The State-Trait Anxiety Inventory A-Trait Scale: dimensions and their generalization.

The State-Trait Anxiety Inventory A-Trait scale was administered to 152 female and 158 male students. Principal-components factor analyses yielded four orthogonal factors for each sex. The findings indicated that factor pattern comparisons should be made prior to pooling data across sex for psychometric investigations. Also, limited support was found for the generalization of dimensions across sex and samples both within and between cultures.     

The group assessment of interpersonal traits (GAIT): Differentiation of measures and their relationship to behavioral response modes

GAIT performances of undergraduates were rated by peers and professsional clinical psychologists from video tape. Two additional measures; Potential for Clinical Effectiveness, and Insight into the Client's Problem, were included with GAIT measures of Openness, Empathy, Acceptance, and Outgoing and were also rated. GAIT ratings of Empathy, Acceptance, Potential for Clinical Effectiveness were not well differentiated. The behavioral response modes of each participant in the Understander's role were analyzed and correlated with GAIT measures, Potential and Insight. Empathy was correlated with reflecting feelings and advice-giving questions and negatively correlated with dysfunctional questions and silence. Acceptance was correlated with nonverbal attending behavior and negatively correlated with dysfunctional questions. Outgoing was positively correlated with information-gathering questions and total questions. Insight was correlated with reflecting feelings and negatively correlated with silence. An Understander who was rated high on Potential for Clinical Effectiveness was active, made statements about or asked questions pertaining to the Discloser's feelings, asked advice giving questions, tended to have infrequent silences during the interaction, and did not ask digressive or dysfunctional questions. Finally, the importance of Outgoing suggests the salience of an activity dimension in judged Clinical Potential.     

Knowledge and beliefs about depression among urban and rural Indian Malaysians

This study was concerned with mental health literacy specifically with regard to depression. It aimed to investigate “depression literacy” in a sample of urban and rural Indians in Malaysia. A total of 314 participants completed a survey that examined knowledge about depression using a vignette-identification method, and ratings of statements about causes and treatments for depression. The vignette-identification task showed that urban participants were more likely than rural participants to identify depression as such. Only a small minority of rural participants recognised the disorder, using the actual term depression. Factor analysis of the causes and belief items revealed a number of distinct factors, of which trauma and stress were the most strongly endorsed causal factor. For treatment, religious observance and lifestyle factors were rated highly by both groups. The findings suggest that information campaigns are needed to increase the level of awareness about depression targeting the rural population. Limitations are considering including possible ethnocentric biases. The implications of these results are considered.     

Decisions to donate bone marrow: The role of attitudes and subjective norms across cultures

Abstract

This paper reports the results of a field investigation of the determinants of decisions to donate bone marrow. Predictions are made on the basis of a modification of the theory of reasoned action wherein attitudes are operational-ized in separate affective and evaluative components. Boundary conditions of the theory of reasoned action are further explored by examining the effects of culture (Hong Kong Chinese, N= 190; American Chinese, N = 107; black Americans, N = 124; and white Americans N = 122) on decisions to donate for each of four targets: Immediate Family Members (TFM), Close Relatives (CR), Ethnic Strangers (ES), and Total Strangers (TS). For this life or death decision, the willingness to give is hypothesized to vary as a function of the so-called fitness value of the recipients (i.e., their capacity to contribute to the donor's inclusive fitness), as modified by cultural differences between group- versus independent-based cultures. Among other results, the following gradient was found in attitudes, subjective norms, and intentions for Chinese: IFM > CR > ES > TS; for Americans the pattern was IFM = CR > ES = TS. American Chinese showed stronger attitudes and felt norms, but not intentions, to give to close relatives than did Hong Kong Chinese, reflecting differential in-group/out-group pressures. Black and White Americans showed stronger attitudes, subjective norms, and intentions to donate to strangers than did Chinese.     

Confirmatory Factor Analyses of Scores From Full and Short Versions of the Marlowe–Crowne Social Desirability Scale

Self-report measures are much used in social psychology. However, such measures are susceptible to response bias. The 33-item Marlowe–Crowne Social Desirability scale (Crowne & Marlowe, 1960) is widely used to detect social desirability in responding. This study used confirmatory factor analyses and item and scale analyses to evaluate different, time-saving, short versions of the scale. The results from 633 management undergraduates showed that all the short versions and the 2-factor model are a significant improvement in fit over the full scale. There were no gender differences on the 14 measures. It is recommended that when the full scale is used, the separate attribution and denial scores are also used. Researchers who decide to use a short version should seriously consider Ballard's (1992) Scale 1 or composite versions because the present study identified these as the best short versions.     

Strain‐specific aggressive behavior of male mice submitted to different husbandry procedures

Severe aggression within groups of male laboratory mice can cause serious welfare problems. Previous experiments have shown that the transfer of specific olfactory cues during cage cleaning and the provision of nesting material decrease aggression and stress in group‐housed male mice. In this study, the combined effect of these husbandry procedures was tested for their long‐term effect on aggression in two strains of male mice (BALB/c and CD‐1). We used postcleaning aggressive behavior, wound counts, and testosterone levels as indicators of aggressiveness. Physiological responses to social challenge were investigated through urinary corticosterone and adrenal tyrosine‐hydroxylase measurements. Furthermore, the aggression‐modulating effects of two enrichment items (ShepherdShack/DesRes and PVC tube) were explored. Marked differences were found between the two strains. CD‐1 mice were more aggressive, had higher testosterone levels but lower corticosterone levels, and had fewer wounds than BALB/c mice. However, in neither of the two strains was long‐term enrichment with nesting material and its transfer after cage cleaning effective in lasting reduction of intermale aggression. This may be explained by the fact that aggression levels were generally low. It seems that housing mice in small, socially stable groups or keeping social disturbances to a minimum considerably modulates aggression in group‐housed male mice. Mice of both strains housed in cages enriched with nesting material had lower urinary corticosterone levels than standard‐housed mice. We therefore conclude that the long‐term provision of nesting material, including the transfer of nesting material during cage cleaning, may enhance the welfare of laboratory mice. Aggr.

A dynamical systems analysis of spontaneous movements in newborn infants

The authors evaluated the characteristics of infants' spontaneous movements by using dynamical systems analysis. Participants were 6 healthy 1-month-old full-term newborn infants (3 males, 3 females). They used a triaxial accelerometer to measure limb acceleration in 3-dimensional space. Acceleration signals were recorded during 200 s from the right wrist when the infant was in an active alert state and lying supine (sampling rate 200 Hz). and was stored in the system's memory. Digitized data were transferred to a PC for subsequent processing with analysis software. The acceleration time series data were analyzed linearly and nonlinearly. Nonlinear time series analysis suggested that the infants' spontaneous movements are characterized by a nonlinear chaotic dynamics with 5 or 6 embedding dimensions. The production of infants'spontaneous movements involves chaotic dynamic systems that are capable of generating voluntary skill movements.
