The effect of Multi Convergent Therapy on the psychopathology,mood and performance of Chronic Fatigue Syndrome patients: A preliminary study

Objectives: Multi Convergent Therapy combines approaches such as Cognitive Behaviour Therapy and Graded Exercise Therapy in an holistic treatment of Chronic Fatigue Syndrome. Initial follow‐up data showed that patients were benefiting from this individualised form of therapy. The objective of the present study was to evaluate this Multi Convergent approach, developed at a specialised Chronic Fatigue Syndrome Outpatient clinic in Cardiff, and compare it to Relaxation Therapy and control groups using multiple outcome measures. Design: Thirty‐five participants fitting the Centre for Disease Control criteria for Chronic Fatigue Syndrome were recruited from two outpatient clinics and members of our existing patient panel. Patients were assigned to Multi Convergent Therapy (N=12), Relaxation Therapy (N=14) or recruited as controls (N=9). Methods: Each patient completed a battery of mood and performance tasks along with comprehensive set of questionnaires at baseline, post‐treatment and at six‐month follow‐up. These measures had been validated in previous studies on untreated patients and matched healthy controls. Results: Patients attending the Multi Convergent Therapy clinic showed statistically significant improvements in many of our measures. Most importantly we have produced data indicating that Multi Convergent Therapy provides improvements in objective measures of psychomotor performance and cognition. Discussion: The outcomes of this small study are encouraging. Multi Convergent Therapy has not only produced results indicating significant improvements in standardised questionnaire based measures but also in objective cognitive performance tasks. The next step would be to assess Multi Convergent Therapy at the primary medical care level, with a greater number of patients to further evaluate its efficacy as a treatment for Chronic Fatigue Syndrome.     

Exercise Dependence: Diagnostic and Therapeutic Issues for Patients in Psychotherapy

Health promotion and exercise is recognized as an important ingredient in health maintenance. Within the diagnostic category of obsessive-compulsive disorders has been the increased recognition by clinicians of a phenomena best described as exercise dependence. Reviewed herein is its definition, theoretical framework and a spectrum of factors often associated with exercise. Realizing that exercise dependence as a clinical entity is not yet recognized in either the International Classification of Disorders (ICD-9) or the Diagnostic and Statistical Manual (DSM-IV-R), proposed criteria for its inclusion are offered. Where a pattern of behavior shows the presence of symptoms consistent with exercise dependence, clinical diagnosis should be made to assure that appropriate treatment might be offered to manage the condition and continue to make exercise an important part of a healthy lifestyle. Diagnostic and therapeutic considerations are offered for the contemporary psychotherapist.     

Effects of chronic exercise on attentional bias among individuals with methamphetamine use disorder

BackgroundIndividuals with substance use disorder show attentional bias toward drug-related cues, which may be associated with attentional control deficits. Although exercise improves attention in healthy people, whether individuals with substance use disorder also benefit is unknown. We explored the effects of chronic exercise on behavioral and neural correlates of attentional bias in men with methamphetamine use disorder.MethodsSixty-one such men were randomized to high- or moderate-intensity exercise or to a control group with little exercise for 12 weeks. The dot-probe task assessed attentional bias before and after exercise intervention, with event-related potentials recorded during the task to determine underlying neural mechanisms.ResultsAttentional bias scores and event-related potential amplitudes significantly decreased after high- or moderate-intensity chronic exercise, but not in controls.ConclusionsChronic exercise reduces attentional bias in individuals with methamphetamine use disorder by enhancing early identification of drug-related stimuli and diverting attention to reduce conflict processing.     

The dynamics of success and failure: how post-behaviour evaluations relate to subsequent exercise intentions and behaviour

Objective: Exercise behaviour change involves multiple experiences with success and failure. The Model of Action Phases (MAP) offers a dynamic account of how success and failure influence both immediate evaluations and future decisions and actions. However, predictions from the MAP have not been formally tested.

Design: A longitudinal daily diary study was used to examine how post-behaviour evaluations of exercise success and failure influence subsequent exercise intentions and behaviour. Participants (N = 104) set exercise goals, and then kept a daily online exercise diary for four weeks.

Main outcome measures: Participants self-reported exercise behaviour, affective response to exercise, self-evaluations after success or failure at following through on intentions to exercise, and intentions to exercise in the next week.

Results: Multilevel modelling revealed significant within- and between-participant relationships among post-behaviour evaluations, intentions and subsequent behaviour. Findings supported MAP-derived predictions about how success and failure at exercise are associated with feelings about exercise and the self, and inform subsequent exercise intentions and behaviour.

Conclusion: Positive post-behaviour evaluations of success or failure may stabilise positive intentions and aid maintenance of exercise behaviour. Implications of these MAP-based findings for intervention design are discussed.     

Walking versus biofeedback: a comparison of acute interventions for stressed students

Background: High rates of stress-related problems in college students and low utilization of treatment options demonstrate the need for effective stress-reducing interventions that can be self-regulated. This study compared the effect of brief paced-breathing with biofeedback and exercise interventions on heart rate variability, state anxiety and affect. Methods: Students (n?=?32) with high levels of perceived stress completed three 10-min interventions on separate days: paced-breathing with biofeedback (Biofeedback), a self-paced walk (Exercise), and an attention control condition of quiet studying (Quiet Study). Anxiety and affect were measured before (Pre), immediately after (Post0) and 15 mins after (Post15) the intervention. Heart rate variability was measured pre- and post-intervention using electrocardiogram. Results: Biofeedback reduced anxiety more than the exercise condition (Pre to Post0: Biofeedback d?=??0.48, Exercise d?=??0.13). Secondly, Exercise temporarily increased energy (Pre to Post0: d?=?0.67), whereas Biofeedback temporarily increased calmness (Pre to Post0: d?=?0.51). All conditions significantly increased total heart rate variability (p?Conclusions: Biofeedback and Exercise interventions improved emotional states in high-stress college students, but the type of change observed (i.e. energizing, calming or anxiety reducing) depended upon the condition.     

Post-exercise pulse pressure is a better predictor of executive function than pre-exercise pulse pressure in cognitively normal older adults

Exercise “stress tests” are widely used to assess cardiovascular function and to detect abnormalities. In line with the view of exercise as a stressor, the present study examined the relationship between cognitive function and cardiovascular activity before and after light physical exercise in a sample of 84 non-demented community-dwelling older adults. Based on known relationships between hypertension, executive function and cerebral white matter changes, we hypothesized that greater post-exercise reactivity, as indexed by higher pulse pressure, would be more related to worse performance on frontal-executive tasks than pre-exercise physiologic measures. All participants were administered a comprehensive neuropsychological battery and underwent a Six Minute Walk Test (6MWT), with blood pressure (BP) measures obtained immediately before and after the walk. Pulse pressure (PP) was derived from BP as an indicator of vascular auto-regulation and composite scores were computed for each cognitive domain assessed. As predicted, worse executive function scores exhibited a stronger relationship with post-exercise PP than pre-exercise PP. Results suggest that PP following system stress in the form of walking may be more reflective of the state of vascular integrity and associated executive dysfunction in older adults than baseline physiologic measures.     

The relationship between habitual physical activity status and executive function in individuals with Alzheimer’s disease: a longitudinal,cross-lagged panel analysis

To determine whether habitual physical activity status specifically influences executive function change in Alzheimer’s disease (AD) over 1 year. In this longitudinal cohort study, 45 participants with AD were recruited and provided follow-up data approximately 1 year later. Executive function measures (map search task, digit symbol substitution task, controlled oral word association task, verbal fluency task) and habitual physical activity measures (Physical Activity Scale for the Elderly (PASE) and handgrip strength) were taken at baseline and follow-up. Individual composites were subsequently created. Additional demographic, lifestyle, and neuropsychiatric measures were also taken. In a structural equation model (χ²(26) = 9.84, p = .998, comparative fit index = 1.00, root mean square error of approximation = .00), a significant association was found between habitual physical activity and executive function change (β = .27, p = .04). In a cross-lagged panel analysis, a significant path was found between the PASE score and executive change (β = .22, p = .01). As higher habitual physical activity levels were associated with reduced executive function change, the promotion of low-intensity habitual physical activities in individuals with a diagnosis of AD may be warranted. Further research is needed, however, to explore the impact of habitual physical activity on the trajectory of change across cognitive domains, and how this relates to the progression of the underlying pathology associated with this disease.     

Move2Love and Vibrancy: Community Dance/Fitness

The Move2Love program demonstrates the feasibility of establishing community-based programs involving dance and exercise to support physical and social well-being in older women. The social fitness program has been running continuously for 23 years. It currently involves 125 to 175 women between the ages of 54 and 94 in weekly rhythmic training sessions. In addition to meeting the initial goals of addiction avoidance in an at-risk population, this program has contributed to the well-being of participants, both by lowering disease burden, and by increasing physical, social, and psychological fitness. This article describes the program and explores the reasons that it has continued to work for over two decades. It also demonstrates the value experienced by participants in their own words. The Move2Love program could serve as a feasibility pilot for other communities wishing to create sustainable, salutary activity programming to enhance the well-being of senior women.
