Time for change: using implementation intentions to promote physical activity in a randomised pilot trial

Objective: A common barrier to exercise is a perceived lack of time. The current pilot study examined the effects of an implementation intention intervention to enhance exercise self-efficacy, increase confidence to exercise when facing time constraints, and increase physical activity in middle-aged adults (n?=?63, aged 35–69). Design: Participants received a pedometer (Fitbit) to objectively measure activity and were randomly assigned to either a control or intervention condition. After a 1-week baseline, the intervention condition received instructions to plan how, where, and when they would add steps to their daily routine to meet their step goal, using personalised schedules and maps. Both groups were contacted nightly via email. Main Outcome Measures: Physical activity (steps and time spent in moderate-to-vigorous activity), goal achievement, exercise self-efficacy, time-relevant exercise self-efficacy and affect. Results: Compared to the control, the intervention condition significantly increased in steps, time spent in moderate-to-vigorous activity, and time-relevant exercise self-efficacy. Goal achievement was related to greater time-relevant exercise self-efficacy and more positive affect at the daily level. Conclusion: Findings suggest that the personalised planning intervention increased physical activity and confidence in achieving physical activity goals under time constraints. Avenues for future directions, especially for producing more sustained effects, are discussed.     

Efficacy of a Brief,School‐Based Bystander Bullying Intervention on High School Students' Alcohol Use

The authors examined the efficacy of a brief bystander bullying intervention on reducing alcohol use among high school students (N = 61). As hypothesized, high‐risk drinkers in the intervention group reported reduced drinking compared with control students at a 30‐day follow‐up.     

Encouraging children to mentalise about a perceived outgroup increases prosocial behaviour towards outgroup members

We investigated whether encouraging young children to discuss the mental states of an immigrant group would elicit more prosocial behaviour towards them and impact on their perception of a group member's emotional experience. Five‐ and 6‐year‐old children were either prompted to talk about the thoughts and feelings of this social group or to talk about their actions. Across two studies, we found that this manipulation increased the extent to which children shared with a novel member of the immigrant group who was the victim of a minor transgression. The manipulation did not lead to greater sharing towards a victim from the children's own culture and did not influence their perception of a victim's negative emotions. These results may ultimately have implications for interventions aimed at fostering positive intergroup relations within the context of immigration.     

Early executive functioning in a global context: Developmental continuity and family protective factors

This study extends the methodological and theoretical understanding of executive functions (EFs) in preschoolers from low‐ and middle‐income countries (LMIC). First, the authors describe a rigorous process of adapting and evaluating six EF tasks to produce a culturally and developmentally appropriate measure of emerging EFs in a large sample of at‐risk children in rural Pakistan. Next, the authors identify critical developmental and family factors that relate to preschoolers’ EFs over the first 4 years of life. Direct assessment of children's general cognitive skills at age two showed developmental continuity with EFs at age four, and these early cognitive skills mediated the effect of an antecedent parenting intervention on EFs as well as associations of targeted individual and family factors with EFs. Furthermore, directly assessed maternal cognitive capacities and observed maternal scaffolding uniquely predicted EFs in preschoolers. This study is also the first to demonstrate a significant overlap between direct assessments of IQ and EFs in young children from LMIC. Children's general intelligence mediated the associations of EFs with antecedent physical growth and cognitive skills as well as concurrent family factors (maternal verbal intelligence, maternal scaffolding, and home stimulation). After controlling for shared variance between preschoolers’ general intelligence and EFs, three factors emerged as unique predictors of EFs: exposure to an early parenting intervention, physical growth status at age two, and number of older siblings. The findings have important implications for the design of interventions that aim to improve EFs in young children in LMIC.

“This phone saved my life”: Older persons’ experiences and appraisals of an mHealth intervention aimed at addressing loneliness

This qualitative study aimed to explore older persons’ experiences and appraisals of the utility of an mHealth intervention for reducing their sense of loneliness. Participants (n = 13; 86.42% females; age range 65 to 87 years) received training in the use of a smartphone and a social networking application (WhatsApp). Following the intervention, they completed a focus group discussion. For data triangulation, participants shared their social media postings. Content analysis of the focus group discussion and social media data indicated that the mobile device was used to mitigate perceptions of loneliness and isolation, thus facilitating social network building, enhancing self-efficacy, and improving cognitive flexibility. Mobile phones and a social networking application appear to reduce loneliness experienced by the elderly.

条件性恐惧记忆消退的提取干预范式及其作用的神经机制

基于记忆再巩固理论的恐惧记忆提取干预范式被证明可以有效消退恐惧记忆, 能克服传统消退容易复发的缺点。该范式通过单独呈现条件刺激激活原有恐惧记忆, 使记忆重返不稳定状态, 随后在再巩固时间窗内实施干预则能改写原有记忆。目前该范式起作用的神经机制尚不明确, 本文在现有的人类研究和动物研究基础上, 总结了杏仁核、前额叶和海马三个脑区在提取干预过程中的作用, 以及该领域研究的争议点, 为之后的研究提供思路。     

Presenting concerns of emerging adults seeking treatment at an early intervention outpatient mood and anxiety program

This study examined presenting concerns and characteristics of emerging adults (EAs) seeking treatment at an early intervention program for mood and anxiety disorders to better understand presenting concerns when treatment is needed. During an intake assessment conducted by a social worker or clinical psychologist, participants (N = 548; 62% female, 38% male) reported their top three current life concerns, which were analyzed qualitatively using thematic analysis. Participants completed a battery of questionnaires assessing demographic information, symptomatology, and daily functioning. Females presented with significantly higher levels of anxiety, and both females and younger individuals (age 16–18) presented with significantly higher levels of depression compared to males and older individuals (age 19–26), respectively. The two most commonly reported presenting concerns were problems in interpersonal relationships and academics, and females were more likely to report academic concerns than males. The majority of participants reported seeking help for a wide range of problems commonly faced by EAs (83.7%), and participants rarely expressed concerns about particular symptoms of mood and/or anxiety disorders (16.3%). EAs and those supporting EAs may benefit from learning when psychosocial concerns are indicative of mental health challenges warranting professional attention.     

Does job crafting assist dealing with organizational changes due to austerity measures? Two studies among Greek employees

In this paper, we focussed on Greek employees that are heavily affected by austerity-led organizational changes, and studied whether job crafting (defined as seeking resources, seeking challenges, reducing demands) helps them deal with these changes. In the first, cross-sectional study we examined whether job crafting relates to adaptive performance, and whether individuals’ assessment of changes moderates this relationship. The results showed that the relationship between reducing demands and adaptive performance was positive for those assessing the changes more positively, and negative for those assessing them more negatively. This interaction was replicated in the second, quasi-experimental field study, where we examined the effects of an intervention designed to help employees deal with organizational changes and increase their well-being, adaptive performance and openness to such changes by stimulating job crafting behaviours. Participants received training and worked for 3 weeks on self-set job crafting goals. The intervention was effective in increasing reducing demands, positive affect and openness to change. Moreover, it had a positive effect on openness to change and adaptive performance through positive effect, but a negative effect on adaptive performance through reducing demands. Thus, the intervention facilitated to some extent employee functioning under unfavourable working conditions that result from austerity measures.
