Burnout is an important public health issue at times of the COVID-19 pandemic. Current measures which focus on work-based burnout have limitations in length and/or relevance. When stepping into the post-pandemic as a new Norm Era, the burnout scale for the general population is urgently needed to fill the gap.

Background: Identifying individuals at risk for falls during inpatient stroke rehabilitation can ensure timely implementation of falls prevention strategies to minimize the negative personal and health system consequences of falls.

Objectives: To compare sociodemographic and clinical characteristics of fallers and non-fallers; and evaluate the ability of the Berg Balance Scale (BBS) and Morse Falls Scale (MFS) to predict falls in an inpatient stroke rehabilitation setting.

Methods: A longitudinal study involving a secondary analysis of health record data from 818 patients with stroke admitted to an urban, rehabilitation hospital was conducted.

Objective: To evaluate the effectiveness of a 9-month school-based adapted physical activity (APA) program for reducing weight among adolescents with intellectual disability (ID).

Methods: In this randomized controlled trial, adolescents with ID, aged 12-18 years, who were overweight/or with obesity were randomly assigned into intervention and control groups. The APA intervention consisted of aerobic and resistance exercises with an overall moderate intensity and was delivered at a frequency of two sessions per week for 9 months.

Increase in physical activity (PA) might elevate risks for physical-activity-related injuries (PARIs). This study aimed to investigate the incidence rate and risk factors for PARIs among secondary school students in Hong Kong. All eligible students from three secondary schools were invited to participate in the study from November to December 2014.

Objectives: This study aimed to investigate the epidemiological characteristics and preliminarily explore possible risk factors of physical activity-related injury (PARI) occurrences among Chinese university students via a multicentre mixed survey.

Design: Cross-sectional study.

Participants: A total of 4758 undergraduates graded 1-3 in nine universities in three Chinese cities were enrolled via cluster random sampling and completed the self-administered online questionnaires during March and April 2017.

Background: The epidemic of childhood obesity has been well documented in typically developing child populations, while situations among children with intellectual disabilities (ID) remain unclear.

Methods: A cross-sectional study was conducted among 524 Chinese children with ID (males: 68.9%, mean age: 12.

Background: As interventions have expanded beyond clinical treatment to include brief interventions for persons with less severe alcohol problems, predicting who can achieve stable moderation drinking has gained importance. Recent behavioral economic (BE) research on natural recovery has shown that active problem drinkers who allocate their monetary expenditures on alcohol and saving for the future over longer time horizons tend to have better subsequent recovery outcomes, including maintenance of stable moderation drinking. This study compared the predictive utility of this money-based "Alcohol-Savings Discretionary Expenditure" (ASDE) index with multiple BE analogue measures of behavioral impulsivity and self-control, which have seldom been investigated together, to predict outcomes of natural recovery attempts.

Background And Aims: Research using different behavioral economic (BE) and time perspective (TP) measures suggests that substance misusers show greater sensitivity to shorter-term contingencies than normal controls, but multiple measures have seldom been investigated together. This study evaluated the extent to which multiple BE and TP measures were associated with drinking problem severity, distinguished initial outcomes of natural recovery attempts and shared common variance. Hypotheses were (1) that greater problem severity would be associated with greater impulsivity and demand for alcohol and shorter TPs; and (2) that low-risk drinking would be associated with greater sensitivity to longer-term contingencies compared with abstinence.
