Worry in imagery and verbal form: effect on residual working memory capacity

Worry-prone individuals have less residual working memory capacity during worry compared to low-worriers (Hayes, Hirsch, & Mathews, 2008). People typically worry in verbal form, and the present study investigated whether verbal worry depletes working memory capacity more than worry in imagery-based form. High and low-worriers performed a working memory task, random interval generation, whilst thinking about a worry in verbal or imagery form. High (but not low) worriers had less available working memory capacity when worrying in verbal compared to imagery-based form. The findings could not be accounted for by general attentional control, amount of negatively-valenced thought, or appraisals participants made about worry topics. The findings indicate that the verbal nature of worry is implicated in the depletion of working memory resources during worry among high-worriers, and point to the potential value of imagery-based techniques in cognitive-behavioural treatments for problematic worry.     

Worry and Sleep Length Revisited: Worry,Sleep Length,and Sleep Disturbance Ascribed to Worry

The author administered university students (N = 222; 152 women, 70 men) the Worry Domains Questionnaire (F. Tallis, G. C. L. Davey, & A. Bond, 1994) and a newly constructed scale (the Sleep Disturbance Ascribed to Worry Scale) to measure sleep disturbance attributed to worry. To revisit previous studies (i.e., E. Hartmann, F. Baekeland, & G. R. Zwilling, 1972; S. J. H. McCann & L. L. Stewin, 1988) that suggested that sleep length was positively related to worry, the author also asked the students a question about habitual sleep length. The results indicated that worry and sleep disturbance attributed to worry were negatively related to sleep length. A regression analysis revealed that worry was significantly negatively related to habitual sleep length irrespective of sleep disturbance ascribed to worry.     

Worry propensity and the perception of risk

This paper examines how the tendency to worry impacts risk estimation for an upcoming, stressful event. Students in a statistics class completed worry, anxiety, and subjective risk questionnaires on the first day of class. State-anxiety and subjective risk questionnaires were again administered immediately before their first examination. Subjects showed significant increases in anxiety and the perceived risk of poor academic performance in the class. Risk domains unrelated to the examination (e.g., physical threats) remained stable across measurement periods. Regression analysis was used to determine the independent contribution of worry propensity in predicting elevations in the perceived risk of poor academic performance. The analysis showed that worry propensity predicted subjective risk bias, even after variance attributable to current mood and trait anxiety had been removed. Results from a second series of regression equations suggested subjective risk biases partially mediated the relationship between worry propensity and current mood. These results are used to argue that the elevations in state anxiety observed when worriers are confronted with a stressful event are largely a function of risk inflation.     

Worry and Pathological Worry in Patients with Psoriasis: Cross Sectional and Longitudinal Analyses of the Penn State Worry Questionnaire (PSWQ) in Four Samples of Patients

The purpose of the present study was to examine the psychometric properties of the Penn state Worry Questionnaire (PSWQ) in patients with psoriasis. A series of cross-sectional and longitudinal studies were undertaken to assess the reliability, stability and validity of the measure. Patients with psoriasis from four samples (consecutive attendees, anxious patients, depressed patients, and 6-month follow-up of consecutive attendees) completed the PSWQ and measures assessing related constructs of anxiety and depression (HADS) and coping (COPE). The clinical severity of patients psoriasis was also assessed by dermatologists using the Psoriasis Area and Severity Index (PASI). Exploratory factor analysis was undertaken and receiver operator characteristic (ROC) analyses were used to examine the clinical utility of the PSWQ cut-off score for normal and pathological worry. Exploratory factor analysis suggested that the PSWQ is essentially unidimensional in patients with psoriasis. Intraclass correlation demonstrated that, over a 6-month period, the reproducibility of the PSWQ total scale was good in patients with anxiety and moderate in patients with depression. ROC analysis suggested that the optimum cutoff differentiating pathological worry was > 60, which is commensurate with findings in adult mental health more generally. The PSWQ cutoff for pathological worry showed a lower specificity for depression than anxiety. The PSWQ is an appropriate measure of pathological worry in patients with psoriasis. The cutoff on the scale for pathological worry demonstrates appropriate conceptual overlap with subordinate distress categories of anxiety and depression.

Worry and emotionality components of test anxiety

The purpose of the present study was to investigate the relationship between trait measures of Worry and Emotionality and test anxiety related variables. Ninety-eight undergraduate students completed the Test Anxiety Inventory (TAI) and the following self-report measures toward the end of the psychology exam: Checklist of Positive and Negative Thought, Checklist of Body Sensations (CBS), and Subjective Units of Discomfort Scale (SUDS). Further, the students' scores on the psychology exam and the students' grade point averages (GPA) served as outcome measures of test anxiety. In general the results supported the discriminant validity of the Worry and Emotionality subscales of the TAI. Worry was found to be correlated with measures of internal dialogue and Emotionality was found to be correlated with the self-reported arousal measures.     

The Developmental Psychopathology of Worry

Although childhood generalized anxiety disorder is generally understudied, worry, the cardinal feature of GAD, appears to be relatively common in youth. Despite its prevalence, there are few conceptual models of the development of clinical worry in children. The current review provides a framework for integrating the developmental psychopathology perspective, models of worry in adults, and data available on worry in children. General risk factors for the development of worry are considered, as well as potential pathways including genetics, temperament, cognitive, emotional and parenting influences, as well as the influence of cognitive development. Based on this review, it appears unlikely that main effects models will be able to explain the development of GAD or clinical worry in children and that a broad, complex model incorporating a number of factors and their interactions will best describe etiological and maintaining factors. With this perspective in mind, a number of suggestions for future work are offered.

Motor imagery: the relation between age and imagery capacity

The imagination of motor actions forms not only a theoretical challenge for cognitive neuroscience but may also be seen as a novel therapeutic tool in neurological rehabilitation, in that it can be used for relearning motor control after damage to the motor system. However, since the majority of rehabilitation patients consist of older individuals it is relevant to know whether the capacity of mental imaging is compromised by age. Scores on the vividness of movement imagery questionnaire were obtained for 333 participants, divided in three age groups. Results showed that elderly participants were slightly worse in motor imagery capacity than younger participants, particularly in relation to motor imagery from an internal (first person) perspective. Furthermore, a possible relation between the level of physical activities and motor imagery capacity is discussed.     

Effects of Rumination and Worry on Sleep

Recent research suggests that the stress-sleep relationship is mediated by pre-sleep arousal (PSA) and that cognitive arousal has a stronger mediating effect than somatic arousal; however, this has not been directly tested. Using multilevel moderated mediation, we compared the effects of cognitive arousal and somatic arousal within the stress-sleep relationship. We also assessed whether two forms of repetitive negative thought—rumination and worry—are similarly involved in the stress-sleep relationship. Data was collected from 178 participants across the United States via an online platform. Participants completed baseline self-report surveys examining rumination tendencies and worry tendencies. Over the course of 2 weeks, participants completed daily questionnaires assessing daily stress, PSA, and sleep quality. Results indicated that indirect effects from stress to sleep quality via PSA were statistically significant at low and high levels of rumination and worry, and people at high levels of rumination and worry had stronger relationships between stress and PSA. Across all models, cognitive arousal consistently accounted for more of the variance in the stress-sleep relationship as compared to somatic arousal. Implications for the cognitive behavioral treatment of insomnia are discussed.     

Development and validation of the Causes of Re-Injury Worry Questionnaire

Re-injury worry is an important construct in competitive sport that may influence performance and increase the risk of re-injury. However, there are currently no available instruments to measure the causes of re-injury worry. The purpose of this study was to develop the Causes of Re-Injury Worry Questionnaire (CR-IWQ). The study was conducted in three independent research phases to investigate the following: (a) the content relevance, (b) the factor structure and the factorial validity, (c) the concurrent validity, (d) the discriminant validity, and (e) the test-retest reliability (intraclass correlation coefficients; ICC), and the internal consistency of the instrument. Exploratory factor analysis (EFA) was chosen to examine the factor structure of the CR-IWQ. Confirmatory factor analysis (CFA) was used to examine further the factorial validity of the instrument. A number of valid constructs were used to assess the concurrent and discriminant validity of the CR-IWQ. The reliability of the new instrument was examined using Pearson r (ICC) and Cronbach α. Three hundred and seventy athletes with an acute musculoskeletal sport injury in the last year participated in the study. EFA revealed a 12-item model, representing two factors ("Re-injury worry due to rehabilitation" and "Re-injury worry due to opponent's ability"). CFA supported the two-factor model of the CR-IWQ. The concurrent and discriminant validity of the CR-IWQ was confirmed by examining correlations between the CR-IWQ with other constructs. The ICCs and the Cronbach α indices of the CR-IWQ were acceptable. We have demonstrated that the CR-IWQ is a good psychometric instrument that can be used for clinical and research purposes.     

A New Worry for the Humean Internalist

The Humean internalist finds Humean motivational theses and reasons internalism to be independently attractive. She therefore combines them, in the hope of creating a theory of reasons that is attractive for all of the reasons that each thesis is attractive. On this score, she succeeds. However, there is a drawback. Those who build a theory of reasons by combining Humean motivational theses and reasons internalism face a dilemma. If you combine these views, either you are committed to a theory of reasons that allows all of a person’s reasons to simultaneously change, erratically and randomly, or you are committed to a theory of reasons that fixes a person’s reasons at birth, in which case they remain stable and unchanging over a lifetime. Neither alternative is attractive. Humean internalism cannot navigate a path between these two extremes, and this should worry the Humean internalist.     

Development and psychometric properties of the Student Worry Questionnaire-30

Described are the development and initial psychometric properties (Ns = 50 and 188) of a self-report measure, the Student Worry Questionnaire-30, for use with college undergraduates. Exploratory principal components analyses (Ns = 388, 350, and 396) with oblimin rotation indicated six domains of worrisome thinking, financial-related concerns, significant others' well-being, social adequacy concerns, academic concerns, and general anxiety symptoms. The total score and scale scores showed internal consistency of .80 to .94. Also, test-retest reliability analyses (.75 to .80) support consistency of responses over 4 wk. Strong evidence for convergent validity) was indicated. Confirmatory factor analysis confirmed the fit of the 6-factor oblique model. Limitations of the present studies, and directions for research are discussed.     

Confirmatory factor analysis of the Penn State Worry Questionnaire

Worry is often assessed with the 16-item Penn State Worry Questionnaire (PSWQ; Meyer, Miller, Metzger, & Borkovec, 1990. Behaviour Research and Therapy, 28, 487-495), but the factor structure of the PSWQ is not well articulated. Three factor analyses of the PSWQ have been conducted, with two (Brown, Antony, & Barlow, 1992. Behaviour Research and Therapy, 30, 33-37; van Rijsoort, Emmelkamp, & Vervaeke, 1999) retaining a unifactorial solution and one (St?ber, 1995) retaining a two-factor solution. We sought to determine the relative strengths of these solutions. Seven hundred eighty-eight undergraduates completed the PSWQ and measures of depression and anxiety. Confirmatory factor analyses indicated that the two-factor solution provided a better fit to the data. There was also evidence for a higher order worry factor. Multiple regression analyses revealed that factor 1 (Worry Engagement) explained the majority of the variance in the symptom measures. The higher order worry factor also accounted for variance in some measures. Compared to the PSWQ total score, Worry Engagement demonstrated slightly higher internal consistency and significantly stronger correlations with most measures of depression and anxiety. Factor 2 (Absence of Worry) demonstrated moderate negative correlations with Worry Engagement and the PSWQ Total Score but only modest correlations with depression and anxiety.     

Worry, anxiety, and preferred length of sleep

Sixty-three female and 43 male undergraduates responded to a "worry" scale, a trait anxiety measure, and a question asking preferred length of sleep to clarify conflicting findings regarding the relationship between worry and anxiety and length of sleep (e.g., Hartmann, 1973; Hicks & Pellegrini, 1977; Kumar & Vaidya, 1984). Worry and length of sleep were positively correlated, supporting Hartmann's contentions. Anxiety was related to sleep in a U-shaped curvilinear fashion. Anxiety and worry were substantially correlated (r = .60) for subjects above the median on worry but were not correlated for subjects below the median. Worry may be the underlying construct in the positive relationship between anxiety and length of sleep for highly anxious persons. Comparison of high worry-low anxiety and low worry-high anxiety groups also suggests that our understanding of the relationships among sleep, anxiety, and worry may benefit from the simultaneous consideration of worry and anxiety factors.     

Auditory imagery and the poor-pitch singer

The vocal imitation of pitch by singing requires one to plan laryngeal movements on the basis of anticipated target pitch events. This process may rely on auditory imagery, which has been shown to activate motor planning areas. As such, we hypothesized that poor-pitch singing, although not typically associated with deficient pitch perception, may be associated with deficient auditory imagery. Participants vocally imitated simple pitch sequences by singing, discriminated pitch pairs on the basis of pitch height, and completed an auditory imagery self-report questionnaire (the Bucknell Auditory Imagery Scale). The percentage of trials participants sung in tune correlated significantly with self-reports of vividness for auditory imagery, although not with the ability to control auditory imagery. Pitch discrimination was not predicted by auditory imagery scores. The results thus support a link between auditory imagery and vocal imitation.     

Mental imagery and the third dimension

What sort of medium underlies imagery for three-dimensional scenes? In the present investigation, the time subjects took to scan between objects in a mental image was used to infer the sorts of geometric information that images preserve. Subjects studied an open box in which five objects were suspended, and learned to imagine this display with their eyes closed. In the first experiment, subjects scanned by tracking an imaginary point moving in a straight line between the imagined objects. Scanning times increased linearly with increasing distance between objects in three dimensions. Therefore metric 3-D information must be preserved in images, and images cannot simply be 2-D "snapshots." In a second experiment, subjects scanned across the image by "sighting" objects through an imaginary rifle sight. Here scanning times were found to increase linearly with the two-dimensional separations between objects as they appeared from the original viewing angle. Therefore metric 2-D distance information in the original perspective view must be preserved in images, and images cannot simply be 3-D "scale-models" that are assessed from any and all directions at once. In a third experiment, subjects mentally rotated the display 90 degrees and scanned between objects as they appeared in this new perspective view by tracking an imaginary rifle signt, as before. Scanning times increased linearly with the two-dimensional separations between objects as they would appear from the new relative viewing perspective. Therefore images can display metric 2-D distance information in a perspective view never actually experiences, so mental images cannot simply be "snapshot plus scale model" pairs. These results can be explained by a model in which the three-dimensional structure of objects is encoded in long-term memory in 3-D object-centered coordinate systems. When these objects are imagined, this information is then mapped onto a single 2-D "surface display" in which the perspective properties specific to a given viewing angle can be depicted. In a set of perceptual control experiments, subjects scanned a visible display by (a) simply moving their eyes from one object to another, (b) sweeping an imaginary rifle sight over the display, or (c) tracking an imaginary point moving from one object to another. Eye-movement times varied linearly with 2-D interobject distance, as did time to scan with an imaginary rifle sight; time to tract a point varied independently with the 3-D and 2-D interobject distances. These results are compared with the analogous image scanning results to argue that imagery and perception share some representational structures but that mental image scanning is a process distinct from eye movements or eye-movement commands.     

Fear imagery and the startle-probe reflex

Blink reflexes to acoustic probes, heart rate, and subjective reports were studied during affective memory imagery. Thirty-six undergraduates memorized 6 pairs of neutral and fearful sentences. After learning each pair, they relaxed and listened to a series of uniform tones, one every 6 s. A change in tone pitch (higher or lower) cued recall of one of the two sentences. At the first cue tone, groups (n = 12) were under different instructions: (a) ignore the sentence and relax, (b) silently articulate the sentence, and (c) imagine the sentence content as a personal experience. At the second cue tone, all subjects performed the imagery task. Startle probes (50-ms, 95-dB white noise) were presented unpredictably during relaxation and recall trials. Probe blink reflexes were larger and cardiac rate faster at fear sentence recall than at neutral sentence recall or relaxation. For probe reflexes, this effect was greater for imagery than for nonsemantic recall tasks.
