RESUMEN

INTRODUCTION: In depression treatment, most patients do not reach response or remission with current psychotherapeutic approaches. Major reasons for individual non-response are interindividual heterogeneity of etiological mechanisms and pathological forms, and a high rate of comorbid disorders. Personalised treatments targeting comorbidities as well as underlying transdiagnostic mechanisms and factors like early childhood maltreatment may lead to better outcomes. A modular-based psychotherapy (MoBa) approach provides a treatment model of independent and flexible therapy elements within a systematic treatment algorithm to combine and integrate existing evidence-based approaches. By optimally tailoring module selection and application to the specific needs of each patient, MoBa has great potential to improve the currently unsatisfying results of psychotherapy as a bridge between disorder-specific and personalised approaches. METHODS AND ANALYSIS: In a randomised controlled feasibility trial, N=70 outpatients with episodic or persistent major depression, comorbidity and childhood maltreatment are treated in 20 individual sessions with MoBa or standard cognitive-behavioural therapy for depression. The three modules of MoBa focus on deficits associated with early childhood maltreatment: the systems of negative valence, social processes and arousal. According to a specific questionnaire-based treatment algorithm, elements from cognitive behavioural analysis system of psychotherapy, mentalisation-based psychotherapy and/or mindfulness-based cognitive therapy are integrated for a personalised modular procedure.As a proof of concept, this trial will provide evidence for the feasibility and efficacy (post-treatment and 6-month follow-up) of a modular add-on approach for patients with depression, comorbidities and a history of childhood maltreatment. Crucial feasibility aspects include targeted psychopathological mechanisms, selection (treatment algorithm), sequence and application of modules, as well as training and supervision of the study therapists. ETHICS AND DISSEMINATION: This study obtained approval from the independent Ethics Committees of the University of Freiburg and the University of Heidelberg. All findings will be disseminated broadly via peer-reviewed articles in scientific journals and contributions to national and international conferences. TRIAL REGISTRATION NUMBER: DRKS00022093.

RESUMEN

RESULTS: We performed random effects meta-analysis We computed a weighted effect size (Hedges' g) for the difference of the absolute scores of the Hamilton Depression Rating Scale between the group given zinc and the group given placebo after 6 and after 12 weeks. We performed subgroup analysis according to whether not it was stated in the original studies that patients in a clinical trial or subgroup within a trial had not reached remission with previous treatment with a standard antidepressant during the same illness episode. After 6 weeks, we obtained the following effect sizes: Overall effect size: Hedges' g = -0.67, p = 0.03. Subgroup with documented non-remission: Hedges' g = - 0.97, p = 0.001. Group without documented non-remission -0.35, p = 0.24. After 12 weeks: Overall effect size: Hedges' g = -1.0, p = 0.03. Subgroup with documented non-remission: Hedges' g = - 1.46, p < 0.001. Group without documented non-remission: Hedges' g = - 0.54, p = 0.07. CONCLUSIONS: We provide preliminary evidence for the efficacy of zinc vs. placebo as an adjunct to antidepressant medication.

RESUMEN

Autism spectrum disorders (ASD) represent a set of long-lasting severe neurodevelopmental conditions and effective therapeutic interventions are needed. Recent research points to the importance of including mindfulness-based elements to improve emotion and body perception in the psychotherapy of patients with ASD. Therefore, we developed a structured group psychotherapy program The Tübinger Training for Autism Spectrum Disorders (Tübinger Training für Autismus-Spektrum-Störungen; TüTASS) which focuses on mindfulness-based training elements. This pilot study accompanying the TüTASS reports the first results on the feasibility of the program with a pre-post comparison of 25 treated children with ASD. The psychometric assessment comprised five standardized questionnaires/ scales evaluating on the basis of parents and patients self-reports the child's social responsiveness, behavior, strengths and difficulties, quality of life, and depressive symptoms before and after training completion. The results indicated that upon training completion, symptoms with respect to emotional and social problems, externalizing behavior, and attentional and schizoid-compulsive behavior substantially declined. In a questionnaire assessing feasibility and quality of the group training, patients and parents found the therapy highly beneficial, especially as to the focus on emotions and body, and strengths and failures. This training program was developed to bridge the gap of lacking mindfulness-based interventions with the aim to optimize the course of ASD, especially with respect to behavioral disturbances and social-emotional problems.

RESUMEN

Mind-body exercises such as Yoga or Qi Gong have demonstrated a wide range of health benefits and hold great promise for employment in clinical practice. However, the psychophysiological mechanism underlying these effects remains unclear. Theoretical frameworks highlight regulation as a characteristic and specific mechanism of mind-body exercise for which empirical evidence is scarce. To investigate the exact nature of this mechanism, we tracked acute changes in autonomic nervous system (ANS) activity and subjective state over a common form of mind-body exercise (Qi Gong). Heart rate variability (HRV) and subjective state were assessed in 42 Qi Gong practitioners from China and Germany during a standard moving Qi Gong exercise (Baduanjin). Relaxation in supine position prior and after the exercise served as a control condition to Qi Gong and to assess changes before and after the exercise. Following Qi Gong, all practitioners reported significantly increased subjective calmness and perceived body activation, attentional focus, and subjective vitality. On the physiological level, a significant decrease of parasympathetic modulation and increase in heart rate indicated a pattern of moderate general physiological activation during Qi Gong. A significant increase in overall RR-interval modulation and cardiac coherence during Qi Gong were indicative of a mechanism of active regulation. Examination of the RR-interval trajectories revealed a rhythmic pattern of ANS activation and deactivation in sync with activating and relaxing segments of the exercise. Significant changes in subjective state, not on the physiological level, before and after the exercise were observed. Significant associations between Qi-Gong-specific beliefs, age, cultural background, and experiential and physiological measures demonstrated the complexity of mind-body exercises as multicomponent interventions. Overall, this study highlights moderate general physiological activation, exercise-dependent rhythmic ANS modulation, and induction of a characteristic state of eutonic calmness as potential psychophysiological mechanisms underlying the health benefits of mind-body exercise.

RESUMEN

BACKGROUND: Sense of coherence (SOC) is a personal resource that allows people to stay healthy in spite of stressful situations. SOC is known to be low in eating disorders. We explored whether SOC correlated with anorexia nervosa (AN) symptoms several years after initial hospitalization for AN, to inform us whether AN treatment concepts could more specifically focus on increasing SOC. METHODS: Former patients were contacted 5-11 years after hospitalization for AN in a German integrative medicine hospital. Participants completed the Eating Disorder Inventory (EDI-2) and the SOC Questionnaire (SOC-13). Hospital records were reviewed. Correlations between EDI-2 subscales and SOC-13 were tested. A t-test was conducted to assess the difference between the SOC-13 and the norm. A median split was performed, dividing SOC scores into two groups and comparing these with EDI-2 subscales. RESULTS: Of 149 previously hospitalized female patients, 83 could be contacted and 68 agreed to participate (46%). 17.6% self-reported that they currently suffered from an eating disorder. The mean follow-up time was 7.2 years. All EDI-2 subscales correlated negatively with the SOC-13 score (p < .01). The mean SOC was significantly lower than the norm (p < .001). In the median split, the lower SOC group had significantly higher scores on all EDI-2 subscales. CONCLUSIONS: Amongst previously hospitalized AN patients, the SOC was lower than a normative sample and correlated with on-going eating disorder symptoms in long-term follow-up. Strengthening SOC as a personal resource should be incorporated as a specific goal in AN treatment and its impact on long-term outcomes evaluated.

RESUMEN

Psychophysiological disorders due to work-related stress continue to be highly costly for health systems and approaches for cost-effective and easily accessible interventions are much needed. Both heart rate variability-biofeedback (HRV-Bfb) and mindfulness-based interventions (MBI) have been empirically shown to reduce stress. This study compares these two interventions in the work context to a wait-list-control-group (WLC). In this three-armed randomized controlled trial (RCT), 69 healthy adults employed in the same organization were randomized to participate in HRV-Bfb, MBI or the WLC. Participants were assessed for psychophysiological parameters of stress (stress perception, coping, HRV parameters and cortisol) and stress related symptoms (depressive symptoms, psychological wellbeing, mindfulness and self-compassion). Participants trained using either HRV-Bfb or MBI for 6 weeks on a daily basis. Outcomes were assessed at baseline, after the intervention and at follow-up 12 weeks later. Results did not show any statistically significant differences between HRV-Bfb and MBI groups, and neither of the intervention groups (IGs) differed from the WLC. Findings suggest an overall reduction in stress for all groups, including the WLC, with mostly small to medium effect sizes. However, it is important to note that participants with higher baseline stress levels might benefit more from mindfulness and biofeedback-based stress reduction interventions. The results have to be interpreted with caution due to the relatively small sample size. MBI might have a slightly stronger effect on stress reduction in comparison to HRV-Bfb, as suggested by the effect sizes. This study highlights issues and challenges of the implementation of such interventions in corporate health management.

RESUMEN

In rural areas, breast cancer-affected patients still do not receive sufficient psycho-oncological care that addresses their specific needs. As a partial solution, telemedicine and web-based applications (eHealth) can add value to their psycho-oncological care as part of self-management regardless of personnel resources, geographical distance from providers, and time constraints. Thus far, however, those supportive aspects of psycho-oncological care are lacking in German-speaking rural areas. For this reason a web-based intervention was developed. Based on the results of a representative cross-sectional and the current literature, we developed a manual and program called Make It Training (Mindfulness and skills based distress reduction in oncology) which was programmed for the websetting. The interactive web-based intervention with 8 sessions integrates different media, including tutorial videos, audio, personal skills box and individual exercises to enhance knowledge about specific disease-related themes. The intervention derives from mindfulness and conveys psychoeducational elements and cognitive behavioural skills with the themes of emotion management, resources, stress management, and self-compassion. The acceptance testing (N=35) showed considerable acceptance and satisfaction. 87% of the patients would recommend the Make it Training to other patient. Prospectively, this training could convey effective strategies for coping with disease-related burden. The Make It Training is an innovative self-management program that can be used for the stepped-care approach and be implemented in rural areas and thereby enhance current outpatient care.

RESUMEN

OBJECTIVES: So far, the effects of vibroacoustic music therapy in cancer patients are unknown. However, used in anthroposophic medicine, it could be an approach to enhance well-being. The goal of this study was to evaluate the immediate effects of a sound-bed music intervention with respect to the subjective well-being as well as body warmth and pain. PATIENTS AND METHODS: We treated 48 cancer patients with 10 min of sound-bed intervention in a cross-over design. Primary outcome was the total sum of the Basler Mood Questionnaire (BMQ), secondary outcomes were subscales of the BMQ and questions addressing body warmth and pain. The EORTC-QLQ C30 was used as baseline assessment for quality of life (QOL). RESULTS: Patients had lower QOL values than the EORTC reference samples (p < .001, d = 0.90). The primary outcome increased after music (p < .001, d = 0.47), no changes were seen in the control condition (p = .73, d = 0.04), the time by condition interaction was significant (p < .05). SECONDARY OUTCOMES: Increase after music for the BMQ subscales inner balance (p < .001, d = 0.73), vitality (p < .001, d = 0.51) and vigilance (p < .001, d = 0.37) as well as for the additional questions satisfaction (p < .001, d = 0.43), current mood (p < .001, d = 0.43), body warmth (p < .05, d = 0.44) and warmth distribution (p < .01, d = 0.49). No significant changes were seen in pain levels and social extroversion. CONCLUSION: Sound-bed intervention improved momentary well-being and caused self-perceived physiological changes associated with relaxation beyond the benefits of simple resting time (control condition). Thus, it might be a promising approach to improve well-being in cancer patients.

RESUMEN

Mindfulness-based interventions have proved effective in reducing various clinical symptoms and in improving general mental health and well-being. The investigation of the mechanisms of therapeutic change needs methods for assessment of mindfulness. Existing self-report measures have, however, been strongly criticized on various grounds, including distortion of the original concept, response bias, and other. We propose a psychophysiological method for the assessment of the mindfulness learned through time-limited mindfulness-based therapy by people who undergo meditation training for the first time. We use the individual pre-post-therapy changes (dERPi) in the event-related brain potentials (ERPs) recorded in a passive meditation task as a measure of increased mindfulness. dERPi is computed through multivariate assessment of individual participant's ERPs. We tested the proposed method in a group of about 70 recurrently depressed participants, randomly assigned in 1.7:1 ratio to mindfulness-based cognitive therapy (MBCT) or cognitive therapy (CT). The therapy outcome was measured by the long-term change (dDS) relative to baseline in the depression symptoms (DS) assessed weekly, for 60 weeks, by an online self-report questionnaire. We found a strong, highly significant, negative correlation (r = -0.55) between dERPi (mean = 0.4) and dDS (mean = -0.7) in the MBCT group. Compared to this result, the relationship between dDS and the other (self-report) measures of mindfulness we used was substantially weaker and not significant. So was also the relationship between dERPi and dDS in the CT group. The interpretation of dERPi as a measure of increased mindfulness was further supported by positive correlations between dERPi and the other measures of mindfulness. In this study, we also replicated a previous result, namely, the increase (dLCNV) of the late contingent negative variation (LCNV) of the ERP in the MBCT group, but not in the control group (in this case, CT). We interpreted dLCNV as a measure of increased meditative concentration. The relationship between dLCNV and dDS was, however, very week, which suggests that concentration might be relatively unimportant for the therapeutic effect of mindfulness. The proposed psychophysiological method could become an important component of a "mindfulness test battery" together with self-report questionnaires and other newly developed instruments.

RESUMEN

Mindfulness meditation as a therapeutic intervention has been shown to have positive effects on psychological problems such as depression, pain or anxiety disorders. In this study, we used functional near-infrared spectroscopy (fNIRS) to detect differences in hemodynamic responses of meditation experts (14 participants) and a control group (16 participants) in a resting and a mindfulness condition. In both conditions, the sound of a meditation bowl was used to find group differences in the auditory system and adjacent cortical areas. Different lateralization patterns of the brain were found in expert meditators while being in a resting state (amplified left hemisphere) or being in mindfulness state (amplified right hemisphere). Compared to the control group, meditation experts had a more widespread pattern of activation in the auditory cortex, while resting. In the mindfulness condition, the control group showed a decrease of activation in higher auditory areas (BA 1, 6 and 40), whereas the meditation experts had a significant increase in those areas. In addition, meditation expert had highly activated brain areas (BA 39, 40, 44 and 45) beyond the meditative task itself, indicating possible long-term changes in the brain and their positive effects on empathy, meta cognitive skills and health.

RESUMEN

BACKGROUND: Many studies suggest that electroencephalographic (EEG) neurofeedback might be beneficial in the treatment of attention-deficit hyperactivity disorder (ADHD). However, numbers of well controlled studies are low and neurofeedback techniques are regarded as highly controversial. The present trial examined the efficacy (compared with sham neurofeedback) and efficiency (compared with meta-cognitive therapy) of a standard EEG neurofeedback protocol in adults with ADHD. METHODS: We did a concurrent, triple-blind, randomised, controlled trial using authorised deception in adults with ADHD from one centre (University of Tübingen) in Tübingen, Germany. Participants were eligible if they fulfilled the DSM-IV-TR criteria for ADHD, were aged between 18 years and 60 years, and had no or stable use of medication for at least 2 months with no intention to change. We excluded participants who had comorbid schizophrenia or schizoaffective disorder, bipolar disorder, borderline personality disorder, epilepsy, or traumatic brain injury; substance abuse or dependence; or current or planned other psychological treatment. Those eligible were randomly assigned to three groups: a neurofeedback group which received 30 verum θ-to-ß neurofeedback sessions over 15 weeks, a sham neurofeedback group which received 15 sham followed by 15 verum θ-to-ß neurofeedback sessions over 15 weeks, or a meta-cognitive group therapy group which received 12 sessions over 12 weeks. Participants were assigned equally to one of the three interventions through a computerised minimisation randomisation procedure stratified by sex, age, and baseline symptom severity of ADHD. Participants were masked as to whether they were receiving neurofeedback or sham neurofeedback, but those receiving meta-cognitive therapy were aware of their treatment. Clinical assessors (ie, those assessing outcomes) and research staff who did the neurofeedback training were masked to participants' randomisation status only for neurofeedback and sham neurofeedback. The primary outcome was symptom score on the Conners' adult ADHD rating scale, assessed before treatment, at midtreatment (after 8 weeks), after treatment (after 16 weeks), and 6 months later. All individuals with at least one observation after randomisation were included in the analyses. This trial is registered with ClinicalTrials.gov, number NCT01883765. FINDINGS: Between Feb 1, 2013, and Dec 1, 2015, 761 people were assessed for eligibility. 656 (86%) were excluded and 118 (15%) were eligible for participation in this study. Eligible participants were randomly assigned to neurofeedback (38 [32%]), sham neurofeedback (39 [33%]), or meta-cognitive therapy (41 [35%]). 37 (97%) individuals for neurofeedback, 38 (97%) for sham neurofeedback, and 38 (93%) for meta-cognitive therapy were included in analyses. Self-reported ADHD symptoms decreased substantially for all treatment groups (B=-2·58 [95% CI -3·48 to -1·68]; p<0·0001) between pretreatment and the end of 6 month follow-up, independent of treatment condition (neurofeedback vs sham neurofeedback B=-0·89 [95% CI -2·14 to 0·37], p=0·168; neurofeedback vs meta-cognitive therapy -0·30 [-1·55 to 0·95], p=0·639). No treatment-related or trial-related serious adverse events were reported. INTERPRETATION: Our findings suggest that neurofeedback training is not superior to a sham condition or group psychotherapy. All three treatments were equivalently effective in reducing ADHD symptoms. This first randomised, sham-controlled trial did not show any specific effects of neurofeedback on ADHD symptoms in adults.

RESUMEN

Verbal thoughts (such as negative cognitions) and sensory phenomena (such as visual mental imagery) are usually conceptualised as distinct mental experiences. The present study examined to what extent depressive thoughts are accompanied by sensory experiences and how this is associated with symptom severity, insight of illness and quality of life. A large sample of mildly to moderately depressed patients (N = 356) was recruited from multiple sources and asked about sensory properties of their depressive thoughts in an online study. Diagnostic status and symptom severity were established over a telephone interview with trained raters. Sensory properties of negative thoughts were reported by 56.5% of the sample (i.e., sensation in at least one sensory modality). The highest prevalence was seen for bodily (39.6%) followed by auditory (30.6%) and visual (27.2%) sensations. Patients reporting sensory properties of thoughts showed more severe psychopathological symptoms than those who did not. The degree of perceptuality was marginally associated with quality of life. The findings support the notion that depressive thoughts are not only verbal but commonly accompanied by sensory experiences. The perceptuality of depressive thoughts and the resulting sense of authenticity may contribute to the emotional impact and pervasiveness of such thoughts, making them difficult to dismiss for their holder.

RESUMEN

UNLABELLED: Functional abdominal pain and irritable bowel syndrome are two prevalent disorders in childhood which are associated with recurrent or chronic abdominal pain, disabilities in daily functioning, and reduced quality of life. This study aimed to evaluate a brief hypnotherapeutic-behavioral intervention program in a prospective randomized controlled design. Thirty-eight children, 6 to 12 years of age, and their parents were randomly assigned to a standardized hypnotherapeutic-behavioral treatment (n = 20) or to a waiting list condition (n = 18). Both groups were reassessed 3 months after beginning. Primary outcome variables were child-completed pain measures and pain-related disability. Secondary outcome variables were parent-completed measures of their children's pain and pain-related disability. Health-related quality of life from both perspectives also served as a secondary outcome. In the treatment group, 11 of 20 children (55.0%) showed clinical remission (>80% improvement), whereas only one child (5.6%) in the waiting list condition was classified as responder. Children in the treatment group reported a significantly greater reduction of pain scores and pain-related disability than children of the waiting list condition. Parental ratings also showed a greater reduction of children's abdominal pain and pain-related disability. Health-related quality of life did not increase significantly. CONCLUSIONS: Hypnotherapeutic and behavioral interventions are effective in treating children with long-standing AP. Treatment success of this brief program should be further evaluated against active interventions with a longer follow-up.

RESUMEN

Meditation-based interventions reduce the relapse risk in recurrently depressed patients. Randomized trials utilizing neurophysiologic outcome measures, however, have yielded inconsistent results with regard to a prophylactic effect. Although frontal brain asymmetry, assessed through electroencephalographic (EEG) alpha activity (8-13 Hz), is indicative of approach vs. withdrawal-related response dispositions and represents a vulnerability marker of depression, clinical trials have provided mixed results as to whether meditation has beneficial effects on alpha asymmetry. Inconsistencies might have arisen since such trials relied on resting-state recordings, instead of active paradigms under challenge, as suggested by contemporary notions of alpha asymmetry. We examined two groups of remitted, recurrently depressed females. In a "mindfulness support group", EEG was recorded during neutral rest, and rest following a negative mood induction. Subsequently, participants received initial meditation instructions. EEG was then obtained during an active period of guided mindfulness meditation and rest following the active period. In a "rumination challenge group", EEG was obtained during the same resting conditions, whereas in the active period, initial meditation instructions were followed by a rumination challenge. A significant shift in mid-frontal asymmetry, yielding a pattern indicative of approach motivation, was observed in the mindfulness support group, specifically during the meditation period. This indicates that mindfulness meditation may have a transient beneficial effect, which enables patients to take an approach-related motivational stance, particularly under circumstances of risk.

RESUMEN

Mindfulness-based cognitive therapy (MBCT) effectively prevents relapse/recurrence in major depression. The ability to deploy and maintain attention on a particular focus is considered as a prerequisite for 'mindful', 'metacognitive' awareness, and hence crucial for therapy success. Accordingly, sustained concentration is the skill most extensively taught in MBCT. The goal of the present study was to test whether this ability increases after MBCT, as assumed. The late component of the contingent negative variation (CNV), an event-related brain potential (ERP), known to reflect the allocation of attentional resources, was used as the measure of concentration ability. In the main phase of the study, 91 recurrently depressed patients in remission were randomly assigned to eight-week treatment by either MBCT or waiting (WAIT for delayed MBCT). The CNV response to an auditory test stimulus was measured pre- and post-treatment in a 'mindfulness task', in which patients were instructed to focus on their breath, as taught in MBCT. The late CNV (LCNV) was increased only after MBCT (and not after WAIT). This result reflects patients' improved ability to shift their attention toward current moment experience and away from potentially depressogenic thinking or rumination during mild dysphoric states-a known risk factor for depressive relapse/recurrence.

RESUMEN

Mindfulness-based cognitive therapy (MBCT), a meditation-based maintenance therapy, reduces the relapse risk in individuals suffering from major depressive disorder (MDD). However, only a few studies investigated the psychophysiological mechanisms underlying this protective effect. We examined effects of MBCT on trait rumination and mindfulness, as indicators of global cognitive style, as well as on residual depressive symptoms in a group of recurrently depressed patients (n=78) in remission. Additionally, alpha asymmetry in resting-state electroencephalogram (EEG) was assessed. Alpha asymmetry has been found to be predictive of affective style and a pattern indicative of stronger relative right-hemispheric anterior cortical activity may represent a trait marker for the vulnerability to develop MDD. In line with previous findings, residual depressive symptoms and trait rumination decreased, whereas trait mindfulness increased following MBCT, while no such changes took place in a wait-list control group. Mean values of alpha asymmetry, on the other hand, remained unaffected by training, and shifted systematically toward a pattern indicative of stronger relative right-hemispheric anterior cortical activity in the whole sample. These findings provide further support for the protective effect of MBCT. In the examined patients who were at an extremely high risk for relapse, however, this effect did not manifest itself on a neurophysiological level in terms of alpha asymmetry, where a shift, putatively indicative of increased vulnerability, was observed.

RESUMEN

OBJECTIVES: To identify predictors of psychosocial adjustment to motor neurone disease. METHODS: A total of 27 individuals with a confirmed diagnosis of amyotrophic lateral sclerosis (ALS) participated in the study. The ALS functional rating scale mean score indicated a high physical impairment of the sample. Months since diagnosis varied between 4 and 129 (median 36). Adjustment outcomes were severity of depressive symptoms and individual quality of life (QoL). Predictors included social support, cognitive appraisal, coping strategies and illness parameters. RESULTS: Multiple regression analysis revealed that approximately 60% of the variance of depression and QoL were accounted for by social support, coping strategies and cognitive appraisal. The degree of physical impairment did not explain any variance of the adjustment outcomes. The best predictors for the severity of depressive symptoms were perceived social support and appraisal of coping potential (internal locus of control) and for individual QoL perceived social support. CONCLUSIONS: The focus on medical issues in treatment of ALS is not sufficient. A palliative approach to ALS must equally imply advice with regards to adequate coping strategies, provide the adequate amount of disease- and support-related information at any one time, and encourage patients to seek social support. Sufficient medication and psychotherapy has to be provided for those patients who show depressive symptoms or disorder.

RESUMEN

Knowledge is limited regarding decision-making about antiretroviral treatment (ART) from the patient's perspective. This substudy of a longitudinal study of psychobiologic aspects of long-term survival, conducted in 2003, compares the rationales of HIV-positive individuals (n = 79) deciding to take or not to take ART. Inclusion criteria were HIV/AIDS symptoms, or CD4 nadir less than 350, or viral load greater than 55,000. Those not meeting any criteria for receiving ART (2/2003 U.S. DHHS treatment guidelines) were excluded. Diagnosis was on average 11 years ago; 36% were female, 42% African American, 28% Latino, 24% white, and 6% other. Qualitative content analysis of semistructured interviews identified 10 criteria for the decision to take or not to take ART: CD4/viral load counts (87%), quality of life (85%), knowledge/ beliefs about resistance (66%), mind-body beliefs (65%), adverse effects of ART (59%), easy-to-take regimen (58%), spirituality/worldview (58%), drug resistance (41%), experience of HIV/AIDS symptoms (39%), and preference for complementary/alternative medicine (17%). Participants choosing not to take ART (27%) preferred complementary/alternative medicine (r = 0.43, p = 0.001)1, perceived a better quality of life without ART (r = 0.32, p < 0.004), and weighted avoidance of adverse effects of ART more heavily (r = 0.24, p < 0.030) than participants taking ART (73%). Demographic characteristics related to taking ART were having a partner (r = 0.31, p < 0.008) and having health insurance (r = 0.26, p< 0.040). Decisions to take or not to take ART depend not only on patient medical characteristics, but also on individual beliefs about ART, complementary/alternative medicine, spirituality, and mind-body connection. HIV-positive individuals declining treatment place more weight on alternative medicine, avoiding adverse effects and perceiving a better quality of life through not taking ART.
