Contributors to suicidal ideation among bipolar patients with and without a history of suicide attempts

This study was designed to develop models for vulnerability to suicidal ideation in bipolar patients. Logistic regression models examined correlates of suicidal ideation in patients who had versus had not attempted suicide previously. Of 477 patients assessed, complete data on demographic, illness history, and personality variables were available on 243. The regression models achieved positive predictive values of 55% and 59% for the attempter (N = 92) and nonattempter groups (N = 151), respectively. Depression was cross-sectionally associated with suicidal ideation in both the attempter and nonattempter groups but made a smaller contribution among attempters. Poor psychosocial adaptation and the personality factor "openness" were stronger contributors to suicidal ideation among prior attempters while anxiety and extraversion appeared protective against ideation. Among nonattempters, depression, anxiety, and neuroticism were the predominant influences on suicidal ideation. Bipolar patients with suicidal ideation may benefit from different treatment strategies depending on their prior attempt status.     

Using a small sample Q sort to identify item groups

A small sample of 40 second-year university students in Hong Kong were asked to perform a Q sort on the 36 items of a questionnaire used to assess six dimensions of student approaches to learning, the Learning Process Questionnaire. Participants were instructed to sort the items into as many groups as they liked with the only conditions being that all items within a group be as similar as possible in perceived meaning and that no item be placed into more than one group. By treating participants' responses as a form of multiple-choice data and by applying optimal scaling, three solutions were obtained. A two-dimensional plot of the optimal item scores for the first two solutions yielded 10 clearly defined item clusters suggesting a possible ten-factor model as opposed to the six-factor model found in studies of this questionnaire. The implications of using this approach to identify potential competing factor models, especially within a cross-cultural context, are discussed.     

Effects of noise on pure-tone thresholds in blackbirds (Agelaius phoeniceus and Molothrus ater) and pigeons (Columba livia)

Blackbirds and pigeons were trained to detect tones in quiet and in broadband noise by using positive-reinforcement techniques. In Experiment 1, thresholds in noise were obtained in blackbirds as a function of both tone frequency and noise intensity for a pulsed noise masker (noise gated on and off with tone). For blackbirds, critical ratios (the ratio of the power of the just-detectable tone in noise to the power of the noise masker) obtained in pulsed noise showed no consistent relation to tone frequency. For pigeons, on the other hand, critical ratios obtained in continuous noise increased by about 3 dB/octave across their range of hearing, being similar to known critical ratio functions for cats and humans. In Experiment 2, critical ratios in blackbirds obtained with both continuous noise and pulsed noise were compared. Blackbird critical ratios were more stable in continuous noise and averaged 4 dB lower than critical ratios in pulsed noise. The blackbird critical ratio function obtained with continuous noise was similar to the known critical ratio function of another avian species, the parakeet. Thus, small birds appear to have atypical critical ratio functions, compared with pigeons and other vertebrates.     

Systemic strategies for dealing with problem children in institutional settings

Family therapy when a problem child enters residential treatment is complicated and treacherous because of the need to coordinate what may often be competing hierarchies (parental, residential, school). If the goal of residential treatment truly is one of deinstitutionalization, of reintegrating the child into his/her home, school, and community, the family therapist must see to it that the parental hierarchy is the primary one and that all institutional hierarchies are kept secondary. This paper presents, through a discussion of the forces that operate as institutionalization of children progresses and through case illustrations, a framework in which family therapy can be conducted within a residential treatment setting.The author expresses appreciation to Barbara DiCocco, MSW, Phyllis Stern, MA, John Rhead, PhD, and Karen Meckler, MD, for their helpful comments on the initial draft of this article and to Linda McClure, MSW, and Larry McAvoy for their administrative support.     

Physical stigma and the pregnancy role: Receiving help from strangers

Previous research has demonstrated several similarities in the reaction of others to pregnant and to physically stigmatized individuals. This study recorded helping behavior (assistance in picking up scattered keys) directed toward an apparently pregnant, nonpregnant, or facially disfigured woman in an elevator either alone, with a female companion, or with a male companion. A predicted interaction revealed that significantly more assistance was given to the pregnant woman than to either of the other two only when she was alone or with a female companion; she was helped less than the non-pregnant experimenter when she was accompanied by a male. Differences and similarities in the norms that govern behavior toward pregnant women and the physically stigmatized are discussed in light of their relevance to women's development during the childbearing years. The well-documented negative effect of group size on helping was replicated. Unexpected sex differences were found in rate of helping. Women virtually never helped in this situation—even in all-female groups. These findings are discussed in light of previous work on sex differences in helping.Preparation of this article was supported by a faculty development grant awarded to the first author by Rhodes College. We wish to thank Bella DePaulo, Robert Vidulich, and Chris Wetzel for their helpful comments on an earlier draft of the paper.     

Maternal employment,anxiety, and sex differences in college students' self-descriptions

This study sought to determine if a relationship exists between maternal employment during childhood, anxiety, and gender in college students. A questionnaire incorporating the Adjective Generation Technique (AGT) was administered to undergraduate psychology students from intact, two-parent families. Subjects were grouped into four categories: males whose mothers worked during their childhood (n=33), males whose mothers remained home (n=49), females whose mothers worked (n=54), and females whose mothers remained home (n=49). Data were analyzed using a 2×2 analysis of variance. Results indicated no differences in anxiety for subjects of either sex in relationship to the employment status of the mothers. A pronounced sex difference was found, with females scoring significantly higher in anxiety than males.     

Personality dimensions in patients with sleep-apnea syndrome: comparison with narcolepsy

Personality measures of Anxiety-Neuroticism, Extraversion and Socialization obtained from self-report questionnaires were studied in a group of sleep-apnea patients (15 males, 5 females), and compared with results from a normal control group (63 males, 21 females) and a group of narcoleptic patients (17 males, 32 females). Sleep-apnea patients were significantly higher in Anxiety-Neuroticism and slightly higher in Extraversion than controls. Although the main symptom, i.e. excessive daytime sleepiness, of sleep-apnea and narcoleptic patients is similar, there were distinct differences in pattern of personality measures. Sleep-apnea patients were lower in Anxiety-Neuroticism and higher in Extraversion. Thus, increased sleepiness alone did not induce uniform changes in personality traits in the two patient groups. It is suggested that the particular personality profile of the sleep-apnea patients is secondary to increased psychosocial strain and coping strategies to keep awake. In contrast, the high Somatic Anxiety scores and low Socialization scores in the narcoleptic group are assumed to reflect a constitutional lability which also involves autonomic and sleep functions.
