Explaining the Relation between Religiousness and Reduced Suicidal Behavior: Social Support Rather Than Specific Beliefs

Religiousness has been associated with decreased risk of suicidal ideation, suicide attempts, and completed suicide, but the mechanisms underlying these associations are not well characterized. The present study examined the roles of religious beliefs and social support in that relation. A survey measuring religiousness, social support, suicidal ideation, and suicide attempts was administered to 454 undergraduate students. Involvement in public, but not private, religious practices was associated with lower levels of both suicidal ideation and history of suicide attempts. Social support mediated these relations but religious beliefs did not. Results highlight the importance of social support provided by religious communities.     

A comparison of trichotillomania and obsessive-compulsive disorder

The validity of conceptualizing trichotillomania (TCM) and obsessive-compulsive disorder (OCD) as separate and distinct diagnoses was examined in a study of 20 patients with each disorder. A comparison of demographic, psychometric, and clinical features between the two groups revealed a number of statistically significant differences. Patients meeting the criteria for OCD scored higher on measures of psychiatric symptomatology including ratings of obsessions and compulsions, depression, interpersonal sensitivity, general anxiety, phobic anxiety, and psychoticism. Patients meeting the criteria for TCM reported an earlier age at onset than those with OCD. Stressors associated with onset were also significantly different between groups. These results support the validity of conceptualizing TCM and OCD as differing behavioral disorders.Portions of this paper were presented at the annual meeting of the Anxiety Disorders Association of America (March 1992) in Dallas, TX, and at the annual meeting of the American Psychiatric Association (May 1992) in Washington, DC.     

Teaching boys with severe mental retardation to serve themselves during family-style meals

Three institutionalized adolescents with severe mental retardation were taught the socially valid skill of serving themselves during family-style meals. A nine-step task analysis was used as a guide for teaching the students, combined with verbal prompts, physical guidance, praise and correction. A multiple base-line design across three subjects was used to evaluate training. All three students successfully acquired the skill, which was seen as a step towards normalization and community placement.     

Friendship,Depression, and Suicide Attempts in Adults: Exploratory Analysis of a Longitudinal Follow‐Up Study

Social support is thought to protect against the risk of suicidal behavior in young people and late life, but less is known about the role of friendship in adults. We explored the effect of friendship on suicide attempt risk during 1‐year follow‐up of 132 adults presenting with major depressive episode (MDE). Items from the Social Adjustment Scale–Self‐Report were used as an index of frequency and quality of recent friendship contacts. Survival methods tested associations of friendship with risk of suicide attempt, recurrent MDE, and related outcomes during follow‐up. Impaired friendship predicted greater risk of suicide attempt in an unadjusted Cox model. This association was stronger for quality (p = .009) than frequency (p = .081) of friendship contacts. In the adjusted model, the effect of friendship on suicide attempts was largely explained by self‐reported depression severity. Friendship has a potentially bidirectional relationship with depression, and its effect on suicidal behavior appears to occur through its relationship with depression. Future research should examine the effect of antidepressant treatment on friendship and be designed to test mediation models of relationships between friendship, depression, and suicidal behavior.     

The perceptual magnet effect in Australian English vowels

Recent research (Kuhl, 1991) has suggested that the internal structure of vowel categories is graded in terms of stimulus goodness. It has been proposed that a best instance stimulus reflects a central point or prototype, which effectively renders within-category members perceptually more similar. Discrimination experiments suggest a nonlinear relationship between acoustic and perceptual space near category centers (Iverson & Kuhl, 1995b). This phenomenon has been described as the perceptual magnet effect. The present study investigated the presence of the perceptual magnet effect in five Australian vowel categories. Australian English speakers identified, rated, and discriminated between a pool of 32 vowel stimuli that varied in F1 and F2 values. The results from Experiments 1 and 2 showed that subjects were able to judge the quality and identify of each stimulus and that a general grading of stimulus quality was reported. This was not symmetrical, and the subjects' responses varied considerably. In Experiment 3, closer control of the methodology in the discrimination task and of contextual factors influencing the test materials was exercised. Despite this, evidence of the warping of perceptual space in discrimination data was not found. In general, these results do not provide support for the existence of the perceptual magnet effect, and explanations for this finding are discussed.
