Personality Traits Predict Irrational Beliefs

Irrational beliefs are the focus of many psychological theories, since research has shown that holding irrational beliefs often leads to unhealthy emotions, dysfunctional behaviors, and psychological disturbances. The aim of such therapies as rational emotive behavioral therapy and cognitive behavioral therapy is to dispute irrational beliefs to promote more rational ways of thinking; however they do not take into account individual personality differences. The aim of this study was to determine whether personality traits predict rational and irrational beliefs in a mixed student and clinical sample. It was hypothesized that the domains of the five factor model of personality would predict rational beliefs as well as a range of irrational beliefs. Our findings supported the hypothesis, showing distinct associations between personality traits and each specific irrational belief. Neuroticism predicted rational beliefs as well as six out of the seven types of irrational beliefs measured. Additionally, extraversion predicted rationality and self-downing, openness predicted need for comfort and total irrationality, and conscientiousness predicted need for achievement and demand for fairness. Agreeableness did not predict any type of rational or irrational beliefs. Knowledge of these distinct relationships may increase a clinician’s ability to conceptualize a therapy case and determine the best approach to treatment.     

Trajectories of Depression and Anxiety Symptoms in Adolescent Girls: A Comparison of Parallel Trajectory Approaches

Longitudinal mixture models have become popular in the literature. However, modest attention has been paid to whether these models provide a better fit to the data than growth models. Here, we compared longitudinal mixture models to growth models in the context of changes in depression and anxiety symptoms in a community sample of girls from age 10 to 17. Model comparisons found that the preferred solution was a 5-class parallel process growth mixture model that differed in the course of depression and anxiety symptoms reflecting both ordering of symptoms and qualitative group differences. Comparisons between classes revealed substantive differences on a number of outcomes using this solution. Findings are discussed in the context of clinical assessment and implementation of growth mixture models.     

Psychological contracts and their implications for commitment: A feature-based approach

Two studies were conducted to examine the link between employee perceptions of the psychological contract and their affective and normative commitments to the organization. The authors adapt a new approach to the study of psychological contracts by developing a generalizable measure of contract features (e.g., scope; time frame). In Study 1 (N = 301), the authors predicted and found that employees’ perceptions of the contract’s features contributed beyond perceptions of contract type (i.e., transactional; relational) and fulfillment to the prediction of affective and normative commitment. In Study 2 (N = 147), the features measure was refined and results from the first study were largely replicated. In both studies, affective and normative commitment were greater when employees viewed the contract as broad, trust-based, equal, negotiated, tangible, and long-term, and weaker when they saw it as unequal, imposed, and short-term. We also found evidence for patterns of features that correspond to transactional and relational contracts, as well as to recently proposed balanced contracts and I-Deals. Implications for theory and the management of psychological contracts are discussed.     

Becoming irreplaceable: How comparisons to the partner’s alternatives differentially affect low and high self-esteem people

It is proposed that people are motivated to feel hard to replace in romantic relationships because feeling irreplaceable fosters trust in a partner’s continued responsiveness. By contrast, feeling replaceable motivates compensatory behavior aimed at strengthening the partner’s commitment to the relationship. A correlational study of dating couples and two experiments examined how satiating/thwarting the goal of feeling irreplaceable differentially affects relationship perception and behavior for low and high self-esteem people. The results revealed that satiating the goal of feeling irreplaceable increases trust for people low in self-esteem. In contrast, thwarting the goal of feeling irreplaceable increases compensatory behaviors meant to prove one’s indispensability for people high in self-esteem.     

Effects of experienced disgust on habituation during repeated exposure to threat-relevant stimuli in blood-injection-injury phobia

Despite growing evidence implicating disgust in the etiology of blood-injection-injury (BII) phobia, the relevance of disgust for exposure-based treatment of BII phobia remains largely unknown. Individuals with BII phobia were randomly assigned to a disgust (view vomit videos) or neutral activation (view waterfall videos) condition. They were then exposed to 14 videotaped blood draws, during which fear and disgust levels were repeatedly assessed. Participants then engaged in a behavioral avoidance test (BAT) consisting of exposure to threat-relevant stimuli. Examination of outcome comparing the identical first and last blood-draw clips revealed that fear and disgust toward blood draws was significantly reduced in both groups. Disgust levels were also found to be more intense for the video stimuli relative to fear levels whereas the opposite was true for BAT stimuli. Contrary to predictions, the disgust induction did not enhance reductions in negative responses to the target video or reduce behavioral avoidance. Growth curve analyses did show that individuals with BII phobia exposed to the disgust induction showed greater initial fear levels during repeated exposure than those in the neutral condition. However, this effect was not consistently observed across different analytic approaches. Changes in fear during exposure were also found to be independent of changes in disgust but not vice versa, and greater initial fear levels during repeated exposure to threat was associated with fear and disgust levels during the BAT. The implications of these findings for conceptualizing the role of disgust in etiology and treatment of BII phobia are discussed.     

Apathy in frontotemporal dementia: behavioral and neuroimaging correlates

We investigated the occurrence of goal-directed motivational change in the form of apathy in patients with frontotemporal dementia (FTD), particularly those with behavioral variant social and executive deficits (bvFTD). Standardized behavioral inventory was employed to survey and compare apathy ratings from patients and caregivers. In cases of bvFTD, apathy ratings were further related to measures of social cognition, executive function, and atrophy on brain MRI. Results indicated that caregivers rated bvFTD patients as having significantly elevated apathy scores though patient self-ratings were normal. Caregiver and self-ratings of FTD samples with progressive nonfluent aphasia and semantic dementia did not differ from healthy controls and their informants. In the bvFTD sample, caregiver apathy scores were not correlated with general cognitive screening or depression scores, but were significantly correlated with social cognition and executive function measures. Voxel-based morphometry revealed that apathy ratings in bvFTD were related to prominent atrophy in the right caudate (including the ventral striatum), the right temporo-parietal junction, right posterior inferior and middle temporal gyri, and left frontal operculum- anterior insula region. Findings suggest that bvFTD is associated with a significant breakdown in goal-directed motivated behavior involving disruption of cortical-basal ganglia circuits that is also related to social and executive function deficits.     

The role of negative affectivity and negative reactivity to emotions in predicting outcomes in the unified protocol for the transdiagnostic treatment of emotional disorders

The present study aimed to understand the contributions of both the trait tendency to experience negative emotions and how one relates to such experience in predicting symptom change during participation in the Unified Protocol (UP), a transdiagnostic treatment for emotional disorders. Data were derived from a randomized controlled trial comparing the UP to a waitlist control/delayed-treatment condition. First, effect sizes of pre- to post-treatment change for frequency of negative emotions and several variables measuring reactivity to emotional experience (emotional awareness and acceptance, fear of emotions, and anxiety sensitivity) were examined. Second, the relative contributions of change in negative emotions and emotional reactivity in predicting symptom (clinician-rated anxiety, depression, and severity of principal diagnosis) reductions were investigated. Results suggested that decreases in the frequency of negative emotions and reactivity to emotions following participation in the UP were both large in magnitude. Further, two emotional reactivity variables (fear of emotions and anxiety sensitivity) remained significantly related to symptom outcomes when controlling for negative emotions, and accounted for significant incremental variance in their prediction. These findings lend support to the notion that psychological health depends less on the frequency of negative emotions and more on how one relates to these emotions when they occur.     

In the beginning: role of autonomy support on the motivation, mental health and intentions of participants entering an exercise referral scheme

Self-determination theory (Deci & Ryan, 2000, Intrinsic motivation and self-determination in human behaviour. New York: Plenum Publishing) highlights the impact autonomy supportive environments can have on exercise motivation and positive health outcomes. Yet little is known about whether differential effects occur as a function of which significant other is providing this support. Further, no research has examined the relationship between motivation and the social environment with participants' mental health and intentions to be physically active before entering an exercise intervention. Study participants were 347 British adults who were about to start an exercise referral scheme. Regression analyses revealed that the effects of autonomy support on mental health and physical activity intentions differed as a function of who provided the support (offspring, partner or physician), with the offspring having the weakest effects. A structural model was supported, indicating that autonomy support and more autonomous regulations led to more positive mental health outcomes and stronger intentions to be physically active. Knowledge of the social environmental and personal motivation of those about to commence an exercise programme can provide important insights for professionals supporting such efforts.     

Predictors of interest in direct-to-consumer genetic testing

Direct-to-consumer (DTC) genetic testing is an increasingly available option among individuals searching for information about their health risk factors and ancestry. This study is one of the first to examine predictors of interest in DTC genetic testing. Participants read one of the three types of information about DTC genetic testing (positive only, negative only or both) and reported perceptions of and intentions to pursue testing. The information which people read, their perceptions of the benefits of testing, their perceptions of the barriers to testing and anticipated regret predicted intentions to undergo testing. Interestingly, people who read both positive and negative information did not differ from people who read only negative information in their intentions to pursue testing. We discuss the implications of these findings for predicting interest in this relatively new type of genetic testing and for designing interventions to encourage (or discourage) testing.
