predictors of subgroup allocation were investigated to identify the impact of psychological characteristics, stress, and socio-demographic variables on more favorable aging trajectories.Method: The sample consisted of N = 334 older adults (MAGE=68.31 years; SD = 9.71). Clustered health trajectories were identified using a longitudinal variant of k-means and were based on health and satisfaction with life. Random forests with conditional interference were computed to examine predictive capabilities. Key predictors included psychological resilience resources, exposure to childhood adversities, and chronic stress. Data was collected via a survey, at two different time points one year apart.Results: Two different clustered health trajectories were identified: A 'constant high health' (low number of health-related symptoms, 65.6%) and a 'maintaining low health' profile (high number of symptoms, 34.4%). Over the one-year study period, both symptom profiles remained stable. Random forest analyses showed chronic stress to be the most important predictor in the interaction with other risk and also buffering factors.Conclusion: This study provides empirical evidence for two stable health trajectories in later life over one year. These results highlight the importance of chronic stress, but also psychological resilience resources in predicting aging trajectories.

Childhood Adversities and Thriving Skills: Sample Case of Older Swiss Former Indentured Child Laborers.

OBJECTIVE: The study of life-long consequences of severe childhood adversities or trauma has recently received much attention. However, little is known about the subjective coping success and development of positively evaluated resources that may originate within these adverse experiences and may be conceptualized as thriving. This study set out to examine the relationship between thriving in response to early adversity and successful aging with a sample of former indentured child laborers in Switzerland (Verdingkinder). METHODS: Participants were screened according to subjective and objective health-related attributes, and those who were evaluated to be "successful agers" were included. Semistructured interviews were conducted with 12 former Verdingkinder (mean age: 71 years) that lasted 60-120 minutes. The interviews were analyzed using the paradigm model of the Grounded Theory. RESULTS: In the interviews adverse experiences and negative consequences were reported. However, where thriving was triggered in response to these experiences, the factors identified as "lightheartedness," "social purpose," and "self-enhancement" were associated with successful aging. Factors including motivation, reflection, personality traits, social support, individual coping strategies, turning points, and processing were reported as central to thriving. CONCLUSION: The identified factors show similarities with established predictors of health and well-being. Thus, under certain circumstances early and prolonged adverse experiences can also provide the opportunity to develop positive resources for successful aging.

Comparing personal insight gains due to consideration of a recent dream and consideration of a recent event using the Ullman and Schredl dream group methods.

There have been reports and claims in the psychotherapeutic literature that the consideration of recent dreams can result in personal realizations and insight. There is theoretical support for these claims from work on rapid eye movement (REM) sleep having a function of the consolidation of emotional memories and the creative formation of connections between new and older memories. To investigate these claims, 11 participants (10 females, one male) reported and considered a recent home dream in a dream discussion group that following the "Appreciating dreams" method of Montague Ullman. The group ran 11 times, each participant attending and participating once. A further nine participants (seven females, two males) reported and considered a recent home dream in a group that followed the "Listening to the dreamer" method of Michael Schredl. The two studies each had a control condition where the participant also reported a recent event, the consideration of which followed the same technique as was followed for the dream report. Outcomes of the discussions were assessed by the participants on the Gains from Dream Interpretation (GDI) scale, and on its counterpart, the Gains from Event Interpretation scale. High ratings on the GDI experiential-insight subscale were reported for both methods, when applied to dreams, and for the Ullman method Exploration-Insight ratings for the dream condition were significantly higher than for the control event condition. In the Ullman method, self-assessment of personal insight due to consideration of dream content was also significantly higher than for the event consideration condition. The findings support the view that benefits can be obtained from the consideration of dream content, in terms of identifying the waking life sources of dream content, and because personal insight may also occur. To investigate the mechanisms for the findings, the studies should be repeated with REM and non-REM dream reports, hypothesizing greater insight from the former.
