A brief screening tool for suicidal symptoms in adolescents and young adults in general health settings: reliability and validity data from the Australian National General Practice Youth Suicide Prevention Project

Using data from a nationwide project on young people in Australia aimed at assessing suicidality in general health settings, we present a brief screening tool for suicidality (the depressive symptom index suicidality subscale). Two thousand eight hundred and fifty-one (15-24 year old) patients presenting to 247 Australian general practitioners between 1996 and 1998 were assessed. In addition to the suicide screen, patients completed the general health questionnaire-12 and the Center for Epidemiological Studies depression scale. Patients' chief complaints were taken from the summary sheets completed by their general practitioners. Using inter-item correlational and factor-analytic techniques, as well as a general approach to construct validity, we show that the measure has favorable reliability and validity characteristics. We also provide results on cut-points that may facilitate its use in clinical and research settings. Because the screen is brief, easy to use, reliable, and valid, we encourage its use to combat the vexing international health problem of suicide.     

Association between serotonin transporter gene polymorphism and family history of attempted and completed suicide

The purpose of this study was to examine the association of the serotonin transporter gene to family history of suicidality. Forty-seven volunteers responded to questionnaires about family history of suicide, and provided buccal swabs for analysis of the polymorphism. Allelic homozygocity (the short variant) was associated with family history of suicidality. These data, to be interpreted with the study's limitations in mind, suggest a link between the serotonin transporter gene polymorphism and suicide-related variables, which should be the focus of future research.

Development and validation of a brief self-report measure of agitation: the Brief Agitation Measure

Emerging evidence indicates that agitation is an ominous precursor to imminent death by suicide, yet measures of it are few, and to our knowledge, no self-report measure of agitation exists. To fill this gap, we have developed the Brief Agitation Measure (BAM), which is designed as a brief measure to assess agitation. In this article, we provide preliminary evidence from 2 studies examining the reliability and validity of the BAM in an undergraduate sample as well as a clinical sample. We close with a discussion of the limitations of the studies and implications of our findings.     

Examination of racial differences on the MMPI-2 clinical and restructured clinical scales in an outpatient sample

The current study examined the possibility of differential predictive accuracy of selected Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2) clinical and Restructured Clinical (RC) scales in a group of Black and White mental health center clients. Results indicate that Black clients scored higher than White clients on one non-K-corrected clinical scale and 4 RC scales. All these differences produced medium effect sizes and were clinically significant according to Greene's (1987) criterion. These differences, however, were not accompanied by differential predictive accuracy of the scales in Black versus White clients. Although additional research is needed, especially on the RC scales, this study indicates that the MMPI-2 is not a biased predictor of symptomatology for Black versus White test takers.     

Mood Regulation Skill and the Symptoms of Endogenous and Hopelessness Depression in Spanish High School Students

To assess the construct validity of the endogenous subtype of depression, 2 studies examined the relation of mood regulation skill to the symptoms of endogenous depression versus hopelessness depression in adolescent samples. It was hypothesized that the relationship between mood regulation skill and endogenous depression would be weaker than the relationship between mood regulation skill and hopelessness depression, because endogenous depression may be less influenced by personality variables, such as mood regulation skill. In spite of the high degree of correlation between the symptoms of hopelessness depression and endogenous depression, the relationship between mood regulation skill and hopelessness depression was stronger than the relationship between mood regulation skill and endogenous depression, as predicted. This is consistent with proposed definition of endogenous depression.     

Supporting collaboration in virtual learning environments.

Early research argued that computer-mediated communication (CMC) had a number of advantages over existing communication media for supporting collaboration. However, a number of papers emerged that began to raise doubts about this positive view. These papers reported difficulties using CMC to support collaboration. Several systems are reported in this special issue that try to overcome these difficulties, either by changing the communication tools or by developing sound social spaces. These systems are important because the right tools and environment are essential; however, recent research suggests that we need to do more than this, because students do not know how to collaborate effectively and they need to develop these skills to use the tools productively. Other papers in this Special Issue suggest ways this might be achieved.     

Membership in a Devalued Social Group and Emotional Well-Being: Developing a Model of Personal Self-Esteem,Collective Self-Esteem,and Group Socialization

We proposed and tested a theoretical model that links membership in a devalued social group to emotional health. People who identify with devalued social groups (e.g., ethnic minorities, gay men/lesbians, bisexuals, women) may be at increased risk for distress via 3 different pathways. First, some members of devalued groups may internalize negative stereotypes about their group, which negatively impact personal self-esteem. Second, being devalued simply on the basis of one's group membership could lead to emotional distress independent of one's own personal self-esteem. Third, some members of devalued groups may be socialized to develop attitudes and behaviors that increase their risk for emotional distress. Data were collected from a sample of White, middle-to-upper-class undergraduate women and men with respect to personal self-esteem, collective self-esteem on the basis of their gender group, attitudes and behaviors associated with female socialization, and emotional distress. Results supported the direct effect of each pathway in predicting concurrent depression and partially supported the prediction of concurrent anxiety. Each pathway fully accounted for women's greater levels of depression relative to men's. Implications for the study of devalued groups are discussed.
