Using habit reversal to treat chronic vocal tic disorder in children

In the present study, a nonconcurrent multiple baseline design was used to evaluate the effectiveness of simplified habit reversal in three children diagnosed with chronic vocal tic disorder. In two children, vocal tics were substantially reduced. In a third child, tics were not reduced, and the addition of a supplemental contingency management program was ineffective. Despite these mixed results, the treatment was viewed as acceptable to the children's parents in all cases as measured by a standard index of treatment acceptability. Implications of these findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Effect of calories on appetite for palatable food in obese and nonobese humans.

Palatable food stimuli were presented to 11 obese and 11 nonobese male human subjects (in three experiments) 1 hr after ingestion of 900-calorie liquid lunches and (on separate days) indentically tasting 450-calorie liquid lunches of equal volume. Salivary responses to the presentation of the stimuli (i.e., appetite) by the nonobese were inhibited by the high-calorie meal, but those by the obses were less inhibited. Hunger ratings were unaffected by calories in either group. Food stimuli were rated as more appetizing by the nonobese after high-calorie meals, but not so by the obese. Parallels with animal findings suggest that salivary responses reflect lateral hypothalamic activity.     

Reclaiming Evangelism

This paper introduces approaches to reclaiming evangelism, noting the challenges and opportunities of our changing global context, and stressing the importance of authentic witness. The author draws on the Council for World Mission's work promoting the development of missional congregations as life‐affirming communities and its statement identifying six conversation threads (the absence of God; secularism; issues of identity; how we affirm life; the sources we use to shape and nurture our faith; and how we overcome fear and violence in our societies and in the world) that need to be developed on Christian witness in a pluralist world.     

Photographic Assessment of Change in Trichotillomania: Psychometric Properties and Variables Influencing Interpretation

Although photographic assessment has been found to be reliable in assessing hair loss in Trichotillomania, the validity of this method is unclear, particularly for gauging progress in treatment. The current study evaluated the psychometric properties of photographic assessment of change in Trichotillomania. Photographs showing hair loss of adults with Trichotillomania were taken before and after participating in a clinical trial for the condition. Undergraduate college students (N?=?211) rated treatment response according to the photos, and additional archival data on hair pulling severity and psychosocial health were retrieved from the clinical trial. Photographic assessment of change was found to possess fair reliability (ICC?=?0.53), acceptable criterion validity (r?=?0.51), good concurrent validity (r?=?0.30–0.36), and excellent incremental validity (ΔR ²?=?8.67, p?<?0.01). In addition, photographic measures were significantly correlated with change in quality of life (r?=?0.42), and thus could be considered an index of the social validity of Trichotillomania treatment. Gender of the photo rater and pulling topography affected the criterion validity of photographic assessment (partial η ²?=?0.05–0.11). Recommendations for improving photographic assessment and future directions for hair pulling research are discussed.     

An improved spatial span test of visuospatial memory

In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ～30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory.     

Socially Valued Roles,Self‐Determination,and Community Participation among Individuals Living with Serious Mental Illnesses

Decades after deinstitutionalization, individuals living with serious mental illnesses remain isolated, socially disengaged, and devalued members of communities. Burgeoning research and services need conceptual clarity to improve such social conditions. This qualitative inquiry used grounded theory and participatory approaches to conduct an in‐depth exploration of community participation for individuals living with serious mental illnesses based on key stakeholder perspectives (n = 45). Results revealed that community participation is a multifaceted construct with layers of meaning for individuals living with serious mental illnesses. Overarching themes are contextualized in Self‐Determination Theory and presented with deidentified illustrations. Implications for services, research, and policy are discussed.
