RESUMO

BACKGROUND: Fear of cancer recurrence (FCR) is a multidimensional construct; however, few studies have meaningfully integrated FCR severity (i.e., level of fear) with FCR-related concepts (e.g., triggers). PURPOSE: The present study determined (a) latent profiles of FCR; (b) socio-demographic variations between identified profiles; (c) interactions between identified profiles and resilience and rumination on chronic physical disorders, depressive/anxiety symptoms, and quality of life. METHODS: The present study is a secondary data analysis of which 404 cancer survivors were included in this study. All participants completed the Fear of Cancer Recurrence Inventory and measures of resilience, rumination, depressive/anxiety symptoms, and quality of life. RESULTS: Latent profile analysis identified three distinct profiles based on varying levels of FCR and FCR-related concepts; Profile 1 "Low FCR" (n = 108; 26.4%), Profile 2 "Moderate FCR, High coping" (n = 197; 49.4%), and Profile 3 "High FCR, distress and impairment" (n = 99; 24.3%). Profile 3 was associated with younger age and history of radiotherapy. Latent profiles of FCR significantly interacted with resilience and rumination on depressive/anxiety symptoms. CONCLUSIONS: Latent profile analysis integrates FCR severity and FCR-related concepts to support a nuanced understanding of FCR. Our results suggest specific points of intervention, which extend beyond addressing FCR severity.


Fear of cancer recurrence (FCR) is a multidimensional construct comprising of both FCR severity (i.e., level of fear) and FCR-related concepts (e.g., triggers). The present study aimed to (a) identify underlying profiles of FCR; (b) determine their associations with socio-demographic variables; and (c) elucidate interactions between identified FCR profiles and resilience and rumination to predict depressive/anxiety symptoms, chronic physical disorders, and quality of life. The present study is a secondary data analysis of which 404 cancer survivors were included in this study. All participants completed the Fear of Cancer Recurrence Inventory and measures of resilience, rumination, depressive/anxiety symptoms, and quality of life. The present study identified three distinct profiles based on varying levels of FCR and FCR-related concepts; Profile 1 "Low FCR" (n = 108; 26.4%), Profile 2 "Moderate FCR, High coping" (n = 197; 49.4%), and Profile 3 "High FCR, distress and impairment" (n = 99; 24.3%). Profile 3 was associated with younger age and history of radiotherapy. FCR profiles significantly interacted with resilience and rumination to predict depressive/anxiety symptoms. The present study integrated FCR severity and FCR-related concepts to support a nuanced understanding of FCR. Our results suggest specific points of intervention, which extend beyond addressing FCR severity.

RESUMO

BACKGROUND: Physical performance declines and executive dysfunctions are predictors of dementia. However, their associations are not well understood in Asian older adults without dementia (cognitively normal [CN] and mild cognitive impairment [MCI]), especially in a single study. OBJECTIVE: Examine the associations between physical performance measures with executive function (EF)-based and non-EF-based neurocognitive tests and whether preclinical dementia cognitive status i.e., CN and MCI, moderated these associations. METHODS: We examined cross-sectional cohort of 716 community-dwelling older adults without dementia (CN = 562 and MCI = 154) using multivariable linear regression models. We associated three simple physical performance measures, namely timed-up-and-go (TUG), fast gait speed (FGS), and 30-s chair stand test (30 s-CST), with a comprehensive neurocognitive test battery measuring EF and non-EF cognitive functions. Moderating effects of cognitive status on the associations were examined. In all models, we controlled for pertinent covariates, including age, education, medical and psychiatric status. RESULTS: Upon controlling for covariates, TUG was most strongly and positively associated with multiple EF-based neurocognitive tests, followed by FGS, with 30 s-CST having the weakest associations. For all physical performance measures, no significant associations with non-EF-based neurocognitive tests were detected. Cognitive status significantly moderated the associations between all physical measures and several neurocognitive tests, with stronger associations in the MCI than CN. CONCLUSION: Compared to FGS and 30 s-CST, TUG had the most robust associations with multiple EF-based cognitive functions. Given their differential associations with global and detailed neurocognitive tests and significant moderating effects of cognitive status, findings highlight a need to carefully consider the choices of simple physical performance tests when using these tests with a heterogenous group of community-dwelling older adults without dementia.

RESUMO

OBJECTIVE: The COVID-19 lockdown could see older adults facing increased anxiety levels due to social isolation. Additionally, the lockdown could be more difficult for those with lower Quality of Life (QoL). We aim to understand predictive factors of older adult's anxiety symptoms during the lockdown as it is a main psychological concern of COVID-19. METHODS: Four hundred eleven participants (Mage = 68.95, S.D. = 5.60) completed questionnaires at two time points - before the pandemic and during the lockdown period. Cross-lagged analysis was carried out on two structural equation models - social isolation and anxiety symptoms, and QoL and anxiety symptoms. RESULTS: Baseline social isolation was associated with more anxiety symptoms at follow-up. However, baseline anxiety symptoms were not associated with social isolation subsequently. For QoL and anxiety symptoms, the relationship was bidirectional. CONCLUSION: Older adults who were previously socially isolated and had a lower QoL are particularly vulnerable to the negative psychological impacts of the COVID-19 lockdown.

RESUMO

OBJECTIVE: Previous research on art therapy (AT) in cognitive aging has been lacking. AT can potentially engender significant cognitive gains, due to its rigorous cognitive involvement, making it useful to tackle age-related cognitive decline. Along with these cognitive gains, associated neuroplastic changes are hypothesized to arise from AT as well. The current intervention examined the effects of an AT intervention on cognitive outcomes and cortical thickness (CT) among participants with mild cognitive impairment. METHOD: Participants were assigned to AT (n = 22) and an active control group (n = 27). In both, weekly 45-min sessions were carried out across 3 months. Cognitive assessments and structural magnetic resonance imaging scans were carried out at baseline and 3-month follow-up. Whole brain analyses on CT were carried out. Cognitive outcomes were analyzed using hierarchical linear models. RESULTS: Significant gains in immediate memory and working memory span were observed in the AT group, relative to the control group. Significantly increased CT in the AT group, relative to controls, was observed in a right middle frontal gyrus (MFG) cluster. Furthermore, CT changes in this cluster were significantly and positively correlated with changes in immediate memory. CONCLUSION: These findings highlighted the role of MFG neuroplasticity in enhancing certain cognitive functions in AT. AT is a neuroplastic intervention capable of engendering significant cognitive gains and associated cortical changes in the context of age-related cognitive decline, even when executed as a low-intensity intervention across 3 months. Given the preliminary nature of these findings, future larger sampled studies are needed.

RESUMO

BACKGROUND: The COVID-19 pandemic has changed our daily lives. Most of the working adults adopted the work-from-home arrangement while students shifted to home-based learning. Being confined together allows families to foster stronger bonds. On the other hand, the on-going pandemic could have negative impacts on family relationships. The COVID-19 outbreak is still on-going worldwide, understanding more about the changes in family functioning and its associated psychological impacts in a pandemic would allow the authorities to provide more targeted support to families. OBJECTIVES: This study aimed to examine the factors associated with family functioning among young adults in Singapore during the COVID-19 pandemic. Family functioning refers to the quality of interactions among family members, and consists of cohesion, flexibility and communication. METHODS: A cross-sectional online survey was conducted (N = 390). The Family Adaptability and Cohesion Evaluation Scale Short Form (FACES-IV-SF) and Global Perceptions of Intergenerational Communication Scale (GPIC) were used to examine family functioning and intergeneration communication during the partial lockdown. Center for Epidemiologic Studies Depression Scale (CESD), Social Support Questionnaire-Brief (SSQ-B), Perceived Stress Scale 4 (PSS), UCLA Loneliness Scale, and Brief Resilient Coping Scale (BRCS) examined the psychosocial impact. Descriptive statistics, Pearson's correlation coefficients, and regression model were employed in the analysis. RESULTS: The FACES-IV-SF score for total circumplex ratio has a mean of 1.57(SD = 0.58), suggesting that participants generally perceived their families as functioning relatively well. The mean scores for CESD, PSS, Loneliness and BRCS were 12.4(6.2), 8.0(2.6), 5.7(1.9) and 12.6(3.1) respectively. The mean scores of the 4 domains of GPIC were 21.5(4.0) for Accommodation, 25.0(6.7) for Non-Accommodation, 17.2(3.3) for Respect-Obligation, and 18.9(4.8) for Avoidant. CONCLUSION: The results suggested that family functioning is significantly associated with intergenerational communication and satisfaction with social support in a pandemic. Participants with balanced levels of cohesion and flexibility in their families are more likely to be able to cope with the psychological impacts of the pandemic. The findings serve to inform intervention and preventive efforts to improve family functioning and reduce the risk of psychological distress in a pandemic.

RESUMO

Cumulative lifetime trauma has a profound impact on the development of schizophrenia spectrum disorders. However, few studies have determined participants' most distressing (i.e., "worst") life event in childhood or adulthood or examined whether this event contributes to poorer clinical outcomes. The present study aimed to (a) determine the associations between the worst life event and demographic/clinical variables and (b) examine the associations between the worst life event and psychiatric symptoms (i.e., positive, negative, depressive, and anxiety symptoms). Participants (N = 150) were outpatients newly diagnosed with schizophrenia spectrum disorders who were assessed for lifetime trauma exposure, positive and negative symptoms of schizophrenia, and symptoms of depression and anxiety. Multinomial logistic regression analysis was conducted to examine the associations between demographic and clinical variables and worst life events (none, childhood, or adulthood). Multiple linear regression analyses were performed to examine the associations between worst life events and psychiatric symptoms. More participants reported that their worst life event occurred during adulthood (31.1%) than childhood (21.3%). Adulthood trauma was associated with male gender, older age, non-Chinese ethnicity, and psychiatric comorbidities; childhood trauma was associated with a family history of depression/anxiety. Adulthood trauma was significantly associated with more severe positive psychotic symptoms, f2 = 0.19, whereas childhood and adulthood trauma exposure were both significantly associated with more severe depressive and anxiety symptoms, f2 s = 0.19 and 0.25, respectively. Our findings underscore the importance of conducting assessments for worst life events and the associated risk factors to develop meaningful formulations and appropriate trauma-focused treatment plans.

RESUMO

OBJECTIVES: As the global burden of dementia rises, the search for preventive measures such as interventions for mild cognitive impairment (MCI) remains a research priority. While arts-based interventions have demonstrated some success in improving cognitive functioning among older adults and those with dementia, its effectiveness for older persons with MCI remains unexplored. We conducted a systematic review to examine the effects of arts-based interventions on cognition in older persons with MCI. METHOD: The following databases were searched in November 2019: PubMed, EMBASE, PsycINFO, and CINAHL Plus, supplemented by Google Scholar and ALOIS. Study inclusion criteria were older persons aged ≥ 60 with MCI; arts-based interventions such as dance, drama, music, or visual arts; and randomized controlled trial with cognitive outcome. Database search, study selection, and data extraction were conducted independently by 2 reviewers. RESULTS: Eleven randomized controlled trials examining 13 interventions (817 participants) were identified, of which 4 involved visual arts, 4 dance/movement, 3 music, and 2 storytelling. Significant improvement on at least one cognitive outcome was reported in 10 of the 13 interventions. These included improvements in global cognition (6/7 interventions), learning and memory (5/9), complex attention (4/10), executive functioning (2/6), language (2/3), and perceptual-motor function (1/4). CONCLUSION: This review found that arts-based interventions can potentially improve various aspects of cognitive functioning in older persons with MCI, although our confidence was dampened by methodological limitations such as the moderate-to-high risk of bias present in studies and heterogeneity in the way MCI was defined. Recommendations for future research are discussed.

RESUMO

Neuropsychological assessments are essential in diagnosing age-related neurocognitive disorders. However, they are lengthy in duration and can be unreliable at times. To this end, we explored a modified connectome-based predictive modeling approach to estimating individualized scores from multiple cognitive domains using structural connectivity (SC) and functional connectivity (FC) features. Multi-shell HARDI and resting-state functional magnetic resonance imaging scans, and scores from 10 cognitive measures were acquired from 91 older adults with mild cognitive impairment. SC and FC matrices were derived from these scans and, in various combinations, entered into models along with demographic covariates to predict cognitive scores. Leave-one-out cross-validation was performed. Predictive accuracy was assessed via the correlation between predicted and observed scores (rpredicted-observed). Across all cognitive measures, significant rpredicted-observed (0.402 to 0.654) were observed from the best-predicting models. Six of these models consisted of multimodal features. For three cognitive measures, their best-predicting models' rpredicted-observed were similar to that of a model that included only demographic covariates- suggesting that SC and/or FC features did not contribute significantly on top of demographics. Cross-prediction models revealed that the best-predicting models were similarly accurate in predicting scores of related cognitive measures- suggesting their limited specificity in predicting cognitive scores. Generally, multimodal connectomes together with demographics, can be exploited as sensitive markers, though with limited specificity, to predict cognitive performance across a spectrum in multiple cognitive domains. In certain situations, it may not be worthwhile to acquire neuroimaging data, considering that demographics alone can be similarly accurate in predicting cognitive scores.

RESUMO

BACKGROUND: Geriatric depression is a growing public health issue worldwide. This study aims at identifying the relevant neighbourhood attributes, separate from the individual-level characteristics, that are related to the onset of depressive disorders among the geriatric population. METHODS: This study adopts a structural equation modelling (SEM) approach to understand the effect of the neighbourhood environment on geriatric depression, as identified by data collected from community-dwelling elderly living in Hong Kong and Singapore. Using network buffers as the unit of analysis, different features of the neighbourhood environment are captured and analysed. SEM also examines the strength and direction of the relationships using different parameters at both the individual and neighbourhood levels, as well as the prevalence of depressive symptoms among the elderly. RESULTS: The total sample size is 347, with 173 and 174 elderly people in Hong Kong and Singapore respectively. The results show that in addition to one's physical health status, both objective and subjective neighbourhood factors including the size of parks, land use mix, walkability, and connectivity are all statistically significant influential factors in geriatric depression. In particular, enhancing walkability and providing more parks at the neighbourhood level can bring mental health benefits. CONCLUSIONS: Public health policy initiatives aimed at tackling geriatric depression can be achieved by adopting a holistic and integrative approach to better prepare the neighbourhood environment in an ageing society.

RESUMO

BACKGROUND: Dementia is a global epidemic and incurs substantial burden on the affected families and the health care system. A window of opportunity for intervention is the predementia stage known as mild cognitive impairment (MCI). Individuals often present to services late in the course of their disease and more needs to be done for early detection; sensor technology is a potential method for detection. OBJECTIVE: The aim of this cross-sectional study was to establish the feasibility and acceptability of utilizing sensors in the homes of senior citizens to detect changes in behaviors unobtrusively. METHODS: We recruited 59 community-dwelling seniors (aged >65 years who live alone) with and without MCI and observed them over the course of 2 months. The frequency of forgetfulness was monitored by tagging personal items and tracking missed doses of medication. Activities such as step count, time spent away from home, television use, sleep duration, and quality were tracked with passive infrared motion sensors, smart plugs, bed sensors, and a wearable activity band. Measures of cognition, depression, sleep, and social connectedness were also administered. RESULTS: Of the 49 participants who completed the study, 28 had MCI and 21 had healthy cognition (HC). Frequencies of various sensor-derived behavior metrics were computed and compared between MCI and HC groups. MCI participants were less active than their HC counterparts and had more sleep interruptions per night. MCI participants had forgotten their medications more times per month compared with HC participants. The sensor system was acceptable to over 80% (40/49) of study participants, with many requesting for permanent installation of the system. CONCLUSIONS: We demonstrated that it was both feasible and acceptable to set up these sensors in the community and unobtrusively collect data. Further studies evaluating such digital biomarkers in the homes in the community are needed to improve the ecological validity of sensor technology. We need to refine the system to yield more clinically impactful information.

RESUMO

AIM: There is increasing evidence that mild cognitive impairment (MCI) is associated with widespread brain dysconnectivity. Mindfulness practice, which involves focused attention to experience the present moment in a purposeful way, has been shown to confer positive psychological and functional brain changes in healthy practitioners. It is unclear whether mindfulness practice could improve functional brain connectivity in older adults with cognitive impairment. METHODS: Forty-seven participants with MCI were randomized into two groups: a mindfulness practice group and a control group. Functional magnetic resonance imaging of the brain and neurocognitive tests were performed before and after the 3-month intervention. A temporal efficiency analysis approach was used to examine the spatiotemporal networks of the brain. RESULTS: Participants in the mindfulness group had significantly better temporal global efficiency than controls after 3-months of intervention. Localized changes of temporal nodal properties were present in the right cingulate gyrus, insula, and left superior temporal gyrus. Together, these results suggest greater information transmission efficiency at both the global and local spatiotemporal level. In terms of cognitive function, verbal recognition memory improved in the mindfulness group compared to the controls. CONCLUSION: Elders who practiced mindfulness had better brain network efficiency and neurocognitive function relative to controls in this study, suggesting that mindfulness may be of benefit to aging adults with early cognitive degeneration.

RESUMO

PURPOSE: The cancer caregiving experience is multifaceted and dynamic across different phases of the cancer care continuum. This longitudinal study examined the trajectories of CQOL and caregiver emotional distress across the first year post-diagnosis. METHODS: Participants were 111 caregivers of newly diagnosed patients who completed baseline, 6-month, and 12-month follow-ups. Trajectories of CQOL, CQOL domains, caregiver depression, anxiety, and stress, were estimated using linear and quadratic mixed models. RESULTS: The trajectory of overall CQOL followed an inverse U-shape trend, while caregiver depression, anxiety, and stress remained stable. For CQOL domains, physical/practical needs followed a gradual trend of improvement, while social support followed an inverse U-shape trend; caregiver burden, emotional reactivity, and responsibility/duty remained stable. CONCLUSIONS: The multidimensional needs of caregivers of newly diagnosed patients appeared to follow different trajectories across the first year post-diagnosis. While most CQOL domains remained stable, caregivers may experience adjustment difficulties in terms of relational concerns and social support.

RESUMO

OBJECTIVES: Accumulating research evidence supports the role of emotion dysregulation in the etiology of schizophrenia spectrum disorders. The present systematic review synthesized the extant literature and aimed to determine the effects of cognitive emotion regulation strategies and global emotion dysregulation on positive and negative symptoms in schizophrenia spectrum disorders. METHOD: A comprehensive systematic review was conducted to identify quantitative studies published between 2000 and 2019. A total of 22 studies were included in this review. RESULTS: Overall, maladaptive cognitive emotion regulation strategies of rumination, worry, and suppression were generally related to more positive symptoms, while global emotion dysregulation was related to more positive and negative symptoms. CONCLUSIONS: Our results provide preliminary and conceptual evidence on the role of emotion dysregulation in understanding schizophrenia spectrum disorders. Psychological treatment should further determine the therapeutic value of addressing emotion dysregulation to improve positive and negative symptoms in schizophrenia spectrum disorders.

RESUMO

Previous studies have identified a positive association between maladaptive cognitive emotion regulation strategies and positive symptoms (e.g., hallucinations and delusions) among patients with schizophrenia spectrum disorders. However, translating this finding to clinical practice is challenging. Some patients are reported to experience difficulties in correcting the use of maladaptive cognitive emotion regulation strategies in psychological therapy, which may be due to an underlying effect of global emotion dysregulation. Therefore, the present study aimed to determine the mediating or moderating role of global emotion dysregulation in the relationship between maladaptive cognitive emotion regulation strategies and positive symptoms. A total of 123 newly diagnosed patients with schizophrenia spectrum disorders completed self-report measures of maladaptive cognitive emotion regulation strategies (rumination, catastrophic thinking, self-blame, other-blame) and global emotion dysregulation. The severity of positive symptoms was rated on the Brief Psychiatric Rating Scale-Expanded. Mediation and moderation analyses were performed to test the hypothesized models. Mediation analysis revealed that global emotion dysregulation mediated the relationship between maladaptive cognitive emotion regulation strategies and positive symptoms after controlling for age, gender, ethnicity, duration of untreated psychosis, medication dosage, psychiatric comorbidities, and family history of mental illness (R2 = 23.3%, moderate effect size = 0.30). There was no moderating effect of global emotion dysregulation. The present study presents preliminary evidence on the mediating role of global emotion dysregulation in the relationship between maladaptive cognitive emotion regulation strategies and positive symptoms in schizophrenia spectrum disorders. This finding adds to our current understanding on emotion regulation phenomena in schizophrenia spectrum disorders.

RESUMO

AIM: Dementia is a growing public health concern. It is necessary to focus on factors that may help preserve cognitive function in late life. Limited research has examined how living arrangements are associated with cognitive function in older adults. This study aims to further our understanding of this association in community-dwelling older adults in a multi-ethnic Asian population. METHODS: Data were obtained from a cross-sectional population survey of 2548 adults aged 60 and older with standardized instruments. Living arrangements were classified as living with adult children and grandchildren, living with adult children only, living with a spouse/partner only, living alone, living with other relatives, and living with non-relatives. RESULTS: Cognitive function was significantly predicted by living arrangements among community-dwelling older adults. Multivariate linear regression analyses revealed that older adults in multigenerational family households had significantly poorer cognitive function than those living with a spouse/partner (ß = 0.54, P < 0.02) and those living with non-relatives (ß = 1.08, P < 0.02). This association was independent of the influence of age, gender, ethnicity, education, employment status, marital status, depression, disability, chronic health conditions, and self-reported health. CONCLUSION: Older adults living in multigenerational households seem to be disadvantaged in their cognitive function. However, we cannot conclude this based on the evidence because of the cross-sectional nature of the data. Further research is needed to reasonably determine the relationship between living arrangements and cognitive function. Regardless, these findings add to the growing understanding of the complex relationship between living arrangements and cognition in older adults and could provide a basis to design effective strategies to delay cognitive decline in community-dwelling older adults.

RESUMO

BACKGROUND: We aimed to examine the discriminant validity of a brief self-administered cognitive screening test, the Test Your Memory (TYM) and a brief neuropsychological test, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), supplemented with executive and language tests (Color Trail Test [CTT] and modified Boston Naming Test [mBNT], respectively), in detecting cognitive impairment (CI) in a one-stop memory clinic in Singapore. METHODS: Ninety patients ≥50 years old with a diagnosis of no cognitive impairment, mild cognitive impairment, and mild Alzheimer disease were recruited from memory clinic. They received the TYM, Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), RBANS, CTT, mBNT, and a gold-standard formal neuropsychological test battery. RESULTS: The TYM had a significantly larger area under the curve (AUC) than MMSE (0.96 vs 0.88, P = .03) and was equivalent to MoCA in detecting CI (0.96 vs 0.95, P = .80). At the optimal cutoff points, the TYM (<38) was significantly more sensitive than the MMSE (<24) and MoCA (<20; P < .001). The RBANS had an AUC equivalent to the RBANS supplemented with CTT and mBNT (0.92 vs 0.86, P = .22) in detecting CI. The RBANS supplemented with CTT and mBNT was more sensitive than RBANS alone in detecting CI (sensitivity: 0.98 vs 0.93, P = .016) among patients screened negative using TYM. CONCLUSION: The self-administered TYM is superior to MMSE and equivalent to MoCA in detecting CI and could be implemented routinely. The RBANS supplemented with CTT and mBNT is more sensitive in detecting CI than RBANS alone therefore could be used for diagnostic purposes.

RESUMO

ABSTRACTBackground:Little is known about the combined use of benzodiazepines and antidepressants in older psychiatric patients. This study examined the prescription pattern of concurrent benzodiazepines in older adults treated with antidepressants in Asia, and explored its demographic and clinical correlates. METHODS: The data of 955 older adults with any type of psychiatric disorders were extracted from the database of the Research on Asian Psychotropic Prescription Patterns for Antidepressants (REAP-AD) project. Demographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. Both univariate and multiple logistic regression analyses were performed. RESULTS: The proportion of benzodiazepine and antidepressant combination in this cohort was 44.3%. Multiple logistic regression analysis revealed that higher doses of antidepressants, younger age (<65 years), inpatients, public hospital, major comorbid medical conditions, antidepressant types, and country/territory were significantly associated with more frequent co-prescription of benzodiazepines and antidepressants. CONCLUSIONS: Nearly, half of the older adults treated with antidepressants in Asia are prescribed concurrent benzodiazepines. Given the potentially adverse effects of benzodiazepines, the rationale of benzodiazepines and antidepressants co-prescription needs to be revisited.

RESUMO

BACKGROUND: A shortage of specialists in psychiatry, both in terms of psychiatrists and psychiatric nurses is evident worldwide. While there are multiple factors leading to an individual's decision to specialize in psychiatry, the individual's perceptions and attitudes towards psychiatry tend to play an essential role. This study thus aimed to explore attitudes towards psychiatry amongst medical and nursing students in Singapore and examine factors associated with these attitudes. METHODS: The present cross-sectional study used an online web survey tool to assess attitudes towards psychiatry amongst 502 medical and 500 nursing students in Singapore using the Attitudes towards Psychiatry (ATP-18) scale. Descriptive statistics and multiple linear regressions were used to examine associated factors (sociodemographic and education). RESULTS: The majority of students in this population endorsed favourable attitudes towards the following aspects of psychiatry: challenges within psychiatry, importance of psychiatry and psychiatric skills, treatment efficacy and view towards psychiatrists, but had generally unfavourable attitudes towards psychiatric patients. Male participants (compared to female; ß = - 1.190, p < 0.05), participants in the middle income group (compared to higher income group; ß = - 0.945, p < 0.05), participants who rated average for psychiatry lecture course and psychiatry clinical placement course (compared to above average; ß = - 1.654, p < 0.05; ß = - 1.181, p < 0.05) had a less favourable attitude to psychiatry. Not surprisingly, participants who were more likely to specialize in psychiatry (ß = 2.053, p < 0.001) had a more favourable attitude towards psychiatry compared to those who were less likely to specialize in psychiatry. CONCLUSIONS: The majority of students in this study endorsed unfavourable attitudes towards patients in the psychiatric setting. The present psychiatry curriculum could be improved to nurture the development of empathetic attitudes towards people with mental illness. De-stigmatization strategies could also be integrated into other curricula besides psychiatry.

RESUMO

AIM: Depressive disorders are common in old age. Antipsychotics (APs) are often used as an adjunctive treatment with antidepressants (ADs) in this population but its patterns of use in Asia are not known. This study explored the rate of combination of APs and ADs in older adult psychiatric patients in Asia. METHODS: This is a secondary analysis of the database of a multicentre study which recorded participants' basic demographical and clinical data in standardised format in 10 Asian countries and territories. The data were analysed using univariate and multivariate logistic regression analyses. RESULTS: A total of 955 older adult psychiatric in- and outpatients were included in this study. The proportion of concurrent AP and AD use was 32.0%, ranging from 23.3% in Korea to 44.0% in Taiwan. Multivariate logistic regression analysis found that younger age, inpatient status and diagnosis of schizophrenia, anxiety and other mental disorders were significantly related to a higher proportion of concurrent use of APs and ADs. CONCLUSION: Around a third of older adult psychiatric patients had concurrent AP and AD use in the Asian countries/regions surveyed. Considering the uncertain effectiveness and questionable safety of the AP and AD combination in this patient population, such should be cautiously used.

RESUMO

BACKGROUND: Previous cross-lagged studies on depression and memory impairment among the elderly have revealed conflicting findings relating to the direction of influence between depression and memory impairment. The current study aims to clarify this direction of influence by examining the cross-lagged relationships between memory impairment and depression in an Asian sample of elderly community dwellers, as well as synthesizing previous relevant cross-lagged findings via a meta-analysis. METHODS: A total of 160 participants (Mage = 68.14, s.d. = 5.34) were assessed across two time points (average of 1.9 years apart) on measures of memory and depressive symptoms. The data were then fitted to a structural equation model to examine two cross-lagged effects (i.e. depressive symptoms→memory; memory→depressive symptoms). A total of 14 effect-sizes for each of the two cross-lagged directions were extracted from six studies (including the present; total N = 8324). These effects were then meta-analyzed using a three-level mixed effects model. RESULTS: In the current sample, lower memory ability at baseline was associated with worse depressive symptoms levels at follow-up, after controlling for baseline depressive symptoms. However, the reverse effect was not significant; baseline depressive symptoms did not predict subsequent memory ability after controlling for baseline memory. The results of the meta-analysis revealed the same pattern of relationship between memory and depressive symptoms. CONCLUSIONS: These results provide robust evidence that the relationship between memory impairment and depressive symptoms is unidirectional; memory impairment predicts subsequent depressive symptoms but not vice-versa. The implications of these findings are discussed.
