Impacts of Just Culture on Perioperative Nurses' Attitudes and Behaviors With Regard to Patient Safety Incident Reporting: Cross-Sectional Nationwide Survey

PurposeJust culture refers to a culture that encourages members of an organization to exchange important safety information and compensates them when they perform such information exchanges. The establishment of a just culture in hospital organizations might be an important means of enhancing patient safety incident reporting. This study aimed to investigate the impact of just culture on the attitudes and behaviors toward patient safety incident reporting in perioperative nurses. MethodsA nationwide cross-sectional survey was performed using structured questionnaires. The participants were 208 perioperative nurses in tertiary general hospitals in South Korea. Data were collected by self-reported on-line questionnaires, from August to September 2020. Data were analyzed with descriptive statistics, independent t-test, chi-square test, Fisher’s exact test, one-way ANOVA, Scheffé test, Pearson's correlation analysis, Spearman rank correlation analysis, hierarchical multiple regression, and hierarchical logistic regression using the SPSS WIN 23.0 program. ResultsHierarchical multiple regression analysis revealed that just culture explained an additional 34.5%p of the attitudes on patient safety incident reporting. Hierarchical logistic regression analysis showed that just culture was a significant predictor of behaviors regarding patient safety incident reporting (odds ratio = 2.25, p = 0.017). The final regression model accounted for 16.0% of the behaviors regarding patient safety incident reporting. ConclusionsThis study empirically shows that just culture impacted the attitudes and behaviors regarding patient safety incident reporting in perioperative nurses. This study provides an evidence about the importance of the just culture in every day nursing practice setting. Personnel and organizational efforts for improving or implementing just culture are required to ensure greater patient safety by enhancing the patient safety incident reporting of perioperative nurses in hospitals.

Personality Traits and Behavior of Students in English Class

The current study aimed to explore the domains of personality traits that significantly predicts the behavior of students in English class. In this study, the researcher selected the 200 junior high school teachers in CLuster 13 schools in Davao City as the respondents of the study. Stratified random sampling technique was utilized in the selection of the respondents. Non- experimental quantitative research design using descriptive-correlational method was employed. The data collected were subjected to the following statistical tools: Mean, Pearson Moment Product Correlation, and Linear Regression Analysis. Descriptive analysis showed that personality traits and behavior of students in English class were described as extensive. Further, correlation analysis demonstrated that there is a significant relationship between personality traits and behavior of students in English class. Evidently, linear regression analysis reflected that personality traits in terms of extraversion, conscientiousness, neuroticism, and openness was found to be a significant predictor of behavior of students in English class in Cluster 13, Davao City. In other words, personality traits significantly influence the behavior of students in English class in Cluster 13 schools in Davao City.

Assessing Trial-by-Trial Electrophysiological and Behavioral Markers of Attentional Control and Sensory Precision in Psychotic and Mood Disorders.

The current study investigated the extent to which changes in attentional control contribute to performance on a visual perceptual discrimination task, on a trial-by-trial basis in a transdiagnostic clinical sample. Participants with schizophrenia (SZ; N = 58), bipolar disorder (N = 42), major depression disorder (N = 51), and psychiatrically healthy controls (N = 92) completed a visual perception task in which stimuli appeared briefly. The design allowed us to estimate the lapse rate and the precision of perceptual representations of the stimuli. Electroencephalograms (EEG) were recorded to examine pre-stimulus activity in the alpha band (8-13 Hz), overall and in relation to behavior performance on the task. We found that the attention lapse rate was elevated in the SZ group compared with all other groups. We also observed group differences in pre-stimulus alpha activity, with control participants showing the highest levels of pre-stimulus alpha when averaging across trials. However, trial-by-trial analyses showed within-participant fluctuations in pre-stimulus alpha activity significantly predicted the likelihood of making an error, in all groups. Interestingly, our analysis demonstrated that aperiodic contributions to the EEG signal (which affect power estimates across frequency bands) serve as a significant predictor of behavior as well. These results confirm the elevated attention lapse rate that has been observed in SZ, validate pre-stimulus EEG markers of attentional control and their use as a predictor of behavior on a trial-by-trial basis, and suggest that aperiodic contributions to the EEG signal are an important target for further research in this area, in addition to alpha-band activity.

Predictors of medical staff's knowledge, attitudes and behavior of dysphagia assessment: A cross-sectional study.

This study aimed to explore the predictors of medical staff's Knowledge, Attitudes and Behavior of dysphagia assessment, to provide reference suggestions for constructing the training program and improving the rate of dysphagia assessment. This study was a cross-sectional study. A total of 353 nurses and doctors from four provinces (Guangdong, Hunan, Guangxi, and Shaanxi) who were selected by convenience sampling and invited to complete the questionnaire through WeChat, DingTalk, and Tencent instant messenger from May 23 to 31, 2022. A self-reported questionnaire was used to assess participants' Knowledge, Attitude and Behavior regarding dysphagia assessment. Participants' sociodemographic, training, and nursing experience were measured using the general information sheet and analyzed as potential predictors of medical staff's Knowledge, Attitudes and Behavior of dysphagia assessment. A multiple linear regression model was used to identify the predictors. The mean scores for Knowledge, Attitudes and Behavior of dysphagia assessments were (15.3±2.7), (35.9±4.9) and (41.4±14.4) respectively. Knowledge and Behavior of medical staff were medium, and attitude was positive. Multiple linear regression results indicated that experience in nursing patients with dysphagia, related training for dysphagia, working years in the field of dysphagia related diseases, specialized training (geriatric, swallowing and rehabilitation) and department (Neurology, Rehabilitation, Geriatrics) were significant predictors of Behavior, accounting for 31.5% of the variance. Working years in the field of dysphagia related diseases, department (Neurology, Rehabilitation, Geriatrics) and title were significant predictors of medical staff's knowledge, accounting for 7.8% of variance. Education, experience in nursing patients with dysphagia, department (Neurology, Rehabilitation, Geriatrics) and related training for dysphagia were significant predictors of medical staff's attitude, accounting for 12.9% of variance. The study findings implied that nursing experience, training, and work for patients with swallowing disorders could have positive effects on the Knowledge, Attitudes and Behavior of medical staff regarding dysphagia assessment. Hospital administrators should provide relevant resources, such as videos of dysphagia assessment, training centers for the assessment of dysphagia, and swallowing specialist nurses.

Applying the SOR framework to mitigate single-use plastic tableware consumption and why does it work? Solving the dissonance with an extended SOR framework

Although plastic pollution is a critical environmental issue worldwide and household consumption of single-use plastic tableware (SUPT) is a growing concern, research on the determinants of SUPT use is deficient. In light of the prevalent and frequent use of SUPT, the far-reaching nature of its consumption, and its distinctive health concerns, compounded by the lack of dedicated regulations, this article sheds light on the SUPT problem and strives to minimize SUPT consumption. The Stimulus-Organism-Response (SOR) framework has been extensively applied in various contexts but not yet in the context of household SUPT consumption. In this study, we aim to fill the lacuna by examining the motives behind SUPT consumption using two online questionnaires in two Western countries that are known for relatively high domestic SUPT consumption: Israel (Study 1, n = 408) and the USA (Study 2, n = 295). Our findings indicate that personal attitudes toward the plastic problem (“organism” in the SOR taxonomy) mediate the relation between plastic health problem awareness (“stimulus”) and SUPT consumption (“response”). Moreover, we identified perceived behavioral control (PBC) as a significant predictor of behavior when behavior is not under volitional control (i.e., an action against the individual's self-interest), as in the SUPT context. Therefore, we propose expanding the SOR framework with the organism comprising attitude and PBC, thus supporting the dissonance theory (double mediation). We suggest that modifying personal attitudes toward the plastic problem by enhancing plastic health problem awareness may strengthen PBC and reduce SUPT consumption. Overall, this study deepens our understanding of SUPT consumption by highlighting the importance of attitude and PBC as mechanisms that link awareness to sustainable behavior.

The Role of Attitude in the Unified Theory of Acceptance and Use of Technology: A Meta-analytic Structural Equation Modelling Study

The Unified Theory of Acceptance and Use of Technology (UTAUT) model has been widely used to explain user intention and use behavior. Past research has added attitude to the UTAUT framework to examine further how it influences technology adoption. This study utilized a combined meta-analysis and structural equation modelling [approach] to examine how the model, when extended with attitude as a variable, differs from its original UTAUT model and whether there are emerging relationships among the existing constructs. Based on 21 empirical studies that included attitude in various extended models, the results showed that attitude was a significant predictor of behavioral intention and use behavior. The study also revealed that facilitating conditions emerged as the strongest predictor of use behavior in the presence of attitude as a construct. In conclusion, while the inclusion of attitude as a separate construct in the UTAUT model has provided a more comprehensive understanding of technology adoption and usage behavior, this study showed that it did not enhance its explanatory power.

Laboratory performance prediction using virtual reality behaviometrics.

In this study, we show that virtual reality (VR) behaviometrics can be used for the assessment of compliance and physical laboratory skills. Drawing on approaches from machine learning and classical statistics, significant behavioral predictors were deduced from a logistic regression model that classified students and biopharma company employees as experts or novices on pH meter handling with 77% accuracy. Specifically, the game score and number of interactions in VR tasks requiring practical skills were found to be performance predictors. The study provides biopharma companies and academic institutions the possibility of assessing performance using an automatic, reliable, and simple alternative to traditional in-person assessment methods. Integrating the assessment into the training tool renders such laborious post-training assessments unnecessary.

Motivations for watching videos on mobile phones while driving in parking lots and while waiting at intersections in the United States

This is a two-part mixed methods study that investigated motivations for watching videos on mobile phones while driving. We make three theoretical contributions in this paper. First, we specifically examine watching videos on mobile phones while driving, whereas previous studies examine calling, texting, monitoring messages, and using apps. Second, we specifically focus on waiting at intersections and driving in parking lots; parking lots have not been studied in previous studies. Third, we incorporate perception about the law into the Theory of Planned Behavior model as a predictor of intention.The quantitative survey yielded responses measuring each variable in our extended Theory of Planned Behavior model. We found that although people don’t watch videos on their phones while driving as much as they text or converse, the rates of watching are disturbingly high (41% watch at intersections). The intention to watch while driving is a significant predictor of behavior, and attitude is a significant predictor of intention in both scenarios. Moral norms are significant predictors of intention in the parking lot scenario. Nearly half (48%) of drivers don’t know their state laws regarding mobile phone use while driving. Neither knowledge about state law with respect to watching videos on mobile phones while driving nor the actual state law about using handheld devices while driving is a significant predictor of the intention to watch videos while driving. The qualitative survey yielded open-ended responses on drivers’ salient beliefs about watching videos on mobile phones while driving. We propose using a multitude of laws to reduce mobile phone use while driving, and requiring drivers to take a short course on distracted driving.

COVID-19 Preventive Behaviors and Related Beliefs Among Diabetics: The Use of Protection Motivation Theory

Background: Recent data from coronavirus disease 2019 (COVID-19) confirm that diabetes, along with advanced age, is an important risk factor for adverse prognosis. Therefore, the present study aimed to determine the status of COVID-19 prevention behaviors and related beliefs among diabetic patients in Hamadan province using protection motivation theory (PMT). Methods: This cross-sectional descriptive study was conducted from April to September 2020. The research population included all diabetics, of whom 355 patients, who referred to an adult endocrinologist in Hamadan, were selected using the convenience sampling method. The data collection tool was a researcher-made questionnaire with demographic variables and PMT constructs. Data were analyzed by SPSS 22 using descriptive statistics, correlation, and logistic regression. Results: According to the result, the PMT construct explained 15% of the variance in the frequency of the intention to perform preventive behaviors. Perceived sensitivity (β=-0.128), perceived response efficiency (β=0.140), and perceived response cost (β=0.386) were the best significant predictors of behavior (P<0.05). There was a significant relationship between gender (P<0.001), marital status (P<0.001), and level of education (P=0.040) in observing preventive behaviors. Conclusion: It is necessary to enhance the levels of awareness and self-efficacy of diabetic patients to reduce fear in this at-risk group. Further, it is appropriate to use PMT to promote preventive behaviors.

How COVID-19 stole Christmas: How the pandemic shifted the calculus around social media Self-Disclosures

During the COVID-19 pandemic, social media use increased significantly, and news media also reported increased levels of social shaming for behaviors that were now deemed high-risk for spreading or contracting the virus. This study examines how this pandemic-afflicted environment changed what and how individuals disclosed online during the 2020 holiday season. Using data collected at two time periods in December 2020 from Facebook and Instagram users, the data show that social calculus constructs comprise most of the significant predictors for online self-disclosure; evaluation apprehension is also a significant moderator. In a post-hoc analysis with 2019 disclosure data, this study finds that most of the significant predictors of behavior arise from privacy calculus, providing evidence of a shift in the salient predictors of online self-disclosure. The implications of this research to businesses and future research directions are discussed.

Explaining adults’ mental health help-seeking through the lens of the theory of planned behavior: a scoping review

BackgroundDespite evidence-based efficacy, mental health services are underutilized due to low rates of help-seeking, leaving unmet mental health needs a global concern. The Theory of Planned Behavior (TPB) has been applied to understand the help-seeking process and in the development of behavior change interventions. The aim of this scoping review was to map the literature on the TPB as applied to mental health help-seeking in adults aged >18 years.MethodsThis scoping review was conducted based on the methodology presented by Arksey and O’Malley (2005). Six databases (CINAHL, PsycINFO, MEDLINE, ProQuest Health and Medicine, ProQuest Dissertations and Theses, Web of Science) and two grey literature sources (OpenGrey, Google Scholar) were systematically searched in February 2018 and updated in March 2020. Studies that explicitly discussed the TPB in the context of mental health help-seeking were initially selected; only studies that explored formal help-seeking for mental health problems and were published in English were retained. Data were extracted using Microsoft Excel.ResultsInitially, 8898 records were identified. Of these, 49 met the selection criteria and were included: 32 were journal articles and 17 were theses. Forty-three papers reported on non-intervention studies and seven articles reported on TPB-based interventions. Most studies (n = 39) identified predictors of help-seeking intentions. Attitudes and perceived behavioral control were significant predictors of intentions in 35 and 34 studies, respectively. Subjective norms were a significant predictor of intentions in 23 studies. Few studies aimed to predict help-seeking behavior (n = 8). Intentions and perceived behavioral control were significant predictors of behavior in seven and six studies, respectively. Only six TPB-based interventions were identified, all used digital technology to influence help-seeking, with mixed results.ConclusionsThe present scoping review identified a considerable evidence base on the TPB for predicting mental health help-seeking intentions. Attitudes and perceived behavioral control were frequently found to be significant predictors of help-seeking intentions. Knowledge on the TPB for predicting mental health help-seeking behavior, and on TPB-based interventions, is limited. Thus, the role of the TPB in developing help-seeking interventions remains unclear. Recommendations are presented to address such research gaps and inform policy and practice.

COVID-19 and the Locavores: Investigating the Drivers of US Consumer Preferences for Apples

This study provides insights and best-practice recommendations for marketing managers in the US food retail sector and the horticultural industry. An online survey distributed via a crowdsourcing platform in 2021 aimed to explore the factors that explained the intentions of US consumers to purchase locally grown apples. The Theory of Planned Behavior was used as a conceptual framework to shape the proposed model. The results emphasize the importance of behavioral, normative and control beliefs as important factors towards attitudes. Subjective norms and perceived behavioral control were also found to be key drivers in understanding behavioral intention. All concepts, with the exception of perceived behavioral control, were found to be significant behavioral predictors.

Investigating values of green marketing tools in predicting tourists’ eco-friendly attitudes and behavior

ABSTRACT The environment often suffers harmful consequences caused by the irresponsible behavior of individuals and businesses. In this sense, neither the tourism industry nor tourists are spared these accusations. Therefore, tourism literature highlights the significance of exploring tourists’ eco-friendly attitudes and behavior and determinants of the formation of both eco-friendly attitudes and behavior. Additionally, consumer literature sheds light on how important green marketing is in changing consumers’ behavior and leading them towards greener consumption behavior. Nevertheless, existing tourism literature on the role of green marketing approaches in predicting tourists’ eco-friendly attitudes and behavior is quite scarce. Hence, the principal aim of the research was to investigate whether the green marketing tool – green packaging and branding, influences tourists’ eco-friendly attitudes and behavior. Additionally, the present paper focused on tourists’ preferences toward green packaging. In an effort to establish this, survey research was conducted among 368 Serbian tourists. The results showed that green packaging and branding positively shape tourists eco-friendly attitudes and behavior, and that attitudes represent significant predictor of behavior. The valuable contribution of this paper lies in practical implications for destination marketers, which highlight how the promotion of green products in tourism could enhance potential tourists’ eco-friendly attitudes and behavior.

Observations of Child Behaviors and Responsivity during Sensory Friendly Community Events

Sensory-friendly time (SFT) events modify community environments and activities to improve leisure participation for children with sensory processing differences, and are becoming increasingly popular. However, little evidence exists examining if SFT events successfully support community engagement for this population. An urban university and neighboring children’s museum designed multi-sensory SFT events for the community. This study explored what types and intensities of multi-sensory activities predicted behavioral responses from children with atypical sensory processing. A Child Engagement Observation Log documented activity interaction, affect, responsivity (arousal) and emotional response of children participating in SFT activities. Poisson regression models determined if sensory properties (sensory domain and intensity) of different activities significantly predicted observable behavior. Activities with a medium sound intensity, sight intensity and level of complexity; medium intensity of sight, touch, and complexity; and medium levels of movement and complexity were significant predictors of behaviors (p<.05). Results can guide future community SFT programming.

Staying Pressure Injury Free: The Role of Modifiable Behaviors

ObjectiveTo investigate the association of behavioral factors with retrospective reports of staying free from pressure injuries (PIs) during a 12-month period for people with chronic spinal cord injury (SCI). DesignCross-sectional survey. SettingData collection was completed at an academic medical center in the Southeastern United States in collaboration with a specialized treatment center and 2 public health registries that use population-based approaches to identify all incident cases of SCI within the state. ParticipantsThe participant cohort was composed of 3817 adults (N=3817) with traumatic SCI of at least 1-year duration. InterventionsNot applicable. Main Outcome MeasuresSelf-reported recall of staying PI-free for 12 months vs having 1 or more PIs. ResultsAmong the 3817 participants, 74% were male, 76% were non-Hispanic White, and mean age was 48 years, with an average of 12 years post SCI. Based on self-report assessment, 67% reported being PI-free in the past year. After controlling for the demographic and injury characteristics, we found that those in the clinical cohort and those who reported healthy diets and planned exercise at least once a week were more likely to be PI-free; being underweight and high frequency of prescription medication use for spasticity, pain, and depression were negatively associated with being PI-free. Smoking, alcohol use, nonmedical substance use, and prescription medication misuse were not statistically significant in the multivariate model. ConclusionsThere are several significant behavioral predictors of being PI-free, and consideration of these factors may be used to develop tailored strategies to promote healthy skin maintenance and the prevention of multiple, severe, and recurrent PI.

Out of Sight, Out of Mind or Just Something in the Way? Visual Barriers Do Not Reduce Intraspecific Agonism in an All-Male Group of Nile Crocodiles (Crocodylus niloticus).

Simple SummaryThe behavior of animals living in zoos and aquariums is influenced by the exhibits they live in, similar to how the behavior of animals in nature is influenced by the ecosystem they inhabit. In zoos and aquariums, changes in exhibit design can be implemented to modify the behavior of animals to ensure they are experiencing optimal welfare. Here, we evaluated if the addition of visual barriers—physical barriers placed at the surface of the water—reduce aggression amongst male Nile crocodiles living in a zoo. Both short- and long-term monitoring found that visual barriers did not reduce aggression within the group. While ineffective at reducing aggression, this study represents the first evaluation of exhibit design in relation to the behavior of a crocodilian species in a zoo or aquarium setting. As a commonly managed taxa in zoos and aquariums, it is imperative that their behavior and welfare are assessed systematically. We hope the methodologies and learnings from this study encourage future study of crocodilian behavior and welfare.Here, we evaluated if visual barriers could reduce intraspecific agonism in an all-male group of Nile crocodiles (Crocodylus niloticus) living in a zoo. Crocodiles were monitored for nearly 100 h, and four “hotspots” of aggression within their exhibit were identified. Within these four locations, visual barriers were placed at the surface of the water with the goal of reducing agonism by targeting sight lines associated with their species-typical minimum exposure posture, where crocodiles submerge their body but maintain facial sensory organs above the water line. Crocodile behavior was then monitored for 226 h, evaluating both short- and long-term effects of the visual barriers. In both observation periods, intraspecific agonism was unaffected by visual barriers. However, crocodiles were more likely to be on land and closer together, after the barriers were installed, showing the barriers affected nonagonistic behaviors. Monitoring of such unintended effects is significant to ensure no welfare concerns are created in any exhibit or husbandry modification attempt. Additionally, time of day and temperature were significant predictors of behavior, highlighting the importance of such factors in the analysis of reptilian behavior. While ineffective at reducing agonism, this is the first published study evaluating exhibit design and behavior of crocodilians in zoos and aquariums. The methodologies and findings here should provide useful information for future behavioral and welfare studies of this understudied taxa.

Drivers of Pigeon Pea Consumption Among School-Aged Children in Central Tanzania

Background: Protein energy malnutrition (PEM) and iron deficiencies (ID) are of major public health concern in Tanzania including among school-aged children. PEM and ID in early childhood have serious, long-term consequences because they impede motor, sensory, social and emotional development, growth retardation, poor cognitive development, learning disability of children, lowered resistance to infectious diseases, and reduced physical work capacity. The objective of this study was to elucidate the drivers of pigeon pea consumption among school-aged children in Dodoma district, Central Tanzania. Understanding these drivers would be useful in promoting pigeon pea consumption among school-aged children as one of the strategies to increase dietary protein and iron intake.Methods: This study was a cross-sectional study in which data were collected using a questionnaire based on a combination of the Theory of Planned Behavior and Health Belief Model. The data were collected from caregivers (n = 138) in four villages in Kongwa district, Dodoma region, Central Tanzania. We used correlations and multiple regressions to assess associations between constructs and identify predictive constructs. Mann–Whitney U tests were used for score comparisons with a significant p-value set at &amp;lt;0.10.Results: Health value was significantly correlated with health behavior identity (rs = 0.63, p &amp;lt; 0.001) and also significantly predicted health behavior identity (rs = 0.49, p = 0.001). The constructs cues to action and control belief were significantly associated with intention (β = −0.41, p = 0.059 and β = 0.06, p = 0.019 respectively). Finally, we observed that intention was a significant predictor of behavior (β = 1.38, p = 0.001). We also observed a significant negative interaction between perceived barriers and intention to consume pigeon pea (β = −0.04, p = 0.006), indicating that perceived barriers limit intention to consume pigeon pea.Conclusion and Implication: Our findings indicate that when the caregiver places increased importance on preventing her school-aged child from being iron or protein deficient or indeed anemic (health value), it results in a positive evaluation of the effectiveness of giving pigeon pea to address these nutrient deficiencies. Programs and efforts aimed at promoting pigeon pea consumption should focus on educating caregivers on iron and protein deficiency and the role that pigeon pea could play in addressing these. However, perceived barriers such as pest infestation during storage need to be addressed to increase pigeon pea consumption. The involvement of post-harvest management specialists is therefore crucial. Along with this, increasing productivity and crop management is also crucial to ensure year-round affordable supply of pigeon pea.

Predicting Young Adults’ Intentions and Involvement in Alcohol-Influenced Aquatic Activity

Globally, alcohol consumption is a public health issue and a risk factor for drownings among young adults. While studies have identified a prominence of alcohol in youth drownings, little is known about the factors that influence young adults’ involvement in alcohol-influenced aquatic activity. The current study aimed to identify the predictors of young adults’ intention to participate, and past participation, in alcohol-influenced aquatic activity. A reliable and valid survey, informed by the Theory of Planned Behavior, was distributed to young adults (aged 18-24 years) educated in the UK and Australia. Cumulative odds ordinal logistic regressions with proportional odds were conducted to establish predictors. Overall, 182 participants completed the survey. Subjective norms (Wald χ2 (2) = 8.43, p = .015), cognitive attitudes (Wald χ2 (2) = 6.40, p = .041) and previous involvement (χ2 (1) = 8.98, p = .003) were significant predictors of intention, whilst the influence of friends (Wald χ2 (2) = 10.99, p = .004) and intention (Wald χ2 (2) = 10.80, p = .005) were significant predictors of behavior. Practitioners should enhance risk awareness and norm perceptions in prevention programs to encourage informed decision making in social aquatic situations.

Smartphone use among young drivers: Applying an extended Theory of Planned Behaviour to predict young drivers’ intention and engagement in concealed responding

Young drivers, aged 17–25 years, are more likely than other age groups to access social interactive technologies (e.g., Snapchat, Facebook) on their smartphones while driving. Many of these young drivers do so in a concealed manner, thereby diverting their eyes from the road for extended periods and increasing their crash risk. In accordance with previous research, an extended Theory of Planned Behaviour (TPB) was applied in this survey study to investigate psychosocial predictors of young drivers’ intention, and behaviour, of responding to social interactive technology on a smartphone in a concealed manner. Participants (N = 154) resided in Australia, were aged 17–25 years, owned a provisional or an open licence, and owned a smartphone. Participants completed two online surveys administered 1-week apart. The first survey measured intention and assessed the TPB standard constructs of attitude, subjective norm, and perceived behavioural control, as well as the additional constructs of anticipated action regret, anticipated inaction regret, and problematic mobile phone usage. The first survey also assessed whether there were any differences in the salient beliefs (elicited in a previous study) about smartphone use between high and low intenders to engage in this behaviour. The second survey measured engagement in the behaviour of responding in a concealed manner in the previous week. Hierarchical multiple regression analyses showed the standard TPB accounted for 69% of variance in intention, and a further 4% was accounted for by the extended constructs. In the final model, all variables, except anticipated inaction regret, were significant predictors of intention. Intention was the only significant predictor of behaviour. A series of MANOVAs found significant differences in the salient belief items between high and low intenders (e.g., high intenders were more likely to believe that friends/peers and other drivers would approve of them engaging in this behaviour). These key findings can be used as focal points for public education messages to persuade young drivers to reduce the frequency of their smartphone use, which is vital to improve road safety for all users.

Maternal depression and infant social withdrawal as predictors of behaviour and development in vertically HIV-infected children at 3.5 years

ABSTRACT Background In low- and middle-income countries, there is a high prevalence of post-partum depression and it is often associated with HIV status. Maternal depression negatively affects mothering and can lead to social withdrawal in infants. Maternal depression and infant social withdrawal can have deleterious long-term effects on children’s behaviour and neurodevelopmental trajectories. Aim To investigate whether maternal depression and infant social withdrawal at 10–12 months post-partum were significant predictors of child behaviour and development at 42 months. Method Seventy-four mother–infant dyads living with HIV were followed in a prospective, longitudinal design. Mothers were assessed for depression using the Center for Epidemiologic Studies Depression scale (CES-D). Infant social withdrawal was assessed by the modified Alarm Distress Baby Scale (m-ADBB), and development and behaviour were evaluated by the Griffiths Mental Development Scales (GMDS) and the Child Behavior Checklist (CBCL), respectively. Results Maternal depression explained 4.8% of the variance in child behaviour (β = 0.98, t = 2.05, p < 0.05) and 10.3% of the variance in development (β = −0.30, t = −2.66, p < 0.05). Infant social withdrawal was not a significant predictor of behaviour (β = 3.27, t = 1.36, p = 0.18), but it did uniquely explain 7% of the variance in development (β = −1.32, t = −2.48, p < 0.05). Conclusion In the context of HIV, screening for maternal depression and the quality of mother–infant interactions are important (especially in the 1st year post-partum), given the significant long-term impact they have on behaviour and neurodevelopment.
