An examination of methods for producing relaxation during short-term laboratory sessions

Reductions in psychological and physiological correlates of tension produced by various muscle relaxation training techniques were examined during a short-term laboratory session. Two studies are described involving a combined total of one hundred subjects receiving either abbreviated progressive relaxation, visual, auditory, or tactile electromyographic (EMG) biofeedback procedures. The Anxiety Differential was administered before and after the laboratory session. Heart rate, respiratory rate, skin conductance, systolic blood pressure, and frontalis and dominant forearm extensor EMG measures were obtained before, during, and after administration of relaxation training. Results indicated feedback in the tactile modality to produce overall reductions in tension comparable to those produced by progressive relaxation. Overall reductions in tension displayed by both progressive relaxation and tactile feedback were generally greater than reductions shown by visual or auditory feedback procedures. Interpretations suggest that certain forms of EMG feedback may offer an alternative to progressive relaxation techniques for producing short-term reductions in tension. Feedback modality is further indicated as a potentially important variable during relaxation training using the EMG feedback technique.     

Male Violence Toward Females: Victim and Aggressor Variables

Two studies investigated the effect of exposure to psychology on male and female college students' pcrceptions of the truthfulness of psychologists as researchers. Study I (N # 72) compared the perceptions of freshmen in general psychology courses at the beginning and the end of the semester. Study II (N # 70) compared the perceptions of upperclassmen who had had no psychology courses with upperclassmen who had had at least five psychology courses. Both studies found that students with training in psychology perceived psychologists to be significantly less truthful than students with no training in psychology.     

Repeated exposure of flight phobics to flights in virtual reality

The present study examined the effects of repeated exposure of flight phobics to flights in virtual reality (VR). Flight phobics were randomly assigned either to complete one VR test flight followed by four VR exposure flights (VR group; N=15) in one lengthy session or to complete one VR test flight followed by a lengthy relaxation training session (relaxation group; N=15). All participants completed a second VR test flight at the end of the session. Fear reports and physiological fear reactions (heart rate, skin conductance level) during VR exposures were registered, and fear of flying was assessed psychometrically from 3 weeks before to 3 months after exposure. Exposure to VR flights elicited subjective and physiological fear responses in flight phobics, and these responses attenuated within and across VR flights. Fear reduction associated with repeated VR exposure was greater than fear reduction caused by relaxation training. Fear of flying improved in both treatment groups, but several outcome measures indicated greater effects in the VR treated group than in the relaxation group. These findings indicate that exposure in virtual reality may offer a new and promising approach for the treatment of fear of flying.     

Super-learning of Causal Judgements

In three experiments, participants learned which of a variety of foods were capable of causing an allergic reaction in a hypothetical patient during training in which a compound of a treatment and a target food cue was paired with the reaction. In Experiment 1 the causal ratings of the target cue were increased if the treatment cue was pretrained as a preventative cause of the reaction. Experiments 2 and 3 demonstrated that the magnitude of this superlearning is unaffected by the order of compound and treatment cue training. The final study also showed that forward super-learning is not induced solely by simple exposure to the treatment cue prior to compound training but, rather, depends upon training the treatment cue as a preventative cause, whereas retrospective super-learning may be due merely to exposure of the treatment cue. These results are problematic for contingency-based accounts of causal induction but accord with modified and extended associative theories.     

The role of physiological attention-focusing in the relaxation treatment of sleep disturbance,general tension,and specific stress reaction

Three experiments comparing the effects of muscle tension-release relaxation with vs without physiological attention-focusing and no-treatment on (a) sleep disturbance, (b) general tension, and (c) a variety of time estimation, heart rate perception, and stress reaction measures, are reported. The two relaxation conditions produced equivalent reductions in latency to sleep onset reports, suggesting the importance of tension-release in the relaxation treatment of sleep disturbance. Relaxation without physiological attention-focusing was unexpectedly superior to the other relaxation condition in reducing reported daily tension, supporting Denny's (1976) hypothesis that pervasive anxiety may be a function of anxiety conditioned to relaxation-produced cues. Sleep disturbed subjects over-estimated elapsed time, and relaxation training improved accuracy of time estimation. Several additional differences between sleep and tension subjects and among the three treatment conditions on physiological activity during stress are reported and discussed.     

The effect of tape-recorded relaxation training on well-being,symptoms, and peak expiratory flow rate in adult asthmatics: A pilot study

Abstract

Evidence indicates that psychological stress plays a role in precipitating and exacerbating asthma symptoms and suggests that relaxation techniques aimed at reducing stress and autonomic arousal leads to symptom reduction. This study explored the effect of a tape-recorded relaxation intervention on well-being (mood and stresson). asthma symptoms, and a measure of pulmonary function (PEFR). Twenty adult asthmatics were studied for 21 days in their natural environment using a multiple baseline design. Self-administered relaxation training (including both breathing exercises and muscle relaxation) led to decreased negative mood and stressor report. Reporting of asthma symptoms decreased over time, and PEFR was increased by relaxation training. Asthma medication use was unchanged. Results suggest that tape–recorded relaxation training positively impacts well-being, asthma symptoms. and PEFR in a naturalistic setting. Further study of the potential use of inexpensive tape-recorded interventions in chronic illness is warranted.     

Treating Speech Anxiety in Youth: A Randomized Controlled Microtrial Testing the Efficacy of Exposure Only Versus Exposure Combined With Anxiety Management Strategies

CBT for anxious youth usually combines anxiety management strategies (AMS) with exposure, with exposure assumed to be critical for treatment success. To limit therapy time while retaining effectiveness, one might optimize CBT by restricting treatment to necessary components. This study tested whether devoting all sessions to exposure is more effective in reducing speech anxiety in youth than devoting half to AMS including cognitive or relaxation strategies and half to exposure. After a 6-week waitlist period, adolescents with speech anxiety (N = 65; age 12–15; 42 girls) were randomized to a 5-session in-school group-based CBT training consisting of either (1) exposure-only (EXP+EXP) or (2) cognitive strategies followed by exposure (COG+EXP) or (3) relaxation strategies followed by exposure (REL+EXP). Clinical interviews, speech tests, and self-report measures were assessed at pretest, posttest, and follow-up. For all conditions (a) the intervention period resulted in a stronger decline of speech anxiety than waitlist period; (b) there was a large sized reduction of speech anxiety that was maintained at six-week follow-up; (c) there was no meaningful difference in the efficacy of EXP+EXP versus COG+EXP or REL+EXP. These findings suggest that devoting all sessions to exposure is not more effective than combining exposure with AMS. AMS appeared neither necessary for CBT to be effective, nor necessary for youth to tolerate exposure. This indicates that CBT can be optimized by restricting treatment to exposure.     

Effects of frontalis tension level on discrimination task accuracy and reaction time

The frontalis muscle is a focal point of many relaxation training programmes, so the effects of varying frontalis tension levels on concurrent task performance need consideration when recommending in situ muscle relaxation. Two experiments are reported; performance on a discrimination task was examined across high, moderate, and low induced frontalis tension. When length of exposure to the task stimuli was unlimited, accuracy of discrimination was affected by tension; when exposure was limited, reaction time was affected. In both experiments the high frontalis tension resulted in better performance than the other levels. Implications for the practice of in situ relaxation are considered.     

The Potential of Relaxation Training for the Hyperkinetic Training for the Hyperkinetic Trainable Mentally Retarded Child

The literature addressing relaxation training for retarded individuals is limited. Adding to the controversy over the benefits of relaxation training is the failure of many researchers to document levels of relaxation through physiological measures. The following single-subject study was designed to determine if relaxation techniques could be learned by a hyperkinetic, moderately retarded child based on a predetermined criteria, and the extent to which these techniques resulted in quantifiable muscle relaxation. The child was able to learn the relaxation techniques to criteria within five sessions. Reduced levels of muscle tension as indicated by an electromyogram were evident during relaxation training sessions when compared with baseline sessions. Implications of these techniques for classroom use are discussed.     

Cognitive-Behavioral Treatment of Social Phobia

Social phobia can be a chronic disorder, capable of restricting a client's social and occupational functioning. Cognitive-behavioral therapy can help many clients learn to overcome their social inhibitions, and make lasting changes in their interpersonal style. Cognitive-behavioral therapy for social phobia includes four general components for helping clients learn to manage their social anxiety. First, therapy begins with the establishment of a sound therapeutic alliance, a focus on assessment, diagnostic interviewing, and education regarding anxiety symptoms and their treatment. Second, the therapist helps clients to develop competence in social skills, relaxation training, and cognitive restructuring. Third, therapy uses exposure to social situations in order to help clients confront their fears and refine their coping skills. Fourth, relapse prevention strategies are used to help clients learn to tolerate feelings of discomfort and confront challenging social interactions. This treatment framework can be adapted to the specific needs of different clients.     

Motor and cognitive relaxation in the desensitization of anger

Three procedures were assessed to determine their effectiveness in reducing anger. The procedures were: desensitization, desensitization with cognitive relaxation, and desensitization with the absence of relaxation training. Anger was aroused by exposing white males, selected for their reports of anger toward blacks, to black racial stimuli. The desensitization group reported reductions in anxiety and disgust relative to a no-treatment control group. Therapist ratings indicated reductions in anger for Ss in both the desensitization and desensitization with cognitive relaxation groups. In addition the latter group reported reductions in anger concurrently with increases in diastolic and systolic blood pressure. Post-hoc analyses indicated that Ss for whom desensitization was most effective reported less anger after the pretreatment anger arousal procedure, greater depth of relaxation during treatment, and were liked more by their therapists. These Ss also reported a greater reduction in ethnocentrism and a trend toward lower overt hostility following treatment.     

Enhancing the Efficacy of Cognitive Bias Modification for Social Anxiety

Cognitive bias modification for interpretation (CBM-I) is a promising treatment modality for social anxiety disorder, but effect sizes are relatively small across investigations (Hallion & Ruscio, 2011). Additionally, the extent to which CBM-I impacts other cognitive, emotional, and behavioral outcomes is unclear. This study investigated whether two empirically supported treatment components for anxiety disorders, imaginal exposure (IE) and relaxation, augment the effects of CBM-I and increase the extent to which the effects of CBM-I generalize to behavioral and affective outcomes. We randomly assigned 111 undergraduate students with social anxiety to undergo IE, relaxation, or neutral thinking prior to CBM-I, then measured their interpretation biases, as well as their speaking time, anxiety, and subjective evaluations of performance during a speech task. Results indicated that individuals who received IE prior to CBM-I evidenced more adaptive interpretation biases and less behavioral avoidance during the speech task than did individuals who engaged in relaxation or neutral thinking. However, they did not report differential anxiety, habituation, or evaluations of their performance on the speech task. These findings suggest that the combination of CBM-I with adjunct components that target behavioral, rather than cognitive, mechanisms can facilitate transfer of the effects of CBM-I to reducing behavioral avoidance.     

Effects of relaxation instructions on the electromyographic responses of abstinent alcoholics to drinking-related stimuli

Viewed from a behavioral perspective alcoholism is a behavioral disorder which should be influenced by the same range of environmental and historical variables which affect other operant behaviors. Therefore, environmental stimulus circumstances should play a significant role in influencing alcoholics' disposition to drink. In particular, stimuli which have previously been associated with drinking behavior should come to exert some controlling influence over subsequent disposition to drink. Relapse to substance abuse is often believed to be precipitated by exposure to stimulus circumstances previously associated with the drug or its use. This hypothesis has received its greatest emphasis in the area of narcotics abuse (Wikler, 1965). but presumably it is relevant also to the case of alcohol abuse. Research concerning abusers' reactions to alcohol-related or drinking-related stimuli has been minimal. Ludwig et al. (1974) have presented data suggesting that alcohol-related stimuli interact with priming doses of ethanol to increase alcoholics' disposition to drink. Miller et al. (1974), however, failed to observe a significant effect of drinking-related stimuli upon alcoholics' disposition to drink.

In the field of behavior therapy, relaxation and stimulus-exposure techniques (e.g. systematic desensitization) are often recommended as techniques for reducing the effect of environmental stimuli upon an individual's behavior. However, data are lacking concerning the effect of relaxation training upon alcoholics. The present study uses psychophysiological procedures to investigate three issues concerning the effect of drinking-related stimuli and relaxation instructions upon alcoholics: (1) the effect of a single session of systematic relaxation instructions upon the electromyographic tension levels of abstinent alcoholics; (2) the effect of drinking-related auditory stimuli upon the electromyographic tension levels of abstinent alcoholics; and (3) the influence of prior relaxation instructions upon the EMG responses of abstinent alcoholics exposed to drinking-related stimuli.     

Modification of Cognitive-Behavioral Techniques in the Treatment of a Five Year-Old Girl with Social Phobia

Social phobia is a debilitating anxiety disorder that often goes undetected in young children, but can be effectively treated with cognitive-behavioral interventions. For children and adolescents, treatment usually includes education, social skills training, cognitive restructuring, relaxation training, and exposure. However, for very young children who present with social phobia, it is necessary to adapt treatment to the developmental level of the child. A case illustration demonstrates the way in which cognitive behavioral treatment (CBT) was modified for the treatment of a five year-old girl with social phobia. Several modifications were made, including utilizing novel exposure techniques and emphasizing parent management training in order to promote generalization of treatment gains outside of session.     

Critical procedural variables related to the physiological effects of progressive relaxation: a review.

Twenty-five investigations of the physiological effects of progressive relaxation training were classified according to whether relaxation was found to be superior or equivalent to control conditions. The two sets of studies differed significantly on number of training sessions and in the use of taped vs live administration of training, and they tended to differ in the use of normal vs patient samples. The likelihood of producing significant physiological reductions via progressive relaxation appears to be greater when multi-session, subject-controlled training is conducted with subjects for whom physiological activity contributes to a presenting. clinical problem.     

The importance of home practice for progressive relaxation training

The efficacy of home practice assignments was evaluated as a component of standardized progressive relaxation training. Subjects reporting general anxiety and tension problems were assigned to either a home practice relaxation, no home practice relaxation or wait-list control condition. Treatment was conducted for 10 sessions over a 5-week period. In addition, subjects in both conditions engaged in in-vivo application of their relaxation skills during a final 2-week application period. Group comparisons showed that both progressive relaxation conditions significantly improved on daily self-monitored general anxiety and tension levels relative to the wait-list control condition. Group analyses of percent subject improvements supported the effectiveness of home practice assignments, especially during the application period. No systematic differences between groups, on physiological and self-report variables, were found during several laboratory relaxation evaluation sessions. This study supports the contribution of home practice assignments to progressive relaxation training.     

EMG biofeedback training, relaxation training, and placebo for the relief of chronic back pain

24 patients with chronic low back pain were randomly assigned to three treatment conditions: EMG biofeedback, relaxation training, and a placebo condition. Patients were seen for eight sessions and were evaluated before Session 1 and after Session 8. Eight analyses of covariance which were adjusted for age and pretest scores were computed on the final scores to find which variables could detect significant difference between treatments. Age was included as a covariate because the differences in age between conditions were significant. Four variables with significant and nearly significant differences were chosen for analysis. The second set of analyses identified the nature of the differences among the three conditions. These included a priori planned comparisons among conditions, and paired t tests. Relaxation-trained subjects were significantly superior to subjects in the placebo condition, in decreasing pain during the function test, increasing relaxation, and decreasing Upper Trapezius EMG. They were superior to EMG Biofeedback training in increasing reported activity. Both Relaxation and EMG trained subjects were able to reduce Upper Trapezius EMG by Session 8. Relaxation-trained subjects showed significant change on eight of the 14 possible comparisons for each treatment condition. EMG biofeedback training showed significant favorable results in only one condition; the placebo condition showed no significant results. Relaxation training gave better results in reducing EMG and pain, and in increasing relaxation and activity than either EMG biofeedback alone or a placebo condition.     

Sequential comparisons of relaxation training and biofeedback in the treatment of three kinds of chronic headache or,the machines may be necessary some time of the time

Two studies are reported in which patients with chronic headache, who did not improve significantly as a result of a 10-session, 8-week relaxation training program, were subsequently treated with biofeedback. For the tension headache sufferers, 36% of the relaxation non-responders showed significant improvement with frontal EMG biofeedback training. For those with vascular headaches, 44% of the relaxation non-responders showed significant improvement with thermal biofeedback. Vascular headache patients with combined migraine and tension symptoms did better than those with only migraine. Psychological test scores significantly differentiated successful vs non-successful biofeedback responders.     

Cognitive-Behavioral Treatment of Panic Disorder: Confronting Situational Precipitants

Panic Disorder is a common, debilitating psychological problem which is often effectively treated through cognitive behavioral approaches. Cognitive-behavioral treatment incorporates education, relaxation training, cognitive therapy, behavioral exposure, and relapse prevention treatment strategies. A case illustration demonstrates how cognitive-behavioral treatment facilitated a client's ability to identify and confront situational precipitants to panic in a gradual and systematic manner. A therapeutic and collaborative relationship provided the foundation for treatment, while education helped the client to understand the vicious cycle between somatic symptoms, catastrophic thoughts, and anxiety. Passive relaxation training incorporated deep breathing, muscle relaxation, and positive imagery generated from the client's own experience. Cognitive restructuring involved identifying automatic thoughts related to panic, challenging dysfunctional beliefs associated with the client's depression and low self-esteem, and generating alternative ways of thinking. Behavioral exposure (e.g., imaginal exposure, behavioral rehearsal, in vivo techniques) helped the client gain a greater sense of mastery over panic attacks triggered by his fear of hypodermic needles. Over the course of treatment, the frequency and intensity of the client's panic attacks decreased. Furthermore, the client's sense of mastery over panic had beneficial effects on his mood and self-esteem. Treatment gains were maintained at one-year follow-up.     

Effect of brief mindfulness and relaxation inductions on anxiety,affect and brain activation in athletes

The mindfulness-based intervention and psychological skills training are often used for maintaining the mental health or reducing undesirable mental states in athletes. However, their differences in acute effects on mental health and underlying neural mechanism are not well understood. Therefore, the purpose of the current study was to examine the differential effects of brief mindfulness induction (MI) and relaxation induction (RI) on state anxiety, affect and brain activation. Thirty-five track and field athletes were recruited for this study. Using a within-subjects crossover design, participants underwent three conditions that incorporated two 30-min experimental conditions (i.e., MI or RI) and a control condition. State anxiety and affect were assessed before and after intervention, and brain activation (i.e., theta, alpha bands) were recorded by electroencephalography (EEG) during each 30-min condition. Repeated measures analysis of variance revealed that MI and RI similarly reduced state anxiety and negative affect from pre-test to post-test compared to the control condition. In terms of positive affect, there were no significant differences among the three conditions across times. Furthermore, participants exhibited higher frontal theta power during the MI and RI than control condition, whereas no differences in alpha power were observed among conditions. The current study provides initial evidence from an electrophysiological perspective that brief MI and RI both improve the negative psychological states in individual sport athletes through similar neural mechanisms. Nevertheless, the moderating effects of training experiences and long-term interventions on mental state and EEG activity in athletes need further investigation in future studies.
