Effects of Transcendental Meditation on self-identity indices and personality

Cognitive Orientation toward Positive Values in Advanced Participants of the TM and TM-Sidhi Program

The results of two studies, with 15 and 10 college students practicing the Transcendental Meditation (TM) and TM-Sidhi program (ages: M = 28 yr.; M = 29 yr.), and 10 and 9 controls (ages: M = 22.9 yr.; M = 26.2 yr.), respectively, indicate that advanced participants of the TM and TM-Sidhi program may have a cognitive set oriented toward more positive values. Subjects in the TM-TM-Sidhi program exhibited a better recall of positively valued words than the control group in a long-term memory task (45 min.), and they needed fewer exposures to recognize positive than negative words at lower absolute thresholds than the controls in a tachistoscopic experiment. They appraised “significant others” more favorably than the control group on LaForge's Interpersonal Checklist, while self-appraisal was high in both groups. A third study of 11 college students, M age of 22.3 yr., yielded an inverse relationship between differential recognition thresholds for positive and negative affect terms on a tachistoscopic task and the reported experienced intensity of the corresponding affects. This suggests that enhanced perception of certain affect terms may be a function of more frequent experiences of those affects.

Mindfulness meditation and explicit and implicit indicators of personality and self-concept changes

The scientific interest on mindfulness meditation (MM) has significantly increased in the last two decades probably because of the positive health effects that this practice exerts in a great variety of clinical and non-clinical conditions. Despite attention regulation, emotional regulation, and body awareness have been argued to be critical mechanisms through which MM improves well-being, much less is known on the effects of this practice on personality. Here we review the current state of knowledge about the role of MM in promoting changes in practitioners’ personality profiles and self-concepts. We first focus on studies that investigated the relations between mindfulness and personality using well-known self-report inventories such as the Five-Factor model of personality traits and the Temperament and Character Inventory. Second, based on the intrinsic limitations of these explicit personality measures, we review a key set of results showing effects of MM on implicit, as well as explicit, self-representations. Although the research on MM and personality is still in its infancy, it appears that this form of meditative practice may notably shape individuals’ personality and self-concept toward more healthy profiles.

Mindfulness-oriented meditation improves self-related character scales in healthy individuals

Previous studies have shown that mindfulness meditation may improve well-being in healthy individuals and be effective in the treatment of mental and neurological disorders. Here, we investigated the effects of an 8-week mindfulness-mediation program on the personality profiles of three groups of healthy individuals with no previous experience with meditation as compared to a control group not enrolled in any training. Personality profiles were obtained through the Temperament and Character Inventory (Cloninger et al., 1993). In the experimental groups, significant increments after the training were obtained in all the three character scales describing the levels of self maturity at the intrapersonal (Self-Directedness), interpersonal (Cooperativeness), and transpersonal (Self-Transcendence) levels. No changes were found in the control group. Strikingly, these effects were significant only in those groups who were engaged in consistent daily meditation practice but not in the group who attended the meditation training but were less consistent in home practice. Since higher scores in the character scales are associated to a lower risk of personality disorder, we propose that the increase of self maturity after the training may be an important mechanism for the effectiveness of mindfulness-oriented meditation in psychotherapeutic contexts.

Identity change and the human dissection experience over the first year of medical training

The aim of this study is to explore identity change in medical students over their first year of medical training, particularly in relation to their experience of human dissection. Each of our four participants completed two repertory grids at the end of term one and, again, towards the end of term three. One grid tapped their identity construction, and the other, their experience of human dissection. Our participants were optimistic about becoming similar to a doctor they admired and, towards the end of term three, began to develop a stable identity as a medical student. Their identity constructs involved three common themes: dedication, competence, and responsibility. However, the data also revealed negative reactions to the demands of training, such as feeling driven and stressed. Three major themes were apparent in their experience of human dissection: involvement, emotional coping, and ability. Our participants' dedication to their studies was reflected in their appreciation of the need to become involved actively in the process of dissection but some experienced an erosion of their self-confidence and perceived some of their colleagues to have lost much of their enthusiasm for learning. Emotional coping could be an additional challenge within this context and their reaction tended to reflect distancing processes previously identified in the literature. In all, we see a development of a vulnerable sense of professionalism alongside a frustration of losing out potentially on wider aspects of personal development due to the high work demands.

Effectiveness of the Transcendental Meditation program in preventing and treating substance misuse: a review

This article reviews 24 studies on the benefits of Transcendental Meditation (TM) in treating and preventing misuse of chemical substances. Studies cover noninstitutionalized users, participants in treatment programs, and prisoners with histories of heavy use. All the studies showed positive effects of the TM program. Some of the survey-type studies were unable to exclude the possibility of self-selection or responder biases. However, longitudinal, random-assignment studies with objective measures also showed positive results. Taken together, these and other studies indicate the program simultaneously addresses several factors underlying chemical dependence, providing not only immediate relief from distress but also long-range improvements in well-being, self-esteem, personal empowerment, and other areas of psychophysiological health.

Transcendence and psychological health: studies with long-term participants of the transcendental meditation and TM-Sidhi program

We investigated the nature of the relationship between experiences of transcendental consciousness and psychological health. In Study 1, three groups with different levels of experience in transcendental meditation (TM) and in the TM-Sidhi program (techniques that have been shown to produce experiences of transcendental consciousness) were studied, using the self-investigation method of Hermans (1976). We employed blind interviewers and raters with various attitudes toward TM to minimize the possible impact of a variety of artifacts. Cross-sectionally, experience with TM and the TM-Sidhi program was positively related to a general measure of psychological health (p = .002); longitudinally, the meditating groups improved more than the control group on the psychological health measure (p less than .03). In Study 2, two contrast groups of long-term participants were similar on several confounding variables but differed on physiological indicators of experiences of transcendental consciousness. The groups with the positive physiological indicators showed a trend toward higher scores on the psychological health factor (p = .092), indicating that psychological health may be developed through the systematic cultivation of transcendental meditation and the TM-Sidhi program.
