1026 to 1050 of 1,483Listening to the rural health workers in Papua New Guinea - the social factors that influence their motivation to work.
Despite rural health services being situated and integrated within communities in which people work and live, the complex interaction of the social environment on health worker motivation and performance in Low Middle Income Countries has been neglected in research. In this article we investigate how social factors impact on health worker motivation and performance in rural health services in Papua New Guinea (PNG). Face-to-face in-depth interviews were conducted with 33 health workers from three provinces (Central, Madang, and Milne Bay) in PNG between August and November 2009. They included health extension officers, community health workers and nursing officers, some of whom were in charge of the health centres. The health centres were a selection across church based, government and private enterprise health facilities. Qualitative analysis identified the key social factors impacting …

An empirical test of forgiveness motives' effects on employees' health and well-being.
Two critical-incident studies were conducted to determine what motivates employees to forgive (or reconcile) with coworkers who offend them. Data from the first study's exploratory factor analysis revealed five types of motives for forgiveness: apology, moral, religious, relationship, and lack of alternatives. Data from the second study on a different sample confirmed the five-factor structure, and structural equation modeling demonstrated differential relationships between the five motives and the outcome variables, stress and health. Individuals who claimed to have forgiven because they believed they had no other alternatives, or who forgave because they believed a higher power (religious) required it, were more likely to report greater stress and poorer health. Positive outcomes of forgiveness were discovered for those employees who forgave because they believed it was the right (mora…

Adherence as a determinant of effectiveness of internet cognitive behavioural therapy for anxiety and depressive disorders.
Since 2009, the Clinical Research Unit for Anxiety and Depression (CRUfAD) has been providing primary care clinicians with internet cognitive behaviour therapy (iCBT) courses to prescribe to patients. Although these courses have demonstrated efficacy in research trials, adherence in primary care is less than half that of the research trials. The present studies pose three questions: first, do course non-completers drop out because of lack of efficacy? Second, can changes in delivery (e.g. adding choice, reminders and financial cost) improve adherence? Last, does clinician contact improve adherence? The results showed that non-completers derive benefit before dropping out; that adding reminders, choice of course and timing, and financial cost can significantly improve adherence; and that clinician contact during the course is associated with increased adherence. It is concluded that impro…

Setting: Five in-patient and out-patient tuberculosis (TB) care facilities in two regions of Russia.
Objective: To identify barriers and motivators to the use of infection control measures among Russian TB health care workers.
Design: In this qualitative study, a convenience sample of 96 health care workers (HCWs) was used to generate 15 homogeneous focus groups, consisting of physicians, nurses, and laboratory or support staff.
Results: Barriers and motivators related to knowledge, attitudes and beliefs, and practices were identified. The three main barriers were 1) knowledge deficits, including the belief that TB was transmitted by dust, linens and eating utensils; 2) negative attitudes related to the discomfort of respirators; and 3) practices with respect to quality and care of respirators. Education and training, fear of infecting loved ones, and fear of punishment were the main mot…

Gender-related clinical and neurocognitive differences in individuals seeking treatment for pathological gambling.
Objectives: Understanding variations in disease presentation in men and women is clinically important as differences may reflect biological and sociocultural factors and have implications for selecting appropriate prevention and treatment strategies. The aim of this study was to investigate clinical and cognitive differences in treatment-seeking people with pathological gambling as a function of gender.
Materials and methods: 501 adult subjects (n = 274 [54.7%] females) with DSM-IV pathological gambling presenting for various clinical research trials over a 9-year period were assessed in terms of sociodemographics and clinical characteristics. A subset (n = 77) had also undertaken neuropsychological assessment with the Stop-signal and set-shift tasks.
Results: PG in females was associated with significantly worse disease severity, elevated mood and anxiety scores, and history of affectiv…

Nucleus accumbens response to food cues predicts subsequent snack consumption in women and increased body mass index in those with reduced self-control.
Individuals have difficulty controlling their food consumption, which is due in part to the ubiquity of tempting food cues in the environment. Individual differences in the propensity to attribute incentive (motivational) salience to and act on these cues may explain why some individuals eat more than others. Using fMRI in healthy women, we found that food cue related activity in the nucleus accumbens, a key brain region for food motivation and reward, was related to subsequent snack food consumption. However, both nucleus accumbens activation and snack food consumption were unrelated to self-reported hunger, or explicit wanting and liking for the snack. In contrast, food cue reactivity in the ventromedial prefrontal cortex was associated with subjective hunger/appetite, but not with consumption. Whilst the food cue reactivity in the nucleus accumbens that predicted snack consumption was…

Using psychological theory to inform methods to optimize the implementation of a hand hygiene intervention.
Background: Careful hand hygiene (HH) is the single most important factor in preventing the transmission of infections to patients, but compliance is difficult to achieve and maintain. A lack of understanding of the processes involved in changing staff behaviour may contribute to the failure to achieve success. The purpose of this study was to identify nurses' and administrators' perceived barriers and facilitators to current HH practices and the implementation of a new electronic monitoring technology for HH.
Methods: Ten key informant interviews (three administrators and seven nurses) were conducted to explore barriers and facilitators related to HH and the impact of the new technology on outcomes. The semi structured interviews were based on the Theoretical Domains Framework by Michie et al. and conducted prior to intervention implementation. Data were explored using an inductive qual…

Motivational versus metabolic effects of carbohydrates on self-control.
Self-control is critical for achievement and well-being. However, people's capacity for self-control is limited and becomes depleted through use. One prominent explanation for this depletion posits that self-control consumes energy through carbohydrate metabolization, which further suggests that ingesting carbohydrates improves self-control. Some evidence has supported this energy model, but because of its broad implications for efforts to improve self-control, we reevaluated the role of carbohydrates in self-control processes. In four experiments, we found that (a) exerting self-control did not increase carbohydrate metabolization, as assessed with highly precise measurements of blood glucose levels under carefully standardized conditions; (b) rinsing one's mouth with, but not ingesting, carbohydrate solutions immediately bolstered self-control; and (c) carbohydrate rinsing did not incr…

Patient and impatient punishers of free-riders.
Costly punishment of cheaters who contribute little or nothing to a cooperating group has been extensively studied, as an effective means to enforce cooperation. The prevailing view is that individuals use punishment to retaliate against transgressions of moral standards such as fairness or equity. However, there is much debate regarding the psychological underpinnings of costly punishment. Some authors suggest that costly punishment must be a product of humans' capacity for reasoning, self-control and long-term planning, whereas others argue that it is the result of an impulsive, present-oriented emotional drive. Here, we explore the inter-temporal preferences of punishers in a multilateral cooperation game and show that both interpretations might be right, as we can identify two different types of punishment: punishment of free-riders by cooperators, which is predicted by patience (fut…

The prefrontal cortex (PFC) is thought to participate in high-level control of the generation of behaviours (including the decision to execute actions); indeed, imaging and lesion studies in human beings have revealed that PFC dysfunction can lead to either impulsive states with increased tendency to initiate action, or to amotivational states characterized by symptoms such as reduced activity, hopelessness and depressed mood. Considering the opposite valence of these two phenotypes as well as the broad complexity of other tasks attributed to PFC, we sought to elucidate the PFC circuitry that favours effortful behavioural responses to challenging situations. Here we develop and use a quantitative method for the continuous assessment and control of active response to a behavioural challenge, synchronized with single-unit electrophysiology and optogenetics in freely moving rats. In recordi…

Development of a conceptual model of adherence to oral anticoagulants to reduce risk of stroke in patients with atrial fibrillation.
Background: Oral anticoagulant (OA) medication is the recommended therapy for reducing the risk of thromboembolic complications in patients with atrial fibrillation (AF), and warfarin is the medication most frequently used. However, nonadherence associated with OA medications may lead to considerable health risks. A conceptual model of OA medication adherence in patients with AF could clarify factors affecting adherence, thereby assisting in the development and structuring of adherence-promotion programs. To our knowledge, such a model, driven by information obtained directly from patients, has never been developed.
Objective: To develop a conceptual model of adherence to OA medication based on a literature review and patient feedback via qualitative research among patients with AF.
Methods: A literature search was conducted of English-language articles published between the years 2005 a…

Conciliatory gestures facilitate forgiveness and feelings of friendship by making transgressors appear more agreeable.
The authors examined how conciliatory gestures exhibited in response to interpersonal transgressions influence forgiveness and feelings of friendship with the transgressor. In Study 1, 163 undergraduates who had recently been harmed were examined longitudinally. Conciliatory gestures exhibited by transgressors predicted higher rates of forgiveness over 21 days, and this relationship was mediated by victims' perceptions of their transgressors' Agreeableness. Study 2 was an experiment including 145 undergraduates who experienced a breach in trust from an anonymous partner during an iterated prisoner's dilemma. When transgressors apologized and offered financial compensation, participants reported higher levels of forgiveness and feelings of friendship when compared to a control condition and an aggravating condition. The effects of apology/compensation on forgiveness and perceived friendsh…

When people want what others have: the impulsive side of envious desire.
Envy is the unpleasant emotion that can arise when people are exposed to others with superior possessions. Common wisdom and scholarly opinion suggest that when people experience envy they may be motivated to obtain the others' superior possession. Despite the vast interpersonal, societal, and economical consequences attributed to this potential aspect of envious responding, experimental demonstrations of the affective and behavioral consequences of envy-inducing situations are scarce. We propose that social comparisons with better-off others trigger an impulsive envious response that entails a behavioral tendency to strive for their superior good. However, given that the experience of envy is painful, self-threatening, and met with social disapproval, people typically attempt to control their envious reactions. Doing so requires self-control capacities, so that envious reactions may onl…

Clinical profiles as a function of level and type of impulsivity in a sample group of at-risk and pathological gamblers seeking treatment.
Level and type of impulsivity are essential variables to be taken into consideration during the initial evaluation of a pathological gambler. The aim of this study was to measure the score for 4 impulsivity-related traits (Urgency, (lack of) Premeditation, (lack of) Perseverance and Sensation seeking) in a sample group of at-risk and pathological gamblers, and to highlight any links with certain elements of clinical data. The UPPS Impulsive Behaviour Scale was administered to 84 problem gamblers seeking treatment. The severity of gambling disorders was evaluated using the diagnostic criteria of the DSM-IV. Psychiatric and addictive comorbidities were also explored. The results indicated that the score for the Urgency facet had a positive correlation with the severity of gambling disorders. It appeared that participants displayed different clinical profiles according to the level and type…

Mind-wandering in younger and older adults: converging evidence from the Sustained Attention to Response Task and reading for comprehension.
One mechanism that has been hypothesized to contribute to older adults' changes in cognitive performance is goal neglect or impairment in maintaining task set across time. Mind-wandering and task-unrelated thought may underlie these potential age-related changes. The present study investigated age-related changes in mind-wandering in three different versions of the Sustained Attention to Response Task (SART), along with self-reported mind-wandering during a reading for comprehension task. In the SART, both younger and older adults produced similar levels of faster reaction times before No-Go errors of commission, whereas, older adults produced disproportionate post-error slowing. Subjective self-reports of mind-wandering recorded during the SART and the reading task indicated that older adults were less likely to report mind-wandering than younger adults. Discussion focuses on cognitive …

Objective: To examine the effects of marital status and marital satisfaction on survival after coronary artery bypass grafting (CABG).
Methods: Participants were 225 people who had CABG between 1987 and 1990. Marital status at the time of surgery and marital satisfaction 1 year after surgery were used to predict survival 15 years after surgery.
Results: Married people were 2.5 times (p < .001) more likely to be alive 15 years after CABG than those who were not married. This finding was true for men and women, although the result for women was marginally significant adjusting for age. Those in high-satisfaction marriages were 3.2 times (p < .003) more likely to be alive 15 years after CABG compared with those reporting low marital satisfaction. Highly satisfied men were 2.7 times (p < .03) and highly satisfied women were 3.9 times (p < .15) more likely to be alive adjusting for age. Altho…

Beedie CJ, Lane AM (2012)MEDLINE-indexed journal, not yet read by usPersonality and social psychology review : an official journal of the Society for Personality and Social Psychology, Inc85 citations The role of glucose in self-control: another look at the evidence and an alternative conceptualization.
The strength model suggests that self-control relies on a limited resource. One candidate for this resource is glucose. Counter to the proposals of the glucose hypothesis, this study argues that the resource issue is one of allocation, not of limited supply. It addresses the argument from three perspectives: the evolution of mental processes at the species level, the adaptation of these same processes at the individual level, and the physiology of glucose transport. It is argued here that the brain has both sufficient resources and resource delivery mechanisms with which to support self-control but that these resources are allocated in accordance with personal priorities. As an alternative to the limited resource model, the current study proposes a resource-allocation model of self-control and presents several testable hypotheses.

Modulatory effects of two novel agonists for serotonin receptor 7 on emotion, motivation and circadian rhythm profiles in mice.
Serotonin receptor 7, i.e. 5-HT(7) protein coded by Htr7 gene, was discovered in supra-chiasmatic nucleus (SCN) of the hypothalamus but is widespread in the forebrain. Studies have shown that this receptor is involved in learning/memory, regulation of mood and circadian rhythms. The modulatory effects of two novel agonists, LP-211 and LP-378, were assessed in male adult CD-1 mice with a battery of behavioral tests. Exp. 1 (Black/White Boxes, BWB: Adriani et al., 2009) and Exp. 2 (Dark/Light, D/L; Novelty-seeking, N-S) show: a) that LP-211 administration (acutely, at a 0.25 mg/kg dose i.p.) increases locomotion and BWB exploration; b) that the time spent away from an aversive, lit chamber (i.e., stress-induced anxiety) and in a new environment (i.e., novelty-induced curiosity) are both reduced. Sub-chronic LP-211 (at a 2.5 mg/kg dose i.p.) reveals a sensitization of locomotor-stimulant pr…

You owe it to yourself: boosting retirement saving with a responsibility-based appeal.
Americans are not saving enough for retirement. Previous research suggests that this is due, in part, to people's tendency to think of the future self as more like another person than like the present self, making saving feel like giving money away rather than like investing in oneself. Using objective employer saving data, a field experiment capitalized on this phenomenon to increase saving. It compared the effectiveness of a novel message--one appealing to people's sense of "social" responsibility to their future selves--with a more traditional appeal to people's sense of rational self-interest. The social-responsibility-to-the-future-self message resulted in larger increases in saving than the self-interest message, but only to the extent that people felt a strong "social" connection to their future selves. These results broaden our understanding of the psychology of moral responsibil…

This article proposes an evolutionary model of risky behavior in adolescence and contrasts it with the prevailing developmental psychopathology model. The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations. The current article articulates 5 key evolutionary insights into risky adolescent behavior: (a) The adolescent transition is an inflection point in development of social status and reproductive trajectories; (b) interventions need to address the adaptive functions of risky and aggressive behaviors like bullying; (c) risky adolescent behavior adaptively calibrates over development to match both harsh and unpredictable environmental conditions; (d) understanding evolved sex …

Tailored skills training for practitioners to enhance assessment of prognostic factors for persistent and disabling back pain: four quasi-experimental single-subject studies.
The well-known gap between guidelines and behaviour in clinical practice calls for effective behaviour change interventions. One example showing this gap is physiotherapists' insufficient assessment of psychosocial prognostic factors in back pain (i.e., yellow flags). The present study aimed to evaluate an educational model by performing a tailored skills training intervention for caregivers and studying changes over time in physiotherapists' assessment of prognostic factors in telephone consultations. A quasi-experimental single-subject design over 36 weeks was used, with repeated measurements during baseline, intervention, and postintervention phases. Four physiotherapists in primary health care audiorecorded a total of 63 consultations with patients. The tailored intervention included individual goal setting, skills training, and feedback on performance. The primary outcome was the nu…

Everyday temptations: an experience sampling study of desire, conflict, and self-control.
How often and how strongly do people experience desires, to what extent do their desires conflict with other goals, and how often and successfully do people exercise self-control to resist their desires? To investigate desire and attempts to control desire in everyday life, we conducted a large-scale experience sampling study based on a conceptual framework integrating desire strength, conflict, resistance (use of self-control), and behavior enactment. A sample of 205 adults wore beepers for a week. They furnished 7,827 reports of desire episodes and completed personality measures of behavioral inhibition system/behavior activation system (BIS/BAS) sensitivity, trait self-control, perfectionism, and narcissistic entitlement. Results suggest that desires are frequent, variable in intensity, and largely unproblematic. Those urges that do conflict with other goals tend to elicit resistance,…

Looking on the bright side: children's knowledge about the benefits of positive versus negative thinking.
Five- to 10-year-olds (N = 90) listened to 6 illustrated scenarios featuring 2 characters that jointly experience the same positive event (and feel good), negative event (and feel bad), or ambiguous event (and feel okay). Afterward, one character thinks a positive thought and the other thinks a negative thought. Children predicted and explained each character's emotions. Results showed significant development between 5 and 10 years in children's understanding that thinking positively improves emotions and thinking negatively makes one feel worse, with earliest knowledge demonstrated when reasoning about ambiguous and positive events. Individual differences in child and parental optimism and hope predicted children's knowledge about thought-emotion connections on some measures, including their beliefs about the emotional benefits of thinking positively in negative situations.

Fighting food temptations: the modulating effects of short-term cognitive reappraisal, suppression and up-regulation on mesocorticolimbic activity related to appetitive motivation.
The premise of cognitive therapy is that one can overcome the irresistible temptation of highly palatable foods by actively restructuring the way one thinks about food. Testing this idea, participants in the present study were instructed to passively view foods, up-regulate food palatability thoughts, apply cognitive reappraisal (e.g., thinking about health consequences), or suppress food palatability thoughts and cravings. We examined whether these strategies affect self-reported food craving and mesocorticolimbic activity as assessed by functional magnetic resonance imaging. It was hypothesized that cognitive reappraisal would most effectively inhibit the mesocorticolimbic activity and associated food craving as compared to suppression. In addition, it was hypothesized that suppression would lead to more prefrontal cortex activity, reflecting the use of more control resources, as compa…
