Written Imaginal Exposure for Hoarding Disorder: A Preliminary Pilot Study.

ABSTRACT: Hoarding disorder (HD) is marked by difficulty discarding possessions. Many refuse treatment or drop out, which may be due to treatment's incorporation of in-home decluttering, which is feared and avoided. Thus, strategies to prepare patients for decluttering/discarding are needed. Imaginal exposure (IE), or imagining one's worst fears about discarding, could be one such strategy. This pilot preliminarily tested a short-duration IE intervention compared with a control intervention. Over 3 days, adults diagnosed with HD (n = 32) were randomly assigned to either write about and imagine their worst fears about discarding (IE condition) or a neutral topic (control writing [CW] condition). The IE condition showed significant improvements in HD symptoms from preintervention to 1-week follow-up, with medium to large effects; however, the CW condition did as well. Comparing change scores between conditions, the IE condition's improvements were not significantly different than the CW condition's. Overall, IE was helpful in improving HD symptoms, but this pilot did not indicate that it was more helpful than CW. This raises important questions about possible demand characteristics, placebo effects, or regression to the mean, and it has implications for the design and methodology of other studies assessing IE's utility.

The influence of interactions with pet dogs on psychological distress.

Many people, including nearly half of American households, own a pet dog. Previous work has found that therapy dog interactions reduce distress, but little work to date has empirically established the mood-enhancing effects of interaction with one's own pet dog. In this study, dog owners (N = 73; 86.3% female, 13.7% male; age 25-77 years) underwent a stress-inducing task followed by random assignment to either (a) interacting with their dog (n = 24), (b) an expectancy control (n = 25; "stress-reducing" coloring books), or (c) a waiting control (n = 24). We compared the effects of each condition on affect and state anxiety. Participants assigned to the dog interaction showed greater increases in positive affect, as well as greater reductions in anxiety compared to both expectancy and waiting controls (ds > 0.72, ps < .018). No significant reductions in negative affect were detected. Second, we found that self-reported experiences with animals, attitudes toward animals, or bondedness with their dog did not differentially predict the condition's impact on the owner's mood. Finally, we coded participants' degree of engagement (e.g., time spent playing) with the dog and found that higher engagement predicted reduced negative affect. Overall, interacting with one's own pet dog reduced owners' distress. Such interactions, which occur commonly in daily life, may have the potential to alleviate distress at a large scale. Precisely how this works and for whom it is especially well suited remain intriguing open questions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The mindful gaze: trait mindful people under an instructed emotion regulation goal selectively attend to positive stimuli.

Trait mindfulness confers emotional benefits and encourages skillful emotion regulation, in part because it helps people more deliberately attend to internal experiences and external surroundings. Such heightened attentional control might help skillfully deploy one's attention towards certain kinds of stimuli, which may in turn help regulate emotions, but this remains unknown. Testing how trait mindful people deploy attention when regulating their emotions could help uncover the specific mechanisms of mindfulness that confer its emotional benefits. The present study aimed to determine whether high trait mindfulness is associated with sustained attention biases to (i.e. longer gaze at) emotional scenes, when all participants are given the emotion regulation goal of staying in a positive mood. To measure this, we used eye tracking to assess selective attention to positive, neutral, and negative photographs. Higher trait mindfulness was associated with both a stronger attention bias for positive (vs. neutral and vs. negative) images, as well as greater success staying in a positive mood during viewing. Surprisingly, this attention bias towards the positive images did not mediate the relationship between mindfulness and maintenance of positive mood. Future work should compare visual attention to other emotion regulation strategies that may maximise positive affect for mindful people.

Augmenting group hoarding disorder treatment with virtual reality discarding: A pilot study in older adults.

Hoarding disorder is common and debilitating, especially in older adults, and novel treatment approaches are needed. Many current treatments emphasize skills related to discarding and decision-making about possessions, which can be practiced in the patient's home. However in many cases, in-home visits are unfeasible, or real-life discarding is too difficult. Virtual reality (VR) offers the ability to create a virtual "home" including 3D scans of the patient's actual possessions that can be moved or discarded. VR discarding is an alternative to in-home visits and an approach that provides a stepping stone to real-life discarding. VR has been successfully utilized to treat many disorders but tested minimally in hoarding disorder. In nine older adults with hoarding disorder, we tested an 8-week VR intervention administered to augment a 16-week Buried in Treasures group treatment. Individualized VR rooms were uniquely modeled after each patient's home. During clinician-administered VR sessions, patients practiced sorting and discarding their virtual possessions. The intervention was feasible to administer. Open-ended participant responses, examined by two independent evaluators, indicated that VR sessions were well-tolerated and that participants found them useful, with nearly all participants noting that VR helped them increase real-life discarding. Self-reported hoarding symptoms decreased from baseline to close, with seven of the nine participants showing reliable improvement in this timeframe and none showing deterioration. Results from this exploratory pilot study suggest that VR is a feasible way to simulate an at-home sorting and discarding experience in a manner that may augment skills acquisition. It remains an open question whether VR discarding practice yields greater improvement than existing treatments. VR for this population merits further clinical investigation.

Seeing red: Distraction influences visual attention for anger but not for other negative emotions.

Emotion regulation is a vital skill that improves psychological well-being and overall functioning. Distraction (the purposeful internal disengagement from an emotional stimulus) and cognitive reappraisal (the process of changing one's thoughts about an emotional event/stimulus) are two well-established regulation strategies that can effectively decrease negative affect. Less understood, however, are the attention allocation strategies that occur when engaging in these emotion regulation strategies-specifically, do people visually scan emotional information differently when distracting vs. reappraising? In the current study, community participants were randomly assigned to either distract, reappraise, or view naturally while watching four emotional film clips that each elicited a different negative emotional state: anger, fear, sadness, and disgust. Eye tracking was used to record total time spent gazing ("dwell time") at faces within the emotion-eliciting film clips. An effect of condition was found for anger-eliciting material only: participants in the distraction condition exhibited shorter dwell times compared with reappraisal and natural viewing. Importantly, this effect was moderated by state anxiety, such that it was found at low but not high levels of state anxiety. These results show that emotion regulation strategies differentially affect attention to emotion-eliciting stimuli and points to the role of current affective states in impacting how distraction is used.

Separating From the Mothership: A Coordinated Individual and Parent-Based Approach to Severe Agoraphobia in a Young Adult.

Families are invested in an older adolescent gradually separating from the family to live independently as an adult, but for many families, adolescent psychopathology makes this transition difficult. Addressing such psychopathology is critical in preventing "failure to launch," a breakdown in gaining age-appropriate independence from parents. This case study illustrates a promising approach directed at helping an 18-year-old female with agoraphobia and panic disorder who, upon intake, was at risk for long-lasting, prohibitive dependence on her parents. The clinical approach entails the convergence of two psychological treatments conducted in the same treatment center. One provider, working directly with the patient, delivered traditional cognitive-behavioral therapy (CBT) for anxiety. A second provider, working with the parents, delivered Supportive Parenting for Anxious Childhood Emotions (SPACE) a parent-based treatment focused on reducing family accommodation of the patient's anxiety. Behavioral indices and self-report scores indicated clinically significant improvement following the combined intervention. Attention is drawn to the convergence of those treatments and the utility and special considerations in taking this kind of approach. Overall, the combined treatment may have been more successful than the sum of its parts at preventing failure to launch. This case study, the first to describe the integration of CBT and SPACE, can provide useful guidance for clinicians helping families of adult children to transition to independence.

Examining subjective sleep quality in adults with hoarding disorder.

Hoarding disorder (HD), characterized by difficulty parting with possessions and functionally impairing clutter, affects 2-6% of the population. Originally considered part of Obsessive-Compulsive Disorder (OCD), HD became a distinct diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. While sleep impacts OCD, little is known about sleep in HD. As HD patients often report poor sleep in clinical settings, understanding global subjective sleep quality and disturbances may lead to novel therapeutic targets. To address this gap, the authors used a sample of convenience: an existing data set designed to screen research study eligibility and explore the psychopathology and phenomenology of OCD and HD. The data set included information collected from individuals with HD (n = 38), OCD (n = 26), and healthy participants (n = 22) about insomnia, sleep quality, and mood using interviews and structured instruments including the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Depression Anxiety Stress Scales (DASS). In this data set, HD and OCD groups reported significantly greater insomnia symptoms and poorer sleep quality compared with healthy controls while controlling for depression, age, and gender. A sizable minority of HD and OCD individuals met criteria for comorbid sleep disorders. OCD and HD groups differed in delayed sleep phase prevalence. To our knowledge, this is the first study examining subjective sleep quality and insomnia in HD as compared to healthy individuals and those with OCD, while controlling for relevant clinical characteristics. Given that there are evidence-based treatments for insomnia and other sleep disorders, our study raises the possibility that treatment interventions targeting sleep may improve HD outcomes.

Does repetitive negative thinking affect attention? Differential effects of worry and rumination on attention to emotional stimuli.

Worry and rumination, two cardinal responses to emotional events, are key for maintaining negative emotion and have been implicated in the etiology and maintenance of anxiety and depressive disorders. Though worry and rumination are highly correlated with one another and people who engage in one often engage in both, they may differentially affect emotion. Specifically, previous work suggests that worry helps people avoid (intense) emotion, while rumination provokes it. Examining the ways in which these two forms of repetitive negative thinking (RNT) influence cognitive processing of emotional material may help us better understand the emotional sequelae of worry and rumination. This study examines visual attention to emotional information, since attending to certain types of information opens the door for further processing of it. The current study induced worry and rumination and then used eye tracking to compare how each form of RNT influenced the allocation of attention to emotional scenes. Participants induced to worry, compared with those induced to ruminate, spent less time viewing positive (vs. neutral) scenes and were the only group to preferentially maintain their attention on negative images when they were paired with positive images. These findings suggest that worry, compared with rumination, leads to the relative avoidance of positive information. Implications of these findings for research on mood and anxiety disorders are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Seeing the world through rose-colored glasses: People who are happy and satisfied with life preferentially attend to positive stimuli.

Given the many benefits conferred by trait happiness and life satisfaction, a primary goal is to determine how these traits relate to underlying cognitive processes. For example, visual attention acts as a gateway to awareness, raising the question of whether happy and satisfied people attend to (and therefore see) the world differently. Previous work suggests that biases in selective attention are associated with both trait negativity and with positive affect states, but to our knowledge, no previous work has explored whether trait-happy individuals attend to the world differently. Here, we employed eye tracking as a continuous measure of sustained overt attention during passive viewing of displays containing positive and neutral photographs to determine whether selective attention to positive scenes is associated with measures of trait happiness and life satisfaction. Both trait measures were significantly correlated with selective attention for positive (vs. neutral) scenes, and this general pattern was robust across several types of positive stimuli (achievement, social, and primary reward), and not because of positive or negative state affect. Such effects were especially prominent during the later phases of sustained viewing. This suggests that people who are happy and satisfied with life may literally see the world in a more positive light, as if through rose-colored glasses. Future work should investigate the causal relationship between such attention biases and one's happiness and life satisfaction.

Positive Emotion Regulation and Psychopathology: A Transdiagnostic Cultural Neuroscience Approach.

There is burgeoning interest in the study of positive emotion regulation and psychopathology. Given the significant public health costs and the tremendous variance in national prevalence rates associated with many disorders of positive emotion, it is critical to reach an understanding of how cultural factors, along with biological factors, mutually influence positive emotion regulation. Progress in this domain has been relatively unexplored, however, underscoring the need for an integrative review and empirical roadmap for investigating the cultural neuroscientific contributions to positive emotion disturbance for both affective and clinical science domains. The present paper thus provides a multidisciplinary, cultural neuroscience approach to better understand positive emotion regulation and psychopathology. We conclude with a future roadmap for researchers aimed at harnessing positive emotion and alleviating the burden of mental illness cross-culturally.
