A little more conversation, a little more action, please: the carbon footprint of travelling to conferences of the European Health Psychology Society.

Introduction: The environmental impact of on-site conferences, with air travel as the primary contributor to greenhouse gas emissions, has prompted a surge in research in recent years. The objective of this report is to raise awareness and stimulate transformation in the organisation of meetings of the European Health Psychology Society (EHPS).

Methods: We conducted estimations of travel-related COeq emissions of EHPS conferences in 2019, 2022, and 2023, and performed projections for 2024 and 2025.

Extending Our Understanding of the Social Determinants of Physical Activity and Sedentary Behaviors in Families: A Systems Mapping Approach.

Background: The social environment is important to consider for effective promotion of movement behaviors like increased physical activity (PA) and reduced sedentary behavior (SB); yet, it is less often considered than individual and built environments. One way to advance social environment research is to develop system maps, an innovative, participatory, action-oriented research process that actively engages stakeholders to visualize system structures and explore how systems "work." The purpose of this research was to develop PA and SB system maps of the social environment embedded within the core/nuclear family system.

Layperson-Delivered Telephone-Based Behavioral Activation Among Low-Income Older Adults During the COVID-19 Pandemic: The HEAL-HOA Randomized Clinical Trial.

Importance: Older adults are particularly vulnerable to loneliness and its physical and psychosocial sequelae, but scalable interventions are lacking, especially during disasters such as pandemics.

Objective: To compare the effects of layperson-delivered, telephone-based behavioral activation and mindfulness interventions vs telephone-based befriending on loneliness among at-risk older adults.

Design, Setting, And Participants: This assessor-blinded, 3-arm randomized clinical trial screened Chinese older adults through household visits and community referrals from April 1, 2021, to April 30, 2023, in Hong Kong.

Falls prevention is more than just promoting physical health: evaluation of the group-based, out-patient prevention program 'Staying safe and active in old age - falls prevention'.

Introduction: The aim of this study was to evaluate the German falls prevention program 'Staying safe and active in old age - falls prevention', which is already established in practice.

Methods: The single-arm intervention study consisted of two time points, 6 months apart, to evaluate the multifactorial falls prevention program ( = 125 at Time 2). We observed the groups and their trainers and assessed which behavior change techniques (BCTs) were used.

'Who tells me when to stay active or to leave?' age differences in and predictors of endorsement of prescriptive views of aging.

Objectives: Prescriptive views of aging (PVoA) are normative age-based expectations about age-appropriate behavior for older adults, e.g. that they should stay fit/active (active aging norms) but also behave altruistically toward younger generations (altruistic disengagement norms).

Study protocol of the 'HEAL-HOA' dual randomized controlled trial: Testing the effects of volunteering on loneliness, social, and mental health in older adults.

Background: Interventions to reduce loneliness in older adults usually do not show sustained effects. One potential way to combat loneliness is to offer meaningful social activities. Volunteering has been suggested as one such activity - however, its effects on loneliness remain to be tested in randomized controlled trials (RCT).

Effects of volunteering over six months on loneliness, social and mental health outcomes among older adults: The HEAL-HOA Dual Randomized Controlled Trial.

Objective: To determine the beneficial effects of volunteering as lay counselor via telephone on own loneliness, social network engagement, perceived social support, stress, anxiety, and depressive symptoms among Chinese older adults in Hong Kong during the COVID-19 pandemic. DESIGN, SETTING, INTERVENTION, AND PARTICIPANTS: "Helping Alleviate Loneliness in Hong Kong Older Adults" (HEAL-HOA), a dual randomized controlled trial, was implemented to test effects of telephone-based psychosocial interventions delivered by older-adult volunteers for low-income lonely older adults. To evaluate the effects of volunteering on loneliness, we randomized 375 individuals ages 50-70 into a volunteering condition versus an active control (psychoeducation with social gatherings).

Fear of Falling Carries Over into Overprotection in Old Age: A Cross-Lagged Panel Analysis.

Fear of falling might result in overprotection by one's social environment. In turn, feeling dependent could increase fear of falling. However, the association between fear of falling and perceived overprotection and its temporal order is unknown.

Associations Between Implicit and Explicit Condom Use Measures With Condom Use Barriers: Relationships Make A Difference.

Objective: The association between explicit and implicit psychological measures might be affected by the similarity of the assessment method and by the overlap of the components of the constructs being assessed. This study examined the association between condom use barriers and explicit and implicit measurements of condom use and the moderating role of sexual intercourse in these associations.

Design: This was a cross sectional correlational study.

Understanding and overcoming challenges in times of personal or global crisis-Editorial on the Special Issue on Loneliness and Health.

The ever-present interest in loneliness has increased during the last decade. Although loneliness is generally not as prevalent as other topics and not among the top 5 most read papers in the journal Applied Psychology: Health and Well-Being, it is closely connected to topics therein, such as well-being and health. Conceptualizing loneliness as indicator of risk, it may function as a cue for action.

What do older adults think about when formulating implementation intentions for physical activity? Evidence from a qualitative study.

Objectives: Physical activity is an important health behaviour especially for older adults. Forming implementation intentions is an effective strategy to implement physical activity in daily life for young and middle-aged adults. However, evidence for older adults is inconclusive.

What makes implementation intentions (in)effective for physical activity among older adults?

Objectives: For most populations, implementation intentions (IIs) facilitate physical activity (PA). However, for older adults, previous studies found mixed evidence for the effectiveness of this behaviour change technique. To examine which characteristics of IIs predict successful enactment, the content of older participants' IIs formed within a self-regulatory intervention to prompt PA was analysed.

Perceived Physical Functioning and Gait Speed as Mediators in the Association Between Fear of Falling and Quality of Life in Old Age.

Preserving Quality of Life (QoL) in old age gains in importance, but Fear of Falling (FoF) considerably limits QoL. The aim of our study was to understand how physical mediators may translate FoF to QoL. At Time 1, FoF, subjective leg strength, balance, QoL, and objective gait speed were assessed.

Social support, adherence to Mediterranean diet and physical activity in adults: results from a community-based cross-sectional study.

There is a growing recognition that social support can potentially exert consistent or opposing effects in influencing health behaviours. The present paper presents a cross-sectional study, including 2,064 adults from Italy, Spain and Greece, who were participants in a multi-centre randomised controlled trial (C4H study), aiming to examine whether social support is correlated with adherence to a healthy Mediterranean diet and physical activity. Social support data were available for 1,572 participants.

Promoting scientific integrity through open science in health psychology: results of the Synergy Expert Meeting of the European health psychology society.

The article describes a position statement and recommendations for actions that need to be taken to develop best practices for promoting scientific integrity through open science in health psychology endorsed at a Synergy Expert Group Meeting. Sixteen Synergy Meeting participants developed a set of recommendations for researchers, gatekeepers, and research end-users. The group process followed a nominal group technique and voting system to elicit and decide on the most relevant and topical issues.

The effects of psychological inoculation on condom use tendencies and barriers; a randomized controlled trial.

Objective: Condom use prevents the contraction of the HIV. Research shows limited effects of education on increasing condom use. Psychological inoculation (PI) has been found to be more effective in this domain, however, its mechanism is unknown.

Benefits of volunteering on psychological well-being in older adulthood: evidence from a randomized controlled trial.

Long-term volunteering has been associated with better physical, mental, and cognitive health in correlational studies. Few studies, however, have examined the longitudinal benefits of volunteering with randomized experimental designs (e.g.

Self-Efficacy for Physical Activity-A Question of Item Framing and Age?

Older adults process and remember positive information relatively better than negative information, compared with younger adults; this is known as the positivity effect. This study examined whether older adults compared with younger adults also respond differently to positively and negatively framed questionnaire items. Participants (N = 275; age = 18-81 years) were randomly assigned to a positively or negatively framed version of a self-efficacy for physical activity questionnaire.

Promoting Volunteering Among Older Adults in Hong Kong: A Randomized Controlled Trial.

Background And Objectives: Volunteering has consistently been associated with better mental, physical, and cognitive health in older adulthood. However, the volunteering rate of older adults in Hong Kong is much lower than in Western countries. Few studies have examined whether interventions can be effective in motivating older adults to volunteer in Hong Kong.

Study protocol of a multi-center RCT testing a social-cognitive intervention to promote volunteering in older adults against an active control.

Background: Volunteering could be a win-win opportunity for older adults: Links between volunteering and societal improvements as well as older adults' own health and longevity are found in several observational studies. RCTs to increase volunteering in older adults are however sparse, leaving the question of causality unanswered. This study protocol describes a theory-based social-cognitive intervention with multiple behavior change techniques to increase volunteering among community-dwelling older adults in Hong Kong.

Day-to-day mastery and self-efficacy changes during a smoking quit attempt: Two studies.

Objective: In social-cognitive theory, it is hypothesized that mastery experiences (successfully implementing behaviour change) are a source of self-efficacy, and self-efficacy increases the opportunity for experiencing mastery. Vicarious experiences (seeing others succeed) are suggested as another source of self-efficacy. However, the hypothesis of this reciprocal relationship has not been tested using a day-to-day design.

Dietary planning, self-efficacy, and outcome expectancies play a role in an online intervention on fruit and vegetable consumption.

Objective: An online intervention to improve fruit and vegetable (FV) intake examines the role of planning, outcome expectancies, self-efficacy and gender. Women are not only expected to eat more FV than men, but they are also expected to be more responsive to nutritional advice and benefit more from treatment.

Method: A two-arm digital intervention with 269 men and 395 women (M = 41.

Perceived somatic and affective barriers for self-efficacy and physical activity.

According to Bandura's social-cognitive theory, perceptions of somatic and affective barriers are sources of self-efficacy. This longitudinal study compares general indicators of health barriers with measures of perceived somatic and affective barriers to predict self-efficacy and accelerometer-assessed physical activity in a subsample of  = 153 (selected at random from  = 310) community-dwelling German older adults. Perceived somatic and affective barriers longitudinally predicted physical activity mediated by self-efficacy, whereas general health barriers did not.

Who benefits from a dietary online intervention? Evidence from Italy, Spain and Greece.

Objective: The traditional Mediterranean diet includes high consumption of fruits, vegetables, olive oil, legumes, cereals and nuts, moderate to high intake of fish and dairy products, and low consumption of meat products. Intervention effects to improve adoption of this diet may vary in terms of individuals' motivational or volitional prerequisites. In the context of a three-country research collaboration, intervention effects on these psychological constructs for increasing adoption of the Mediterranean diet were examined.

The Role of Self-Efficacy and Friend Support on Adolescent Vigorous Physical Activity.

Objectives: Physical activity, including some form of vigorous activity, is a key component of a healthy lifestyle in young people. Self-efficacy and social support have been identified as key determinants of physical activity; however, the mechanism that reflects the interplay of these two factors is not well understood. The aim of the current study was to test social cognitive theory's notion that self-efficacy relates to intention that translates into behavior and to investigate whether friend support and self-efficacy synergize, interfere, or compensate for one another to predict vigorous physical activity in adolescents-a population at risk of rapid decreases in physical activity.
