Effect of loneliness on social exclusion among older adults
Loneliness is a significant issue among older adults. However, few studies have explored the brain mechanisms underlying changes in social behavior related to loneliness among older adults. Therefore, this study aimed to examine how loneliness affects the response towards social exclusion among community-dwelling older people. The sample consisted of 37 older adults who made up the lonely (n = 21) and not-lonely control (n = 16) groups based on t…
Stigma and health inequality experienced by ethnic minorities during the Covid-19 pandemic in a Chinese community
Introduction: Ethnic minorities are considered one of the most vulnerable groups during the COVID-19 pandemic. However, the explanatory pathway of how their disadvantaged experiences during epidemics are related to the embedded and longstanding stigmas against them and how these embedded stigmas can affect their resilience in disease outbreaks are not well understood. This study investigated the experiences of ethnic minorities in the COVID-19 pa…
A pattern‐centered analysis of adolescents' concerns and hopes about future crises
INTRODUCTION: Many adolescents are concerned about global and future crises, such as the health of the planet or terrorism/safety. Yet, adolescents can also express hope about the future. Thus, asking adolescents about their concern and hope could yield subgroups with different ways of coping and personal adjustment. METHOD: Australian adolescents (N = 863; age 10-16) completed surveys to report their concern (worry and anger) and hope about the …
Post-traumatic stress disorder (PTSD) after an earthquake experience
Natural disasters such as earthquakes are highly associated with post-traumatic stress disorder (PTSD). The Wenchuan earthquake in 2008 was the worst earthquake in the modern history of China, but the long-term prevalence of PTSD among earthquake victims, particularly those with disabilities, remains unknown. This study investigated the long-term effect of PTSD brought about by the Wenchuan earthquake, and its relationship with demographic factor…
Measuring Engagement in Antisocial Behavior During Late Adolescence and Early Adulthood for Typically Developing Youth
Mind wandering in schizophrenia
Mind wandering has consistently been associated with impairments in cognition, emotion and daily performance. However, few experimental studies on mind wandering have been conducted in individuals with schizophrenia. The present study aimed to examine mind wandering in schizophrenia patients with a thought-sampling experiment embedded in a rapid go/no-go task and the relationship between the frequency of mind wandering and psychotic symptoms. Fif…
Effectiveness of Sensory Modulation in Treating Sensory Modulation Disorders in Adults with Schizophrenia
Cross-cultural validation of the Depression Anxiety Stress Scale–21 in China.
The gap between the demand and delivery of mental health services in mainland China can be reduced by validating freely available and psychometrically sound psychological instruments. The present research examined the Chinese version of the 21-item Depression Anxiety Stress Scales (DASS-21). Study 1 administered the DASS-21 to 1,815 Chinese college students and found internal consistency indices (Cronbach's alpha) of .83, .80, and .82 for the Dep…
Devaluation of Rewards for the Future Is Associated With Schizotypal Personality Features
ObjectiveEmpirical evidence has suggested that schizophrenia is associated with dysfunctions in the reward system and working memory. However, little is known about individuals at risk for schizophrenia. In particular, it is not known if those with schizotypal personality features will show similar deficits in these two domains. This study examined whether individuals with schizotypal personality disorder features will subjectively devalue potent…
World Trends in Psychological Research Output and Impact
Research output and impact are important indices of the health of individual fields of science. The present study analyzed publications and citations in psychology recorded in Web of Science for the years 1996 to 2010 for 73 countries, and the association of output with indices of national development. Authors with affiliations to institutions in the United States or Western Europe were the major contributors over the period, with output and impa…

The Australian Remote Memory Battery, 10 Years on
The article reviews research conducted with the Australian Remote Memory Test (ARMB) since its development first reported in 2001. Data from case studies and experimental investigations that have used the ARMB are summarised, and the use made of these data in reviews of the literature is noted. The ARMB has been found sensitive to disease processes such as herpes simplex, stroke, and epilepsy and lesion effects such as temporal lobectomy. The pat…
Neuropsychological Measures of Executive Function and Antisocial Behavior
A meta-analysis was performed to quantify the association between antisocial behavior (ASB) and performance on neuropsychological executive functioning (EF) measures. This meta-analysis built on Morgan and Lilienfeld's (2000) meta-analysis of the same topic by including recently published studies and by examining a wider range of EF measures. A total of 126 studies involving 14,786 participants were included in the analyses. Antisocial groups per…
Development of a music intervention protocol and its effect on participant engagement
Objectives: Develop and implement a music intervention protocol for use with older people with dementia and explore its effect on engagement. Design: A randomised cross-over trial with music intervention and reading control groups. Methods: A music protocol was developed through research team expertise, discussions with facility staff and musicians, practice session feedback and participants' musical preferences. A participant engagement observat…
A Randomized Controlled Trial Exploring the Effect of Music on Quality of Life and Depression in Older People with Dementia
This randomized controlled trial investigated the effect of live music on quality of life and depression in 47 older people with dementia using the Dementia Quality of Life and Geriatric Depression Scale. The control/reading group reported higher mid-point feelings of belonging than the music group ( F(1, 45) = 6.672, p < .05). Sub-analyses of ≥ 50 per cent music session attendance found improvements in self-esteem over time ( F(2, 46) = 4.471, p…
Assessment of executive functions
"Executive functions" is an umbrella term for functions such as planning, working memory, inhibition, mental flexibility, as well as the initiation and monitoring of action. The impairment of executive functions in various clinical groups is a topic of much debate, as are recent attempts to formulate the corresponding intervention and rehabilitation regimes of these dysfunctions. This article reviewed current theories of executive functions and t…
The development of picture cards and their use in ascertaining characteristics of Chinese surgical patients’ decision‐making preferences
Aim This exploratory pilot study developed and tested the validity of picture cards as a strategy to ascertain patients’ desired participation in decision making. These were then used to ascertain characteristics of Hong Kong Chinese patients’ decision‐making preferences for surgery. Validation of tool Two sets of analyses tested the validity of picture cards in an Australian and Hong Kong Chinese population. First, the ratings of the two groups …
