Accurately predicting users’ perceived stress is beneficial to aid early intervention and prevent both mental illness and physical disease during the COVID-19 pandemic. However, the existing perceived stress predicting system needs to collect a large amount of previous data for training but has a limited prediction range (i.e., next 1–2 days). Therefore, we propose a perceived stress prediction system based on the history data of micro-EMA for identifying risks 7 days earlier. Specifically, we first select and deliver an optimal set of micro-EMA questions to users every Monday, Wednesday, and Friday for reducing the burden. Then, we extract time-series features from the past micro-EMA responses and apply an Elastic net regularization model to discard redundant features. After that, selected features are fed to an ensemble prediction model for forecasting fine-grained perceived stress in the next 7 days. Experiment results show that our proposed prediction system can achieve around 4.26 (10.65% of the scale) mean absolute error for predicting the next 7 day’s PSS scores, and higher than 81% accuracy for predicting the next 7 day’s stress labels.

Background The medical management of patients with pulmonary hypertension (PH) has advanced, with few evidence-based recommendations about psychosocial and behavioral health interventions. There is also a lack of comprehensive understanding of PH psychosocial and behavioral health needs. Some psychosocial and behavioral health interventions have been tested; however, there is a gap in the systematic evaluation of nonpharmacological complementary approaches to augment PH management when addressing psychosocial and behavioral health needs. Objectives The objectives are to explore psychosocial and behavioral health needs and describe psychosocial and behavioral health interventions for patients with PH. Methods We conducted an integrative systematic review of publications between January 1, 2010, and January 31, 2020, obtained from electronic databases: EMBASE, PubMed, Cumulative Index of Nursing and Allied Health Literature, Cochrane, PsycINFO, and Web of Science. The literature searches focused on empirical literature reporting psychosocial needs and psychosocial and behavioral health interventions for adult PH patients. We included peer-reviewed studies published in English. Search terms used in the study were: “hypertension,” “pulmonary hypertension,” “psychosocial,” “depression,” “anxiety,” “quality of life,” “behavioral health,” “self-management,” “psychosocial intervention,” and “psychological distress.” Excluded were opinion and discussion publications, reviews, non-PH populations, and pediatric articles. We used the constant comparison method to guide the synthesis of reports applying the Joanna Briggs quality assessment guidelines. Results A total of 44 articles meeting the criteria were included for final consideration. We conducted an integrative systematic review of 27 quantitative studies, narrative synthesis of 10 qualitative studies, and 7 psychosocial and behavioral health intervention studies. PH patients reported psychosocial needs, such as financial, social connections, sexual health, and palliative care needs, as well as levels of psychological distress symptoms. The results from both quantitative and qualitative studies revealed similar overarching psychosocial and behavioral health conceptual categories. Patients described their ongoing needs in PH management by relying on their psychosocial and behavioral health capabilities to adjust to changes at each stage of disease progression. Patients had high levels of psychosocial and behavioral health needs requiring interventions beyond medical treatment. Discussion Pilot studies testing psychosocial and behavioral health interventions reported improvement in levels of anxiety and depression and health-related quality of life. Larger scale studies are needed to advance this knowledge. Psychosocial and behavioral health interventions with cognitive-guided foci have the potential of meeting these unmet needs.
