Impulsivity and Intrusive Thoughts: Related Manifestations of Self-Control Difficulties?

Impulsivity, emotional disorders and cognitive distortions in the general population: highlighting general interaction profiles

Cognitive distortions, defined as erroneous information-processing, are involved in the emergence and maintenance of various mental and emotional disorders, including anxiety and depression. On the other hand, several studies highlight the existence of links between these states and the dimensions of impulsivity. We therefore studied the links between cognitive distortions, anxiety and depressive symptomatology, and impulsivity. Two hundred and forty adults (aged 18-60 years, 101 men, 139 women) completed the French version of the Impulsive Behavior Scale, the Cognitive Distortions Scale for Adults and the Hospital Anxiety and Depression Scale. The results obtained highlight the existence of a cognitive distortion specific profile regarding the urgency dimension. Negative maximization, disqualification of the positive, negative-focused dichotomous reasoning, positive arbitrary focus, and neutral omission in favour of the negative are thus the distortions most associated with the level of urgency of subjects. The results also show, a moderating effect of the level of urgency on the interaction between anxiety and negative focused dichotomous reasoning. As well as on the interaction between depression and positive minimization, and between depression and positive maximization. The discussion of the results focuses on the interpretation of the data regarding the anxiety-depressive states in general population.

The Relationship Between Negative Urgency and Anxiety and Worry in American College Students

The primary objective was to assess the degree to which intolerance of uncertainty accounts for the association between negative urgency and anxiety and worry. The sample included 389 American college students from a state college in the Northeastern United States. Hayes' PROCESS v4.1 (2022) macro was used to investigate the mediating effects of intolerance of uncertainty on the relationship between negative urgency and worry and anxiety. A direct effect of negative urgency on worry was found and a mediating effect of intolerance of uncertainty was observed. A direct effect of negative urgency on state anxiety was found, and a mediating effect of intolerance of uncertainty was observed. The study advances support for the mediatory role of intolerance of uncertainty between negative urgency and anxiety and worry in American college students.

Relationships between adolescent smartphone usage patterns, achievement goals, and academic achievement

As smartphones are emerging as a common device for adolescent, prior studies have provided theoretical and empirical evidence for the factors affecting adolescent smartphone use. However, mainstream research has tended to focus on the negative effects of smartphone. Even though smartphone use can have adverse outcomes, it may also allow students to engage in flexible mobile learning, gain access to important information about their possible future careers and achieve their personal goals. To fill this gap in adolescent smartphone usage, this study explored the smartphone usage patterns of adolescent subpopulations and the associations with their self-control, achievement goals, and academic achievements. Data were collected from 2341 s-year high school students as part of a larger longitudinal panel study. Three distinct smartphone usage profiles were identified in the latent profile analysis: learning, recreational use, and minimal use. Respondents with high perseverance were assigned to the learning group, and respondents with lower compliance and perseverance were assigned to the recreational group. The achievement goal score was found to be the highest in the learning group and lowest in the recreational group. Academic achievement was found to be higher in both the learning and minimal use groups than the recreational use group. Based on these findings, the implications of this study for research and practice are discussed.

Effects of Impulsivity on Competitive Anxiety in Female Athletes: The Mediating Role of Mindfulness Trait

It has been demonstrated that athletes in competitive sports suffer from high levels of competitive anxiety, especially in the case of females. In this sense, it is necessary to identify possible risk and protective factors of those athletes in this collective who suffer from this type of anxiety. However, few studies analyze the relationship between Physical Activity (PA) and anxiety, identifying the possible mediation effect of trait variables such as impulsivity and mindfulness in female athletes. Hence, the aims of this study were: to determine differences between PA levels with anxiety, mindfulness, and impulsiveness; to identify the predictive value of sociodemographic factors and physical activity, impulsivity, and mindfulness on anxiety factors; and to analyze the possible mediating effects of mindfulness on the relationship between impulsivity and anxiety. A total of 242 female athletes underwent an assessment of physical activity, anxiety, mindfulness traits, and impulsivity using validated questionnaires. Data were analyzed according to (1) individual or collective sport, and (2) PA levels according to energy expended (METs min/day). Participants were grouped by light, moderate, and vigorous PA levels. There were 30.5% elite athletes and 73.2% collective sports athletes. Mean age was 22.1 years and mean light, moderate, and vigorous PA were 86.1 ± 136.2, 114.4 ± 159.8, and 370.1 ± 336.3 METs min/day, respectively. Those athletes performing vigorous PA exhibited lower levels of impulsiveness and higher mindfulness traits. As expected, the mindfulness trait was a mediating factor in the relationship between impulsiveness and each factor of competitive anxiety (cognitive, somatic, and self-efficacy). Female athletes could suffer competitive anxiety, especially those who present higher levels of impulsivity. However, higher levels of mindfulness traits seem to be a protective factor in the effects of impulsivity on anxiety in this population and have demonstrated to be significant mediators in this association. Further studies are needed with other female athletes to replicate these results and to determine the specific protective mechanisms of mindfulness traits in preventing competitive anxiety.

Dynamic targeting enables domain-general inhibitory control over action and thought by the prefrontal cortex

Over the last two decades, inhibitory control has featured prominently in accounts of how humans and other organisms regulate their behaviour and thought. Previous work on how the brain stops actions and thoughts, however, has emphasised distinct prefrontal regions supporting these functions, suggesting domain-specific mechanisms. Here we show that stopping actions and thoughts recruits common regions in the right dorsolateral and ventrolateral prefrontal cortex to suppress diverse content, via dynamic targeting. Within each region, classifiers trained to distinguish action-stopping from action-execution also identify when people are suppressing their thoughts (and vice versa). Effective connectivity analysis reveals that both prefrontal regions contribute to action and thought stopping by targeting the motor cortex or the hippocampus, depending on the goal, to suppress their task-specific activity. These findings support the existence of a domain-general system that underlies inhibitory control and establish Dynamic Targeting as a mechanism enabling this ability.

Social anxiety and rumination in the context of the revised reinforcement sensitivity theory and the mediation model of social anxiety

The aim of this study was to examine the relationship between temperament, ruminative thought style and social anxiety using latent variable modeling. Before examining the integrated model that specifies the relations between the constructs, relevant measurement issues were examined. The study was conducted on a heterogeneous sample from the general population that included 1,029 participants (62.1% female) aged 19 to 79. The findings show that the Behavioural Inhibition System is the most important vulnerability factor for the development of social anxiety, and it has both a direct effect and an indirect one through the ruminative thought style. Also, Freeze has an additional contribution to the increased experience of social anxiety. The Behavioural Approach System has complex effects on social anxiety ? with a direct protective effect, and indirectly ? with a facilitation of the ruminative thought style. Thus, BAS can also act as a risk factor. The findings support the revised Reinforcement Sensitivity Theory and provide a basis for the extension of the Kimbrel?s Mediation Model of Social Anxiety.

Cognitive processes in autism: Repetitive thinking in autistic versus non-autistic adults

LAY ABSTRACT

A core feature of autism is the tendency to do the same activity or behaviour repetitively. We wanted to find out if autistic people also experience repetitive thinking, for example, having the same thoughts repeatedly. We thought that there would be a link between repetitive behaviour and repetitive thinking. We asked 54 autistic people and 66 non-autistic people to complete questionnaires measuring repetitive behaviours and obsessive thinking. Next, participants were trained by a researcher to record their thoughts using a structured paper form. They then completed 5 days of thought recording, which they did each time a random alarm sounded on their mobile phone. We found that autistic people had more repetitive thoughts than non-autistic people, but they did not report having more negative or visual thoughts compared with non-autistic people. Autistic people who had more repetitive thoughts during the 5 days of thought recording did not report more repetitive behaviour. However, autistic people who reported more obsessive thinking, for example, more negative and unwanted thoughts, also reported higher levels of repetitive behaviour. We conclude that some repetitive behaviours may be linked to anxiety and that more research is needed to better understand repetitive behaviours in autism.

A multi-method examination of the link between obsessive-compulsive symptomatology and emotion-related impulsivity

OBJECTIVES

Obsessive-compulsive disorder (OCD) is a condition marked by recurrent and distressing thoughts, images, and urges accompanied by repetitive physical or mental rituals. An emerging line of work suggests that emotion may be an important consideration when looking at the role of impulsivity across the spectrum of psychopathology, including OCD. The current study examined the relationship between obsessive-compulsive symptomatology (OCS) and impulsive cognitive and behavioural reactions to emotion using a multi-study, multi-method approach.

DESIGN

Data were collected cross-sectionally online (Study 1) or via an in-person laboratory visit (Study 2).

METHODS

In Study 1, self-report measures of impulsivity and OCS were administered to a large, non-selected community sample (N = 386). Study 2 extended these findings with a young adult sample (N = 107) with clinically elevated OCS using self-report measures, clinical interview, and two behavioural symptom provocation tasks.

RESULTS

Emotion-related impulsivity, but not non-emotion-related impulsivity, was associated with greater severity of OCS across symptom domains and across all modes of assessment. Impulsive cognitive responses to emotion were associated with greater obsession severity, while impulsive behavioural reactions to emotion were associated with greater compulsions. Emotion-related impulsivity also acted synergistically with a belief in the importance and control of thoughts, such that this established risk factor for OCD was associated with greater OCS severity only when behavioural reactivity to emotion was also present.

CONCLUSIONS

Results highlight the importance of considering emotional context when studying impulsivity in OCD, and point to the potentially differential relationship between OCS and behavioural versus cognitive impulsive reactions to emotion.

PRACTITIONER POINTS

Emotion-related impulsivity (ERI) reflects a tendency to act impulsively in the context of strong emotions. ERI was associated with greater OCS across symptom domains and type of symptom assessment (self-report, interview, or symptom provocation). ERI also interacted with an established OCS risk factor, a belief in the importance and control of thoughts, to predict symptom severity, suggesting that it may be important to evaluate and address ERI alongside unhelpful beliefs in patients with OCS. Given the present study's cross-sectional nature, we cannot draw conclusions about the directionality of the ERI - OCS relationship, and while our study included individuals with clinically elevated OCS, results should be replicated in a fully clinical sample.

A Preliminary Exploration of Behaviours Associated with Negative Urgency in Individuals High and Low in Chronic Worry

While chronic worry is typically associated with cautious and harm-avoidant behaviours, there is evidence that people high in chronic worry are characterised by negative urgency (NU), that is, the propensity to act rashly when experiencing negative affect. The present study was a preliminary examination of how rash action and impulsive decision-making manifest for chronic worriers compared to individuals low in worry. In total, 93 participants who endorsed high and low worry and NU responded to open-ended questions about their experience of NU on Amazon Mechanical Turk. Themes were identified using a data-driven approach. Participants high in chronic worry endorsed significantly greater NU compared to those low in worry. However, the types of NU behaviours were similar across participants, with a majority of responses involving initiating interpersonal conflict. Other themes included spending money, excessive eating, alcohol use, and aggressive behaviours. The manifestations of NU were largely consistent with those described in the model of NU. Although individuals higher in chronic worry engaged in NU behaviours to a greater extent, the types of behaviours were similar to those reported by people lower in worry. More research is needed to understand the characteristics of NU-motivated behaviour in individuals high in chronic worry.

Drawing alcohol craving process: A systematic review of its association with thought suppression, inhibition and impulsivity

Alcohol Use Disorder (AUD) is a worldwide public health problem. In recent years, there has been growing evidence supporting craving, the irrepressible desire to drink, as a major mechanism implicated in AUD. Impulsivity is identified as playing a significant role in craving in many studies. However, relationships with inhibition and thought suppression remain unclear in the existing literature. A systematic review was conducted to evaluate their associations in order to better understand the cognitive processes involved in craving.

Studies were identified by searching PubMed, PsycINFO and Web of Science using PRISMA procedure and PICOTS framework. There were included if they assessed craving and thought suppression or inhibition or impulsivity, and sample was composed of AUD participants.

Thirteen studies were included and were categorized in accordance with the evaluated cognitive process. The first part dealt with thought suppression and the second with impulsivity and inhibition. Four studies showed a positive association between thought suppression and increased craving. Two studies showed that poorer inhibition was associated with increased craving and four studies showed that impulsivity was positively associated with craving. Three studies showed a negative association between impulsivity and inhibition and higher craving.

Our review highlights the association of alcohol craving with poorer inhibition and greater impulsivity. Further investigations are needed to give support to different theories and lead to propose an integrative model involving the cognitive process of inhibition in alcohol craving.

It’s the thought that counts: Trait self-control is positively associated with well-being and coping via thought control ability

In the present study, we reason that the ability to keep unwanted thoughts and intrusions at bay – thought control ability – might explain part of the relationship between trait self-control and positive psychological outcomes. We predict that the ability to keep unwanted thoughts at bay causes people high in trait self-control to report higher subjective well-being (Study 1), and makes them to be more likely to cope with stressful life events in an adaptive rather than maladaptive manner (Study 2). Two cross-sectional studies among healthy individuals were conducted (Study 1 n = 284; 70% female; Mage = 22.15 years; Study 2 n = 210, 65.7% female, Mage = 28.07) in which trait self-control, thought control ability, subjective well-being (study 1), and coping styles (study 2) were measured. Additionally, we investigated the mediating role of thought control ability and the conditional effect of gender on this mediation. The results of Study 1 indicate that trait self-control is positively related to subjective well-being. Moreover, thought control ability fully mediated the relationship between trait self-control and subjective well-being, and this effect was particularly strong for women. In Study 2, trait self-control was positively associated with adaptive forms of coping, but negatively with maladaptive coping. Moreover, thought control ability partially mediated the relationship between trait self-control and both types of coping, with stronger results for women than for men. These results suggest that trait self-control affects positive life outcomes in part through an ability to keep unwanted thoughts at bay, thereby facilitating a focus on goal pursuit.

Controlling Unpleasant Thoughts: Adjustments of Cognitive Control Based on Previous-Trial Load in a Working Memory Task

Dynamic cognitive control adjustments are important for integrating thoughts and actions that take place during dynamic changes of environmental demands and support goal-directed behavior. We investigated, in a working memory (WM) paradigm, whether dynamic adjustments in cognitive control based on previous trial load influence the neural response to neutral or unpleasant distracters. We also investigated whether individual self-reported abilities in controlling thoughts influence this effect. Participants performed a WM change detection task with low or high WM-related cognitive demands. An unpleasant or a neutral distractive image was presented at the beginning of each trial, prior to the WM task. We tested for control adjustments that were associated with the load level of the preceding trial task (N-1) on the neural response to the subsequent distractive image. We found an effect of the prior WM task load on a parieto-occipital waveform event-related potential (ERP) that appeared between 200 and 300 ms after the neutral distracter onset. This effect was not observed for the unpleasant distracter. Individual ability for controlling thoughts may influence the effect of cognitive control adjustments on distracter processing during the unpleasant condition. These findings provide evidence that: (1) dynamic cognitive control adjustments are impaired by unpleasant distracters; and (2) the ability to control unpleasant thoughts is linked to individual differences in flexible cognitive control adjustments and shielding of WM representations from unpleasant distracters.

Fifteen Years Controlling Unwanted Thoughts: A Systematic Review of the Thought Control Ability Questionnaire (TCAQ)

Thought control ability is a vulnerability factor implicated in the etiology and maintenance of emotional disorders. This manuscript aims to systematically review the use and psychometric performance of the Thought Control Ability Questionnaire (TCAQ), designed to assess people's ability to control unwanted thoughts. Three electronic databases were searched for papers administering the TCAQ published in indexed peer-reviewed journals. Data (participants characteristics, country, study design, etc.) were extracted from the results for qualitative synthesis. The TCAQ's content validity, dimensionality, internal consistency, test-retest reliability, convergent/divergent validity, floor/ceiling effects, and interpretability were summarized. Two reviewers independently screened articles and assessed quality taking COSMIN criteria into account. Finally, the review included 17 papers. The TCAQ has been administered to healthy individuals, students, and adult patients, in six languages from nine countries. We found that the TCAQ, and its shorter versions, demonstrate robust reliability and adequate content validity. Of interest is the TCAQ's capacity to predict performance in diverse experimental tasks focused on thought control. The TCAQ unidimensionality has been supported in exploratory and confirmatory factor analyses. Regarding construct validity, the TCAQ is significantly related to a wide range of psychopathological measures of anxiety, worry, depression, obsessive-compulsive symptoms, etc. However, as only a few of the included studies had a longitudinal design, we are unable to draw firm conclusions about the measure's temporal stability. Moreover, psychometric aspects such as factorial invariance across different samples have not been analyzed. Despite these limitations, based on available psychometric evidence we can recommend using the TCAQ for measuring perceived control of unwanted thoughts.

The Mediating Role of Emotion Regulation Difficulties in the Relationship Between Self-Compassion and OCD Severity in a Non-Referred Sample

Self-compassion involves extending kindness and understanding to one's self. Research has demonstrated inverse relationships between self-compassion and maladaptive constructs associated with obsessive–compulsive disorder (OCD), including emotion regulation (ER) difficulties. The current study sought to explore associations between self-compassion, ER difficulties, and OCD severity. Data were collected at the International Obsessive–Compulsive Disorder Foundation convention from 62 attendees who reported having a diagnosis of OCD (51% male, mean age 35.9 years). Findings demonstrated that self-compassion and ER difficulties were associated with overall OCD severity. Results also indicated that ER difficulties mediated relationships between self-compassion and overall OCD severity, as well as the severity of two OCD symptom dimensions, responsibility for harm and unacceptable thoughts. These findings suggest that self-compassion and ER difficulties may be involved in the maintenance and severity of OCD.

Case conceptualization from a process-based and modular perspective: Rationale and application to mood and anxiety disorders

This article presents the theoretical, clinical, and practical arguments supporting a process-based transdiagnostic approach to psychotherapy. A working definition of "psychological process" is provided, as well as a tri-dimensional categorization of psychological processes potentially involved in psychopathology. Guidelines are proposed to select psychological interventions based on the active psychopathological processes evidenced in a given case. We also provide a rationale to organize treatment as a set of modules, each addressing a specific psychopathological process. Next, we review the main processes that may be active in mood and anxiety disorders, and that are accessible to clinicians in regular practice. For each process, we propose a validated assessment questionnaire. Finally, we offer a free-access web-based instrument that allows clients to fill in these questionnaires via an internet survey, and that provides therapists with a tool to easily decode and interpret the questionnaire results and to present them to the clients.

Disentangling the role of users' preferences and impulsivity traits in problematic Facebook use

The use of social network sites (SNSs) has grown dramatically. Numerous studies have shown that SNS users may suffer from excessive use, associated with addictive-like symptoms. With a focus on the popular SNS Facebook (FB), our aims in the current study were twofold: First, to explore the heterogeneity of FB usage and determine which kind of FB activity predicts problematic usage; second, to test whether specific impulsivity facets predict problematic use of FB. To this end, a sample of FB users (N = 676) completed an online survey assessing usage preferences (e.g., types of activities performed), symptoms of problematic FB use and impulsivity traits. Results indicated that specific usage preferences (updating one’s status, gaming via FB, and using notifications) and impulsive traits (positive and negative urgency, lack of perseverance) are associated to problematic FB use. This study underscores that labels such as FB “addiction” are misleading and that focusing on the actual activities performed on SNSs is crucial when considering dysfunctional usage. Furthermore, this study clarified the role of impulsivity in problematic FB use by building on a theoretically driven model of impulsivity that assumes its multidimensional nature. The current findings have identifiable theoretical and public health implications.

Childhood ADHD and Negative Self-Statements: Important Differences Associated With Subtype and Anxiety Symptoms

The current study examined the role negative self-statements have on the comorbidity between anxious symptomatology and ADHD-combined presentation (ADHD-C) and ADHD-predominantly inattentive (ADHD-I). A total of 114 children and adolescents with ADHD (M age = 10.15; SD = 2.30; range = 7-16) from a clinic-referred sample were grouped based on a semistructured diagnostic interview and consensus approach (ADHD-C, n = 62; ADHD-I, n = 52). Negative self-statements were measured using the Children's Automatic Thoughts Scale and the total score from the Multidimensional Anxiety Scale for Children was used to measure anxious symptomatology. Findings indicated youth diagnosed with ADHD-C, compared to those diagnosed with ADHD-I, had more frequent personal failure (Cohen's d =.40) and hostile intent negative self-statements (Cohen's d =.47). The association of ADHD subtype and negative self-statements was moderated by anxiety; negative self-statements of personal failure were highest in anxious ADHD-C children (β =.31). A second sample of 137 children and adolescents (M age = 10.61; SD = 2.26; range = 7-16) from a larger clinic-referred sample was utilized to replicate our results dimensionally. Results indicated that both hyperactivity/impulsivity (β = .23, p < .01) and the interaction of hyperactivity/impulsivity and anxiety (β = .17, p < .05) were significant predictors of negative self-statements regarding personal failure, while holding child age, child gender, oppositional symptoms, and inattention constant. In all, negative self-statements should be considered in the treatment and assessment of ADHD with particular attention paid to ADHD subtype and internalizing comorbidity.

Procrastination as a Self-Regulation Failure: The Role of Impulsivity and Intrusive Thoughts

Procrastination has been described as the quintessence of self-regulatory failure. This study examines the relationships between this self-regulatory failure and other manifestations of self-regulation problems, namely impulsivity and intrusive thoughts. One hundred and forty-one participants completed questionnaires assessing procrastination, impulsivity (in particular, the urgency and lack of perseverance dimensions), and intrusive thoughts (i.e., rumination and daydreaming). Main results show that urgency mediated the association between rumination and procrastination, whereas rumination did not mediate the relation between urgency and procrastination. Lack of perseverance mediated the association between daydreaming and procrastination, and daydreaming mediated the relation between lack of perseverance and procrastination. This study highlights the role of impulsivity and intrusive thoughts in procrastination, specifies the links between these self-regulation problems, and provides insights into their (potential) underlying mechanisms. It also opens interesting prospects for management strategies for implementing targeted psychological interventions to reduce impulsive manifestations and/or thought control difficulties accompanying procrastination.

Intolerance of uncertainty in opioid dependency - Relationship with trait anxiety and impulsivity

Intolerance of uncertainty (IU) is the tendency to interpret ambiguous situations as threatening and having negative consequences, resulting in feelings of distress and anxiety. IU has been linked to a number of anxiety disorders, and anxiety felt in the face of uncertainty may result in maladaptive behaviors such as impulsive decision making. Although there is strong evidence that anxiety and impulsivity are risk factors for addiction, there is a paucity of research examining the role of IU in this disorder. The rate of opioid addiction, in particular, has been rising steadily in recent years, which necessitates deeper understanding of risk factors in order to develop effective prevention and treatment methods. The current study tested for the first time whether opioid-dependent adults are less tolerant of uncertainty compared to a healthy comparison group. Opioid dependent patients undergoing methadone maintenance therapy (n = 114) and healthy comparisons (n = 69) completed the following scales: Intolerance of Uncertainty Scale, the Barrett Impulsivity Scale, and the State Trait Anxiety Inventory. Analysis revealed that these measures were positively correlated with each other and that opioid-dependent patients had significantly higher IU scores. Regression analysis revealed that anxiety mediated the relationship between IU and impulsivity. Hierarchical moderation regression found an interaction between addiction status and impulsivity on IU scores in that the relationship between these variables was only observed in the patient group. Findings suggest that IU is a feature of addiction but does not necessarily play a unique role. Further research is needed to explore the complex relationship between traits and how they may contribute to the development and maintenance of addiction.

Shared and Distinct Cognitive/Affective Mechanisms in Intrusive Cognition: An Examination of Worry and Obsessions

Generalized anxiety disorder and obsessive-compulsive disorder are defined by chronic intrusive thoughts. The aim of the present study was to evaluate the relationship between cognitive (attentional control) and motivational (negative urgency) mechanisms potentially underlying worry and obsessions. Participants (N = 526) completed an online questionnaire battery consisting of self-report measures of worry, OCD symptoms, attentional control (AC), negative urgency (NU), and trait negative affect. After controlling for trait negative affect, self-reported AC was negatively related to worry, repugnant obsessions, and ordering symptoms. Greater NU was associated with increased worry and repugnant obsessions. Further, self-reported AC and NU interacted such that greater NU was associated with greater worry at high but not low levels of AC. AC and NU were independently associated with repugnant obsessions. Perceived executive functioning impairments may confer risk for intrusive thoughts, particularly worries, whereas distress-driven impulsivity may contribute to the involuntary, ego-dystonic features of intrusions.

Exploring the relationship between worry and impulsivity in military recruits: the role of mindfulness and self-compassion as potential mediators

When military recruits cannot tolerate the stressful environment in the military, they typically become more impulsive. Impulsivity serves to avoid the stress, or, in other words, to release the pressure and cope. Becoming more impulsive, however, is related to damaging behaviours and unsuccessful coping. This research explored the relationship between worry and impulsivity in armed forces, and the possibility of mindfulness and self-compassion mediating this relationship. Participants (n = 166), who were in the second week of their basic military training, completed questionnaires in mindfulness, self-compassion, worry and impulsivity. Results indicated that worry related positively to impulsivity. Further, the negative relationship of worry with mindfulness and self-compassion mediated the relationship between worry and impulsivity. Findings support the notion that lacking mindfulness and self-compassion, in excessive worriers, may lead to impulsivity. This research concluded that mindfulness and self-compassion may assist military personnel who are exposed to highly stressful environments. Alternative explanations and future directions are discussed.

Higher psychoticism as a predictor of thoughts of harming one's infant in postpartum women: a prospective study

BACKGROUND

Some women experience thoughts of harming their infants during the early postpartum period. These intrusive thoughts are conceptually similar to obsessive-compulsive disorder. The aim of our study was to assess whether personality characteristics may predict a mother's development of postpartum thoughts of harming her infant.

METHODS

We studied 137 women with no psychiatric history. They were assessed at two different times during the postpartum period (2-3days after giving birth and during the 8th week following delivery). We assessed postpartum thoughts of harming one's infant with a semi-structured interview conducted in person. Personality characteristics were assessed with the Eysenck Personality Questionnaire. Depression was assessed with the Edinburgh Postnatal Depression Scale and with a structured interview (Diagnostic Interview for Genetic Studies). We also assessed socio-demographic variables, obstetric variables and stressful life events. Adjusting for age, depression and stressful life events, logistic regression was conducted to explore the relationship between a woman's personality characteristics and postpartum thoughts of harming her infant.

RESULTS

Women with postpartum thoughts of harming their infants scored higher in EPQ-Psychoticism (P=0.003) but not in neuroticism or extraversion. EPQ-Psychoticism was significantly associated with the presence of postpartum intrusive thoughts (OR=1.67, p=0.003) after adjusting for other personality dimensions, age, depression and life stress. Those women scoring 5 or higher in EPQ-Psychoticism were 5.5 times more likely to report postpartum intrusive thoughts (p=0.004).

CONCLUSIONS

In healthy women without psychiatric history, psychoticism is a predictor of postpartum thoughts of harming their infants.

Linking impulsivity and inhibitory control using manual and oculomotor response inhibition tasks

Separate cognitive processes govern the inhibitory control of manual and oculomotor movements. Despite this fundamental distinction, little is known about how these inhibitory control processes relate to more complex domains of behavioral functioning. This study sought to determine how these inhibitory control mechanisms relate to broadly defined domains of impulsive behavior. Thirty adults with attention-deficit/hyperactivity disorder (ADHD) and 28 comparison adults performed behavioral measures of inhibitory control and completed impulsivity inventories. Results suggest that oculomotor inhibitory control, but not manual inhibitory control, is related to specific domains of self-reported impulsivity. This finding was limited to the ADHD group; no significant relations between inhibitory control and impulsivity were found in comparison adults. These results highlight the heterogeneity of inhibitory control processes and their differential relations to different facets of impulsivity.

Distress tolerance and obsessions: an integrative analysis

BACKGROUND

Recent research implicates a potential relationship between poor distress tolerance (DT) and obsessive-compulsive disorder (OCD) and obsessions in particular, though this evidence has been largely indirect. We sought to examine the incremental and specific associations between DT and obsessions using multiple methodologies.

METHODS

We conducted three separate studies using independent nonclinical samples (total N=558) that involved cross-sectional (Study 1) and prospective self-report designs (Study 2), as well as the use of an in vivo neutralization task (Study 3).

RESULTS

Poor DT was specifically associated with obsessing but not other OCD symptoms, even when covarying for several theoretically relevant constructs. Further, poor DT was predictive of residual change in obsessing symptoms 1-month later. Poor DT was also associated with neutralization in response to an OCD-like intrusion and postneutralization period anxiety.

CONCLUSIONS

These consistent findings provide support for an important relationship between DT and obsessions and suggest that interventions targeting DT may have special benefit for the treatment of obsessions.
