How young adults view older people: Exploring the pathways of constructing a group image after participation in an intergenerational programme

In recent years, a multitude of intergenerational contact programmes and interventions has emerged to counteract ageism among young adults. Research on these programmes and its supposed effect on ageism often start from the assumption that intergenerational contact follows a largely linear process in which a high level of encounters, in the right setting, decreases ageism and negative stereotyping. The purpose of this article is to critically examine this assumption by focussing on the underlying process of intergenerational contact, rather than examining the positive or negative outcome. Using in-depth interviews with 35 young adults, we found that although conditions and mediating factors during the contact do play a role in the outcome of intergroup contact, the process of contact is rather varied and does not follow a linear path. The results reveal that whether or not a positive contact experience translates into a changed group image of older people is related to the positioning of such experience within the young adults' personal frame of reference. We found that this has to do with the young adults having diverse and both positive and negative previous experiences, their grandparent-grandchild relationship, stories from others and personal characteristics. With this study, we point to the complexity of intergenerational contact and highlight potential pathways leading to varying group images of ‘the old’.

Suicide reattempt in a population-wide brief contact intervention to prevent suicide attempts: The VigilanS program, France.

Among the postcrisis suicide prevention programmes, brief contact interventions (BCIs) have been proven to be efficient. VigilanS generalizes to a whole French region a BCI combining resource cards, telephone calls, and sending postcards, according to a predefined algorithm. However, a major problem in suicide prevention is the suicide reattempt, which can lead to final suicide. Here, we analyze the suicide reattempt in VigilanS. The study concerned patients included in VigilanS over the period from January 1, 2015 to December 31, 2018, with an end of follow-up on July 1, 2019. We performed a series of descriptive analyses, survival curves, and regressions. The outcome was the suicide reattempt, and the predictive variables were the characteristics of the patient at entry and during follow-up in VigilanS. Age and sex were considered as adjustment variables. A total of 11,879 inclusions occurred during the study period, corresponding to 10,666 different patients, among which 905 reattempted suicide. More than half were primary suicide attempters (53.4%). A significant relationship with suicide reattempt was identified for the following characteristics: being a non-primary suicide attempter, having attempted suicide by voluntary drug intoxication and phlebotomy, alcohol consumption among primary suicide attempters, and having no companion at the emergency room visit among non-primary suicide attempters. Hanging (as suicide method), having made no call to VigilanS were protective factors. This study provides us with a valuable insight into the profiles of patients repeating a suicide attempts, which is important for suicide prevention in general.

Novel behavioural approaches and implementation science for mitigating genetic risk of cardiovascular disease due to elevated lipoprotein(a)

Elevated lipoprotein(a) [Lp(a)] is a genetic trait that indicates higher risk of atherosclerotic cardiovascular disease (ASCVD). We review novel strategies to mitigate behavioural risk-factors in this genetic condition. Pharmacological and biological interventions are available for lowering Lp(a). However, the acceptability and feasibility of these approaches are questionable due to cost and lack of clinical evidence for their efficacy. A number of low-cost, minimal patient contact interventions are available for modifying behavioural risk-factors that are associated with increased risk of ASCVD familial hypercholesterolaemia and diabetes. These include lifestyle interventions designed to improve diet and physical activity. These interventions may be particularly important among individuals with elevated Lp(a) to manage their higher risk of diabetes and ASCVD. The following article outlines recent research that has examined such low-cost, minimal patient contact interventions. The current research indicated that such interventions, which are grounded in psychological theory, can assist individuals to improve their diet and physical activity. These findings have implications for developing and implementing similar interventions for individuals with elevated Lp(a), so as to assist in reducing behavioural risk-factors associated with ASCVD.

Cost-effectiveness of a Contact Intervention and a Psychotherapeutic Program for Post-discharge Suicide Prevention.

To determine the cost-effectiveness of 2 strategies for post-discharge suicide prevention, an Enhanced Contact intervention based on repeated in-person and telephone contacts, and an individual 2-month long problem-solving Psychotherapy program, in comparison to facilitated access to outpatient care following a suicide attempt. We conducted a cost-effectiveness analysis based on a decision tree between January and December 2019. Comparative effectiveness estimates were obtained from an observational study conducted between 2013 and 2017 in Madrid, Spain. Electronic health care records documented resource use (including extra-hospital emergency care, mortality, inpatient admission, and disability leave). Direct cost data were derived from Madrid's official list of public health care prices. Indirect cost data were derived from Spain's National Institute of Statistics. Both augmentation strategies were more cost-effective than a single priority outpatient appointment considering reasonable thresholds of willingness to pay. Under the base-case scenario, Enhanced Contact and Psychotherapy incurred, respectively, €2,340 and 6,260 per averted attempt, compared to a single priority appointment. Deterministic and probabilistic sensitivity analyses showed both augmentation strategies to remain cost-effective under several scenarios. Enhanced Contact was slightly cost minimizing in comparison to Psychotherapy (base-case scenario: €-196 per averted attempt). Two post-discharge suicide prevention strategies based on Enhanced Contact and Psychotherapy were cost-effective in comparison to a single priority appointment. Increasing contacts between suicide attempters and mental health-care providers was slightly cost minimizing compared to psychotherapy.

Reducing prejudice toward Syrian refugee children: A vicarious contact intervention among Turkish elementary school children.

We conducted an experimental intervention to test the effectiveness of vicarious contact in the relationship between Turkish and Syrian elementary school children; the participants were Turkish children. We used a mixed-methods approach, investigating effects by using both quantitative and qualitative methodologies. Participants in the experimental condition were asked to read stories on positive contact between Turkish and Syrian children over the course of six weekly sessions. The results revealed that vicarious contact, compared to a control condition where participants did not engage in any activity, led to greater intentions to help outgroup members. Importantly, effects only emerged among children who reported higher initial negative outgroup attitudes. Results from qualitative data revealed that vicarious contact produced richer, more positive, and complex representations of the relationships and friendships between groups. We discuss the theoretical and practical implications of these findings.

Efficacy of contact intervention videos on college students’ intentions toward mental health help-seeking

Objective Untreated mental health (MH) concerns have significant implications for college students. This study examined the efficacy of a video contact intervention targeting students’ intentions to seek counseling. Participants: One-hundred and sixty-three college students (M age = 21.05, SD = 2.20) from a Mid-Atlantic university participated. The sample was predominantly female (74%). Method: Students were randomly assigned to view a student-targeted contact video (ie, clips from college students who share their mental health experiences), a MH comparison contact video, or a non-MH comparison video. Intentions to seek counseling and psychological distress were measured pretest and post-test. Results: Intentions to seek counseling significantly increased from pretest to post-test in the student-targeted contact video condition (F[1, 156] = 22.75, p < .001, partial η 2 = .13), but not in the comparison conditions. Further, this effect was only observed among participants who reported preexisting psychological distress (F[1, 153] = 28.00, p < .001, partial η 2 = .16). Conclusions: This study provides initial support for the utility of a student-targeted contact intervention video for increasing help-seeking intentions among those reporting current psychological distress.

School Mental Health Curriculum Effects on Peer Violence Victimization and Perpetration: A Cluster-Randomized Trial.

Addressing school violence is an important public health goal. To assess the role of school mental health curricula in violence prevention, we evaluated effects of an anti-stigma curriculum on violence victimization/perpetration. An ethnically/socioeconomically diverse sample of 751 sixth-graders (mean age 11.5 years) across 14 schools in Texas were block-randomized by school (2011-2012) to receive singly or in combination: (1) a mental illness anti-stigma curriculum; (2) contact with 2 young adults with mental illness; or (3) merged control (printed materials/no intervention). Pre- and post-test assessments were self-completed during health education classes; prior to randomization, 484 (64.5%) agreed to 2-year, home-based longitudinal assessments. Statistical models tested short- and long-term effects on physical, verbal, and relational/social violence victimization/perpetration. At 1-month post-test, students who received the curriculum versus control made fewer verbal threats (p < .05). Those with high-level mental health symptoms in the curriculum group versus control used less violence overall and received fewer verbal threats from peers short-term (p < .05). Curriculum effects of reducing violence perpetration sustained long-term among adolescents with high-symptoms (p < .01). The comparator contact intervention was ineffective short- and long-term. Implementing efficacious mental health curricula can serve as a multi-pronged strategy with anti-bulling efforts to prevent violence and improve mental health.

Acceptability of personal contact interventions to address loneliness for people with dementia: An exploratory mixed methods study.

Personal contact interventions involve routine visits with a person or animal to address loneliness. Research supports the promise of these interventions to address loneliness among cognitively intact older adults, but little is known about their use with people with dementia. To assess the acceptability of personal contact interventions for use to address loneliness with older people with dementia, according to formal and informal care providers. Cross-sectional, mixed methods complementarity design. Ontario, Canada. A purposive sample of 25 family members, friends, and health care providers of people with dementia. Participants attended a face-to-face interview to discuss the acceptability of personal contact interventions. Participants completed questionnaires to rate acceptability (adapted Treatment Perception and Preference measure). A semi-structured interview followed to discuss the ratings and features of personal contact (with another person or animal) in more detail. The analysis involved descriptive statistics (quantitative data) and conventional content analysis (qualitative data). During the interpretation of the results, the qualitative findings were compared to the quantitative results to provide context and understand participants' perceptions of intervention acceptability in more depth; these are presented together in the results to demonstrate their distinct and complementary contributions to the findings. Personal contact with a person or animal was rated as effective, logical, suitable, and low risk to address loneliness by over 80% of participants. Participants' willingness to engage in this type of contact, for example as a visitor or as a facilitator of animal contact, was 72%. Participants emphasized the benefits of personal contact. The findings highlight that individualized, flexible interventions that include appropriate facilitation are needed. Future studies to develop and test personal contact interventions should involve flexible delivery, assess the feasibility and acceptability of these interventions (as in a Phase 2 trial of a complex intervention), and focus on the experiences of people with dementia.Tweetable Abstract: Tailored, routine, and facilitated contact with a person or animal shows promise to address loneliness for people with dementia.What is already known about this topic:• Loneliness is emotionally painful and harms the health and quality of life of those that experience it.• Personal contact interventions refer to routine visits with another person or animal and have been found effective in addressing loneliness among cognitively intact older adults.What this paper adds:• Friends, family members and health care providers of people with dementia view personal contact interventions as logical, suitable and effective to address loneliness of older adults with dementia.• Personal contact interventions are not always easy to implement and do not automatically promote meaningful connection and prevent loneliness for people with dementia.• Strategies to tailor and facilitate personal contact interventions are needed to promote their effectiveness when used with people with dementia.

Walking in My Shoes: Imagined Synchrony Improves Attitudes Towards Out-groups

People are prone to dividing others into the categories of ‘us’ and ‘them’. This can be particularly detrimental to minorities who may experience social exclusion, prejudice, and reduced access to equal opportunities. One method of improving intergroup relations is to create opportunities for contact. Common contact interventions have members of different groups meet and engage in conversation. There are also non-verbal embodied intergroup activities that produce the same effects. Previous work has shown that the pro-social effects of coordination may be linked to whether co-actors are classed as in or out-group members. The current study explored whether imagining walking in synchrony with in- or out-group members changed majority members’ attitudes towards those individuals. Imagining walking in synchrony fostered greater increases in empathy and decreases in negative attitudes only towards minority group members following imagined coordination (not in-groups). Implications and future directions are discussed.

Developing and testing a discrete event simulation model to evaluate budget impacts of diabetes prevention programs.

Type 2 diabetes (T2D) is one of the most rapidly increasing non-communicable diseases worldwide. Lifestyle interventions are effective in preventing T2D but also resource intensive. This study evaluated with discrete event simulation (DES) the relative budget impacts of three hypothetical diabetes prevention programs (DPP), including group-based contact intervention, digital program with human coaching and fully automated program. The data for simulation were derived from research literature and national health and population statistics. The model was constructed using the iGrafx Process for Six Sigma software and simulations were carried out for 10years. All simulated interventions produced cost savings compared to the situation without any intervention. However, this was a modeling study and future studies are needed to verify the results in real-life. Decision makers could benefit the predictive models regarding the long-term effects of diabetes prevention interventions, but more data is needed in particular on the usage, acceptability, effectiveness and costs of digital intervention tools.

Assessing the Efficacy of a Self-Administered Treatment for Social Anxiety in the Form of a Gamified Mobile Application: A Pilot Study

Social anxiety disorder (SAD) is a highly prevalent and impairing mental disorder that often goes untreated. Because effective treatments exist but are not reaching many with SAD, it is important to investigate and design novel treatment delivery methods. To this end, our study set out to determine whether such a treatment could be effectively delivered through a new phone application featuring two novel mechanisms: (1) delivery of the treatment on a mobile smartphone and (2) the gamification of the treatment. Utilizing a single-subject multiple baseline across participants design, the efficacy of the treatment was evaluated on a sample of undergraduate students (N = 10) who endorsed significant levels of social anxiety on a self-report measure. Participants completed assessments every 4 days during a 12-, 16-, or 20-day baseline phase and a 44-, 40-, or 36-day treatment phase. At the study’s conclusion, participants showed a statistically significant mean decrease in scores on both the Brief Fear of Negative Evaluation Scale and the Liebowitz Social Anxiety Scale. In addition, the results evidenced high rates of completion, lending support for the acceptability of the treatment modality. Future research comparing purely self-guided interventions with minimal therapist contact interventions and traditional face-to-face treatment are needed, with further investigations into gamification as a potential mechanism for increasing adherence and motivation.

Cluster randomized controlled trial (RCT) to support parental contact for children in out-of-home care

BackgroundThere is an identified need to improve the evidence-base in relation to contact visits for children in the out-of-home-care (OOHC) system, to ensure optimal outcomes. ObjectiveThe aim of this cluster randomized controlled trial (RCT) was to test the effectiveness of a contact intervention for parents having supervised contact with children in long-term OOHC. Participants183 study children in 15 clusters (OOHC services) and their parent(s) were randomized to the intervention (8 clusters, 100 children) and control groups (7 clusters, 83 children) in three Australian jurisdictions. SettingThe manualized intervention consisted of increasing the preparation and support provided by caseworkers to parents before and after their contact visits. MethodInterviews were conducted with carers, parents and caseworkers of the study children at baseline and nine months post-randomization. Interviews included standardized assessment tools measuring child and adult wellbeing and relationships, carer and caseworker ability to support contact, and contact visit cancellations by the parent. ResultsCompared with controls, the intention-to-treat (ITT) analyses showed that fewer visits were cancelled by parents in the intervention group at follow-up (−10.27; 95 % CI: −17.04 to −3.50, p = .006). In addition, per-protocol (PP) analyses showed higher caseworker receptivity to contact (6.03; 95 % CI: 0.04–12.03, p = .04), and higher parent satisfaction with contact (7.41; 95 % CI: 0.70–14.11, p = .03) in the intervention group at follow-up. ConclusionsWhile the intervention did not have an effect on child wellbeing, as measured by the SDQ, the trial reports significant positive findings and demonstrates the benefits of the kC kContact intervention in providing support to parents to attend contact visits. The findings of the current study provide an important contribution to knowledge in an area where few RCTs have been completed, notwithstanding the null findings.

A Randomized Controlled Trial to Assess Feasibility and Acceptability of Telephone-Based Psychosocial Interventions in Individuals who Attempted Suicide.

Background:Brief contact interventions such as telephone-based contacts appear to be useful in individuals who attempted suicide. Most studies of telephone-based contacts in such individuals typically consisted of frequent phone reminders for adherence to treatment and seeking help for mental health issues. Telephone-based psychosocial interventions that incorporate elements of supportive and problem-solving strategies are of interest in Indian settings due to their potential application in mitigating the wide mental health gap. Feasibility studies of telephone-based psychosocial interventions could help ascertain the difficulties that arise in the implementation of such treatments.Methods:A multicentric randomized controlled trial (RCT) is currently underway in general hospital settings in two Indian cities to study the efficacy of telephone-based psychosocial interventions in individuals with a recent suicide attempt, with routine telephone contacts (TCs) serving as the comparator. Prior to that RCT, this feasibility study was conducted to assess the acceptability of the telephone-based intervention and telephone contacts. Feasibility was assessed using dropout rates. Acceptability was assessed using participant-rated Likert-based visual analog scores from 0 to 10, with higher scores indicating greater acceptability.Results:Dropout rates and mean acceptability scores for telephone-based psychosocial interventions were 38.5% and 8.63, while those for TCs were 41.7% and 7.57, respectively.Conclusions:Telephone-based psychosocial interventions are feasible and acceptable in individuals with a recent suicide attempt.

The effectiveness of a contingent financial incentive to improve trial follow up; a randomised study within a trial (SWAT).

Objectives To evaluate the effectiveness of a contingent financial incentive (£10 note in addition to a routinely provided £10 voucher) versus no contingent financial incentive, on improving the retention rate in a randomised controlled trial (RCT). Methods A two arm 'Study within a Trial' (SWAT) embedded within a host RCT (SCIMITAR+). Participants were randomised to the SWAT using a 2:1 (intervention:control) allocation ratio. The primary outcome measure was the proportion of participants completing a CO breath measurement at the first SCIMITAR+ follow up time point (6 months). Secondary outcomes were withdrawing from follow-up after contact and time from assessment due date to completion. Analyses were conducted using logistic or Cox Proportional Hazards regression as appropriate. Results A total of 434 participants were randomised into this SWAT. Completion of the CO breath measurement at 6 months was 88.5% (n=247) in the intervention arm of the SWAT and 85.4% (n=123) in the control arm (Difference 3.1%, OR 1.29, 95% CI 0.71-2.33, p=0.41). There was also no evidence of a difference in the proportion of participants withdrawing from follow-up after contact (intervention n=7 (2.5%), control n=5 (3.5%); OR 0.76, 95% CI 0.23-2.44, p=0.64), nor in terms of proximity of 6-month visit completion to due date (HR 1.07, 95% CI 0.86-1.33, p=0.55). Conclusion It is unclear if contingent financial incentives increased rates of face-to-face follow-up completion within the SCIMITAR+ trial population. However, the sample size of this SWAT was constrained by the size of the host trial and power was limited. This SWAT adds to the body of evidence for initiatives to increase response rates in trials.

Unjudge Someone: Human Library as a Tool to Reduce Prejudice toward Stigmatized Group Members

Human Library (HL) is a nonprofit community event aimed at increasing awareness and reduction of prejudice toward stigmatized groups in the society. HL implements an unusual methodology in the format of a pretend ‘library’ where HL attendants so-called ‘Readers’ engage in short, face-to-face, direct contact with so-called ‘Books’ who are real individuals from various stigmatized social groups. Although HL has been widely used in various contexts since 2000’s and is recommended as the best practice of integration by European Commission, empirical research testing its effectiveness is limited. Our study presented the findings from four consecutive HL events conducted from 2016 to 2019 in Turkey (total N = 534). Including various control groups, we tested the effectiveness of HL as a direct intergroup contact intervention on affective (trust, empathy), cognitive (knowledge), and behavioral (e.g., willingness to talk to outgroup members) aspects of outgroup attitudes. Findings demonstrated that while overall outgroup attitudes became more positive after HL attendance, unlike merely participating in the event or not attending HL, actual contact (‘Reading a Book’), in particular, improved attitudes toward the target groups. While supporting the overall benefits of HL methodology as a contact intervention, our study demonstrated that HL may be more effective on certain dimensions of attitudes. Practical implications and possible limitations of HL, as well as perspectives for future research were discussed.

Opening the black box of contact: Unravelling the ways through which positive contact is imagined in a post‐conflict context

AbstractWhile there is growing support for the prejudice‐reduction effects of imagined contact, knowledge of the content of imagery in imagined contact studies remains scarce. This qualitative study aims to address this gap by unravelling the ways of imagining an intergroup encounter that is indeed positive. Our data consist of the imagined contact stories of 43 participants in two imagined contact studies conducted in Cyprus, a post‐conflict context characterised by low levels of contact because of long‐standing division across ethnic lines. Our analysis yielded four themes corresponding to four ways of construing positive contact: imagining a good Other, a similar Other, an inferior Other, as well as imagining successfully overcoming obstacles emerging before or during contact. While participants came up with ways to imagine positive contact that are consistent with intergroup contact literature (e.g., intergroup similarities, decategorisation), a closer look at the findings reveals that in composing a positive intergroup experience, participants made use of dysfunctional stereotypes and conflict‐perpetuating narratives whose objective is to protect their superior status and to ensure their safety during contact. The findings serve as a word of caution for imagined contact as a prejudice‐reduction intervention and they also attest to the importance of deeply knowing the psychological composition of the groups which (imagined) contact interventions typically aim to tackle.

A Winding Road to Peace Building: Longitudinal Outcomes of a Peace Intervention for Survivors and Génocidairesof the 1994 Genocide Against the Tutsi in Rwanda.

This longitudinal study examined outcomes of a local peace-building intervention that applied principles of intergroup contact to promote reconciliation between génocidaires and survivors whom they have directly harmed during the 1994 Genocide Against the Tutsi in Rwanda. Individual interviews were conducted with 46 génocidaires and 45 survivors whom they have directly harmed during the genocide at 7-time points over the course of their 22-month participation in three programmatic activities (workshops, cell groups, and cooperative cow raising). One thousand bootstrapped samples generated to measure changes in outcomes indicated that survivors and génocidaires regarded themselves and those who directly impacted them during the genocide more positively after 22months. Although both survivors and génocidaires experienced significant decline in trauma symptomatology after 22months, they responded to programmatic activities differently. Cell group interactions sustained some positive outcomes (génocidaires perceived forgiveness by others) after the workshops and further improved others (génocidaires self-forgiveness). Survivors who participated in cell groups and raised cows with génocidaires demonstrated further willingness to reconcile compared to survivors who participated in cell groups alone. Our findings empirically support the benefits of promoting different forms of intergroup interactions long after a period of intense violence and highlight the importance of considering how the trajectories of outcomes can inform program and theory development. HIGHLIGHTS: Survivors and génocidaires in Rwanda benefited from a local intergroup contact intervention (CI). However, génocidaires and survivors they directly harmed benefited differently over 22-months. Preparing survivors and génocidaires with skills to participate in communal life is critical for CI. Highlighting both CI outcomes and trajectories are essential for program and theory development.

A single-blind clustered randomised controlled trial of daily record-keeping for reducing smoking tobacco expenditure among adult male household heads in rural Bangladesh

AbstractIntroductionThis study aims to assess the impact of a behavioural intervention, in the form of a self-monitoring record-keeping logbook, in reducing smoking tobacco expenditure amongst adult male household heads in rural Bangladesh.MethodThe experiment was designed as a single-blind clustered randomised controlled trial utilising two-stage random sampling. A total of 650 adult male household heads were sampled from 16 chars (riverine islands) from Gaibandha, Northern Bangladesh, with eight chars in treatment and control groups each, between November 2018 and January 2019. The intervention consisted of a logbook to record daily smoking tobacco intake for 4 weeks provided only to participants in treatment chars (n = 332) while households in control chars received nothing (n = 318).ResultsFinal analysis was conducted using 222 and 210 households in the treatment and control chars respectively. The logbook intervention had a significant impact (P-value = 0.040) on reducing daily tobacco expenditure by 14% (α = 95%; CI: −0.273, −0.008) for the treatment group relative to the control group based on a difference-in-difference estimator. This is equivalent to a reduction of 20 cigarettes or 140 bidis smoked in a month.ConclusionOur minimal contact intervention successfully induced a reduction in smoking tobacco expenditure, which could effectively be incorporated with existing programs in the char regions of Bangladesh.

Moving beyond the past: The role of historical closure in conflict resolution

This article discusses the role of historical closure in conflict resolution and reconciliation, departing from the example of the Polish Round Table negotiations in 1989. The concept of a “thick line” (“Gruba kreska” or “Schlussstrich”) was used in several historical contexts, showing the intention to detach from history when resolving pressing current societal issues. Historical evidence suggests that it was an intentionally chosen strategy by both sides taking part in the Round Table negotiations in 1989. Historical closure is known to have good consequences for building mutual trust, improving attitudes and making contact interventions more effective in improving intergroup relations. This is mostly attributed to the fact that historical crimes can have a long-standing impact on intergroup relations: past victimhood and perpetratorship lead to current grievances, denial, and mistrust. Only when these historical roles are overcome can both parties achieve any agreement. At the same time, historical closure breeds a sense of injustice among political followers and gives birth to numerous conspiracy theories. This article analyzes these problems in the Polish context and beyond.
