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.     

Test anxiety,self-evaluative worry,and sleep disturbance in college students

Abstract

The present research examined the extent to which sleep disturbance is involved in the experience of test anxiety. In Study 1, a sample of 80 subjects completed a trait measure of test anxiety and completed a sleep inventory with reference to the past 30 days. In Study 2, a sample of 188 subjects provided measures of trait and state test anxiety and completed a sleep inventory for the night preceding an actual test. The results of Study 1 and Study 2 confirmed that test anxiety is associated with self-reported sleep disturbance. In addition, the results of Study 2 showed that sleep disturbance is also associated with increased state test anxiety. Finally, it was found in Study 2 that sleep disturbance was not related to actual test performance. However, poorer test performance was associated with increased state and trait test anxiety. It is concluded that certain characteristics associated with test anxiety are stable and may be detected in evaluative and non-evaluative situations. The results are discussed with particular reference to their implications for the test anxiety construct itself as well as treatment strategies for the test-anxious student.     

Temporal stability of the implicit association test-anxiety

The Implicit Association Test-Anxiety (IAT-Anxiety; Egloff & Schmukle, 2002) provides an indirect assessment of anxiety by measuring associations of self (vs. other) with anxiety-related (vs. calmness-related) words. In 3 studies (using 3 independent samples), we examined the temporal stability of the IAT-Anxiety. In Study 1, 65 participants responded twice to the IAT-Anxiety with a time lag of 1 week. The test-retest correlation was .58. In Study 2 (N = 39), we extended the time interval between test and retest to 1 month and this yielded a stability coefficient of .62. In Study 3 (N = 36), we examined the long-term stability (time lag: 1 year) of the IAT-Anxiety and this showed a correlation of .47. We discuss implications of these results for the assessment of personality dispositions with the IAT.     

Temporal stability of the transcendent actualization inventory

This paper describes a study of the temporal stability of a new inventory, the Transcendent Actualization Inventory, which aims to estimate actualization of psychospiritual potential. For 200 subjects, the test-retest reliability was .84 for Time 1 vs Time 2. Cronbach coefficient alpha was .81 at Times 1 and 2, as previously reported (N=478).     

Temporal stability of the intrinsic motivation inventory

To examine the temporal stability of the Intrinsic Motivation Inventory a Greek version was administered to 144 undergraduate students after an endurance field test. The same procedure was repeated one week later. Factor analysis followed by varimax rotation showed that three factors (Perceived Competence, Interest/enjoyment, and Effort/importance) explained 65.26% of the total variance. Computed intraclass correlation coefficients (ICC) were .61 for the Perceived Competence subscale, .86 for the Interest/enjoyment, .60 for the Effort/importance, and .70 for the overall scale. The results, however, were modified when the sample was divided in two groups. The first represented small changes in perceived competence between the first and the second measurement, while the second one represented large changes between the two measurements. Recalculated intraclass correlation coefficients for individuals whose Perceived Competence score remained relatively stable yield a high value (.92), whereas individuals whose Perceived Competence changed yield an extremely low value (.60). It was concluded that the Intrinsic Motivation Inventory provides a temporally stable measure, given that perceived competence has not been markedly changed.     

Salient worries of at-risk youth: needs assessment using the things I worry about scale

At-risk students in the southern United States were surveyed using the Things I Worry About Scale. From their responses, 13 categories were ranked from most salient to least salient. The rank order obtained in the present study was compared to that obtained with a normative group of youths in Northern Ireland. The two rank orders were found to be significantly correlated. The relatedness of the rank orderings of the two seemingly disparate samples suggests the universality of the Things I Worry About Scale. The merits of using the scale as part of a comprehensive needs assessment are discussed.     

Stimulus control applications to the treatment of worry

As an internal, self-generated event, worrisome cognitive activity can occur under a wide variety of environmental conditions. The contiguity of the activity and diverse cues would suggest that poor discriminative control is established, and, conversely, that subject-initiated restriction of the temporal and environmental cues for the occurrence of the activity may reduce its frequency during the day. Two experiments are reported wherein self-labeled worriers received either no-treatment or a 4-week trial of stimulus control instructions designed to effect such a restriction. Daily worry reports were found to decline significantly among treated subjects relative to controls.     

Some aspects of sleep disturbance in coronary patients.

Of 42 coronary care patients studied during 10 hr. of polygraphically recorded sleep, 28 were in an open-ward coronary care unit and 14 were in a semi-private telemetry unit. The observed sleep disturbances were not a function of type of unit, length of hospitalization, sex, or medications. Sleep was significantly less fragmented in those patients judged less severe in pathology. These results indicate that alterations in normal sleep patterns occur routinely within coronary care environments, even in the absence of disturbing environmental stimuli and suggest that a closer analysis be made of sleep in these settings in light of the known relationships between sleep and cardiac function.     

Temporal stability of a safety attitude inventory

The purpose of this study was to examine the temporal stability of a paper-and-pencil inventory on safety attitudes, the Employee Safety Inventory. 62 employees of a major publishing company completed the inventory twice with a 10-day interval between testings. A test-retest reliability coefficient of .88 was obtained for the over-all Safety Index. No significant differences in reliability coefficients were found between men and women or between those who had experienced major life events during the time between testings and those who had not experienced such events. This inventory provided a highly reliable measure of safety attitudes.     

Barrier score and the values ascribed to selected individuals by high school students

The Barrier score measure, derived from responses to Rorschach stimuli, was related to the values held by grade 9 high school students. The Barrier score is reflected in a psychological barrier which surrounds the individual and separates him from his environment. High Barrier individuals have a firmer base of psychological operations than their low Barrier counterparts. Groups of high and low Barrier students rated a series of four person stimuli judged to be representative of the outlook of high and low Barrier persons. Ratings were made using a common set of values scales. Multivariate group differences were observed for the stimuli: Sportsman (p = .01), Leader of a Country (p = .03), and Astronomer or Scientist (p = .03), These differences were in terms of derived discriminant functions. Comment is offered on the need for refined techniques for identifying person stimuli compatible with the high Barrier and low Barrier image.     

Temporal stability of self-report measures in agoraphobia research

Forty subjects, meeting DSM-III criteria for agoraphobia completed, on two occasions, a comprehensive assessment battery. Measures encompassed anxiety, phobia, depression and general symptomatology dimensions of functioning, and consisted of instruments widely employed as outcome measures in agoraphobia research. The test-retest time periods were divided into 4-, 10- and 16-week intervals to ascertain their temporal stability, an often ignored parameter of reliability. The results indicate that agoraphobia, anxiety, depression and general symptomatology measures were temporally stable. However, test-retest reliabilities of the scales' subscores were generally inferior to those of the total score. The findings are discussed, with recommendations for more programmatic psychometric research in the assessment of anxiety disorders.     

Evaluating motion detection to score sleep disturbance for children: A translational approach to developing a measurement system

Information obtained via direct observation of children's sleep disturbance throughout the night in their home can guide the assessment and treatment process, but watching live or via recorded video might be impractical in terms of time expenditures. In Experiment 1, we assessed the accuracy and reliability of a motion‐detection camera with human motor movements. In Experiment 2, we tested the system's generality by using it to obtain in‐home measures of sleep disturbance for three children with autism spectrum disorder and compared the accuracy to a continuous measurement system. We also measured scoring efficiency and assessed parents' acceptability of the camera. Results provide preliminary support for motion detection in measuring sleep disturbance, but further evaluation of motion detection to improve accuracy is warranted.     

Temporal stability in the Rorschach method: a meta-analytic review

The temporal stabilities of the Rorschach method scoring systems were investigated. A comprehensive literature search was conducted to find all test-retest studies, both regular and from control samples in therapy evaluation studies. Meta-analyses were conducted for samples, individual entries, and variables in 36 samples. Separate analyses were made for 10 samples using the Comprehensive System (CS; Exner, 1993). The temporal stability was high, especially those obtained from regression model predictions. The CS consistently shows higher stability than other systems, whereas increasing retest intervals leads to decreasing stability. Shortcomings of the available studies are highlighted and discussed, and recommendations are given for design and methodology.
