The effects of Inquiry-Based Stress Reduction (IBSR) on mental health and well-being among a non-clinical sample.

BACKGROUND: Mental problems are highly common among the general population. Mind-body interventions were found to be highly effective in treating them. The current study assessed the effect of Inquiry-Based Stress Reduction (IBSR) meditation on psychological parameters in a general population sample. METHODS: Ninety-seven Participants enrolled in a 28-day workshop and completed a set of self-administered measures before and after the workshop. Outcome measures included Beck Depression Inventory-II (BDI-II), Quick Inventory of Depressive Symptomology-Self Report (QIDS-SR16), Outcome Questionnaire OQ-45.2, The Quality of Life Inventory (QOLI), State-Trait Anxiety Inventory Form (STAI), State-Trait Anger Expression Inventory (STAXI) (State), Subjective Happiness Scale (SHS), Eating Attitudes Test (EAT). RESULTS: BDI scale decreased significantly before and after the intervention. QIDS scale improved significantly from T1 to T2 (p < 0.001). Outcome questionnaire decreased significantly at T2. Quality of life scores improved significantly between T1 and T2 (p < 0.001). Anxiety state and trait scores decreased significantly after the intervention (p < 0.001) All the subscales of anger decreased significantly after the intervention (p < 0.001).Subjective happiness improved significantly (p < 0.001). CONCLUSIONS: IBSR meditation improved various psychological scales among a general population sample. Further controlled studies should evaluate the clinical implementation of IBSR among the general population.

The effects of "The Work" meditation (Byron Katie) on psychological symptoms and quality of life--a pilot clinical study.

OBJECTIVES: "The Work" is a meditative technique that enables the identification and investigation of thoughts that cause an individual stress and suffering. Its core is comprised of four questions and turnarounds that enable the participant to experience a different interpretation of reality. We assessed the effect of "The Work" meditation on quality of life and psychological symptoms in a non-clinical sample. DESIGN: This study was designed as a single-group pilot clinical trial (open label). Participants (n = 197) enrolled in a nine-day training course ("The School for The Work") and completed a set of self-administered measures on three occasions: before the course (n = 197), after the course (n = 164), and six months after course completion (n = 102). OUTCOME MEASURES: Beck Depression Inventory-II (BDI-II), Subjective Happiness Scale (SHS), Quality of Life Inventory (QOLI), Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR16), Outcome Questionnaire 45.2 (OQ-45.2), State-Trait Anger Expression Inventory-2 (STAXI-2), and State-Trait Anxiety Inventory (STAI). RESULTS: A mixed models analysis revealed significant positive changes between baseline compared to the end of the intervention and six-month follow-up in all measures: BDI-II (t = 10.24, P < .0001), SHS (t = -9.07, P <.0001), QOLI (t = -5.69, P < .0001), QIDS-SR16 (t = 9.35, P < .0001), OQ-45.2 (t = 11.74, P < .0001), STAXI-2 (State) (t = 3.69, P = .0003), STAXI-2 (Trait) (t = 7.8, P < .0001), STAI (State) (t = 11.46, P < .0001), and STAI (Trait) (t = 10.75, P < .0001). CONCLUSIONS: The promising results of this pilot study warrant randomized clinical trials to validate "The Work" meditation technique as an effective intervention for improvement in psychological state and quality of life in the general population.

Dichotomous scoring of Trails B in patients referred for a dementia evaluation.

The Trail Making Test is a popular neuropsychological test and its interpretation has traditionally used time-based scores. This study examined an alternative approach to scoring that is simply based on the examinees' ability to complete the test. If an examinee is able to complete Trails B successfully, they are coded as "completers"; if not, they are coded as "noncompleters." To assess this approach to scoring Trails B, the performance of 97 diagnostically heterogeneous individuals referred for a dementia evaluation was examined. In this sample, 55 individuals successfully completed Trails B and 42 individuals were unable to complete it. Point-biserial correlations indicated a moderate-to-strong association (r(pb)=.73) between the Trails B completion variable and the Total Scale score of the Repeatable Battery for the Assessment of Neurological Status (RBANS), which was larger than the correlation between the Trails B time-based score and the RBANS Total Scale score (r(pb)=.60). As a screen for dementia status, Trails B completion showed a sensitivity of 69% and a specificity of 100% in this sample. These results suggest that dichotomous scoring of Trails B might provide a brief and clinically useful measure of dementia status.

Factor analysis of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in a large sample of patients suspected of dementia.

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS; Randolph, 1998) is a popular neuropsychological assessment instrument with research supporting its clinical utility. However, the index structure of the RBANS was derived theoretically and was not based on factor analysis. The purpose of this study was to examine the factor structure in a large heterogeneous sample of patients referred for a dementia evaluation, using exploratory factor analysis. Results suggest a two-factor solution, the first factor defined predominantly as a memory factor and the second as predominantly a visuospatial factor. This study also sought to validate the obtained factors by examining their relationship with external neuropsychological variables. Correlations between the external variables provide further support for Factor 1 as a memory factor. Correlations with Factor 2 support its visuospatial features, although this factor may also be associated with other cognitive domains such as attention and general ability.
