“…Further, most studies showed comparable results investigating multidimensional associations of the QUALI-DEM subscales [25][26][27][28][29][30]. Moreover, in our study, we did not find significant outcomes regarding gender, age, FAST, and Barthel Index, which contradicts findings from the literature [42,43]. Thus, more research is needed to examine the association of momentary QoL and other indicators of health and functioning.…”

Purpose Our aim was to examine whether quality of life which was repeatedly assessed over time is related with the comprehensive assessment of quality of life (QoL) and thereby to validate a brief QoL assessment. Method This longitudinal study used a comprehensive assessment of quality of life at baseline (QUALIDEM; 37 items) to validate an eight-item version of QUALIDEM to assess momentary quality of life which was repeatedly administered using a tablet device after baseline. In all, 150 people with dementia from 10 long-term facilities participated. Momentary quality of life and comprehensive quality of life, age, gender, activities of daily living (Barthel Index), Functional assessment staging (FAST), and Geriatric Depression (GDS) have been assessed. Results Comprehensive and momentary quality of life showed good internal consistency with Cronbach's alpha of .86 and .88 to .93, respectively. For multiple associations of momentary quality of life with the comprehensive quality of life, momentary quality of life was significantly related to comprehensive quality of life (B = .14, CI .08/.20) and GDS (B = − .13, CI − .19/− .06). More specifically, the comprehensive QUALIDEM subscales 'positive affect', 'negative affect', 'restlessness', and 'social relationships' showed significant positive associations with momentary quality of life (p < .001). Conclusion We found that momentary quality of life, reliably assessed by tablet, was associated with comprehensive measures of quality of life and depressive symptoms in people with dementia. Broader use of tablet-based assessments within frequent QoL measurements may enhance time management of nursing staff and may improve the care quality and communication between staff and people with dementia.

Purpose Social support (SS) has been shown to moderate the relationship between psychological distress and physical activity (PA) in adults, including those with no history of cancer and cancer survivors (CS). The purpose of this study was to explore the relationship between stress and leisure‐time PA and test if SS is a moderator of this relationship in rural CS. Methods CS were recruited to Partnering to Prevent and Control Cancer (PPCC) and completed questionnaires assessing sociodemographics, leisure‐time PA, perceived stress, and SS. Hierarchical multivariable linear regression was used to assess the moderating role of SS on the association between stress and PA. Findings Cancer survivors (N = 219) were in their mid‐60s (M age = 64.3 ± 12.5 years) and overweight/obese (M BMI = 29.5 ± 6.8 kg/m2); over half were women (60.7%) and insufficiently active (59.4%); and 42.1% reported moderate‐to‐high perceived stress. Perceived stress was negatively correlated with PA (r = –.183, P = .044) and SS (r = –.470, P < .001), and SS was positively correlated with PA (r = .205, P = .025). However, SS did not moderate the association between stress and PA. Conclusions Rural CS reported higher stress and less PA than previously reported by urban CS, potentially contributing to rural cancer health disparities. Although previous studies have shown success in building SS to reduce stress and promote PA in CS, our results do not support the stress‐buffering hypothesis in rural cancer survivors. Further research is needed to understand factors related to PA in rural CS and determine strategies to reduce psychological distress and promote healthy behaviors in an effort to improve cancer survivorship.

“…Higher social support (especially from caregivers) has been found to be protective against mental health difficulties among ALHIV (Gentz et al, 2017) and for suicidal behaviours among youth in high-income countries; this includes evidence from longitudinal studies (McKinnon et al, 2016;Teismann et al, 2016). Social support can impact these psychological outcomes either by means of a direct effect, or by buffering the negative effects of specific stressors on these outcomes (Alloway and Bebbington, 1987;Casale et al, 2015a;Gellert et al, 2018). While multiple studies show direct protective effects of social support on depression and suicide among people living with HIV (Bitew et al, 2016;Brandt, 2009;Gentz et al, 2017), the evidence for stress-buffering is mixed: some studies have found social support to moderate effects of HIV-related stressors, such as financial stress or HIV-illness, on mental health outcomes (Robbins et al, 2003;Wight et al, 2003), while others did not find stressbuffering effects for HIV-related stigma (Breet et al, 2014;Rueda et al, 2012).…”

Background: Adolescents living with HIV represent a high-risk population for suicidal ideation and attempts, especially in low-income settings. Yet little is known about risk and protective factors for suicide in this population. Methods: A moderated mediation model was employed to test for potential (a) effects of stigma on suicidal ideation and attempts, both direct and mediated through depression and (b) direct and stress-buffering effects of social support resources on depression and suicidal ideation and attempts, among 1053 HIV-positive 10-19-year-old adolescents from a resource-scarce health district in South Africa. The survey data was collected using full community sampling of 53 clinics and tracing to over 180 communities. Effects of two support resources were tested: perceived support availability from the adolescents' social network and structured clinic support groups. Stigma was measured using the ALHIV-SS scale, depression through the CDI short form and social support through items from the MOS-SS. Results: Stigma was a risk factor for depression (B = 0.295; p < 001) and for suicidal thoughts and behaviour (B = 0.185; p < .001). Only perceived support availability was directly associated with less depression (B = −0.182, p < .001). However, both perceived support availability and support group participation contributed to the overall stress-buffering effects moderating the direct and indirect relationships between stigma and suicidal thoughts and behaviour. Limitations: The data used in this study was self-reported and cross-sectional. Conclusions: Findings suggest that strengthening multiple social support resources for HIVpositive adolescents, through early clinic and community-based interventions, may protect them from experiencing poor mental health and suicidal tendencies.
