Evidence of improved fluid management in patients receiving haemodialysis following a self-affirmation theory-based intervention: A randomised controlled trial

Objective: Haemodialysis patients are at risk of serious health complications; yet, treatment non-adherence remains high. Warnings about health risks associated with non-adherence may trigger defensive reactions. We studied whether an intervention based on self-affirmation theory reduced resistance to health-risk information and improved fluid treatment adherence.

Design: In a cluster randomised controlled trial, 91 patients either self-affirmed or completed a matched control task before reading about the health-risks associated with inadequate fluid control.

Outcome measures: Patients’ perceptions of the health-risk information, intention and self-efficacy to control fluid were assessed immediately after presentation of health-risk information. Interdialytic weight gain (IDWG), excess fluid removed during haemodialysis, is a clinical measure of fluid treatment adherence. IDWG data were collected up to 12 months post-intervention.

Results: Self-affirmed patients had significantly reduced IDWG levels over 12 months. However, contrary to predictions derived from self-affirmation theory, self-affirmed participants and controls did not differ in their evaluation of the health-risk information, intention to control fluid or self-efficacy.

Conclusion: A low-cost, high-reach health intervention based on self-affirmation theory was shown to reduce IDWG over a 12-month period, but the mechanism by which this apparent behaviour change occurred is uncertain. Further work is still required to identify mediators of the observed effects.     

Sex,germs, and health: pathogen-avoidance motives and health-protective behaviour

Objective: Recent work suggests that the psychology of pathogen-avoidance has wide-reaching effects on how people interact with the world. These processes – part of what has been referred to as the behavioural immune system – are, in a way, our ‘evolved’ health psychology. However, scholars have scarcely investigated how the behavioural immune system relates to health-protective behaviours. The current research attempts to fill this gap.

Design: Across two cross-sectional studies (N = 386 and 470, respectively), we examined the relationship between pathogen-avoidance motives and health-protective behaviour.

Outcome Measures: The studies used self-reported measures of attitude and intention as indicators of health-protective behaviour.

Results: Data collected in Study 1 revealed that pathogen-avoidance motivation related to participants’ attitude and intention towards sexually transmitted infections screening. High levels of pathogen-avoidance motivation were also related to having had fewer sexual partners, which partially mediated the effect of pathogen-avoidance variables on testing motivation. Study 2 extended these findings by showing moderate associations between pathogen-avoidance motivation and a broad range of health-protective behaviours, including but not limited to pathogen-related health concerns.

Conclusion: We argue that understanding and targeting pathogen-avoidance psychology can add novel and important understanding of health-protective behaviour.     

两类线索相容性的比较研究

研究运用前置线索的实验模式,采用对颜色刺激进行不一致颜色命名的实验任务,考察了线索与刺激和反应的维度重合关系、线索的呈现时距和线索的有效慨率对命名时间的影响。研究表明：在无刺激一反应相容性的情况下,当线索一刺激和线索一反应这两类线索相容性同时存在却相互竞争时,线索一刺激的相容性强于线索一反应的相容性,只显示出线索一刺激的相容性效应。同时,实验结果证明了线索一刺激相容性效应仍然遵循适时性的特征,受到线索呈现时距的影响,并随线索客观有效慨率的增加而增强。     

From self‐disclosure to prosocial behaviour: Feedback as a moderator

Prosocial behaviours and their correlates have been extensively studied; however, few studies have examined the linkage between self‐disclosure and prosocial behaviours. Three studies were conducted aimed at examining the relationship between self‐disclosure and prosocial tendencies, as well as the moderating role of feedback from the help provider's perspective. We hypothesized that participants' self‐disclosure was positively associated with his/her prosocial tendencies and that this association would be moderated by feedback received. The results generally support our hypotheses, and reveal that participants with higher levels of self‐disclosure tend to exhibit more prosocial tendencies (Studies 1 and 2), but this association was only true for those participants that received self‐disclosure feedback (Study 3). The present study suggests that, other than self‐disclosure, reciprocal feedback also plays an important role in promoting prosocial behaviours.

Dementia and Suffering in Nursing Homes

SUMMARY

This paper uses case studies of challenging behaviour associated with dementia to demonstrate, firstly, that disturbed behaviour is often a manifestation of suffering caused by multiple phenomena such as medical problems or the care environment. Addressing these causes instead of simplistically ‘treating the behaviour’ usually reduces the behaviour. Secondly, staff distress with a particular difficult resident is often caused by more general fundamental problems such as a lack of support or knowledge. Addressing these problems reduces staff distress. Finally, results from a Swedish intervention study are presented. They show that suffering for both staff and residents can be reduced, and quality of life improved, by providing increased autonomy for hands-on staff, systematic emotional support, and collaboratively developing care plans based on each resident's emotional and physical needs, rather than the problems they present.

Maternal Behavior and Children's Early Emotion Regulation Skills Differentially Predict Development of Children's Reactive Control and Later Effortful Control

The role of maternal behavior and children's early emotion regulation skills in the development of children's reactive control, specifically behavioral impulsivity, and later effortful control was examined in a sample of 435 children. HLM analyses indicated significant growth in reactive control across the toddlerhood to early childhood period. Emotion regulation at age-2 positively predicted initial levels of children's reactive control abilities while maternal overcontrol/intrusiveness predicted lower levels of reactive control growth. Maternal behaviors at age-2 predicted children's effortful control abilities at age-5.5. Emotion regulation did not predict effortful control abilities. Maternal behavior and children's early emotion regulation skills may differentially facilitate the development of reactive and effortful control abilities.     

Antecedents of risk-taking behaviour among South African adolescents

This study aimed to investigate contextual predisposition to risk-taking behaviour among South African adolescents. Participants included 194 black adolescents from central South Africa (female = 50.5% between the ages of 16 and 19 years). The adolescents completed a youth risk behaviour survey as well as a questionnaire on their parental, peer, school, and community relationships. Data were analysed by means of multivariate analyses of variance and standard multiple regression analyses in order to predict risk-taking behaviour (violence, substance use, and risky sexual behaviour) from various relationship contexts (parents, peers, school, and community). Irrespective of relationship context, males portray a higher risk for all types of risky behaviour, and the more time adolescents spend with their peers, the higher their risk for engagement in risk-taking behaviour. Parental monitoring predicted a lower risk for portraying risky behaviour.     

Internet-Delivered CBT for Children with Specific Phobia: A Pilot Study

Background: Cognitive behavior therapy (CBT) has been shown to be an effective treatment for specific phobia in youth, but not all affected seek or receive treatment. Internet-delivered CBT could be a way to increase the availability of empirically supported treatments. Aims: An open trial was conducted to evaluate Internet-delivered CBT for children with specific phobia. Method: Children (N = 30) aged 8–12, and their parents, with a principal diagnosis of specific phobia were recruited through media advertisement. Participants received six weeks of Internet-delivered CBT with therapist support. The treatment was aimed for the parents and the children, with the first part being only for the parents. The primary outcome measure was the Clinician Severity Rating (CSR), and secondary measures included clinician-rated global functioning and child- and parent-reported anxiety and quality of life. All assessments were made at pretreatment, posttreatment, and three-month follow-up. Results: At posttreatment, there were significant reductions on the CSR, with a large within-group effect size (Cohen's d = 1.0) and 35% of children no longer meeting criteria for specific phobia. Self-report measures from parents and children showed significant effects on anxiety, with small to moderate effect sizes. Effects were maintained at three-month follow-up. Conclusions: Results show that Internet-delivered CBT with therapist support for children with specific phobia has the potential to reduce symptom severity. Randomized controlled trials are needed to further evaluate this treatment format.
