    Notes: Twelve undergraduate volunteers received 12 sessions of heart rate biofeedback training involving one of two experimental conditions. One-half of the subjects received 4 sessions of high sensitivity analogue heart rate biofeedback, followed by 4 sessions of low sensitivity feedback, and then, 4 final sessions of high sensitivity feedback. The other half of the subjects received the exact opposite order of feedback conditions. All subjects were instructed to accelerate heart rate during 8 trials in each session. The results were contrary to the hypothesis derived from a motor skills model of visceral learning, i.e., the low feedback sensitivity condition consistently produced larger magnitude heart rate acceleration in comparison to the high sensitivity condition. These findings were discussed in terms of methodological suggestions for future research and in terms of the motor skills model of visceral learning.

    Notes: Frontal EMG was concurrently measured using two different electrode placements for each of 12 subjects. One electrode placement was the standard placement of one electrode above each eyebrow (referred to as the horizontal placement). For the other placement, electrodes were positioned vertically above only the left eyebrow (referred to as the vertical placement). Comparisons between the measures of EMG using the two placements were assessed for three different levels of biofeedback-influenced EMG activity.The horizontal and vertical EMG measures were found to be positively correlated both for the entire group and for individual subjects. Also, the two measures of EMG were positively correlated at three different levels of EMG, i.e., high, medium, and low. Comparisons of horizontal and vertical EMG indicated that horizontal EMG was consistently higher than vertical EMG at all levels of EMG. These findings suggest that placement of EMG electrodes is a very important variable in accurately measuring the magnitude of muscular electrical activity. However, if repeated measures of EMG are used to evaluate changes in muscle tension, and electrode placement is consistent across conditions, electrode placement is of only marginal importance.

    Effect of Feedback Delay Upon Learned Heart Rate Control (1979)

    Notes: The effects of heart rate feedback delay upon bidirectional heart rate control were determined by comparing four groups of 10 subjects who received either: a) immediate feedback, or b) feedback that was delayed by 1.4 sec, 5 sec, or 14 sec. All subjects received 3 sessions of training which included 3 within-session phases, i.e. 2 (pre and post-feedback) Instructional Control phases during which subjects were instructed to speed or slow heart rate without the aid of feedback, and a Feedback phase during which bidirectional heart rate control was assisted by analogue heart rate feedback. Heart rate, chin EMG, and respiration rate were recorded during all phases.The results indicated that the magnitude of heart rate increases and decreases was systematically influenced by differing amounts of feedback delay. For increasing and decreasing heart rate, the group receiving immediate feedback showed superior heart rate control in comparison to groups which received feedback that was delayed by 14 sec. The strongest effects of feedback delay were evident during Feedback and the final Instructional Control phase. Only the group receiving immediate feedback improved HR control during Feedback and post-feedback Instructional Control phases.These findings were discussed in terms of a motor skills learning model for learned HR control. It was concluded that while many of the same parameters influence HR and motoric behavior, the two responses should not be regarded as equivalent.

    Notes: Abstract The experimental literature on the use of biofeedback with heart rate and blood pressure, published since 1972, was reviewed and summarized along several dimensions: magnitude of change, effects of extended training, type of feedback, temporal feedback factors, motivational factors, instructional effects, individual differences, and the mediation/specificity issue. The research on biofeedback and heart rate was found to be fairly well developed. Research on biofeedback and blood pressure, however, was found to be much less advanced. Moreover, most of the studies were done with hypertensive subjects.

    Temperature biofeedback and relaxation training in the treatment of migraine headaches (1979)

    Topics: Medicine
    Notes: Abstract In a previous controlled group outcome study, a comparison of temperature biofeedback with progressive relaxation indicated that relaxation training was more effective in reducing migraine headache activity at the end of treatment. However, follow-up data obtained at 1, 2, and 3 months after the completion of treatment showed no difference between the two groups on any dependent measure. In the current study, 18 of 26 subjects who completed treatment in the original investigation collected headache data and completed a headache questionnaire I year subsequent to the conclusion of treatment in order to evaluate the long-term effectiveness of the two treatments. The results indicated that gains achieved in the reduction of headaches during both treatments were maintained at a 1-year follow-up. With the exception of medication consumption (for which relaxation training led to better long-term results) the 1-year follow-up data reveal no differential efficacy for temperature biofeedback or progressive relaxation in treating migraine headaches.

    Notes: Abstract Recent studies have found that the eating disorders can best be conceptualized as multidimensional. Four factors have consistently emerged from factor analytic studies of eating disorder symptoms: dietary restraint, bulimic behaviors, neurotic personality characteristics, and body image/body dysphoria. Confirmatory factor analysis was utilized to determine if this four-factor structure of eating disorder symptoms would be found in a sample of college women. Principal components analysis extracted four factors which were supported with a confirmatory factor analysis procedure. These four factors were negative affect and body dysphoria, bulimic behaviors, restrictive eating, and body image. The negative affect and body dysphoria factor was positively correlated with the other factors (i.e., bulimic behaviors, restrictive eating, and body image). This factor structure was similar to the factor structure found in samples of patients with bulimia and anorexia nervosa, except that the factors were more highly intercorrelated in the nonclinical sample. Results suggest that the measures of eating disorder symptoms used in this investigation are measuring the same multidimensional constructs in clinical and nonclinical subjects.

    Bulimia, dietary restraint, and concern for dieting (1989)

    Notes: Abstract The concept of dietary restraint has recently been used to explain binge-eating in dieters. It has been proposed that the violation of various restraint rules typically leads to hinging in individuals exhibiting high dietary restraint. This study examined the role of dietary restraint in a clinical sample of bulimics. After eating a preload to break dietary restraint, bulimic binge-eaters (those who binge but do not purge) were found to eat significantly more than bulimics who binged and purged (bulimia nervosa) and significantly more than normals. In addition, purging bulimics were found to have more concern about dieting than binge-eaters, while normals were found to have less concern about dieting and less anxiety about eating than both bulimic groups. These data suggest that the psychopathology of bulimia nervosa and bulimia (binge-eating) may be substantially different. It was proposed that the most distinguishing characteristic may be the preoccupation with dieting, weight, and body size, which is more extreme in bulimia nervosa.

    Notes: Abstract In the recent revision of the DSM-III, the diagnosis of “bulimia nervosa” includes the criterion of “persistent overconcern with body shape and weight,” which may be conceptualized as a form of body-image disturbance. The new diagnostic criteria for bulimia nervosa include only those who exhibit a binge-purge eating patern, excluding binge-eaters who, in the older DSM-III, receive a diagnosis of bulimia. This study was conducted to investigate body-image disturbances in bulimia nervosa and simple bulimia (i.e., binge-eating without purging). The experimental design included two control groups, obese and normal subjects, in order to determine whether the binge-eater had body-image disturbances different form those of normal and overweight samples. The study evaluated 596 subjects (417 normals, 109 bulimia nervosa subjects, 50 binge-eaters, and 30 obese subjects) in terms of perception of current body size and selection of ideal body size. Results indicated that the bulimia nervosa group selected a current body size larger than that selected by normals and an ideal body size smaller than that chosen by normals. However, bingeeaters did not differ from the obese control group on either current or ideal body size. These results are discussed in terms of the recent debate regarding the diagnosis of bulimia nervosa and sociocultural influences upon body-image disturbances.

    Notes: Abstract This investigation evaluated a method for the prospective assessment of the symptoms of premenstrual syndrome (PMS). The American Psychiatric Association has proposed a diagnostic category for PMS in the DSM-III-R entitled late-luteal phase dysphoric disorder (LLDD). The criteria for this disorder include prospective documentation of at least two “symptomatic cycles.” Two groups of women were studied, one group that met the DSM-III-R diagnostic criteria for LLDD and a comparison group that did not. Subjects recorded symptoms related to PMS for two menstrual cycles. A clinically significant worsening of symptoms was defined as a symptom increase during the premenstruum of greater than one standard deviation above normal. These effect sizes were then used to determine if the subject met the DSM-III-R criteria for prospective confirmation. Data analysis showed that although the LLDD group showed evidence for PMS in several symptom groups, only a minority (31%) met the requirement of prospective confirmation of significant PMS symptoms for the two cycles recorded. These results were discussed in terms of the need for prospective behavioral assessment of LLDD and the implications of these findings for past and future research.
