Knowledge and the Prediction of Behavior: The Role of Information Accuracy in the Theory of Planned Behavior

The usefulness of a combined protection motivation and self-efficacy theory as a model of health enhancement was investigated via a persuasive communications paradigm. Self-efficacy expectancy, outcome expectancy (i.e., perceived response efficacy) and outcome value (i.e., perceived social value) of a health-enhancing behavior were manipulated. As predicted, both self-efficacy expectancy and response efficacy had significant main effects on subjects' intentions to perform the health-enhancing behavior. Outcome value had no significant effect on behavioral intentions. Correlational data indicated that response efficacy was the best single predictor of intentions and that self-efficacy expectancy was also a significant predictor of intentions. Outcome value added no predictability. These results support the utility of the combined protection motivation and self-efficacy theory as a model of health enhancement.     

The role of parenting and dopamine D4 receptor gene polymorphisms in children's inhibitory control

Temperamental effortful control has important implications for children's development. Although genetic factors and parenting may influence effortful control, few studies have examined interplay between the two in predicting its development. The current study investigated associations between parenting and a facet of children's effortful control, inhibitory control (IC), and whether these associations were moderated by whether children had a 7‐repeat variant of the DRD4 exon III VNTR. A community sample of 409 3‐year‐olds completed behavioural tasks to assess IC, and observational measures of parenting were also collected. Negative parenting was associated with lower child IC. The association between children's IC and positive parenting was moderated by children's DRD4 7‐repeat status, such that children with at least one 7‐repeat allele displayed lower IC than children without this allele when positive parenting was lower. These effects appeared to be primarily influenced by parent support and engagement. Results extend recent findings suggesting that some genetic polymorphisms may increase vulnerability to contextual influences.     

‘Big Five’ personality dimensions and social attainment: Evidence from beyond the campus

Research on the contribution of personality traits to attainment has focused heavily on grades among college students. Conscientiousness emerges consistently as the most powerful personality dimension. However, while university students are a convenient group to study, there remain questions about the generalizability, and utility of examining the link between personality and attainment, in a group that consists mainly of educational high-achievers who have not yet earned an income. In this study, data were instead drawn from a more diverse and representative sample gathered in the British National Child Development Study (NCDS). Regression analyses indicated that, in the general population compared to student samples, Openness and Emotional Stability are stronger predictors of educational attainment and earnings than conscientiousness.     

The role of brain-derived neurotrophic factor genotype, parental depression, and relationship discord in predicting early-emerging negative emotionality

The brain-derived neurotrophic factor (BDNF) gene is a plausible candidate for early-emerging negative emotionality (NE), and evidence suggests that the effects of this gene may be especially salient in the context of familial risk for child maladjustment. We therefore examined whether the single-nucleotide polymorphism producing a valine-to-methionine substitution at codon 66 (val66met) of the BDNF gene was associated with childhood NE, in the context of parental depression and relationship discord. A sample of 413 three-year-old children was assessed for NE using standardized laboratory measures. The children's parents completed clinical interviews as well as a measure of marital satisfaction. Children with at least one BDNF methionine (met) allele exhibited elevated NE when a parent had a history of depressive disorder or when relationship discord was reported by a parent. In contrast, this allele was associated with especially low NE when parental depression was absent and when the parental relationship was not discordant. Our findings suggest that the BDNF met allele confers increased child sensitivity to both positive and negative familial influences.     

Auditory and visual hallucinations in a sample of severely mentally ill Puerto Rican women: an examination of the cultural context

The content, interpretation, and structure of hallucinations experienced by individuals with severe mental illness are influenced by the culture of the individuals who experience them. We analyzed the content of visual and auditory hallucinations of 53 Puerto Rican women in northeastern Ohio with a diagnosis of a severe mental illness (SMI) who were participating in a study of HIV risk among Hispanic women with SMI. Compared to non-hallucinators, hallucinators had lower global assessment of functioning scores and greater suicidality. Hallucinations reflected three themes: religious themes, command hallucinations, and unidentifiable voices. Hallucinators’ subjective experience of their hallucinations ranged from a sense of security to significant distress. Participants developed a wide range of strategies to deal with threatening hallucinations. Provider response to individuals’ experience appeared to impact the quality of the patient–provider relationship. We recommend the inclusion of religious history in the initial assessment of individuals. This will assist the provider in making an accurate diagnosis, distinguishing between religious beliefs and those that reflect underlying pathology, and in increasing the level of cultural competence of the care provided. Religious and spiritual beliefs that provide a source of hope and strength for the patient can be utilized to expand and enhance the patient's coping strategies.     

Action versus inaction: anticipated affect in the theory of planned behavior

Theory of planned behavior (TPB) variables and anticipated affect were assessed in relation to drinking and avoiding alcohol and in relation to eating and avoiding fast food. It was shown that previously reported residual effects of anticipated affect in the prediction of intentions are obtained only when the TPB variables are assessed with respect to one behavior (action or inaction) and anticipated affect is measured in relation to the alternative behavior. When all variables were assessed with respect to the same behavior, anticipated affect made no independent contribution to the prediction of intentions, nor did anticipated affect retain a residual effect when the TPB constructs in relation to the alternative action were included in the prediction equation.     

Future of Victimized Employees: A Model Based on Long-Run Cascading Effects of Experienced Victimization

ABSTRACT

Victimization has been one of the key research areas in the field of organizational behavior; however, current literature on organizational behavior has not sufficiently discussed the underlying processes that lead to changes in victim's behavior and their life. Proposed framework in this paper discusses long-term effects of victimization in two phases. Phase I elaborates the process through which victimization experiences lead to different emotional responses including anger, fear, and sadness in victimized employees. Phase II discusses the long-run cascading effects of emotions on victim's behavior and health. Overall this study suggests that continuous victimization leads to long-lasting devastating effects on victim's life through development of abusive leadership traits, as well as through destructive effects on their physical and mental health.     

Posttraumatic growth in trauma survivors: Implications for practice

The study of positive sequelae to trauma is increasingly a focus of attention in the trauma research literature. This paper describes the construct of posttraumatic growth, a phenomenon that involves positive changes and benefits gained through coping with traumatic experiences. Variables associated with posttraumatic growth are summarized. Specific interventions for counselling psychology practice are described.
