This study investigated trajectories of psychological distress and their relationships with change in psychosocial resources in the year following cancer diagnosis. Chinese colorectal cancer (CRC) patients (n = 234) were assessed within 12 weeks of diagnosis (T1) and again at 3-month (T2) and 12-month (T3) follow-ups. Growth mixture modeling was used to analyze the longitudinal data. Psychological distress was measured at the three time-points using Hospital Anxiety and Depression Scale (HADS). Growth mixture models identified four classes: chronic distress (7-9%), delayed distress (10-13%), recovery (13-16%), and resilient (65-67%). People in chronic distress were more likely to demonstrate loss in physical functioning and social relational quality than those in delayed distress, and loss in physical functioning, optimism, and hope than those in recovery, but more likely to demonstrate stability/gain in optimistic personalities than those in delayed distress and resilient. People in resilient were more likely to report stability/gain in optimistic personalities than those in delayed distress but not those in recovery. Understanding differential outcome trajectories and associated change in coping resources has implications for developing ongoing psychological services for cancer patients during the diagnosis and treatment process.

This study examined the dissociable neural effects of ānāpānasati (focused-attention meditation, FAM) and mettā (loving-kindness meditation, LKM) on BOLD signals during cognitive (continuous performance test, CPT) and affective (emotion-processing task, EPT, in which participants viewed affective pictures) processing. Twenty-two male Chinese expert meditators (11 FAM experts, 11 LKM experts) and 22 male Chinese novice meditators (11 FAM novices, 11 LKM novices) had their brain activity monitored by a 3T MRI scanner while performing the cognitive and affective tasks in both meditation and baseline states. We examined the interaction between state (meditation vs. baseline) and expertise (expert vs. novice) separately during LKM and FAM, using a conjunction approach to reveal common regions sensitive to the expert meditative state. Additionally, exclusive masking techniques revealed distinct interactions between state and group during LKM and FAM. Specifically, we demonstrated that the practice of FAM was associated with expertise-related behavioral improvements and neural activation differences in attention task performance. However, the effect of state LKM meditation did not carry over to attention task performance. On the other hand, both FAM and LKM practice appeared to affect the neural responses to affective pictures. For viewing sad faces, the regions activated for FAM practitioners were consistent with attention-related processing; whereas responses of LKM experts to sad pictures were more in line with differentiating emotional contagion from compassion/emotional regulation processes. Our findings provide the first report of distinct neural activity associated with forms of meditation during sustained attention and emotion processing.

Purpose To examine the joint associations of civil unrest and COVID-19 with probable anxiety and depression during the first half of 2020 in Hong Kong. Associations were compared between persons with low or high assets. Methods A population-representative sample of 4011 Hong Kong Chinese residents aged 15 years or older were recruited between February and May 2020. Respondents reported current anxiety and depressive symptoms, unrest stress, COVID-19 stress, assets (savings and home ownership), and demographics. Results Stress due to unrest and COVID-19 was associated with higher prevalence of probable anxiety and depression; persons with both stressors had higher prevalence. This pattern was consistent among persons with low or high assets, but the probabilities of mental disorder were substantially higher among persons with fewer assets. Conclusions The effect of stressors on probable anxiety and depression are cumulative: persons with stress due to civil unrest and to COVID-19 reported more mental disorders than persons with stress due to only one, or none of these factors. Overall high assets appear to buffer the consequences of stressors, lowering the risk of mental disorder.
