The effect of specific hypnotic suggestions on blood pressure in normotensive subjects

Twenty normotensive subjects participated on a voluntary basis in an experiment designed to study the effects of specific suggestions on blood pressure (BP). After an induction procedure, the experimental group received suggestions presumed to be relatively nonactivating, although capable of lowering or raising BP. A control group was used to record the BP changes over time. All subjects met for one session. Eight subjects from the experimental group met for a second session. Both adaptation and induction resulted in significant BP decreases. A specific suggestion to increase BP gave a significant result when compared to the induction point. There was no significant change from induction to the BP decrease suggestion. Both systolic and diastolic BP behaved in the same way. A second experimental session resulted in no significant change compared with the first session. Also, no significant difference was found in suggestibility scores from the first to the second session. The results are in line with previously published studies.     

The moderating role of proactive coping on the relationship between distress tolerance and elevated blood pressure

This study investigated the moderating role of proactive coping on the relationship between distress tolerance and elevated blood pressure (BP) among Nigerian adults with heart disease. Two hundred and forty hypertensive patients were recruited from the cardiology unit of a university teaching hospital (females = 56.2%%; mean age = 41.09 years, SD = 9.11 years). The participants responded to two self-reported measure including the Proactive Coping Inventory (PCI) and the Distress Tolerance Scale (DTS). Following moderated regression analysis, the results showed that proactive coping moderated the relationship between distress tolerance and elevated BP. The slope of the moderation analysis indicated that the relationship between distress tolerance and mean artery pressure was significantly higher for individuals with low proactive coping, as compared to individuals with higher proactive coping. Unlike reactive ways of coping, which addressed already existing stress, interventions aimed at increasing peoples’ proactive coping could be more efficacious in the management of people with high BP.     

Fixed-interval schedule of cocaine reinforcement: effect of dose and infusion duration

Rhesus monkeys were trained on a fixed-interval 9-min limited-hold 3-min schedule of intravenous cocaine reinforcement. A 15-min timeout followed each reinforcement or limited-hold expiration. An identical schedule of food reinforcement was interspersed in the session to assess rate-modifying effects of the drug infusions not specific to drug reinforcement. In one experiment, response rate for cocaine reinforcement was shown to be a positive function of reinforcement magnitude for a dose range from 0 to 800 ug/kg/inj. At these doses, there was little effect on food reinforced responding except at the highest dose, where responding decreased. Results of the second experiment indicated that increasing the duration of the cocaine infusion produced a change in response rate similar to decreasing unit dose. The response rate change for a given increase in infustion duration was less at a unit dose of 400 ug/kg than at 200 ug/kg.     

Blood pressure responses to hypnotic and nonhypnotic suggestions in normotensive subjects

Forty normotensive subjects participated on a voluntary basis in a study designed to compare the effect of suggestions on blood pressure (BP). Two experimental groups received suggestions presumed to be specific in lowering or raising BP after simple relaxation (relaxation group) or hypnotic induction (hypnotic group). A control group was used to record the BP changes over time. The time variable was significant for both systolic (SBP) and diastolic blood pressure (DBP). Induction procedures (hypnosis or relaxation) resulted in significant decreases in DBP in both experimental groups. In the control group there was a significant decrease in SBP. A specific suggestion to increase the BP resulted only in DBP increase in the hypnotic group. This group also gave an increase of both SBP and DBP over the entire experiment, whereas the relaxation group resulted in a significant decrease in SBP. There was no significant group variable, indicating no differences between the groups. Further research is needed to enable firm conclusions of the effect of suggestions on BP.     

The Archaic Personality Structure of Alcoholics and Its Implications for Group Therapy

The purpose of this investigation was to obtain a better understanding of the nature of expectations about group psychotherapy, given a consistent body of research pointing to the relationship between specific treatment expectancies and premature termination. The Group Therapy Survey was developed and utilized to assess the predominant beliefs, attitudes, and expectations of 206 clinical and nonclinical subjects toward group therapy. The results of the investigation reflected three major categories of expectations: (1) Group therapy is unpredictable, (2) group therapy is not as effective as individual therapy, and (3) group therapy can be detrimental to participants. Possible explanations for the origin and development of such expectations are entertained, including the publicizing of the more radical aspects of the encounter group movement and other negative portrayals of group therapy in the media and the film industry. Recommendations are offered concerning the use of the survey prior to intake or a pregroup orientation interview in order to tailor a discussion to the prospective client's personality, expectations, and problems.     

Using the Michigan State University Family Therapy Questionnaire for Training

The development of the Michigan State University Family Therapy Questionnaire (MSU/FTQ) is described and a case example given of its use as a training tool. The MSU/FTQ is a relatively exhaustive list of 74 generic, structural, strategic, brief, and trans-generational family therapy interventions culled from the literature and translated into layperson's language. The marital and family therapy client uses it to provide feedback about the effectiveness of therapy by assessing those things theorists consider important about behavior maintenance and systemic change, indicating whether or not specific interventions occurred and their importance.     

An exploratory study on the development of beliefs about symptoms as signals of arterial hypertension

An exploratory study on the development of beliefs about symptoms as signals of arterial hypertension. In spite of hypertension is known as an asymptomatic health problem, most of the people with such a diagnosis are convinced of experiencing very specific symptoms associated to specific changes in blood pressure (BP). In addition, such beliefs may affect treatment adherence. Previous studies have shown that hypertensive patients use the information they considered right about BP symptoms to regulate the type of decisions they follow in adhering to treatment. The aim of this study is to explore specific variables related with the formation of beliefs about symptoms in a sample of 171 hypertensive patients. Results show that 81,3% of the patients perceived specific symptoms related to changes in hypertension as well as that variables related with the development of these beliefs were mostly: (1) the presence of symptoms during the diagnosis process, (2) the occurrence of hypertensive crisis, and (3) the information provided by others concerning the relationships between symptoms and BP changes. The importance of paying attention to the beliefs of specific symptoms as well as to the circumstances related with the formation process of such beliefs is discussed.     

Learning strategy determines auditory cortical plasticity

Learning modifies the primary auditory cortex (A1) to emphasize the processing and representation of behaviorally relevant sounds. However, the factors that determine cortical plasticity are poorly understood. While the type and amount of learning are assumed to be important, the actual strategies used to solve learning problems might be critical. To investigate this possibility, we trained two groups of adult male Sprague-Dawley rats to bar-press (BP) for water contingent on the presence of a 5.0 kHz tone using two different strategies: BP during tone presence or BP from tone-onset until receiving an error signal after tone cessation. Both groups achieved the same high levels of correct performance and both groups revealed equivalent learning of absolute frequency during training. Post-training terminal "mapping" of A1 showed no change in representational area of the tone signal frequency but revealed other substantial cue-specific plasticity that developed only in the tone-onset-to-error strategy group. Threshold was decreased approximately 10 dB and tuning bandwidth was narrowed by approximately 0.7 octaves. As sound onsets have greater perceptual weighting and cortical discharge efficacy than continual sound presence, the induction of specific learning-induced cortical plasticity may depend on the use of learning strategies that best exploit cortical proclivities. The present results also suggest a general principle for the induction and storage of plasticity in learning, viz., that the representation of specific acquired information may be selected by neurons according to a match between behaviorally selected stimulus features and circuit/network response properties.     

Comparing thought suppression and mindfulness as coping techniques for spider fear

The current study compared thought suppression, focused attention (mindfulness) and unfocused attention as strategies for managing spider fear. Spider fearful participants were exposed to a strategy induction before completing a Behavioural Approach Test (BAT). The BAT is a 10 step measurement of how close participants are willing to move towards a spider. Participants were instructed to use what they learned in the pre-BAT induction to help them advance through the steps of the BAT. The results of the study indicated that participants given the thought suppression or the unfocused attention induction moved through significantly less steps of the BAT than did those given the focused attention (mindful) induction. Additionally, the thought suppression group felt significantly more anxious than the focused and unfocused attention groups following completion of the BAT. These results are discussed in terms of the impact of thought suppression on avoidance behaviour in phobias.     

The Effectiveness of an Occupational Therapy Program for Chemically Dependent Adolescents

This research study, conducted at a residential treatment center for chemically dependent and emotionally disturbed youth, was designcd to answer the following questions: is occupational therapy effective in producing behavioral change in the adolescent chemically dependent population and, if so, what are the factors producing the change? An assessment tool was designed and used in conjunction with observations to determine each resident's behavioral status before and after involvement in occupational therapy groups. All residents admitted to James- town wcre involved in a Work Skills Group (focusing on pre- work skill development) and/or a Relationship Skills Group (fo-cusing on interpersonal skill development). The behavioral status was measured by the therapist using a defined rating scale in an interview format. The changc in ratings from pre- to post-treatment was used as the basis for the data analysis. Groups of residcnts were compared to each other on the, variables of age, sex, attendance, rate of goal completion, group membership, and completion and type of occupational therapy goals. The results of the study indicate that rcsidents who attended occupational therapy, were involved in both groups, completed their occupational thcrapy goals, and completed the occupational therapy program demonstrated significant behavioral change, especially in relationship skills. Age and sex variables alone did not produce significant behavioral change.     

Feasibility and effectiveness of school-based relaxation in lowering blood pressure

Progressive muscle relaxation (PMR) is a broadly useful anxiety reduction technique that has been found to lower blood pressure (BP) in essential hypertension. The present investigation is the first to evaluate the feasibility and efficacy of wide-scale PMR instruction as a public health promotion strategy aimed at adolescents. Students (N = 1,400) in Grades 9 and 10 at two large Baltimore City public high schools underwent BP screening; those with BP persistently above the 85th percentile were randomly assigned to (a) 12 weeks daily PMR instruction provided in class for academic credit or (b) a control condition. The latter students had their BP measured at the same frequency as the PMR students and completed the PMR course during the following year. Approximately two thirds of eligible students entered and completed the study. Results demonstrated that treatment students (n = 51) enjoyed daily PMR, mastered the technique, and achieved reduced systolic BP at posttest relative to the untrained controls (n = 59). At follow-up 4 months later, group BP differences were not significant. Implications for use of PMR to promote cardiovascular health are discussed.     

Blood pressure estimation and beliefs among normotensives and hypertensives

Although health professionals believe that blood pressure (BP) is asymptomatic, most diagnosed hypertensives are confident that they experience specific symptoms and emotions that help them detect their BP levels. Several months after screening interviews that elicited subjects' BP beliefs, 14 medicated hypertensives, 15 nonmedicated mild hypertensives (diastolic BP greater than or equal to 90 mm Hg), 39 normotensives, and 13 hypotensives (systolic BP less than or equal to 100 mm Hg) participated in a 1- to 2-hr laboratory experiment that assessed each subject's symptoms, moods, and estimates of systolic BP (SBP) relative to actual SBP levels. Several self-reports and autonomic measures were collected 45 times during and after each of 22 tasks. Subjects never received SBP feedback during the experiment. Within-subject correlations indicated that all subject groups could estimate SBP at levels greater than chance (mean estimated SBP-actual SBP correlation = .25). Further, 68% of the subjects evidenced at least one significant symptom-SBP correlation. Although medicated hypertensives believed they could estimate their BP more accurately than other groups by using their symptoms and emotions, they were actually no more accurate than the other groups. They also evidenced far fewer empirically derived symptom-SBP and emotion-SBP correlations than any other group. Overall, BP beliefs were largely inaccurate. If these erroneous beliefs can be eliminated, subjects may be able to estimate BP fluctuations more accurately.     

The River Model: A Metaphor and Tool for Training New Psychotherapists

A conceptual frame of reference called The River is presented for training of beginning psychotherapists. Using metaphors, trainees are taught specific tools (Equipment) and to identify salient features of the therapy process (Topography) by means of a series of metaphors for the process elements of timing and of level of intervention. Student therapist feedback indicated that this model facilitated learning of how much or little to do at given points in the therapeutic process, and that these metaphors appeared to transcend specific theoretical orientations.     

Targeting adolescent mothers with depressive symptoms for early intervention

Infants of mothers with depressive symptoms show developmental delays if symptoms persist over the first 6 months of the infant's life, thus highlighting the importance of identifying those mothers for early intervention. In Study 1, mothers with depressive symptoms (n = 160) and mothers without depressive symptoms (n = 100) and their infants were monitored to identify variables from the first 3 months that predict which mothers would still be symptomatic at 6 months. A "dysregulation" profile was noted for the infants of depressed mothers, including lower Brazelton scores, more indeterminate sleep, and elevated norepinephrine, epinephrine, and dopamine levels at the neonatal period, and greater right frontal EEG activation, lower vagal tone, and negative interactions at the 3- and 6-month periods. A group of maternal variables from the neonatal and 3-month assessments accounted for 51% of the variance in the mothers' continuing depressive symptoms. These variables included greater right frontal EEG activation, lower vagal tone, and less positive interactions at 3 months, and elevated norepinephrine, serotonin, and cortisol levels at the neonatal stage. In Study 2, a similar sample of mothers with depressive symptoms (n = 160) and without depressive symptoms (n = 100) was recruited and followed to 3 months. Those symptomatic mothers who had values above (or below) the median (depending on the negative direction) on the predictor variables identified in Study 1 (taken from the first 3 months) were then randomly assigned to an intervention or a control group at 3 months. These groups were then compared with each other, as well as with the group without depressive symptoms, at 6 and 12 months. The intervention, conducted from 3 to 6 months, consisted of free day care for the infants and a rehab program (social, educational, and vocational) plus several mood induction interventions for the mothers, including relaxation therapy, music mood induction, massage therapy, and mother-infant interaction coaching. Although the mothers who received the intervention continued to have more depressive symptoms than did the nondepressed mothers, their interactions significantly improved and their biochemical values and vagal tone normalized. Their infants also showed more positive interations, better growth, fewer pediatric complications, and normalized biochemical values, and by 12 months their mental and motor scores were better than those of the infants in the control group.     

Sensory Extenders Versus Meters and Predictors: Clarifying Strategies for the Use of Objective Tests in Family Therapy

Cromwell and Peterson's goal of introducing quantitative testing into family assessment and therapy is laudable; the system they propose--the Multisystem-Multimethod (MS-MM) approach is not. MS-MM is confusing, deceptive, and misleading for clinicians who want to use tests to sharpen their diagnostic assessments and predictions. What is needed is specific theory linking various family processes and individual behaviors, as well as equally specific information about the reliability and validity of the tests. Likewise, the MS-MM approach is completely inadequate for clinicians seeking to use tests to enlarge their clinical imaginations. What is needed is a more down-to-earth examination of the influence of testing on the family therapy system.     

Pain perception as a function of self-focused rumination

Pain sensitivity and tolerance were studied using the cold-pressor technique. A 3 independent groups design was employed using rumination as the independent variable. Group 1 was given a situation in which anger-related self-rumination was introduced. Group 2 was given a self-related rumination task in which anger was not induced. Group 3 received a rumination task not related to the self. In addition, the State-Trait Anger Expression Inventory was given prior to the experiment to test the hypothesis that ratings on the Anger-In subtest would correlate with pain sensitivity. In each group were 6 men and 6 women. Each participant took the anger and another inventory not relevant to the present study before the experiment. An anger measure was taken before and after the experiment for each group to see if the anger induction in Group 1 actually increased anger. There were no differences among the 3 groups on the second anger measure, so differences between Groups 1 and 2 could not be attributed to anger. A 1-way analysis of variance for 3 groups showed a strong main effect on pain tolerance but not pain sensitivity. Groups 1 and 2 were significantly more tolerant of pain than Group 3. The correlation of ratings on the Anger-In (internalized anger) subtest fell short of statistical significance with pain sensitivity and also was not significant for pain tolerance. Results were discussed in terms of the possibility that self-rumination may increase pain tolerance by requiring a greater cognitive load than nonself rumination.     

Ambulatory blood pressure and heart rate in healthy male paramedics during a workday and a nonworkday.

Compared ambulatory blood pressure (BP) and heart rate (HR) in 30 paramedics during a 24-hr workday and a 24-hr nonworkday. During the 24-hr period as a whole, there were no BP differences between the workday and the nonworkday, but HR was higher during the nonworkday than during the workday. Systolic BP (SBP) recorded in the ambulance on the workday was elevated 9.8 mm Hg, compared to SBP recorded in a car on the nonworkday; it was also 7.2 mm Hg higher at the scene of an accident and at the hospital than during nonworkday activities. Ratings of moods in diaries indicated that paramedics felt more unhappiness, stress, and sadness and less feelings of pleasantness at work than at home. Rather than being elevated for the entire 24-hr period, work BP seemed to reflect the relatively high stress associated with specific situations in the work of a paramedic.     

Introduction to Behavioural Family Therapy for families with young children

This paper presents some suggestions for the implementation of Behavioural Family Therapy for families with young children. It attempts to bridge the gap between clinical research and practice by emphasizing the process of therapy delivery rather than the specific content of the behavioural approach. Suggestions for teaching behaviour management skills, contracting and the effective use of rewards and punishments are given. The common mistakes made by those working with Behavioural Family Therapy are addressed, and suggestions for working with single-parent families are given.     

Repeated post- or presession cocaine administration: roles of dose and fixed-ratio schedule

Effects of repeated administration of cocaine to animals behaving under operant contingencies have depended on when the drug is given. Moderate doses given presession have generally led to a decrease in the drug's effect, an outcome usually referred to as tolerance. When these same doses have been given after sessions, the usual result has been no change or an increase in the drug's effects, with the latter usually referred to as sensitization. In the present study, repeated postsession administration of a relatively small dose of cocaine (3.0 or 5.6 mg/kg) to pigeons responding under a multiple fixed-ratio 5, fixed-ratio 100 schedule of food presentation generally resulted in tolerance to the rate-decreasing effects of the drug. When the same dose was given before sessions, little additional tolerance was observed, although some subjects showed further tolerance in the small-ratio component. A regimen of repeated postsession injection of larger (10.0-23.0 mg/kg) doses suppressed key pecking during the session; responding resumed following discontinuation of postsession administrations. Effects of postsession administration of cocaine, therefore, depended on the dose, with smaller doses leading to tolerance and larger ones to suppression of behavior during the session. Effects of postsession drug administration of either small or large doses were not related to whether effects of postsession drug were experienced mainly in the operant test chamber or in the pigeon's home cage. The results with large postsession doses are compatible with a view that the drug acted as a Pavlovian unconditional stimulus, with the session-related stimuli acting as a long-duration Pavlovian conditional stimulus. Tolerance following postsession administration of the smaller doses challenges the view that it depended on experiencing the drug's effects while the arranged reinforcement contingencies were in effect.     

Probability-of-coverage tolerance intervals for the beta binomial

True score tolerance intervals, which are designed to cover a chosen proportion of the conditional distribution of true scores given an observed score, are suggested as alternatives to true score confidence intervals. Using large sample theory, a tolerance interval estimator for the beta binomial is derived. An example indicates that with moderate sample sizes, tolerance intervals with high probability of coverage will not be much wider than when the two beta true score parameters are known.The author acknowledges valuable comments from Richard Sawyer.Most work was completed while the author was at the American College Testing Program.
